Electromechanical installation is the main part of hydropower station construction project, and its construction quality directly affects the energy-saving effect, function and stable and safe operation of hydropower station. In recent years, the continuous progress of electromechanical installation technology has promoted the popularization of electromechanical installation engineering in public, industrial and civil fields, with emphasis on electrical engineering, intelligent engineering and automation instrument engineering. In addition, China has also strengthened the management of the overall quality of the electromechanical installation project of hydropower stations, but there are still problems in the electromechanical installation project. Therefore, it is necessary to strictly manage the quality of electromechanical installation and effectively improve the management level, so as to ensure the overall quality of electromechanical installation of hydropower stations [1-3].
1 characteristics of electromechanical installation project of hydropower station
Most of the electromechanical installation projects of hydropower stations are located in deep mountains and valleys, with harsh geographical conditions, complicated traffic and difficult conditions. At the same time, the project involves a wide range of subjects. Usually, the construction process begins with equipment procurement, involving equipment debugging, production operation, completion acceptance and other stages until it can meet the application function and even normal production. At present, with the continuous expansion of industrial scale, some new technologies, new processes and new materials are constantly emerging, which puts forward higher requirements for the electromechanical installation technology and management of hydropower stations. Compared with the acceptance of construction projects, there are obvious differences in the construction quality acceptance of electromechanical installation projects, which are generally manifested in the differences in quality evaluation methods, project acceptance and after-sales service methods. In this respect, the main characteristics of electromechanical installation of hydropower station are the difficulty of construction, long construction period and difficult project management.
2 problems existing in electromechanical installation engineering
(1) unscientific business and process management makes it difficult to achieve cross-departmental coordination. Generally speaking, the owners are mainly concerned about the progress, investment and quality, but the most important thing is the effective communication of information. Because there are many units and departments involved in project management, the traditional information communication methods such as meeting and issuing documents have been difficult to meet the requirements. The information transmission efficiency of these methods is relatively low, and there are many problems in communication. If management is difficult to form a system, even if the division of labor is fine, data, conditions, materials and other related information can not be shared and shared in a short time, and there is a lack of effective combination with IT technology. Therefore, the reduction of staff has not increased the effect, and sometimes it is necessary to increase staff. Relevant personnel often shirk their responsibilities after finding problems, resulting in low work efficiency. Adopting matrix management mode depends not only on management system, but also on IT network and * * * sharing mode to improve economic benefits to a certain extent. In this regard, we should create a management process centered on project objectives and contracts, that is, after signing the contract, all rights and obligations of the construction parties must be strictly implemented in accordance with the contract requirements, and the design progress, procurement progress and project quality should also be guaranteed by contracts. (2) There are many related projects, so it is difficult to achieve effective management and monitoring. In the past, related management lacked the management of project scope and project system, mainly because of the insufficient analysis of process design and project management, which led to the large or small scope of sub-projects. With the wide application of information technology, the schedule management, contract management and quality management of mechanical and electrical installation projects have entered a new period, and simpler and more convenient management methods can be used to enable managers to solve problems more efficiently and effectively alleviate the repetitive work of project managers to some extent. (3) Lack of information system. In the past, information technology, project management software and project management process were not integrated into an effective information system, which made it difficult to form network benefits, feedback benefits and management knowledge benefits, resulting in low operational efficiency. If the relevant leaders know the project status through business trips and reports, it will lead to insufficient control over the corresponding design, construction, supervision and other construction enterprises, and it is difficult to form effective internal control, which will lead to great risks. (4) It is difficult for leaders to deeply understand the enterprise situation and lack the basic support for decision-making. Relevant data such as progress, investment and contract in the project are not only large but also constantly changing, which is difficult for the owner to master and even more difficult to summarize. In the process of project management, it is difficult to effectively integrate project process and information technology, which greatly affects work efficiency. If information technology is used to assist decision-making management, remote control and decision-making can be realized, project management cost can be reduced to a certain extent, and management efficiency can be effectively improved. (5) It is difficult to share and accumulate knowledge and experience among construction enterprises, and the necessity of project experience is low. Due to the lack of an operating platform for overall project knowledge management, it is difficult to share knowledge and experience between projects and enterprises. Using information technology to create engineering project knowledge base can provide a good platform for knowledge accumulation, enjoyment and innovation, thus realizing the arrangement, storage and release of all kinds of knowledge within enterprises.
3 hydropower station electromechanical installation project management points
(1) quality management. The quality management of electromechanical installation project of hydropower station must have a relatively perfect quality control management system, and strengthen quality management and control from the aspects of project entity formation period, construction level and construction technology. In this regard, it is necessary to establish a project quality control management system with the project manager as the main body and the participation of project engineers, heads of relevant functional institutions and subcontractors [4-5]. (2) schedule management. The electromechanical installation project of hydropower station is a complicated process, and its construction management needs to cooperate not only with the main construction of civil engineering, but also with the decoration construction, so the construction progress of electromechanical installation project must be guaranteed. In this regard, the project organization should establish a project construction progress control system with the project manager as the main body of responsibility, including the deputy production manager, the person in charge of the contract budget organization and subcontractors, and strictly implement technical and economic measures to ensure the construction accuracy. (3) cost management [6]. (1) Complete the breakdown of the cost plan formulated by the enterprise according to the engineering parts and cost items, find all ways and countermeasures to reduce the cost, formulate the detailed list of the target cost plan and the target cost control schedule, and strictly implement it to the corresponding person in charge at the same time, regularly check and improve the established cost control plans and countermeasures. (2) Establish a detailed list of all project cost income and expenditure according to the location and cost of the project, record the cost in construction item by item, and make monthly settlement, and compare and evaluate the completion of the planned target cost at the same time. (3) According to the management control plan of target cost, leaders at all levels are required to plan and arrange the required materials, equipment and machinery in advance, and the project department makes unified scheduling and careful planning for all production factors, striving to achieve optimal configuration, rational use and dynamic management, so as to prevent shutdown, slowdown and inefficiency caused by poor planning or blind scheduling. (4) Safety management. ① Create an organization department. The project department should establish an all-round, whole-process and full-staff advanced safety management system, in which the project manager is the overall person in charge of the safe and stable production of the project, and the deputy production manager and chief engineer are the direct persons in charge of the safe and stable production of the project. In addition, all functional organizations are horizontally included, and all staff members are vertically included, and all staff members bear specific written safety responsibilities. ② Make a safety management plan. The Project Department shall organize relevant technical personnel to formulate the safety construction scheme and design of electromechanical installation project, formulate the safety construction countermeasures for special projects or some projects, formulate the safety technical schemes and countermeasures for single projects such as water pump house, cooling tower house and generator room, deeply analyze the hidden dangers of the project, and plan and arrange from the aspects of materials, equipment and technology to ensure the normal development of safety construction.
4 Strengthen the quality of electromechanical installation project of hydropower station
(1) Strengthen the coordination and management during the construction of electromechanical installation project. Coordination management must be strengthened in the construction design of electromechanical installation project of hydropower station to ensure the accuracy, scientificity and credibility of construction design drawings. At this stage, the designers of the electromechanical installation project of hydropower station should complete the construction inspection of the scheme, and at the same time effectively feed back the inspection results to the construction design scheme, especially the design of corresponding key points, such as the embedment of wall-penetrating pipelines, the embedment of electrical devices, the embedment of line fixtures, etc., and must make specific marks on these key points in the construction drawing, including design technical parameters, product technical parameters, optional manufacturers, etc. In addition, before construction, construction enterprises and construction design units should seriously negotiate construction design drawings, strictly review the feasibility of electromechanical devices and civil engineering, and ensure the overall construction safety and quality of the project. It is also necessary to strengthen the professional and technical training of mechanical and electrical installation personnel, to ensure that building civil engineering enterprises and equipment safety enterprises can cooperate effectively, and to ensure that the project quality and construction progress are truly and effectively reflected on the engineering drawings. (2) Strengthen multi-party coordination of construction scheme. There are often differences in construction period and technical requirements between electromechanical installation of hydropower station and civil construction enterprises. The embedded and preset positions must be consistent with the corresponding technical parameters of equipment installation, and the organization and coordination of construction schemes should be strengthened to avoid potential problems. In the process of concrete pouring, civil construction enterprises should ensure that the corresponding reserved parts of the installation project are consistent with the relevant technical parameters of the embedded points. In addition, the construction of concrete pouring, formwork erection and vibrating will also cause the displacement of embedded points, which must be corrected in time to ensure the cleanliness of the environment near the installation of mechanical and electrical equipment. At the same time, there are many types of work on the construction site, such as architectural decoration and construction machinery, so it is necessary to organize and coordinate the interests of all parties to ensure the normal and orderly construction period. (3) Strengthen cooperation in infrastructure projects. During the construction of basic projects, it is necessary to strengthen the cooperation of construction enterprises. During this period, the construction workers of the electromechanical engineering project of hydropower station should cooperate closely with the civil works, especially the corresponding reservation and embedment of auxiliary water inlet and outlet channels, cable pipes and lightning wires. It should be noted that when designing large-scale caverns of hydropower projects or involving structural safety, specific marks should be made in civil construction drawings, especially the corresponding technical parameters, and civil construction enterprises are required to strictly implement them. In addition, for the reserved holes related to the installation of electromechanical equipment of hydropower station, before the civil construction, the civil construction personnel should conduct in-depth and specific consultations with the electromechanical installation personnel to complete the specific comparative analysis of the technical parameters of the drawings and product specifications. On the basis of ensuring no leakage of holes, the corresponding technical parameters such as the position, elevation and size of reserved holes can meet the requirements of electromechanical equipment installation of hydropower stations, so as to prevent rework caused by problems in later technical specifications. The electromechanical installation project of hydropower station should also actively cooperate with the construction progress requirements of relevant civil engineering enterprises, and effectively reserve all civil engineering pipelines, especially the holes and pipelines that civil engineering enterprises may need during construction, which are not marked in the drawings. Ensure that cable supports, pipe supports, cable trays and other related embedded parts are installed before civil construction. (4) Improve the informatization level of electromechanical installation management of hydropower stations [8]. The electromechanical engineering project construction of hydropower station is a complex project, with large quantities, many processes and long construction period. It is necessary to strengthen the role of information management in the management of electromechanical installation project of hydropower station. The electromechanical installation project of hydropower station mainly includes the procurement of engineering materials and equipment and the technical processing of corresponding data such as technical files. Therefore, a special mechanical and electrical installation engineering database should be established to detect the corresponding project implementation progress and quality. In addition, with the continuous development of social economy and the improvement of information level, the openness and complexity of electromechanical installation project of hydropower station are obviously improved. In this regard, we must make full use of information technology, bring important links of related projects such as construction organization into the information management platform, and implement unified management to ensure the management level and overall quality of electromechanical construction of hydropower stations.
5 conclusion
Electromechanical installation of hydropower station is an industry operated and realized by people with professional technical ability, so meticulous project management is particularly important. As the management foundation of an enterprise, project management should take safety production as the construction foundation of the project and the construction period as the guarantee of operation efficiency. At the same time, we should take quality as an important principle and management concept in creating and maintaining corporate brands, strengthen budget management and quantity settlement in target planning, optimal allocation and implementation, and implement refined management in all aspects to improve management efficiency.
