1 china municipal engineering construction quality control design
In the process of engineering construction, the most important link is the quality of engineering construction. In the process of construction project management, the on-site construction project manager should take the construction quality as the key work. On-site management personnel should manage and control every item of construction, and at the same time make clear the main body responsible for construction quality. In the process of construction, we must check and control the requirements related to design and relevant national industry standards. In case of quality problems in the process of engineering construction, the site supervisor and the owner's personnel shall go to the construction site for on-site quality acceptance. Once it is determined that there are quality problems in the construction, it is necessary to re-construct.
2 the main measures of information construction management in the process of municipal engineering construction
In municipal road engineering, every construction project will be replaced and cross-constructed very frequently in the construction stage. In this case, it is necessary to ensure the effective and efficient operation of site construction and have a detailed construction information management process. On-site management personnel should pay enough attention to each subdivisional work and effectively transfer each working procedure. This paper expounds and analyzes the main measures of information construction management in the process of municipal engineering construction, and the article mainly expounds them from two aspects. The first aspect is that in the construction of municipal road projects, it is necessary to continuously establish information construction management related processes. The second is to implement the management of engineering information classification system in the construction of municipal road projects. The following is a detailed description and analysis.
2. 1 In the road engineering construction of municipal engineering, it is necessary to continuously establish the relevant processes of information construction management.
In the process of municipal engineering road construction, the information management in the construction process should be managed as the main work. We should ensure that all construction preparations and reserves are in place during the construction period. Equipment configuration, schedule control, safety management and quality management in construction. It should be implemented in an orderly manner. In the process of municipal road construction, all kinds of construction information should be standardized and constantly demonstrated. Through constant argumentation, the normal and high-quality construction is ensured. Let the whole municipal road project meet the construction quality requirements.
2.2 In the construction of municipal road engineering, engineering information classification system management should be implemented.
This paper expounds and analyzes the classified system management of engineering information in municipal road engineering construction, mainly from six aspects. The first aspect is the information management of passage construction in municipal road engineering. The second aspect is the cost information management of municipal road engineering. The third aspect is the progress information management of municipal road engineering. The fourth aspect is the quality information management in municipal road engineering. The fifth aspect is the contract information management in municipal road engineering. The sixth aspect is the transaction information management in municipal road engineering.
2.2. 1 municipal road engineering tunnel construction information management. In the process of road access construction, foundation pit construction is the most important. In the meantime, in order to effectively prevent pavement surface settlement and protect surrounding buildings. We should control and manage information in the whole construction process. In the process of tunnel construction, the main task of information control and management is to use relevant instruments or means to ensure that the monitoring results of the surface are accurately and timely conveyed to the construction personnel, and to effectively classify and save the construction information.
2.2.2 Cost information management in municipal road engineering. In the process of construction, in order to maximize the use of resources in the project and realize value. Municipal road engineering cost information management should start from five aspects. The first aspect is to manage costs from a technical point of view; The second aspect is to manage the cost from the perspective of equipment management; The third aspect is to manage costs from the perspective of material management; The fourth aspect is to manage costs through the effective use of funds; The fifth aspect is to manage costs through the effective use of manpower. We should make an effective comprehensive analysis of these five aspects, and constantly analyze and optimize the project cost information management in these five aspects, so as to effectively ensure the effective utilization of project construction resources.
2.2.3 Progress information management of municipal road engineering. In municipal road engineering, schedule control and management is a very important work, so it is necessary to ensure that the construction progress of the project is completed in advance or on schedule. In view of the doubtful points or difficult construction projects in the construction process, it is necessary to solve and deal with them in time to ensure that the overall construction progress will not be affected. In the process of connecting each working procedure, the handover time of each working procedure should be shortened as much as possible to effectively improve the utilization rate of construction equipment. 2.2.4 Municipal Road Engineering Quality Information Management. In the process of municipal road construction, there are many aspects of quality information management. Foundation pit safety control, foundation pit waterproof control, anti-floating control and management of main structure, measurement quality management, etc. Everyone needs attention. In the construction, corresponding modification and optimization should be made according to the construction data.
2.2.5 contract information management of municipal road engineering. In the road engineering construction contract, the content of construction information feedback is clearly defined. In the process of construction, the relevant data of construction should be effectively notified and conveyed to the site supervisor and the site owner. Follow-up work can only be carried out after obtaining the owner's permission or instruction. 2.2.6 Transaction information management in municipal road engineering. Transaction management information includes the management of contract execution process documents, superior documents, materials, meeting minutes, internal correspondence documents, etc. Computer management is adopted in the process to improve the efficiency of document delivery and retrieval, speed up the work efficiency and better meet the requirements of the owner.
3 municipal road engineering construction process in the construction stage of quality management measures
On the elaboration and analysis of quality management measures in the construction stage of municipal road engineering, the article mainly expounds and analyzes them from five aspects. The first aspect is the survey quality control in the process of municipal road engineering construction. The second aspect is the quality control of subgrade construction in the process of municipal road engineering construction. The third aspect is the quality control of pavement construction in the process of municipal road engineering construction. The fourth aspect is the quality control of sidewalk construction in the process of municipal road engineering construction. The fifth aspect is the quality control of water supply and drainage construction in the process of municipal road engineering construction. The following will be elaborated and analyzed in detail.
3. 1 Measurement quality control in the construction process of municipal road engineering Because of the linear layout characteristics of municipal road engineering, the plane control points are usually laid with composite wires. Because of the dense buildings and structures and the complex underground pipelines, the positioning accuracy of drainage pipelines is relatively high, so the measurement accuracy should be improved to avoid the phenomenon of matching pipelines meeting and rubbing.
3.2 Quality control of subgrade construction During the construction of municipal road engineering, the excavated subgrade shall be excavated layer by layer from top to bottom according to the design requirements of slope gradient and cross section, and shall not be overbreak, disorderly excavation and under-excavation. Do a good job of drainage in time after slope excavation to prevent rain from washing the slope. It is forbidden to collapse or slope instability due to improper excavation methods. It is forbidden to dig a hole for earth or use blasting method for earthwork excavation.
3.3 Quality control of pavement construction in the process of municipal road engineering Before paving subbase and base course, the top surface of subgrade should be comprehensively inspected, and the construction of subbase and base course can only be carried out after the strength of top surface of subgrade meets the design requirements.
3.4 Quality control of sidewalk construction During the construction of municipal road engineering, the pavement should be maintained in time before it can pass. The road surface shall be smooth and stable, and there shall be no warping. There shall be no accumulated water on the pavement surface, and there shall be no exposed stones, honeycombs, cracks and peeling on the surface of precast bricks.
