1 application of information construction in quality supervision of construction projects
The informatization construction of construction engineering quality supervision is based on the comprehensive system of construction engineering quality supervision and management, which is composed of construction engineering quality supervision and management system, concrete tracking dynamic platform and engineering quality inspection and supervision platform, so as to realize the closed-loop management of construction engineering quality supervision with modularization, standardization and informatization. The system takes the project as the carrier, integrates the quality management systems of the construction unit, the construction unit and the supervision unit with the concrete tracking dynamic platform and the construction project quality inspection and supervision platform, and controls and tracks the project quality in time.
(1) Construction engineering quality supervision and management system. First, taking the quality supervision process as the main line, the supervision platform is composed of the quality supervision department's construction project quality supervision and acceptance, quality supervision scheme, quality supervision and inspection records, unqualified inspection reports of commonly used raw materials and components, main branch project quality acceptance supervision, completion acceptance supervision, supervision report, completion acceptance filing, project filing, project inspection and evaluation, complaints, quality problem rectification, administrative punishment of responsible subjects, bad behavior records, enforcement and management of mandatory provisions, and remote data transmission. Second, the parties involved in project activities (mainly the construction unit, supervision unit, construction unit, etc.). ) from the supervision project, supervision planning, supervision implementation details, construction plan, supervision data and construction data and other related information; The third is to collect the implementation data of concrete quality tracking dynamic supervision system and construction engineering quality inspection supervision platform.
(2) The concrete quality tracking and dynamic supervision system is to install a "black box" in the tower of a concrete production enterprise, and use the "black box" and wireless transmission technology to realize the real-time uploading of the ready-mixed concrete mixture ratio. The real-time collection system for concrete production adopts "black box" and wireless transmission technology, and directly collects the feeding data without reforming the "industrial computer" of the concrete mixing station. When the actual feeding data deviates from the design mixture ratio, especially when the cement dosage is lower than the minimum cement dosage limit of each grade of concrete, it will automatically alarm.
(3) On the basis of construction engineering quality inspection and supervision, a construction engineering quality inspection and supervision platform is established to ensure the authenticity of inspection data. By using the Internet of Things and two-dimensional code technology, witnesses attach two-dimensional code marks to the sampling samples when sampling construction materials or components, and bind witness-related information through smart phone terminals, so that the sampling process can be located and photographed by GPS, and the sample information can be recorded to form a unique logo of the samples; When collecting samples, testing institutions read and check the information in the process of sampling and transportation through the testing supervision information system, and track the whole process of witness inspection to ensure the authenticity of the samples. The QR code sticker has the functions of firm paste, waterproof, tear-proof, copy-proof and reuse-proof. The management of sample identification and circulation tracking has been well strengthened, and the problems of sample and incoming materials, sample replacement and so on have been solved to some extent. The online supervision of engineering quality inspection data and reports is realized by using the internet network data exchange platform, and the inspection status of inspection institutions is known in real time, thus ensuring the authenticity of inspection data. The platform uses the Internet of Things and two-dimensional code technology to track the whole process of witness delivery and ensure the authenticity of the test samples. Using the Internet network data exchange platform, the online supervision of engineering quality inspection data and reports can be realized, and the inspection status of inspection institutions can be known in real time.
2. Assumption of informatization of construction project quality supervision
(1) Set up a specialized agency or department to study the policies and means of quality supervision of construction projects under the unified leadership of the construction administrative director, coordinate relevant departments, and vigorously promote the informatization process of quality supervision of construction projects.
(2) In concrete quality management, "black box" and wireless transmission technology are adopted to realize real-time collection and uploading of mixing and feeding data, so as to ensure the authenticity of batching information; In the quality supervision of construction projects, information technologies such as two-dimensional code and RFID electronic chip are used to ensure the authenticity, traceability and chain and closed-loop management of building materials samples.
(3) With regard to the hardware guarantee of the information system, a professional telecom room is selected for server hosting, so as to prevent the normal and stable use of the system from being affected due to temporary power failure, network disconnection, humidity and other reasons, thus affecting the information popularization; Choose a professional and powerful application software developer to develop the system, so as to avoid the problems of low software service level and low technical level.
