What is included in the highway engineering quality assurance system?

Highway engineering quality assurance system: supervision, social supervision, enterprise self-inspection.

The status and role of the three links: (selection, judgment).

Supervision: Leading position, strengthen the role of supervision.

Social supervision: the core position of project management, which has a significant impact on the quality of the project.

Enterprise self-inspection: the direct producer of the product is the status of the quality former, which plays the role of the necessary conditions for achieving the three major goals and the prerequisite for the formation of the guarantee system.

Example] (1) All highway projects included in the national capital construction plan shall implement a three-component quality assurance system. （

2) The essence of project supervision is that the supervising engineer is in the core position of the project management, and uses the power of the owner to grant the child to implement comprehensive supervision of the three major objectives. (2005 exam).

3.Master the nature, basis, and task of supervision.

1) The meaning of supervision: refers to the supervision of construction activities by the competent department of construction or quality inspection department; Supervision and management of social supervision.

2) The nature of supervision: mandatory, law enforcement, comprehensive, macro.

3) ** Basis of supervision: regulations, design, standards.

4) ** Tasks of supervision: the tasks of the Ministry General Station and the provincial stations.

5) The work content of the quality inspection station. The Kuiwang Highway Supervisor Exam Channel --- divider ---

Answers]: a, b, c, d

This question examines the main provisions of the "Measures for the Management and Destruction of the Highway Construction Market". Highway engineering implements the quality fiber leakage guarantee system of first-class supervision, noisy legal person management, social supervision, and enterprise self-inspection.

Answers]: a, c, d, e

The quality assurance system of public escort wide and late road project Lu Li implements first-class supervision, legal person management, social supervision, and enterprise self-inspection.

The quality assessment and acceptance procedures of highway engineering projects are carried out sequentially according to sub-projects, sub-projects and unit projects, so the quality assessment of sub-projects involves the quality assessment of sub-projects and unit projects and whether the project can be accepted. The supervising engineer shall carefully evaluate the sub-project in accordance with the current "Construction and Installation Engineering Quality Inspection and Evaluation Standards". 1. The quality assessment of sub-projects mainly includes the following contents:

1) The guarantee project is a sub-project involving structural safety or important use performance, and they should all meet the requirements specified in the standard. The main contents included in the guarantee project are: 1) The material of important materials, finished products, semi-finished products and accessories, check the factory certificate and test data.

2) The strength, stiffness and stability of the structure and other data, check the test report. 3) During the project and after the completion of the project, it is necessary to carry out the inspection beam test, on-site spot check or check the test record. (2) inspection items Second, the use of structural requirements, use function, aesthetics, etc. have a greater impact, must be determined by sampling inspection whether it is qualified, whether to achieve excellent engineering content, it is second only to the guarantee project in the importance of sub-project quality assessment.

The main contents are: 1) It is allowed to have a certain deviation project, but it is not appropriate to accept the actual measurement project, so the data is used to stipulate the "excellent" and "qualified" standards in the inspection project. 2) For items that cannot determine the deviation value but allow certain defects, the number of defects is used to distinguish "qualified" and "excellent".

3) Adopt the method of differential treatment of different affected parts to divide "excellent" and "qualified". 4) Use the degree to distinguish the "qualified" and "excellent" of the project. 3) Measured items.

3. The project that is easy or inevitable to produce a certain deviation in the operation of each sub-project. According to the general operation level, combined with the allowable influence on the structural performance or use function, appearance, etc., a certain allowable deviation range is given. The data for the allowable deviation values are as follows:

1) Values with "positive" and "negative" requirements; 2) The deviation value has no concept of "positive" or "negative"; 3) It is required to be greater than or less than a certain value; 4) Required values within a certain range; 5) The relative proportional value is used to determine the deviation value. In China, there are detailed explanations of the standards and regulations of this kind of **. The acceptance of this part of the project is divided into sub-items and inspection batches, and the relevant acceptance is carried out in turn.

Ensure that the selection of raw materials and the quality of specific parts of the project are in line with the quality requirements of China's project.

1. Contract review management

Review the bidding documents and draft contracts to ensure that the terms of the contract are clear and well-understood and correctly understood, and review the contract before and during the execution of the formal contract.

2. Drawing data management

The whole process of the engineering and technical documents, including design changes and construction contact sheets, is controlled from issuance to control.

3. Procurement management

The company establishes a list of qualified suppliers, and regularly reviews them, formulates a complete leasing plan when purchasing products, signs a detailed contract and strictly verifies it with corresponding specifications and standards.

4. Management of materials provided by the construction unit

The materials provided by the construction unit shall be included in the procurement plan, and they shall be verified, inspected, stored and kept in accordance with the regulations, and shall be recorded and dealt with when problems occur.

5. Product identification and traceability management

Raw materials, construction processes and completed projects are effectively identified to make products recognizable and traceable.

6. Process control management

The control of all aspects of the construction process to ensure that its quality meets the requirements, and the special process is operated by qualified personnel and continuously monitored.

7. Inspection and test management

The products and processes are inspected and tested in strict accordance with the regulations to ensure that the quality meets the requirements.

8. Inspection, measurement and test equipment management

According to the regulations, the purchase, management, use, maintenance, regular verification and calibration of inspection, measurement and test equipment are strictly controlled, so that they are in good condition and the accuracy can meet the requirements of use.

9. Inspection and test status management

Operate identification and control of inspection and test status to ensure that only products that have passed the specified inspection and test and are qualified can be used and installed. There are records and physical identification.

10. Control and management of nonconforming products

Timely identification, isolation, approval and corresponding disposal measures shall be taken for raw materials, semi-finished products and nonconforming products in the process, so that they shall not be used, installed or concealed.

11. Management of corrective and preventive actions

Investigate and analyze the more serious unqualified or unqualified in the construction, take corresponding corrective measures, and regularly summarize, analyze the trend and possibility of its occurrence, and take corresponding preventive measures to reduce the unqualified to zero.
