Approved Department: Ministry of Urban and Rural Construction and Environmental Protection Date of implementation: July 1, 1986
(85) Chengchengzi No. 545
According to the arrangement of the former State Administration of Urban Construction, the "Standard for Inspection and Evaluation of Municipal Engineering Quality (Urban Flood Control Engineering)" was compiled by the former Municipal Public Utilities Bureau of our Ministry, Wuhan Flood Control Headquarters, Taiyuan Flood Control Headquarters and other ten units. After review by our Ministry, it was approved as a departmental standard and implemented from July 1, 1986, with the number CJJ9-85. During the implementation process, if there are any questions or comments, please inform the management unit of this standard, Wuhan Flood Control Headquarters, for revision and reference.

Article 1.b.1
Chapter I General Provisions
This standard is applicable to municipal engineering newly built, expanded, and rebuilt under normal geological conditions. Municipal engineering with special requirements (such as collapsible soil areas, permafrost areas, etc.) shall still be implemented in accordance with this standard except for special requirements. Maintenance engineering in municipal engineering can refer to this standard for implementation. Relevant engineering within industrial plant areas, and relevant engineering in remote suburbs and counties (banners) outside the urban area of cities can refer to this standard for implementation. Article 1.D.2 The quality assessment of municipal engineering is divided into two levels: "qualified" and "excellent".
Article 1.D.3 Division of urban flood control engineering process, location, unit engineering: 1. Process
Divided into: earthwork, stonework, masonry, formwork, steel bar, concrete and reinforced concrete, prestressed concrete, expansion joint, settlement joint and water stop structure, plastering, pile, board, pile, cast pile, caisson, pipe, step, steel sheet pile, steel gate, hoist installation, steel step, wooden pile, wooden board pile, wooden gate, sinking row, sinking tree, sinking cage, submerged dam, riprap, anti-seepage grouting, blanket and seepage interception, dike (dam) excavation and treatment, pressure relief well, turf planting, wave-breaking forest, dike protection forest, other projects, etc.
2. LocationwwW.bzxz.Net
It should be divided according to the main parts. For projects that are generally not suitable for location division, it can also be divided into several parts according to length.
3. Unit Project
The independent accounting project in the urban flood control project should be a unit project. The same urban flood control project that adopts phased independent accounting should be several unit projects. Article 1.D. 4 In each section of this standard, the text description part should be the appearance inspection project for inspection and evaluation. Only after passing the inspection can the inspection of the items with allowable deviation be carried out.
Article 10.5 When implementing the inspection sampling of this standard, efforts should be made to make the sampling points reflect the actual situation of the project. (Where the inspection range is length, it means sampling at the specified interval, and other random sampling within the specified range). Article 1.D.6 The inspection and evaluation of the quality of municipal engineering should be carried out at three levels: process, location, and unit project. The evaluation standards are as follows: 1. Process
Qualified: Those who meet the following requirements should be evaluated as qualified 1. The qualified rate of the main inspection items (those with ^ in the project column) should reach 100%.
Qualified rate = the number of points (groups) in the grid of the second inspection item The number of points (groups) to be inspected in the same inspection item 2. The qualified rate of other inspection items should reach 70%, and the maximum deviation of the points that do not meet the requirements of this standard should be within 1.5 times the allowable deviation. Excellent: Those who meet the following requirements should be rated as excellent. 1. Meet the conditions of qualified standards.
2. The average qualified rate of all inspection items should reach 85%. 2. Parts
Qualified: If all processes are qualified, the part should be rated as qualified. Excellent: On the basis of qualified assessment, if the average qualified rate of all process inspection items reaches 85%, the part should be rated as excellent. When assessing parts. The template process does not participate in the assessment: the finished products or semi-finished products made by the prefabrication plant (processing plant) do not participate in the assessment. 3. Unit project
Qualified: If all parts and processes are qualified, the unit project should be rated as qualified. Excellent: On the basis of being evaluated as qualified, if the average qualified rate of all parts and process inspection items reaches 85%, the unit project shall be evaluated as excellent. Article 1D.7 If the quality of the process does not meet the requirements of this standard, it shall be handled in a timely manner. The quality level of the reworked project shall be re-evaluated.

Projects that change the structural appearance or cause historical defects shall not be rated as excellent. Article 1.8 The quality of raw materials required for municipal engineering, such as sand, stone, asphalt, wood, steel, cement, lime, pipes, equipment and paint, must meet national standards or standards of relevant ministries and bureaus.
Article 1.D.9 The quality inspection and assessment of municipal engineering projects must be based on the self-inspection and mutual inspection of the construction team, and full-time (or part-time) inspection personnel must participate before the process handover inspection can be carried out, the process grade can be assessed and Table 1.0.9-1 can be filled in; the part handover inspection must be carried out on the basis of the process handover inspection, and the part grade can be assessed with the participation of full-time personnel and personnel appointed by the superior, and Table 1.0.9-2 can be filled in; the unit project handover inspection must be carried out on the basis of the part and process handover inspection, and the superior organization of relevant personnel should conduct the inspection, assess the unit project quality grade and fill in Table 1.0.9-3. Article 1.D.D When the unit project is completed and the handover inspection is carried out, the completion drawing technical data; engineering material qualification certificate; on-site observation record; test result report: as well as hidden project inspection report and construction record, etc. must be attached as an important basis for quality inspection.
