Qishuyan sewage treatment plant phase III project since September last year, entering the construction so far, has now completed the micropore aeration oxidation ditch, V type filter, chlorine contact tank (pool below) and the secondary clarifier of 1# 2#, with wells, sand sedimentation pool, phosphorus pool, concentration tank, storage tank, power distribution room, the center of the motor, machine repair shop, sludge hopper, such as the main body of the object construction monomer structure, and has been with the conditions of acceptance subject.
September 18th Qishuyan sewage treatment plant in the three phase of the main project acceptance, Party A, supervision, survey, design, municipal quality supervision station are present.
In the entire construction process, the project department is equipped with a strong personnel, actively cooperate with the supervision, construction units to strictly control the relevant approach materials, strict supervision of construction technology, so that each sub project to reach the design and construction specification requirements.
1, template engineering: in order to ensure the accuracy of geometric size and relative position of the concrete structure, the template of each part of the size must be consistent with the design. The template and scaffold, must have sufficient strength, stiffness and stability. Prior to construction, the design drawings must be refined, and the location, type and quantity of the template are indicated, and the template is made according to the structure form, the size and the concrete pouring method. Strengthen management, reasonable operation, maintain the integrity of the template, to ensure the quality of the project.
2, steel engineering acceptance: (1) the design and construction requirements, according to the design and construction requirements, according to the wall thickness and reinforced concrete, specifications, accurately grasp the different design earthquake level and different concrete strength level, the anchorage length and the length of the reinforced concrete, accord with the design and related specifications. (2) the reinforced material table must be passed through the bar to check the back of the material processing. (3) the position of the reinforced joint, the length of the overlap, the length of the reinforcement, the diameter of the reinforcement, the thickness of the protective layer shall be strictly in accordance with the design drawing. (4) the acceptance of steel to the specifications, quantity, location, shape, joint type, location, size, number, location, specifications, etc., after the inspection and then reported to the supervision, Party A, design the relevant personnel to carry out concealed inspection, in accordance with the design drawings and relevant specifications, signed a concealed project after pouring concrete.
3, concrete engineering: this project concrete uses commodity concrete, in order to guarantee the structural entity strength, the safety and the use project, I project department to the construction each stage all earnestly carries on the quality control. (1) slump. Commodity concrete to enter the site, in pouring site measured slump must conform to match ratio design requirements; (2) intensity. The strength of the main body structure, foundation, wall, beam, column, plate and so on, must comply with the design requirements and specifications. (3) axis. Control engineering plane position correctly, to ensure the wall column plane position, and the upper and lower vertical and uniform. (4) elevation. To control the position of the engineering elevation, to ensure that the height of the floor structure, to ensure the use of space and the correct. (5) founder. Ensure that the geometry of the space and the components, making the error within the allowable range. (6) formation. Including flat and vertical flat surface, as well as the requirements of the slope, curvature, line, etc..
4, masonry engineering
This project uses concrete block wall, masonry mortar is M5.0, M7.5 ready mixed mortar. Prior to the construction of the material plan by the project department, material for the selection of qualified suppliers and timely arrangements for the material approach, to ensure the quality of block material. Wall masonry for team leaders and staff must conduct technical tests by the technician, to prevent the wrong and ensure the construction quality of masonry rework.
All the projects of this project have been qualified for acceptance, and the hidden records are complete. Engineering quality control information is basically complete, engineering safety and functional testing report is basically complete, no accidents, the use of commercial concrete, the use of cement, sand, stone, fly ash, admixture and other raw materials, the company's self inspection, quality assurance data is complete, according to the standard sample strength to meet the design requirements.
The main part of the design and the quality of the national construction quality has reached the design and acceptance of national construction quality standards, the quality of the test, the quality supervision station, Jia Fang, supervision, survey, design site inspection and acceptance, Qishuyan sewage treatment plant in the three phase of the main project acceptance.
