Chapter I Project Overview
1.The water supply pipeline project of Quyansi Road in X District of Xi City is the infrastructure project of X District. Its completion will play an important role in Qujiang's economic takeoff. The blueprint of the project construction is designed by An× Planning and Design Institute, the construction unit is An× District Land Reserve Center, and the construction supervision unit is Shaanxi× Supervision Company designated by the Development Zone to supervise the whole process of the project construction.
2. The project starts from the pile number K0+000 of Yanqi No.3 Road in the west and ends at the pile number K0+79 1.5 of Xiang Yan Road in the east, with a total length of 791.5m. The pipeline position of this project is given by the Xi 'an X District Management Committee, which is located at10.5m south of the center line of Quyan No.4 Road.
Iii. The engineering pipeline adopts K9-grade T-shaped lined ductile iron pipe, and the pipe fittings are matched with ductile iron pipe fittings, and the T-shaped rubber ring has a flexible interface, and the effective length of the pipeline is 6m.
4. After the pipeline foundation is compacted, the compaction coefficient is 0.90.
Verb (abbreviation of verb) The masonry of valve well, exhaust well and mud drain well shall be constructed according to national standards S 143 and S 146. The size and practice of the well chamber shall be in accordance with the "Well Diagram of Annular Brick Water Supply Valve" of Xi Water Supply Company. The foundation and floor of the well chamber shall be constructed according to S460 (VI), and the inner wall shall be plastered with 1: 2 cement mortar and 5% waterproof agent.
6. See the national standard 0 1S20 1 for the installation of fire hydrant. Fire hydrants are installed at 1.0m along the sidewalk, and the height is adjusted with steel double-disc short pipes, which are anticorrosive inside and outside.
Seven, pipeline construction and acceptance, according to the code for construction and acceptance of water supply and drainage pipelines (GB50268-97), the test pressure is 65438+/-0.0mpa. After the pressure test, water quality inspection can be used only after passing the test.
Eight, the project duration is 50 days.
Nine, the project quality grade: qualified.
X. supply of engineering materials: the construction party will provide materials by itself. Before construction, plan the supply of engineering materials and deliver them to the construction site in advance to ensure that the construction needs are met.
XI。 Construction machinery and equipment and labor reserve: at present, our company's manpower and machinery and equipment resources reserve fully meet the requirements of engineering construction, and can be put into the project at any time to meet the needs of engineering construction.
