Embodiment Construction
[0031] In conjunction with the description of the accompanying drawings, the specific embodiments of the present invention are further described:
[0032] refer to Figure 1-Figure 6 , the present invention provides a kind of water intake pipe fixing construction method, construction steps are as follows:
[0033] S1: The construction platform on the ship is built; the ship is anchored and fixed, and a temporary construction platform is set up on the ship, which overcomes the problem of providing a construction surface in a complex environment. Secondly, the construction speed of the river surface construction platform is fast, and has little impact on the river water and surrounding environment, which is conducive to the success of subsequent projects. carry out guarantees;
[0034] S2: Piling steel pipe piles; the outer casing is buried, drilled, and the inner casing is installed. The length of the casing is the full length of the pile. The inner casing is equipped with a s...

The invention belongs to the technical field of water intake pipeline support piers, and in particular relates to a construction method for fixing a water intake pipeline, which solves the problems of complicated techniques, slow construction speed and serious river water pollution in the traditional construction method. The construction steps of the present invention are as follows: S1: the construction platform on board is built; S2: steel pipe piles are driven; the outer casing is buried, drilled, the inner casing is installed, and the steel cage in the inner casing is poured with concrete; S3: the fixing device is installed; The steel pipe pile is fitted with a hoop bracket, and the boat-shaped steel pier box is set outside the steel pipe pile and lowered to the top of the hoop bracket, the position of the boat-shaped steel pier box is finely adjusted, welded, fixed, and sealed; S4: Water intake pipeline installation; water intake pipeline Lower it into the U-shaped groove of the boat-shaped steel pier box, plug and seal it; S5: pour concrete into the boat-shaped steel pier box; S6: pour the pipeline foundation outside the boat-shaped steel pier box. The invention has the advantages of simple operation, accelerated construction progress, shortened construction period, high production efficiency, guaranteed construction quality, and reduced construction pollution to water sources.
Description
technical field [0001] The invention belongs to the technical field of water intake pipeline support piers, and in particular relates to a construction method for fixing a water intake pipeline. Background technique [0002] It is imperative to relocate the intake of urban waterworks. Large-scale water intake pipes are all set in the river, the water flow is unpredictable, and the underwater terrain is complicated. The traditional construction method is to create a construction area in the river cofferdam, drain the water in the construction area of the cofferdam, and carry out the construction in the construction area. The reinforcement construction of the water intake pipe, the traditional construction method is complicated, the construction speed is slow, and the river water is seriously polluted. Contents of the invention [0003] The present invention solves the problems of traditional construction methods such as complex process, slow construction speed and seriou...
