Guide structure of guide pipe and underwater concrete pouring method for raking pile and adopting guide structure

Abstract

The invention provides a guide structure of a guide pipe and an underwater concrete pouring method for a raking pile and adopting the guide structure. The guide structure comprises a plurality of plane guide plates, wherein the plane guide plates are uniformly arranged on the outer wall of the guide pipe in the axial direction of the guide pipe; connection plates are adopted to reinforce the connection between every two adjacent plane guide plates in the radial direction of the guide pipe. The axis of the guide pipe is on the plane of each plane guide plate. The guide structure is arranged at the bottom, in the middle or at the top of the guide pipe. The guide structure provided by the invention has the characteristics of simple structure, easiness in operation and high applicability. Besides, the guide structure uses less material, is low in cost, and better achieves the function of underwater batter pile concrete pouring.

Description

technical field [0001] The invention relates to a guiding structure of a conduit and an underwater concrete pouring method for inclined piles using the guiding structure, which is suitable for underwater concrete pouring construction of inclined piles in projects such as power tower foundations, docks, bridges and the like. Background technique [0002] The underwater pouring of reinforced concrete cast-in-place piles generally adopts the vertical conduit method, and the conduits are connected by screws or flanges. When the concrete of the inclined pile is poured, because the conduits are vertically lowered and lifted, the conduit joints are very easy to hang on the steel cages for reinforcement. The joints between the tendons and the main tendons can easily cause the pipes to be stuck, resulting in accidents in concrete pouring. Contents of the invention [0003] The problem to be solved by the present invention is to provide a guide structure for conduits and an underwat...
