Embodiment Construction

[0008] Summary of the Invention The specific implementation of the present invention has been described in detail, and will not be repeated here. It needs to be explained: 1. The main function of the anchoring steel bar 9 is to firmly tie the steel pipe pile and the pile cap 7; 2. The main function of the inflatable membrane 3 The function is to protect the high-pressure gas from leakage, so that the pressure of the high-pressure gas remains constant; 3. In order to facilitate the transportation and installation of steel pipe piles, the cylinder body 2 can be transported and welded in sections. After the cylinder body 2 is installed , then install the inflatable film 3, and finally weld the uploading force cover 1 and the cylinder body 2; four, the present invention is actually a composite pile that combines the reinforced concrete pile and the inflatable prestressed steel pipe pile together to be stressed together, if After the construction of the building is completed, it is ...

Abstract

The invention relates to a composite pile combining a reinforced concrete bored pile with a pneumatic prestressed steel pipe pile. The composite pile is mainly used as a pile foundation in the field of constructional engineering. The reinforced concrete bored pile and the pneumatic prestressed steel pipe pile are combined for bearing force together, thus the bearing capacity of the pile foundation is increased, and the tensile property of steel can be fully exerted. The composite pile is mainly composed of the pneumatic prestressed steel pipe pile, the reinforced concrete bored pile, a pile cap and anchor steel bars, wherein the steel pipe pile is mainly composed of a fore transmission cover, a drum body, a pneumatic membrane, an empty chamber and an air inlet pipe, and the reinforced concrete bored pile is mainly composed of vertical bearing force steel bars, stirrups and a pile body. The main construction method of the composite pile comprises the steps: constructing a pile hole, and then pouring concrete of the pile body; sinking the steel pipe pile and a steel bar cage together to a preset elevation, then continuing to pour the concrete of the pile body to a designed elevation, constructing the pile cap, and finally inputting high-pressure air into the air inlet pipe of the steel pipe pile. After the pressure value of the high-pressure air in the empty chamber reaches a preset value, the air inlet pipe is closed, and the pile foundation construction is completed.

Description

technical field [0001] The invention is mainly used for pile foundations in the field of construction engineering. Background technique [0002] The current steel pipe piles are poured with concrete in the steel pipe, and the steel pipe and the concrete bear the axial pressure together. Use a lot. Contents of the invention [0003] The present invention overcomes the above-mentioned defects. It is light in weight, high in bearing strength, can give full play to the tensile performance of the steel pipe and does not need concrete in the steel pipe, and has a fast construction speed. The piles are combined to bear the force together, which improves the bearing capacity of the pile foundation; the present invention is mainly composed of an inflatable prestressed steel pipe pile, a reinforced concrete pouring pile, a pile cap (7), and an anchoring steel bar (9); the steel pipe pile is mainly composed of Composed of force transmission cover (1), barrel body (2), inflatable me...
