Description

Technical Field

[0001] The present application relates to the technical field of pile foundations, and in particular to a water conservancy engineering pile foundation. Background Art

[0002] Water conservancy projects refer to various projects built to control, regulate and utilize natural surface water and groundwater in order to achieve the purpose of eliminating harm and promoting benefits. Water conservancy projects can be divided into flood control projects (dikes, reservoirs, flood storage and diversion areas, culverts, drainage projects, etc.), farmland water conservancy projects (irrigation projects), hydropower projects, shipping and urban water supply and drainage projects according to their service objects. Pile foundations are needed in water conservancy projects. Pile foundations are a deep foundation that connects the tops of several piles into a whole through a pedestal to jointly bear dynamic and static loads. A pile is a vertical or inclined foundation component set in the soil. Its function is to penetrate soft, highly compressible soil layers or water and transfer the load borne by the pile to a harder, denser or less compressible foundation bearing layer. Each pile is made by pouring concrete after the steel cage is primed.

[0003] However, traditional steel cages are mostly cylindrical structures. The following problems were found during the actual on-site construction process: when the steel cage is placed during the construction process and inserted into the ground pile, the support stability between the bottom area of ​​the steel cage and the bottom of the ground pile is poor, and the steel cage is generally long, so it is easy to tilt during the support process of the steel cage, which affects the subsequent pouring of concrete. Therefore, we proposed a water conservancy engineering pile foundation to solve the above problems. Utility Model Content

[0010] The supporting mechanism includes a slide cylinder, which is slidably connected to the lifting column. A fixing rod is rotatably installed on the outer wall of the slide cylinder, and the fixing rod passes through the outer wall of the steel cage. Two limit plates are rotatably installed on the outer wall of the lifting column. The outer wall of each limit plate is fixedly connected to the outer wall of the lifting column through a spring, and the outer wall of the limit plate is in contact with the inner wall of the slide cylinder.

[0016] Furthermore, a fixing seat is fixedly mounted on the outer side wall of the lifting column, and the fixing seat is fitted with the top end of the sliding cylinder.

[0017] (III) Beneficial effects

[0018] Compared with the prior art, the present application provides a water conservancy engineering pile foundation, which has the following beneficial effects:
