Description

Technical Field

[0001] The utility model relates to the technical field of pile foundations, in particular to a group pile foundation connection structure. Background Art

[0002] When constructing a pile group foundation, the piles are fixed symmetrically from the middle of the pit foundation to the surrounding sides, so that the piles are arranged in order in the pit foundation. During the placement of the piles, the soil around the piles will be squeezed to the surrounding sides, thereby making the piles on the surrounding sides and the pit foundation more firmly connected.

[0003] However, as the soil is continuously squeezed, each time a pile is inserted, the soil on the surrounding side will be squeezed outward, causing the pile body on the surrounding side to be slowly pushed by the soil, which will cause the pile body to shift, thereby affecting the overall quality of the pile group foundation.

[0010] Furthermore, the fixing bolts are arranged on the fixing ring in a staggered manner.

[0011] Compared with the above background technology, the pile group foundation connection structure provided by the present application includes a pile group foundation with very mature technology today, and a connection mechanism as a core component. The principle relies on the mutual matching between the rotating support member that can rotate at an angle and the connecting hoop member that is stably connected to the pile body to achieve stable support between the pile bodies.

[0012] The utility model provides a pile group foundation connection structure. Compared with the prior art, it has the following beneficial effects:
