Description

Technical Field

[0001] The utility model relates to the technical field of foundation pile reinforcement, in particular to an auxiliary reinforcement structure for foundation piles in house construction. Background Technique

[0002] A foundation pile is a vertical or inclined foundation member set in the soil, and its function is to penetrate through 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. Foundation piles can be roughly divided into friction piles and end-bearing piles according to the force principle of the foundation. Friction piles use the friction between the formation and the foundation pile to bear the structure, and are suitable for situations where there is no hard bearing layer or the bearing layer is relatively deep in the formation; while end-bearing piles are to make the foundation pile sit on the bearing layer (such as on the rock mass) to bear the structure. According to the construction method, foundation piles can be divided into precast piles and cast-in-place piles. Precast piles are driven into the ground by a pile driver with precast reinforced concrete piles, which have the advantages of material saving and high strength, but the construction difficulty is relatively high, and the construction time is long due to the limitation of the number of machines. Cast-in-place piles are drilled on the construction site, and after reaching the required depth, steel bars are placed and concrete is poured.

After long-term use of highway bridges, the foundation piles are prone to looseness, and corresponding reinforcement devices are needed to effectively fix and reinforce the foundation piles.
