Novel energy-saving anti-floating pile

Abstract

The invention provides a novel energy-saving anti-floating pile, which comprises a cement pile body. An anti-pulling rib body, a pile tip, anchoring plates and a protective tube are embedded in the pile body, and are connected together; the anti-pulling rib body is connected with a base plate of a structure, and transmits the anti-floating force provided by the anti-floating pile to the base plate of the structure to realize the anti-floating of an underground building. Large anti-floating force can be acquired through large friction force between a large-diameter rotary-jet mixing pile body and foundation soil. The protective tube is adopted to protect the anti-pulling rib body, and the durability of the anti-pulling rib body is greatly improved; and the anti-pulling rib body is made of a high-strength material, so steel can be saved. In addition, the anti-floating rib material is connected with a plurality of anchoring plates, and the binding power between the anti-floating rib material and the rotary-jet mixing pile body is greatly increased, so that several problems of the conventional anti-floating pile are effectively solved, the construction period is effectively shortened,and the engineering cost is reduced.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to anti-floating piles for ground foundations and underground structures, and anti-floating piles for towering buildings. Background technique [0002] With the rapid development of urban construction and traffic engineering, the development and utilization of underground space has become a trend. Subsequently, the buoyancy produced by groundwater has a particularly prominent impact on underground structures, and the greater the buried depth of the underground structure, the higher the buoyancy produced by groundwater. The effect of groundwater pressure on the underground structure is mainly manifested in: basement floor uplift, basement water leakage until the floor is destroyed; the uneven floating of the whole underground building will cause cracks at the beam-column joints, floor cracking and building tilting, etc. In order to meet the needs of the force balance of th...

AI Technical Summary

Problems solved by technology

[0008] For soil anchors or anchor cables, it has the advantage of low engineering cost, but due to the unreliable durability protection of cracks in the grouting body and the imperfect construction technology, it is difficult to popularize in the field of anti-floating piles

[0009] Based on the existing problems of commonly used anti-floating piles, the engineering community urgently needs to develop a new type of anti-floating piles, which can provide sufficient anti-buoyancy and solve the problems of pile durability and service life.
