Concrete interlocking supporting pile

Abstract

The invention provides a concrete interlocking supporting pile. The concrete interlocking supporting pile comprises a top beam structure, a supporting column pile structure and a conical head pile structure, the supporting column pile structure is a concrete square pile, a through hole is formed in the middle of the supporting column pile structure, the first side and the second side of the supporting column pile structure are provided with symmetrically-arranged first clamping grooves correspondingly, a second clamping groove and a third clamping groove which are symmetrically formed are formed in the third side and the fourth side respectively, the second clamping groove and the third clamping groove are both through grooves, a fool-proof hole is formed in the upper end of the supportingcolumn pile structure and is a blind hole, the upper end of the supporting column pile structure is connected with the top beam structure in a clamped mode through the two first clamping grooves, thesecond clamping groove and the third clamping groove communicate with the inner side of the top beam structure correspondingly, and the conical head pile structure is installed at the lower end of the supporting column pile structure. The concrete interlocking supporting pile can be prefabricated in batches in a factory, then transported to a designated construction site and rapidly assembled toform an integrated deep pit foundation protection waterproof wall, so that the construction period is shortened, the construction process is simple, the structural strength is high, and safety and reliability are achieved.

Description

technical field [0001] The invention belongs to the field of support engineering, in particular to a concrete chain support pile. Background technique [0002] As an enclosure structure of underground engineering, ground connection wall is widely used in deep foundation pit engineering. It can be used as a temporary retaining and water-stop structure, or it can replace the basement wall as a permanent underground structure. The underground continuous wall has a certain depth because it is set below the ground. The deeper the underground wall, the more affected it is by groundwater seepage. The reason is that in order to facilitate the lowering of the joints, a certain gap is left between the joints and the tank wall. When pouring after lowering the reinforcement cage, the fluid form of concrete will bypass the joints and flow to the adjacent reinforcement cage, and then pour In the next period, the newly poured concrete cannot be integrated with the concrete that flowed aro...

Problems solved by technology

[0004] Arranging multiple square piles to form a waterproof wall can greatly reduce the construction period. The upper ends of multiple square piles will be poured to form a crown beam as a whole connection. The crown beam mainly plays the following roles: 1. For individual or partial For piles with weak force, use the large force received by the crown beam to distribute to adjacent piles, so that other piles can enter the supporting work; 2. Deformation restraint, once the deformation or deformation tendency occurs, it will restrain the deformation of the top of the pile 3. Prestressing effect, due to the inevitability of deformation, forces in various directions are generated between the pile tops, and the crown beam can be used as a fulcrum for many counterforces, while the prior art generally passes the upper ends of several square piles through The steel cages are connected in series, and then the formwork is set up, and the concrete is poured. The construction period is very long, so it is necessary to propose a prefabricated crown beam structure, and at the same time, it is equipped with supporting square piles, which can be connected in series through simple operations later.
