Construction method of occlusion pile of full reinforcement pile

Abstract

An occlusion pile of a full reinforcement pile and a construction method thereof belong to the technical field of building construction. The occlusion pile formed by square reinforcement cage concrete piles and a circular reinforcement cage concrete pile which are connected in an occlusion mode and arranged at intervals is obtained through processes of construction of a guide wall, in-place of a drilling machine, down-pushing of a sleeve, soil taking and hole forming, construction of a first square reinforcement cage concrete pile, hanging of a square reinforcement cage, pouring of concrete, construction of a second square reinforcement cage concrete pile, construction of a first circular reinforcement cage concrete pile and the like. Under the condition that pile gaps are not changed, the square reinforcement cage is added in a plain pile, and polyvinyl chloride (PVC) pipes are fixed on two sides of the square reinforcement cage. A part of PVC pipes are cut off during construction of the circular reinforcement cage concrete pile, water seepage paths among piles are extended, and water seepage probability is reduced. The circular reinforcement cage concrete pile and the square reinforcement cage concrete piles resist the pressure of active soil outside a pit together after a foundation pit is excavated, steel content of a whole occlusion pile enclosure system is increased, and higher enclosure rigidity is obtained.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a construction method of an occlusal pile of an all-reinforced pile. Background technique [0002] Traditional occlusal piles are constructed in the form of one steel and one element, but for some locations that are sensitive to the deformation of the surrounding environment, such as the subway or near shallow foundation buildings, the requirements for the surrounding settlement are high, so the rigidity of the enclosure The requirements are relatively high. The traditional occlusal piles only have reinforced piles to bear the active earth pressure. The plain piles only play the role of a water-stop curtain and cannot bear the pressure. When the distance between the reinforced piles is large, it will have a greater impact on the deformation of the foundation pit; However, the smaller spacing between steel piles will lead to excessive cutting of plain pil...
