Mechanical quick-hole-formation construction method for improved simple rectangular anti-slide pile

Abstract

The invention discloses a mechanical quick-hole-formation construction method for an improved simple rectangular anti-slide pile. The method comprises the specific steps that A, a rectangular pile hole is subjected to paying-off and positioning; B, a rectangular steel pile casing is manufactured; C, a rotary digging pile machine performs hole digging according to the pile core sequence number andposition; D, a hydraulic vibration hammer is used for downwards placing the rectangular steel pile casing into the rectangular pile hole, and excess earth is removed; E, an overbreak area of the outerside of the steel pile casing is poured with concrete; F, the hydraulic vibration hammer is used for taking out the steel pile casing; G, a rectangular reinforcement cage is downwards placed and poured with concrete to form the anti-slide pile. The construction method solves the problems of slow construction progress and extremely high hole formation difficulty of a manual digging pile and has the advantages of being convenient to operate, safe to construct, high in efficiency and wide in application range.

Description

technical field [0001] The invention relates to a hole-forming construction method of an anti-slide pile, in particular to a construction method for fast mechanical hole-forming of a rectangular anti-slide pile, and belongs to the technical field of slope support structure construction. Background technique [0002] As we all know, rectangular anti-slide piles usually adopt the construction method of manual digging. The construction operation method of the manual hole-digging pile is simple, the construction is convenient, and the construction quality is easy to guarantee. However, the underground operation conditions of excavated piles are poor, the environment is harsh, the labor intensity is high, the construction speed of single piles is slow, and the safety hazards in construction are also very prominent. The construction personnel must work underground, the personal safety problem is extremely serious, there are many unsafe factors and hidden dangers, and the construc...

AI Technical Summary

Problems solved by technology

[0006] In order to overcome the deficiencies of the existing technology, the present invention provides a hole forming speed, high positioning accuracy, convenient operation, low safety risk and wide applicability, which can greatly improve the construction efficiency, speed up the construction progress, accurate positioning, and solve the problem of manual digging. The construction progress of hole piles is slow and the risk is high, so it has a good market application prospect

[0007] Another object of the present invention is to achieve low construction cost, good hole-forming quality and high precision, and solve the problem of low efficiency of manual digging piles breaking into the rock, and blasting excavation is not allowed in complex environments, making hole-forming construction extremely difficult For the big problem, it only needs to use conventional rotary excavation machinery and equipment, but it will not only increase the construction cost, but also reduce the labor intensity of the operator to the greatest extent. Such an improved simple and simple rectangular anti-slide pile mechanical rapid hole-forming construction method
