Secant pile structure with reinforcing function and construction method thereof

Abstract

The invention provides a secant pile structure with a reinforcing function and a construction method thereof. The secant pile structure comprises first secant piles and second secant piles, wherein the plurality of first secant piles and the plurality of second secant piles are alternately engaged and connected to form a secant pile; a crown beam is arranged at the upper part of the secant pile, reinforcement cage stirrups are annularly arranged in the first secant piles, and reinforcement cage longitudinal reinforcements are longitudinally arranged perpendicular to the reinforcement cage stirrups; and grouting pipes are further longitudinally arranged in the first secant piles and used for grouting and repairing leakage into the secant pile. The secant pile structure has the beneficial effects that the secant pile structure is simple, the stress is scientific and reasonable, the construction is convenient, the construction cost is low, the construction period is not increased, and the construction quality is safe and reliable. Through a local uniform reinforcement distribution mode, the distance between longitudinal stress ribs of a reinforcement cage is adjusted, so that the reinforcement of the secant pile is more reasonable and more conforms to the stress characteristics, and the problem of foundation pit leakage caused by insufficient occlusion width of the secant pile due to the design reason, construction process or improper operation of the secant pile is solved.

Description

technical field [0001] The invention belongs to the field of construction engineering, and in particular relates to an occlusal pile structure with a reinforcing function and a construction method thereof. Background technique [0002] With the implementation of the national urbanization development strategy, the urban land is becoming more and more tense, and the development of underground space is constantly increasing. The deep foundation pit support provides a safe and reliable construction environment for the development of underground space. There are pebbles (gravel) and construction waste underground in some cities, most of which use underground continuous walls or occlusal piles. Due to improper construction technology, design or operation of occlusal piles, it is easy to cause insufficient occlusal width of the pile body, resulting in leakage of the foundation pit enclosure structure , bring construction inconvenience to the construction, and even major safety haza...

AI Technical Summary

Problems solved by technology

There are pebbles (gravel) and construction waste underground in some cities, most of which use underground continuous walls or occlusal piles. Due to improper construction technology, design or operation of occlusal piles, it is easy to cause insufficient occlusal width of the pile body, resulting in leakage of the foundation pit enclosure structure , bring construction inconvenience to construction, and even major safety hazards

At present, how many projects are remedial when hidden dangers are discovered by drilling and grouting outside the pit, which is an emergency measure after the event and will bring many adverse effects to underground space construction
