Processing method of anti-sliding pile buffer layer coupled with porous buffer structure and shock-absorbing protective layer

Abstract

The invention relates to anti-slide pile technology, and aims to provide a method for processing an anti-slide pile shock-absorbing layer coupling a porous shock-absorbing structure and a shock-absorbing protection layer. Including: making a porous cushioning structure with two-way regular pyramidal units with rubber materials; enclosing the pouring formwork with CFRP side plates in the pit, placing the steel skeleton and pouring concrete to make anti-sliding piles; The pits are filled with porous cushioning structures and then poured with concrete, cured and sealed according to prescribed methods. The invention can effectively absorb the energy staggeredly applied by the anti-sliding piles of the soil body, reduce back and forth shearing of the anti-sliding piles at the sliding surface, and protect against shearing. The bidirectional rectangular pyramidal porous structure based on high damping rubber material can effectively reduce the moment load on the front side of the pile, so that the actual moment load on the front side of the pile will not exceed the design load, so that the anti-slide pile will not be broken. It can play the role of uniform load and avoid damage caused by stress concentration.

Description

technical field [0001] The invention relates to anti-slide pile technology, in particular to a processing method for anti-slide pile shock-absorbing layer coupling porous shock-absorbing structure and shock-absorbing protection layer. Background technique [0002] Landslides are one of the most harmful geological disasters. my country's mountainous areas (including plateaus, hills, etc.) have a large area, accounting for about 2 / 3 of the country's total area. has a major impact. At present, anti-slide piles are one of the main engineering methods to control landslide disasters. They have large anti-slide ability, flexible pile positions and flexible construction, and play an important role in the control of large and medium-sized landslides. Anti-slide piles are usually columnar structures with a rectangular cross-section. Under general static conditions, the anti-slide piles of these structures work well and effectively reduce the occurrence of landslides. However, when hi...

Problems solved by technology

And the anti-slide pile will bear the bending moment force of the soil in front of the pile. Since the steel bars in the anti-slide pile are more on the tension side of the pile body (the back side of the pile), the number of steel bars arranged on the front side of the pile is less, or even no steel bars are arranged. , so the tensile strength of the front side of the pile is relatively weak

However, under the action of the earthquake, the front side of the anti-slide pile will also be subjected to the bending moment force of the soil. Due to the insufficient design tensile strength of this side, the side will be broken and damaged
