Novel slide-resistant pile structure superior in seismic performance and implement method thereof

Abstract

The invention relates to a novel slide-resistant pile structure superior in seismic performance and an implement method of novel slide-resistant pile structures superior in seismic performance. The novel slide-resistant pile structure is composed of a reinforced concrete slide-resistant pile body, reinforced concrete retaining walls and an EPS filling layer. The implement method of the novel slide-resistant pile structures comprises the steps that pile pits of reinforced concrete slide-resistant pile bodies are excavated one by one, the retaining wall is arranged timely when one pile pit is excavated until the pile pit is excavated to the designed elevation, pre-cast blocks of the EPS filling layers are upwards installed one by one to the elevation of the pile top from the elevation of each pile pit bottom, and reinforcement cage binding and concrete pouring and maintenance are carried out on the reinforced concrete slide-resistant pile bodies. The novel slide-resistant pile structure superior in seismic performance and the implement method of the novel slide-resistant pile structures superior in seismic performance have the advantages that the pre-cast blocks of the EPS filling layers are low in price, can be produced in a standardization mode and are convenient to assemble on site. The novel slide-resistant pile structure is an organic whole combining rigidness with softness, not only can the requirement for resisting landslide thrust be met, but also the good energy dissipation function under the earthquake working condition can be achieved, and then the seismic performance of the structure is improved.

Description

technical field [0001] The invention mainly aims at improving the anti-seismic performance of the anti-sliding pile project, and it is a structure and its implementation method, especially applicable to projects with high anti-seismic fortification intensity and areas where geological disasters occur frequently. Background technique [0002] At present, the crustal movement is active, and my country is a country with frequent geological disasters. In recent years, there have been many major earthquakes, such as Wenchuan in Sichuan (2008), Yushu in Qinghai (2010), and Ya'an in Sichuan (2013). And the Zhangxian earthquake in Minxian County, Gansu Province (2013) brought huge losses to people's lives and property. Anti-slide piles are a commonly used engineering method in the management of geological disasters. They are widely used in engineering fields such as railways, highways, and water conservancy. However, the anti-seismic problem of this rigid structure has attracted more...

AI Technical Summary

Problems solved by technology

[0011] Anti-slide pile engineering is widely used in landslide control projects. As a reinforced concrete structure, it can be adapted to resist landslide thrust due to its high rigidity. The effect is not obvious, resulting in large damage to the pile itself; and EPS material has sufficient flexibility, and has a good energy dissipation effect under the action of seismic inertial force
