Construction method of soil retaining board structure between adjacent anti-slide piles

Abstract

The invention discloses a construction method of a soil retaining board structure between adjacent anti-sliding piles. Firstly, the connecting ribs, reinforcing ribs and U-shaped ribs are anchored together with the wall protection concrete; The pile reinforcement cages are tied together; the soil between the piles is excavated in sections and excavated into an arc structure, the back side curved longitudinal reinforcement and the connecting reinforcement are bound together, and the front longitudinal reinforcement of the pile is reinforced with the L-shaped The tendons and connecting bars are bound together, and the back side bending longitudinal bars and the front longitudinal bars of the pile are bound together by connecting stirrups; the formwork is fixed and cement mortar is poured; the formwork is removed after the cement mortar is solidified; Construction work of retaining plate structure between piles for anti-slide piles. The invention makes full use of the retaining wall, avoids waste of the retaining wall, improves the soil retaining ability of the earth retaining board, further reduces the thickness of the earth retaining board, and saves construction costs; The traditional bending member is changed into a bending member, which improves the safety.

Description

technical field [0001] The invention relates to the field of slope reinforcement, in particular to a construction method for a retaining plate structure between adjacent anti-slide piles. Background technique [0002] In our country, with the development of the national economy, especially the implementation of the western development policy, the infrastructure construction of water conservancy projects, railways, highways and cities is in the ascendant, and many slope projects have appeared in these projects, such as the high slope of the Three Gorges, etc. . At present, for large-scale landslides in slope engineering, landslides with large sliding force or landslides with deep sliding surfaces, anti-slide piles are often used for support in the engineering. [0003] In the anti-slide pile construction, it is often necessary to excavate the soil in front of the pile in the cantilever section after the anti-slide pile construction is completed. In order to avoid soil colla...

AI Technical Summary

Problems solved by technology

The existing construction methods for the retaining panels between piles of adjacent anti-slide piles mainly include two construction methods: removing the anti-sliding pile retaining wall and not removing the anti-sliding pile retaining wall. It is hinged together with the retaining wall, but there is a problem that the reserved hole of the retaining board does not correspond to the pre-embedded steel bars in the retaining wall during construction, which affects the construction; the retaining board is hinged with the retaining wall, and the retaining wall cannot improve the soil retaining capacity of the retaining board, so The thickness of the retaining board is often thick and the weight is heavy, resulting in a large amount of concrete and increasing the construction cost

[0004] The existing construction method for dismantling the retaining wall of the anti-slide pile is to remove the retaining wall of the anti-slide pile first, and then construct the retaining board. The installation of isolation facilities between sliding piles still has the problem of not being able to completely isolate the cement mud, and the reinforced concrete at the corner of the retaining wall needs to be removed, which not only causes waste in engineering, but also increases the difficulty of construction
