Construction method for pre-burying inter-pile plate steel bars of side slope

Abstract

The invention discloses a construction method for pre-burying inter-pile plate steel bars of a side slope, and belongs to the technical field of civil construction. The construction method includes the steps that drill holes are drilled horizontally on anti-slide pile guard arms of anti-slide piles with formed holes by a borer according to the positions of the inter-pile plate bars; main reinforcing bars and stirrups of the anti-slide piles are installed; the pre-buried steel bars are placed; the pre-buried steel bars are tightly sealed at the anti-slide pile guard arms through mortar; and pile body concrete is poured. According to the construction method for pre-burying the inter-pile plate steel bars of the side slope, the depth of the embedded steel bars can met the anchorage requirements, and stability and safety of the side slope can be ensured; the problem of pre-burying the inter-pile plate bars of the anti-slide piles for side slope support is well solved, and the constructionquality of the inter-pile plate steel bars is ensured; and the construction method is simple and easy to operate, good economic and social value is achieved.

Description

technical field [0001] The invention belongs to the technical field of civil construction, and in particular relates to a construction method for pre-embedding steel bars between piles on slopes. Background technique [0002] This project is located in Guiyang City, Guizhou Province, which belongs to karst landform. The construction of the project requires a large amount of excavation of the mountain. In order to reduce the amount of excavation, some positions need vertical excavation support. The mountain support of this project adopts the support method of anti-slide piles and inter-pile slab construction, that is, excavate the anti-slide piles according to the design position first, and then excavate the mountain and construct the inter-pile slabs and slab reinforcements after the anti-slide piles are constructed. The method of post-planting reinforcement anchorage is usually adopted. Due to the limitation of the distance of the mountain, it is difficult to guarantee the ...

Problems solved by technology

The mountain support of this project adopts the construction support method of anti-slide piles and inter-pile slabs, that is, excavate the anti-slide piles according to the design position first, and then excavate the mountain and construct the inter-pile slabs and reinforcements after the anti-slide piles are constructed. Usually, the method of post-planting reinforcement anchorage is adopted. Due to the limitation of the mountain distance when planting reinforcement, it is difficult to ensure the quality of the reinforcement reinforcement. Therefore, it is necessary to study the countermeasures for the anchorage of slab reinforcement between piles.

[0003] There are quality problems in the anchorage construction of the slab between piles using the conventional method of post-planting reinforcement. Because the other side of the slab between piles is close to the mountain when the reinforcement is planted, it will cause inconvenience to the reinforcement, and the depth of the reinforcement is difficult to meet the anchoring requirements. Slope stability and safety
