Construction method of wall structure of green subgrade pile plate

Abstract

The invention relates to a construction method of a wall structure of a green subgrade pile plate. The construction method has the advantages that the stability of a green groove structure body is effectively guaranteed in the construction process of the wall structure of the green subgrade pile plate, the safety in construction is improved, and the construction efficiency is improved. The construction method comprises the following steps of digging a pile well of a reinforcing pile; installing a casting formwork of the reinforcing pile; casting the reinforcing pile; removing a concrete formwork; installing a first layer of green groove structure body on ground; arranging a fixed rod in a foundation at one side, near the building body, of the middle part of the first layer of green groovestructure body; arranging a support rod at the inner side of the fixed rod; arranging a first soil blocking plate structure between the fixed rod and the reinforcing pile; repeating the previous stepsuntil the installation of all green groove structure bodies and soil blocking plates is completed; fixing a tension rope at the top part of the fixed rod; fixing a tension rope in the middle part ofthe fixed rod; fixing the outer ends of the fixed tension ropes at the top part and middle part of the fixed rod to an anchor pull pile at the foundation outside the building body engineering; removing the support rod at the inner side of the fixed rod; filling the subgrade filling oil by layers to the design location; removing the tension ropes, and the fixed rod; filling nutritional soil into green grooves of the green groove structure body.

Description

technical field [0001] The invention relates to a construction method of a green subgrade pile-slab wall structure. Background technique [0002] The subgrade pile-slab wall is widely used in reinforcement projects. Its structure is composed of reinforced concrete reinforcement piles and retaining boards, so it is difficult to protect the structure greenly. However, with the continuous improvement of people's living standards, the environmental requirements are getting higher and higher. , especially in environmentally sensitive areas such as residential areas and scenic areas, the inventors have proposed a roadbed pile-slab wall structure with green protection functions, in which a soil retaining board and a green groove structure are arranged. The retaining slabs of traditional subgrade pile-slab walls are generally placed and fixed in blocks, and then filled in layers, and the construction is completed in this cycle. Since the width of the retaining slabs is generally 0.5...

AI Technical Summary

Problems solved by technology

The retaining slabs of traditional subgrade pile-slab walls are generally placed and fixed in blocks, and then filled in layers, and the construction is completed in this cycle. Since the width of the retaining slabs is generally 0.5m, at most every two layers of filling soil need to be installed and fixed. Soil retaining board, so the construction efficiency of subgrade filling is very low

In the structure proposed by the inventor, a greening groove structure with a small thickness and a center of gravity shifted outward is newly added. Therefore, if the traditional roadbed pile-slab wall construction method is used, the construction efficiency will be lower, and the greening groove structure will be lower during the construction process. It is not easy to fix, and is prone to instability. Therefore, it is necessary to propose a construction method suitable for green subgrade pile-slab wall structures, and has the characteristics of safe, fast, convenient and economical construction.
