Construction method of ultra-long and ultra-high balance weight retaining wall in complex terrain

Abstract

The invention discloses a construction method for an ultra-long and ultra-high balance weight retaining wall under complex terrain, and belongs to the technical field of slope support construction. During the excavation process of the foundation of the retaining wall, a jumping warehouse method is adopted for construction, and the retaining wall structure adopts a horizontal jumping warehouse The construction is organized in vertical layers. The formwork is combined with steel formwork and wooden formwork, and the formwork is cable-stayed and self-balanced; The ground behind the wall is dug into reverse slope steps, and the back of the wall is backfilled after the construction of the retaining wall is completed. The invention can solve the problems of temporary side slope instability of the foundation pit during construction, difficulty in supporting the formwork of the wall body, large-volume concrete construction, water drainage of the retaining wall and difficult control of the backfill quality of the wall, etc., and has significant economic and social benefits .

Description

technical field [0001] The invention relates to the technical field of slope support construction, in particular to a construction method for an ultra-long and ultra-high counterweight retaining wall under complex terrain. Background technique [0002] With the continuous acceleration of the pace of infrastructure construction in my country, the supply of urban land resources is becoming increasingly tense. It is of great significance to alleviate the pressure of urban land supply and demand by implementing technical transformation on unfavorable terrain and geology to improve the efficiency and utilization of land planning. Mountainous cities such as Chongqing, Sichuan, Yunnan, and Guizhou often use slope protection to achieve the conversion of land resources from unusable to usable. Therefore, with the gradual scarcity of high-quality land resources, the design and construction of slope retaining structures pose higher challenges in the process of land technical transformat...
