Title:
DEEP FOUNDATION PIT RETAINING WALL STRUCTURE AND CONSTRUCTION METHOD FOR UNDERGROUND SPACE STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2021/243995
Kind Code:
A1
Abstract:
A deep foundation pit retaining wall structure, comprising a barrel-shaped retaining wall body (1), wherein a vertically penetrating water pipe (2) is cast inside the barrel-shaped retaining wall body (1), and the water pipe (2) is provided with a water outlet (3) located at the lower end face of the barrel-shaped retaining wall body (1) and a water inlet (4) located at the upper end face of the barrel-shaped retaining wall body (1). According to the deep foundation pit retaining wall structure, water can be injected, by means of the water pipe (2), into a soil body located at the lower end face of the barrel-shaped retaining wall body (1) so as to soften the soil body, thereby achieving the aim of reducing the end resistance of the barrel-shaped retaining wall body (1) so as to facilitate the sinking of the barrel-shaped retaining wall body (1); furthermore, a soil body located below the lower end face can be scoured by injecting a high-pressure water flow, so as to make the barrel-shaped retaining wall body (1) sink via gravity; and finally, the aims of reducing construction procedures, reducing construction noise, shortening the construction period and thus reducing pollution to the surrounding environment can be achieved.
