Rapid soil sampling system and method for constructing ultra-deep shaft foundation pit

Abstract

The present invention relates to a rapid soil sampling system and method for constructing an ultra-deep shaft foundation pit; the system includes vertical soil sampling equipment, a soil piling platform, a soil collection pit, a temporary protection frame and a soil collection box, wherein the vertical soil sampling equipment adopts a slide rail gantry crane; the temporary protection frame is connected with the ground wall of the ultra-deep shaft foundation pit through embedded anchor plates; the soil piling platform is arranged in an area that is located at the edge of the opening of the ultra-deep shaft foundation pit and formed by pouring reinforced concrete; the soil collection pit is arranged on the soil piling platform and positioned on the track path of the slide rail gantry crane,and the slide rail gantry crane is connected with the soil collection box through a sling. In order to prevent the soil collection box from collision during vertical soil sampling, the temporary protection frame is arranged around the soil collection box; the soil collection pit can temporarily store earthwork that cannot be transported out in time; in use, the gantry crane soil sampling equipmentis not limited by the depth of the on-site foundation pit, so that the soil sampling efficiency is improved, and thus the gantry crane soil sampling equipment is particularly suitable for soil sampling of the ultra-deep foundation pit with narrow sites.

Description

technical field [0001] The invention relates to the technical field of earthwork excavation construction, in particular to a rapid earth-taking system and method for ultra-deep shaft foundation pit construction applied in the construction of ring buildings with narrow construction space. Background technique [0002] At present, in the construction of ultra-deep shaft foundation pits with narrow construction space, two problems are usually faced. On the one hand, due to the narrow construction site and the extremely deep depth of the shaft, earthwork excavation is difficult and cannot be excavated according to conventional methods; on the other hand , the shaft surface is extremely small, and the earth moving vehicles cannot drive to the bottom of the foundation pit to transport earth, and normal excavation construction cannot be carried out. Therefore, need to adopt a kind of quick earth-taking system and method of ultra-deep vertical shaft foundation pit construction. Co...

Problems solved by technology

[0003] The purpose of the present invention is to provide a quick earth-taking system and method for ultra-deep shaft foundation pit construction, so as to solve the problem that construction in narrow areas in the prior art cannot be completed by grading in a conventional manner due to the narrow site, deep shaft depth, and small shaft area. The technical problems of earthwork excavation, and the technical problems that the earth-moving vehicles cannot drive to the bottom of the foundation pit to transport earthwork due to the extremely deep depth of the shaft but the extremely small area, and the technical difficulties of excavation construction
