Deep foundation pit supporting device capable of draining water easily

Abstract

The invention relates to the technical field of deep foundation pit supporting, in particular to a deep foundation pit support device capable of draining water easily. The device comprises a support plate; a supporting plate is rotatably mounted at one side of the lower end of the support plate; a soil retaining net is arranged on the outer surface of one side of the support plate; a first fixingelement is mounted at one end of the upper surface of the supporting plate; a second fixing element is installed at the upper end of the outer surface of one side of the support plate; a first hinge part is welded to one side of the lower end of the support plate; a second hinge part is welded to one end of the supporting plate; an internal threaded rod is rotatably installed on the upper surfaceof the supporting plate; an external threaded rod is rotatably installed in the internal threaded rod; and a water drawing head is mounted at the lower end of the outer surface of the support plate. According to the deep foundation pit supporting device capable of draining the water easily, a water drainage structure and a support structure angle adjustable structure are arranged in the deep foundation pit support device, so that the inclination of the support device can be flexibly adjusted, and the deep foundation pit support device is provided with an independent mounting and fixing structure.

Description

technical field [0001] The invention relates to the technical field of deep foundation pit support, in particular to a deep foundation pit support device which is easy to drain. Background technique [0002] Deep foundation pit refers to a project whose excavation depth exceeds 5 meters (including 5 meters), or the depth does not exceed 5 meters, but the geological conditions, surrounding environment and underground pipelines are particularly complicated. The foundation pit project mainly includes the design of the foundation pit support system It is a highly comprehensive system engineering with construction and earthwork excavation, which requires the close cooperation of geotechnical engineering and structural engineering technicians. The foundation pit support system is a temporary structure, which is no longer needed after the underground engineering construction is completed. , The deep foundation pit supporting device is to increase the installability of the foundatio...

AI Technical Summary

Problems solved by technology

[0003] However, the deep foundation pit supporting devices currently on the market generally hinder the placement of the drainage pipe after installation, which is not conducive to the drainage inside the foundation pit. Most of the devices cannot flexibly adjust the inclination of the supporting device, making it impossible to adapt The excavation surface of the foundation pit is equipped with a slope, and most of the support is to support the corresponding side of the foundation pit at the same time. The support of the excavation surface of the foundation pit is completed through the support surfaces on both sides. It is inconvenient to install. The general device and the excavation surface The fixing method is inconvenient and the work efficiency is low
