Building foundation pit supporting and protecting device

Abstract

The invention discloses a support device for building foundation pits. The left and right ends of the device body are fixedly connected to threaded barrels, and the upper end of a long drill rod is sleeved with a telescopic rod. The surface of the telescopic rod is evenly arranged with a plurality of first pin holes, and the left end of the telescopic rod is hinged to one level. Baffle; the upper end of the first-level baffle is slidably connected to the second-level baffle; The right end of the rod is hinged to the upper end of the support column. The device drives the support column through the threaded rod and the threaded block to stabilize the secondary baffle. The long drill rod supports the primary baffle while stabilizing the device body, and the inclination angle of the primary baffle can be changed by adjusting the length of the telescopic rod. The cooperation of the second pin hole and the second fixing pin realizes the adjustment of the height of the secondary baffle. The structural design of the device is reasonable and applicable, which greatly improves the construction safety of the construction project, and realizes the recyclable use of the support device, saving resources.

Description

technical field [0001] The invention relates to a building auxiliary device, in particular to a building foundation pit supporting device. Background technique [0002] The foundation pit support is to ensure the safety of the underground structure construction and the surrounding environment of the foundation pit, and the support, reinforcement and protection measures are adopted for the side wall of the foundation pit and the surrounding environment. [0003] The foundation pit support project is a temporary project, and the safety reserve in the design can be relatively small, but it is related to the region. Geological conditions in different regions have different characteristics. Foundation Pit Support Engineering is a discipline that intersects geotechnical engineering, structural engineering, and construction technology. It is a systematic engineering that interacts with various complex factors. The foundation pit support project has a long construction period. Fro...

AI Technical Summary

Problems solved by technology

The foundation pit support project has a long construction period. From excavation to completion of all concealed works below the ground, it often needs to experience many unfavorable conditions such as multiple rainfalls, surrounding piles, vibrations, improper construction, etc., and its safety degree is relatively random. Accidents often occur suddenly

[0004] At present, most of the existing foundation pit support methods use wooden baffles to enclose the soil slope, which has a low reuse rate and does not have a protective fence device. The support strength of the foundation pit is not enough to cause disasters such as deformation or even collapse of the baffle.
