Technical Field

[0001] The utility model relates to the field of earthwork engineering, in particular to a loose earthwork supporting device. Background Art

[0002] During the construction of earthwork projects, the internal friction and adhesion of the soil are mainly relied on to balance the downward force of the soil and maintain the stability of the soil wall. However, after excavation, the soil can easily become loose, which may lead to landslides. In order to ensure the smooth progress of the construction work, the loose soil needs to be supported.

[0003] After searching, a utility model of loose earth support device for geotechnical engineering investigation with publication number CN218757388U is disclosed, which includes a base and a flip member rotatably arranged thereon, wherein: a plurality of embedded feet are symmetrically arranged on the base, and the embedded feet are embedded in the ground surface; a soil taking window is provided on the flip member, and a plurality of fixing members are slidably arranged on both sides of the soil taking window of the flip member, and the flip member is driven to flip so that its first side surface contacts the loose earth slope surface. The utility model provides a loose earth support device for geotechnical engineering investigation, which uses embedded feet to fix the base on the ground, and then flips the flip member to contact the loose earth slope surface to cover and fix the loose earth, and a soil taking window is provided on the flip member to facilitate sampling and testing of the middle section of the slope surface of the loose earth, which can avoid the problem that the flip member covers the surface of the loose earth and cannot perform soil sampling, and sampling from the middle end of the slope surface of the loose earth can reduce the possibility of loose earth landslide.

[0004] In the existing construction excavation process, some loose earth needs to be supported, and most of the loose earth is supported by plates and crossbeams. When using plates for support, the stability is poor, and the supporting plates cannot be adjusted according to the angle and strength of the loose earth. The loose earth support device in the above comparison case lacks certain support, and can only flip the base and the flip part for support, but both lack certain support, which can easily lead to loose earth landslides and cause accidents.

[0005] Therefore, it is necessary to invent a loose earth support device to solve the above problems. Utility Model Content
