Groove supporting device

Abstract

The invention provides a groove supporting device, and belongs to the technical field of groove supporting. The problem that in the prior art, supporting limits construction is solved. The trench supporting device comprises a breast board used for supporting the side wall of a trench; the cross beam is transversely arranged and is used for supporting the soil retaining plate; the support is supported between the two opposite cross beams, and the length of the support is adjustable; guide grooves are formed in the cross beams in the length direction, the two ends of the support are located in the guide grooves of the two opposite cross beams respectively, support end positioning grooves communicated with the guide grooves are formed below the guide grooves, and the ends of the support can enter the positioning grooves from the guide grooves. And when the end part of the support is positioned in the positioning groove, other end parts of the support can pass through the guide groove above the positioning groove. The bracket can conveniently move along the cross beam, limitation of the bracket to construction is avoided, more stable positioning and fixing of the bracket can be achieved through the positioning grooves, the bracket sequence can be adjusted easily, and operation is simplified.

Description

technical field [0001] The invention belongs to the technical field of groove support, in particular to a groove support device. Background technique [0002] During the construction of building foundations or the laying of underground pipes and cables, trenches need to be excavated. In order to prevent the collapse of the earthwork on both sides of the trenches, the sidewalls of the trenches on each side need to be supported by earth retaining boards. The retaining plates on the side are arranged one by one along the length of the groove, and several retaining plates on each side are supported by a beam at the same time. In order to improve the supporting force, more support supports are usually required, but the existence of support supports affects the continued excavation and construction of trenches. Workers usually can only intersperse construction in the space between the support supports, which is extremely inconvenient. [0003] Therefore, how to reduce the impact ...

Problems solved by technology

[0002] During the construction of building foundations or the laying of underground pipelines and cables, trenches need to be excavated. In order to prevent the collapse of the soil on both sides of the trench, the side walls of the trench on each side need to be supported by earth retaining boards. The soil retaining boards on the side are arranged one by one along the length direction of the trench. Several soil retaining boards on each side are supported by a beam at the same time. The opposite beams on both sides of the trench are supported by braces. The length of the braces is adjustable. In order to improve the supporting force, more support is usually needed, but the existence of the support affects the continuous excavation and construction of the trench. Workers usually can only intersperse the construction in the space between the support, which is extremely inconvenient
