Description

Groove supporting structure

Technical Field

Background

In the construction process of the construction site, a large number of grooves are required to be excavated on the construction site for water diversion, drainage and other works, concrete is required to be poured on the side walls and the bottom surface of the grooves after the grooves are excavated so as to keep water and soil, and the water diversion works are prevented from being influenced by flushing. Therefore, the side wall and the bottom surface of the groove meet the construction requirement of concrete pouring, and the flatness of the side wall and the bottom surface of the groove is ensured in the process of excavation; because of the special function of the groove, the groove needs to be continuously excavated and trimmed along with the continuous progress of construction progress.

In the process of trench excavation and finishing, the traditional method generally adopts manual excavation, and the manual excavation of the trench is lower in cost but lower in efficiency, and good flatness of the side wall and the bottom of the trench cannot be ensured, so that troubles are brought to subsequent concrete pouring. On this basis, in order to further improve the efficiency of the construction of slot, the job site uses the excavator to excavate the work, but because the slot is the shaping of temporarily excavating and does not tamp, the soil layer of its lateral wall is comparatively not hard up, leads to the slot lateral wall soil layer slump easily when the excavator works, influences slot lateral wall roughness, influences construction quality and efficiency. Therefore, in order to further improve the construction quality and ensure the normal operation of the excavator, a device is needed to support the trench, so that the construction of the excavator is ensured, and the good flatness of the bottom surface and the side wall of the trench is ensured.
