Abstract

The invention belongs to the technical field of road construction, and particularly relates to a foundation pit support device for road construction. Based on the problems that most traditional foundation pit support devices are simple in structure and common in support effect, the following scheme is proposed: the foundation pit support device comprises a mounting base; a main box body is fixed to the outer wall of the top of the mounting base through bolts; a material opening is formed in one side of the main box body; a servo motor is fixed to the outer wall of the top of the main box bodythrough bolts; and an output shaft of the servo motor is connected with a rotating column through a coupler and the rotating column is rotationally connected with the main box body. The warning effectof the device at night can be effectively improved, and the warning and protection effects of the device are improved; through the arrangement of a rocker, a threaded rod can be driven to rotate, andunder the limiting effect of a limiting sliding groove and a sliding block, a moving block is driven to effectively fix the device through a needle inserting rod; and inverted fork thorn rods distributed at equal intervals are arranged on the needle inserting rod, so that the fixing effect of a tube can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to a foundation pit enclosure protection device for road construction. Background technique [0002] The tasks of new construction or reconstruction of highways are determined according to the road network planning. The road construction of a country should comprehensively consider its role and status in combined transportation in combination with railway, waterway, air and other transportation, and formulate a national road system divided into grades according to its political, military, economic, and people's life needs, combined with geographical and environmental conditions. Road network planning. In terms of administrative division, it is generally divided into four levels: national roads, provincial roads, county roads, and township roads. In the process of road construction or maintenance, especially for the construction site of foundation pit, because it often ha...
