Description

Technical Field

[0001] The utility model relates to the field of road construction safety protection, in particular to a safety protection device for road foundation pit construction. Background Art

[0002] One of the more common situations in road construction is digging foundation pits and laying pipelines. When such construction is carried out, the retaining structures and groundwater control and environmental protection measures required to ensure the safety and stability of the underground space formed by the ground excavation during the construction of the underground structure are called foundation pit projects. During the construction of the foundation pit, baffles are needed for on-site protection. In the existing operation, baffles are set on both sides of the foundation pit, and the baffles are fixed by support rods. The problems with the existing baffles are: (1) The ends of the support rods can only be fixed in the middle of the two edges of the baffles, and the position of the connection and fixed support cannot be adjusted longitudinally at the edges. The support rods may block the construction space; (2) The existing baffles for foundation pit construction are usually square plates. When the foundation pit reaches a certain depth, the baffles need to overlap longitudinally. However, the existing baffles are usually square plates, which are not convenient for longitudinal overlapping, and the stability after overlapping is biased; (3) Water will accumulate at any time during construction in the foundation pit. When water accumulates, it needs to be pumped out. The existing method is to pump it out through a water pump, but the water pump is directly placed in the pit during the existing construction process. Such an arrangement affects the convenience of construction. Utility Model Content
