The steel plate laid by the conventional method has great influence on traveling, road blockage is easily caused by vehicle deceleration, and the steel plate is extremely unsafe when passing through a bicycle and an electric vehicle, so that potential safety hazards exist.
Therefore, it is necessary to provide a road trench excavation protective steel plate structure that can maximally reduce the influence on pedestrian traffic to solve the above problems.
Disclosure of Invention
To the above-mentioned defect that exists among the prior art, the utility model provides a can slow down road slot excavation protective steel plate structure of construction steel sheet by passway to pedestrian's driving influence.
The utility model discloses a realize through following technical scheme: the utility model provides a road trench excavation protective steel plate structure, includes the excavation slot, lays the protective steel plate in excavation slot top, characterized by: correspond on road surface the position of protection steel sheet is provided with the pit, the protection steel sheet is located in the pit have many I-steel along the vertical interval arrangement who digs the slot in the pit, the I-steel is striden and is established on digging slot upper portion, I-steel recess has been excavated respectively to the both sides of digging the slot in the pit, the both ends of I-steel set up respectively the I-steel ditch inslot, the protection steel sheet is laid on I-steel upper portion, the protection steel sheet with the rubber pad has been laid between the I-steel, the upper surface and the road surface parallel and level of protection steel sheet.
The utility model discloses a protection steel sheet is laid to the method of sinking, and the protection steel sheet is located the pit, and protection steel sheet lays back and former road surface parallel and level, and the pedestrian drives a vehicle unaffected. The I-shaped steel arranged in the concave pits can reliably support the protective steel plate. After the construction at night is finished, I-shaped steel is laid above the groove, and a rubber pad and a protective steel plate are laid above the I-shaped steel, so that the traffic can be recovered. And during the construction, the protective steel plate, the rubber pad and the I-shaped steel are dismantled.
Further, in order to guarantee reliable support of the protective steel plate, the arrangement distance of the I-shaped steel is 0.5m.
Further, for skid resistance, the surface of the protective steel plate is coated with skid-proof paint.
Further, in order to ensure the stability of the protective structure, the I-steel groove is arranged in the water stable layer of the road.
The utility model has the advantages that: the structure of the utility model adopts a sinking method to lay the protective steel plate, the protective steel plate is parallel and level with the road surface of the original road after being laid, the pedestrian can not be influenced, the pedestrian can keep running normally, the pedestrian can not pass through the protective steel plate by deceleration, the traffic jam is not easy to be caused, and the problems of traffic jam, pedestrian traffic safety accident and the like caused by laying the steel plate on the traffic trunk road due to construction are solved; the I-shaped steel is arranged on the lower portion of the protective steel plate to support the protective steel plate, and road surface passing safety is guaranteed. The utility model discloses but furthest reduces the steel sheet and lays the influence that causes the pedestrian driving, but wide application in municipal works construction.
