Integral structure of pipe well road and municipal manhole cover
The invention discloses an integral structure of a pipe well road and a municipal manhole cover. The integral structure comprises a concrete plate, the lower surface of the concrete plate is connected with a sealing gasket, the portion, close to the upper surface, of the sealing gasket is arranged in the concrete plate in an embedded mode, and the portion, close to the lower surface of the sealing gasket is arranged in a sand-gravel cushion layer in an embedded mode; retaining wall angle steel is connected between the concrete plate and the sealing gasket and fixed on the concrete plate and the sealing gasket respectively, the bottom of the retaining wall angle steel is connected with a shaft body, the top of the shaft body is in detachably bolted connection with the retaining wall angle steel, the bottom of the shaft body penetrates through the sand-gravel cushion layer, a connecting device is arranged in the shaft body and on the lower surface of the retaining wall angle steel, and the top of the connecting device is fixed on the retaining wall angle steel. According to the integral structure of the pipe well road and the municipal manhole cover, a gap between the road and the manhole cover can be well controlled, quick drainage can be achieved, collapse can not occur, second pavement is not needed, the overall structural performance is high, and impurities can be better filtered and be convenient to clean in time.
