The beneficial effect of this scheme is: compared with the existing running way provided with the rain water inlet, the sinking design of the facility belt enables the water flow of the facility belt to be larger than that of the rain water inlet, so that the number of the rain water wells is obviously reduced, and the construction cost is reduced.
Further, one side of the traffic lane close to the facility belt is provided with a plurality of anti-collision guardrails, and the anti-collision guardrails are arranged at intervals along the length direction of the traffic lane.
The beneficial effect of this scheme is: due to the arrangement of the anti-collision guardrail, the vehicle can be prevented from driving into the facility belt to cause safety accidents and damage to the facility belt; because the anti-collision guardrails are arranged at intervals along the length direction of the traffic lane, the water flow on the traffic lane can be ensured to smoothly flow to the facility belt.
Further, the height of the crash barrier is 30-32cm.
The beneficial effect of this scheme is: the height of the anti-collision guardrail is set to be 30-32cm, so that the aims of calibrating the range of a traffic lane, guiding the vehicle to run and preventing the vehicle from running on the pavement can be achieved; on the other hand, the appearance is not affected because of the over-high anti-collision guardrail.
Further, the depth of the facility belt is 13-15cm.
The beneficial effect of this scheme is: the depth of the facility belt is 13-15cm, so that the shallow butterfly-shaped ditch is shallow, the ditch bottom ditch wall is gentle, and pedestrians cannot fall into the butterfly-shaped ditch to threaten personal safety of the pedestrians.
Further, the facility belt is sequentially paved with a first surface layer, a waterproof layer and a soil base layer from top to bottom.
The beneficial effect of this scheme is: if the facility belt is not provided with a waterproof layer, water in the facility belt can enter the soil base layer to cause uneven settlement of the soil base layer, so that the facility belt is sunk and deformed, the service life of the facility belt is shortened, and the waterproof layer is arranged, so that the problem can be avoided.
Further, the second surface layer is paved on the upper surface of the pavement, and paving materials of the first surface layer are consistent with those of the second surface layer.
The beneficial effect of this scheme is: because the paving material of the first surface layer is consistent with that of the second surface layer, the pavement and the facility belt are connected into a whole, and the bottom ditch wall of the shallow butterfly ditch of the facility belt is gentle and can be used for walking of pedestrians.
Further, the bottom of facility area is equipped with the spread groove of a plurality of slopes, and spread groove and connecting pipe one-to-one, the upper end and the spread groove intercommunication of connecting pipe, and the upper end of connecting pipe is less than the first surface course on spread groove right side.
The beneficial effect of this scheme is: because the upper end of connecting pipe is less than the first surface course on spread groove right side for the first surface course on spread groove right side has formed a retaining wall on the right side of connecting pipe, makes the rivers in the facility area gather in the spread groove department, when the connecting pipe is in full flow state, has increased the rivers extrusion force of connecting pipe upper end, makes rivers can flow to in the catch basin faster, has improved the drainage rate of facility rainwater.
