The utility model discloses a solve current super high highway section road surface and have the poor problem that influences driving safety of drainage effect, provide an excavation side slope super high highway section road surface drainage system.
The utility model discloses an adopt following technical scheme to realize: the utility model provides a side slope superelevation highway section road surface drainage system digs, including the concrete guardrail of close proximity to road bed central line, the concrete guardrail outside is provided with longitudinal drainage ditch and the inboard side ditch of superelevation with longitudinal drainage ditch parallel arrangement, be provided with the drainage ditch apron on the longitudinal drainage ditch, it has a plurality of escape canal sump pit to open along longitudinal separation in the longitudinal drainage ditch, it has the side ditch sump pit with escape canal sump pit lateral position one-to-one to open in the inboard side ditch of superelevation, and all be provided with between every pair of position corresponding escape canal sump pit and the side ditch sump pit with both intercommunications and the horizontal drain pipe of slope arrangement, horizontal drain pipe outside height is less than inboard height.
When the rainfall is great and needs to drain, a large amount of rainwater can be collected by the longitudinal drainage ditches and the drainage ditch water collecting wells, the gathered rainwater flows into the ultrahigh inner side ditch and the side ditch water collecting wells through the transverse drainage pipes, the rainwater is further collected, and when the height of the accumulated water is higher than the height of the bottom of the ultrahigh inner side ditch, the rainwater is discharged through the ultrahigh inner side ditch. The problem of current super high highway section road surface have the poor influence driving safety of drainage effect is overcome.
The drainage ditch cover plate is composed of a plurality of cover plate bodies which are longitudinally distributed, the center of each cover plate body is provided with a strip-shaped hole which is transversely arranged, the two longitudinal ends of each cover plate body are provided with semi strip-shaped holes, and reinforcing bars which are positioned around the strip-shaped holes are arranged in the cover plate bodies.
The arrangement of the drainage ditch cover plate effectively ensures that the driving safety of the road surface is ensured when rainwater is rapidly collected to the longitudinal drainage ditch.
The number of the transverse drainage pipes between each pair of drainage ditch collecting wells and each pair of side ditch collecting wells corresponding to the positions is two, and the drainage pipes are distributed up and down.
This structural design has further promoted the drainage effect.
The longitudinal drainage ditch is made of reinforced concrete, the ultrahigh inner side ditch is made of cast-in-place concrete, and the transverse drainage pipe is made of a precast concrete pipe.
The width of the longitudinal drainage ditch is 40cm, the depth is 48cm, the wall thickness is 20cm, the distance between adjacent drainage ditch water collecting wells is 100m, the width of the drainage ditch water collecting well is 40cm, the depth is 80cm, and the wall thickness is 20 cm; the diameter of the transverse drainage pipe is 50cm, and the distance from the transverse drainage pipe to the elevation of the road surface is more than or equal to 50 cm; the width of the ultrahigh inner side ditch is 50cm, and the depth is 60 cm.
The parameters are selected through a large number of repeated experiments, and the rapid discharge of medium-to-heavy rainstorms can be effectively guaranteed.
The utility model has the advantages of reasonable design reliably, effectively solved the road surface drainage problem of the excavation superelevation highway section of growing up during the heavy rainstorm for the rainwater discharges fast, avoids the problem of surface gathered water, and then guarantees current car safety, has simple structure, executes and does convenient and advantage with low costs.
