Description

Technical Field

[0001] The invention relates to the field of roadbed engineering construction, and in particular to a roadbed single-side water collection well and cross well drainage system. Background Art

[0002] With the continuous development of my country's expressways, environmental sensitive factors in roadbed construction have imposed more and more restrictions on road construction. The roadbed of this project belongs to the embankment road of the Beijing-Hangzhou Grand Canal. The water source of the Beijing-Hangzhou Grand Canal is developed for fishery breeding industry. After rainfall on the road surface, it is polluted by passing vehicles and the water quality does not meet the standards required by fisheries. Therefore, it needs to enter the sewage treatment plant on the other side for purification before discharge. Therefore, it is necessary to design a drainage system that can divert water to the other side of the roadbed. Summary of the invention

[0003] The object of the present invention is to provide a roadbed single-side water collection well and cross-well drainage system to solve the above-mentioned problems.

[0004] In order to achieve the above-mentioned purpose of the present invention, the following technical scheme is adopted:

[0005] A roadbed single-sided water collection well and cross well drainage system, a fishery breeding river is arranged on one side of the road surface, a residential area drainage ditch is arranged on the other side of the road surface, a water collection well is arranged on the riverbank of the fishery breeding river, and the bottom of the water collection well extends to the roadbed layer of the road surface; transverse drainage pipes and longitudinal drainage pipes are respectively buried in the roadbed layer, a junction well is arranged at the intersection of the longitudinal drainage pipe and the transverse drainage pipe, the transverse drainage pipe and the longitudinal drainage pipe respectively pass through the junction well, the residential area drainage ditch is connected to the water collection well through the transverse drainage pipe, and a grille curbstone connected to the water collection well is arranged near the water collection well on the road surface.

[0006] Furthermore, longitudinal isolation strips are respectively arranged on both sides of the road surface, a rapid flow groove is arranged on the roadbed layer at a position corresponding to the longitudinal isolation strip, and second grid curbstones connected to the rapid flow groove are respectively arranged on both sides of the longitudinal isolation strip, wherein:

[0007] The rapids trough of the longitudinal isolation zone close to one side of the water collection well is connected to the water collection well through a second transverse drainage pipe;

[0008] The rapids trough of the longitudinal isolation zone close to one side of the residential drainage ditch is connected to the residential drainage ditch through a third transverse drainage pipe.

[0009] Furthermore, the side of the road surface close to the residential drainage ditch is connected to the residential drainage ditch through a drainage trough.

[0010] Furthermore, the grille curb is connected to the upper part of the water collection well.

[0011] Furthermore, the second transverse drain pipe and the third transverse drain pipe are both arranged above the transverse drain pipe.

[0012] Furthermore, the road surface is high in the middle and low on both sides.

[0013] Furthermore, the transverse drainage pipe is a HDPE corrugated pipe.

[0014] Furthermore, the second transverse drainage pipe and the third transverse drainage pipe are made of HDPE corrugated pipe.

[0015] Furthermore, the intersection well includes an intersection well bottom plate and an intersection well wall body arranged on the intersection well bottom plate, and the intersection well wall body is provided with transverse through holes and longitudinal through holes in sequence, the transverse through holes are used for the transverse drainage pipe to pass through, and the longitudinal through holes are used for the longitudinal drainage pipe to pass through.

[0016] Furthermore, the water collection well includes a water collection well bottom plate and a water collection well wall body arranged on the water collection well bottom plate, and the water collection well wall body is provided with an interface connected to the horizontal drainage pipe.

[0017] By adopting the above technical solution, the present invention has the following beneficial effects:

[0018] A water collection well is set on the riverbank of the fishery breeding river, and the bottom of the water collection well extends to the roadbed of the road surface; horizontal drainage pipes and longitudinal drainage pipes are buried in the roadbed respectively, and a junction well is set at the intersection of the longitudinal drainage pipe and the horizontal drainage pipe. The horizontal drainage pipe and the longitudinal drainage pipe pass through the junction well respectively. The junction well ensures that the horizontal drainage pipe and the longitudinal drainage pipe will not interfere with each other and drain water independently. The residential drainage ditch is connected to the water collection well through the horizontal drainage pipe, and a grille curb connected to the water collection well is set near the water collection well on the road surface. When it rains, rainwater polluted by vehicles passing by enters the water collection well through the grille curb and flows into the residential drainage ditch through the horizontal drainage pipe, avoiding the polluted rainwater from being directly discharged into the river and causing economic losses to local fishermen. The sewage discharged into the residential drainage ditch is purified by the sewage treatment plant and then discharged into the river through the road culvert. At the same time, the long-term scouring of the embankment along the river side by rainwater is avoided, thereby ensuring the quality of roadbed construction. BRIEF DESCRIPTION OF THE DRAWINGS
