Roads and drainage ditches are usually installed according to the terrain. However, at concave points on the road's longitudinal slope and at intersections, rainwater from the drainage ditch has no outlet. How to effectively connect it with the road's stormwater drainage system to solve the problem of rainwater outlet at these concave points is a problem with existing technology. Summary of the Invention

[0006] Furthermore, a cushion layer is added below the bottom plate of the intercepting well, and the cross-sectional dimension of the cushion layer is larger than that of the bottom plate.

[0007] Furthermore, the net height H of the well wall is the same as the inner bottom of the drainage pipe, which is determined by the soil cover depth of the drainage pipe, and a sedimentation trough is set below the inner bottom of the pipe.

[0008] Furthermore, the drainage pipe is installed at the vertical center of the intercepting well and discharges into the road stormwater pipe system.

[0009] Furthermore, two rubber sealing rings are installed where the drainage pipe penetrates the well wall to enhance waterproofing.

[0010] Furthermore, a rain grate is installed on the top surface of the intercepting well, consisting of a rain grate support and a rain grate cover, with the rain grate support pre-embedded in the well wall.

[0011] Furthermore, a long pin is installed at one end of the rain grate along its length, with both ends fixed inside the well wall.

[0015] This utility model provides a road drainage ditch intercepting well, which can realize the functions of rainwater collection, convergence and sedimentation at the concave point of the road drainage ditch, and effectively connect with the road rainwater pipeline system to solve the drainage outlet problem; a sedimentation trough is set at the bottom to prevent silt from clogging the pipe; a rain grate is set on the top to effectively prevent debris from entering the municipal rainwater pipe; the rain grate is equipped with a long pin shaft, which can be flipped over during maintenance for easy cleaning.

[0016] like Figure 1 , 2 As shown in Figure 3, this utility model is installed at the concave point of the road drainage ditch. The top surface of the intercepting ditch 1 is flush with the bottom of the drainage ditch. The intercepting ditch 1 is installed at the bottom of the drainage ditch and is cast integrally with the drainage ditch. The concrete strength grade is not lower than C25. The net width B and net length L are determined comprehensively based on factors such as the flow rate and size of the drainage ditch and maintenance requirements. The net width B is not less than the net width of the drainage ditch, generally ≥600mm, and it is not recommended to exceed 1000mm. The net length L is ≥800mm, and it is not recommended to exceed 1200mm. The thickness C of the surrounding manhole walls 2 is generally ≥300mm, and the thickness D of the base plate 3 is generally ≥300mm. A concrete pad 4 is added at the bottom, with a concrete strength grade not lower than C20 and a thickness E generally 100mm, extending 100mm beyond the outer edge of the manhole walls 2 on each side. The clear height H of the well wall 2 is the same as the clear height of the inner bottom of the drainage pipe 5, determined by the soil cover depth of the drainage pipe 7, generally ≥1000mm, and not recommended to exceed 1500mm. A sedimentation trough with a depth F of 300~500mm is installed below the inner bottom of the pipe. The drainage pipe 5 is installed at the vertical middle position of the intercepting well 1 and flows into the road stormwater pipe system with a slope of 0.3%~1%.
