Description

Technical Field

[0001] The utility model belongs to the technical field of municipal environmental engineering, and particularly relates to a waterlogging drainage facility suitable for municipal roads in plain river network areas. Background Art

[0002] The rainwater inlet is the entrance for surface runoff rainwater to enter the municipal rainwater pipe network. It consists of a water inlet grate, a well body and a connecting pipe. Surface runoff rainwater is collected through the rainwater inlet and enters the municipal rainwater pipe network. It is then transferred to the river through the rainwater pipe network to reduce the impact of rainwater on municipal roads.

[0003] According to the "Outdoor Drainage Design Standard" (GB50014-2021), for rainfall below the municipal stormwater canal design standard (2 to 10 years), the road surface is allowed to have no more than 15 cm of water accumulation, and the allowable water withdrawal time is 0.5 to 4 hours; for rainfall exceeding the municipal stormwater canal design standard, the road surface is allowed to have more than 15 cm of water accumulation, and the water withdrawal time is long, and the road surface waterlogging poses a threat to the safety of pedestrians and passing vehicles. The rainy season is concentrated in plain river network areas, and rainfall that exceeds the municipal stormwater canal design standard occurs frequently, posing a threat to the safety of municipal roads. In order to avoid rivers, municipal roads in plain river network areas have many undulating sections. When the rainfall intensity exceeds the municipal stormwater canal design standard, water accumulates on the municipal road surface, which is particularly serious at the lowest vertical point of the municipal road.

[0004] At present, a Chinese utility model with the publication number of CN211285918U discloses a municipal road drainage device, which relates to a municipal road drainage device. It is composed of a manhole cover, a movable frame, a support rod, a left end rotating shaft, a lever, a hinge seat, a right end rotating shaft, an electric telescopic rod and a raindrop sensor. A movable frame is installed under the manhole cover, a raindrop sensor is installed on the movable frame, a support rod is installed under the movable frame, the support rod is connected to the left end rotating shaft, the left end rotating shaft is connected to the lever, the fulcrum of the lever is the hinge seat, the other side of the lever is connected to the right end rotating shaft, and the right end rotating shaft is connected to the electric telescopic rod. The movable frame of the utility model can be raised when it rains, which can prevent garbage from blocking the drainage outlet, so that drainage can proceed smoothly, and can be automatically retracted after the rain ends.

[0005] At present, when the rainfall intensity exceeds the design standard of the municipal stormwater pipes, the municipal road stormwater inlets on the market cannot quickly discharge the rainwater that exceeds the design standard, and due to restrictions such as the development of surrounding plots, some municipal roads cannot be set up at low points for drainage. The road surface water is blocked by side strips or crosswalks, and the accumulated water cannot be discharged to drainage ditches, parks, green spaces or natural water bodies other than the road red line; and when the water level of the inner river downstream of the municipal road stormwater pipe rises, it will support the water level of the municipal road stormwater pipe and extend the water withdrawal time. Utility Model Content

[0006] The utility model aims to provide a waterlogging drainage facility suitable for municipal roads in plain river network areas, which has the advantages of accelerating the discharge of water from municipal roads, shortening the water withdrawal time, and reducing the impact of road surface water on municipal roads.

[0007] The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: a water drainage facility suitable for municipal roads in plain river network areas, including a rainwater well, an overflow well and a gate valve well, the rainwater well is buried at the bottom of one side of the road and is 30 mm lower than the road surface, the overflow well and the gate valve well are respectively buried in sequence on the other side of the rainwater well away from the bottom of the road, a water inlet grate is installed on the top of the rainwater well, the top between the rainwater well and the overflow well is fixedly connected with an overflow pipe, the bottom of the rainwater well away from one end of the overflow well is fixedly connected with a rainwater pipe, and the inside of the gate valve well is penetrated and fixedly connected with a water outlet pipe connected to the overflow well.

[0008] By adopting the above technical scheme, when the flood discharge capacity of the rainwater pipe cannot meet the requirements, the rainwater level rises and flows into the overflow well through the overflow pipe, and then the rainwater in the overflow well is transmitted to the drainage ditch, park green space or natural water body outside the road through the outlet pipe for discharge, thereby effectively accelerating the discharge of water from municipal roads and shortening the water withdrawal time; reducing the impact of road surface water on municipal roads; when the rainwater passes through the overflow well, sand and gravel are deposited, and after the drainage of the accumulated water is completed, the motor is turned on to drive the auger to rotate to bring out the sand and gravel accumulated in the sand settling tank and discharge it from the opening of the cover, thereby facilitating the dredging of internal waterlogging drainage facilities and improving the dredging efficiency.

[0009] The utility model is further configured as follows: a sand settling trough is provided at the bottom of the inner cavity of the overflow well, a sand discharge pipe is fixedly connected to one side of the bottom of the overflow well, a motor is installed at the end of the sand discharge pipe away from the overflow well, an auger is fixedly connected to the output end of the motor and is rotatably connected to the sand settling trough and the sand discharge pipe, and a cover is bolted to the bottom of the end of the sand discharge pipe away from the overflow well.

[0010] The above technical solution is adopted to facilitate the dredging of the waterlogging drainage facilities. At the same time, water can be manually flushed into the waterlogging drainage facilities, so that the silt inside the pipe is brought into the sand settling tank and then brought out through the auger, thereby improving the dredging efficiency.

[0011] The utility model is further configured as follows: a concrete cushion layer is poured at the bottom of the rainwater well and the overflow well.

[0012] By adopting the above technical solution, the bottom of the rainwater well and the overflow well are supported to avoid sinking.

[0013] The utility model is further configured as follows: a gate valve is installed at one end of the water outlet pipe close to the inside of the gate valve well, and a gate valve well cover used in conjunction with the gate valve is installed on the top of the gate valve well.

[0014] By adopting the above technical solution, whether the waterlogging drainage facilities are in operation can be controlled by opening or closing the gate valve.

[0015] The utility model is further configured as follows: an overflow well cover is installed on the top of the overflow well, and the tops of the inner cavities of the rainwater well, the overflow well and the gate valve well are fixedly connected with support beams respectively used in conjunction with the water inlet grate, the overflow well cover and the gate valve well cover.

[0016] The above technical solution is adopted to support and reinforce the bottom to improve stability.

[0017] The utility model is further configured as follows: a road curbstone fixedly connected to the side of the road is arranged on one side of the top of the rainwater well.

[0018] The above technical solution is adopted to prevent the accumulated water from flowing out to the side of the road surface, thereby improving the drainage effect of the accumulated water.

[0019] The utility model is further configured as follows: one end of the rainwater pipe away from the rainwater well is fixedly connected to the municipal drainage system, and one end of the outlet pipe away from the overflow well is fixedly connected to a drainage ditch, a park green space or a natural water body.

[0020] The adoption of the technical solution makes it easy to drain the accumulated water in time and improve the utilization rate of the accumulated water.

[0021] The utility model is further configured as follows: one end of the overflow pipe close to the overflow well and one end of the outlet pipe close to the gate valve well are inclined downward, and the inclination gradient of the overflow pipe and the outlet pipe is 1%.

[0022] By adopting the above technical solution, the accumulated water can fall naturally by gravity, thereby improving the fluidity of the accumulated water.

[0023] In summary, the utility model has the following beneficial effects:

[0024] 1. When the flood discharge capacity of the rainwater pipe cannot meet the requirements, the rainwater level rises and flows into the overflow well through the overflow pipe, and then the rainwater in the overflow well is transmitted to the drainage ditch, park green space or natural water body outside the road through the outlet pipe for discharge, thereby effectively accelerating the discharge of water on municipal roads and shortening the water withdrawal time; reducing the impact of road surface water on municipal roads;

[0025] 2. When rainwater passes through the overflow well, sand and gravel are deposited. After the accumulated water is drained, the motor is turned on to drive the auger to rotate and the sand and gravel accumulated in the sand settling tank are brought out from the opening of the cover to be discharged, thereby facilitating the dredging of the internal waterlogging drainage facilities and improving the efficiency of dredging.
