Abstract
Description
Technical Field
[0001] This application relates to the field of urban drainage system technology, and in particular to a dredging-capable slotted linear drainage ditch. Background Technology
[0002] The importance of drainage systems in urban infrastructure construction is self-evident, giving rise to new-generation urban stormwater management concepts such as "sponge cities." Slotted linear drainage ditches, a common drainage facility in sponge cities, are designed to collect rainwater runoff from sidewalks and non-motorized vehicle lanes, discharging it into the municipal sewer network to prevent surface flooding and ensure road safety. Their straight design also facilitates smooth water flow and improves drainage efficiency. However, slotted linear drainage ditches are installed on non-motorized vehicle lanes, which are located between municipal road green belts and sidewalks. These lanes are prone to clogging by garbage, leaves, sand, and other debris. Currently, prefabricated slotted linear drainage ditches cannot be manually maintained or cleaned after construction, and clogging can even lead to blackening and foul odors, polluting the road and severely impacting drainage effectiveness. Utility Model Content
[0003] To address the aforementioned issues, this technical solution provides a dredging-capable slotted linear drainage ditch.
[0004] To achieve the above objectives, the technical solution is as follows:
[0005] A dredging-capable slotted linear drainage ditch, including
[0006] A water tank component has a U-shaped inner cavity that extends through the front and rear end faces and the top surface of the water tank component; multiple water tank components are connected front to back to form a drainage channel;
[0007] A support member is detachably connected to the water tank component; two support members are respectively installed on the left and right sides of the top surface of the water tank component, and the two support members are spaced apart to form a cleaning channel that connects to the drainage channel;
[0008] A cover, which is detachably connected to the support and is used to cover between the two supports to fill the cleaning channel.
[0009] The dredging-capacitated slotted linear drainage ditch described above also includes a detection well for connecting multiple of the drainage channels.
[0010] As described above, a dredging-capacity slotted linear drainage ditch includes a support member comprising a transverse portion on one side that abuts against the top surface of the water trough and a vertical portion connected to the other side of the transverse portion. When the water trough and the support member are embedded underground as a whole, the transverse portion restricts the support member from being pulled out of the ground in the vertical direction.
[0011] As described above, a slit-type linear drainage ditch capable of dredging has a T-shaped cover that includes a filling portion for filling the dredging channel and a support portion disposed on the top surface of the filling portion and extending to both sides, the top surface of the support portion abutting against the support portion.
[0012] As described above, in a dredging-capable slotted linear drainage ditch, a limiting mechanism is provided between the water tank and the support member to restrict their relative movement.
[0013] As described above, in a dredging-capable slotted linear drainage ditch, the limiting mechanism includes longitudinal limiting plates respectively disposed on the front and rear ends of the support member. When the support member is connected to the water tank member, the two longitudinal limiting plates respectively abut against the front and rear end faces of the water tank member.
[0014] As described above, a dredging-capacity slotted linear drainage ditch has a slot on the water tank component, and the limiting mechanism includes a insert on the support component. When the support component is inserted into the water tank component, the insert is inserted into the slot to restrict the movement of the support component relative to the water tank component.
[0015] As described above, in a dredging-capacity slotted linear drainage ditch, the support member is made of metal, and the limiting mechanism is integrally connected to the support member.
[0016] As described above, a dredging-capacitated slotted linear drainage ditch has a positioning groove on the front and / or rear of the water tank component, the positioning groove being for another water tank component to be inserted into, so that the two inner cavities are connected to form the drainage channel.
[0017] The beneficial effects of this application are:
[0018] This utility model provides a dredging-capacity slotted linear drainage ditch. During installation, a trench is first dug in the ground, then the water trough component is placed inside, followed by the installation of two support components with the water trough component. Finally, the cover is inserted between the two support components, and the water trough component and support components are buried underground for rigid fixation. After construction, surface runoff from sidewalks and non-motorized vehicle lanes flows through the cover into the cleaning channel, and rainwater is collected and discharged through the drainage channel. If debris such as leaves, garbage, and sand accumulates during use, it may clog the drainage channel. By disassembling the cover, appropriate cleaning tools can be used to clean the drainage channel or cleaning channel up to the sedimentation well. Removing all debris from the sedimentation well ensures that the slotted linear drainage ditch is free from clogging and guarantees smooth drainage. Attached Figure Description

[0029] A cover 3, detachably connected to the support 2, is used to cover the space between the two support 2 to fill the cleaning channel 21. The surface of the cover 3 has openings to isolate larger debris such as leaves and garbage, and to allow rainwater to enter the drainage channel.
[0030] This utility model provides a dredging-capacity slotted linear drainage ditch. During installation, a trench is first dug in the ground, then the water trough component is placed inside, followed by the installation of two support components with the water trough component. Finally, the cover is inserted between the two support components, and the water trough component and support components are buried underground for rigid fixation. After construction, surface runoff from sidewalks and non-motorized vehicle lanes flows through the cover into the cleaning channel, and rainwater is collected and discharged through the drainage channel. If debris such as leaves, garbage, and sand accumulates and clogs the drainage channel, the cover can be removed, and a cleaning tool of appropriate size can be used to clean the drainage channel or cleaning channel up to the sedimentation well. Removing all debris from the sedimentation well ensures that the slotted linear drainage ditch is free from clogging and guarantees smooth drainage. Because it can remove clogging, ensuring continuous drainage, its drainage capacity is superior to ordinary point drainage systems and existing slotted linear drainage ditches.
[0031] Furthermore, as a preferred embodiment of this solution, and not a limitation thereof, it also includes inspection wells 4 for connecting multiple drainage channels 12. This facilitates the collection of debris cleared from the drainage channels. In this embodiment, a single drainage channel is 1 meter long, and an inspection well (i.e., a sedimentation well) is installed every 30 meters. The bottom of the inspection well is connected to the municipal pipe network.
[0032] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the support member 2 includes a horizontal portion 22 that abuts against the top surface of the water tank member 1 on one side, and a vertical portion 23 that connects to the other side of the horizontal portion 22. When the water tank member 1 and the support member 2 are embedded underground as a whole, the horizontal portion 22 restricts the support member 2 from being pulled out of the ground in the vertical direction.
[0033] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the cover 3 is T-shaped and includes a filling portion 31 for filling the cleaning channel 21, and a support portion 32 provided on the top surface of the filling portion 31 and extending to both sides, wherein the top surface of the support 2 abuts against the support portion 32.
[0034] Furthermore, as a preferred embodiment of this solution and not a limitation, a limiting mechanism 5 is provided between the water tank component 1 and the support component 2 to restrict their relative movement, thus preventing displacement during installation.
[0035] Furthermore, as a preferred embodiment of this solution and not a limitation, the limiting mechanism 5 includes longitudinal limiting pieces 51 respectively disposed on the front and rear ends of the support member 2. When the support member 2 is connected to the water tank member 1, the two longitudinal limiting pieces 51 respectively abut against the front and rear end faces of the water tank member 1.
[0036] Furthermore, as a preferred embodiment of this solution and not a limitation, the sink component 1 is provided with a slot 13, and the limiting mechanism 5 includes an insert 52 provided on the support component 2. When the support component 2 is inserted into the sink component 1, the insert 52 is inserted into the slot 13 to restrict the movement of the support component 2 relative to the sink component 1.
[0037] Furthermore, as a preferred embodiment of this solution and not a limitation, the support member 2 is made of metal, and the limiting mechanism 5 is integrally connected to the support member 2. The metal is generally stainless steel, but galvanized iron sheets or other materials can also be used. The use of stainless steel metal structures offers several advantages: 1. Due to the thin material dimensions and light weight, construction is convenient; 2. The material has high strength, and concrete construction after installation will not damage the material or easily cause cracking or deformation, ensuring construction quality and efficient drainage; 3. Overall durability is good, with a longer service life than other materials; 4. The slotted linear drainage ditch has beautiful lines, blending seamlessly with the environment, representing an upgrade and improvement over traditional linear drainage ditches.
[0038] Furthermore, as a preferred embodiment of this solution and not a limitation, the water tank component 1 is provided with a positioning groove 14 on the front and / or rear, the positioning groove 14 for another water tank component 1 to be inserted, so that the two inner cavities 11 are connected to form the drainage channel 12.
