Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a rainwater well structure with dual interception and rapid drainage. Background Technology

[0002] With the continuous improvement of urban drainage systems, rainwater wells are widely used in roads, squares, and residential areas to collect and discharge rainwater. To prevent solid debris such as leaves, plastic bags, and gravel from entering the municipal drainage network, existing rainwater wells are usually equipped with intercepting structures such as intercepting baskets, filter plates, or filter screens to intercept solid debris in rainwater.

[0003] However, existing rainwater wells have at least the following shortcomings: Existing interception structures are usually set up on the main flow path of rainwater. Rainwater must pass through the interception structure before entering the drainage pipe. When solid debris accumulates, it can easily cause blockage of the interception structure, resulting in a decrease in rainwater discharge capacity and water accumulation during heavy rainfall.

[0004] Existing sewage interception structures typically only have a single-stage sewage interception function. After long-term accumulation, solid debris can easily enter the drainage pipes with the water flow, causing blockages and affecting the normal operation of the drainage system.

[0005] Most of the existing intercepting components in rainwater wells are fixedly installed, requiring workers to enter the wells for cleaning, resulting in low maintenance efficiency, high labor intensity, and certain safety hazards.

[0006] Therefore, it is necessary to provide a rainwater well structure with dual interception and rapid drainage to solve the problems of low drainage efficiency, poor interception effect and inconvenient maintenance of existing rainwater wells. Summary of the Invention

[0007] The purpose of this invention is to overcome the defects of the prior art and provide a rainwater well structure with dual interception and rapid drainage. The well body is divided into an interception chamber and a drainage chamber by a vertically arranged permeable isolation component, and dual interception is achieved by an inclined permeable flow guiding component. A quick-cleaning sewage collection component is installed in the interception chamber, so as to achieve the effects of high efficiency in interception, smooth drainage and convenient maintenance.

[0008] To achieve the above objectives, the technical solution adopted by this invention is a rainwater well structure with dual interception and rapid drainage, comprising: Well body; A permeable isolation component is vertically installed in the middle of the well body to divide the well body into a sewage interception chamber and a drainage chamber. The bottom of the drainage chamber is connected to a drainage pipe. The permeable isolation component is provided with pores to allow water in the sewage interception chamber to flow into the drainage chamber and be discharged through the drainage pipe. A permeable guide component is placed at the top of the drainage well chamber and is inclined downward from one side of the drainage well chamber to the other side of the intercepting well chamber. It is used to allow rainwater to pass through and block solid debris in the rainwater, so that the solid debris slides along the permeable guide component to the intercepting well chamber. A sludge collection component is installed in the sludge interception well chamber to collect solid debris entering the chamber.

[0009] A further improvement of the rainwater well structure of the present invention with dual interception and rapid drainage is that the permeable isolation component includes: A permeable plate is vertically installed inside the well body, with the top of the permeable plate lower than the top surface of the well body, and the pores are formed on the permeable plate; Multiple pairs of U-shaped clips are spaced apart along the height of the well body. Each pair of U-shaped clips is pre-embedded on both sides of the well body with their openings facing each other to form an installation space for inserting the permeable plate.

[0010] A further improvement of the rainwater well structure of the present invention with dual interception and rapid drainage is that two rows of limiting bricks are also built at the bottom of the well body. The two rows of limiting bricks are located on both sides of the designed installation position of the permeable plate to form an insertion space for the bottom end of the permeable plate to be accommodated.

[0011] A further improvement of the rainwater well structure of the present invention with dual interception and rapid drainage is that the permeable flow guiding component includes a stainless steel baffle. One end of the stainless steel baffle is detachably connected to the drainage well chamber, and the other end is inclined downward toward the interception well chamber. Permeable holes are spaced apart on the stainless steel baffle.

[0012] A further improvement of the rainwater well structure of the present invention with dual interception and rapid drainage is that a debris-blocking net is connected to the inner wall of the drainage well. The debris-blocking net is located below the stainless steel baffle and is used to perform secondary interception of rainwater passing through the stainless steel baffle.

[0013] A further improvement of the rainwater well structure of the present invention with dual interception and rapid drainage is that the sewage collection component includes a sewage interception box, which is set at the bottom of the sewage interception well chamber for collecting solid debris in the sewage interception well chamber, and the sewage interception box is adapted to the sewage interception well chamber.

[0014] A further improvement of the rainwater well structure of the present invention with dual interception and rapid drainage is that the interception box includes a frame and a steel mesh connected to the outer periphery of the frame, the steel mesh being used to allow rainwater to pass through and block solid debris.

[0015] A further improvement of the rainwater well structure of the present invention with dual interception and rapid drainage is that a well ring is provided at the top of the well body. The well ring includes an outer frame and a reinforcing beam connected to the inner side of the outer frame. The reinforcing beam is directly opposite the permeable plate.

[0016] Compared with the prior art, the advantages of the present invention are: By installing a permeable isolation component in the middle of the well body to divide the well body into a sewage interception chamber and a drainage chamber, and installing an inclined permeable flow guide component on the top of the drainage chamber, a dual sewage interception effect is achieved: "the flow guide component initially intercepts and guides sewage, and the permeable isolation component performs secondary sewage interception and filtration." Debris in the sewage interception chamber is effectively intercepted, and no debris enters the drainage chamber, ensuring the long-term smooth flow of the drainage pipe and avoiding road water accumulation caused by debris blockage.

[0025] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0026] The structure of the rainwater well with dual interception and rapid drainage of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Please see Figures 1-6 As shown, the structure of the dual-interception and rapid drainage rainwater well includes: Well body 4; A permeable isolation component is vertically installed in the middle of the well body 4 to divide the well body 4 into a sewage interception chamber 2 and a drainage chamber 3. The bottom of the drainage chamber 3 is connected to a drainage pipe 13. The permeable isolation component is provided with pores to allow water in the sewage interception chamber 2 to flow into the drainage chamber 3 and be discharged through the drainage pipe 13. A permeable guide component is placed at the top of the drainage well chamber 3 and is inclined downward from one side of the drainage well chamber 3 to the side of the intercepting well chamber 2. It is used to allow rainwater to pass through and block solid debris in the rainwater, so that the solid debris slides along the permeable guide component to the intercepting well chamber 2. A sludge collection component is installed inside the sludge interception chamber 2 to collect solid debris that enters the sludge interception chamber 2.

[0028] The well body is divided into a sewage interception chamber 2 and a drainage chamber 3 by a vertically arranged permeable isolation component. The inclined permeable diversion component achieves dual sewage interception. A sewage collection component that can be cleaned quickly is installed in the sewage interception chamber 2, so as to achieve the effects of efficient sewage interception, smooth drainage and convenient maintenance.

[0029] Specifically, the top of the intercepting well chamber 2 is also connected to a permeable pipe 12, which is used to collect the accumulated water in the surrounding soil and guide it to the intercepting well chamber 2.

[0030] Water collected from the surrounding soil through the permeable pipe 12 is discharged into the intercepting well chamber 2, reducing the leakage pressure and settlement risk of the well body 4 caused by the rise in groundwater level; at the same time, the introduction of clean water can promote the flow of water in the intercepting well chamber 2, avoid long-term stagnant water accumulation leading to odor, and improve the environment inside the well.

[0031] Preferably, the permeable barrier component includes: A permeable plate 5 is vertically installed inside the well body 4, and the top of the permeable plate 5 is lower than the top surface of the well body 4. The pores are formed on the permeable plate 5. Multiple pairs of U-shaped clips 6 are spaced apart along the height of the well body 4. Each pair of U-shaped clips 6 is pre-embedded on both sides of the well body 4 with their openings facing each other, so as to form an installation space for inserting the permeable plate 5.

[0032] By using U-shaped blocks 6 that are consistent with the masonry module of the well body 4 and pre-embedded in the well wall, during installation, it is only necessary to insert the permeable plate 5 from top to bottom into the installation space formed by the blocks. The construction is simple and does not change the masonry habits.

[0033] Specifically, the spacing between the two flanges of each U-shaped block 6 is adapted to the thickness of the permeable plate 5.

[0034] Preferably, the bottom of the well body 4 is also constructed with two rows of limiting bricks 15, which are located on both sides of the designed installation position of the permeable plate 5 to form an insertion space for the bottom end of the permeable plate 5.

[0035] The insertion space is formed by two rows of limiting bricks 15 at the bottom of the well. After the bottom end of the permeable plate 5 is inserted, the bottom positioning and limiting can be achieved. It works with the U-shaped locking blocks 6 on both sides to form multi-point restraint, preventing the permeable plate 5 from shifting and overturning under the impact of water flow or ground vibration. At the same time, the limiting bricks 15 are completed simultaneously with the well body 4, without the need for additional pre-embedding process, and the operation is simple.

[0036] Preferably, the permeable flow guiding component includes a stainless steel baffle 8, one end of which is detachably connected to the drainage well chamber 3, and the other end is inclined downward toward the intercepting well chamber 2. The stainless steel baffle 8 is provided with permeable holes spaced apart.

[0037] like Figure 4 As shown: Through the inclined stainless steel baffle 8, rainwater flows directly down to the drainage well chamber 3 through the water permeable holes, while solid debris is intercepted by the baffle and slides down the inclined surface into the intercepting well chamber 2, thus achieving solid-liquid separation.

[0038] Specifically, the lower end of the stainless steel baffle 8 rests on top of the permeable plate 5.

[0039] By placing the lower end of the stainless steel baffle 8 on top of the permeable plate 5, the support stability of the stainless steel baffle 8 is improved.

[0040] Specifically, two connecting rods 9 are spaced apart in the drainage well chamber 3 along the line connecting the drainage well chamber 3 and the intercepting well chamber 2. The installation height of the connecting rod 9 that is closer to the intercepting well chamber 2 is lower than the installation height of the other connecting rod 9. The bottom of the stainless steel baffle 8 has two slots for engaging with the two connecting rods 9 respectively, so that the stainless steel baffle 8 is tilted.

[0041] Two connecting rods 9 at different installation heights are engaged with the bottom slots of the baffle to naturally form an inclination angle. No additional support is required, making installation quick and easy. The height difference precisely controls the inclination angle, ensuring that solid debris slides smoothly down the baffle surface into the intercepting well chamber 2.

[0042] Specifically, the top of the stainless steel baffle 8 is connected to a handle 10.

[0043] By installing a handle 10 on the top of the stainless steel baffle 8, construction workers can remove the baffle by simply pulling the handle 10 without having to enter the well during cleaning and maintenance. This makes the operation convenient and labor-saving, and improves the safety and efficiency of the cleaning operation.

[0044] Preferably, the inner wall of the drainage well chamber 3 is connected to a debris barrier 14, which is located below the stainless steel baffle 8 and is used to perform secondary debris barrier on rainwater passing through the stainless steel baffle 8.

[0045] By adding a debris-blocking net 14 below the stainless steel baffle 8, rainwater passing through the permeable holes of the baffle is intercepted a second time, effectively trapping fine suspended matter and debris that cannot be blocked by the permeable holes, further ensuring the cleanliness of the water in the drainage well chamber 3, and reducing solid pollutants entering the drainage pipe 13 and municipal pipe network.

[0046] Specifically, the inner wall of the drainage well chamber 3 is connected with multiple hooks at intervals, and the debris net 14 is hung on multiple of these hooks.

[0047] By setting up this hook to connect with the debris barrier 14, the debris barrier 14 can be quickly installed and removed, improving construction efficiency.

[0048] Preferably, the waste collection assembly includes a waste collection box 11, which is disposed at the bottom of the waste collection chamber 2 for collecting solid debris in the waste collection chamber 2, and the waste collection box 11 is adapted to the waste collection chamber 2.

[0049] Specifically, the planar dimensions of the intercepting bin 11 match the internal planar dimensions of the intercepting well chamber 2.

[0050] By setting the planar dimensions of the intercepting box 11 to match the internal planar dimensions of the intercepting well chamber 2, it is ensured that all solid debris sliding down from the permeable diversion component and intercepted by the permeable isolation component falls into the intercepting box 11, preventing debris from scattering into the gap between the intercepting box 11 and the well wall, and preventing debris from accumulating and rotting at the bottom of the well or blocking the drainage channel; at the same time, after the intercepting box 11 is placed, there is no wobbling gap between it and the well wall, and the positioning is stable, preventing displacement due to water flow impact.

[0051] Specifically, the intercepting box 11 is connected to a pull rope that extends upward out of the well body 4, allowing construction personnel to lift and remove the intercepting box 11.

[0052] By setting up a pull rope extending from the well body 4, construction personnel do not need to go down into the well or probe into it during cleaning and maintenance. They can simply stand on the road and pull the rope to remove the intercepting box 11. This operation is convenient and labor-saving, avoiding the safety risks caused by oxygen deficiency or the accumulation of harmful gases in the well. At the same time, it greatly shortens the time for a single cleaning operation and improves maintenance efficiency.

[0053] Specifically, the intercepting tank 11 is connected to a plurality of rollers at intervals around its perimeter. When the intercepting tank 11 is located inside the intercepting well chamber 2, the plurality of rollers abut against the inner wall of the intercepting well chamber 2.

[0054] The rollers around the intercepting box 11 press against the inner wall of the intercepting well chamber 2. When it is lifted, the rollers roll along the well wall, which transforms sliding friction into rolling friction, greatly reducing the lifting resistance and making it easier and less strenuous to remove the intercepting box 11. At the same time, the rollers limit the intercepting box 11 on all four sides, preventing the box from shaking or shifting inside the well and ensuring that it is always placed in the center and accurately positioned.

[0055] Specifically, another installation example of the intercepting box 11 is provided: the intercepting box 11 is connected to the wellhead of the intercepting chamber 2, and the top surface of the intercepting box 11 is flush with the top surface of the permeable plate 5. The inner wall of the intercepting chamber is provided with support protrusions for the intercepting box 11 to rest on.

[0056] By connecting the intercepting box 11 to the wellhead of the intercepting well chamber and making its top surface flush with the top surface of the permeable plate 5, solid debris sliding down from the stainless steel baffle 8 can fall directly into the intercepting box 11 without having to pull it up from the bottom of the well with a rope. Maintenance personnel can directly remove and place the intercepting box 11 after opening the rainwater grate 7, making the cleaning operation more convenient, labor-saving and safe.

[0057] Preferably, the intercepting bin 11 includes a frame and a steel mesh connected to the periphery of the frame, the steel mesh being used to allow rainwater to pass through and block solid debris.

[0058] The intercepting box 11 is constructed by a frame and a steel mesh. The frame provides overall structural strength, while the steel mesh enables solid-liquid separation by allowing rainwater to pass through and intercepting solid debris. This ensures smooth water flow within the intercepting chamber 2 and allows for the centralized collection of debris, facilitating regular removal and cleaning.

[0059] Preferably, a well ring 1 is provided on the top of the well body 4. The well ring 1 includes an outer frame and a reinforcing beam connected to the inner side of the outer frame. The reinforcing beam is directly opposite the permeable plate 5.

[0060] The precast well ring, consisting of an outer frame and reinforcing beams, replaces the traditional brick well ring, resulting in high structural strength. It effectively transfers vehicle loads to the surrounding area of ​​the well body 4, preventing the well ring 1 from cracking and uneven settlement. The reinforcing beams divide the well ring 1 into two water inlet areas corresponding to the sewage interception chamber 2 and the drainage chamber 3, respectively. The drainage flow area is large, ensuring water inlet capacity during heavy rain. The precast well ring is installed with grout, which is quick to construct, has high installation accuracy, and is convenient for later maintenance and replacement.

[0061] Specifically, a lifting ring is connected to the top of the well ring 1.

[0062] By installing the lifting ring on the top of the well ring 1, the installation is facilitated and the construction efficiency is improved.

[0063] Specifically, each of the water inlet areas of the well ring 1 is covered with a rain grate 7, and the pull rope is connected to the corresponding rain grate 7.

[0064] By connecting the pull rope to the rainwater grate 7 of the corresponding intercepting well chamber 2, the intercepting box 11 can be pulled to the well opening when the rainwater grate 7 is opened during cleaning. There is no need to reach into the well to find the pull rope. The operation is smooth and labor-saving, which greatly shortens the cleaning time of a single operation. In addition, the pull rope does not occupy the space outside the well, avoiding the risk of pedestrians tripping.

[0065] Specifically, after the construction of the rainwater well structure is completed, the municipal roads around it are constructed to slope the municipal roads towards the well body.

[0066] By sloping the municipal road towards the manhole 4, rainwater on the road surface will naturally converge towards the rainwater well under the action of gravity, which effectively improves the rainwater collection efficiency and avoids local water accumulation on the road surface. At the same time, the sloping road surface and the manhole opening form a natural connection, ensuring the smoothness of vehicle driving, reducing the bumps or damage caused by the height difference at the edge of the rainwater grate 7, and extending the service life of the facility.

[0067] The construction process of the rainwater well structure is as follows: Figure 6 As shown: First, prefabricate the permeable slab 5, U-shaped clamps 6, and well ring 1 respectively. Then, excavate the well body 4 and pour a concrete base slab. Next, construct the well body 4. During the construction process, simultaneously install the U-shaped clamps 6 into both sides of the well wall according to the design position and connect the drainage pipe 13 to the well body 4. After the construction is completed, insert the permeable slab 5 into the installation space of the U-shaped clamps 6 and fix it, so that the well body 4 is divided into a sewage interception chamber 2 and a drainage chamber 3. Then, backfill and compact the soil around the well in layers, and install the prefabricated well ring 1 and rainwater grate 7 on the top of the well body 4. Then, make a stainless steel baffle 8 and a sewage interception box 11. Place the sewage interception box 11 at the bottom of the sewage interception chamber 2, and install the stainless steel baffle 8 in the drainage chamber 3 and tilt it towards the sewage interception chamber 2. Finally, carry out municipal road construction. During operation, the sewage interception box 11 and stainless steel baffle 8 can be removed and cleaned periodically.
