Description
Technical Field
[0001] The utility model relates to the technical field of overflow wells, in particular to an assembled overflow well. Background Art
[0002] The overflow well is a type of drainage inspection well, which is generally found in intercepting combined sewer systems and urban drainage engineering pump station systems, and has the function of controlling water flow.
[0003] The overflow well for diverting rainwater, also known as the rainwater infiltration well, is part of the construction of sponge cities. It can quickly, conveniently and safely infiltrate rainwater into the ground, fully replenish groundwater, and effectively avoid ground water accumulation and urban waterlogging. It can also be used as a drainage inspection well, overflow well, etc.
[0004] Nowadays, rainwater overflow wells are generally buried underground in urban greening and park green spaces. When rainwater falls on urban green spaces, it will enter the sunken green spaces. If the rainfall is too heavy, water will accumulate in the green spaces. If it is not drained out in time, the accumulated water will soak the roots and rhizomes of the green spaces and continue to accumulate, making it impossible to use the green spaces normally. Of course, during the regular watering of green spaces, more water will accumulate. Excess water needs to be drained out of the green spaces to avoid continuous waterlogging of the green spaces. This can also keep the surface of the green spaces stable and dry, and prevent them from becoming muddy and dirty.
[0005] Generally, green space drainage needs to go through an overflow well. The overflow pipe is set above the root system of the green space. Water that exceeds the root system's demand will be drained and collected through the overflow pipe. The overflow pipe will drain the collected accumulated water into the overflow well and then discharge it. Part of it will be collected into the perforated blind pipe through infiltration, and then discharged into the overflow well, and then discharged to the downstream rainwater well through the overflow pipe.
[0006] The existing overflow wells are pre-built with bricks and stones, and there are three disadvantages in building overflow wells. First, the seepage pipe for draining the accumulated water in the overflow well must be at least level with the overflow drainage pipe to ensure smooth drainage of the blind pipe. In reality, the relative elevation of the seepage pipe and the overflow drainage pipe is often ignored during construction, resulting in construction errors and poor drainage of the brick-built overflow well. As a result, the drainage function of the sunken green space is affected, and rainwater cannot be discharged along the slope, resulting in water accumulation. Second, building overflow wells requires a long construction period and more construction personnel, which is not conducive to construction. Some green spaces do not have overflow wells. With the difficulty of drainage, it is necessary to increase overflow wells or recreate more overflow wells to increase the drainage speed. This kind of brick-built overflow well is difficult to transform and difficult to carry out construction and transformation in existing green spaces. It requires on-site cement and mortar for bricklaying, and the construction and transformation method is too destructive to the green space. Third, the construction level of the overflow well is often affected by the subjective factors of the construction workers. It is difficult to measure the height of underground pipe laying. Generally, it is necessary to carry out construction on the vacant land before filling. After the overflow well is completed, filling will be carried out. However, the existing overflow well can only be constructed in advance, and the construction period is long. Once the construction is different from the actual situation and needs to be modified, it is difficult to transport a large amount of original earthwork during construction. After the overflow well is built, the earthwork is backfilled. The existing green overflow well transformation can only be carried out by excavating on the adobe and finally planting green plants. This construction method is all excavated on the land, and it is difficult to determine the elevation of the overflow well. It is easy to make mistakes, resulting in poor overflow effect. Moreover, the top area of the brick-built overflow well may be different in size and direction due to different construction workers, which makes it difficult to accurately fit the overflow well cover. The size needs to be adjusted by filling cement, resulting in the lack of beauty of the well cover, thereby affecting the landscape function of the sunken green space.
[0007] Based on this, the utility model designs an assembled overflow well to solve the above problems. Utility Model Content
[0008] The purpose of the utility model is to provide an assembled overflow well, which can collect and drain the accumulated water in the green space through the seepage pipe, so that the seepage pipe can collect and drain the water that cannot continue to seep into the soil layer through the drainage pipe, so as to avoid the accumulation of water in the green space; if there is heavy rain or rainstorm, the rainwater fails to seep in time, and the rainwater will accumulate in the sunken green space, and the accumulated water will pass through the rainwater grate and flow directly into the overflow pipe in the overflow well along the water collection bucket, and then through the drainage pipe, the accumulated water on the ground will be drained to the downstream rainwater well, so as to effectively avoid the accumulation of water on the surface and underground of the green space.

The installation is more convenient and the construction is simpler. Wherever an overflow well is needed, the surface is excavated, the pipe is buried, and then it is connected to the drainage pipe.

[0033] See also Figures 1 to 5 As shown, the utility model provides an assembled overflow well. In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings in the specification and specific implementation methods.
[0034] In a specific embodiment of the technical solution of the utility model:
[0035] It includes a water collecting bucket 1, a water seepage pipe 2, a reducing joint 3, a rainwater grate 4 and an overflow pipe 5;
[0036] The water collecting bucket 1 is a funnel-shaped structure with upper and lower openings. The top of the water collecting bucket 1 is an overflow inlet 11. The lower opening of the water collecting bucket 1 is detachably connected to an extension tube 12.
[0037] The rainwater grate 4 is a flat plate structure with mesh holes, and the rainwater grate 4 can be flipped open and embedded in the overflow inlet 11 through a hinge 41; the top of the rainwater grate 4 in the covered state is flush with the top of the overflow inlet 11, ensuring that the accumulated water on the ground can flow smoothly along the rainwater grate 4 into the overflow well without being blocked by the rainwater grate 4.
[0038] The overflow pipe 5 is a three-way adapter, with openings at the top and left and right sides of the overflow pipe 5. The top opening of the overflow pipe 5 is detachably sealed and docked with the extension pipe 12, and the water outlet of the overflow pipe 5 is sealed and docked with the drain pipe 52; a positioning platform 51 is protruding downward at the bottom of the overflow pipe 5, and the positioning platform 51 is a closed base. The positioning platform 51 is supported at the bottom of the overflow pipe 5. The positioning platform 51 is used for positioning in the ditch at the bottom of the soil layer to ensure that the overflow pipe 5 is stable after being buried and will not move;
[0039] The inner cavity of the overflow pipe 5 is a smooth three-way pipe, and the bottom of the inner cavity of the overflow pipe 5 is flat.
[0040] The reducer 3 is a closed disc-shaped structure, the outer wall of the reducer 3 is sealed and connected to the water inlet of the overflow pipe 5, and a transfer port 31 is provided inside the reducer 3, and the diameter of the transfer port 31 is smaller than the outer diameter of the reducer 3;
[0041] The seepage pipe 2 is a round pipe with a plurality of water-permeable holes 21 on the top. The seepage pipe 2 is sealed and plugged with the adapter 31. The seepage pipe 2 is commonly used in overflow wells and is also called a seepage pipe, a drainage perforated pipe or a perforated collection pipe.
[0042] The reducer seal plug 32 is a rubber seal plug. The detachable seal plug outside the reducer seal plug 32 is tightly inserted into the transfer port 31. The reducer seal plug 32 and the transfer port 31 are interference fit.
[0043] The variable diameter sealing plug 32 is a circular tubular structure, and the inner hole of the variable diameter sealing plug 32 is tightly sealed with the seepage pipe 2. The variable diameter sealing plug 32 is used when seepage pipes 2 of different diameters are required, some are 8cm diameter pipes, and some are 5cm diameter seepage pipes 2. When it is necessary to use underground soil seepage pipes 2 of different diameters, the variable diameter sealing plug 32 can be added for connection, ensuring convenient diameter change, convenient docking, convenient use, and smoother installation.
[0044] The overflow pipe 5 is a rubber disc, the reducer 3 and the water inlet of the overflow pipe 5 are interference fit, and the water outlet of the overflow pipe 5 is connected to the drain pipe 52 through a threaded seal.
[0045] Compared with the existing technology, the structure of the embodiment of the utility model has the following differences:
[0046] 1. Existing overflow wells in green areas are built by brick and stone masonry, which is cumbersome to construct and takes a long time to complete. In addition, cement solidification and maintenance are required, which makes the construction difficult. A modular structure is formed by splicing. The modular structure makes it easy to excavate and assemble the entire overflow well, and it is convenient to only dig a ditch for burying the pipe. The soil can be backfilled immediately after the device is buried. The operation is simple and the construction speed is fast. There is no need to consider the structural design of brickwork. After the device is fully spliced, it is a complete structure with low construction difficulty, no need to use concrete, and little impact on the surrounding green areas. 2. The seepage pipes 2 in the soil layer are generally smaller in diameter in order to be distributed over a wider range, while the drainage pipe 52 needs to discharge multiple seepage pipes 2 and surface water at the same time. Therefore, the diameter of the drainage pipe 52 will be larger, so the drainage pipe needs to be lower. At present, when brickwork is performed, the position of the drainage pipe 52 may be far away from the seepage pipe 2. The water pipe 2 is at different distances, and the height position is easily changed during bricklaying, resulting in an incorrect height difference, which causes water accumulation in the overflow well. It is difficult to ensure that the height of the seepage pipe 2 is above the drainage pipe 52 during bricklaying, and it is difficult to ensure that the accumulated water in the soil layer is smoothly diverted during bricklaying. However, the present device can change the height position of the seepage pipe 2 by adjusting the angle of the reducer 3. Even if the seepage pipe 2 is slightly tilted upward, it can be sealed and plugged in, ensuring that each seepage pipe 2 is higher than the drainage pipe 52, and the seepage pipe 2 can also drain the accumulated water in the soil layer normally; 3. The ground water is collected by the water collecting bucket 1. Even if the accumulated water pipeline is broken, it is very convenient to replace it. The existing brick-built overflow well can only be rebuilt, which requires a large amount of work and is difficult to construct. It is also necessary to design each manhole cover to ensure that the size is the same to ensure the beauty of the green space. The present device is produced by mold production, with the same structure and beautiful structure.
[0047] When the utility model is in use, rainwater on the ground surface flows into the overflow inlet 11 at the top of the water collecting bucket 1 through the rainwater grate 4. When the overflow well needs to be checked, the rainwater grate 4 can be flipped open by the hinge 41, which is convenient for opening or closing and easy to use.
[0048] Water flows into the water collecting bucket 1 along the overflow inlet 11. When the drain pipe 1 of the overflow well is deeper and the height difference is larger, an extension pipe 12 can be added. The water will flow along the water collecting bucket 1 or the extension pipe 12 into the overflow pipe 5. The overflow pipe 5 is a three-way pipe with an opening at the top. Rainwater on the bottom flows along the overflow pipe 5 into the drain pipe 52. Because the seepage pipe 2 is at a higher height, the water flow in the water collecting bucket 1 will not flow into the seepage pipe 2.
[0049] The seepage pipe 2 is buried in the soil, and the water in the soil layer will flow into the seepage pipe 2 along the water permeable holes 21. The seepage pipe 2 is above the drainage pipe 2. The seepage pipe 2 is sealed and plugged with the inlet of the overflow pipe 5 through the reducer 3. The water inside the soil layer will flow into the overflow pipe 5 along the seepage pipe 2 and be discharged together through the drainage pipe 52. The seepage pipe 2 is at a high height, and the discharged water will not flow back.
[0050] Although the specific implementation methods of the present invention are described above, those skilled in the art should understand that the specific embodiments described are only illustrative and are not intended to limit the scope of the present invention. Equivalent modifications and changes made by those skilled in the art in accordance with the spirit of the present invention should be included in the scope of protection of the claims of the present invention.
