Description

Technical Field

[0001] The utility model relates to the field of catch basins, in particular to a prefabricated catch basin. Background Art

[0002] As an important water conservancy facility, the catch basin plays a key role in the rainwater collection and drainage system. However, there are certain limitations in the design and application of traditional catch basins, especially in terms of terrain restrictions and efficient utilization of water resources. Traditional catch basins often require complex on-site construction and are difficult to flexibly adapt to different environmental requirements. Traditional prefabricated catch basins also often have a single function and are only used for collecting rainwater. In addition, during the rainwater collection process, traditional catch basins often lack an effective filtration mechanism, resulting in uneven quality of the collected rainwater. Summary of the Utility Model

[0003] The technical problem to be solved and the technical task proposed by the utility model are to improve and perfect the existing technical solution, and provide a prefabricated catch basin for the purpose of realizing the multi-functional application of water collection and waterlogging drainage. For this purpose, the utility model adopts the following technical solutions.

[0004] A prefabricated catch basin includes a hollow well body, a manhole cover located at the wellhead, and a well seat located at the bottom of the well. The side of the well body is provided with a waterlogging drainage port, a permeable water inlet, and a water outlet from top to bottom. The waterlogging drainage port is provided with an openable drainage cover; the waterlogging drainage port is larger than the permeable water inlet. Through the permeable water inlet and the water outlet, water collection and filtration of clean water can be carried out under normal use conditions. Through the waterlogging drainage port and the openable drainage cover, in extreme weather conditions such as heavy rain or floods, waterlogging can be quickly drained, accelerating the drainage, enabling the catch basin to not only collect water and provide relatively clean water but also have the function of waterlogging drainage, realizing the multi-functional application of water collection, filtration of clean water, and waterlogging drainage of the catch basin. The waterlogging drainage port being larger than the permeable water inlet can ensure that the water drainage volume is greater than the water inlet volume, reducing the probability that the water volume in the catch basin exceeds the capacity and flushing out from the manhole cover, avoiding damage to the catch basin.

[0005] As a preferred technical means: The well body is provided with a plurality of permeable water inlets, and the permeable water inlets are connected to permeable water inlet pipes to obtain external water sources located under the permeable filtration layer. Since water sources can enter the well body from multiple water inlets, even if a certain permeable water inlet or permeable water inlet pipe fails, other water inlets and pipes can still continue to work. This structure improves the stability and reliability of the system, ensures the continuous supply of water resources, and improves the collection efficiency of water sources, ensuring the full utilization of water resources.

[0006] As a preferred technical means: Multiple said infiltration water inlets are distributed in different directions of the well body. By setting infiltration water inlets in different directions, the catch basin can more comprehensively cover the surrounding rainwater collection area, effectively enhancing the collection capacity of the catch basin and better improving the collection efficiency of water sources.

[0007] As a preferred technical means: The said infiltration water inlet pipe is provided with a bend, forming a pipeline with a higher inner part and a lower outer part. This structure makes the water infiltration point lower, and since rainwater infiltrates from the ground from low to high, it can effectively reduce the sediment entering the infiltration water inlet pipe, and because the water collection point is lower, it is easier to collect the infiltrated rainwater.

[0008] As a preferred technical means: Three infiltration water inlet pipes are provided on the said well body, and the horizontal interval between adjacent infiltration water inlet pipes is 60°. Setting three infiltration water inlets with an interval of 60° distribution, the quantity and position are reasonably optimized. Compared with more infiltration water inlets with a larger angular pitch, the infiltration range and infiltration pressure will not be dispersed, resulting in a reduction in the underground infiltration pressure, and it can more effectively maintain the water inlet speed and efficiency of underground infiltration.

[0009] As a preferred technical means: The said well cover is provided with a transparent observation window, or the well cover is a transparent well cover. The well cover is provided with a transparent observation window or made of transparent material, enabling the staff to directly monitor the water level and water quality in the well and the situation of the well, facilitating timely treatment, maintenance and servicing.

[0010] As a preferred technical means: The said well body is made of reinforced concrete or stainless steel. Making the well body with high-quality materials such as reinforced concrete or stainless steel ensures the durability of the catch basin and enables it to adapt to various harsh environments.

[0011] As a preferred technical means: The said well body, well cover and well seat are independent components. Manufacturing the well body, well cover and well seat into independent components, on the one hand, reduces the complexity of a single component and the volume and weight of a single component, facilitating manufacturing, storage, transportation and installation, and also facilitating maintenance and replacement. Only the damaged components need to be maintained or replaced, reducing the maintenance cost.

[0012] As a preferred technical means: The said drainage outlet is opposite to the water storage area to drain water in time when the water level is too high. When the water level in the catch basin is higher than the drainage outlet, it automatically drains into the water storage area from the drainage outlet. On the one hand, it can reduce the amount of water in the catch basin, timely drain the excess water, and prevent excessive water accumulation in the catch basin. On the other hand, when the rainfall does not cause waterlogging, the water drained from the drainage outlet can be collected again through the water storage area and will not be wasted, effectively slowing down the emptying time of the underground water body and effectively enhancing the balance ability of the underground water body.

[0013] As a preferred technical measure: the permeable water inlet pipe is provided with a filter screen assembly, which can effectively filter out impurities and pollutants in rainwater, ensuring the cleanliness and safety of the collected rainwater quality.

[0014] Beneficial effects: It can have the ability of water collection, providing clean filtered water outlet and waterlogging drainage at the same time, preventing the water accumulation in the catch well from being too much and causing damage to the catch well, and realizing the multi-functional application of the catch well.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The technical solution of the present utility model will be further described in detail below with reference to the accompanying drawings of the specification.

[0019] In the description of the present utility model, it should be understood that in terms of terms, if there are terms such as "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., the orientation or positional relationship indicated is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Since the disclosed embodiments of the present utility model can be arranged in different directions, these terms indicating directions should only be regarded as explanations and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to the directions opposite to or consistent with the gravity direction.

[0020] As Figure 1 、 2 shown, a prefabricated catch well includes a hollow well body 2, a well cover 3 located at the wellhead and a well seat 8 located at the bottom of the well. The catch well is prefabricated in a factory. The side of the well body 2 is provided with a waterlogging drainage port 5, a permeable water inlet 4 and a water outlet 1 from top to bottom. The waterlogging drainage port 5 is provided with an openable waterlogging drainage cover 11; the waterlogging drainage port 5 is larger than the permeable water inlet 4.

[0021] To achieve a relatively high collection efficiency of water sources, three infiltration inlets 4 are provided on the well body 2. The three infiltration inlets 4 are connected to three infiltration inlet pipes 10 to obtain external water sources located under the infiltration filtration layer, and the horizontal interval between adjacent infiltration inlet pipes 10 is 60°. Since water sources can enter the well body 2 from multiple inlets, even if a certain infiltration inlet 4 or infiltration inlet pipe 10 fails, other inlets and pipes can still continue to work. This structure improves the stability and reliability of the system, ensures the continuous supply of water resources, improves the collection efficiency of water sources, and ensures the full utilization of water resources. By setting infiltration inlets 4 in different orientations, the catch basin can more comprehensively cover the surrounding rainwater collection area, effectively enhancing the collection capacity of the catch basin and better improving the collection efficiency of water sources. The reasonably optimized number and position of inlets can maintain a relatively high seepage pressure and provide better seepage efficiency.

[0022] To collect the infiltrated rainwater more easily, the infiltration inlet pipe 10 is provided with bends to form a pipeline with a higher inner part and a lower outer part. This structure makes the water infiltration point lower, and since rainwater infiltrates from the ground from low to high, it can effectively reduce the ability of sediment to enter the infiltration inlet pipe 10, and because the water collection point is lower, it is easier to collect the infiltrated rainwater.

[0023] For the convenience of observation, the manhole cover 3 is provided with a transparent observation window, or the manhole cover 3 is a transparent manhole cover. The manhole cover 3 is provided with a transparent observation window or made of transparent material, enabling the staff to directly monitor the water level, water quality and the situation of the well inside, facilitating timely treatment, maintenance and servicing.

[0024] To ensure the durability of the catch basin, the well body 2 is made of reinforced concrete or stainless steel. Making the well body 2 with high-quality materials such as reinforced concrete or stainless steel ensures the durability of the catch basin and enables it to adapt to various harsh environments.

[0025] To facilitate manufacturing, storage and transportation, the well body 2, the manhole cover 3 and the well seat 8 are independent components. Making the well body 2, the manhole cover 3 and the well seat 8 into independent components reduces the complexity of a single component and the volume and weight of a single component on the one hand, facilitating manufacturing, storage, transportation and installation, and also facilitating maintenance and replacement. Only the damaged components need to be maintained or replaced, reducing the maintenance cost.

[0026] In order to improve the balance capacity of the groundwater body, the drainage outlet 5 is opposite to the water storage area 6 so that water can be discharged in time when the water level is too high. When the water level in the water collection well is higher than the drainage outlet 5, it is automatically discharged from the drainage outlet 5 into the water storage area 6. On the one hand, the amount of water in the water collection well can be reduced, and the excess water can be discharged in time to prevent excessive water accumulation in the water storage area 6. On the other hand, when the rainfall does not cause waterlogging, the water discharged from the drainage outlet 5 can be collected again through the water storage area 6 and will not be wasted, which can effectively slow down the emptying time of the groundwater body and effectively improve the balance capacity of the groundwater body.

[0027] In order to filter out impurities and pollutants in the rainwater, the infiltration water inlet pipe 10 is provided with a filter assembly, which can effectively filter out impurities and pollutants in the rainwater, ensuring that the collected rainwater is clean and safe.

[0028] Taking the stepped topography as an example, the various components of the water collection well are prefabricated in the factory and assembled and installed on site. During installation, a favorable terrain is selected first, the water collection well base is prefabricated and installed, the water collection well outlet pipe 9 and the infiltration water inlet pipe 10 are installed and fixed firmly, and the multi-layer infiltration filter layer 7 is arranged and installed according to the terrain and the position of the infiltration water inlet pipe 10. The three infiltration water inlet pipes 10 face the side of the low-lying water storage area 6, and the three infiltration water inlet pipes 10 adopt a 90-degree inverted L-shaped bend pipe. The vertical pipe mouth of the infiltration water inlet pipe 10 is downward, and the horizontal pipe mouth of the infiltration water inlet pipe 10 is connected to the water collection well. The vertical pipe mouth is provided with a filter mesh assembly, the water outlet 1 is connected to the water outlet pipe 9, and the drainage outlet 5 is located above the three infiltration water inlet pipes 10. The water outlet pipe 9 faces the low-lying side. When it rains, rainwater is collected from all over to the low-lying water storage area 6. The rainwater passes through multiple layers of infiltration filtration areas and is collected into the water collection well through the infiltration water inlet pipe 10. The clean water then flows from the water collection well into the clean water pool through the water outlet 1.

[0029] When the rainfall reaches a certain amount and the amount of water collected in the water collection well exceeds the drainage outlet 5, the drainage cover 11 automatically opens under the water pressure in the water collection well, and the drainage outlet 5 discharges the water in the water collection well to the water storage area 6. On the one hand, it can reduce the amount of water in the water collection well and discharge excess water in time to prevent excessive water accumulation in the water collection well. On the other hand, when the rainfall does not cause waterlogging, the water discharged from the drainage outlet 5 can be collected again through the water storage area 6 and will not be wasted. It can effectively slow down the drainage time of the groundwater body and effectively improve the balance capacity of the groundwater body.

[0030] When severe rainfall occurs, the water collecting well cover 3 is opened, and the excess water in the water collecting well exceeding the height of the water collecting well is discharged from the wellhead to avoid damaging the water collecting well.

[0031] Water can be collected and filtered water can be cleaned under normal use conditions through the infiltration inlet 4 and the outlet 1, and the drainage outlet 5 can re-drain the excess water in the catch well into the water storage area 6, which can effectively delay the retention time of water in the water storage area 6, make better use of rainwater, and has a compensatory effect on the groundwater body near the water storage area 6, better maintaining the balance of the groundwater body. Through the cooperation of the drainage outlet 5 and the drain cover 11 that can be opened, in extreme weather conditions such as heavy rain or floods, drainage can be carried out quickly, accelerating drainage, enabling the catch well to collect water and provide relatively clean water while having the function of drainage, realizing the multi-functional application of the catch well, and effectively providing clean water and reducing the damage to the catch well caused by excessive water volume.

[0032] The above Figure 1 、 2 A prefabricated catch well shown above is a specific embodiment of the present invention, which has already reflected the substantial features and progress of the present invention. According to actual use needs, under the inspiration of the present invention, equivalent modifications can be made to its shape, structure, etc., and all are within the protection scope of this solution.
