Description

Technical Field

[0001] This utility model relates to the technical field of pressure reducing devices, specifically a novel water drainage pressure reducing device. Background Technology

[0002] When the groundwater level rises to a certain level, potentially causing serious damage to the strength of the roadbed, pavement, or slope stability, measures need to be taken to drain the groundwater. For example, during the construction of urban roadbeds, a high groundwater level may cause the roadbed soil to be excessively moist, thereby affecting the stability and strength of the roadbed.

[0003] At this point, a drainage system is needed to drain the groundwater to ensure the safety and stability of the road. In existing technologies, to ensure a stable discharge of water, filters are used to remove impurities. However, these filters have simple structures and are prone to wear and tear after prolonged use, reducing their filtration efficiency and making them unable to effectively intercept suspended solids or impurities. Furthermore, when groundwater enters the drainage system, the lack of an effective pressure-reducing mechanism leads to excessively high flow velocity and large pressure fluctuations, which may impact subsequent pipe networks and pumping systems, potentially causing malfunctions. To address the shortcomings of existing technologies, this invention provides a novel water drainage and pressure-reducing device to solve the aforementioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a novel water drainage and pressure reduction device that deeply integrates the reverse filter layer with the pressure reduction function. The reverse filter structure is simple, has high structural strength, and a long service life. At the same time, the multi-stage pressure reduction channel design enables the device to achieve efficient reverse filtration and pressure reduction functions within a limited space, improving the device's compactness and reliability. It effectively reduces pressure fluctuations when groundwater enters the drainage system, minimizing the impact on subsequent pipe networks and pumping systems.

[0012] A base layer is set inside the filter structure, and the base layer is made of a corrosion-resistant and high-strength base material as support;

[0013] A filter layer is disposed on the side of the base layer. The filter layer uses multiple layers of filter materials with different particle sizes to intercept suspended solids, impurities and fine particles in the water.

[0014] A reinforcing layer is provided on the side of the filter layer. The reinforcing layer adds reinforcing fiber mesh at the filter layer position to improve the tensile strength and deformation resistance of the overall reverse filtration structure.

[0015] Preferably, the first pressure relief channel is provided with multiple sets of first pressure relief plates, and the first set of first pressure relief plates has a first gradient pressure relief hole at the axis of the multiple sets of first pressure relief plates.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] This application provides a novel water drainage and pressure reduction device, which solves the problems in the prior art where the filter screen structure of the drainage system is simple, easily wears down after long-term use, reduces the filtration effect, and cannot effectively intercept suspended solids or impurities. At the same time, when groundwater enters the drainage system, due to the lack of an effective pressure reduction mechanism, the water flow speed is too fast and the pressure fluctuation is large, which may impact the subsequent pipe network and pumping system, or even cause failure.

[0030] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

The base material is made of high-density polyethylene or polypropylene to ensure the structural stability and durability of the device.

[0040] The filter layer 52 is located on the side of the base layer 51. The filter layer 52 uses multiple layers of filter media with different particle sizes to intercept suspended solids, impurities and fine particles in the water. The filter media are selected from sand, gravel or activated carbon particles of different particle sizes.

[0041] The reinforcing layer 53 is located on the side of the filter layer 52. The reinforcing layer 53 adds a reinforcing fiber mesh to the filter layer 52 to improve the tensile strength and deformation resistance of the overall reverse filter structure 5, ensuring that the device can maintain a stable filtration effect under long-term water flow.

[0042] The reverse filter structure 5 has a simple structure, high structural strength, and long service life. It can not only filter out suspended solids, impurities, and fine particles in the water, but also further reduce water pressure by resisting water flow, thus improving the water pressure reduction effect of the device.

[0043] The first pressure relief channel 2 is provided with multiple sets of first pressure relief plates 21, and a first gradient pressure relief hole 22 is opened at the axis of the multiple sets of first pressure relief plates 21.

The first pressure-reducing plates 21 and multi-stage pressure-reducing plates 41 respectively form first gradient pressure-reducing holes 22 and multi-stage gradient pressure-reducing holes 42 to provide multi-stage pressure reduction for water flow. The pressure reduction effect is good, enabling the device to achieve efficient reverse filtration and pressure reduction functions in a limited space. It improves the compactness and reliability of the device, effectively reduces pressure fluctuations when groundwater enters the drainage system, and reduces the impact on subsequent pipe networks and pumping systems.
