Description

Technical Field

[0001] This utility model relates to the field of drainage pipe technology, and in particular to a high-efficiency and stable sponge city drainage pipe. Background Technology

[0002] Sponge cities, also known as "water-resilient cities," refer to cities that, like sponges, possess excellent resilience in adapting to environmental changes and responding to natural disasters caused by rainwater. Their core concept involves six measures—infiltration, retention, storage, purification, utilization, and drainage—to achieve the natural accumulation, infiltration, and purification of rainwater, thereby promoting the ecological, safe, and sustainable development of the urban water cycle system. Sponge city infiltration pipes have a simple and reasonable structure, are reusable, and have a long service life. They not only retain moisture, fertilizer, and water, but also prevent collapse and subsidence. Furthermore, infiltration pipes can be used in various terrains and locations, making them easy to install and use, environmentally friendly, and widely applicable in different fields.

[0003] In sponge city systems, infiltration pipes are typically buried underground to increase rainwater drainage and improve underground humidity. These pipes are usually in the form of flexible hoses with multiple holes, with the perforated side facing the ground. However, current technology using flexible hoses has low compressive strength, making them prone to swaying and displacement, which affects the installation. Furthermore, they are susceptible to deformation and damage after prolonged pressure. In addition, sediment can enter the pipes with the water flow, causing blockages and affecting the infiltration performance of the pipes.

[0004] To address this, we designed a high-efficiency and stable sponge city infiltration pipe. Utility Model Content

[0005] The purpose of this invention is to propose a high-efficiency and stable sponge city permeable pipe to solve the problems of low compressive strength and low permeability in existing technologies.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] High-efficiency and stable sponge city drainage pipe, including the pipe body, and also including;

[0008] The positioning component includes a support pad disposed at the bottom of the tube and limiting pads disposed on both sides of the top of the support pad;

[0009] The filter assembly includes metal rings disposed at both ends of the tube body, a screen disposed on the inner wall of the metal rings, and a fixing assembly disposed between the metal rings and the tube body.

[0010] Preferably, the tube body has an insertion body on both sides of its bottom, the top of the insertion body extends upward into the tube body, and the top of the support pad has a limiting ring that cooperates with the insertion body.

[0011] Preferably, the fixing assembly includes a bonding plate disposed at one end of the insert body located inside the tube, and a first insert block disposed on both sides of the bottom of the metal ring and cooperating with the bonding plate.

[0012] Preferably, the fixing component further includes a second insert block disposed on the top of the metal ring and insert strips disposed on both sides of the second insert block.

[0013] Preferably, the side wall of the bonding plate is provided with a first groove that mates with the first insert block, the end of the tube is provided with a second groove that mates with the second insert block, and the inner wall of the second groove is provided with an insertion groove that mates with the insertion strip.

[0014] Preferably, the tube body is made of PE rubber material.

[0015] Preferably, the pipe body is wrapped with two layers of geotextile, and buffer sand is filled between the two layers of geotextile.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. This utility model, through the setting of the positioning component, when the pipe body is pre-embedded, first places the pipe body on the support pad in the positioning component, and then fixes the pipe body on the top of the support pad through the setting of the insertion body and the limiting ring. The setting of the limiting pad can block and limit the two sides of the pipe body, thereby improving the stability of the pipe body and solving the problem that the pipe body is prone to shaking and displacement in the prior art, which affects the pre-embedding and laying.

[0018] 2. This utility model uses screens installed at both ends of the pipe to filter the water flowing through the pipe, preventing mud from entering the pipe and causing blockages that would affect the seepage function. In addition, the screens and pipe can be quickly installed and fixed by the attached plates, first inserts, second inserts, and insert strips. The operation is simple and saves time, thereby improving the installation speed of the pipe and screens.

[0019] 3. This utility model replaces the traditional soft permeable pipe with a rigid PE rubber pipe to improve the pipe's strength and effectively prevent deformation and damage caused by tools and equipment. At the same time, the geotextile placed on the outside of the pipe can filter and protect it, preventing impurities such as mud and sand from entering the pipe and affecting its permeability. Furthermore, the buffer sand filled in the geotextile can further enhance the pipe's compressive strength, thereby increasing the pipe's service life and reducing maintenance costs.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0027] Reference Figure 1 and Figure 2 The high-efficiency and stable sponge city infiltration pipe includes a pipe body 1, a positioning component and a filter component. The positioning component is set at the bottom of the pipe body 1 to fix and limit the pipe body 1. The filter component includes components set at both ends of the pipe body 1 to filter the water flowing through the pipe body 1.

[0028] When a seepage pipe is needed, it needs to be buried in the ground. First, a pre-buried pit is dug on the ground, the positioning component is placed in the pre-buried pit, and then the pipe body 1 is placed on the positioning component and fixed. At this time, when backfilling the pipe body 1, the pipe body 1 will not roll or shift, which makes it easier to pre-bury the pipe body 1. In addition, the filter component can filter the groundwater flowing into the pipe body 1 to prevent the mud and sand impurities mixed in the water from entering the pipe body 1 and causing the pipe to be blocked, thus affecting the seepage effect.

[0029] It should be noted that pipe body 1 is made of PE rubber material. The outer wall of pipe body 1 has seepage holes, and the outside of pipe body 1 is wrapped with two layers of geotextile, with buffer sand filling the space between the two layers. Replacing the traditional soft seepage pipe with a rigid PE rubber pipe greatly improves the strength of pipe body 1, effectively preventing damage from pressure deformation. The evenly spaced seepage holes around the PE rubber pipe ensure effective seepage. Simultaneously, the geotextile on the outside of pipe body 1 acts as a filter and protector, preventing impurities such as mud and sand from entering the pipe body and affecting seepage performance. The buffer sand filling the geotextile further enhances the pipe's compressive strength, thereby increasing the service life of pipe body 1 and reducing maintenance costs. Furthermore, this design not only accelerates the laying speed of pipe body 1 but also ensures long-term stable operation of the seepage pipe in complex environments through the synergistic effect of various components, demonstrating significant advantages in sponge city construction.

[0030] Specifically, such as Figure 2 , Figure 3 and Figure 4 As shown, in a preferred embodiment, based on the above method, the positioning component further includes a support pad 3 disposed at the bottom of the tube body 1 and limiting pads 4 disposed on both sides of the top of the support pad 3.

[0031] Both sides of the bottom of the tube body 1 are provided with insertion bodies 101. The top of the insertion body 101 extends upward into the inside of the tube body 1, and the top of the support pad 3 is provided with a limiting ring 104 that cooperates with the insertion body 101.

[0032] After the tube body 1 is placed on the support pad 3, the insertion body 101 at the bottom of the tube body 1 will be inserted into the limiting ring 104 at the top of the support pad 3, thereby fixing the tube body 1 and preventing the tube body 1 from rolling displacement, thus facilitating the filling of the tube body 1.

[0033] like Figure 2 , Figure 3 and Figure 5 As shown, in a preferred embodiment, based on the above method, the filter assembly further includes metal rings 2 disposed at both ends of the tube body 1, a screen 201 disposed on the inner wall of the metal rings 2, and a fixing assembly disposed between the metal rings 2 and the tube body 1.

[0034] Before pre-burying the pipe body 1, the metal ring 2 can be installed on both ends of the pipe body 1 through the fixing component. At this time, the screen 201 on the metal ring 2 can filter and block the mud and sand impurities in the water, preventing the mud and sand impurities from entering the pipe body 1 and causing pipe blockage and affecting water seepage.

[0035] Specifically, the fixing components include a bonding plate 102 disposed on one end of the insertion body 101 located inside the tube body 1, and a first insert block 202 disposed on both sides of the bottom of the metal ring 2 and cooperating with the bonding plate 102.

[0036] The fixing assembly also includes a second insert 203 disposed on the top of the metal ring 2 and insert strips 204 disposed on both sides of the second insert 203;

[0037] The side wall of the bonding plate 102 is provided with a first groove 105 that mates with the first insert 202, and the end of the tube body 1 is provided with a second groove 106 that mates with the second insert 203. The inner wall of the second groove 106 is provided with an insertion groove that mates with the insertion strip 204.

[0038] When it is necessary to install the metal ring 2 to both ends of the tube body 1, holes matching the insert body 101 need to be made at the bottom of both ends of the tube body 1. After inserting the insert body 101 into the hole, ensure that both ends have excess ends protruding from the hole. In order to improve the fit and fixing effect of the insert body 101 on the inner wall of the tube body 1, the bonding plate 102 is made of PE material and the side wall is arc-shaped to facilitate abutment against the inner wall of the tube body 1. Holes need to be made at both the bonding plate 102 and the insert body 101. After the holes of the bonding plate 102 and the holes of the insert body 101 are aligned, the plastic fastener 103 made of PE material is installed in the hole for threaded connection. Then, hot melt adhesive is applied around the bonding plate 102 using hot melt adhesive technology, so that the bonding plate 102 is properly secured. 2. Fixing the metal ring 2 to the pipe body 1 can effectively prevent the metal material from being immersed in water for a long time, which would cause rust and contaminate the water flow. Then, the metal ring 2 is pressed against the end of the pipe body 1, so that the first insert 202 on the side wall of the metal ring 2 is inserted into the first groove 105 inside the bonding plate 102, and the second insert 203 on the top of the metal ring 2 is inserted into the second groove 106 at the end of the pipe body 1. The insertion strip 204 on the side wall of the second insert 203 will deform under pressure. When the metal ring 2 is completely pressed against the end of the pipe body 1, the insertion strip 204 will be squeezed into the insertion groove. At this time, the insertion strip 204 rebounds and resets and is stuck inside the insertion strip, thereby completing the fixation of the metal ring 2. This makes it easier to install the screen 201 at the end of the pipe body 1 to filter impurities.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
