Description
Technical Field
[0001] This utility model relates to the technical field of rainwater and sewage drainage pipe fittings, and in particular to a roadbed sewage diversion pipe fitting. Background Technology
[0002] The underground drainage system of roads is used to transport rainwater and sewage. The existing underground drainage system of roads includes a main drainage pipe and multiple collection pipes. The main drainage pipe is buried underground, and multiple collection pipes are arranged along the main drainage pipe. The lower end is connected to the main drainage pipe, and the upper end extends to the ground. When it rains, rainwater and sewage on the ground enter the main drainage pipe through the inlet of the collection pipe. After the rainwater and sewage are collected in the main drainage pipe, they are transported to the sewage treatment plant for treatment.
[0003] The existing drainage system is prone to flooding when the main drainage pipe cannot drain water in time during periods of heavy rainfall, which also makes subsequent water treatment a heavy task. Utility Model Content
[0004] To address the shortcomings of existing drainage systems, such as easy water accumulation and heavy subsequent water treatment tasks, this utility model proposes a roadbed sewage diversion pipe fitting. Some rainwater and sewage are filtered in the main drainage pipe and then discharged through the branch pipe, reducing the water supply pressure of the main drainage pipe, preventing ground water accumulation, and reducing the subsequent water treatment tasks.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A roadbed sewage diversion pipe fitting includes a main drainage pipe, multiple branch pipes, and multiple water collection pipes. The main drainage pipe is buried in the roadbed. The multiple branch pipes and multiple water collection pipes are all installed along the main drainage pipe. One end of the branch pipe is connected to the left side of the main drainage pipe, and the other end of the branch pipe leads to a river. The lower end of the water collection pipe is connected to the right side of the main drainage pipe, and the upper end of the water collection pipe extends to the ground and is equipped with a filter cover. The sewage diversion pipe fitting also includes an insert plate. An upper slot is provided along the length direction on the upper side of the left inner wall of the main drainage pipe, and a lower slot is provided along the length direction on the lower side of the left inner wall of the main drainage pipe. The ends of the upper slot and the lower slot extend to the end of the main drainage pipe. The upper and lower sides of the insert plate are respectively embedded in the upper slot and the lower slot. The insert plate is provided with filter holes, and the diameter of the filter holes is smaller than the inner diameter of the branch pipe.
[0007] With the above setup, firstly, when rainfall is heavy, the branch pipe will divert some of the rainwater and sewage from the main drainage pipe, reducing the drainage pressure of the main drainage pipe and preventing water accumulation on the ground; secondly, the insert plate can filter garbage in rainwater and sewage, reducing river pollution; thirdly, the insert plate is installed through the lower slot and the upper slot, making it convenient to install and remove the insert plate.
[0008] Furthermore, the bottom of the main drain pipe is horizontal, and its cross-section is D-shaped.
[0009] The above settings increase the stability of the main drainage pipe.
[0010] Furthermore, the water collection pipe is L-shaped, consisting of a horizontal section and a vertical section. One end of the horizontal section is connected to the right side of the main drain pipe, and the other end of the horizontal section is connected to the lower end of the vertical section. A filter cover is installed at the upper end of the vertical section.
[0011] With the above setup, rainwater and sewage on the ground enter the main drainage pipe through the vertical and horizontal sections.
[0012] Furthermore, there is a circular arc transition between the horizontal and vertical segments.
[0013] The above settings reduce the resistance to the downward flow of rainwater and sewage.
[0014] Furthermore, the filter cover has a downward-extending flange on its edge. The filter cover covers the upper end of the water collection pipe, and the flange surrounds the water collection pipe. Several filter grooves are provided on the filter cover.
[0015] With the above setup, the flange allows the filter cover to be stably placed on the upper end of the water collection pipe, and the filter groove is used to block larger debris, thus playing a filtering role.
[0016] Furthermore, the insert plate is set as a rectangular flat plate, with the lower slot close to the left edge of the bottom of the main drain pipe, and the insert plate is vertically installed between the upper slot and the lower slot.
[0017] With the above setup, the insert plate is positioned close to the left side of the main drain pipe and the outlet of the branch pipe, leaving more space on the right side to facilitate the flow of rainwater and sewage in the main drain pipe.
[0018] Furthermore, the insert plate is set as an arc-shaped plate, with the outer side of the insert plate attached to the inner wall of the left side of the main drain pipe.
[0019] With the above settings, the space on the right side of the insert plate is further increased, providing more space for the flow of rainwater and sewage in the main drain pipe, making it more convenient for the main drain pipe to drain water.
[0020] Furthermore, the lower side of the horizontal section of the water collection pipe is flush with the bottom of the main drain pipe, and the lower side of the branch pipe is higher than the bottom of the main drain pipe. A boss is fixedly connected to the left side of the bottom of the main drain pipe along the length direction. A guide surface is provided on the upper side of the boss. The side of the guide surface away from the water collection pipe is inclined upward and has the aforementioned slot. A baffle surface is provided on the side of the boss near the water collection pipe. The lower side of the baffle surface extends to the bottom of the main drain pipe. The upper side of the baffle surface is inclined towards the water collection pipe and extends to the guide surface.
[0021] With the above settings, when the rainfall is small, after the rainwater and sewage enter the main drainage pipe through the collection pipe, the flow-blocking surface blocks the rainwater and sewage, preventing garbage in the rainwater and sewage from being washed onto the inlet plate, reducing the garbage on the inlet plate and preventing blockage; the inclined setting of the guide surface can prevent water accumulation on the upper side.

[0026] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.
[0027] like Figures 1 to 3 As shown, a roadbed sewage diversion pipe fitting includes a main drainage pipe 3, multiple branch pipes 4, and multiple water collection pipes 5. The main drainage pipe 3 is buried in the roadbed. The multiple branch pipes 4 and multiple water collection pipes 5 are all set along the main drainage pipe 3. One end of the branch pipe 4 is connected to the left side of the main drainage pipe 3, and the other end of the branch pipe 4 leads to a river. The lower end of the water collection pipe 5 is connected to the right side of the main drainage pipe 3, and the upper end of the water collection pipe 5 extends to the ground and is equipped with a filter cover 6. The sewage diversion pipe fitting also includes an insert plate 7. An upper slot 8 is provided on the upper side of the left inner wall of the main drainage pipe 3 along the length direction, and a lower slot 9 is provided on the lower side of the left inner wall of the main drainage pipe 3 along the length direction. The ends of the upper slot 8 and the lower slot 9 penetrate to the end of the main drainage pipe 3. The upper and lower sides of the insert plate 7 are respectively embedded in the upper slot 8 and the lower slot 9. A filter hole 10 is provided on the insert plate 7, and the diameter of the filter hole 10 is smaller than the inner diameter of the branch pipe 4.
[0028] With the above settings, firstly, when the rainfall is heavy, the branch pipe 4 will divert some of the rainwater and sewage in the main drainage pipe 3, reducing the drainage pressure of the main drainage pipe 3 and preventing water accumulation on the ground; secondly, the insert plate 7 can filter garbage in the rainwater and sewage, reducing river pollution; thirdly, the insert plate 7 is installed through the lower slot 9 and the upper slot 8, making it convenient to install and remove the insert plate 7.
[0029] When the sewage diversion pipe fitting of this application is used, rainwater and sewage on the ground enter the main drainage pipe 3 through the filter cover 6 and the water collection pipe 5. The filter cover 6 is used to filter rainwater and sewage on the ground and prevent large-volume garbage from entering the main drainage pipe 3 through the water collection pipe 5. After being filtered by the baffle plate 7, part of the rainwater and sewage in the main drainage pipe 3 is discharged into the river through the branch pipe 4. The remaining rainwater and sewage flow to the sewage treatment plant through the main drainage pipe 3. When the rainwater and sewage in the main drainage pipe 3 flows through the baffle plate 7, it can wash away the garbage on the surface of the baffle plate 7 and prevent it from entering the sewage treatment plant. Plate 7 is clogged; the filter hole 10 on the insert plate 7 of this application has a hole diameter of 10mm-15mm, specifically set to 13mm; the main drain pipe 3, branch pipe 4 and water collection pipe 5 are all made of PVC-U material, which has good pressure resistance, durability and weather resistance; the branch pipe 4 and water collection pipe 5 are welded to the left and right sides of the main drain pipe 3, which has good sealing performance; the insert plate 7 is made of stainless steel, which improves rust resistance; the insert plate 7 is inserted from the end of the main drain pipe 3 along the upper slot 8 and lower slot 9, which is very convenient for disassembly and assembly.
[0030] As one implementation method, the bottom of the main drain pipe 3 is horizontal, and its cross-section is D-shaped.
[0031] The above settings increase the stability of the main drain pipe 3.
[0032] As one implementation method, the water collection pipe 5 is L-shaped, which includes a horizontal section 51 and a vertical section 52. One end of the horizontal section 51 is connected to the right side of the main drain pipe 3, and the other end of the horizontal section 51 is connected to the lower end of the vertical section 52. A filter cover 6 is installed on the upper end of the vertical section 52.
[0033] With the above setup, rainwater and sewage from the ground enter the main drainage pipe 3 through the vertical section 52 and the horizontal section 51.
[0034] As one implementation method, there is a circular arc transition between the horizontal segment 51 and the vertical segment 52.
[0035] The above settings reduce the resistance to the downward flow of rainwater and sewage.
[0036] As one implementation, the filter cover 6 has a downwardly extending flange 11 on its edge. The filter cover 6 covers the upper end of the water collection pipe 5, the flange 11 surrounds the water collection pipe 5, and the filter cover 6 has several filter grooves 12.
[0037] With the above settings, the flange 11 allows the filter cover 6 to be stably placed on the upper end of the water collection pipe 5, and the filter groove 12 is used to block larger garbage and play a filtering role.
[0038] As one implementation, the insert plate 7 is set as a rectangular flat plate, the lower slot 9 is close to the left edge of the bottom of the main drain pipe 3, and the insert plate 7 is vertically installed between the upper slot 8 and the lower slot 9.
[0039] With the above arrangement, the insert plate 7 is close to the left side of the main drain pipe 3 and the opening of the branch pipe 4, leaving more space on the right side to facilitate the flow of rainwater and sewage in the main drain pipe 3.
[0040] In another embodiment, such as Figure 4 As shown, the insert plate 7 is set as an arc-shaped plate, and the outer side of the insert plate 7 is attached to the inner wall of the left side of the main drain pipe 3.
[0041] With the above settings, the space on the right side of the insert plate 7 is further increased, and the flow space of rainwater and sewage in the main drain pipe 3 is larger, making it more convenient for the main drain pipe 3 to drain water.
[0042] In one implementation, the lower side of the horizontal section 51 of the water collection pipe 5 is flush with the bottom of the main drain pipe 3, and the lower side of the branch pipe 4 is higher than the bottom of the main drain pipe 3. A boss 13 is fixedly connected to the left side of the bottom of the main drain pipe 3 along the length direction. A guide surface 15 is provided on the upper side of the boss 13. The side of the guide surface 15 away from the water collection pipe 5 is inclined upward and provided with the aforementioned lower slot 9. A flow-blocking surface 14 is provided on the side of the boss 13 close to the water collection pipe 5. The lower side of the flow-blocking surface 14 extends to the bottom of the main drain pipe 3, and the upper side of the flow-blocking surface 14 is inclined towards the water collection pipe 5 and extends to the guide surface 15.
[0043] With the above settings, when the rainfall is small, the rainwater and sewage enter the main drainage pipe 3 through the collection pipe 5, and the flow-blocking surface 14 blocks the rainwater and sewage, preventing garbage in the rainwater and sewage from being washed onto the insert plate 7, reducing the garbage on the insert plate 7, and preventing the insert plate 7 from being blocked; the guide surface 15 is set at an angle to prevent water accumulation on the upper side.
[0044] When the rainfall is low, the water level in the main drainage pipe 3 is low. After the rainwater and sewage on the ground enter the main drainage pipe 3 through the filter cover 6 and the water collection pipe 5, the flow-blocking surface 14 prevents the rainwater and sewage from directly washing onto the insert plate 7, reducing the garbage on the insert plate 7. The upper end of the flow-guiding surface 15 is flush with the lower inner wall of the branch pipe 4, and the flow-guiding surface 15 is inclined inward to prevent water accumulation on the upper side.
[0045] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
