Description

Technical Field

[0001] The utility model relates to the technical field of drainage pipes, in particular to a municipal drainage pipe structure for urban and rural planning. Background Art

[0002] Drainage pipes are a particularly important part of municipal engineering. They are related to the discharge of urban precipitation, thus ensuring that urban roads and building facilities are not submerged. The discharge capacity of drainage pipes is the standard for testing municipal pipes. Drainage pipes refer to the system composed of pipes and ancillary facilities that collect and discharge sewage, wastewater and rainwater. Including trunk pipes, branch pipes and pipes leading to treatment plants, no matter whether they are built on the streets or anywhere else, as long as they are pipes that play a drainage role, they should be counted as drainage pipes. The inner wall of the underground drainage pipes in the existing urban and rural planning municipal drainage pipe structure is prone to accumulation of silt and debris. Long-term accumulation can easily cause drainage pipe blockage, which is not conducive to the discharge of rainwater in the rainy season. At the same time, the internal silt and debris are not convenient to clean. Therefore, we have introduced a new urban and rural planning municipal drainage pipe structure. Utility Model Content

[0003] The main purpose of the utility model is to provide a municipal drainage pipe structure for urban and rural planning, which can effectively solve the problems in the background technology.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] The drain pipe structure of claim 1, wherein the drain pipe has two outer surfaces, the first surface being provided with a groove, the second surface being provided with a groove for sliding the drain pipe upward, and the second surface being provided with a groove for sliding the drain pipe upward.

[0006] Preferably, the second filter screen is in a cone-shaped structure as a whole.

[0007] Preferably, the mesh diameter on the first filter screen is the same as the mesh diameter on the outer surface of the second filter screen.

[0008] Preferably, the four sliding blocks are distributed in a circular array with equal distances therebetween.

[0009] Preferably, the four sliding blocks correspond to the positions of the four sliding grooves respectively, and the first filter screen is slidably installed in the four sliding grooves through the sliding blocks.

[0010] Preferably, the pulling plate is movably installed inside the mounting groove, and the height of the pulling plate is consistent with the depth of the mounting groove.

[0011] Preferably, the diameter of the limiting plate is larger than the inner diameter of the through hole.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. Through the set drainage outlets, rainwater will carry debris and silt into the sewer tube through several drainage outlets. Since the surface of the second filter screen with a conical structure is inclined, the debris and silt will fall onto the first filter screen for accumulation, while the rainwater will fall through the mesh on the second filter screen into the underground pipeline for transportation and drainage, thus avoiding the influence of debris and silt on drainage;

[0014] 2. By pulling the pulling plate high, it is convenient to lift the drain manhole cover, and then manually pull the pulling handle, so that the sliding block can be used to slide to quickly take out the first filter screen and clean it. During the rising process of the first filter screen and the second filter screen, the scraper can easily scrape off the silt sticking to the inner surface of the sewer pipe tube, and finally drop it onto the first filter screen and be taken out for cleaning together, which is convenient for cleaning the inner wall. By covering the drain manhole cover on the sewer pipe tube, the height of the pulling plate is level with the depth of the installation groove after installation, avoiding the problem of the pulling plate height being too high to affect the road and vehicles.

[0023] See also Figure 1-4 , the utility model provides a technical solution:

[0024] A municipal drainage pipeline structure for urban and rural planning, comprising a sewer tube 1 and a first filter screen 6, wherein an underground pipeline 3 is arranged at the lower end of the sewer tube 1, a drainage well cover 2 is movably installed at the upper end of the sewer tube 1, four sliding grooves 4 are arranged on the inner surface of the sewer tube 1, four sliding blocks 5 are arranged on the outer surface of the first filter screen 6, a scraper 7 is arranged on the outer surface of the first filter screen 6, a second filter screen 8 is arranged on the upper end of the first filter screen 6, a pulling handle 9 is arranged on the upper end of the second filter screen 8, and a pull handle 9 is arranged on the upper end of the second filter screen 8. A limiting groove 10 is provided on the inner surface of the handle 9, and a plurality of drainage ports 11 are provided on the upper end of the drainage manhole cover 2. Installation grooves 12 are provided on the upper left and upper right parts of the drainage manhole cover 2. Through holes 13 are provided on the front and rear parts of the inner lower walls of the two installation grooves 12. Sliding rods 14 are slidably installed inside the four through holes 13. Limiting plates 15 are provided on the lower ends of the four sliding rods 14, and a pulling plate 16 is fixedly installed on the upper ends of the two adjacent sliding rods 14 in front and behind.

[0025] In this embodiment, the second filter screen 8 has an overall conical structure; the mesh diameter on the first filter screen 6 is the same as the mesh diameter on the outer surface of the second filter screen 8; the four sliding blocks 5 are distributed in an equidistant circular array; the four sliding blocks 5 correspond to the positions of the four sliding grooves 4 respectively, and the first filter screen 6 is slidably installed in the four sliding grooves 4 through the sliding blocks 5.

[0026] In this embodiment, the pulling plate 16 is movably installed inside the installation groove 12 , and the height of the pulling plate 16 is consistent with the depth of the installation groove 12 ; the diameter of the limiting plate 15 is larger than the inner diameter of the through hole 13 .

[0027] It should be noted that the utility model is a municipal drainage pipe structure for urban and rural planning. During use, the first filter screen 6 and the second filter screen 8 are conveniently installed in the sewer pipe tube 1 through the sliding block 5. On rainy days, rainwater will carry debris and sludge through a number of drainage ports 11 into the sewer pipe tube 1. Since the surface of the second filter screen 8 with a conical structure is inclined, the debris and sludge will fall onto the first filter screen 6 for accumulation, while the rainwater will fall into the underground pipe 3 through the mesh holes on the second filter screen 8 for transportation and drainage. Therefore, the debris and sludge will not affect the drainage. When too much debris is accumulated after long-term use, the pulling plate 16 can be pulled high to facilitate the drainage. The manhole cover 2 is lifted, and then the pulling handle 9 is manually pulled, so that the sliding block 5 can be used to slide and quickly remove the first filter screen 6 and the second filter screen 8 for cleaning. During the rising process of the first filter screen 6 and the second filter screen 8, the scraper 7 can easily scrape off the silt sticking to the inner surface of the sewer pipe tube 1, and finally drop it onto the first filter screen 8 and take it out for cleaning, so as to facilitate the cleaning of the inner wall. After the cleaning is completed, the cleaned first filter screen 6 and the second filter screen 8 are installed, and the drainage manhole cover 2 is covered on the sewer pipe tube 1. After installation, the height of the pulling plate 16 is level with the depth of the installation groove 12, so as to avoid the problem that the height of the pulling plate 16 is too high and affects the road and vehicles.
