Description

Technical Field

[0001] This invention belongs to the field of drainage construction technology, specifically relating to a method for constructing municipal drainage pipe networks. Background Technology

[0002] Since the beginning of the new century, with the rapid improvement of my country's national economic level and the continuous acceleration of the modernization process of Chinese cities, drainage pipe networks, as a very important infrastructure in the process of urban modernization, are also a core component of the entire urban drainage system. The construction of drainage pipe networks has received increasing attention. Municipal drainage pipes refer to rainwater and sewage pipes under municipal roads, commonly known as "sewage pipes." In engineering, they are usually called municipal drainage pipes. Municipal drainage pipes can be divided into sewage pipes and rainwater pipes. Different drainage pipes are interconnected and intertwine to form a network structure, which is called a drainage pipe network. In the construction of drainage pipe networks, the pipe connection method often uses socket joints.

[0003] Currently, when constructing drainage pipe networks, the general process involves excavating trenches according to design drawings, followed by pipe network installation, and finally backfilling. When laying pipes in the trench, it is often necessary to connect sections of pipe together. When laying long pipes, and then connecting two pipe sections, the pipe ends are usually manually lifted to a certain height to facilitate the connection and installation. Due to the weight of the pipes, it is very strenuous for workers to lift them for a long time, resulting in high labor intensity and the risk of shaking, which affects the accuracy of the installation.

[0004] Therefore, a new construction method for municipal drainage pipe networks is needed to address the problems of manual lifting of pipe ends to a certain height, which is laborious, physically demanding, and prone to shaking, affecting installation accuracy. Summary of the Invention

[0005] The purpose of this invention is to provide a method for constructing municipal drainage pipe networks to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a method for constructing municipal drainage pipe networks, wherein the drainage pipe network construction method is based on a base slab and includes the following steps:

[0007] S1. First, insert the set multiple pins into the soil to pre-position the base plate, so that the threaded rod b can be inserted into the soil.

[0008] S2. By holding and rotating the handle bar b, the handle bar b drives the threaded bar b to rotate and deeply insert it into the soil, thereby quickly fixing the base plate to the ground;

[0009] S3. Place the pipe end to be connected into the concave seat, and rotate the joint plate a. The joint plate a drives the threaded rod a to rotate. At the same time, the movement of the clamping plate is guided and limited by the two guide pins, so that the rotating threaded rod a pushes the clamping plate to move closer to the limiting plate, thereby clamping and fixing the pipe end between the clamping plate and the limiting plate.

[0010] S4. By holding and rotating the handle rod a, the handle rod a drives the outer ring plate to rotate, and the outer ring plate drives the nut sleeve to rotate, thereby adjusting the height of the outer ring plate. The outer ring plate pushes the outer sleeve to move upward, thereby conveniently adjusting the height of the concave seat, and then adjusting the height of the pipe port inside the concave seat for installation.

[0011] It should be noted that the solution includes insertion and fixing components at both ends of the base plate, a threaded rod c fixed at the center of the top side of the base plate, an outer sleeve fitted over the threaded rod c, a concave seat fixed at the top of the outer sleeve, an adjustment component between the threaded rod c and the outer sleeve, a connecting rod fixed on the inner wall of one end of the concave seat, a limit plate fixed on the end of the connecting rod near the center of the concave seat, a clamping component that cooperates with the limit plate on the other end of the concave seat, a handle fixed at the top of the concave seat, and a rubber sleeve c fitted on the surface of the handle.

[0012] It should be noted in the solution that the adjusting component includes a nut sleeve that is threaded to the side of the threaded rod c, an outer ring plate is fixed to the outside of the nut sleeve, the bottom side of the outer sleeve fits against the top side of the outer sleeve, a handle rod a is fixed to the outer surface of the outer ring plate, two symmetrically distributed sliding grooves are opened on the side of the outer sleeve, and a protruding rod that slides and adapts to the sliding grooves is fixed to the top of the threaded rod c.

[0013] It is worth noting that a boss located on the bottom periphery of the outer sleeve is fixed on the top side of the outer sleeve plate, and a rubber sleeve a is fitted onto the surface of the handle rod a.

[0014] Furthermore, it should be noted that the clamping assembly includes a threaded rod a that is threadedly connected to the side wall of the concave seat away from the limiting plate. A clamping plate is fixed to the end of the threaded rod a near the limiting plate. A guide post that slides through the side wall of the concave seat is fixed to the side of the clamping plate away from the limiting plate. There are two guide posts, which are symmetrically distributed. A connector plate a is fixed to the end of the threaded rod a away from the limiting plate.

[0015] In a preferred embodiment, a handle rod b is fixed to the top side of the connector plate a, and a soft rubber sleeve is fitted onto the surface of the handle rod b.

[0016] In a preferred embodiment, rubber pads are fixedly attached to the sides of the clamping plate and the limiting plate that are close to each other, and the sides of the clamping plate and the limiting plate that are close to each other are all set as arc surfaces.

[0017] In a preferred embodiment, the insertion assembly includes a threaded rod b located at one end of the base plate and threadedly connected to the base plate, a connector plate b fixed to the top end of the threaded rod b, a handle rod b fixed to the side of the connector plate b, and a pointed end provided at the bottom end of the threaded rod b.

[0018] In a preferred embodiment, a rubber sleeve b is fitted onto the surface of the handle rod b, and a base is fixed to the bottom end of the threaded rod c, the base being fixed to the base plate by a plurality of screws.

[0019] In a preferred embodiment, a plurality of pins are fixed on the bottom side of the base plate, and the plurality of pins are arranged symmetrically.

[0020] Compared with the prior art, the municipal drainage pipe network construction method provided by the present invention has at least the following beneficial effects:

[0021] (1) The base plate is quickly fixed to the ground by inserting the fixing component into the soil, which effectively improves the stability of the base plate on the ground, thereby improving the stability of the pipe clamped in the concave seat. The threaded rod c, the outer sleeve and the concave seat are placed vertically, and the pipe end to be connected is placed in the concave seat. The pipe end is clamped and fixed in the concave seat by the clamping component, thereby avoiding shaking when the pipe is connected. This eliminates the need for manual operation of holding the pipe end for connection, making the pipe end connection installation more labor-saving and effectively improving the overall efficiency of pipe connection installation.

[0022] (2) The outer sleeve is moved upward by adjusting the component, thereby conveniently adjusting the height of the concave seat, and then adjusting the height of the pipe port inside the concave seat, adjusting the pipe port to a height suitable for manual installation, so that the pipe port can be connected and installed manually.

[0033] The present invention will be further described below with reference to embodiments.

[0034] Please see Figure 1-9 This invention provides a method for constructing a municipal drainage pipe network. The method is based on a base slab 13 and includes the following steps:

[0035] S1. First, insert the multiple pins 12 into the soil to pre-position the base plate 13, so that the threaded rod b301 can be inserted into the soil.

[0036] S2. By holding and rotating the handle rod c303, the handle rod c303 drives the threaded rod b301 to rotate and deeply insert into the soil, thereby quickly fixing the base plate 13 to the ground;

[0037] S3. Place the pipe end to be connected into the concave seat 4, and rotate the joint plate a202. The joint plate a202 drives the threaded rod a201 to rotate. At the same time, the movement of the clamping plate 205 is guided and limited by the two guide pins 204, so that the rotating threaded rod a201 pushes the clamping plate 205 to move closer to the limiting plate 9, thereby clamping and fixing the pipe end between the clamping plate 205 and the limiting plate 9.

[0038] S4. By holding and rotating the handle rod a104, the handle rod a104 drives the outer ring plate 101 to rotate, and the outer ring plate 101 drives the nut sleeve 102 to rotate, thereby adjusting the height of the outer ring plate 101. The outer ring plate 101 pushes the outer sleeve 10 to move upward, thereby conveniently adjusting the height of the concave seat 4, and then adjusting the height of the internal pipe port of the concave seat 4 for installation.

[0039] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the base plate 13 is equipped with insertion components 3 at both ends, and a threaded rod c5 is fixed at the center of the top side of the base plate 13. An outer sleeve 10 is fitted over the threaded rod c5, and a concave seat 4 is fixed to the top of the outer sleeve 10. An adjustment component 1 is provided between the threaded rod c5 and the outer sleeve 10. A connecting rod 14 is fixed to the inner wall of one end of the concave seat 4, and a limiting plate 9 is fixed to the end of the connecting rod 14 near the center of the concave seat 4. A clamping component 2 that cooperates with the limiting plate 9 is provided on the other end of the concave seat 4. A handle 6 is fixed to the top of the concave seat 4, and a rubber sleeve c7 is fitted onto the surface of the handle 6. During the pipeline laying process, the insertion components 3 are first screwed into the soil, thereby quickly fixing the base plate 13 to the ground, effectively improving... The stability of the base plate 13 fixed to the ground improves the stability of the pipe clamped inside the concave seat 4, allowing the threaded rod c5, outer sleeve 10, and concave seat 4 to be placed vertically. Then, the pipe end to be connected is placed inside the concave seat 4, and the pipe end is clamped and fixed inside the concave seat 4 by the clamping component 2, thereby avoiding shaking during pipe connection and eliminating the need for manual operation of the pipe port. This makes pipe port connection and installation more labor-saving and effectively improves the overall efficiency of pipe connection and installation. By adjusting the component 1 to push the outer sleeve 10 upward, the height of the concave seat 4 can be easily adjusted, thereby adjusting the height of the pipe port inside the concave seat 4. The pipe port is adjusted to a height suitable for manual installation, making it convenient for manual connection and installation of the pipe port.

[0040] Further as Figure 1 , Figure 2 and Figure 4As shown, it is worth noting that the adjusting assembly 1 includes a nut sleeve 102 threadedly connected to the side of the threaded rod c5. An outer ring plate 101 is fixed to the outside of the nut sleeve 102. The bottom side of the outer sleeve 10 fits against the top side of the outer sleeve 10. A handle rod a104 is fixed to the outer surface of the outer ring plate 101. Two symmetrically distributed sliding grooves 106 are opened on the side of the outer sleeve 10. A protruding rod 107 that slides and adapts to the sliding grooves 106 is fixed to the top of the threaded rod c5. In actual operation, by holding and rotating the handle rod a104, the handle rod a104 drives the outer ring plate 101 to rotate. The outer ring plate 101 drives the nut sleeve 102 to rotate, thereby adjusting the height of the outer ring plate 101. The outer ring plate 101 pushes the outer sleeve 10 to move upward, thereby conveniently adjusting the height of the concave seat 4, and then adjusting the height of the pipe port inside the concave seat 4, adjusting the pipe port to a height suitable for manual installation, so as to facilitate manual docking and installation of the pipe port.

[0041] Further as Figure 7 As shown, it is worth noting that a boss 103 located on the bottom periphery of the outer sleeve 10 is fixed on the top side of the outer sleeve plate 101, and a rubber sleeve a105 is fitted onto the surface of the handle rod a104. In actual operation, the rubber sleeve a105 effectively increases the friction when gripping and rotating the handle rod a104, preventing slippage.

[0042] Further as Figure 1 , Figure 6 and Figure 8 As shown, it is worth noting that the clamping assembly 2 includes a threaded rod a201 that is threadedly connected to the side wall of the concave seat 4 away from the limiting plate 9. A clamping plate 205 is fixed to the end of the threaded rod a201 near the limiting plate 9. A guide post 204 that slides through the side wall of the concave seat 4 is fixed to the side of the clamping plate 205 away from the limiting plate 9. There are two guide posts 204, which are symmetrically distributed. A connector plate a202 is fixed to the end of the threaded rod a201 away from the limiting plate 9. In actual operation, the pipe end to be connected is placed into the concave seat 4. Internally, by rotating the joint plate a202, the joint plate a202 drives the threaded rod a201 to rotate. At the same time, the movement of the clamping plate 205 is guided and limited by the two guide posts 204. This causes the rotating threaded rod a201 to push the clamping plate 205 towards the limiting plate 9, thereby clamping and fixing the pipe end between the clamping plate 205 and the limiting plate 9. This avoids shaking during pipe connection, eliminates the need for manual operation of holding the pipe end for connection, and makes pipe connection installation more labor-saving, effectively improving the overall efficiency of pipe connection installation.

[0043] Further as Figure 8As shown, it is worth noting that a handle rod b203 is fixed on the top side of the connector plate a202, and a soft rubber sleeve is fitted onto the surface of the handle rod b203. In actual operation, the connector plate a202 is rotated by holding the handle rod b203. The handle rod b203 has a long lever arm, making operation easier.

[0044] Further as Figure 8 As shown, it is worth noting that rubber pads 206 are fixedly attached to the sides of the clamping plate 205 and the limiting plate 9 that are close to each other, and the sides of the clamping plate 205 and the limiting plate 9 that are close to each other are all set as arc surfaces; in actual operation, the rubber pads 206 effectively increase the friction force of the clamping plate 205 and the limiting plate 9 when clamping the outer wall of the pipe, thereby improving the stability of the clamping and fixing of the pipe end.

[0045] Further as Figure 1 , Figure 3 and Figure 5 As shown, it is worth noting that the insertion assembly 3 includes a threaded rod b301 located at one end of the base plate 13 and threadedly connected to the base plate 13. A connector plate b302 is fixed to the top of the threaded rod b301, and a handle rod c303 is fixed to the side of the connector plate b302. A pointed tip 305 is provided at the bottom end of the threaded rod b301. During the pipeline laying process, the handle rod c303 is first held and rotated. The handle rod c303 drives the threaded rod b301 to rotate and deeply insert into the soil, thereby quickly fixing the base plate 13 to the ground, effectively improving the stability of the base plate 13 fixed to the ground, and thus improving the stability of the pipeline clamped and placed inside the concave seat 4, so that the threaded rod c5, the outer sleeve 10 and the concave seat 4 can be placed vertically.

[0046] This solution includes the following working process: During pipeline laying, the handle c303 is first rotated by holding and rotating the handle c303, which drives the threaded rod b301 to rotate deeply into the soil, thereby quickly fixing the base plate 13 to the ground. The pipe end to be connected is placed inside the concave seat 4, and the joint plate a202 is rotated by rotating the joint plate a202, which drives the threaded rod a201 to rotate. At the same time, the movement of the clamping plate 205 is guided and limited by the two guide posts 204, so that the rotating threaded rod a201 pushes the clamping plate 205. Move towards the limiting plate 9 to clamp and fix the pipe end between the clamping plate 205 and the limiting plate 9. By holding and rotating the handle rod a104, the handle rod a104 drives the outer ring plate 101 to rotate, and the outer ring plate 101 drives the nut sleeve 102 to rotate, thereby adjusting the height of the outer ring plate 101. The outer ring plate 101 pushes the outer sleeve 10 to move upward, thereby conveniently adjusting the height of the concave seat 4, and then adjusting the height of the pipe port inside the concave seat 4, adjusting the pipe port to a height suitable for manual installation.

[0047] Further as Figure 1 , Figure 3 and Figure 5 As shown, it is worth noting that a rubber sleeve b304 is fitted onto the surface of the handle c303, and a base 11 is fixed to the bottom end of the threaded rod c5. The base 11 is fixed to the base plate 13 by multiple screws. In actual operation, the rubber sleeve b304 effectively increases the friction when gripping and rotating the handle c303, making operation more convenient.

[0048] Further as Figure 1 As shown, it is worth noting that a pin 12 is fixed on the bottom side of the base plate 13. There are multiple pins 12, and the multiple pins 12 are symmetrically distributed. In actual operation, the base plate 13 is pre-positioned by inserting the multiple pins 12 into the soil, so that the threaded rod b301 can be inserted into the soil.

[0049] In summary: By screwing the insertion assembly 3 into the soil, the base plate 13 is quickly fixed to the ground, effectively improving the stability of the base plate 13 on the ground. This, in turn, improves the stability of the pipe clamped inside the concave seat 4, allowing the threaded rod c5, outer sleeve 10, and concave seat 4 to be placed vertically. Then, the pipe end to be connected is placed inside the concave seat 4, and the clamping assembly 2 clamps and fixes the pipe end inside the concave seat 4, thus avoiding shaking during pipe connection and eliminating the need for manual operation of the pipe port. This makes pipe port connection and installation more labor-saving and effectively improves the overall efficiency of pipe connection and installation. By adjusting the assembly 1 to push the outer sleeve 10 upward, the height of the concave seat 4 can be easily adjusted, thereby adjusting the height of the pipe port inside the concave seat 4. The pipe port is adjusted to a height suitable for manual installation, facilitating manual connection and installation of the pipe port.
