Abstract
Description
Technical Field
[0001] This utility model belongs to the field of sewage treatment technology, and in particular relates to a backfill structure for large-diameter rainwater and sewage pipes. Background Technology
[0002] Wastewater treatment refers to the technical process of removing pollutants from water through physical, chemical and biological means to make it meet the standards for discharge or reuse. Its core objective is to reduce the harm of wastewater to natural water bodies, soil and ecosystems, while realizing the recycling of water resources. The quality of treated water is divided into different levels according to its use, such as agricultural irrigation. This technology is widely used in the treatment of urban domestic sewage, industrial wastewater and rural non-point source pollution, and is a key link in improving the water environment and ensuring water safety.
[0003] Sewage pipes are a common type of sewage treatment equipment. Sewage pipes are usually laid in pre-excavated trenches. However, the trench walls lack supporting structures, which makes the trench walls prone to deformation due to soil slippage or collapse. Workers need to clean the trenches before backfilling can be carried out, which affects the smooth progress of the project construction. To address this, we have proposed a backfilling structure for large-diameter stormwater and sewage pipes. Utility Model Content
[0004] The purpose of this invention is to provide a backfill structure for large-diameter stormwater and sewage pipes. By setting up a side reinforcement component, specifically by rotating a double-ended screw rod counterclockwise, the screw rod, through a threaded connection between its outer surface and the center of two square-round protrusions on the right side, moves the two protrusions in a direction away from each other. As the protrusions move away from each other, the bottom reinforcement side plate moves through a fixed connection. This allows the two reinforcement side plates to move by rotating the double-ended screw rod, ensuring that the side of the two reinforcement side plates that is away from each other contacts and supports the trench wall. This prevents trench deformation due to soil slippage or collapse, ensuring smooth construction. It solves the problem that existing sewage pipes are usually laid in pre-excavated trenches, but these trench walls lack support structures, making them prone to deformation due to soil slippage or collapse. This necessitates cleaning before backfilling, hindering the smooth progress of construction.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model relates to a backfilling structure for large-diameter stormwater and sewage pipes, comprising a side reinforcement component and an auxiliary component. The auxiliary component includes a component tank, and the side reinforcement component includes a component outer box. A bidirectional screw rod is disposed at the center of the right side inside the component outer box. A pipe body is disposed at the bottom of the bidirectional screw rod. Reinforcing side plates are disposed on both the front and back of the pipe body. The two reinforcing side plates are mirror images of the pipe body. Square and round protrusions are fixedly connected to the left and right sides of the top of the two reinforcing side plates. An internal thread is disposed at the center of the two square and round protrusions on the right side. The two reinforcing side plates are threaded to the outer surface of the bidirectional screw rod through the internal thread of the square and round protrusions. By setting the internal thread of the square and round protrusions, the square and round protrusions can be threaded to the outer surface of the bidirectional screw rod through the internal thread, allowing the square and round protrusions to move with the rotation of the bidirectional screw rod, thereby driving the bottom fixedly connected reinforcing side plates to move and adjusting the distance between the two reinforcing side plates.
[0007] Furthermore, a discharge pump is fixedly connected to the bottom of the component tank, and a tank cover is fixedly connected to the top of the component tank. A spur gear 1 is provided at the center of the top of the tank cover. Four spur gears 2 are meshed on the outer surface of the spur gear 1. The four spur gears 2 are arranged in a circumferential array around the spur gear 1. The bottom of each of the four spur gears 2 penetrates the tank cover and extends downward. The penetrated part of the tank cover is rotatably connected to the spur gear 2. A drive shaft is fixedly connected to the bottom of each of the four spur gears 2. A connector is fixedly connected to the outer surface of the drive shaft. Several stirring blades are arranged in a circumferential array on the outer surface of the connector. The side of the stirring blades near the drive shaft is fixedly connected to the outer surface of the connector. By setting the threaded connection between the outer surfaces of the four spur gears 2 and the outer surface of the spur gear 1, the spur gear 1 can drive the four spur gears 2 in the circumferential array on its outer surface to rotate, thereby controlling the rotation of the four synchronous pulleys.
[0008] Furthermore, a component top plate is provided on the top of the component outer box. Hydraulic push rods are fixedly connected to the left and right sides of the bottom of the component top plate. The output ends of the two hydraulic push rods are fixedly connected to the left and right sides of the top outer surface of the component outer box. Two threaded slots are provided on the left and right sides of the two reinforcing side plates. The two threaded slots are arranged in a longitudinal horizontal array with the side edge of the reinforcing side plate as the center. Three fixing teeth are fixedly connected to the bottom of the two reinforcing side plates. A support component is provided at the bottom of the component top plate. The support component includes two inverted Y-shaped support plates. The two inverted Y-shaped support plates are fixedly connected to the center of the back and front of the bottom of the component top plate, respectively. Two rollers are rotatably connected to the bottom of the inverted Y-shaped support plates. By providing threaded slots, the operator can fix the template to the left and right sides of the two reinforcing side plates through the threaded slots, and make the two reinforcing side plates and the template form a whole.
[0009] Furthermore, a cylindrical slide bar is provided on the left side of the bidirectional lead screw. This cylindrical slide bar passes through two square-round protrusions on the left side and extends forward and backward. Both the front and back sides of the cylindrical slide bar are fixedly connected to the inner surface of the component outer box. The outer surface of the cylindrical slide bar is slidably connected to the inner surface of the point where the square-round protrusions are penetrated. Two synchronous pulleys are provided on the back side of the bidirectional lead screw. The center of the front side of the left synchronous pulley is fixedly connected to the center of the back side of the bidirectional lead screw. The back sides of both synchronous pulleys are rotatably connected to the inner surface of the component outer box. The outer surfaces of the two synchronous pulleys... A synchronous belt is provided, and the two synchronous pulleys are connected to each other through the synchronous belt. A motor is provided on the front of the synchronous pulley on the right side. The bottom of the motor is fixedly connected to the inner surface of the outer box of the component. The output end of the back of the motor is fixedly connected to the front of the synchronous pulley on the right side through a coupling. By setting the transmission connection between the two synchronous pulleys and the synchronous belt, the synchronous belt can drive the two synchronous pulleys to rotate synchronously. The motor can drive the synchronous pulley on the right side to rotate through its output end, and the synchronous belt can drive the synchronous pulley on the left side to rotate the bidirectional lead screw.
[0010] Furthermore, a gear housing is fitted onto the outer surface of the second spur gear. The bottom of the gear housing is fixedly connected to the top cover of the tank. The top center of the first spur gear extends upward through the top of the first spur gear and is rotatably connected. A second motor is fixedly connected to the top center of the gear housing. The output end of the second motor is fixedly connected to the top of the first spur gear via a coupling. A feed funnel is provided on the left side of the gear housing. The feed funnel extends downward through the top cover of the tank and is fixedly connected to the top cover of the tank at the point through which it is passed. By providing the gear housing, the first spur gear and the four second spur gears can be protected, and the second motor at the top can be supported. By providing the second motor, the rotation of the first spur gear can be controlled, and the rotation of the four second spur gears can be controlled through meshing connection.
[0011] This utility model has the following beneficial effects:
[0012] 1. This utility model, by setting up a side reinforcement component, specifically by rotating a double-sided screw rod counterclockwise, causes the double-sided screw rod to move the two square and round protrusions in a direction away from each other through the threaded connection between the outer surface of the double-sided screw rod and the center of the two square and round protrusions on the right side. When the square and round protrusions move away from each other, they will move the bottom reinforcement side plate through the fixed connection. In this way, by rotating the double-sided screw rod, the two reinforcement side plates can be moved, so that the side of the two reinforcement side plates that is away from each other can contact the trench wall and support it, so as to avoid trench deformation caused by soil slippage or collapse and ensure that construction can proceed smoothly.
[0013] 2. This utility model incorporates an auxiliary component, specifically a rotating spur gear one. This spur gear one, through meshing, drives four spur gears two arranged in a circumferential array on its outer surface to rotate. When the spur gears two rotate, they drive the transmission shaft at the bottom to rotate, which in turn drives the stirring blades to rotate through the connecting parts. In this way, the rotation of the stirring blades stirs the material inside the component tank, mixing the material together and keeping it in a flowing state. Then, it is transported to the bottom pipe trench by the unloading pump to pour into the pipe trench, preventing the pipe from contacting corrosive media and extending the service life of the pipe.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0024] Please see Figures 1-5As shown, this utility model is a backfill structure for a large-diameter stormwater and sewage pipe, including a side reinforcement component 1 and an auxiliary component 2. The auxiliary component 2 includes a component tank body 211, and the side reinforcement component 1 includes a component outer box 13. A bidirectional screw rod 141 is provided at the center of the right side inside the component outer box 13. A pipe body 18 is provided at the bottom of the bidirectional screw rod 141. Reinforcing side plates 161 are provided on both the front and back of the pipe body 18. The two reinforcing side plates 161 are mirror images of the pipe body 18. Square and round protrusions 162 are fixedly connected to the left and right sides of the top of the two reinforcing side plates 161. The center of the two square and round protrusions 162 on the right side is provided with internal threads. The two reinforcing side plates 161 are connected through the square and round protrusions 162. The internal thread of the 2 is connected to the external thread of the double-sided screw 141. By setting the side reinforcement component 1, specifically by rotating the double-sided screw 141 counterclockwise, the double-sided screw 141 is connected to the center of the two square and round protrusions 162 on the right side through the threaded connection of the outer surface of the double-sided screw 141. This causes the two square and round protrusions 162 to move away from each other. When the square and round protrusions 162 move away from each other, the bottom reinforcement side plate 161 will move through the fixed connection. In this way, by rotating the double-sided screw 141, the two reinforcement side plates 161 can be moved, so that the side of the two reinforcement side plates 161 that is away from each other can contact the trench wall and support it, so as to avoid trench deformation due to soil slippage or collapse and ensure that the construction can proceed smoothly.

The side of plate 253 closest to the drive shaft 251 is fixedly connected to the outer surface of the connector 252. By setting the auxiliary component 2, specifically rotating the first spur gear 231, the first spur gear 231 will drive the four second spur gears 232 arranged in a circumferential array on the outer surface to rotate through meshing connection. When the second spur gears 232 rotate, they will drive the drive shaft 251 at the bottom to rotate, and drive the stirring blades 253 to rotate through the connector 252. In this way, the material inside the component tank 211 can be stirred by the rotation of the stirring blades 253, mixing the material together and keeping it in a flowing state. Then, it is transferred to the bottom pipe trench by the unloading pump 212 to pour into the pipe trench, preventing the pipe from contacting corrosive media and extending the service life of the pipe.

The outer surface of the cylindrical slide rod 142 is slidably connected to the inner surface of the square and round protrusions 162 through which it is passed. Two synchronous pulleys 151 are provided on the back of the bidirectional lead screw 141. The center of the front of the synchronous pulley 151 located on the left side is connected to the back of the bidirectional lead screw 141.

[0029] A specific application of this embodiment is as follows: When in use, first move the equipment to the top of the ditch, then start the motor 153, which drives the right synchronous wheel 151 to rotate counterclockwise, and through the synchronous belt 152, drives the left synchronous wheel 151 to rotate the double-acting screw 141 counterclockwise.

[0031] Finally, the material is fed into the component tank 211 from the feed funnel 222. Then, the motor 24 is started to rotate the spur gear 231 and the four spur gears 232 are also rotated through the meshing connection. When the four spur gears 232 rotate, they will drive the transmission shaft 251 fixedly connected to the bottom to rotate. When the transmission shaft 251 rotates, it drives the stirring blades 253 to rotate through the connector 252 to mix the material and keep it in a flowing state. Finally, the discharge pump 212 is started to transport the material into the interior of the reinforced side plate 161 and the template. After the material solidifies, the equipment is removed.
