Description

Technical Field

[0001] This utility model relates to the field of tongue and groove drainage pipe technology, specifically a lightweight, high-strength reinforced concrete tongue and groove drainage pipe. Background Technology

[0002] Lightweight, high-strength reinforced concrete tongue-and-groove drainage pipes are a high-quality pipe widely used in modern municipal, transportation, and water conservancy projects. By optimizing the concrete mix ratio and using high-strength steel reinforcement, the pipe body achieves extremely high load-bearing capacity while minimizing its weight. This facilitates transportation and installation and reduces the requirements for the foundation. The "tongue and groove" joint is a common pipe connection type, with one end being a "protruding" (tenon) and the other end a "recessed" (groove). During installation, the protruding end of one pipe is inserted into the recessed end of another, and a rubber sealing ring is embedded at the joint to form a sealed, flexible connection. However, relying on the initial compression of the rubber ring to provide sealing force has limited effectiveness. When excessive foundation settlement occurs, the joint may be pulled open, leading to leakage. Therefore, we propose a lightweight, high-strength reinforced concrete tongue-and-groove drainage pipe.

[0004] Therefore, the technical solution adopted by this utility model is as follows: a lightweight high-strength reinforced concrete tongue and groove drainage pipe, including a drainage pipe body, a first expansion strip, a second expansion strip, a sealing component, and a sludge removal component. The drainage pipe body includes a pipe body, a first locking block fixedly disposed on the outer side of the left part of the pipe body, and a second locking block fixedly connected to the outer side of the right part of the pipe body. The first expansion strip is inserted through the outer side of the left part of the pipe body, and the second expansion strip is inserted through the outer side of the right part of the pipe body. The sealing component includes an upper sealing plate abutting against the top of the pipe body, a lower sealing plate abutting against the bottom of the upper sealing plate and connected to the pipe body, and fasteners fixedly installed on the lower sealing plate. The sludge removal component is fixedly disposed on the top of the pipe body.

[0005] Preferably, the outside of the tube body is fixedly provided with a plurality of reinforcing ribs, and the shape of the plurality of reinforcing ribs is annular.

[0006] Preferably, the second card block and the first card block have the same structure, and both the second card block and the first card block are annular in shape.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0022] The following description, in conjunction with the accompanying drawings, describes some embodiments of this utility model that provide a lightweight, high-strength reinforced concrete tongue-and-groove drainage pipe.

[0023] Example 1:

[0024] Reference Figure 1-4 This is the first embodiment of the present utility model, which provides a lightweight, high-strength reinforced concrete tongue-and-groove drainage pipe, including a drainage pipe body 100, a first expansion strip 200, a second expansion strip 300, a sealing component 400, and a sludge removal component 500.

[0025] Specifically, the drain pipe body 100 includes a pipe body 101, a first locking block 103 fixedly disposed on the outer left side of the pipe body 101, and a second locking block 104 fixedly connected to the outer right side of the pipe body 101. The second locking block 104 and the first locking block 103 have the same structure, and both the second locking block 104 and the first locking block 103 are annular in shape. Several reinforcing ribs 102 are fixedly disposed on the outside of the pipe body 101. The several reinforcing ribs 102 are all annular in shape. In use, the second locking block 104 and the first locking block 103 can be engaged with the sealing component 400 so that two adjacent drain pipe bodies 100 can be connected through the sealing component 400. The several reinforcing ribs 102 can improve the strength of the drain pipe body 100 and extend the service life of the drain pipe body 100.

[0026] Specifically, the first expansion strip 200 is inserted on the outer side of the left side of the pipe body 101. When in use, the first expansion strip 200 can expand when it comes into contact with water, preventing sewage from leaking out through the gap between the outer side of the drain pipe body 100 and the right side of the sealing component 400.

[0027] Specifically, the second expansion strip 300 is inserted on the outside of the right side of the pipe body 101. When in use, the second expansion strip 300 can expand when it comes into contact with water, preventing sewage from leaking out through the gap between the outside of the drain pipe body 100 and the left side of the sealing component 400.

[0028] Specifically, the sealing assembly 400 includes an upper sealing plate 401 abutting against the top of the tube body 101, a lower sealing plate 402 abutting against the bottom of the upper sealing plate 401 and connected to the tube body 101, and a fastener 403 fixedly installed on the lower sealing plate 402. The inner sides of the upper sealing plate 401 and the lower sealing plate 402 are sequentially provided with a first slot 4011 and a second slot 4012 from the outside to the inside, and the first slot 4011 and the second slot 4012 have the same structure. Two slots 4012 are provided. In use, the upper sealing plate 401 and the lower sealing plate 402 can be fixed to the outside of the pipe body 101 by fasteners 403, so that two adjacent drainage pipe bodies 100 can be connected to avoid excessive foundation settlement and leakage. The first slot 4011 can be engaged with the first block 103 and the second block 104, and the second slot 4012 can be engaged with the first expansion strip 200 and the second expansion strip 300 to install the sealing assembly 400.

[0029] Specifically, the dredging component 500 is fixedly installed on the top of the pipe body 101. The dredging component 500 includes a dredging pipe 501 fixedly installed on the top of the pipe body 101 and a top cover 502 fixed to the top of the dredging pipe 501 by fasteners 403. Several fasteners 403 are composed of bolts and nuts. In use, the top cover 502 can be removed by disassembling the fasteners 403. After disassembly, it can be connected to the high-pressure flushing vehicle by means of flange connection. After connection, the high-pressure flushing vehicle can deliver flushing water through the dredging pipe 501 to clean the sludge.

[0030] The working principle and usage process of this utility model are as follows: In use, the two drain pipe bodies 100 can be joined together. After joining, the upper sealing plate 401 and lower sealing plate 402 of the sealing assembly 400 are placed outside the drain pipe body 100. The two first slots 4011 are aligned with the first locking block 103 and the second locking block 104, and inserted. After insertion, the two second slots 4012 will be inserted and connected with the first expansion strip 200 and the second expansion strip 300. Then, the upper part can be fixed by fastener 403. After the sealing plate 401 and the lower sealing plate 402 are fixed, they can be connected and fixed to the two drain pipe bodies 100 through the sealing assembly 400. The first expansion rubber strip 200 and the second expansion rubber strip 300 will expand when they come into contact with water, which can prevent sewage leakage. When dredging is required, the fasteners 403 on the top cover 502 can be removed. After removal, the top cover 502 and the dredging pipe 501 can be separated. Then the dredging pipe 501 can be connected to the high-pressure flushing vehicle. After connection, the high-pressure flushing vehicle can deliver flushing water through the dredging pipe 501 to clean the sludge.
