[0002] Concrete pipes are pipes made of concrete or reinforced concrete, mainly used to transport fluids such as water, oil, and gas. Concrete pipes are divided into four categories: plain concrete pipes, ordinary reinforced concrete pipes, self-stressed reinforced concrete pipes, and prestressed concrete pipes.

[0003] At present, the existing concrete drainage pipe (such as patent number: CN217634343U) discloses a reinforced concrete drainage pipe, in which a connecting base is provided at the bottom of the drainage pipe body, and connecting hanging plates and connecting rods are provided at both ends of the connecting base. The connecting rod can be hung with the connecting base of the adjacent drainage pipe body. After the two adjacent connecting bases are hung, it is convenient to align the drainage pipe body, and it can play a good limiting role on the drainage pipe body, making it not easy to roll and break. It is easy to operate and can greatly improve the installation efficiency of the drainage pipe.

[0004] However, during the implementation of the above technical solution, it was found that at least the following technical problems exist: sewage flows inside the pipe, and the sewage usually contains a lot of impurities. When the flow rate of sewage inside the pipe is low, the impurities will naturally settle and accumulate inside the pipe, causing blockage of the pipe. Utility Model Content

[0026] The embodiment of the present application provides a corrosion-resistant concrete drainage pipe, which effectively solves the problem of sewage flowing inside the pipe. Sewage usually contains a large amount of impurities. When the flow rate of sewage inside the pipe is low, the impurities will naturally settle and accumulate inside the pipe, causing blockage of the pipe. A thrust is applied to the positioning block, forcing the positioning block to slide toward the inside of the second clamping plate. The positioning block squeezes the top end of the telescopic rod, and the spring block inside the telescopic rod gradually expands and contracts, increasing the elastic potential energy of the telescopic rod itself. After the first clamping plate and the second clamping plate rotate and fit together, under the action of the telescopic rod, the telescopic rod pushes the positioning block to slide out of the inside of the second clamping plate, so that the top end of the positioning block fits into the fixing port at the side end of the first clamping plate, and the filter plate is fixed to the two side ends of the drain pipe body, thereby preventing impurities from accumulating and clogging the inside of the drain pipe body, thereby increasing the use function of the drain pipe body. Example

[0027] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the technical solution in the embodiment of the present application effectively solves the technical problem that sewage flows inside the pipe. Sewage usually contains a lot of impurities. When the flow rate of sewage inside the pipe is low, the impurities will naturally settle and accumulate inside the pipe, causing the pipe to be blocked. The overall idea is as follows:

[0028] In response to the problems existing in the prior art, the utility model provides a corrosion-resistant concrete drain pipe, which includes a drain pipe body 1, wherein two side ends of the drain pipe body 1 are fixedly installed with fixing rings 11, and two second clamping plates 14 are fixedly installed on the side ends of each fixing ring 11. A filter plate 13 is movably installed on the side ends of each fixing ring 11 located inside the second clamping plates 14, and two first clamping plates 12 are fixedly installed on the surface of the filter plate 13. The side ends of the first clamping plates 12 are provided with fixing openings. At the same time, the first clamping plates 12 and the second clamping plates 14 are each a group of two, and an inner liner coating 18 is fixedly installed on the inner side of the drain pipe body 1 symmetrically. A fixing layer 16 is fixedly installed on the surface of the inner liner coating 18, and the filter plate 13 is fixed to the two side ends of the drain pipe body 1 to prevent impurities from accumulating and clogging the interior of the drain pipe body 1, thereby increasing the use function of the drain pipe body 1.

[0029] Two reinforcing strips 17 are fixedly installed inside the fixed layer 16. The multiple reinforcing strips 17 are installed symmetrically with each other, and the reinforcing strips 17 pass through the inside of the fixed layer 16. A fiber layer 15 is fixedly installed on the outside of the fixed layer 16. The fiber layer 15 is wrapped on the outside of the fixed layer 16 by spraying. A positioning block 21 is slidably installed on the inner side of each second clamping plate 14. A telescopic rod 19 is fixedly installed on the side end of each positioning block 21, and a spring block is fixedly installed inside the telescopic rod 19.

[0030] Working principle:

[0031] The first step is to align the side end of the filter plate 13 with the inner side of the fixing ring 11 through the filter plate 13, and make the side end of the filter plate 13 fit with the fixing ring 11 by pushing the filter plate 13. At the same time, the filter plate 13 drives the first clamping plate 12 to move toward the side end of the fixing ring 11, and then rotate the filter plate 13 to drive the first clamping plate 12 to rotate on the side end of the fixing ring 11, so that the first clamping plate 12 and the second clamping plate 14 fit each other. At the same time, the first clamping plate 12 slides on the side end of the second clamping plate 14, and the filter plate 13 squeezes the top of the positioning block 21, applies thrust to the positioning block 21, and forces The positioning block 21 slides toward the inside of the second clamping plate 14, and the positioning block 21 squeezes the top of the telescopic rod 19. The spring block inside the telescopic rod 19 gradually expands and contracts, increasing the elastic potential energy of the telescopic rod 19 itself. After the first clamping plate 12 and the second clamping plate 14 rotate and fit together, under the action of the telescopic rod 19, the telescopic rod 19 pushes the positioning block 21 to slide out of the inside of the second clamping plate 14, so that the top of the positioning block 21 fits into the fixing port at the side end of the first clamping plate 12, and fixes the filter plate 13 to the two side ends of the drain pipe body 1, preventing impurities from accumulating and clogging the inside of the drain pipe body 1, thereby increasing the use function of the drain pipe body 1.

[0032] In the second step, an inner liner coating 18 is sprayed on the inner side of the drainage pipe body 1. The inner liner coating 18 is a composite polyester material, which covers the inner wall of the drainage pipe body 1 by spraying to increase the sealing of the inner side of the drainage pipe body 1. At the same time, a reinforcement strip 17 is installed on the outer side of the inner liner coating 18. The reinforcement strip 17 is fixed inside the fixed layer 16 by casting to increase the strength of the drainage pipe body 1 itself. At the same time, a fiber layer 15 is wrapped on one side of the outermost layer of the drainage pipe body 1 by winding. The fiber layer 15 is a composite material with high flexibility. It can play a protective partition role on the outer side of the drainage pipe body 1 and increase the corrosion resistance of the drainage pipe body 1 itself.

[0033] Finally, it should be noted that the above embodiments are merely examples for the purpose of illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all possible embodiments. However, any obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
