Description

Technical Field

[0001] This utility model relates to the field of drainage pipe technology, and in particular to a drainage pipe for long-distance towing construction. Background Technology

[0002] Long-distance drag-and-drop construction technology for drainage pipes is mainly used in municipal drainage pipe network projects. It is particularly suitable for pipe laying in complex environments. This technology has gradually gained widespread attention and application in municipal engineering in my country, mainly because it has less impact on roads, controllable quality, high construction efficiency, and can effectively reduce the impact on surface structures, traffic and pedestrians.

[0003] Existing drainage pipes are susceptible to mechanical damage, such as scratches and bumps, during long-distance towing construction. This damage not only affects the appearance of the pipes but also becomes the starting point for corrosion, further aggravating the damage. In addition, clamp connections need to ensure the straightness and coaxiality of both ends of the pipe; otherwise, the sealing performance of the joint will be affected, leading to water leakage at the connection. Therefore, a drainage pipe for long-distance towing construction is proposed to solve the above-mentioned problems. Utility Model Content

[0004] To address the technical issues that existing drainage pipes are susceptible to mechanical damage during long-distance towing construction, which can become the starting point for corrosion and further exacerbate pipe damage, and that clamp connections require ensuring the straightness and coaxiality of both ends of the pipe to avoid affecting the sealing performance of the joints, this application provides a drainage pipe for long-distance towing construction.

[0005] This utility model proposes a drainage pipe for long-distance towing construction, which includes a drainage pipe body, the drainage pipe body including an inner layer, a structural layer, a protective layer, a connecting pipe and a fixing pipe.

[0006] The outer surface of the drain pipe body is provided with a connecting mechanism, which includes a sleeve. The rotation of the sleeve fixes the connecting pipe and the fixing pipe.

[0007] Preferably, the inner layer is coated on the inner wall of the structural layer, and the material of the inner layer is an epoxy resin coating.

[0008] The above technical solution uses an epoxy resin coating as the inner layer, which has excellent corrosion resistance and can effectively prevent the chemical substances in sewage from corroding the inner wall of the drainage pipe body. At the same time, it improves the smoothness of the inside of the drainage pipe body, reduces fluid resistance, and thus improves drainage efficiency.

[0009] Preferably, the protective layer is applied to the outer surface of the structural layer, the protective layer is made of polyurethane coating, and the structural layer is made of high-density polyethylene.

[0010] Through the above technical solution, the protective layer is a polyurethane coating, which has good wear resistance and UV resistance, and can protect the drainage pipe body from external environmental factors such as soil and ultraviolet rays. The structural layer is the body of the drainage pipe, and the main material is high-density polyethylene, which has high strength, wear resistance, impact resistance and chemical corrosion resistance, and can withstand various environmental stresses to ensure the long-term stable operation of the drainage pipe body.

[0011] Preferably, the connecting pipe is fixedly installed at one end of the drain pipe body, and the fixing pipe is fixedly installed at the other end of the drain pipe body, with the outer surface of the fixing pipe slidably inserted into the inner wall of the groove of the connecting pipe.

[0012] The above technical solution involves fixing the drain pipe body with connecting pipes and fixing pipes respectively, and fixing it by sliding insertion of the fixing pipe and connecting pipe, which facilitates the connection and disassembly of multiple drain pipe bodies, and has strong flexibility and adaptability.

[0013] Preferably, the connecting mechanism further includes a sealing ring, which is fixedly installed on the outer surface of the fixing tube, and the inner wall of the sleeve is threadedly connected to the outer surface of the connecting tube and the outer surface of the fixing tube, respectively.

[0014] The above technical solution involves fixing the sealing ring to the fixed pipe, and then sliding the fixed pipe and connecting pipe together. The outer surface of the sealing ring contacts the outer surface of the connecting pipe to form a seal, preventing water leakage. The connecting pipe and the fixed pipe are further fixed by threaded connection of the sleeve to the connecting pipe and the fixed pipe, and the sealing ring is compressed to enhance the sealing effect.

[0015] Preferably, the inner wall of the groove of the fixing tube is slidably inserted with a ball rod arranged in a ring array, one end of the ball rod is fixedly installed with a spring, and one end of the spring is fixedly installed with one end of the other ball rod.

[0016] The above technical solution involves sliding the ball stick into the fixed tube, which fixes the ball stick without affecting its movement. The two ball sticks are symmetrically arranged and then arranged in a circular array. Springs are fixedly installed on the two symmetrically arranged ball sticks respectively. After the ball sticks are squeezed and moved, they are reset and thus locked in the limiting groove.

[0017] Preferably, the inner wall of the connecting pipe is provided with limiting grooves arranged in a ring array, and the inner wall of the limiting grooves is slidably connected to the outer surface of the cue stick.

[0018] The above technical solution involves creating a limiting groove on the inner wall of the connecting pipe. Two limiting grooves are symmetrically distributed and arranged in a ring array on the inner wall of the connecting pipe. The limiting groove is slidably connected to the cue stick through the limiting groove. The limiting groove has a triangular cross-section, which can provide precise guidance and ensure the correct reset and engagement of the cue stick.

[0019] The beneficial effects of this utility model are as follows:

[0020] 1. By setting up an inner layer, structural layer, protective layer, connecting pipe, and fixing pipe, the inner layer is an epoxy resin coating, which has excellent corrosion resistance. The protective layer is a polyurethane coating, which has good wear resistance and UV resistance. The structural layer is the body of the drainage pipe, mainly made of high-density polyethylene, which has high strength, wear resistance, impact resistance, and chemical corrosion resistance. The connecting pipe and fixing pipe are fixedly installed to the drainage pipe body and secured. The fixing pipe and connecting pipe are slidably inserted, which facilitates the connection and disassembly of multiple drainage pipe bodies. It has strong flexibility and adaptability, and solves the technical problem that existing drainage pipes are easily damaged by mechanical damage such as scratches and bumps during long-distance dragging construction. These damages not only affect the appearance of the pipe, but also become the starting point of corrosion, further aggravating the damage to the pipe.

[0021] 2. By setting up a connection mechanism, the connecting pipe and the fixed pipe are fixed. After the fixed pipe and the connecting pipe are slidably inserted, the outer surface of the sealing ring contacts the outer surface of the connecting pipe to form a seal and prevent water leakage. The connecting pipe and the fixed pipe are further fixed by threaded connection of the sleeve to the connecting pipe and the fixed pipe respectively, and the sealing ring is compressed to enhance the sealing effect. This solves the technical problem that when connecting drainage pipes, the clamp connection needs to ensure the straightness and coaxiality of both ends of the pipe, otherwise it will affect the sealing performance of the joint and cause water leakage at the connection.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0032] Reference Figures 1-8 A drainage pipe for long-distance towing construction includes a drainage pipe body 1, which includes an inner layer 2, a structural layer 21, a protective layer 3, a connecting pipe 4, and a fixing pipe 41.

[0033] To improve drainage efficiency, inner layer 2 is coated on the inner wall of the structural layer 21. The material of inner layer 2 is epoxy resin coating. Inner layer 2 is epoxy resin coating, which has excellent corrosion resistance and can effectively prevent chemical substances in sewage from corroding the inner wall of the drain pipe body 1. At the same time, it improves the smoothness of the inside of the drain pipe body 1, reduces fluid resistance, and thus improves drainage efficiency.

[0034] To ensure the long-term stable operation of the drainage pipe body 1, a protective layer 3 is applied to the outer surface of the structural layer 21. The protective layer 3 is made of polyurethane coating, and the structural layer 21 is made of high-density polyethylene. The protective layer 3, being a polyurethane coating, has good wear resistance and UV resistance, protecting the drainage pipe body 1 from external environmental factors such as soil and ultraviolet radiation. The structural layer 21 is the body of the drainage pipe, mainly made of high-density polyethylene, which has high strength, wear resistance, impact resistance, and chemical corrosion resistance, and can withstand various environmental stresses, ensuring the long-term stable operation of the drainage pipe body 1.

[0035] To facilitate the connection and disassembly of multiple drain pipe bodies 1, a connecting pipe 4 is fixedly installed at one end of the drain pipe body 1, and a fixing pipe 41 is fixedly installed at the other end of the drain pipe body 1. The outer surface of the fixing pipe 41 is slidably inserted into the inner wall of the groove of the connecting pipe 4. The connecting pipe 4 and the fixing pipe 41 are respectively fixedly installed to the drain pipe body 1. The fixing is achieved by the sliding insertion of the fixing pipe 41 into the connecting pipe 4, which facilitates the connection and disassembly of multiple drain pipe bodies 1 and has strong flexibility and adaptability.

[0036] By setting up an inner layer 2, a structural layer 21, a protective layer 3, a connecting pipe 4, and a fixing pipe 41, the inner layer 2 is an epoxy resin coating, which has excellent corrosion resistance. The protective layer 3 is a polyurethane coating, which has good wear resistance and UV resistance. The structural layer 21 is the body of the drainage pipe, mainly made of high-density polyethylene, which has high strength, wear resistance, impact resistance, and chemical corrosion resistance. The connecting pipe 4 and the fixing pipe 41 are fixedly installed to the drainage pipe body 1, and the fixing pipe 41 is slidably inserted into the connecting pipe 4, which facilitates the connection and disassembly of multiple drainage pipe bodies 1. It has strong flexibility and adaptability, and solves the technical problem that existing drainage pipes are easily damaged by mechanical damage, such as scratches and bumps, during long-distance dragging construction. These damages not only affect the appearance of the pipe, but also become the starting point of corrosion, further aggravating the damage to the pipe.

[0037] In order to fix the connecting pipe 4 and the fixing pipe 41, a connecting mechanism is provided on the outer surface of the drain pipe body 1. The connecting mechanism includes a sleeve 42, and the rotation of the sleeve 42 fixes the connecting pipe 4 and the fixing pipe 41.

[0038] To enhance the sealing effect, the connecting mechanism also includes a sealing ring 5, which is fixedly installed on the outer surface of the fixed pipe 41. The inner wall of the sleeve 42 is threadedly connected to the outer surface of the connecting pipe 4 and the outer surface of the fixed pipe 41, respectively. The sealing ring 5 is fixedly installed to the fixed pipe 41, and after the fixed pipe 41 and the connecting pipe 4 are slidably inserted, the outer surface of the sealing ring 5 contacts the outer surface of the connecting pipe 4, forming a seal to prevent water leakage. The sleeve 42 is threadedly connected to the connecting pipe 4 and the fixed pipe 41, respectively, to further fix the connecting pipe 4 and the fixed pipe 41 and to compress the sealing ring 5, thereby enhancing the sealing effect.

[0039] To allow the cue stick 6 to engage in the limiting groove 7, cue sticks 6 arranged in a circular array are slidably inserted into the inner wall of the groove of the fixing tube 41. A spring 61 is fixedly installed at one end of one cue stick 6, and one end of the spring 61 is fixedly installed at one end of another cue stick 6. The cue stick 6 is slidably inserted into the fixing tube 41, which fixes it without affecting its movement. The two cue sticks 6 are symmetrically arranged and arranged in a circular array. The spring 61 is fixedly installed on each of the two symmetrically arranged cue sticks 6. After the cue stick 6 is squeezed and moved, it is reset, thus engaging in the limiting groove 7.

[0040] To ensure the correct reset and engagement of the cue stick 6, the inner wall of the connecting tube 4 is provided with a ring-shaped array of limiting grooves 7. The inner wall of the limiting grooves 7 is slidably connected to the outer surface of the cue stick 6. The limiting grooves 7 are symmetrically distributed and arranged in a ring on the inner wall of the connecting tube 4. The limiting grooves 7 are slidably connected to the cue stick 6. The cross-section of the limiting grooves 7 is triangular, which can provide precise guidance to ensure the correct reset and engagement of the cue stick 6.

[0041] By setting a connecting mechanism, the connecting pipe 4 and the fixed pipe 41 are fixed. After the fixed pipe 41 is slidably inserted into the connecting pipe 4, the outer surface of the sealing ring 5 contacts the outer surface of the connecting pipe 4 to form a seal and prevent water leakage. The sleeve 42 is threadedly connected to the connecting pipe 4 and the fixed pipe 41 respectively to further fix the connecting pipe 4 and the fixed pipe 41 and compress the sealing ring 5 to enhance the sealing effect. This solves the technical problem that when connecting drainage pipes, the clamp connection needs to ensure the straightness and coaxiality of both ends of the pipe, otherwise it will affect the sealing performance of the joint and cause water leakage at the connection.

[0042] Working principle: When it is necessary to connect the drain pipe bodies 1 to each other, the operator inserts the fixing pipe 41 on the connecting pipe body 4 into the connecting pipe 4 until the sealing ring 5 on the fixing pipe 41 contacts the outer surface of the connecting pipe 4. When the ball rod 6 slidably inserted on the fixing pipe 41 moves to the limiting groove 7 opened on the connecting pipe 4, under the action of the spring 61, the ball rod 6 returns to its original position and engages with the limiting groove 7. Then, the sleeve 42 is rotated to make it threadedly connected to the connecting pipe 4 and the fixing pipe 41, further fixing the connecting pipe 4 and the fixing pipe 41 and compressing the sealing ring 5 to enhance the sealing effect. The epoxy resin coating of the inner layer 2 of the drain pipe body 1 can effectively resist the erosion of chemicals in sewage and protect the inner wall of the drain pipe body 1 from corrosion. The polyurethane coating of the protective layer 3 can resist the damage of ultraviolet rays and environmental factors and extend the service life of the drain pipe body 1. Its structural layer 21 is made of high-density polyethylene, which provides high strength, wear resistance, impact resistance and chemical corrosion resistance, ensuring the long-term stable operation of the drain pipe body 1.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
