[0002] During the construction of municipal pipelines, the connection structure between pipelines is particularly important, which determines the stability, safety and reliability of the pipeline system. The quality of the connection structure directly affects the operating efficiency and service life of the pipeline system. A good connection structure can effectively prevent leakage, breakage and damage, and also reduce maintenance and repair costs.

[0003] However, municipal pipelines are heavy and large in size. During the construction and layout process, the pipelines are suspended in the air by a crane. At this time, the pipelines are prone to rotation, making it difficult to align the pipelines when connecting them. Manual traction is required, which is inconvenient and poses a safety hazard.

[0004] Therefore, a new solution needs to be proposed to solve the problem of difficulty in aligning and connecting pipelines in pipeline construction and layout projects. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a stable connection structure for drainage pipes, so as to solve the problem that pipes are difficult to align and connect in pipe construction and layout projects.

DETAILED DESCRIPTION

[0018] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0019] Embodiment: The stable connection structure of the drainage pipe, such as Figure 1As shown, it includes a circular base 1 and a rectangular bottom plate 2 rotatably connected thereto. Both the base 1 and the bottom plate 2 are made of stainless steel. The stainless steel material has high strength, so that the base 1 and the bottom plate 2 can withstand greater pressure and are not easily deformed by the force. The top surface of the bottom plate 2 is slidably connected along the length direction of the pipeline with two stainless steel support members 3 for supporting the pipeline. The multiple support members 3 are of the same size and are horizontally symmetrically arranged. Two driving members 4 that drive the support members 3 to move in a direction approaching each other are rotatably connected at both ends of the width of the bottom plate 2. The driving members 4 are made of stainless steel. The stainless steel material has strong corrosion resistance and can resist the erosion of rainwater and most chemical substances, so that the pipeline connection structure can resist erosion in a long-term underground environment, thereby improving the service life and weather resistance.

[0020] like Figure 1 and Figure 2 As shown, a square groove 5 is formed on the top surface of the bottom plate 2 along the length direction of the pipeline, and a rectangular stainless steel protrusion 6 is fixedly connected to the bottom surface of the support member 3 along the length direction of the pipeline, so that the protrusion 6 can be slidably connected in the groove 5 along the length direction of the pipeline, and the height and width of the protrusion 6 are the same as the depth and width of the groove 5, thereby preventing the support member 3 from shifting during the sliding process. Two square stainless steel support plates 7 are fixedly connected at both ends of the width of the bottom plate 2, and an external thread is provided on the outer peripheral wall of the driving member 4. A circular through hole is formed through the support plate 7 along the length direction of the pipeline, and an internal thread is provided in the through hole. The driving member 4 passes through the through hole on the support plate 7 by means of a threaded connection.

[0021] like Figure 1 and Figure 2 As shown, an arc-shaped recess 9 is provided on the top surface of the support member 3. The top surface of the support member 3 is located outside the recess 9 and is detachably connected to an arc-shaped stainless steel fixing member 10. The inner circumferential wall of the recess 9 and the inner circumferential wall of the fixing member 10 are fixedly connected with three arc-shaped abutting members 11. The abutting members 11 are made of EPDM rubber. The EPDM rubber has good elasticity and wear resistance as well as strong corrosion resistance. When the pipeline is placed in the recess 9 on the support member 3 by a crane, the abutting members 11 are used to provide a buffer when placing the pipeline, thereby avoiding collision and wear of the pipeline and improving the service life of the pipeline. The fixing member 10 is used to reinforce the pipeline placed on the support member 3, and the direction of pipeline laying can be adjusted by rotating the bottom plate 2.

[0022] like Figure 1 and Figure 2As shown, one end of the driving member 4 away from the support member 3 is fixedly connected with a stainless steel circular rotating handle 8, and the end surface of the driving member 4 passing through the support plate 7 abuts against the end surface of the support member 3 close to the support plate 7. When the driving member 4 rotates in the clockwise direction, the driving member 4 moves in the direction away from the rotating handle 8 and drives the support member 3 abutting against it to move in the direction away from the rotating handle 8. The ends of the two pipes respectively fixed on the support member 3 close to each other are respectively provided with a cylindrical hollow stainless steel clamping block 12 and a cylindrical clamping groove 13. The clamping block 12 and the clamping groove 13 are formed integrally when the pipe is prefabricated. The length of the driving member 4 is greater than the maximum distance between the support member 3 and the fixing member 14.

[0023] like Figure 1 and Figure 2 As shown, when the two support members 3 move toward each other, the clamping block 12 enters the clamping groove 13 and clamps together. The two pipes can be accurately connected together without manual pulling and alignment of the pipes, which improves the efficiency of pipe construction and reduces potential safety hazards during construction. The diameter and length of the clamping block 12 are the same as the diameter and depth of the clamping groove 13, which improves the tightness of the two pipes when they are clamped together. A set of fixing members 14 made of stainless steel material is detachably connected at the clamping point of the clamping block 12 and the clamping groove 13. A layer of sealing member 15 is provided on the inner peripheral wall of the fixing member 14. The sealing member 15 is made of EPDM rubber material, which has the effect of blocking gas and liquid penetration. The fixing member 14 can reinforce the pipe connection while the sealing member 15 inside it seals the connection port to avoid leakage at the pipe connection, thereby improving the safety factor during pipe operation.

[0024] Working principle: Use a crane to place two pipes that need to be connected together on two support members 3 respectively, and then fix the pipes through a fixing member 10. The direction of pipe laying can be adjusted by rotating the base plate 2. Rotating the rotating members on both sides of the base plate 2 in a clockwise direction drives the two support members 3 to move in a direction close to each other, so that the clamping block 12 and the clamping groove 13 are clamped together. The fixing member 14 is used to reinforce the pipe connection, and the sealing member 15 inside it seals the connection port.

[0025] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
