Description

Technical Field

[0001] This utility model belongs to the field of drainage pipe technology, specifically relating to an urban combined sewer drainage pipe. Background Technology

[0002] Combined sewer systems, as an important component of municipal infrastructure, centrally transport rainwater and domestic sewage through a single pipeline. This has significant advantages in saving underground space and reducing initial construction investment. The mixed sewage is transported through this pipeline to a sewage treatment plant for treatment to meet standards before being discharged, or, under certain conditions, directly into natural water bodies, playing a crucial role in the urban drainage system. However, in areas with complex geological conditions or dense infrastructure, such as soft soil foundations and old urban areas, uneven settlement of pipeline foundations is prone to occur due to factors such as uneven foundation bearing capacity and ground settlement. During this process, the joints of adjacent pipelines are prone to "axial tension" or "radial displacement": when the settlement difference is distributed along the pipeline axis, a tension phenomenon with increased axial spacing will occur at the joint; when the settlement direction is perpendicular to the pipeline axis, it will cause radial misalignment. The above displacement will cause the rubber ring of the sealing component at the joint to be unbalanced in force, resulting in sewage leakage. Leakage not only causes water waste and environmental pollution, but also exacerbates the settlement due to sewage erosion of the foundation, forming a vicious cycle and significantly increasing pipeline maintenance costs.

[0013] 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 protection scope of the present utility model.

[0014] Example 1 Please see Figures 1-4This is the first embodiment of the present invention, which provides a combined sewer system for urban stormwater and sewage, including a first pipe 1 and a second pipe 2 connected together, clarifying the basic components of the pipe. It also includes a reinforcement device, comprising a first reinforcement seat 6 and a second reinforcement seat 7 disposed on the outside of the interface between the first pipe 1 and the second pipe 2. The first and second reinforcement seats 6 and 7 directly act on the outside of the pipe interface, providing external wrapping reinforcement to the interface, providing a stable support foundation for subsequent reinforcement operations, and enhancing the overall constraint capability of the interface. A first rubber plate 62, disposed on the first reinforcement seat 6 and tightly fitted to the first pipe 1 and the second pipe 2, and a second rubber plate 72, disposed on the second reinforcement seat 7 and tightly fitted to the first pipe 1 and the second pipe 2, are also included. The tight fit of the first rubber plate 62 and the second rubber plate 72 with the pipes utilizes the elastic properties of rubber to fill the small gaps between the reinforcement seat and the pipe, enhancing the sealing between the reinforcement device and the pipe, and reducing the possibility of sewage leakage from the outside of the interface. Furthermore, the rubber material has certain... The buffering effect reduces the rigid compression of the pipe outer wall by the reinforcement seat, protecting the pipe outer wall from damage. The first extension ear 61 is set on the outer side of the first reinforcement seat 6, and the second extension ear 71 is set on the outer side of the second reinforcement seat 7 and is detachably connected to the first extension ear 61. The setting of the first extension ear 61 and the second extension ear 71 provides a convenient structure for the detachment and connection of the first reinforcement seat 6 and the second reinforcement seat 7. Through the connection operation of the two, the installation and disassembly of the reinforcement seat can be quickly realized, which facilitates the installation, maintenance and replacement of the pipe. At the same time, it ensures the stability of the connection between the reinforcement seats and further enhances the reinforcement effect on the pipe interface. The positioning block 73 is set at the bottom of the second reinforcement seat 7, and the positioning hole 63 is opened inside the first reinforcement seat 6 for the positioning block 73 to be inserted. When the positioning block 73 is inserted into the positioning hole 63, it can play a precise positioning role when the first reinforcement seat 6 and the second reinforcement seat 7 are spliced, ensuring that the two are accurately positioned during installation, avoiding misalignment, and ensuring that the reinforcement seat can evenly apply the constraint force to the pipe interface, improving the accuracy and efficiency of the reinforcement device installation.

[0015] In this embodiment, preferably, a guide ring 630 is installed on the inner wall of the positioning hole 63, and the guide ring 630 is in close contact with the positioning block 73. The installation of the guide ring 630 serves two purposes: firstly, it guides the insertion of the positioning block 73 into the positioning hole 63, making the insertion process smoother and reducing the installation difficulty; secondly, the close contact between the guide ring 630 and the positioning block 73 reduces wear between the positioning block 73 and the inner wall of the positioning hole 63, while enhancing the tightness of the fit between the two and improving the stability of the positioning.

[0016] In this embodiment, preferably, the second extension ear 71 and the second reinforcing seat 7 are an integral structure, and the first extension ear 61 and the first reinforcing seat 6 are an integral structure. The integral structure can enhance the connection strength between the extension ear and the reinforcing seat, avoid the situation of breakage or loosening between the extension ear and the reinforcing seat during use, improve the overall structural stability and load-bearing capacity of the reinforcing device, and extend the service life of the device.

[0017] In this embodiment, preferably, a fixed cylinder 3 is provided at one end of the second pipe 2, and a stabilizing cylinder 4 is provided on the outside of the fixed cylinder 3. The height of the stabilizing cylinder 4 is higher than that of the fixed cylinder 3. The stabilizing cylinder 4 is sleeved on the outside of the fixed cylinder 3 and is even higher, which can further enhance the support and stabilization effect on the end of the second pipe 2, improve the deformation resistance of the pipe end, and reduce the impact on the interface caused by the shaking of the pipe end. By using the cooperation of the fixed cylinder 3 and the stabilizing cylinder 4, the treated water can be discharged into the river.

[0018] In this embodiment, preferably, the outer wall of the stabilizing cylinder 4 is provided with symmetrically distributed fastening discs 5, and the side surface of the fastening discs 5 is provided with a waterproof electric push rod 51. The symmetrically distributed fastening discs 5 provide a stable installation base for the waterproof electric push rod 51. The setting of the waterproof electric push rod 51 provides a power source for subsequent tightening operations on the pipeline, and the waterproof characteristics ensure that the electric push rod can work normally in a humid environment, thus improving the applicability of the device.

[0019] Example 2 Please see Figures 1-4 This is the second embodiment of the present invention, which is based on the previous embodiment, but differs in that: It also includes symmetrically opened connecting grooves 41 on the inner side of the stabilizing cylinder 4. The output end of the waterproof electric push rod 51 passes through the fastening plate 5 and is connected to the arc plate 8. The connecting groove 41 provides a channel for the movement of the arc plate 8. The waterproof electric push rod 51 pushes the arc plate 8 to move through the connecting groove 41. A protective net 81 is installed on the inner side of the arc plate 8, and the arc plate 8 can be inserted into the interior of the connecting groove 41. When the river rises during rainy days, the river water will enter the pipe through the drain outlet of the drain pipe. The water flow will carry garbage in the river water, such as plastic bags and branches, into the second pipe 2. The protective nets 81 are connected together to increase the garbage blockage caused by the backflow of river water. The arc plate 8 can be inserted into the interior of the connecting groove 41, which makes it easy to store the arc plate 8 when not in use, reduce space occupation, and ensure smooth drainage.

[0020] The working principle and usage process of this utility model are as follows: the first pipe 1 and the second pipe 2 are spliced ​​together so that the interfaces of the two are accurately connected, which prepares for the subsequent installation of the reinforcement device. Align the positioning block 73 at the bottom of the second reinforcing seat 7 with the positioning hole 63 inside the first reinforcing seat 6. Under the guidance of the guide ring 630, insert the positioning block 73 into the positioning hole 63 to achieve precise positioning of the first reinforcing seat 6 and the second reinforcing seat 7. Make the first rubber plate 62 on the first reinforcing seat 6 and the second rubber plate 72 on the second reinforcing seat 7 fit tightly against the first pipe 1 and the second pipe 2, respectively. By connecting the first extension ear 61 and the second extension ear 71, the first reinforcing seat 6 and the second reinforcing seat 7 are fixed together to complete the wrap-around reinforcement of the pipe interface. A fixing cylinder 3 is installed at one end of the second pipe 2, and a stabilizing cylinder 4 is set on the outside of the fixing cylinder 3. The cooperation of the fixing cylinder 3 and the stabilizing cylinder 4 enhances the support and stabilization effect on the end of the second pipe 2, and at the same time enables the treated water to be discharged into the river through this structure. A symmetrically distributed fastening plate 5 is installed on the outer wall of the stabilizing cylinder 4, and a waterproof electric push rod 51 is installed on the side surface of the fastening plate 5. During routine drainage, the curved plate 8 is inserted into the connecting groove 41 for storage, reducing space occupation and ensuring smooth drainage; When the river rises during rainy days, the river water may backflow into the pipe through the drain outlet. At this time, the waterproof electric push rod 51 is controlled to push the arc plate 8 to move, so that the protective net 81 on the inner side of the arc plate 8 is connected together, preventing plastic bags, branches and other garbage in the river water from entering the second pipe 2, thus reducing the possibility of garbage blockage.

[0021] Although embodiments of the present invention have been shown and described in detail above, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
