Abstract
Description
Technical Field
[0001] This utility model belongs to the field of pipeline laying technology, and in particular relates to a pipeline and well body connection device. Background Technology
[0002] In municipal engineering, power and telecommunications, and other fields, the connection between pipelines and prefabricated manholes is a key technical aspect. MPP pipes, also known as MPP power cable protection pipes, are divided into open-cut and trenchless types. Trenchless MPP pipes are also called MPP jacking pipes or drag pipes. MPP pipes use modified polypropylene as the main raw material and are characterized by high temperature resistance and external pressure resistance.
[0003] Traditional methods often involve directly casting concrete to fix the pipes, requiring on-site formwork and manual adjustment of the pipe position. This presents several problems: the concrete requires a long curing period before the supports can be removed, delaying the construction schedule; concrete easily seeps into the pipe's inner wall, making subsequent cable installation difficult and leading to high rework rates; the pipe is prone to displacement due to concrete flow, affecting axis alignment; insufficient concrete vibration can cause air bubbles or cracks, leading to leaks at the joints; and dimensional deviations at the precast manhole connection points can easily cause the fixing devices to loosen, requiring additional reinforcement. Therefore, there is an urgent need for an efficient, reliable, and adaptable pipe-to-manhole connection device and construction method. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a pipe-well connection device, which is particularly suitable for the connection and construction of MPP power pipes and power wells.
[0005] The technical solution adopted by this utility model is as follows: Firstly, a pipe-well connection device is provided for installing a pipe within a connection port of the well body, comprising:
[0006] The first side sealing plate is disposed inside the connection port of the well body;
[0007] The second side sealing plate is disposed on the outside of the connection port of the well body;
[0008] A first bearing sleeve is disposed on the first side sealing plate to accommodate the pipe;
[0009] The second bearing sleeve is disposed on the second side sealing plate and is used to accommodate the pipe;
[0010] A vibration box, one end of which is positioned on the first side sealing plate;
[0011] Vibration-absorbing strips are disposed on the inner surface of the vibration box;
[0012] A vibration leveling strip is provided on the outer surface of the vibration box.
[0013] Furthermore, it also includes a flipping component, which is disposed at the upper end of the second side sealing plate.
[0014] Furthermore, it also includes a first additional slide and a second additional slide, the first additional slide being disposed at the edge of the first side sealing plate and the second additional slide being disposed at the edge of the second side sealing plate.
[0015] Furthermore, it also includes a sealing ring, which is provided at the connection between the first bearing sleeve and the first side sealing plate, and at the connection between the second bearing sleeve and the second side sealing plate.
[0016] Furthermore, the flipping component includes:
[0017] A rotating plate, the two ends of which are disposed on the upper end of the second side sealing plate;
[0018] A bonding plate is provided at the end of the rotating plate;
[0019] A limiting block is provided on the bonding plate. The limiting block is engaged with the outer wall of the second side sealing plate to limit the rotation angle of the rotating plate.
[0020] Furthermore, it also includes an outer sealing gasket, which is fitted over the outside of the first side sealing plate.
[0021] The advantages and positive effects of this utility model are as follows: By adopting the above-mentioned technical solution, the use of independently installed mechanical clamping structures on both the inner and outer sides replaces the overall pouring, eliminating the need for formwork and curing during construction, significantly shortening the construction period. Through the cooperation of elastic sealing elements and rigid support components, radial sealing and seepage prevention of the pipeline are achieved, while ensuring no misalignment or displacement of the interface after concrete pouring, improving the seismic resistance and stability of the connection points. The innovative introduction of a vibration transmission mechanism can simultaneously eliminate air bubbles and voids during concrete pouring, avoiding the blind spots of traditional vibrators and ensuring a dense and uniform structure after curing. The device has strong adaptability, allowing for certain dimensional tolerances between the well body interface and the pipeline, and reducing construction difficulty through adjustable interference fits and modular assembly. Furthermore, the corresponding construction method has a high degree of standardization, reducing reliance on operator experience through step-by-step collaborative operation, significantly improving project consistency and reliability.

[0032] The present disclosure will now be described more fully with reference to the accompanying drawings, which illustrate exemplary embodiments of the present disclosure. The technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present disclosure, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present disclosure without creative effort are within the scope of protection of the present disclosure.
[0033] like Figure 1 As shown, this utility model provides a pipe-well connection device for placing a pipe inside the connection port of the well body. It includes a first side sealing plate 100 disposed inside the connection port of the well body; a second side sealing plate 200 disposed outside the connection port of the well body; a first bearing sleeve 300 penetrating the first side sealing plate 100 and fixed inside it, for accommodating the pipe; a second bearing sleeve 400 penetrating the second side sealing plate 200 and fixed inside it, for accommodating the pipe; a vibration box 500, with one opening located at the lower center of the first side sealing plate 100; a vibration strip 600 disposed on the inner surface of the vibration box 500; and a vibration leveling strip 700 disposed on the outer surface of the vibration box 500.
[0034] By using the above-mentioned device, with the first and second side sealing plates placed on the outside and outside of the well body respectively, combined with the bearing casing to restrict the position of the pipeline, and the vibration design of the vibration box, vibration strip and vibration leveling strip, the problems of pipeline displacement and sealing failure caused by traditional concrete fixing can be solved.
[0035] To address the issues of concrete needing to be poured from outside the well body, which restricts construction space and easily pollutes the environment, this embodiment provides an implementation method.
[0036] like Figure 2 As shown, it also includes a flipping component 800, which is disposed at the upper end of the second side sealing plate 200.
[0037] The above-mentioned device facilitates concrete injection and improves the efficiency and controllability of the injection process.
[0038] To address the issue that relying solely on interference fit for the side sealing plate can lead to displacement due to concrete pressure, resulting in insufficient installation stability, this embodiment provides an implementation method.
[0039] like Figure 3 As shown, it also includes a first additional drag plate 900 and a second additional drag plate 110. The first additional drag plate 900 is connected to the edge of the first side sealing plate 100, and its outer inclined surface contacts the inner wall of the well body to form an interference fit. The second additional drag plate 110 is connected to the edge of the second side sealing plate 200, and its outer inclined surface contacts the inner wall of the well body to form an interference fit.
[0040] Using the above-mentioned device, the side sealing plate is pre-fixed by forming an interference fit with the inner wall of the well body through the contact of the drag plate, which reduces the risk of side sealing plate displacement during concrete pouring.
[0041] To address the issue of concrete potentially seeping into the inner pipe along the gap between the bearing sleeve and the pipe, and to further improve sealing, this embodiment provides an implementation method.
[0042] like Figure 3 As shown, it also includes a sealing ring 120, the inner diameter of which is 2mm smaller than the outer diameter of the pipe. A sealing ring 120 is provided at the connection between the first bearing sleeve 300 and the first side sealing plate 100, and a sealing ring 120 is provided at the connection between the second bearing sleeve 400 and the second side sealing plate 200. The sealing ring 120 is embedded in the annular groove at the end of the bearing sleeve.
[0043] Using the above-mentioned device, the sealing ring is pressed tightly against the outer wall of the pipe, forming a radial seal and completely blocking the leakage path of concrete slurry.
[0044] To address the issue of concrete overflow caused by deviations in the opening and closing angles of the flipping component, this embodiment provides an implementation method for precisely controlling the position of the rotating plate.
[0045] like Figure 3As shown, the flipping component 800 includes a rotating plate 801, a bonding plate 802, and a limiting block 803. The rotating plate 801 is mounted on the upper end of the second side sealing plate 200 via a hinge and can rotate 0-90° around an axis. The bonding plate 802 is connected to the end of the rotating plate 801. The upper surface of the bonding plate 802 is arc-shaped to ensure that the rotating plate 801 can be opened after the second side sealing plate 200 is installed with the connection port. When closed, it is bonded to the outer wall of the second side sealing plate 200. The limiting block 803 is fixed on the bonding plate 802 to limit the opening and closing angle of the rotating plate 801.
[0046] By using the above-mentioned device, the opening and closing angle of the rotating plate is limited by the limiting block, which effectively prevents concrete seepage.
[0047] To address the sealing failure and aesthetic issues caused by uneven well walls, this embodiment provides an implementation method.
[0048] like Figure 4 As shown, it also includes an outer sealing gasket 130, which is fitted onto the outside of the first side sealing plate 100 and fixed to the groove of the side sealing plate by a snap fastener.
[0049] Using the above-mentioned device, the outer sealing gasket compensates for the installation gap between the inner wall of the well body and the side sealing plate, assists in forming a secondary seal, and improves waterproof performance and aesthetics.
[0050] The following description, in conjunction with a preferred embodiment, illustrates the content involved in the above embodiments.
[0051] A pipe-well connection device includes a first side sealing plate 100, a second side sealing plate 200, a first bearing sleeve 300, a second bearing sleeve 400, a vibration box 500, a vibration deflector strip 600, a vibration leveling strip 700, a first auxiliary drag plate 900, a second auxiliary drag plate 110, a sealing ring 120, a rotating plate 801, a bonding plate 802, and a limiting block 803. The first side sealing plate 100 is located inside the well body connection port and is made of steel plate or hard plastic. A first auxiliary sliding plate 900 is welded to its edge, and its inner surface is machined with an annular groove for fitting with the first bearing sleeve 300. The second side sealing plate 200 is symmetrically located outside the well body connection port relative to the first side sealing plate 100. Its material and structure are the same as the first side sealing plate 100, and a second auxiliary sliding plate 110 is welded to its edge. Its inner surface is machined with an annular groove for fitting with the second bearing sleeve 400. The first bearing sleeve 300 and the second bearing sleeve 400 are welded or integrally formed and fixed to the centers of the first side sealing plate 100 and the second side sealing plate 200, respectively, and aligned to ensure linear alignment when the pipe passes through the well body. The inner diameter matches the outer diameter of the pipe to be installed, and a guide chamfer is provided at the top for pipe insertion. The vibrating box 500 is a U-shaped metal... The casing is made of metal or rigid plastic, with the open end welded to the outer surface of the first side sealing plate 100. Multiple raised vibration strips 600 are evenly distributed on its inner wall to absorb the vibration energy of the pipeline. The outer wall is provided with vibration leveling strips 700, which transmit external impacts through elastic deformation. The rotating plate 801 is connected to the second side sealing plate 200 through a hinge. The fitting plate 802 can rotate 180° around the axis. The limiting block 803 provides locking at 0° and 90° positions, which facilitates adjustment of the operating space during installation. The sealing ring (120) is made of nitrile rubber and is embedded in the connecting groove of the first bearing sleeve 300, the second bearing sleeve 400 and the side sealing plate to form a double waterproof sealing barrier. The outer sealing gasket 130 is an elastic polyurethane gasket fitted on the outside of the first side sealing plate 100, which fits tightly with the well wall to prevent soil seepage into the connection port.
