Description

TECHNICAL FIELD

[0001] The present application relates to the field of pipe gallery, in particular to a waterproof pipe gallery structure. BACKGROUND

[0002] Many fields such as power, communication, gas, heating and water supply and drainage will involve various engineering pipelines and pipes. When the engineering pipelines and pipes are directly laid underground, the excavation of the road will cause damage to the engineering pipelines and pipes. When the engineering pipelines and pipes are directly exposed to the outside, they are easy to be damaged by human and prone to premature aging due to wind and sun.

[0003] At present, the pipe gallery as a kind of corridor for centralized arrangement of various engineering pipelines and pipes has been widely used. The pipe gallery can not only be erected in the air, but also can be buried underground, and the laying, increasing, decreasing and maintenance of the pipelines can be directly carried out in the pipe gallery, which is not only beautiful but also convenient for unified maintenance.

[0004] The engineering pipelines and pipes are relatively long, and the corresponding pipe gallery is also relatively long, so the normal whole pipe gallery is usually connected by each pipe body. The pipe gallery is required to have waterproof property because it is used to protect the internal pipes and pipelines, especially the underground pipe gallery needs to reduce the penetration of groundwater to the pipe gallery. The adjacent pipe bodies are relatively heavy and are not easy to rotate and move, which not only causes the splicing operation difficult, but also makes it difficult to complete the sealing and easy to cause the penetration of water at the splicing joint of the pipe body. SUMMARY

[0005] In order to facilitate the connection of two adjacent pipe bodies and reduce the possibility of water penetration at the connection of the pipe body in the pipe gallery, the present application provides a waterproof pipe gallery structure.

[0006] The waterproof pipe gallery structure provided by the present application adopts the following technical scheme:

[0007] A waterproof pipe gallery structure is formed by sequentially splicing a plurality of pipe bodies, and an outer sealing connection assembly is arranged at the connection of two adjacent pipe bodies, which comprises:

[0008] A shielding ring for sleeving at the splicing joint of two adjacent pipe bodies, the shielding ring being capable of sliding on the pipe body;

[0009] An elastic sealing ring is sleeved on each of the two adjacent pipe bodies, and the elastic sealing ring is located on both sides of the shielding ring;

[0010] A sliding cylinder is covered on each elastic sealing ring, and each sliding cylinder is capable of being threadedly connected with the shielding ring.

[0011] By adopting the technical scheme, since the pipe body is relatively heavy, the pipe body is inconvenient to rotate again when being placed into the pit by the crane, and the two pipe bodies are also inconvenient to rotate after being inserted and connected. The shielding ring is slid on the pipe body, and the shielding ring can be slid to the joint. The cantilever end of each pipe body is tightly sleeved with the elastic sealing ring and slid with the sliding cylinder, and the two elastic sealing rings are arranged between the opposite ends of the two sliding cylinders.

[0012] The sliding cylinders on the two pipe bodies are respectively slid to contact the two sides of the shielding ring, the sliding cylinders are rotated to be threadedly connected with the shielding ring, the sliding cylinder on the same pipe body is stopped when the end of the sliding cylinder and the elastic sealing ring abut against each other, and the elastic sealing ring seals the joint between the end of the sliding cylinder and the pipe body. The threadedly connected sliding cylinder and the shielding ring reduce the possibility of water seepage from the joint, and the shielding ring also seals the joint of the two pipe bodies, thereby reducing the possibility of water seepage from the joint. In addition, the sliding cylinder is rotated instead of the pipe body, so that the operation is more convenient and the implementability is high.

[0013] Optionally, the end wall of the elastic sealing ring abuts against one side of the shielding ring.

[0014] By adopting the technical scheme, the end wall of the elastic sealing ring seals the sliding cylinder and the pipe body, thereby reducing the possibility of water seepage from the end. The other end wall of the elastic sealing ring abuts against the shielding ring, the sealing ring pre-seals the gap between the shielding ring and the pipe body, thereby reducing the possibility of water seepage from the two sides of the shielding ring into the pipe body.

[0015] Optionally, the cylinder side wall of the sliding cylinder is connected with a flange arranged towards the pipe body, and the flange of the sliding cylinder corresponding to the elastic sealing ring is arranged on the side of the elastic sealing ring away from the joint.

[0016] By adopting the technical scheme, when the sliding cylinder is rotated to be threadedly connected with the shielding ring, since the height of the elastic sealing ring is not lower than the gap between the flange and the pipe body, the flange can abut against one end of the elastic sealing ring, thereby improving the sealing property of the pipe body and the end of the sliding cylinder and reducing the possibility of water seepage between the end of the sliding cylinder and the pipe body.

[0017] Optionally, the joint between the two adjacent pipe bodies is provided with a connecting structure, which includes a bolt.

[0018] By adopting the technical scheme, the bolt is arranged to fixedly connect the joint between the two adjacent pipe bodies, thereby reducing the possibility of mutual separation of the two pipe bodies along the length direction.

[0019] Optionally, a self-adhesive polymer waterproof layer is laid at the splice on the inner wall of the tube. The connection structure also includes an internal pressing mechanism that is linked to the pin. When the pin moves into the tube, the internal pressing mechanism presses the self-adhesive polymer waterproof layer. A locking nut is provided at the end of the pin located outside the tube.

[0020] By adopting the above technical solution, a self-adhesive polymer waterproof layer is set at the splice on the inner wall of the pipe, and a waterproofing measure is implemented at the splice from the inside of the pipe. This can further reduce the possibility of water seepage at the connection between the two pipes. The self-adhesive polymer waterproof layer is pressed by the internal pressing mechanism, which reduces the possibility of the self-adhesive polymer waterproof layer falling off the inner wall of the pipe.

[0021] Optionally, the internal clamping mechanism includes a fixing rod that passes through the self-adhesive polymer waterproof layer and is fixed to the inner wall of the tube, a bent rod that is hinged to one end of the fixing rod away from the inner wall of the tube, and a support rod that is hinged to the bend of the bent rod.

[0022] The head of the pin located inside the tube is provided with a lifting block, and the support rod and the lifting block are hinged together;

[0023] A clamping assembly is fixed to the end of the bent rod that is away from the fixed rod.

[0024] By adopting the above technical solution, when the pin moves into the tube, the lifting block moves inward and drives the support rod to rotate, which in turn drives the bending rod to rotate. This causes the side of the bending rod connected to the pressing component to move towards the inner wall of the tube and press against the inner wall of the tube, thereby pressing the self-adhesive polymer waterproof layer and making the self-adhesive polymer waterproof layer and the inner wall of the tube adhere more firmly.

[0025] Optionally, the clamping assembly includes a semi-ring that is fixedly connected to the fixing rod.

[0026] By adopting the above technical solution, the semi-ring is more suitable for the inner wall shape of the tube, and can better compress the tube. The semi-ring has a smaller curvature, making it easier to operate.

[0027] Optionally, multiple telescopic components are spaced apart on the semi-ring, and a pressure block is provided on the top of each telescopic component. An elastic element connects adjacent pressure blocks.

[0028] By adopting the above technical solution, the telescopic end of the telescopic component rotates under the reaction force of the inner wall of the tube, so that the top surface of the pressure block can better fit with the tube. The pressure blocks are connected by elastic elements, which can form a relatively adjustable arc and arc length, thereby adapting to the arc of the inner wall of the tube. At the same time, when the inner wall of the tube is uneven, the pressure block can also better adapt to the surface of the inner wall of the tube under the action of the telescopic component.

[0029] Optionally, the inner clamping mechanism is provided on both sides of the lifting block.

[0030] By adopting the above technical solution, when internal pressing mechanisms are provided on both sides, the self-adhesive polymer waterproof layer can be pressed from both sides of the splice, so that the self-adhesive polymer waterproof layer can be firmly sealed at the splice.

[0031] Optionally, the connecting structure is provided at both the upper and lower joints of the tube body.

[0032] By adopting the above technical solution, multiple connection structures can enable the clamping components in the inner clamping mechanism of each connection mechanism to work together to form a shape that fits the inner circle of the tube, thereby enabling the self-adhesive polymer waterproof layer to be clamped.

[0033] In summary, this application includes at least one of the following beneficial technical effects:

[0034] When the pipe body is heavy and inconvenient to rotate, a retaining ring can be installed to slide on the pipe body. This ring can be slid to the joint, and then sliding cylinders on both pipe bodies can be slid relative to each other until they press against the retaining ring. The sliding cylinders are then rotated to connect with the retaining ring via threads. When one end of the sliding cylinder on the same pipe body comes into contact with the elastic sealing ring, rotation of the sliding cylinder is stopped. This achieves a seal between the elastic sealing ring and one end of the sliding cylinder and the pipe body, as well as a seal at the connection between the sliding cylinder and the retaining ring. Furthermore, sealing the joint does not require rotating or moving the pipe body, making the operation very convenient and highly feasible. Attached Figure Description

[0047] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0048] This application discloses a waterproof pipe gallery structure.

[0049] Example 1

[0050] Reference Figure 1 A waterproof pipe gallery structure is described, consisting of multiple cylindrical pipes 1 sequentially spliced ​​together. An external sealing connection assembly 10 is provided at the joint of two adjacent pipes 1, which not only seals the joint and reduces the possibility of water leakage, but also allows for convenient sealing of adjacent pipes without rotating the pipes 1. The figure illustrates a case with two pipes 1, but is not limited to this configuration.

[0051] Please refer to the following: Figure 2 The external sealing connection assembly 10 includes sliding cylinders 13 and elastic sealing rings 12 fitted onto each pipe body 1. The sliding cylinders 13 on each pipe body 1 can slide relative to the pipe body 1, and the elastic sealing rings 12 on each pipe body 1 are in close contact with the pipe body 1. The sliding cylinders 13 are fitted outside the elastic sealing rings 12, and each of the two sliding cylinders 13 has a retaining flange 131 perpendicular to the pipe body 1 connected to its opposite end. The two elastic sealing rings 12 are located between the two retaining flanges 131. A blocking ring 11 that can slide relative to the two pipe bodies 1 is also fitted at the joint. The blocking ring 11 has external threads at both ends, and the sliding cylinders 13 on each pipe body 1 have internal threads on their inner walls. The two sliding cylinders 13 are respectively used for threaded connection to the two ends of the blocking ring 11.

[0052] One tube body 1 is provided with an annular insertion part, and the other tube body 1 is provided with an annular insertion groove for insertion of the annular insertion part.

[0053] The working principle of Embodiment 1 of this application is as follows: The pipe gallery in this embodiment can be laid underground or above ground, specifically underground. When the pipe gallery is laid underground, the opposite ends of the two pipe bodies 1 are cantilevered, that is, the bottom of the two opposite ends is hollowed out to facilitate the installation of the external sealing connection assembly 10. After the external sealing connection assembly 10 is installed, the hollowed-out part is filled in. One pipe body 1 has an annular insertion groove at its cantilever end, and the other pipe body 1 has an annular insertion part at its cantilever end.

[0054] Specifically, each of the two pipe bodies 1 is fitted with an elastic sealing ring 12 and a sliding cylinder 13. A shielding ring 11 is fitted onto the cantilever end of one pipe body 1, and the annular insertion part on the cantilever end of the other pipe body 1 is inserted into the shielding ring 11 and extends into the annular insertion groove of one pipe body 1, thus completing the splicing. The sliding cylinders 13 on the two pipe bodies 1 are slid relative to each other until they contact the shielding ring 11, and then the sliding cylinders 13 are rotated to make them threadedly connected to the shielding ring 11. When the sliding cylinder 13 on the same pipe body 1 abuts against the elastic sealing ring 12, that is, when the retaining flange 131 presses against one end of the elastic sealing ring 12, the rotation of the sliding cylinder 13 is stopped.

[0055] This achieves the sealing between one end of the sliding cylinder 13 and the pipe body 1 by the elastic sealing ring 12, and the threaded connection between the sliding cylinder 13 and the shielding ring 11 achieves the sealing between the two sliding cylinders 13 and the shielding ring 11.

[0056] Since the elastic sealing ring 12 is made of elastic material, it can be stretched and deformed to move closer to one side of the shielding ring 11. When the retaining flange 131 presses against one end of the elastic sealing ring 12 and the other end of the elastic sealing ring 12 touches the shielding ring 11, the rotation of the sliding cylinder 13 is stopped, which provides the best sealing effect at the joint. Alternatively, one end of the elastic sealing ring 12 can be pressed against one end of the shielding ring 11 initially, and the sliding cylinder 13 can be rotated until it presses against the other end of the elastic sealing ring 12. In this case, a lower degree of deformation of the elastic sealing ring 12 can be selected, thereby reducing the possibility of relative movement between the elastic sealing ring 12 and the pipe body 1 later.

[0057] After the two tubes 1 are joined together, the two sliding cylinders 13 can completely cover the shielding ring 11, or a portion of the shielding ring 11 can remain between the two sliding cylinders 13. The remaining portion of the shielding ring 11 can be directly opposite the joint or not. Figure 2 The image shows the situation directly opposite the splicing point.

[0058] Example 2

[0059] See Figure 3 , Figure 4 and Figure 5The difference between Embodiment 2 and Embodiment 1 is that: a connecting structure is provided at the splicing point of the two tubes 1, that is, a connecting structure is provided at the part where the annular plug part is inserted into the annular plug groove.

[0060] The connection structure includes a pin 20, which passes through the groove wall of the annular insertion slot and the annular insertion part in sequence to fix the two together.

[0061] Multiple pins 20 can be provided. This embodiment illustrates the case of two pins 20, which are arranged symmetrically vertically.

[0062] To reduce the possibility of water leakage at the joint between the two pipe bodies 1 of the utility tunnel, a self-adhesive polymer waterproof layer 2 is laid at the splice on the inner wall of the two pipe bodies 1, and the self-adhesive polymer waterproof layer 2 is laid along the length of the pipe body 1. The self-adhesive polymer waterproof layer 2 can be a waterproof membrane composed of a thermoplastic polyolefin resin, a pressure-sensitive polymer adhesive layer, and a granular layer with a common formulation. In short, any existing waterproof self-adhesive polymer waterproof membrane can be used.

[0063] The connecting structure also includes an internal clamping mechanism 30 that is linked to the pin 20. When the pin 20 moves into the tube body 1, the internal clamping mechanism 30 clamps the self-adhesive polymer waterproof layer 2. After the internal clamping mechanism 30 is installed and the self-adhesive polymer waterproof layer 2 is clamped, cement mortar can be applied to the self-adhesive polymer waterproof layer 2 for further fixation, or it can be left uncoated.

[0064] Specifically, the internal clamping mechanism 30 includes a vertically arranged fixing rod 31 that passes through the self-adhesive polymer waterproof layer 2 and is fixed to the inner wall of the tube body 1. An L-shaped bent rod 32 is hinged to one end of the fixing rod 31 away from the inner wall of the tube body 1. A horizontal support rod 33 is hinged to the bend of the horizontal and vertical rods of the bent rod 32.

[0065] The head of the pin 20 located inside the tube 1 is fixed with a lifting block 21, and the end of the support rod 33 away from the bend is hinged to the lifting block 21. The crossbar of the bent rod 32 extends away from the lifting block 21.

[0066] A clamping assembly 40 is fixed to one end of the crossbar of the bending rod 32 that is away from the lifting block 21.

[0067] The clamping assembly 40 includes a semi-ring 41 fixedly connected to a fixing rod 31. The fixing rod 31 is connected to the axial sidewall of the semi-ring 41. Multiple telescopic components 42 are spaced apart on the radial circumference of the semi-ring 41. A pressure block 43 is provided at the top of each telescopic component 42, and an elastic element 44, which is a spring, connects adjacent pressure blocks 43. The arc of the semi-ring can be less than or equal to 180 degrees.

[0068] The telescopic assembly 42 includes a hollow hinge cylinder 421 that is hinged to the radial circumferential surface of the semi-ring 41. A spring 422 is fixedly connected to the bottom wall of the hinge cylinder 421, and a telescopic rod 423 is connected to the end of the spring 422 that faces away from the bottom wall of the hinge cylinder 421. The telescopic rod 423 can slide inside the hinge cylinder 421, and a limiting part is provided at the end connected to the spring 422 to restrict the telescopic rod 423 from sliding out.

[0069] Each pressure block 43 is used to press against the self-adhesive polymer waterproof layer 2. When the pressure block 43 presses firmly against the self-adhesive polymer waterproof layer 2, multiple pressure blocks 43 and multiple elastic elements 44 form a semi-ring shape.

[0070] Please refer to the following: Figure 6 When the pressure block 43 is not tightly pressed against the self-adhesive polymer waterproof layer 2, multiple pressure blocks 43 can be parallel to the lifting block 21. Thus, as the pressure block 43 gradually approaches the self-adhesive polymer waterproof layer 2, one side of the pressure block 43 gradually contacts the inner wall of the tube body 1 and is pressed and rotated by the inner wall to conform to the curvature of the inner wall, thereby pressing the top surface of the entire pressure block 43 firmly against the self-adhesive polymer waterproof layer 2. One side of the pressure block 43 is the end that first contacts the inner wall of the tube body 1. When the pressure block 43 is located at both ends of the semi-ring 41, one side of the pressure block 43 is the end 431. When the pressure block 43 is located in the middle of the semi-ring 41, the top of the pressure block 43 can directly adapt to the curvature of the tube body 1, and is thus pressed against the self-adhesive polymer waterproof layer 2 by the reaction force of the inner wall of the tube body 1.

[0071] Both sides of the lifting block 21 are provided with an inner pressing mechanism 30, which can press the self-adhesive polymer waterproof layer 2 from both sides of the lifting block 21.

[0072] In order to compress the self-adhesive polymer waterproof layer 2, a connecting structure can also be set at the upper and lower joints of the pipe body 1.

[0073] The working principle of Embodiment 2 is as follows: the connecting structure is placed at the splice of the two pipe bodies 1 in the pipe gallery, so that the pin 20 passes through the groove wall of the annular insertion groove and the annular insertion part, and the part of the pin 20 extending out of the pipe body 1 is locked by the locking nut.

[0074] Gradually release the pin 20, causing it to move into the tube body 1, and the lifting block 21 also moves towards the axis of the tube body 1. Driven by the lifting block 21, the support rod 33 hinged to it rotates and drives the crossbar of the bending rod 32 to rotate, causing the side of the crossbar of the bending rod 32 connected to the pressing component 40 to move towards the inner wall of the tube body 1. At this time, one end 431 of the pressing block 43 first touches the inner wall of the tube body 1, and is pressed and rotated by the inner wall to conform to the curvature of the inner wall, thereby pressing the top surface of the entire pressing block 43 onto the self-adhesive polymer waterproof layer 2.

[0075] As each pressure block 43 gradually rotates, the inner wall of the tube 1 reacts on each pressure block 43, causing all pressure blocks 43 and all elastic elements 44 to form an arc surface as a whole. The arc surface formed as a whole together forms a pressing force on the self-adhesive polymer waterproof layer 2.

[0076] When both sides of the lifting block 21 are provided with an inner pressing mechanism 30, the self-adhesive polymer waterproof layer 2 can be pressed from both sides, and the gap at the splice is covered with the self-adhesive polymer waterproof layer 2. Due to the pressing of the inner pressing mechanism 30, the self-adhesive polymer waterproof layer 2 can better form a waterproof seal at the splice.

[0077] By setting multiple connection structures, the clamping components 40 in the inner clamping mechanism 30 of multiple connection mechanisms can be formed together to form a shape that fits the inner circle of the tube body 1, thereby enabling the self-adhesive polymer waterproof layer 2 to be clamped nearly 360 degrees.

[0078] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
