Description

Technical Field

[0001] This utility model relates to the field of trenchless pipeline repair construction, and in particular to a pipeline trenchless repair process inner lining pipe installation system. Background Technology

[0002] Trenchless pipeline repair is a technology that repairs or replaces existing pipelines without excavating or damaging the ground. Several construction techniques have been developed. One such technique is the stainless steel lining method, which involves installing a stainless steel lining inside the original pipeline and then grouting the wall to create a unified structure. This method offers good repair results and a long service life, and has already been applied in some projects. However, current construction methods require welding several pipe segments inside the original pipeline to form a welded lining in a dry environment. This necessitates interrupting pipeline operation or implementing temporary drainage measures to divert excess flow and ensure proper construction in a dry environment. On one hand, welding within the original pipeline is inconvenient due to space constraints; on the other hand, a central guide pipe needs to be installed before welding the segments to maintain pipeline operation; and on the other hand, the central guide pipe needs to be removed after welding to restore drainage. This results in significant construction difficulties, complex procedures, and a long construction period. Utility Model Content

[0003] The purpose of this utility model is to provide a pipeline trenchless repair process inner lining installation system to solve the problems of the difficulty of constructing inner linings by installing a conduit inside the pipeline for temporary drainage while the pipeline is in operation, thus keeping the original pipeline in a dry environment, and the complexity of the construction process and the long construction period caused by the need to install and remove the conduit before and after the segment welding.

[0004] To address the aforementioned technical problems, this utility model provides a trenchless pipeline repair process liner installation system, comprising: winches and hoisting equipment respectively arranged at the ground level of the upstream and downstream wells of the original pipeline to be repaired; a combined stainless steel liner located inside the original pipeline to be repaired; the combined stainless steel liner comprising several socket-connected liner sections; each liner section is provided with a liner support; the winch rope is connected to the liner support in the first liner section; multiple moving wheels for moving along the axial direction of the liner section are evenly arranged on the outer circumference of each liner section; lifting lugs for connecting to the hoisting equipment are provided on one end face of each liner section; when connecting two liner sections, a set of hoists is connected between the lifting lugs of adjacent liner sections, and another set of hoists is connected between the liner supports of adjacent liner sections.

[0005] Furthermore, the pipeline trenchless repair process liner installation system provided by this utility model includes the following structure for the socket-connected liner section: a clamp-type socket end is formed by thinning the inner wall of the previous liner section to the other end, and a spigot end is formed by thinning the outer wall of the subsequent liner section to the other end. The subsequent liner section is inserted into the socket end of the previous liner section through the spigot end for interference fit.

[0006] Furthermore, in the trenchless pipeline repair process lining pipe installation system provided by this utility model, the positions of the hoisting equipment and the winch are interchanged.

[0007] Furthermore, the pipeline trenchless repair process lining pipe installation system provided by this utility model has two or more sets of lining supports for each lining pipe section.

[0008] Furthermore, the trenchless pipeline repair process lining pipe installation system provided by this utility model has a temporary support set inside the original pipeline to be repaired at the upstream well, and a fixed pulley for winding the winch rope is set on the temporary support.

[0009] Furthermore, in the trenchless pipeline repair process lining pipe installation system provided by this utility model, the winch rope is connected to the lining support inside the first lining pipe section via a lifting ring or pulley.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] The pipeline trenchless repair process liner installation system provided by this utility model innovatively assembles the liner using several sections of liner with a socket connection structure. This allows for the installation of the liner while the pipeline is in operation and wet conditions are maintained. Compared to the traditional method of assembling the liner by welding pipe segments, it eliminates the need to install an additional conduit in the original pipeline for temporary discharge to create a dry environment for the liner installation. This avoids the installation and removal of the conduit, thereby simplifying the construction process, improving construction efficiency, and shortening the construction cycle.

[0012] The trenchless pipeline repair process liner installation system provided by this utility model uses a socket connection between adjacent liner sections. This ensures that the inner diameter of the assembled liner sections remains consistent. It also avoids the problem of limited working space for flange bolt connections when flanges are located on the outer wall of the liner section, which leads to construction difficulties. Furthermore, it avoids the problem of the flange being located on the inner wall of the liner section, which affects the drainage flow and easily causes blockages due to the accumulation of debris.

[0013] The trenchless pipeline repair process liner installation system provided by this utility model uses hoisting equipment to lower each liner section into the original pipeline to be repaired at the downstream well connection point. A winch then pulls the assembled liner sections to the upstream well, thus facilitating efficient relocation of the assembled liner sections. While the winch pulls the assembled liner sections, the moving wheels on each section move along the inner wall of the original pipeline to be repaired, reducing the difficulty of moving the assembled liner sections within the original pipeline. The moving wheels also serve as supports between the liner and the original pipeline, preventing the liner sections from directly contacting the inner wall of the original pipeline, thus avoiding difficulty in movement and damage to the liner sections. Furthermore, the moving wheels can also act as a framework between the liner and the original pipeline, being embedded in the concrete grout during backfilling, improving the construction quality of the backfilling process.

[0014] The pipeline trenchless repair process inner lining pipe installation system provided by this utility model supports the inner lining bracket in each inner lining pipe section, which can ensure the roundness of each inner lining pipe section and avoid deformation of the inner lining pipe section.

[0032] The present invention will now be described in detail with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0033] Please refer to Figures 1 to 17This utility model provides a trenchless pipeline repair process liner installation system 100, including: a winch 140 and a hoisting device 150 respectively arranged at the ground of the upstream and downstream wells 120 of the original pipeline 130 to be repaired; a combined stainless steel liner 160 located inside the original pipeline 130 to be repaired; the combined stainless steel liner 160 includes several socket-connected liner pipe sections 161, each liner pipe section 161 is provided with a liner support 170; the winch 140's winding rope 141 is connected to the first liner pipe section 161... The inner lining support 170 is connected within the lining pipe section 161. Multiple moving wheels 163 are evenly arranged on the outer circumference of each inner lining pipe section 161 for moving along the axial direction of the inner lining pipe section 161. Lifting lugs 162 for connecting with the hoisting equipment 150 are provided on one end face of each inner lining pipe section 161. When two inner lining pipe sections 161 are connected, a set of hoists is connected between the lifting lugs 162 of two adjacent inner lining pipe sections 161, and another set of hoists is connected between the inner lining support 170 of two adjacent inner lining pipe sections 161.

[0034] Please refer to Figures 1 to 17 This utility model embodiment also provides a method for installing an inner lining pipe in a trenchless pipeline repair process, including:

[0035] Step S1, please refer to Figure 1 A winch 140 is installed on the ground at the upstream well 110 of the original pipeline 130 to be repaired.

[0036] Step S2, please refer to Figure 1 A hoisting device 150 is arranged on the ground at the downstream manhole 120 of the original pipeline 130 to be repaired. Both the winch 140 and the hoisting device 150 employ known technologies. The figures only illustrate the general overview and do not depict the specific structure; they should not be considered as limitations on this embodiment. The ground level is only an example height and is typically on the same plane as the manhole covers of the upstream and downstream manholes 110 and 120. The upstream and downstream manholes 110 and 120 can be existing manholes of the original pipeline 130 to be repaired, or newly constructed manholes built on-site according to the length of the original pipeline 130. In this case, an opening needs to be made in the original pipeline 130 at the connection point between the newly constructed manhole and the original pipeline 130. The upstream manhole 110 only needs to allow for ventilation by opening the cover and the installation of the winch 140.

[0037] Step S3, please refer to Figures 5 to 7 , Figure 14 and Figure 17The stainless steel inner liner pipe 160 is divided into several inner liner pipe segments 161. Multiple moving wheels 163 are evenly arranged on the outer circumference of each inner liner pipe segment 161 for movement along the axial direction of the inner liner pipe segment 161. Lifting lugs 162 are provided on the outer circumference of each inner liner pipe segment 161, and an inner liner support 170 is installed inside each inner liner pipe segment 161 for support. The figure illustrates that each inner liner pipe segment 161 has eight evenly distributed moving wheels 163, arranged in pairs along a straight line at 1 / 5 of the circle of each inner liner pipe segment 161. This design ensures that the moving wheels 163 contact the inner wall of the original pipe 130 in four directions, preventing misalignment between the inner liner pipe segments 161 and the original pipe 130. Furthermore, the grouping of each moving wheel 163 ensures the stability of each inner liner pipe segment 161 during inward movement, avoiding height differences. To ensure the stability and safety of the hoisting, each inner lining pipe section 161 has two lifting lugs 162 arranged in a straight line. The lifting lugs 162 and the moving wheels 163 can be arranged together, forming a 5-equal division.

[0038] Step S4, please refer to Figure 1 and Figure 15 The hoisting equipment 150 lowers the first inner lining pipe section 161 to the downstream well 120 and places it in the original pipe 130 to be repaired by connecting the hoisting rope 151 to the hoisting lug 162. The hoisting rope 151 is then disconnected from the first inner lining pipe section 161, and the winch 140 is connected to the inner lining support 170 of the first inner lining pipe section 161 through the upstream well 110 and the original pipe 130 to be repaired.

[0039] Step S5, please refer to Figures 1 to 2 , Figures 15 to 16 The second inner lining pipe section 161 is hoisted and lowered into the downstream well 120 by connecting the hoisting rope 151 of the hoisting equipment 150 to the lifting lug 162. It is then placed in the original pipeline 130 to be repaired. The connection between the hoisting rope 151 and the second inner lining pipe section 161 is disconnected, and the second inner lining pipe section 161 is then connected to the first inner lining pipe section 161 by a socket joint.

[0040] Step S6, please refer to Figure 4 The lifting lug 162 of the first inner lining pipe section 161 is cut off. The winch 140 controls the winding rope 141 to pull the connected inner lining pipe section 161, and the moving wheel 163 propels the connected inner lining pipe section 161 within the original pipeline 130 to be repaired. The first inner lining pipe section 161 is moved upstream towards the upstream well 110 within the original pipeline 130, while the second inner lining pipe section 161 remains at the downstream well 120. If the inner diameter of the original pipeline 130 is larger than the outer end of the lifting lug, the lifting lug 162 may not need to be cut off.

[0041] Step S7, please refer to Figures 4 to 5 , Figures 16 to 17 The process involves repeatedly executing steps S5 and S6. The section of the inner lining pipe 161 already connected, located at the downstream well 120, is designated as the previous section of the inner lining pipe 161. The next section of the inner lining pipe 161 to be installed is designated as the subsequent section of the inner lining pipe 161. Steps S5 and S6 are repeated. The subsequent section of the inner lining pipe 161 is lowered into the downstream well 120 using the lifting lugs 162 connected to the lifting rope 151 of the hoisting equipment 150, and placed within the original pipeline 130 to be repaired. The connection between the lifting rope 151 and the subsequent section of the inner lining pipe 161 is then disconnected. The subsequent section of the inner lining pipe 161 is then connected to the previous section of the inner lining pipe using a socket joint. On pipe section 161, the lifting lug 162 of the previous inner lining pipe section 161 is cut off. The winch 140 controls the winding rope 141 to pull the connected inner lining pipe section 161, and the moving wheel 163 propels the connected inner lining pipe section 161 within the original pipe 130 to be repaired. The previous inner lining pipe section 161 is moved upstream towards the well 110 within the original pipe 130 to be repaired, while the next inner lining pipe section 161 remains at the downstream well 120. This process continues until the connected inner lining pipe section 161 covers the length of the original pipe 130 to be repaired, forming a combined stainless steel inner lining pipe 160. Each inner lining pipe section 161 in the combined stainless steel inner lining pipe 160 moves from the downstream well 120 towards the upstream well 110.

[0042] After the combined stainless steel liner 160 is installed inside the original pipe 130 to be repaired, backfill grouting is performed between the combined stainless steel liner 160 and the original pipe 130 to be repaired, making the original pipe 130 and the stainless steel liner 160 a whole, thereby achieving trenchless repair of the original pipe 130. To ensure the quality of grouting, the backfill areas at both ends of the combined stainless steel liner 160 are sealed before grouting, that is, the circumferential joints at both ends of the combined stainless steel liner 160 and the original pipe 130 are sealed to prevent grout leakage from both ends during grouting and to avoid affecting the grouting quality.

[0043] The pipeline trenchless repair process inner liner installation system 100 and method provided in this utility model innovatively assembles the inner liner using several sections of inner liner 161 with a socket connection structure, enabling the installation of the inner liner while the pipeline is in operation without interruption. Compared with the traditional method of assembling inner liner by welding pipe segments, it eliminates the need to set up an additional conduit in the original pipeline 130 for temporary discharge to create a dry environment for installing the inner liner, avoiding the installation and removal of the conduit, thereby simplifying the construction process, improving construction efficiency, and shortening the construction cycle.

[0044] The trenchless pipeline repair process liner installation system 100 and method provided in this utility model embodiment adopts a socket connection between adjacent liner pipe sections 161. On the one hand, this ensures that the inner diameter of the assembled liner pipe sections 161 remains consistent. On the other hand, it avoids the problem of limited working space for flange bolt connection when the flange is located on the outer wall of the liner pipe section 161, which leads to construction difficulties, when adjacent liner pipe sections 161 are connected by flanges. It also avoids the problem of affecting the drainage flow rate inside the liner pipe section 161 when the flange is located on the inner wall of the liner pipe section 161, which can easily cause blockage due to the accumulation of garbage and debris inside the liner pipe section 161.

[0045] The trenchless pipeline repair process liner installation system 100 and method provided in this embodiment of the utility model uses a hoisting device 150 to hoist and lower each liner section 161 into the original pipeline 130 to be repaired at the downstream well 120 connection point. A winch 140 then pulls the assembled liner sections 161 to the upstream well 110, thereby facilitating the efficient relocation of the assembled liner sections 161. During the hoisting of the assembled liner sections 161, the moving wheels on each liner section 161 facilitate the process. The 163 moves along the inner wall of the original pipe 130 to be repaired, reducing the difficulty of moving the assembled inner lining pipe section 161 within the original pipe 130. The moving wheel 163 can also serve as a support between the inner lining pipe and the original pipe 130, avoiding the problem that the inner lining pipe sections 161 are in direct contact with the inner wall of the original pipe 130 and are difficult to move, and that the inner lining pipe sections 161 are damaged. The moving wheel 163 can also serve as a skeleton between the inner lining pipe and the original pipe 130. During the back wall grouting, it is embedded in the concrete grout, improving the construction quality of the back wall grouting process.

[0046] The pipeline trenchless repair process inner lining pipe installation system 100 and method provided in this utility model embodiment supports the inner lining bracket 170 in each inner lining pipe section 161, which can ensure the roundness of each inner lining pipe section 161 and avoid deformation of the inner lining pipe section 161.

[0047] Please refer to this carefully. Figures 8 to 13 The pipeline trenchless repair process liner installation system 100 and method provided in this utility model embodiment, the method of connecting the subsequent liner section 161 to the previous liner section 161 in a socket-type manner includes:

[0048] At the socket connection, the inner wall of the preceding lining pipe section 161 is thinned to form a clamp-type socket end 1612, and the outer wall of the following lining pipe section 161 is thinned to form a spigot end 1611. The following lining pipe section 161 is inserted into the socket end of the preceding lining pipe section 161 through the spigot end 1611 to form an interference fit, thus forming a socket connection structure. The outer diameter of the lining pipe section 161 with the spigot end 1611 is equal to the inner diameter of the clamp-type socket end 1612, while the outer diameter of the clamp-type socket end 1612 is larger than the outer diameter of the pipe body of the lining pipe section 161. Therefore, at the connection between the two lining pipe sections 161, the clamp-type socket end 1612 ensures the wall thickness at the connection, guaranteeing the structural strength after connection and preventing grout leakage during subsequent grouting. The socket end 1612 maintains a certain distance to ensure that the outer diameter of the spigot end matches the inner diameter of the socket. The thinned section of the spigot end 1611 facilitates the alignment of the spigot end 1611 with the clamp-type socket end 1612, improving connection efficiency. Of course, without considering the need for greater structural strength at the connection between the two inner lining pipe sections 161, the inner and outer diameters of the two inner lining pipe sections 161 can remain unchanged; that is, the outer wall of the socket end 1612 has the same outer diameter as the inner lining pipe section 161. The thinning thickness can be 2mm. The total length of the spigot end 1611 can be 120mm, with the thinned and non-thinned sections each being 60mm. The inner length of the socket end 1612 can be 120mm, for a total length of 240mm. This ensures that the length of the inserted pipe section is equal to the inner length of the socket end 1612, improving the reliability and tightness of the connection.

[0049] Please refer to this carefully. Figure 2 , Figures 8 to 10 The trenchless pipeline repair process lining pipe installation system 100 and method provided in this embodiment of the utility model involves connecting a set of hoisting cranes 180 between the lifting lugs 162 of the front and rear lining pipe sections 161, and connecting another set of hoisting cranes 180 between the lining supports 170 of the front and rear lining pipe sections 161. The tension force of the two sets of hoisting cranes 180 is used to insert the rear lining pipe section 161 into the socket end of the front lining pipe section 161 through the spigot end 1611, forming an interference fit and a socket-type connection structure. The hoisting cranes 180 can be manual, electric, or a hinge can be used instead of a hoisting crane 180. The tightening force of the hoisting cranes 180 is used to insert and connect adjacent lining pipe sections 161 through the spigot end 1611 and the socket end 1612, forming an interference fit and a socket-type connection structure. The hoist 180 provides external force for the socket connection of two adjacent inner lining pipe sections 161, thereby reducing construction difficulty and avoiding problems such as unreliable or unsealed connections due to incomplete manual connection.

[0050] Please refer to Figure 4 and Figure 16To prevent the disengagement of adjacent inner liner pipe sections 161 during the upward pulling of the multi-section inner liner pipe section 161 via the winch 140 towards the upstream well 110, the pipeline trenchless repair process inner liner pipe installation system 100 and method provided in this embodiment of the invention involves circumferential spot welding at the inner joint of the preceding and following inner liner pipe sections 161 after the hoist 180 has tightened the connection. Since trenchless pipeline repair is typically carried out under low-flow conditions, there is no water flow in the upper part of the original pipeline 130; therefore, spot welding is preferentially performed on the upper part of adjacent inner liner pipe sections 161. The purpose of welding is to fix the socket-type connection structure and prevent adjacent inner liner pipe sections 161 from disengaging during movement; therefore, circumferential spot welding at equal intervals is sufficient, without the need for full welding. The winch 140 provides traction for the horizontal movement of the inner lining pipe section 161 after the socket connection. After splicing the inner lining pipe section 161 section by section, the winch continuously pulls the socket-connected inner lining pipe section 161 into the original pipe 130 to be repaired.

[0051] Please refer to Figure 7 and Figure 14 To ensure the roundness of each inner lining pipe section 161 and avoid deformation during hoisting, lowering, and horizontal movement, which would affect the reliability, sealing, and water flow of the connection, the pipeline trenchless repair process inner lining pipe installation system 100 and method provided in this utility model embodiment removes the inner lining support 170 of the first inner lining pipe section 161 when it is moved to the upstream well 110. That is, after the combined stainless steel inner lining pipe 160 is moved horizontally into place, that is, after all inner lining pipe sections 161 are installed and moved into the original pipeline 130, the inner lining support 170 of the first inner lining pipe section 161 can be removed. The inner lining supports 170 in the remaining inner lining pipe sections 161 are removed after the socket connection is completed and the sections are moved into the original pipeline 130.

[0052] To achieve the assembly and splicing of the combined stainless steel inner lining pipe 160, the pipeline trenchless repair process inner lining pipe installation system 100 and method provided in this utility model embodiment can adjust the hoisting equipment 150 to the upstream well 110, and use the hoisting equipment 150 to lower each inner lining pipe section 161 from the upstream well 110; adjust the winch 140 to the downstream well 120, and extend the winch rope 141 from the downstream well 120 into the inner lining support 170 of the first inner lining pipe section 161, and connect each inner lining pipe section 161 sequentially from the direction of the upstream well 110 to the direction of the downstream well 120.

[0053] Please refer to Figure 14 To ensure the overall roundness of the inner lining pipe section 161, the inner lining pipe installation system 100 and method for trenchless pipeline repair provided in this embodiment of the present invention can have two or more sets of inner lining supports 170 for each inner lining pipe section 161. The term "or more" includes the stated number.

[0054] Please refer to Figures 1 to 4 To prevent the winch 140 from eccentrically pulling on the connected inner lining pipe section 161, the trenchless pipeline repair process inner lining pipe installation system 100 and method provided in this embodiment of the utility model includes a temporary support 143 installed inside the original pipeline 130 to be repaired at the upstream well 110. A fixed pulley 142 is installed on the temporary support 143 to wind the winch 140's winding rope 141. Through the guiding action of the fixed pulley 142, the inner lining pipe section 161 after the socket connection is smoothly guided horizontally. To avoid eccentric pulling, the fixed pulley 142 can be aligned with the axis of the inner lining support 170.

[0055] Please refer to Figures 1 to 4 In order to improve the reliability and stability of the connection between the winding rope 140 and the inner lining support 170 in the first inner lining pipe section 161, the pipeline trenchless repair process inner lining pipe installation system 100 and method provided in this utility model embodiment connects the winding rope 141 of the winch 140 to the inner lining support 170 in the first inner lining pipe section 161 through a lifting ring or pulley.

[0056] The trenchless pipeline repair process lining pipe installation system 100 and method provided in this embodiment of the utility model can perform pipeline repair without interrupting pipeline operation and under water conditions, without the need for additional drainage or pipeline operation interruption measures. Adjacent lining pipe sections 161 adopt a socket connection structure, maintaining a certain distance at the socket end so that the inner diameter of the socket end is consistent with the outer diameter of the spigot end, thus achieving good connection effect and effectively preventing grout leakage during backfilling. After splicing, only partial spot welding is required for fixation, making it suitable for construction in water-filled pipeline environments.
