Description

Technical Field

[0001] This utility model relates to the field of pipe jacking construction technology in municipal engineering, and more specifically, to a pipe used in pipe jacking construction in municipal engineering. Background Technology

[0002] Pipe jacking is a trenchless pipeline laying technology used in municipal construction. Pipe jacking utilizes the thrust of the main jacking cylinder and intermediate units to push the tool pipe or tunneling machine through the soil from the working shaft to the receiving shaft, where it is then lifted. Simultaneously, the pipeline following the tool pipe or tunneling machine is buried between the two shafts, thus achieving a trenchless method for laying underground pipelines.

[0003] However, existing pipe jacking construction pipelines have the following problems when being connected:

[0004] Existing pipe jacking construction for municipal engineering projects often involves pre-embedded parts on the preceding and following pipe sections. During pipe jacking, it is often necessary to rotate the two pipe sections to align the pre-embedded parts before connecting them. This process is cumbersome, requiring highly skilled construction personnel and prone to connection difficulties due to angular deviations. This significantly impacts construction efficiency, prolongs the construction period, makes construction extremely inconvenient, increases project costs, and seriously affects construction efficiency.

[0005] This utility model can achieve rapid and precise pipe connection by means of the smooth cooperation between the sliding groove and the moving block; it can achieve stable positioning of the moving block by relying on the precise matching of the positioning hole and the positioning rod; and it can greatly enhance the stability of the pipe connection through the coordinated operation of the fixed pipe, fixed end, insertion hole and embedded pipe, thus comprehensively improving the quality and efficiency of municipal engineering pipe jacking construction. Summary of the Invention

[0006] The present invention aims to solve the technical problems mentioned in the background art and provide a pipe for pipe jacking construction in municipal engineering.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a pipe for pipe jacking construction in municipal engineering, comprising: a pipe body, a movable block slidably connected to the surface of the pipe body, a fixed pipe embedded in the front of the movable block, the pipe body being composed of a left pipe and a right pipe, the fixed pipe being composed of a left sleeve and a right sleeve, a sliding groove being circumferentially formed on both the left and right sides of the surface of the left and right pipes, the sliding groove being slidably connected to the movable block, the left sleeve and right sleeve being respectively embedded in the front of the movable block slidably connected to the surface of the left and right pipes, the left end of the right sleeve being embedded inside the left sleeve, the left sleeve and right sleeve on the surface of the left and right pipes being arranged in opposite directions, and the left sleeve on the right pipe being embedded inside the right sleeve on the left pipe.

[0008] A further preferred embodiment: a positioning hole is provided on the right side of the groove on the right side of the pipe body surface, and the positioning hole is matched with the moving block.

[0009] A further preferred embodiment: a locking ring is fixedly installed on the front of the movable block, a fixing tube is embedded inside the locking ring, a second sliding groove is opened on the outer end face of the movable block, a movable plate is slidably connected in the second sliding groove, a positioning rod is fixedly installed on the back of the movable plate, and the positioning rod is matched with the positioning hole.

[0010] A further preferred embodiment: a limit block is fixedly installed on the outer end face of both the left and right sleeves, and a fixed end is fixedly installed on both the front and back sides of both the left and right sleeves, with a screw hole opened on the right end of each fixed end.

[0011] A further preferred embodiment: each of the left sleeves has an insertion hole at its outer end, and each of the right sleeves has an embedded tube fixedly installed at its outer end.

[0012] A further preferred embodiment: the embedding tube is embedded inside the socket. Beneficial effects

[0013] 1. By setting positioning holes and positioning rods, during the process of pushing the left and right pipes closer together and completing the connection of the fixed pipes during pipe jacking construction, when the moving block slides to the appropriate position, the moving plate in the second sliding groove on the outer end face of the moving block and the positioning rod on its back can be aligned with the positioning hole opened on the right side of the first sliding groove on the right side of the pipe body surface. The positioning rod is inserted into the positioning hole, thereby accurately positioning the position of the moving block on the pipe body, effectively preventing the moving block from sliding randomly along the first sliding groove during subsequent use, greatly improving the stability of the pipe connection, and thus ensuring the reliability of the entire pipe jacking construction process and subsequent use of the pipe, avoiding problems such as loosening and disconnection of pipe connections due to displacement of the moving block, and improving the quality and efficiency of municipal engineering pipe jacking construction;

[0014] 2. By setting up a fixed end, a socket, and an embedded tube, the embedded tube can be accurately embedded into the corresponding socket during pipe connection, achieving preliminary positioning and enabling the left and right sleeves to be initially connected. This greatly simplifies the connection process and reduces construction difficulty. At the same time, the screw hole on the fixed end allows for bolting after the embedded tube and socket have completed the preliminary connection, enhancing the integrity and stability of the connection. Throughout the construction and subsequent use, it effectively prevents the pipe connection from loosening or disengaging due to stress, ensuring the quality and efficiency of municipal engineering pipe jacking construction and guaranteeing the stable operation of the pipeline system.

[0015] 3. By setting up a sliding groove and a movable block, the movable block can slide freely within the sliding groove. This feature greatly facilitates pipe connection. When the left and right pipes of the pipe body are pushed closer to each other for docking, the movable block can move smoothly along the sliding groove, allowing the left and right sleeves of the fixed pipe to be accurately nested, achieving fast and precise docking. Furthermore, due to the sliding nature of the movable block, the relative position of the pipes can be flexibly adjusted during construction, reducing the accuracy requirements for the initial placement of the pipes, effectively improving construction efficiency, and reducing repeated adjustments caused by positional deviations during construction, providing strong support for the smooth progress of the entire pipe jacking construction.

[0016] 4. In summary, this type of pipe used in municipal engineering pipe jacking construction, through the arrangement of a sliding groove, positioning holes, a moving block, a positioning rod, a fixed pipe, a fixed end, a insertion hole, and an embedded pipe, allows the moving block to slide freely on the surface of the pipe body through the cooperation of the sliding groove and the moving block. When the left and right pipes are pushed closer, it facilitates the accurate nesting and docking of the left and right sleeves of the fixed pipe, reducing construction difficulty and improving docking efficiency. The positioning holes and positioning rods can accurately position the moving block when it slides to the appropriate position, preventing the moving block from sliding arbitrarily along the sliding groove during subsequent use and ensuring the stability of the pipe connection. The fixed pipe consists of left and right sleeves, and the embedded pipe at its outer end is initially positioned with the insertion hole during docking. The screw hole on the fixed end can be used with bolts for tightening, enhancing the integrity of the connection and preventing the pipe from loosening or disassembling due to stress during construction and subsequent use. The synergistic effect of all structures comprehensively improves the quality and efficiency of municipal engineering pipe jacking construction. Attached Figure Description

Detailed Implementation

[0021] The following will refer to the appendix in the embodiments of this utility model. Figures 1-3 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0022] Please see Figure 1-3 In this embodiment of the present invention, a pipe for pipe jacking construction in municipal engineering includes: a pipe body 1, a movable block 2 slidably connected to the surface of the pipe body 1, a fixed pipe 3 embedded in the front of the movable block 2, the pipe body 1 being composed of a left pipe 101 and a right pipe 102, the fixed pipe 3 being composed of a left sleeve 301 and a right sleeve 302, and sliding grooves 103 being slidably connected to the movable block 2 on both the left and right sides of the surfaces of the left pipe 101 and the right pipe 102. The movable block 2, which is slidably connected to the surface, has a left sleeve 301 and a right sleeve 302 embedded in its front side. The left end of the right sleeve 302 is embedded inside the left sleeve 301. The left sleeve 301 and the right sleeve 302 on the surfaces of the left pipe 101 and the right pipe 102 are arranged in opposite directions. The left sleeve 301 on the right pipe 102 is embedded inside the right sleeve 302 on the left pipe 101. A locking ring 201 is fixedly installed on the front side of the movable block 2. A fixing pipe 3 is embedded inside the locking ring 201. The movable block 2 is placed on the left pipe. On the grooves 103 on the surfaces of pipes 101 and 102, the movable block 2 can slide freely within the grooves 103. Simultaneously, the left sleeve 301 and right sleeve 302 are respectively embedded and installed on the front of their corresponding movable blocks 2, ensuring that the left end of the right sleeve 302 can be embedded inside the left sleeve 301. The left sleeve 301 and right sleeve 302 on the surfaces of the left and right pipes 101 and 102 face opposite directions. When the pipe jacking construction begins, the left and right pipes 101 are pushed closer together. During this approach, the left sleeve... Pipe 301 and right sleeve 302 are respectively connected to moving block 2 through locking ring 301. By utilizing the sliding characteristics of moving block 2 on slide groove 103, left sleeve 301 on right pipe 102 can be accurately embedded inside right sleeve 302 on left pipe 101, and vice versa, to complete the docking of fixed pipe 3. In the whole process, through the sliding cooperation between slide groove 103 and moving block 2, and the nesting design of left sleeve 301 and right sleeve 302, the connection steps of the pipe are effectively simplified and the construction efficiency is improved.

[0023] In this embodiment of the utility model, a positioning hole 104 is provided on the right side of the sliding groove 103 on the right side of the surface of the pipe body 1. The positioning hole 104 is matched with the moving block 2. A sliding groove 202 is provided on the outer end face of the moving block 2. A moving plate 203 is slidably connected in the sliding groove 202. A positioning rod 204 is fixedly installed on the back of the moving plate 203. The positioning rod 204 is matched with the positioning hole 104. When the left pipe 101 and the right pipe 102 are pushed closer to each other during the pipe jacking construction, the moving block 2 slides in the sliding groove 103 as the pipe moves. The left sleeve 301 on the right pipe 102 is embedded in the right sleeve 302 on the left pipe 101. At the same time, the left pipe 101... The right sleeve 302 is embedded inside the left sleeve 301 on the right pipe 102 to achieve the docking of the fixed pipe 3. When the moving block 2 slides to the appropriate position with the pipe docking, the moving plate 203 in the second slide groove 202 on the outer end face of the moving block 2 and the positioning rod 204 on its back are aligned with the positioning hole 104 opened on the right side of the first slide groove 103 on the right side of the pipe body 1. The moving plate 203 is pushed to slide in the second slide groove 202, and the positioning rod 204 is inserted into the positioning hole 104, thereby accurately positioning the position of the moving block 2 on the pipe body 1, preventing the moving block 2 from sliding randomly along the first slide groove 103 during subsequent use, and ensuring the stability of the pipe connection.

[0024] In this embodiment of the invention, limiting blocks 303 are fixedly installed on the outer end faces of both the left sleeve 301 and the right sleeve 302. Fixed ends 304 are fixedly installed on the front and back sides of both the left sleeve 301 and the right sleeve 302. Screw holes 305 are provided on the right ends of both fixed ends 304. Insertion holes 306 are provided on the outer ends of both the left sleeve 301 and the right sleeve 302. Embedded tubes 307 are fixedly installed on the outer ends of both the left and right sleeves. The embedded tubes 307 are embedded inside the insertion holes 306. During pipe jacking construction, when the left pipe 101 and the right pipe 102 are pushed closer together, the moving block 2 slides along the sliding groove 103. During this process, the embedded tube 307 on the right sleeve 302 gradually aligns with and embeds into the insertion hole 306 of the left sleeve 301. Simultaneously, the embedded tube 307 on the right sleeve 302 on the left pipe 101 also embeds into the left sleeve 301 on the right pipe 102. The connection of the fixed pipe 3 is initially achieved in the insertion hole 306. Since the outer end faces of the left sleeve 301 and the right sleeve 302 are both equipped with limit blocks 303, when the embedded pipe 307 is fully inserted into the insertion hole 306, the limit blocks 303 abut against each other, which initially restricts the relative position of the left sleeve 301 and the right sleeve 302, and prevents the left sleeve 301 and the right sleeve 302 from falling off the locking ring 201 and preventing them from moving excessively in the axial direction. Then, bolts are used to pass through the screw holes 305 on the front and back fixing ends 304 of the left sleeve 301 and the right sleeve 302 to further tighten the left and right sleeves together. The tightening force of the bolts enhances the integrity and stability of the connection part of the fixed pipe 3, ensuring that the pipe connection part will not loosen or disconnect due to force during the jacking construction and subsequent use.

[0025] Working principle: The movable block 2 is placed on the sliding groove 103 on the surface of the left pipe 101 and the right pipe 102, allowing it to slide freely; the left sleeve 301 and the right sleeve 302 are respectively embedded into the front of the corresponding movable block 2 through the locking ring 201, ensuring that the left end of the right sleeve 302 can be embedded into the interior of the left sleeve 301, and the two on the same side of the pipe face opposite directions. During pipe jacking construction, the left pipe 101 and the right pipe 102 are pushed closer to each other, and the movable block 2 slides in the sliding groove 103 as the pipes move. During this process, the right sleeve 301... The embedded tube 307 on 02 gradually aligns with and is inserted into the insertion hole 306 of the left sleeve 301. At the same time, the embedded tube 307 of the right sleeve 302 on the left pipe 101 is also inserted into the insertion hole 306 of the left sleeve 301 on the right pipe 102, thus initially achieving the docking of the fixed pipes 3. Utilizing the sliding characteristics of the moving block 2 on the slide groove 103, the left sleeve 301 on the right pipe 102 can be accurately inserted into the right sleeve 302 on the left pipe 101, and vice versa, further completing the docking of the fixed pipes 3. As the moving block 2 moves along the pipe... When the sliding block 2 slides to the appropriate position, the moving plate 203 and its positioning rod 204 in the second groove 202 on the outer end face of the moving block 2 align with the positioning hole 104 on the right side of the first groove 103 on the right side of the pipe body 1. This pushes the moving plate 203 to slide in the second groove 202, inserting the positioning rod 204 into the positioning hole 104, precisely positioning the moving block 2 on the pipe body 1, preventing it from sliding arbitrarily along the first groove 103. After the embedded tube 307 is fully inserted into the insertion hole 306, the left sleeve 301 and the right sleeve 30... The limiting blocks 303 on the outer end faces abut against each other, initially restricting their relative positions to prevent excessive movement in the axial direction and to prevent the left sleeve 301 and the right sleeve 302 from falling off the locking ring 201. Finally, bolts are used to pass through the screw holes 305 on the front and back fixing ends 304 of the left sleeve 301 and the right sleeve 302 to further tighten the connection between the left and right sleeves, enhancing the integrity and stability of the connection part of the fixed pipe 3, and ensuring that the pipe connection part will not loosen or disconnect due to stress during the jacking construction and subsequent use.
