Description

Technical Field

[0001] The utility model relates to a jacking pipe, in particular to an F-shaped steel socket-type jacking pipe, belonging to the technical field of pipeline connection. Background Art

[0002] F-type steel socket-type jacking pipe is a pipe widely used in municipal drainage pipeline projects. Its unique design and superior performance make it an ideal choice for jacking construction. One end of the F-type steel socket-type jacking pipe is pre-buried with a socket steel ring. Half of the steel ring is buried in concrete (along the outer diameter), and the other half is extended outward to form a socket; the other end is made into a shrinkage deformation socket that matches the steel ring. During installation, the steel ring is used as a socket connection plate. This design allows the pipe to have a larger deflection angle when connected and better resistance to foundation deformation and leakage.

[0003] However, when installing traditional F-shaped steel socket-type jacking pipes, the two adjacent jacking pipe bodies are fixed only by the steel ring and the socket connection, and there is a lack of limit components. When installing the jacking pipe, a jacking machine or other jacking equipment is required to gradually push the pipe into the ground, causing the two adjacent jacking pipes to be easily loosened by external force during the jacking process, thereby reducing the overall stability of the pipeline system.

[0025] As a technical optimization solution of the present invention, the cross-section of one end of the slider 503 facing the limiting groove 504 is a trapezoidal structure, and the two sliders 503 are symmetrically arranged about the middle part of the top tube body 1. Two first guide rods 505 are fixedly connected in the mounting sleeve 501, and two guide grooves 506 are provided on the slider 503, and the first guide rods 505 are slidably connected to the guide groove 506; the end of the slider 503 facing the limiting groove 504 is a trapezoidal structure, which facilitates the slider 503 to quickly engage into the limiting groove 504. The setting of the first guide rod 505 has a guiding effect on the slider 503, so that the sliding of the slider 503 is more stable.

[0026] As a technical optimization solution of the present invention, the cross-section of the first guide rod 505 is T-shaped, and a slot 507 is provided at the top of the screw rod 502. The slot 507 is hexagonal, which is convenient for using a hexagonal wrench to rotate the screw rod 502. The T-shaped cross-section of the first guide rod 505 has an anti-slip effect on the slider 503.

[0027] As a technical optimization solution of the present invention, a first groove 7 is provided on one end of the jacking pipe body 1 facing the steel ring 2, and a first rubber ring 8 is installed on the end of the socket 3 facing away from the jacking pipe body 1, and the first rubber ring 8 is engaged with the first groove 7.

The arrangement of the first rubber ring 8 and the second rubber ring 10 increases the friction between the socket 3 and the jacking pipe body 1 and the steel ring 2, so that the sealing between the socket 3 and the jacking pipe body 1 and the steel ring 2 is better, which can effectively prevent leakage at the connection between the two jacking pipe bodies 1.

The setting of the protective plate 601 can play a good protective role on the limiting structure 5.

[0029] As a technical optimization solution of the present invention, a second guide rod 602 is fixedly connected to the steel ring 2, and the protective plate 601 is slidingly connected to the second guide rod 602; the second guide rod 602 has a good guiding effect on the protective plate 601, making the sliding of the protective plate 601 more stable.

[0030] When the utility model is used, the first rubber ring 8 is first installed on the end surface of the socket 3 facing away from the steel ring 2, and then the second rubber ring 10 is installed on the side wall of the socket 3. The arrangement of the first rubber ring 8 and the second rubber ring 10 increases the friction between the socket 3 and the jacking pipe body 1 and the steel ring 2, so that the sealing performance between the socket 3 and the jacking pipe body 1 and the steel ring 2 is better, which can effectively prevent leakage from occurring at the connection between the two jacking pipe bodies 1; then use the bolt 4 to install the installation sleeve 501 on the steel ring 2, and then after the first jacking pipe body 1 is installed in the designated position, the second rubber ring 10 is installed. The socket 3 of each jacking tube body 1 is aligned with the steel ring 2 on the first jacking tube body 1, and then the second jacking tube body 1 is pushed toward the steel ring 2. The jacking tube body 1 drives the socket 3 to move into the steel ring 2, so that the first rubber ring 8 is engaged with the first groove 7, and the second rubber ring 10 is engaged with the second groove 9, so that the socket 3 is plugged into the steel ring 2, thereby completing the preliminary installation of the jacking tube body 1; then, the hexagonal wrench is inserted into the slot 507, and the hexagonal wrench is rotated. The hexagonal wrench drives the screw rod 502 to rotate, and the screw rod 502 thread drives the slider 503 toward the socket 3 slides, so that the slider 503 is engaged in the limiting groove 504, further limiting the socket 3, preventing the jacking machine from loosening the jacking body 1 during the jacking process, effectively preventing leakage at the connection of the jacking body 1, thereby improving the overall stability of the pipeline system; the setting of the first guide rod 505 has a guiding effect on the slider 503, making the slider 503 slide more stably, and the end of the slider 503 facing the limiting groove 504 is a trapezoidal structure, which facilitates the slider 503 to quickly engage in the limiting groove 504; the mounting sleeve 501 is bolted 4 is installed on the steel ring 2, making the installation and removal of the installation sleeve 501 more convenient and facilitating later maintenance and replacement; when the jacking tube body 1 needs to be disassembled, the protective plate 601 is pushed to slide on the steel ring 2, so that the protective plate 601 no longer blocks the installation sleeve 501, and at the same time, the protective plate 601 resists the spring 603 to shrink, and then the screw rod 502 is rotated to make the screw rod 502 thread drive the slider 503 to slide out of the limiting groove 504, thereby releasing the limit on the jacking tube body 1. The setting of the protective plate 601 can play a good protective role on the limiting structure 5.
