[0036] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.
[0037] like Figure 1 to Figure 4 As shown, the connecting channel fixing device 1 of the jacking method in the embodiment of the present application is used to connect the connecting channel 2 and the main tunnel 3, and the connecting channel 2 is connected to the main tunnel 3 through the jacking method connecting channel fixing device 1. The main tunnel 3 is provided with a through hole 31 that passes through the inside and outside of the main tunnel 3, and a pipe segment 32 is detachably connected to the through hole 31, and the pipe segment 32 can block the through hole 31. For example, the pipe segment 32 can be detachably connected to the through hole 31 by bolts.
[0038] The connecting channel fixing device 1 of the pipe jacking method comprises a first connecting pipe section 11 and a second connecting pipe section 12. The first connecting pipe section 11 can be connected to the hole wall of the through hole 31; the second connecting pipe section 12 is connected to the first connecting pipe section 11 and is coaxially arranged with the first connecting pipe section 11, the central axis of the first connecting pipe section 11 and the second connecting pipe section 12 is perpendicular to the central axis of the main tunnel 3, the second connecting pipe section 12 extends along its own axial direction to a side away from the main tunnel 3, and the connecting channel 2 is connected to an end of the second connecting pipe section 12 away from the main tunnel 3.
[0039] In a specific implementation, before installing the communication channel 2, the pipe segment 32 is connected to the through hole 31 and the through hole 31 is blocked to keep the main tunnel 3 in good integrity (such as Figure 1 and Figure 2 When constructing and installing the communication channel 2, first remove the pipe segment 32 to expose the through hole 31 on the main tunnel 3 for the pipe jacking machine 5 to pass through. Figure 3 Taking the position in the figure as an example, the pipe jacking machine 5 drives the communication channel 2 to move to the right until the pipe jacking machine 5 penetrates the through hole 31 and makes the communication channel 2 reach the preset position. At this time, there is a certain gap between the communication channel 2 and the main tunnel 3. Then the pipe jacking machine 5 is removed, the pipe jacking method communication channel fixing device 1 is connected to the main tunnel 3, and the communication channel 2 is connected to the pipe jacking method communication channel fixing device 1, that is: after removing the pipe jacking machine 5, first connect the first connecting pipe section 11 to the hole wall of the through hole 31, and then connect the communication channel 2 to the second connecting pipe section 12, so that the communication channel 2, the second connecting pipe section 12, and the first connecting pipe section 11 are all connected to the inside of the main tunnel 3.
[0040] The embodiment of the present application sets a detachable pipe segment 32 on the main tunnel 3, so that during the construction process, the pipe jacking machine 5 does not need to cut the main tunnel 3, but only needs to remove the pipe segment 32 in advance, and then connect the pipe jacking method communication channel fixing device 1 to the original position of the pipe segment 32, and finally connect the communication channel 2 to the pipe jacking method communication channel fixing device 1 to complete the installation construction of the communication channel 2. In this way, it can avoid the adverse effect of cutting on the structure of the main tunnel 3, and at the same time, the pipe jacking method communication channel fixing device 1 is set as a special connecting piece, which is conducive to reducing the difficulty of connection construction and improving connection stability.
[0041] Optionally, the first connecting pipe section 11 and the second connecting pipe section 12 are integrally formed. In this way, not only is the processing and manufacturing of the pipe jacking method communication channel fixing device 1 convenient, but also the steps of installing and connecting the pipe jacking method communication channel fixing device 1 are simplified, which is conducive to improving construction efficiency.
[0042] Specifically, the first connecting pipe section 11 can be detachably connected to the hole wall of the through hole 31 to facilitate subsequent maintenance and replacement of the communication channel fixing device 1 using the jacking method.
[0043] Furthermore, if Figures 4 to 6 As shown, the first connecting pipe section 11 has a mounting flange 111, which is radially protruding relative to the second connecting pipe section 12, and the mounting flange 111 is detachably connected to the hole wall of the through hole 31. That is, the radial dimension of the first connecting pipe section 11 is larger than the radial dimension of the second connecting pipe section 12, so that the connection area between the first connecting pipe section 11 and the main tunnel 3 is larger, which is conducive to improving the connection stability. In addition, the mounting flange 111 provides a clear position for the connection operation, which is conducive to improving the convenience of the first connecting pipe section 11 during installation and connection, and is convenient for operators to construct.
[0044] For example, the mounting flange 111 may be connected to the through hole 31 by bolts.
[0045] like Figure 4 As shown, in some embodiments, a grouting port 121 is provided on the pipe wall of the second connecting pipe section 12, and the grouting port 121 is used to inject grout into the connection between the first connecting pipe section 11 and the main tunnel 3. In this way, the gap between the first connecting pipe section 11 and the main tunnel 3 can be filled by grouting, which is beneficial to improving the integrity and stability of the connecting channel fixing device 1 of the jacking method when it is installed on the main tunnel 3.
[0046] Optionally, two grouting ports 121 are provided, and the two grouting ports 121 are arranged at intervals along the circumference of the second connecting pipe section 12. In this way, the slurry can enter the gap between the first connecting pipe section 11 and the main tunnel 3 from two directions, which is conducive to making the slurry more evenly distributed.
[0047] Of course, the number of the grouting ports 121 is not limited to two. In other embodiments, the number of the grouting ports 121 may also be four, and the four grouting ports may be evenly arranged along the circumference of the second connecting pipe section 12 .
[0048] Optionally, the communication channel 2 and the second connecting pipe section 12 are detachably connected to facilitate subsequent maintenance and replacement of the communication channel 2 .
[0049] Specifically, Figure 4 and Figure 7 As shown, a plug-in structure 4 is provided between the communication channel 2 and the second connection pipe section 12, and the plug-in structure 4 includes a socket joint 41 and a socket 42. The socket joint 41 is provided on one of the communication channel 2 and the second connection pipe section 12, and the socket 42 is provided on the other of the communication channel 2 and the second connection pipe section 12. The socket joint 41 and the socket 42 are plugged in and matched. In this embodiment, the socket joint 41 is provided on the second connection pipe section 12, and the socket 42 is provided on the communication channel 2. In specific implementation, it is only necessary to align the socket joint 41 and the socket 42 and gradually approach them until the two are plugged in and matched, and the operation is simple and quick.
[0050] Of course, in other embodiments, the communication channel 2 and the second connecting pipe section 12 may also be detachably connected in the form of a threaded connection or a flange connection.
[0051] like Figure 4As shown, in some embodiments, the communication channel fixing device 1 of the jacking method further includes an auxiliary installation component 13, the auxiliary installation component 13 includes a first lifting ear 131, a second lifting ear 132 and a pull rope 133, the first lifting ear 131 is fixedly arranged on the inner wall of the first connecting pipe section 11, the second lifting ear 132 is fixedly arranged on the inner wall of the communication channel 2, and the two ends of the pull rope 133 are respectively connected to the first lifting ear 131 and the second lifting ear 132, and the pull rope 133 is used to apply force to the second lifting ear 132 to pull the communication channel 2 to move to the side close to the first connecting pipe section 11. In this way, the communication channel 2 can be more firmly connected to the communication channel fixing device 1 of the jacking method under the action of the pull rope 133.
[0052] Specifically, an electric hoist may be provided to be connected to the pull rope 133 so that the pull rope 133 can be moved under the drive of the electric hoist.
[0053] Optionally, there are two groups of auxiliary installation components 13, and the two groups of auxiliary installation components 13 are arranged at intervals along the circumference of the communication channel 2. The two groups of auxiliary installation components 13 can be symmetrically arranged to evenly apply force to all parts of the communication channel 2 to prevent the position of the communication channel 2 from being deflected relative to the communication channel fixing device 1 of the jacking method.
[0054] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the claims of the present invention.
