[0020] See also Figure 1-6 , an embodiment provided by the utility model:
[0021] A mud pipe structure based on synchronous construction of a communication channel and a shield machine comprises a shield tunnel 1, a support frame 11 is fixedly connected to the shield tunnel 1, a mud pipe body 12 is supported on the surface of the support frame 11, a first screw tube 2 is threadedly connected to the surface of the mud pipe body 12, a switching tube 21 is threadedly connected to the surface of the first screw tube 2, a second screw tube 22 is threadedly connected to the surface of the switching tube 21, a mud pipe joint body 23 is threadedly connected to the surface of the second screw tube 22, a horizontal straight line side where the mud pipe joint body 23 is located is the excavation location of the communication channel, the mud pipe joint body 23 reserves space for the communication channel, reduces the difficulty of excavating the communication channel, and improves the efficiency of excavating the communication channel.
[0022] Furthermore, a supporting mechanism is provided on the lower surface of the mud pipe joint body 23, and the supporting mechanism includes a fixing rod 3, which is fixedly connected to the lower surface of the mud pipe joint body 23, and a rotating block 31 is rotatably connected to the lower surface of the fixing rod 3, and a threaded barrel 32 is fixedly connected to the lower surface of the rotating block 31, and a screw 33 is threadedly connected to the bottom of the threaded barrel 32, and a supporting block 34 is fixedly connected to the bottom of the screw 33. Due to the excavation of the communication channel, the side of the mud pipe joint body 23 cannot be supported by the installation of the mud pipe joint body 23 on the side. The supporting mechanism supports the mud pipe joint body 23 at the bottom of the shield tunnel 1 to ensure the stability of the mud pipe joint body 23 and prevent the mud pipe joint body 23 from collapsing.
[0023] Furthermore, external threads are provided on the surfaces of the mud pipe body 12 and the mud pipe joint body 23, and external threads are also provided on both ends of the adapter tube 21. The adapter tube 21 is fixedly installed at one end of the shield tunnel 1 through the first screw tube 2, and the mud pipe joint body 23 is fixedly installed at the end of the adapter tube 21 away from the shield tunnel 1 through the second screw tube 22. The mud pipe joint body 23 connects the two groups of mud pipe bodies 12 together through the adapter tube 21, thereby realizing the transportation of waste materials such as mud and wastewater.
[0024] Furthermore, both ends of the mud pipe joint body 23 are inclined at forty-five degrees, and the two ends of the mud pipe joint body 23 are connected to the mud pipe body 12 through the transfer tube 21. The mud pipe joint body 23 and the mud pipe body 12 are overall in an "S" shape, and the mud pipe joint body 23 reserves sufficient space in the area of excavation of the communication channel on the shield tunnel 1.
[0025] Furthermore, the fixing rod 3 is in a "T" shape, the rotating block 31 rotates at the bottom of the mud pipe joint body 23 through the fixing rod 3, and the threaded barrel 32 rotates at the bottom of the mud pipe joint body 23 through the rotating block 31. The threaded barrel 32 needs to be rotated to a horizontal vertical at the bottom of the mud pipe joint body 23, so that the screw rod 33 is horizontally perpendicular to the horizontal plane, so that the threaded barrel 32 and the screw rod 33 can more effectively support the mud pipe joint body 23.
[0026] Furthermore, the screw 33 and the support block 34 rotate synchronously with the threaded barrel 32. The screw 33 rotates on the threaded barrel 32 to drive the screw 33 to extend and retract on the threaded barrel 32. The screw 33 approaches the surface of the shield tunnel 1 by extending and retracting. The screw 33 supports the threaded barrel 32 on the surface of the shield tunnel 1, and the threaded barrel 32 supports the mud pipe joint body 23.
[0027] Furthermore, the support block 34 is telescopically moved on the threaded barrel 32 by the screw 33, and the screw 33 drives the support block 34 on the threaded barrel 32 to contact the inner surface of the shield tunnel 1. The support block 34 is restricted at this time, so that the threaded barrel 32 and the screw 33 cannot rotate at the bottom of the mud pipe joint body 23.
[0028] Working principle: when it is necessary to excavate a communication channel on the side wall of the tunnel, the second screw tube 22 is rotated on the mud pipe joint body 23, so that the transfer tube 21 is installed on the mud pipe joint body 23 through the second screw tube 22, and the first screw tube 2 is rotated on the mud pipe body 12, so that the transfer tube 21 is installed on the mud pipe body 12 through the first screw tube 2. The mud pipe joint body 23 completes the docking with the two groups of mud pipe bodies 12 through the transfer tube 21. The mud pipe joint body 23 reserves enough space for the excavation area of the communication channel, which reduces the difficulty of excavating the communication channel and improves the efficiency of excavating the communication channel.
[0029] When the mud pipe joint body 23 is installed, the rotating block 31 rotates at the bottom of the mud pipe joint body 23 through the fixing rod 3, and the rotating block 31 drives the threaded barrel 32 to rotate at the bottom of the mud pipe joint body 23, so that the threaded barrel 32 rotates to a vertical horizontal plane at the bottom of the mud pipe joint body 23. At this time, the screw 33 is rotated at the bottom of the threaded barrel 32, so that the screw 33 drives the supporting block 34 to contact the surface of the shield tunnel 1. The supporting block 34 supports the mud pipe joint body 23 through the screw 33 and the threaded barrel 32, thereby improving the stability of the mud pipe joint body 23 during use.
