[0036] At present, due to the increasingly scarce urban ground space resources, there is a consensus on the development of underground space to meet the needs of urban functions. The existing development of underground space has gradually evolved into a spatial and networked form. To achieve the interconnection of the underground space network, a large number of T-junction tunnels need to be constructed. After a large number of tests and operations, the construction of the T-junction connecting passage not only has the characteristics of full enclosure, micro reinforcement, and strong support, but also can achieve the effect of fully mechanized construction in a narrow space. However, in the traditional T-junction connecting passage construction using pipe jacking for cutting, since most of the segments are arc-shaped surfaces, it is difficult to solve the problems of the pipe jacking attitude and axis deviation during the tunneling process. Therefore, how to accurately control the pipe jacking attitude and axis when connecting two tunnels is a problem that needs to be solved by those skilled in the art at present.

[0037] The technical solutions of this embodiment will be further described below with reference to the accompanying drawings and through specific implementation manners.

[0038] As Figures 1-7 shown, this embodiment provides a mechanical method connecting passage construction device for pipe jacking construction between a first tunnel 100 and a second tunnel 200. The mechanical method connecting passage construction device includes a cutter head assembly 10, a receiving box 20, and a control system 30. The cutter head assembly 10 includes a cutter head 12, and the cutter head 12 can cut through the side wall of the first tunnel 100 or the second tunnel 200. The cutter head assembly 10 is disposed on one side of the receiving box 20, and the other side of the receiving box 20 is disposed in the first tunnel 100 or the second tunnel 200. The control system 30 is disposed on the receiving box 20 and is located on both sides of the cutter head assembly 10 for adjusting the advancing attitude of the cutter head assembly 10.

[0039] Specifically, in this embodiment, the cutter disc 12 in the cutter disc assembly 10 can cut the inner wall of the tunnel to achieve connectivity. At the same time, the control system 30 arranged on both sides of the cutter disc 12 can adjust the excavation posture of the cutter disc assembly 10. Combined with the adaptability of the cutter disc 12 to the arc surface of the tunnel segment, the cutting stability is guaranteed, the situation of concentrated stress between the segment and the tunnel segment in conventional operations is avoided, and the problem of deviation of the axis of the jacking operation is solved. When deviation occurs, the excavation direction and position of the cutter disc 12 can be adjusted by the control system 30, so that it always maintains the same direction for excavation, so as to improve construction accuracy and operation efficiency.

[0040] The specific structure of the mechanical communication channel construction device in this embodiment is described below.

[0041] like Figures 1-3 As shown, the mechanical method communication channel construction device in this embodiment includes a cutterhead assembly 10, a housing box 20 and a control system 30. Optionally, the cutterhead assembly 10 is rotatably arranged on the housing box 20, and the control system 30 is also arranged on the housing box 20 and located on both sides of the cutterhead assembly 10 to adjust the excavation posture of the cutterhead assembly 10, thereby adjusting the axis deviation between the cutterhead assembly 10 and the tunnel in which it is located under the action of the control system 30, and through the adaptability of the cutterhead assembly 10 and the inner wall of the tunnel, it is possible to avoid the generation of concentrated force, thereby ensuring the stability and efficiency of the construction.

[0042] Combination Figure 4 and Figure 5 As shown, in this embodiment, the cutterhead assembly 10 includes a driving wheel 11, a cutterhead 12 and a motor 101. Optionally, the cutterhead 12 can penetrate the side wall of the tunnel, so that it can perform pipe jacking operations between adjacent tunnels to open up the tunnel for subsequent installation of contact parts. Further, in this embodiment, the driving wheel 11 is engaged with the outer side of the cutterhead 12, and the motor 101 is used to drive the driving wheel 11, so that the driving wheel 11 is driven by the motor 101, and then the cutterhead 12 is driven to rotate to achieve pipe jacking construction. Further, the driving wheel 11 and the motor 101 are both placed in the receiving box 20, and the half side of the cutterhead 12 engaged with the driving wheel 11 is located in the receiving box 20, and the other half side of the cutterhead 12 extends out of the receiving box 20 to perform cutting and excavation construction on the tunnel and its outer side. Exemplarily, in this embodiment, the cutterhead 12 can ensure stable advancement during pipe jacking operations by traction jacking or controlling the power of the jack, and the cutterhead 12 can rotate clockwise or counterclockwise respectively under the action of the driving wheel 11, so as to meet the use requirements. Furthermore, in the present embodiment, the cutter head 12 is configured as a cylindrical structure, so as to ensure the adaptability of the tangential arc surface of the pipe segment and reduce concentrated stress.

[0043] Further, the accommodation box 20 includes a slurry inlet pipe 21, a slurry discharge pipe 22, and a slurry and soil chamber 201. Optionally, the slurry inlet pipe 21 is used to introduce slurry, and the control system 30 can control the slurry to be sprayed towards the cutter head 12 in different directions, thereby adjusting and controlling the working attitude of the cutter head 12. The slurry discharge pipe 22 is used to discharge the muck. Thus, through the combined action of the slurry inlet pipe 21 and the control system 30, the operation attitude of the cutter head 12 can be adjusted to avoid the influence caused by the axis deviation. And under the action of the slurry discharge pipe 22, the muck and the sprayed slurry generated during the tunneling process can be discharged from the accommodation box 20 in time to avoid congestion and affect the operation of the cutter head 12. Exemplarily, both the slurry inlet pipe 21 and the slurry discharge pipe 22 are communicated with the slurry and soil chamber 201. Thus, during the rotation of the cutter head 12, the muck and other cut materials can be stored in the slurry and soil chamber 201 and discharged through the slurry discharge pipe 22 to ensure the cleanliness of the construction environment.

[0044] As Figure 4 shown, in this embodiment, the control system 30 includes an electric valve 31, a booster pump 32, and a controller 33. Optionally, in this embodiment, several electric valves 31 are provided and symmetrically arranged on both sides of the cutter head 12. The electric valve 31 and the booster pump 32 are both electrically connected to the controller 33 to adjust and control the forward attitude of the cutter head. Specifically, in this embodiment, eight electric valves 31 are provided, and every four form a group. The two groups of electric valves 31 are respectively arranged outside the accommodation box 20 and on both sides of the cutter head 12, so as to avoid being contaminated by slurry, etc. inside the accommodation box 20 while not affecting the operation of the cutter head 12. Specifically, at least one booster pump 32 is correspondingly arranged for each group of electric valves 31. Thus, the booster pump 32 can spray the slurry introduced by the slurry inlet pipe 21 at different positions and in different directions. And due to the position setting of the booster pump 32, the slurry can be sprayed on the opposite sides of the cutter head 12 as needed, and then pressure is applied to both sides of the cutter head 12 to change its tunneling attitude, so as to achieve the effect that the attitude of the cutter head 12 and the axis deviation are controllable during the pipe jacking construction process. Exemplarily, the controller 33 is set as an STM32 controller, and at least one controller 33 is provided in this embodiment. All the electric valves 31 and booster pumps 32 are electrically connected to the controller 33. Thus, under the action of the controller 33, the forward attitude of the cutter head 12 during the pipe jacking operation can be adjusted in real time.

[0045] Combined Figure 6 and Figure 7As shown in the figure, in this embodiment, the mechanical connection passage construction device further includes a fixing member 40 and a telescopic member 50, and is mainly used for pipe jacking construction between the first tunnel 100 and the second tunnel 200. Specifically, the fixing member 40 is fixed to the inner wall of the first tunnel 100 or the second tunnel 200 and is connected to one side of the receiving box 20, so as to fix the receiving box 20 in the first tunnel 100 or the second tunnel 200. Further, a telescopic member 50 is provided between the receiving box 20 and the fixing member 40, and the receiving box 20 is connected to the fixing member 40 through the telescopic member 50, whereby the receiving box 20 is telescopically connected to the inner wall of the first tunnel 100 or the second tunnel 200, so that the cutter head 12 can continuously move forward during the tunneling process. Specifically, the cutter head assembly 10 can penetrate the side wall of the first tunnel 100 or the second tunnel 200, and the opposite sides of the receiving box 20 are respectively connected to the cutter head assembly 10 and are telescopically arranged in the first tunnel 100 or the second tunnel 200, so that the cutter head assembly 10 preferentially contacts the side wall of the first tunnel 100 or the second tunnel 200 and cuts it during the tunneling process. Exemplarily, the outer arc of the cutter head 12 is adapted to the inner arc of the first tunnel 100 or the second tunnel 200, so as to have a high adaptability with the tunnel inner wall, realize the cooperation of the arc surface and the arc surface, and further make the tunnel segment float and fit with the cutter head 12, effectively solving the problem of concentrated force generated in the traditional method and improving its cutting effect. Further, in this embodiment, the control system 30 can adjust the axis of the blade 12 to be parallel to the axis of the first tunnel 100 or the second tunnel 200, so as to ensure the stability of the construction attitude, reduce the deviation value of the axis, realize the controllable effect, and improve the construction accuracy and operation efficiency. Exemplarily, in this embodiment, the mechanical connection passage construction device is placed in the second tunnel 200 and gradually tunnels to the first tunnel 100 from the inside of the second tunnel 200. By using the special design of the cutter head assembly 10 and the cooperation of the control system 30, the adaptability of the segment arc surface and the control problems of the tunneling attitude and axis deviation during construction can be solved, realizing the precise control of the attitude and axis during the pipe jacking construction process, and making the construction more stable and efficient.
