[0019] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0020] According to an embodiment of the present invention, the integrated tunneling and assembly connecting passage construction system includes a tunneling device, a propulsion device, and a material conveying device. The tunneling device includes a water-cooled drill 1, a movable platform 2, and a height adjustment device 4. A rotating track 3 is provided on the top of the movable platform 2, and the water-cooled drill 1 is slidably connected to the rotating track 3. The height adjustment device 4 is arranged on the water-cooled drill 1 to adjust the drilling height of the water-cooled drill 1. The propulsion device includes a first lifting platform 5, a second lifting platform 6, a support shield 8, a segment assembly machine 9, and a muck transport chute 7. The first lifting platform 5 is adjacent to the tunnel face, and the second lifting platform 6 is adjacent to the main tunnel section. The tensioning shield 8 is arranged between the first lifting platform 5 and the second lifting platform 6. The segment assembly machine 9 is arranged on the tensioning shield 8 to assemble the segments. The tensioning shield 8 is used to provide the segment assembly reaction force. The muck transport chute 7 passes through the center of the tensioning shield 8 and extends along the axial direction of the tunnel. The two ends of the muck transport chute 7 are connected to the first lifting platform 5 and the second lifting platform 6 respectively to transport muck. The material conveying device includes a transport trolley 12 and a supporting trolley 10. The top of the supporting trolley 10 is equipped with a material hoist 11, and the bottom of the supporting trolley 10 is equipped with a transport flatbed trolley 13. The supporting trolley 10 is arranged in the main tunnel of the tunnel, and the transport trolley 12 is arranged below the segment assembly machine 9.

[0021] The water-cooled drill 1 is used to drill holes in the tunnel rock wall, providing access for subsequent excavation operations. The rotation and propulsion of the water-cooled drill 1 efficiently breaks up the rock. A movable platform 2 serves as a support platform for the water-cooled drill 1 and can move along the tunnel axis to adapt to different excavation needs. A rotating track 3 at its top allows the water-cooled drill 1 to move along the track, achieving more accurate drilling operations. By adjusting the drilling height of the water-cooled drill 1, it can adapt to tunnels with different cross-sectional shapes and sizes. The height adjustment device 4 can be a hydraulic cylinder, electric actuator, or other mechanical device capable of precisely controlling the raising and lowering of the water-cooled drill 1. A first lifting platform 5 is located near the tunnel face and is used to support and adjust the height and position of the excavation device, ensuring that the device can accurately align with the face for excavation. A tensioning shield 8 is positioned between the first lifting platform 5 and the second lifting platform 6 to tension the tunnel rock wall, providing reaction force support for segment assembly. A muck transport chute 7 passes through the center of the tensioning shield 8 and extends along the tunnel axis to transport the muck generated during excavation. The two ends of the slag transport chute 7 are connected to the first lifting platform 5 and the second lifting platform 6 respectively, to ensure that the slag can be smoothly discharged from the tunnel.

[0022] The segment crane 22 is used to transport tunnel segments. Its main function is to lift and transport tunnel segments to the segment assembler 9, providing segments for the assembler. The segment crane 22 can also assist in muck removal operations. Muck generated during tunneling can be lifted and transported by the segment crane 22, facilitating subsequent muck removal work.

[0023] The segment crane 22 lifts segments from the storage area using a hook or grabbing device, moves them along the main beam to the vicinity of the segment assembler 9, and then places the segments in the assembly position. The segment crane 22 can quickly and accurately transport segments from the storage area to the vicinity of the segment assembler 9, reducing the time and workload of segment transportation and improving the efficiency of segment assembly. The segment crane 22 also assists in muck removal, promptly clearing away the excavated soil generated during tunneling and preventing soil accumulation from affecting the construction progress. This integrated lifting method optimizes the construction process and improves construction continuity.

[0024] In some embodiments, a slag bin 15 is arranged on the first lifting platform 5.

[0025] Specifically, the waste container 15 is used to collect small pieces of waste soil, while larger pieces are transferred via the waste soil transport chute 7. The waste container 15 serves as a temporary storage point, allowing for the centralized collection of small pieces of waste soil for subsequent unified processing. The structure of the waste soil transport chute 7 allows for continuous flow of waste soil within the chute, reducing manual intervention and improving transportation efficiency.

[0026] Optionally, the muck container 15 is designed to be detachable for easy replacement and cleaning. When the muck container 15 is full, it can be directly removed and transported out of the tunnel by the transport trolley 12, while an empty muck container 15 is replaced to continue collecting muck.

[0027] Optionally, the slag transport chute 7 is constructed by connecting multiple overlapping sections to form a telescopic structure. The chute can automatically adjust its length as needed, reducing the amount of adjustment work during construction.

[0028] In some embodiments, the tension shield 8 is provided with a support shoe 16, a support shoe cylinder 17, and a propulsion cylinder 18. The support shoe 16 is arranged on the side of the tension shield 8 to tension the tunnel side rock wall. The support shoe cylinder 17 is arranged along the radial direction of the tunnel. The propulsion cylinder 18 extends along the axial direction of the tunnel and is evenly arranged along the circumferential direction of the tension shield 8.

[0029] Specifically, the support shoe 16 is arranged on the side of the tensioning shield 8 to directly contact the tunnel side rock wall and provide stable lateral support. The support shoe 16 has a large contact area to distribute pressure and reduce local damage to the rock wall. The support shoe 16 can adapt to the unevenness of the tunnel side rock wall, ensuring good contact and stable support between the tensioning shield 8 and the rock wall. The support shoe cylinder 17 can precisely adjust the tensioning force according to construction needs and geological conditions. In cases of poor geological conditions or soft rock walls, the support shoe cylinder 17 can provide a greater tensioning force to ensure the stability of the tensioning shield 8. The propulsion cylinder 18 extends along the axial direction of the tunnel and is used to push the tensioning shield 8 and the segment assembly machine 9 on it forward. The extension and retraction of the propulsion cylinder 18 enables the step-like movement of the tensioning shield 8.

[0030] In some embodiments, the integrated excavation and assembly connecting passage construction system further includes a grouting pipe 19, which is arranged circumferentially on the side of the tensioning shield 8 away from the first lifting platform 5.

[0031] Specifically, grouting pipes 19 are used to complete the grouting process, filling the gap between the rear segment and the rock wall with gravel and mortar. Grouting pipes 19 are arranged around the circumference of the support shield 8 to ensure that the grout can evenly cover the entire circumference of the tunnel, effectively fill the gap between the segment and the tunnel rock wall, and improve the overall stability of the connecting passage. There are six grouting pipes 19 in total.

[0032] In some embodiments, the propulsion device further includes a tail shield 21, which is located on the side of the supporting shield 8 away from the first lifting platform 5, and a tail brush and a slurry stop plate are provided on the tail shield 21.

[0033] Specifically, the tail shield 21 is installed on the side of the tensioning shield 8 away from the first lifting platform 5, located at the rear end of the connecting passage. The tail shield 21 is fixed together with the tensioning shield 8 to ensure they work together during construction. The tail shield 21 protects the rear end of the connecting passage from interference and damage from external factors during excavation and assembly. A tail brush is installed at the rear end of the tail shield 21 to seal the rear opening of the connecting passage. The tail brush is typically made of flexible material, allowing it to fit tightly against the tunnel wall and prevent groundwater and debris from entering the connecting passage.

[0034] Grout stoppers are installed inside the tail shield 21 to prevent grout from flowing back into the connecting passage during grouting. The grout stoppers are typically made of high-strength, corrosion-resistant materials, capable of withstanding grouting pressure and ensuring the smooth progress of the grouting process. The grout stoppers also protect the tunnel segments from grout erosion. Through the isolation provided by the grout stoppers, the tunnel segments remain dry and clean during assembly and grouting, reducing damage caused by grout erosion.

[0035] In some embodiments, the integrated tunneling and splicing connecting passage construction system also includes a reaction frame 20, which is arranged at one end of the connecting passage adjacent to the main tunnel to resist the stress on the tunnel segments.

[0036] Specifically, the main function of the reaction frame 20 is to resist the reaction force generated during the segment assembly process. During segment assembly, the propulsion device applies a forward force to push the segments into place. The reaction frame 20 provides a stable reaction point through contact with the tunnel rock wall, preventing the equipment from shifting or deforming due to the reaction force.

[0037] Optionally, a pressure sensor can be installed at the contact point between the reaction frame 20 and the tunnel rock wall to monitor the pressure borne by the reaction frame 20 in real time.

[0038] In some embodiments, a drive device is provided at the bottom of the movable platform 2 to drive the movable platform 2 to move.

[0039] Specifically, the driving device can be a motor or a telescopic push rod, etc. The motor can drive the walking wheels at the bottom of the movable platform 2 to rotate through a belt, transmission chain, etc., thereby driving the movable platform 2 to move.

[0040] In some embodiments, the height adjustment device 4 includes a drive disk, a rack, a gear, and a movable seat. The rack is slidably connected to the movable seat, the gear meshes with the rack, the drive disk passes through the movable seat and is connected to the gear to drive the gear to rotate, the rack is connected to the water drill 1, and the movable seat is slidably connected to the rotating track 3.

[0041] Specifically, the drive disc is the power source for the height adjustment device 4, rotating to drive the gears. The drive disc can be driven by a motor for precise rotation control, and can also be manually rotated when necessary. The rotation of the gears enables the linear motion of the rack. The rack is slidably connected to the moving base, and its vertical movement adjusts the height of the water drill 1. The rotation of the drive disc drives the gears, which in turn cause the rack to move vertically. The rack's movement is transmitted to the water drill 1 through the moving base, thus achieving height adjustment. The meshing transmission of the gears and rack enables high-precision height adjustment, ensuring that the water drill 1 accurately reaches the target height.

[0042] In some embodiments, the rotary track 3 includes two parallel guide rails, the movable seat is slidably connected to the guide rails, and the guide rails are connected to the movable platform 2.

[0043] Specifically, the two parallel guide rails can share the pressure and vibration from the water drill 1 and the moving seat, reduce the impact of the vibration of the water drill 1 during drilling on the guide rails, extend the service life of the guide rails, and even if one side of the guide rail is damaged, the moving seat can still continue to move along the intact side of the guide rail.

[0044] In some embodiments, the height adjustment device 4 further includes a support member, the first end of which is slidably connected to the movable platform 2, and the second end of which is connected to the end of the water drill 1 away from the movable base.

[0045] Specifically, the support member can be a long rod or a long plate. The movable frame 2 has a through hole for the support member to pass through. The second end of the support member is connected to the water drill 1 to support the water drill 1 and ensure its balance. The support member is fixed to the movable frame 2 by pins, bolts, etc., to restrict the support member and thus perform its supporting function.
