Description

Technical Field

[0001] This utility model relates to the field of mountain tunnel construction technology, and in particular to a construction system for an integrated excavation and assembly connecting passage. Background Technology

[0002] In the field of tunnel construction technology, multiple connecting passages are typically designed and constructed between two adjacent tunnels to serve functions such as tunnel connection, drainage, fire protection, and emergency escape. Given the characteristics of mountain tunnels—long sections, numerous connecting passages, and hard rock geology—the demand for connecting passage construction is constantly increasing. Currently, connecting passage construction employs a combination of non-blasting excavation and segment assembly. However, the separate excavation and segment assembly steps result in low tunnel forming efficiency, require multiple pieces of equipment to operate in stages, and face difficulties in equipment coordination, leading to long construction cycles. Utility Model Content

[0018] 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.

[0019] 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 and a central rotary drive 2. Multiple water-cooled drills 1 are arranged on a first support. The central rotary drive 2 is driven and connected to the first support. A reaction rod 17 is arranged on the first support. The propulsion device includes a propulsion component 4, a support frame, a top support 12, and a lateral support. The lateral support is arranged on the main beam. The first end of the main beam is connected to the central rotary drive 2. The propulsion component 4 is arranged on the support frame to push the tunnel segments. The top support 12 is arranged on the main beam to support the tunnel. The material conveying device includes a tunnel segment assembler 5, a material hoist 16, a winch 15, and a boat-shaped plate 7. The tunnel segment assembler 5 is arranged at the second end of the main beam. The material hoist 16 is adjacent to the main tunnel. The winch 15 is arranged on the support of the main tunnel and is driven and connected to the boat-shaped plate 7. The boat-shaped plate 7 is arranged between the main beam and the material hoist 16.

[0020] The first end of the main beam is near the tunnel face, and the second end is near the main tunnel. The water-cooled drill 1, through the synergistic action of water flow and the drill bit, can quickly and smoothly drill holes in rock or soil layers. In this system, multiple water-cooled drills 1 are arranged on the first support, allowing for flexible adjustment of the drilling position and angle according to the cross-sectional shape and size requirements of the connecting passage, achieving omnidirectional drilling operations at the tunnel face. The central rotary drive 2 is connected to the first support transmission, driving the first support and the water-cooled drills 1 on it to rotate around the central axis. The rotation of the first support by the central rotary drive 2 causes the water-cooled drills 1 to move circumferentially relative to the tunnel, allowing them to cover a larger excavation area, reducing frequent equipment movement and adjustments, and improving excavation efficiency.

[0021] The reaction rod 17 is arranged on the first support and integrated with the water-jet drill 1 and the central rotary drive 2. When the segment assembler 5 advances the segment into place, the reaction rod 17 provides stable reaction support for the segment assembler 5, ensuring that the segment can be accurately and stably assembled into place. This ensures that the segment assembler 5 remains stable when advancing the segment, preventing equipment displacement or vibration caused by the reaction force, reducing assembly errors caused by equipment vibration or displacement during segment assembly, and further improving the construction quality of the connecting passage. Therefore, the stable support of the reaction rod 17 reduces the equipment adjustment time of the segment assembler 5 due to vibration or displacement during assembly, improving assembly efficiency. Furthermore, during tunneling, the water-jet drill 1 applies a forward drilling force to the rock and soil. The reaction rod 17 provides a stable reaction support point for the tunneling device to balance the drilling force, preventing displacement or vibration of the tunneling device due to the reaction force, enhancing the stability of the entire tunneling device, and ensuring the smooth progress of the tunneling process.

[0022] The support frame provides support and guidance for the propulsion component 4. The propulsion component 4 is arranged on the support frame. The propulsion component 4 can push the tunnel segments to provide thrust for the assembly of the tunnel segments by extending and retracting the hydraulic cylinder. The interaction between the hydraulic cylinder of the propulsion component 4 and the tunnel segments can drive the tunneling device and the propulsion device to move relative to the tunnel segments.

[0023] The top support 12 supports the soil and rock mass at the tunnel ceiling to prevent collapse. Located on the main beam, it protects the tunnel ceiling from falling rocks or other debris that could injure workers and equipment. Lateral supports, also on the main beam, support the soil and rock mass on the tunnel sidewalls, ensuring their stability. The material hoist 16, located near the main tunnel shaft, is used to hoist tunnel segments and other materials from the main tunnel shaft to the construction area. It enables large-scale hoisting operations, improving material transport efficiency. The winch 15 is mounted on the main tunnel shaft support and is connected to the boat-shaped plate 7 via a drive system. The boat-shaped plate 7, positioned between the main beam and the material hoist 16, carries and transports materials. The winch 15 uses a wire rope to pull the boat-shaped plate 7, moving it below the main beam to transport materials from the main tunnel shaft to the construction area, achieving continuous material conveying. The boat-shaped plate 7 can move flexibly below the main beam, transporting materials to the required location, working in conjunction with the winch 15 to achieve efficient material transport.

[0024] The integrated tunnel construction system according to embodiments of the present invention has the advantages of easy installation inside the tunnel and high construction efficiency.

[0025] In some embodiments, the lateral support includes a front lateral support 9 and a rear lateral support 13, which are connected to the first end and the second end of the main beam, respectively.

[0026] In some embodiments, the front lateral support 9 is slidably connected to the main beam, and the rear lateral support 13 is fixedly connected to the main beam.

[0027] Specifically, dividing the lateral support into front lateral support 9 and rear lateral support 13 can provide more balanced support and adapt to the tunnel shape. The front lateral support 9 is arranged at the first end of the main beam, that is, the end closest to the tunnel face. During the excavation process, the front lateral support 9 is mainly used to support the rock and soil of the tunnel sidewall to prevent the sidewall from collapsing. At the same time, it provides stable lateral support for the excavation equipment, ensuring the smooth progress of the excavation process. Supporting the rock wall can stabilize the front end of the equipment and can also adjust the distance of the front end of the equipment relative to the two sides of the tunnel, providing anti-torsional torque.

[0028] The rear lateral support 13 is connected to the second end of the main beam, which is closer to the main tunnel end. The rear lateral support 13 is mainly used to support the tunnel sidewalls and segments in the constructed area, ensuring the stability of the assembled segments. It also provides stable lateral support for the propulsion device, preventing lateral displacement of the equipment during construction. The rear lateral support 13 can adjust the distance between the rear end of the equipment and the sides of the tunnel, providing anti-torsional torque. Both the front lateral support 9 and the rear lateral support 13 include a telescopic hydraulic cylinder.

[0029] In some embodiments, a main beam telescopic sleeve 18 is also included. The main beam telescopic sleeve 18 is arranged on the main beam and connected to the segment assembly machine 5 to drive the segment assembly machine 5 to move along the main beam.

[0030] Specifically, the main beam telescopic sleeve 18 can drive the segment assembly machine 5 to move along the main beam, realizing the forward and backward movement function of the segment assembly machine 5. The main beam telescopic sleeve 18 includes a first section and a second section. The first section is connected to the main beam, and the second section is connected to the segment assembly machine 5. The first section partially enters the second end. During the segment assembly process, the main beam telescopic sleeve 18 can push the segment assembly machine 5 to the assembly position. After the assembly is completed, the main beam telescopic sleeve 18 pulls the segment assembly machine 5 back to the initial position through tension, preparing for the next assembly operation. The main beam telescopic sleeve 18 drives the segment assembly machine 5 to move along the main beam, which can accurately position the segment assembly machine 5 to the assembly position, ensuring that the segments can be accurately assembled, reducing the assembly error caused by inaccurate positioning, and enabling the movement and assembly operation of the segment assembly machine 5 to be carried out in an integrated manner, reducing the coordination workload between equipment and improving the continuity of the construction process.

[0031] In some embodiments, the propulsion device is provided with a front support 3 and a rear support 6, which are arranged on the main beam to support the first end and the second end of the main beam, respectively.

[0032] Specifically, the front support 3 is located at the first end of the main beam (close to the working face) and is mainly used to support the front end of the equipment. The horizontal height of the equipment is adjusted by hydraulic cylinders to ensure that the equipment maintains a stable posture during tunneling. The front support 3, through hydraulic cylinder adjustment, ensures the stability of the tunneling device and the front end of the main beam, preventing tilting due to changes in geological conditions or the equipment's own weight.

[0033] The rear support 6 is located at the second end of the main beam (closest to the main tunnel end) and is mainly used to support the rear end of the equipment. The rear support 6 not only provides stable support but also assists in the movement of the equipment, ensuring smooth movement during construction. The rear support 6 uses a combination of hydraulic cylinders and rollers. The hydraulic cylinders support the second end of the main beam, while the rollers contact and slide against the tunnel segments to assist in movement, facilitating the movement of the propulsion device.

[0034] The combined action of the front support 3 and the rear support 6 effectively prevents the equipment from tilting or overturning during tunneling. By adjusting the horizontal height of the equipment with hydraulic cylinders, the front support 3 ensures the stability of the front end of the equipment; while the rear support 6 provides stable support for the rear end of the equipment, enhancing its safety and allowing the equipment to flexibly adjust its posture according to changes in the construction environment.

[0035] In some embodiments, a radial moving device 14 is also included. The radial moving device 14 is connected to the water drill 1 to drive the water drill 1 to move along the radial direction of the tunnel. The radial moving device 14 includes a rack and a drive motor. The drive motor meshes with the rack through a gear, and the two drive motors are arranged at both ends of the rack.

[0036] Specifically, the radial movement device 14 is connected to the water-cooled drill 1 and is used to move the water-cooled drill 1 along the radial direction of the tunnel. This movement function allows the water-cooled drill 1 to adjust the drilling position according to the tunneling needs, better adapting to the tunnel geometry and construction requirements. When it is necessary to adjust the radial position of the water-cooled drill 1, the drive motor drives the rack and pinion through gears, moving the water-cooled drill 1 to the designated position along the radial direction of the tunnel. This design allows the water-cooled drill 1 to flexibly adjust the drilling position during tunneling, improving the flexibility and efficiency of tunneling. Under complex geological conditions, the soil and rock mass of the tunnel may have heterogeneity or local weak areas. The radial movement device 14 allows the water-cooled drill 1 to flexibly adjust the drilling position according to changes in geological conditions, avoiding tunneling difficulties or equipment damage caused by improper drilling position. Two drive motors are symmetrically arranged at both ends of the rack and pinion; this symmetrical design ensures the smooth movement of the water-cooled drill 1. The cooperation of the rack and pinion enables precise adjustment of the drilling position.

[0037] In some embodiments, the propulsion member 4 includes a telescopic cylinder and a propulsion cylinder, wherein the telescopic cylinder is used to drive retraction and the propulsion cylinder is used to push.

[0038] Specifically, the propulsion component 4 provides reaction force for segment assembly through the cooperation of the telescopic hydraulic cylinder and the propulsion hydraulic cylinder. The telescopic hydraulic cylinder of the propulsion component 4, in conjunction with the reaction rod 17, can complete the segment assembly. The propulsion hydraulic cylinder is used to push forward. When the propulsion device and the tunneling device need to move forward, the propulsion hydraulic cylinder can drive the propulsion device and the tunneling device to move towards the tunnel face. When the tunneling device needs to retract towards the main tunnel, the telescopic hydraulic cylinder can drive the tunneling device to move by pushing the reaction rod 17.

[0039] In some embodiments, the top support 12 includes a support plate and support cylinders. The support plate extends along the extension direction of the main beam and abuts against the top plate of the tunnel. One end of the plurality of support cylinders is connected to the support plate, and the other end of the plurality of support cylinders is connected to the main beam.

[0040] Specifically, the main function of the support plate is to prevent damage to construction personnel and equipment caused by falling debris during the tunneling process. The support plate acts as temporary roof support, providing a relatively stable roof environment for tunneling operations and preventing the collapse of the tunnel roof rock and soil. Support cylinders are used to support the support plate; adjusting the height of the support cylinders changes the position of the support plate, thereby adjusting the strength of the support at the tunnel roof.

[0041] Example 1: The tunneling device includes a water-cooled drill 1, a radial moving device 14, and a central rotary drive 2. Multiple water-cooled drills 1 are arranged on a first support. The central rotary drive 2 drives the first support to rotate. A reaction rod 17 is arranged on the first support to provide reaction force. A top support 12 is arranged on the main beam to support the area above the first to second ends of the main beam. Front supports 3 and rear supports 6 are symmetrically arranged, and both front supports 3 and rear supports 6 are supported by hydraulic cylinders. This shortens the distance of the main beam, eliminates the need for a segment crane, and allows the ship-shaped plate 7 to directly transport the segments to below the segment assembly machine 5.

[0042] During tunnel excavation, the structural height of the equipment is adjusted using front support 3 and rear support 6. Front lateral support 9 and rear lateral support 13 provide lateral support for the front and rear sections of the equipment, respectively. The distance between the equipment and the tunnel wall is adjusted to ensure the equipment's position. Top support 12 extends to tighten the top rock layer of the tunnel. Central rotary drive 2 adjusts the excavation position of the tunneling device in the circumferential direction of the tunnel. Radial movement device 14 adjusts the radial position of water-jet drill 1 in the tunnel, and water-jet drill 1 begins operation.

[0043] During the muck removal process, the front lateral support 9 is retracted and moves towards the second end of the main beam. Then, the front lateral support 9 extends and presses against the lateral rock wall of the tunnel. The rear lateral support 13 retracts, the main beam telescopic sleeve 18 extends, and after the rear lateral support 13 extends to the top of the rock wall, the support cylinder of the top support 12 retracts. The main beam telescopic sleeve 18 retracts, driving the entire equipment backward, leaving 800mm of space in front. A rock splitting rod is then installed to split the rock face. The winch 15 drags the rocks to the main tunnel for muck removal, and the material crane 16 transfers the muck.

[0044] During assembly, the rear lateral support 13 retracts, the top support 12 retracts, the pusher 4 pushes the tunnel segments, and the entire equipment is moved to create space for tunnel segment assembly. The front lateral support 9 moves to the first end of the main beam. The front lateral support 9, rear lateral support 13, front support 3, and rear support 6 adjust the horizontal and lateral spacing of the equipment relative to the tunnel. The rear lateral support 13 retracts, the top support 12 extends, and the main beam telescopic sleeve 18 provides axial movement for the tunnel segment assembly machine 5. The tunnel segment assembly machine 5 grabs and assembles the tunnel segments, and the previous ring of tunnel segments is rounded using the tunnel segment adjusting bolts. The material hoist 16 lifts the tunnel segments onto the ship-shaped plate 7, and the winch 15 moves the ship-shaped plate 7 to the tunnel segment assembly machine 5.
