Abstract
Description
Technical Field
[0001] This utility model relates to the field of mountain tunnel construction technology, and in particular to a segment assembly construction system for connecting passages. 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

To this end, embodiments of this utility model propose a segment assembly and construction system for a connecting tunnel, which has the advantages of easy installation inside the tunnel and high construction efficiency.
[0004] According to an embodiment of the present invention, the connecting tunnel segment assembly construction system includes a tunneling device, a propulsion device, and a material conveying device. The tunneling device includes a water-cooled drill and a central rotary drive. Multiple water-cooled drills are arranged on a first support. The central rotary drive is drivenly connected to the first support. The propulsion device includes a propulsion component, a support frame, a segmented shell, and a lateral support. The lateral support is arranged on a main beam. The first end of the main beam is connected to the central rotary drive.

[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 connecting passage segment assembly 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 connected to the first support in a transmission manner. The propulsion device includes a propulsion component 3, a support frame, a segmented shell 13, and a lateral support 6. The lateral support 6 is arranged on a main beam. The first end of the main beam is connected to the central rotary drive 2. The propulsion component 3 is arranged on the support frame to push the segments. The segmented shell 13 abuts against the inner wall of the tunnel and is connected to the main beam. The material conveying device includes a segment assembly machine 4, a material hoist 10, a winch 9, and a boat-shaped plate 5. The segment assembly machine 4 is connected to the second end of the main beam. The material hoist 10 is adjacent to the main tunnel. The winch 9 is arranged on the support of the main tunnel and is connected to the boat-shaped plate 5 in a transmission manner. The boat-shaped plate 5 is arranged between the main beam and the material hoist 10.
[0021] In this system, multiple water-cooled drills 1 are arranged on the first support. The drilling position and angle can be flexibly adjusted according to the cross-sectional shape and size requirements of the connecting passage, enabling omnidirectional drilling operations at the tunnel face. The central rotary drive 2 is connected to the first support and drives 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 relative to the circumference of the tunnel, allowing them to cover a larger excavation area, reducing frequent equipment movement and adjustments, and improving excavation efficiency. The support frame provides support and guidance for the propulsion component 3, which is arranged on the support frame. The propulsion component 3, through the extension and retraction of hydraulic cylinders, can push the tunnel segments, providing thrust for segment assembly. The interaction between the hydraulic cylinders of the propulsion component 3 and the tunnel segments can drive the excavation device and the propulsion device to move relative to the tunnel segments. The segmented shell 13 supports the rock and soil at the top of the tunnel, preventing its collapse. The segmented shell is arranged around the main beam and protects the tunnel top, preventing falling rocks or other debris from injuring construction personnel and equipment. The segmented shell 13 provides support and protection to the rock wall by clamping it against the rock. Lateral supports 6 are arranged on the main beam to support the rock and soil of the tunnel sidewalls, ensuring their stability. A material hoist 10, located near the main tunnel, is used to hoist segments, materials, etc., from the main tunnel to the construction area. It enables large-scale hoisting operations, improving material transport efficiency. A winch 9 is mounted on the support of the main tunnel and is connected to the hull-shaped plate 5 via a drive system. The hull-shaped plate 5 is positioned between the main beam and the material hoist 10 to carry and transport materials. The winch 9 pulls the hull-shaped plate 5 under the main beam via a wire rope, transporting materials from the main tunnel to the construction area, achieving continuous material conveying. The hull-shaped plate 5 can move flexibly under the main beam, transporting materials to the required location, working in conjunction with the winch 9 to achieve efficient material conveying.
[0022] In some embodiments, the lateral support 6 is slidably connected to the first end of the main beam.
[0023] Specifically, the lateral support 6 is arranged at the first end of the main beam, i.e., the end closest to the tunnel face. During excavation, the lateral support 6 is mainly used to support the rock and soil of the tunnel sidewalls to prevent sidewall collapse. 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 adjust the distance between the front end of the equipment and the sides of the tunnel, providing anti-torsional torque. The lateral support 6 can slide relative to the main beam, making it easy to change the support position of the lateral support 6 on the main beam. The lateral support 6 and the segmented shell 13 provide step-by-step support to the rock wall, which can maintain support while allowing the overall equipment to move step by step.
[0024] In some embodiments, the tunneling device further includes a reaction rod 11, which is arranged on the first support.
[0025] Specifically, the reaction rod 11 is arranged on the first support and integrated with the water-cooled drill 1 and the central rotary drive 2. When the segment assembly machine 4 pushes the segment into place, the reaction rod 11 can provide stable reaction support for the assembly machine, ensuring that the segment can be accurately and stably assembled into place. This ensures that the segment assembly machine 4 can remain stable when pushing 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. Thus, the stable support of the reaction rod 11 can reduce the equipment adjustment time of the segment assembly machine 4 due to vibration or displacement during the assembly process, and improve assembly efficiency.
[0026] In addition, during the tunneling process, the water-powered drill 1 applies a forward drilling force to the rock and soil, and the reaction rod 11 provides a stable reaction support point for the tunneling device to balance the drilling force, prevent the tunneling device from being displaced or vibrating due to the reaction force, enhance the stability of the entire tunneling device, and ensure the smooth progress of the tunneling process.
[0027] In some embodiments, the connecting channel segment assembly construction system further includes a main beam telescopic sleeve 12, which is arranged on the main beam and connected to the segment assembly machine 4 to drive the segment assembly machine 4 to move along the main beam.
[0028] Specifically, the main beam telescopic sleeve 12 can drive the segment assembly machine 4 to move along the main beam, realizing the forward and backward movement function of the segment assembly machine 4. The main beam telescopic sleeve 12 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 4. The first section partially enters the second end. During the segment assembly process, the main beam telescopic sleeve 12 can push the segment assembly machine 4 to the assembly position. After the assembly is completed, the main beam telescopic sleeve 12 pulls the segment assembly machine 4 back to the initial position through tension, preparing for the next assembly operation. The main beam telescopic sleeve 12 drives the segment assembly machine 4 to move along the main beam, which can accurately position the segment assembly machine 4 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 4 to be carried out in an integrated manner, reducing the coordination workload between equipment and improving the continuity of the construction process.
[0029] In some embodiments, the segmented housing 13 is connected to an adjacent segmented housing 13 via a hinge seat 14, and the segmented housing 13 is connected to the main beam via a telescopic hydraulic cylinder.
[0030] Specifically, during tunnel construction, the shape of the rock wall may not be perfectly regular, and there may be some undulations and unevenness. The segmented shell 13 connected by the hinged seat 14 can be adjusted according to the actual shape of the rock wall. The segmented shell 13 is connected to adjacent segmented shells 13 through the hinged seat 14, which allows the two segmented shells 13 to rotate relative to each other, better adapting to the shape changes of the tunnel rock wall, so as to better fit against the rock wall. The segmented shell 13 is connected to the main beam or other parts of the equipment through a telescopic cylinder to provide support for itself. The telescopic cylinder realizes the relative telescopic movement between the segmented shell 13 and the main beam. The telescopic cylinder can adjust the position of the segmented shell 13 according to construction needs. For example, during tunnel excavation, when it is necessary to adjust the fit between the segmented shell 13 and the rock wall, the telescopic cylinder can extend and retract, making the segmented shell 13 move closer to or away from the rock wall. At the same time, the telescopic cylinder also plays a supporting role, which can bear the weight of the segmented shell 13 and various forces generated during construction, ensuring the stability and safety of the segmented shell 13. The segmented shell 13 forms a rotatable connection through the hinge seat 14, which helps to adapt to complex rock wall shapes and cope with different tunnel end faces, ensuring that the segmented shell 13 fits tightly with the rock wall for stable support.
[0031] In some embodiments, the plurality of segmented shells 13 are divided into two groups and evenly distributed along the circumferential direction of the tunnel, with the two groups of segmented shells 13 arranged on both sides of the main beam.
[0032] Specifically, the multiple segmented shells 13 are divided into two groups. This grouping method is to better adapt to the circumferential structure of the tunnel. The segmented shells 13 are evenly arranged at certain intervals around the circumference of the tunnel. This even distribution of the two groups of segmented shells 13 ensures that the segmented shells 13 are subjected to uniform stress in the circumferential direction of the tunnel, avoiding structural deformation or damage caused by uneven stress. The two groups of segmented shells 13 are arranged on both sides of the main beam, forming a stable support structure between the segmented shells 13 and the main beam, similar to the structure of bridge piers supporting the bridge deck. This effectively disperses the pressure of the tunnel rock walls on the segmented shells 13, and also facilitates the connection and force transmission between the segmented shells 13 and the main beam.
[0033] In some embodiments, a slide rail 7 is provided on the top of the main beam, and the segment assembly machine 4 is slidably connected to the slide rail 7.
[0034] Specifically, the segment assembly machine 4 can flexibly adjust its position by moving along the slide rail 7 on the main beam, facilitating segment assembly operations and reducing the time spent transferring equipment between different locations. The design of the slide rail 7 allows the segment assembly machine 4 to maintain precise alignment during movement, and the guiding effect of the slide rail 7 reduces positional deviation of the segment assembly machine 4 during movement.
[0035] In some embodiments, the propulsion member 3 includes a reaction cylinder and a propulsion cylinder, the reaction cylinder being connected to the reaction rod 11, and the propulsion cylinder being used to push the tube segment.
[0036] Specifically, the propulsion component 3 provides reaction force for segment assembly through the cooperation of a reaction cylinder and a propulsion cylinder. The reaction cylinder of the propulsion component 3, in conjunction with the reaction rod 11, completes the segment assembly. The propulsion cylinder is used to push forward. When the propulsion device and the tunneling device need to advance, the propulsion cylinder can drive the propulsion device and the tunneling device to move towards the tunnel face. When the tunneling device needs to exert reaction force towards the main tunnel, the reaction cylinder can drive the tunneling device to move. The reaction cylinder is connected to the reaction rod 11, and the other end of the reaction rod 11 is fixedly connected to the tunnel face. The extension of the reaction cylinder can push the entire equipment backward.
[0037] In some embodiments, a radial moving device 8 is also included. The radial moving device 8 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 8 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.
[0038] Specifically, the radial movement device 8 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 8 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.
