Abstract
Description
Technical Field
[0001] This invention relates to the field of building construction technology, and in particular to a single-layer folded plate arch concrete construction process and apparatus. Background Technology
[0002] With the increasing maturity of construction technology, the number of tunnels being built is also increasing. After the main structure of the tunnel is completed, a waterproof layer is laid and a lining is installed to form an arched perforated plate structure, which supports the tunnel and enhances the support strength of the main tunnel structure.
[0003] Currently, in order to improve overall construction efficiency, precast concrete lining is gradually being widely used. This involves dividing an arched tunnel in the same cross-section into multiple lining sections, transporting them into the tunnel, and then assembling and installing them to complete the overall support structure. However, due to space limitations within the tunnel, forklifts or small hoisting equipment are typically used to transport the linings to the designated location. After transporting them, a support platform is erected to install each lining module one by one. Moreover, experienced construction personnel are required to position and fix the linings during installation. The process is complex and difficult. Furthermore, the installation of each lining module requires that the current lining module be installed and fixed before the next lining module can be transported and assembled to avoid congestion within the tunnel, which could lead to accidents and limit overall construction efficiency.

Detailed Implementation
[0047] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and the accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.
[0048] Specific implementation method one: Combining Figure 1-18As shown, a single-layer folded plate arch concrete construction device is characterized by comprising: a walking frame 1, with multiple supporting rollers 101 arranged above the walking frame 1 along its length. The supporting rollers 101 are connected on both sides by an L-shaped rod structure, which can effectively limit and protect them. A drive assembly 2 for pressing and pushing the lining displacement is provided in the middle of the two sets of supporting rollers 101. One end of the walking frame 1 is the feeding direction, and the other end is the discharging direction. The feeding direction of the walking frame 1 is provided with a receiving adjustment component 3, and the discharging direction is provided with a circumferential placement assembly 4 for arranging the lining in the circumferential direction. A multi-axis adjustment device 5 is installed at the bottom of the circumferential placement assembly 4, which can adjust the circumferential placement assembly 4 in the x and z directions, thereby facilitating docking and placement with the lining; a docking component 6, with a mating hole 601 in the middle. The two sides of the docking component 6 are respectively connected to the lining, and the mating hole 601 is connected to the circumferential placement assembly; the lining module is placed and transported through the receiving adjustment component 3. At the end of the drive assembly 2, the lining is conveyed by the drive assembly 2 and moved along the support roller 101 to the top of the circumferential placement assembly 4 and stops. Then, the circumferential placement component 4 is driven by the multi-axis adjustment device 5 to adjust its own position and connect and fix it with the mating hole 601 of the docking part 6 on the lining. Subsequently, the drive assembly 2 moves together with the multi-axis adjustment device 5, slides out of the walking frame 1 and stops at the designated position. Then, the circumferential placement component 4 adjusts the position of the lining by telescoping and rotating to complete the positioning. At this time, the circumferential placement assembly 4 can realize the separation of its own part structure, thereby installing new connection parts and connecting with the subsequent docking part 6, which effectively improves the work efficiency. At the same time, the whole adopts top feeding, and construction work and personnel movement can be carried out below, making full use of the internal construction space of the tunnel. Moreover, the use of mechanized transportation and placement reduces the requirements for the work experience of construction personnel, and the operation process is also effectively optimized, ensuring the overall construction progress and reducing construction costs.
[0049] Combination Figure 1 and Figure 2 As shown, motors are installed on the support rollers 101 at both ends, so that when the lining reaches the two ends of the drive assembly 2, it is convenient to carry out feeding and discharging of the lining. Instead of relying solely on the drive assembly 2 to drive the lining displacement, the coordinated operation can effectively avoid lining deviation. Moreover, the use of support rollers 101 to support the lining reduces friction during transportation and protects the integrity of the lining.
[0050] Combination Figure 3-7As shown, the drive assembly 2 includes a fixed plate 201, a support plate 202, and a conveyor belt 203. The fixed plate 201 is welded or mounted on the traveling frame 1 using screws, bolts, etc., and a first hydraulic cylinder 204 is arranged on one side. The support plate 202 has rotatably connected rollers 205 on its upper and lower sides, and its rotation is controlled by a motor arranged in the middle. The sides of the support plate 202 are connected to the fixed plate 201 and the first hydraulic cylinder 204, respectively. The conveyor belt 203 is sleeved on the rollers 205. By controlling the up and down displacement of the first hydraulic cylinders 204 at both ends of the traveling frame 1, the lining can be loosened or tightened, making it more convenient to use. When the conveyor belt 203 descends and comes into contact with the lining, the friction between the two drives the conveyor belt 203 to rotate along the support roller 101, completing the transportation of the lining along the support roller 101. The flexibility of the conveyor belt 203 allows it to adapt to the arc surface of the lining after contact, increasing the contact area and providing stability. The roller 205 and the motor are connected by a belt, while the conveyor belt 203 is made of rubber to prevent damage to the surface of the lining module. In addition, the length of the conveyor belt 203 extends beyond the outermost support roller 101 by a certain distance, which facilitates feeding or discharging.
[0051] Other adjustment and conveying modes of the drive component 2 are as follows: the two ends of the walking frame 1 are respectively equipped with first hydraulic cylinders 204. At the same time, by utilizing the flexibility of the conveyor belt 203 itself, the height of the two ends of the conveyor belt 203 can be adjusted to meet the usage requirements of different situations. For example, when there are linings waiting to be used on the support roller 101, and it is necessary to convey the linings behind, the height of the end that does not need to be transported can be raised, so that the conveyor belt 203 is tilted. In this way, it not only meets the needs of conveying the linings at the adjustment component 3, but also does not affect the connection of the linings at the circumferential placement component 4, and at the same time realizes that multiple lining modules are arranged sequentially on the support roller 101.
[0052] In a preferred embodiment, a plurality of contact elements 206 are symmetrically arranged along the movement direction of the conveyor belt 203, with 3-5 elements per group, preferably 3 elements. The multiple contact elements 206 are arranged at intervals and their heights increase sequentially, which facilitates contact with the lining surface and can assist in the positioning of the lining on the support rollers 101, thereby improving the stability of the lining during transportation. The cross-section of the contact element 206 can be semi-circular or trapezoidal, preferably semi-circular, to facilitate processing and production.
[0053] Combination Figure 2 , Figure 3 and Figure 8As shown, the receiving and adjusting component 3 includes a first track 301, a horizontal plate 302, and a lifting component 303. The first track 301 is welded or screwed to both sides of the traveling frame 1, and a second hydraulic cylinder 304 is provided at the end. The two sides of the horizontal plate 302 are slidably connected to the first track 301, and the end is screwed to the second hydraulic cylinder 304. A vertically arranged third hydraulic cylinder 305 is installed in the middle of the horizontal plate 302. The lifting component 303 is screwed to the third hydraulic cylinder 305, and the lifting component 303 has a "Y" shaped structure. The horizontal plate 302 is moved horizontally by the second hydraulic cylinder 304, and the height of the lining is adjusted by the third hydraulic cylinder 305, so that the lining can be accurately transported into the drive assembly 2 after it is placed.
[0054] When placing the lining, specifically, the second hydraulic cylinder 304 pushes the horizontal plate 302 to slide out of the interior of the traveling frame 1, so as to facilitate the placement of the hoisted lining on the lifting member 303 and avoid interference with the traveling frame 1. The lifting member 303 adopts a "Y" shaped structure, which improves the reliability after placement after contacting the lining, and at the same time, it will not interfere with the docking member 6 during placement.
[0055] In a preferred embodiment, the lifting member 303 is fixed in the middle by an adjustable frame 306 with double nuts, and a power drive wheel 307 is arranged in the middle of the adjustable frame 306. The power drive wheel 307 is controlled by a motor and has an elastic layer 308 on its surface. When the lining is hoisted and placed, it is not easy to align it in the suspended state. After the lining is placed, the power drive wheel 307 is rotated directly to drive the lining to make a fine adjustment on the lifting member 303, which improves the accuracy of the lining position after placement, speeds up the hoisting construction process, and improves work efficiency. At the same time, the mechanical adjustment provides higher adjustment accuracy. The design of the elastic layer 308 increases the friction after contact with the lining and reduces the requirements for installation accuracy.
[0056] Due to the variation in lining dimensions, the height of the lining after contact with the lifting component 303 may change. To address this, the position of the double nuts on the adjustable frame 306 is adjusted to change the height of the apex of the power drive wheel 307 relative to the horizontal plate 302, thus adapting to the changing curvature of the lining.
[0057] Combination Figure 9As shown in Figure 18, the multi-axis adjustment device 5 includes a second track 501 and a support rail 502; a fourth hydraulic cylinder 503 connected to the traveling frame 1 is provided below the second track 501, and a fifth hydraulic cylinder 504 connected to the support rail 502 is provided at one end; the support rail 502 is installed inside the second track 501 and is slidably connected; the fourth hydraulic cylinder 503 pushes the second track 501 to move up and down, thereby adjusting the overall height, while the fifth hydraulic cylinder 504 adjusts the horizontal position of the circumferential mounting part 4, thereby adjusting the x and z directions; wherein, the fourth hydraulic cylinder 503 is installed at both ends of the second track 501 to ensure the stability during height adjustment, and the arrangement of the two hydraulic cylinders increases the support force for the upper structure;
[0058] In a preferred embodiment, the circumferential mounting assembly 4 includes a frame 7, a vertical plate 8, and a telescopic rod 9. The frame 7 has two semicircular tracks 701 with different diameters arranged at its center. The interior of each semicircular track 701 is divided into multiple braking zones and equipped with a positioning brake 702. A sixth hydraulic cylinder 703 is mounted on the frame 7. The vertical plate 8 is connected to both the frame 7 and the sixth hydraulic cylinder 703, and a control motor 801 is located at its center. The telescopic rod 9 is slidably connected to the semicircular tracks 701, with an angle control component 901 at one end and the other end connected to the control motor 801. The control motor 801 controls the angle adjustment of the telescopic rod 9, while the semicircular tracks 701, in conjunction with the brake 702, complete the positioning of the telescopic rod 9 after the angle adjustment. The control motor 801 can also be connected to… The bottom end of the telescopic rod 9 detaches and is docked and fixed with a new telescopic rod 9, thus proceeding to the assembly work after the next lining connection. Under the drive of the sixth hydraulic cylinder 703, the plate frame 7 is kept as a whole fixed, the upright plate 8 slides, and the docking position of the control motor 801 is adjusted to achieve separate operations within the same structure, greatly improving the overall work efficiency. Among them, the braking area division of the semicircular track 701 should be adapted to the number of telescopic rods 9 that need to be positioned within the semicircular track 701. It is preferred to select 5 areas, and the lining is also divided into 5 parts for prefabrication. At the same time, the semicircular track 701 is also provided with a notch for the telescopic rod 9 to enter. The position of the notch should be between 78 and 85 degrees to avoid affecting the positioning of the subsequent telescopic rod 9 within the semicircular track 701.
[0059] The corner control component 901 includes a hydraulic cylinder motor connected to the end of the telescopic rod 9 and a rotatable frame connected to the hydraulic motor. Two sets of motor-controlled connecting heads are arranged on the top of the rotating frame. The distance between the connecting heads is equal to the distance between the two mating holes 601 of the mating component 6. The connecting heads are divided into multiple layers and symmetrically provided with rectangular openings. The mating holes 601 have multiple corresponding rectangular plates. After passing through the rectangular opening of the connecting head and the rectangular plate, the connecting head is electrically driven to rotate 90 degrees to complete the connection and fixation with the mating hole 601. Furthermore, the angle during lining assembly can be further adjusted by relying on the hydraulic motor to drive the rotating frame.
[0060] In a preferred embodiment, the control motor 801 has a retractable slide column 802 on its rotating shaft. The slide column 802 is sleeved with the end of the telescopic rod 9, and the end of the telescopic rod 9 has a hole for sleeved with the slide column 802. By controlling the extension or retraction of the slide column 802, the connection or release with the end of the telescopic rod 9 is completed. The slide column 802 can be driven by a hydraulic cylinder or an electric push rod.
[0061] In a preferred embodiment, the braking component 702 includes a pressure plate 704 slidably connected to the semicircular track 701, and an elastic element 705 for resetting the pressure plate 704. Hydraulic oil is injected into the semicircular track 701 through the inlet, pushing the pressure plate 704 to overcome the elastic force of the elastic element 705 and lock the sliding connection between the telescopic rod 9 and the semicircular track 701, thereby achieving the adjusted positioning of the telescopic rod 9. After the hydraulic oil is discharged, the elastic force of the elastic element 705 pushes the pressure plate 704 to reset, releasing the restriction on the telescopic rod 9. At the same time, each braking area is provided with a corresponding inlet, thereby controlling the braking function of each area. The elastic element 705 can be a spring or an arc-shaped spring plate.
[0062] Combination Figure 14 As shown, in order to ensure the sealing at the pressure plate 704, a sealing structure for the pressure plate 704 is also provided. Specifically, two sets of sealing rings are provided at the contact point between the pressure plate 704 and the side wall of the semi-circular track 701, and a metal oil sealing ring is arranged between the two sets of sealing rings. At the same time, a sheet-like sealing ring is arranged at the gap between the elastic element 705 and the semi-circular track 701 to further enhance the sealing effect and prevent leakage.
[0063] This invention also provides a single-layer folded plate arch concrete construction process, characterized by comprising:
[0064] S1. Tunnel excavation is completed and the tunnel is formed; then the traveling frame 1 is pushed into the tunnel.
[0065] S2. The prefabricated lining is hoisted above the receiving and adjusting component 3, aligned by the receiving and adjusting component 3, and transported to the feeding end of the drive assembly 2.
[0066] S3. The drive assembly 2 presses the upper surface of the lining, and in conjunction with the support rollers 101, guides the lining onto the row of support rollers 101, and transports the lining to the top of the circumferential placement assembly 4, ready for use.
[0067] S4. The circumferential mounting component 4 is fixedly connected to the docking part 6 on the lining. The multi-axis adjustment device 5 drives the circumferential mounting component 4 to move with the lining and slide out of the traveling frame 1. Then, the circumference and distance of the lining are adjusted to a suitable position for installation in the tunnel.
[0068] S5. Repeat steps S2-S4 above to complete the lining splicing and installation at the same cross section in sequence, and then proceed to the next stage of assembly.
[0069] This invention can also be applied to the repair of tunnel linings after tunnel construction is completed, specifically by replacing the linings at designated locations using the above-described process.
[0070] Combination Figure 1-18 As shown, the specific operation is as follows:
[0071] After the main tunnel structure is completed, the traveling frame 1 is driven to the location where the lining needs to be laid via the track laid on the tunnel surface. With the help of small hoisting equipment, it is placed at the feeding end of the traveling frame 1. During operation, the receiving and adjusting component 3 is activated, and the second hydraulic cylinder 304 pushes the horizontal plate 302 out. It stops after reaching the appropriate position to avoid interference with the traveling frame 1 during hoisting. Then, the lining with the connecting component 6 is hoisted above the lifting component 303 and lowered. When the lining is offset at the lifting component 303, the power drive wheel 307 is activated to adjust the lining. Then, the second hydraulic cylinder 304 is reset and drives the lining into the traveling frame 1. At this time, the third hydraulic cylinder 305 works to adjust the lining to the appropriate height (the third hydraulic cylinder 305 can also be adjusted in height during lining hoisting) and reaches the end of the drive component 2.
[0072] The first hydraulic cylinder 204 is activated, which drives the conveyor belt 203 to move downward and contact the lining located on the lifting member 303. Then the roller 205 drives the conveyor belt 203 to rotate, and the lining is driven to move along the support roller 101 by friction. The conveyor belt 203 and the contact member 206 are fully in contact with the lining. During transportation, the lining is prevented from tilting. When it reaches above the circumferential placement member 4, it stops and waits for use.
[0073] Start the circumferential mounting component 4 and the multi-axis adjustment device 5. Use the fourth hydraulic cylinder 503 and the fifth hydraulic cylinder 504 to adjust the horizontal direction and height of the telescopic rod 9 relative to the docking part 6. The angle of the telescopic rod 9 can be adjusted in conjunction with the control motor 801. Then, the telescopic rod 9 unfolds so that the connector enters the mating hole 601 and rotates 90 degrees to complete the connection and fixation with the docking part 6. Then drive the component 2 and the support rail 502 to move outward of the walking frame 1 at the same time. After reaching the designated position, the fifth hydraulic cylinder 504 stops.
[0074] The control motor 801 drives the telescopic rod 9 to rotate within the semi-circular track 701, adjusting the installation angle of the lining. The telescopic rod 9 then uses its multi-stage telescopic movement to push the lining to the appropriate position and stop. The brake 702 in the current area then locks and fixes the telescopic rod 9, and disengages the sliding column 802 from the end of the telescopic rod 9. At this point, the worker can begin installation. The sixth hydraulic cylinder 703 is activated to reset the upright plate 8. Simultaneously, a new telescopic rod 9 is hoisted and connected to the sliding column 802 on the control motor 801 for use in connecting the next lining. This eliminates the need to wait for the current lining to be installed before assembling the next lining, effectively improving work efficiency.
[0075] For the assembly of the lining, the method of first the two sides and then the middle is adopted. That is, after the lining module is divided into five pieces, namely A, B, C, D and E, the two sides AB are fixed first in the semi-circular track 701, followed by CD, and finally the middle E. This avoids the problem of multiple telescopic rods 9 interfering with each other in the semi-circular track 701 and causing the inability to construct at the same time.
[0076] In summary, this invention, in situations where tunnel space is limited, utilizes upper lining modules for transport, avoiding impact on equipment and personnel below. Simultaneous operations are possible, and the feeding, transporting, discharging, and assembly of the lining are all mechanically controlled, reducing the need for experienced construction workers. Furthermore, once one lining is positioned, the next lining can be connected and installed, changing traditional construction procedures and significantly improving overall work efficiency. Simultaneously, the drive component 2, located at the top of the traveling frame 1, prevents falling rocks from injuring construction personnel, providing protection during transport. The coordinated operation of the overall structure simplifies construction procedures, and with increased efficiency, construction costs decrease.
