Hoisting and pouring device for secondary lining construction of arch part by hole pile method

Abstract

A lifting and pouring device for the arch lining construction of a tunnel-pile method is disclosed. The device includes a movable template, comprising a vertically lifting arch box and horizontally retractable vertical boxes located on the left and right sides in the direction of travel. First flaps are symmetrically arranged on the side walls of the arch box, and second flaps are symmetrically arranged on the side walls of the vertical boxes. Grouting holes are provided on the arch box. When the template needs to form a pouring cavity with the tunnel, the top surfaces of the arch box and vertical boxes, along with the first and second flaps, cooperate with the tunnel inner wall to form a closed pouring cavity. When the template needs to move, the vertical boxes can retract to allow space for the arch box to descend, and the arch box detaches from the tunnel inner wall after descending. The arch box and vertical boxes of this invention can be raised, lowered, and folded separately, supporting the tunnel and preventing collapse during secondary lining pouring. The template, in conjunction with the tunnel inner wall, can form a closed pouring cavity, facilitating concrete pouring. The entire device is equipped with a self-propelled system, facilitating concrete demolding and the movement of the vehicle-mounted mold, making it highly efficient and convenient.

Description

Technical Field

[0001] This invention relates to the field of construction, specifically to a lifting and pouring device for the secondary lining construction of an arch using the tunnel-pile method. Background Technology

[0002] The tunnel-pile method is generally used in the construction of underground stations. Unlike the cut-and-cover method, it involves excavating several small tunnels underground, then constructing side and center piles within the tunnels. After the side and center piles are completed, the side and center longitudinal beams are installed, followed by the top structure. Construction then proceeds under the protection of these beams. Essentially, it transfers the bored piles, beams, and columns of the cut-and-cover method underground. Its advantages include ensuring surface stability and structural safety without disrupting surface traffic. Support and secondary concrete lining are required within the tunnels to prevent collapse.

[0003] CN214062992U discloses "An Integrated Casting Device for Tunnel Secondary Lining and Cable Trench," which includes a top secondary lining template and a U-shaped support plate. The U-shaped support plate is located at the bottom of the top secondary lining template, and side secondary lining templates are movably connected to both sides of the top secondary lining template. This integrated casting device for tunnel secondary lining and cable trench uses a first fixing bolt to fix the top secondary lining template, and then uses a second fixing bolt to fix the side secondary lining templates. Universal wheels facilitate the transport of the template. When it reaches the designated position, a threaded sleeve and threaded rod drive the U-shaped support plate downwards, thereby avoiding excessive friction between the cable trench template and the ground, which could cause damage. After use, the top and side secondary lining templates can be removed by reversing the above operations, making transportation more convenient. This achieves the goal of easier assembly and disassembly, and more convenient transportation.

[0004] Its shortcomings are: 1. The U-shaped support plate must be moved and disassembled as a whole and cannot be folded individually, so its function is relatively simple; 2. It does not have the function of being a mold for tunnel pouring, which is not conducive to improving efficiency; 3. Because it does not have the function of being a mold, it is also impossible to apply release agent to the template. Summary of the Invention

Those skilled in the art can understand the specific meaning of the above terms in the embodiments of the present invention based on the specific circumstances.

[0042] like Figures 1 to 3 As shown, a lifting and pouring device for the arch lining construction of the tunnel pile method is provided. The device includes a car body 1, a driving channel 2 is provided below the car body 1, wheels 3 are provided on both sides of the bottom surface of the car body 1, the forward direction of the car body 1 is the front side, and a template is provided on the top surface of the car body 1. The template includes a liftable arch top box and horizontally retractable vertical boxes 12 located on the left and right sides.

[0043] The top surface of the car body 1 is also provided with a first arc-shaped groove 4. The axis of the first arc-shaped groove 4 is parallel to the forward direction of the car body 1. The two ends of the first arc-shaped groove 4 are located on the left and right sides of the car body 1. A lifting arched box is provided in the first arc-shaped groove 4. A receiving groove 5 is symmetrically provided on the left and right sides of the car body 1. A retractable vertical box 12 is provided in each receiving groove 5. The arched box and the vertical box 12 cooperate with the inner wall of the tunnel to form a casting cavity.

[0044] The outer wall of the vehicle body 1 is also provided with a coating unit that can apply release agent to the dome box and the vertical box 12.

[0045] In this embodiment, the vehicle body is moved into the excavated tunnel, the arched box in the first arc-shaped groove is raised vertically, and then the path for the two vertical boxes to extend and retract laterally is made. The two vertical boxes extend diagonally downwards, with one end of the vertical box in contact with the ground and the other end in contact with the bottom of the arched box. The arched box and the two vertical boxes on both sides form a mold, which, together with the inner wall of the tunnel, forms a complete closed cavity, and then concrete is poured for casting.

[0046] Before the dome box and the vertical box extend, the coating unit applies a release agent to the top surface of the dome box and the vertical box.

[0047] like Figures 4 to 5 As shown, the dome box includes several arc-shaped boxes 6 that can cooperate to form an arc segment. All arc-shaped boxes 6 are located in the first arc-shaped groove 4. Several first circular holes 7 are evenly opened on the top surface of the arc-shaped box 6 around the axis of the arc-shaped box 6. A first telescopic rod 8 corresponding to the first circular hole 7 is provided in the arc-shaped box 6. The first telescopic rod 8 is installed on the bottom surface of the arc-shaped box 6. The telescopic end of the first telescopic rod 8 points to the first circular hole 7 and is fixedly connected to a first disc 9. The first disc 9 can extend out from the first circular hole 7. A first cylindrical enclosure 10 is fixedly connected to the side of the first disc 9 facing the inside of the arc-shaped box 6. The first cylindrical enclosure 10 is coaxial with the first disc 9. The diameter of the first cylindrical enclosure 10, the first disc 9 and the first circular hole 7 are the same. First flap assemblies are symmetrically arranged on the front and rear outer walls of the arc-shaped box 6.

[0048] Several third telescopic rods 11, corresponding one-to-one with the arc-shaped box 6, are installed on the inner bottom surface of the first arc-shaped groove 4. The telescopic direction of the third telescopic rods 11 is perpendicular to the ground, and the telescopic end of the third telescopic rods 11 is fixedly connected to the bottom surface of the arc-shaped box 6.

[0049] In this embodiment, the arc-shaped box faces the inner wall of the tunnel. The first telescopic rod extends, driving the first disc to extend from the first circular hole. Several first discs provide initial support for the inner wall of the tunnel to prevent collapse. When subsequent processes are required, the first telescopic rod retracts in time, and the third telescopic rod pushes the arc-shaped box upward. Then, the vertical box extends out of the combined forming cavity to pour concrete. During concrete pouring, the first telescopic rod drives the first disc to extend and retract, impacting the concrete slurry and reducing cavities and air bubbles. The first cylindrical enclosure can prevent concrete slurry from entering the arc-shaped box. After pouring is completed, the third telescopic rod drives the arc-shaped box to descend.

[0050] like Figures 6 to 8 As shown, the vertical box 12 is located in the receiving slot 5. Several second circular holes 13 are opened on the side wall of the vertical box 12 away from the car body 1.

The second disc 15 can extend out from the second circular hole 13. A second cylindrical enclosure 16 is fixedly connected to the side of the second disc 15 facing the inside of the vertical box 12. The second cylindrical enclosure 16 is coaxial with the second disc 15. The second cylindrical enclosure 16, the second disc 15 and the second circular hole 13 have the same diameter. Second flap assemblies are symmetrically arranged on the front and rear outer walls of the vertical box 12.

[0051] A fourth telescopic rod 17 is installed on the inner wall of the receiving slot 5 near the car body 1. The telescopic end of the fourth telescopic rod 17 points out of the receiving slot 5 and is fixedly connected to the vertical box 12. The telescopic direction of the fourth telescopic rod 17 forms an angle with the ground.

[0052] In this embodiment, the vertical box faces the tunnel sidewall. The second telescopic rod extends, driving the second disc to extend from the second circular hole. Several second discs provide initial support for the tunnel sidewall. When subsequent processes are required, the second telescopic rod retracts in time. After the arc-shaped box rises, the fourth telescopic rod pushes the vertical box to slide out, combining with the arc-shaped box to form a cavity for concrete pouring. During concrete pouring, the second telescopic rod drives the second disc to extend and retract, impacting the concrete slurry and reducing cavities and air bubbles. The second cylindrical enclosure can prevent concrete slurry from flowing into the vertical box. After pouring is completed, the fourth telescopic rod drives the vertical box to retract into the receiving trough, and then the arc-shaped box can descend.

[0054] The second flap assembly includes a second rotating shaft 25. A second mounting base 26 is fixedly connected to the outer wall of the vertical box 12 in the front-rear direction. The second rotating shaft 25 is rotatably mounted on the second mounting base 26. The axis of the second rotating shaft 25 is perpendicular to the ground. A second connecting block 27 is fixedly connected to the outer circumference of the second rotating shaft 25. A second flap 28 is fixedly connected to the other end of the second connecting block 27. One end of the second rotating shaft 25 extends out of the second mounting base 26 and is fixedly connected to a third bevel gear 29. A second motor 30 is installed inside the vertical box 12. The output shaft of the second motor 30 extends through the outer wall of the vertical box 12 in the front-rear direction to the outside of the vertical box 12 and is fixedly connected to a fourth bevel gear 31. The fourth bevel gear 31 meshes with the third bevel gear 29.

[0055] In this embodiment, under normal conditions, the first and second flaps are folded outwards to expose the inner surfaces, making it easier for the application unit to apply the release agent.

[0056] When pouring is required, the first motor drives the first rotating shaft, which in turn drives the first flap to flip up. The second motor drives the second rotating shaft, which in turn drives the second flap to flip up. After each of the first and second flaps flips up alternately, a complete cavity is formed. Then, the edges of the flaps point towards the inner wall of the tunnel. The third telescopic rod pushes the arc-shaped box, and the fourth telescopic rod pushes the vertical box. The first and second flaps are inserted into the soil of the inner wall of the tunnel.

[0057] After the concrete is poured, the vertical box retracts, the arc-shaped box descends, and the first and second motors drive the first and second flaps to flip outwards to release the concrete from the mold.
