Description

Technical Field

[0001] This invention relates to the field of tunnel construction technology, and in particular to a pre-reserved grouting guide hole device for tunnel trolley lining. Background Technology

[0002] Tunnels are a common engineering structure. As permanent projects, medium and long tunnels are generally lined with reinforced concrete using steel formwork trolleys. In view of the tunnel lining construction process and the geological conditions of the project, backfill grouting is designed at the top arch of the tunnel, and consolidation grouting is designed in sections with poor geological conditions. Both types of grouting are covered grouting carried out after the reinforced concrete lining.

[0003] When backfilling or consolidation grouting, if holes are drilled directly into the lining concrete, the drill bit is prone to colliding with the reinforcing steel, causing the steel to be interrupted and the structure to be damaged. Moreover, re-drilling holes will create artificial holes in the concrete structure, reducing the structural stability. Therefore, it is necessary to reserve guide holes in the reinforced concrete during lining. When re-grouting, the drilling rig is aligned with the guide hole, drills to a certain depth, reaches the grouting section, cleans the hole, and then connects the grouting pipe to carry out grouting. The current technology for reserving grouting guide holes generally involves burying PVC pipes, using a pneumatic drill to clean the hole during grouting, and then drilling to the required depth for grouting. After grouting, the guide hole is sealed.

[0004] The existing technology involves pre-drilling grouting guide holes. During construction, the positioning section of the guide rod passes through the pre-drilled guide hole in the tunnel trolley formwork and through the structural steel reinforcement mesh. The guide rod is positioned by tightening the threaded section of the guide rod to the threaded guide hole of the pad plate. This allows the guide rod to be detachably connected to the tunnel trolley formwork. Then, during the tunnel trolley lining, the guide rod is removed by tightening the threaded section of the guide rod positioning section through the pre-drilled guide hole. The inner wall of the pre-drilled guide hole is made of concrete, which facilitates subsequent drilling, grouting, and sealing. The guide hole has good quality and sealing effect. However, the insertion and removal of the guide rod are all done manually, which is inefficient and affects the overall project progress. In addition, manual operation has many uncertainties and safety hazards. Summary of the Invention

[0037] Example 1

[0038] Reference Figure 1 A schematic diagram of the overall structure of a pre-reserved grouting guide hole device for tunnel trolley lining is provided, as shown below. Figure 1-5 A pre-reserved grouting guide hole device for tunnel trolley lining, comprising:

[0039] The guide hole portion 100 includes a carrier assembly 101 and a fixed hole assembly 102 installed on one side of the carrier assembly. The carrier assembly 101 includes a template 101a and a rectangular panel 101b welded to the outside of the template 101a. A circular hole 101c is opened on the surface of the template 101a corresponding to the center of the rectangular panel 101b. A sealing block 101d is movably embedded in the center of the rectangular panel 101b, and a cavity 101e is opened inside the rectangular panel 101b on one side of the sealing block 101d. An insertion hole 101f communicating with the circular hole 101c is opened at the center of the sealing block 101d.

[0040] Specifically, a notch is provided on the surface of the rectangular panel 101b at the position corresponding to the sealing block 101d. The size of the notch is equal to the size of the sealing block 101d, so that the sealing block 101d can be embedded in the notch.

[0041] The flipping part 200 includes a hinge component 1 201 fixed to one side of the surface of the rectangular panel 101b and a hinge component 202 fixed to the surface of the sealing block 101d near the sealing block 101d. The hinge component 1 201 and the hinge component 202 are connected by a rotating assembly 203.

[0042] The locking portion 300 includes a locking element 301 installed in the cavity 101e for opening and closing the sealing block 101d.

[0043] Furthermore, the fixed hole assembly 102 includes a hollow cylinder 102a fixedly inserted into the sealing block 101d and a hydraulic telescopic rod 102b fixedly installed at the tail end of the hollow cylinder 102a. A positioning rod 102c is provided inside the hollow cylinder 102a, and one end of the positioning rod 102c is fixedly connected to the hydraulic telescopic rod 102b.

[0044] Specifically, the positioning rod 102c has a hollow internal structure, which has the advantages of being lightweight and having high rigidity. Furthermore, the insertion end of the positioning rod 102c has a pointed cone structure, which makes it easier to insert into the template 101a.

[0045] Specifically, the diameter of the round hole 101c is larger than the diameter of the insertion hole 101f, and a disc is fixed to the outside of the positioning rod 102c. The disc fits against the end of the round hole 101c to achieve the function of sealing the hole.

[0046] Specifically, during use, a circular hole 101c is first made on the template 101a. After the rectangular panel 101b is notched, it is welded to the template 101a. During welding, it is ensured that the axis of the circular hole 101c is coaxial with the center of the notched groove. Then, the rectangular panel 101b and the sealing block 101d are rotatably connected by the flipping part 200. The side of the rectangular panel 101b and the sealing block 101d away from the flipping part 200 is locked by the locking part 300. Before the concrete is poured, the hydraulic telescopic rod 102b is extended to drive the positioning rod 102c through the circular hole 101c and into the template 101a. After the concrete is fixed, the hydraulic telescopic rod 102b retracts to drive the positioning rod 102c into the hollow cylinder 102a. The extension and retraction of the positioning rod 102c do not require manual operation, which improves the overall work efficiency and solves many hidden dangers of manual operation, ensuring the safety of the project.

[0047] Meanwhile, after the locking part 300 is opened, the flipping part 200 can drive the sealing block 101d to open and form a window, which makes it easier for operators to observe whether there are steel bars blocking the template, and facilitates timely handling of the blocking steel bars, thus reducing the difficulty of operation.

[0048] Furthermore, the hinge component 201 includes a support base 201a, with protrusions 201b symmetrically fixed on one side of the support base 201a, and a sliding cover 201c fixed on the outer side of the support base 201a between the two protrusions 201b. A sliding groove 201d is provided on the opposite side of the two protrusions 201b, and a limiting groove 201e communicating with the sliding groove 201d is provided on the opposite side of the two protrusions 201b. A rotating groove 201f is provided at one end of the limiting groove 201e, and a movable groove 201g is provided through the surface of the two protrusions 201b on one side of the rotating groove 201f.

[0049] Furthermore, hinge component 202 includes a flip seat 202a fixed to the surface of the sealing block 101d, and a connector 202b extending between two protrusions 201b is symmetrically fixed on one side of the flip seat 202a.

[0050] Furthermore, the rotating assembly 203 includes a linkage 203a and a pusher 203b for driving the linkage.

[0051] Furthermore, the linkage 203a includes bearing seats 203a-1 that are slidably disposed in the two slide grooves 201d and a rotating rod 203a-2 that passes through the movable groove 201g and the connector 202b. A rotating shaft 203a-3 is rotatably connected between the two bearing seats 203a-1. A rectangular limiting block 203a-4 is fixedly sleeved on the outside of the rotating shaft 203a-3 at the position corresponding to the two limiting grooves 201e. A small gear 203a-5 is fixedly sleeved on the outside of the rotating shaft 203a-3 at the middle position. A large gear 203a-6 that meshes with the small gear 203a-5 is fixedly sleeved on the outside of the rotating rod 203a-2.

[0052] Specifically, a connecting rod connected to the rotating shaft 203a-3 is sleeved on the outside of the rotating rod 203a-2, and the connecting rod is rotatably connected to both the rotating rod 203a-2 and the rotating shaft 203a-3.

[0053] Specifically, the width of the slide groove 201d is greater than the width of the limiting groove 201e. The rectangular limiting block 203a-4 slides in the limiting groove 201e. The opening position of the rotating groove 201f corresponds to the rectangular limiting block 203a-4, so that the rectangular limiting block 203a-4 will not rotate in the limiting groove 201e, but will only slide. When the rectangular limiting block 203a-4 moves into the rotating groove 201f, it will not be restricted. Therefore, the rectangular limiting block 203a-4 will rotate under the action of external force.

[0054] Furthermore, the pusher 203b includes a rack 203b-1 slidably disposed inside the sliding cover 201c and a pneumatic telescopic rod 203b-2 installed on the outside of the sliding cover 201c. Guide blocks 203b-3 are fixed on both sides of the rack 203b-1 near the end position. The telescopic end of the pneumatic telescopic rod 203b-2 is fixed with a linkage rod 203b-4 that is fixedly connected to the two guide blocks 203b-3 respectively.

[0055] Specifically, guide grooves are provided on both the upper and lower sides of the sliding cover 201c. The inner diameter of the guide groove is adapted to the width of the guide block 203b-3, so the guide block 203b-3 will restrict the sliding in the guide groove.

[0056] Operation process: A circular hole 101c is made in the template 101a. After the rectangular panel 101b is notched, it is welded to the template 101a. During welding, it is ensured that the axis of the circular hole 101c is coaxial with the center of the notched groove. Then, the rectangular panel 101b and the sealing block 101d are rotatably connected by the flipping part 200. The side of the rectangular panel 101b and the sealing block 101d away from the flipping part 200 is locked by the locking part 300. Before the concrete is poured, the hydraulic telescopic rod 102b is extended to drive the positioning rod 102c through the circular hole 101c and into the template 101a. After the concrete is fixed, the hydraulic telescopic rod 102b retracts to drive the positioning rod 102c into the hollow cylinder 102a. The extension and retraction of the positioning rod 102c do not require manual operation, which improves the overall work efficiency and solves many hidden dangers of manual operation, ensuring the safety of the project.

[0057] Meanwhile, after the locking part 300 is opened, the flipping part 200 can drive the sealing block 101d to open and form a window, which makes it easier for operators to observe whether there are steel bars blocking the template, and to deal with the blocking steel bars in time, thus reducing the difficulty of operation.

[0058] When the flipping part 200 is in operation, the pneumatic telescopic rod 203b-2 extends, driving the rack 203b-1 to slide in the sliding cover 201c. At the same time, the rack 203b-1 meshes with the pinion 203a-5. Since the rectangular limiting block 203a-4 is restricted in the limiting groove 201e at this time, the rotation of the pinion 203a-5 is restricted. Therefore, only one thrust is given to the pinion 203a-5. The thrust causes the rotating shaft 203a-3 to drive the bearing seats 203a-1 at both ends to slide in the sliding groove 201d. At the same time, the push of the rotating shaft 203a-3, through the connecting rod and the thrust of the pinion 203a-5, causes the rotating rod 203a-2 to move in the movable groove 201g. The movement of the rotating rod 203a-2 will drive the sealing block 101d to exit from the notch through the hinge part 202.

[0059] When the rotating rod 203a-2 moves to one end of the movable slot 201g, the sealing block 101d completely exits from the notch. At the same time, the rectangular limiting block 203a-4 moves to the rotating slot 201f, while the pneumatic telescopic rod 203b-2 continues to extend. Therefore, the rack 203b-1 will still push the pinion 203a-5. Since the rectangular limiting block 203a-4 is unrestricted in the rotating slot 201f, the pinion 203a-5 drives the large gear 203a-6 to rotate. After the large gear 203a-6 rotates, it drives the rotating rod 203a-2 to rotate. Therefore, the sealing block 101d will be flipped through the hinge 202. This structure has a pull-out process before flipping, so that the sealing block 101d exits from the notch of the rectangular panel 101b. This solves the problem that the sealing block cannot be opened due to the notch restriction when flipping directly, and improves practicality.

[0060] Example 2

[0061] Reference Figure 6 The difference between this embodiment and the first embodiment is that the lock 301 includes a push plate 301a disposed in the cavity 101e, a lock pin 301b fixed on one side of the push plate 301a near both ends, and a guide pin 301c movably passes through the middle section of the push plate 301a. The two ends of the guide pin 301c are respectively fixed to the inner side of the cavity 101e, and a spring 301d is sleeved on the outside of the guide pin 301c.

[0062] A locking block 301e is fixed on one side of the push plate 301a, and a lever block 301f is fixed on one side of the locking block 301e at the middle position.

[0063] Specifically, the inner side of the rectangular panel 101b and one side of the sealing block 101d are provided with interconnected lock holes. There are two lock holes, which correspond to the position of the lock pin 301b. After the lock pin 301b is inserted into the lock hole, it locks the sealing block 101d.

[0064] The rest of the structure is the same as in Example 1.

[0065] Operation process: A strip groove communicating with the cavity 101e is opened on the surface of the rectangular panel 101b. The toggle block 301f is located in the strip groove. A pin is movable at one end of the strip groove. A pin hole is opened on the toggle block 301f. When opening, the toggle block 301f is moved along the strip groove and the spring 301d is compressed, which in turn drives the locking pin 301b to exit from the lock hole, releasing the lock on the sealing block 101d. At this time, the toggle block 301f is located at the pin position. The pin is inserted into the pin hole to form a restriction. When locking, the pin is pulled out. Under the reaction force of the spring 301d, it is reset. Therefore, the locking pin 301b is inserted into the lock hole again to complete the locking.

[0066] Example 3

[0067] Reference Figure 7 This embodiment differs from the previous embodiment in that the locking part 300 also includes a disc lock 302, which is rotatably installed inside the cavity 101e and located on one side of the locking block 301e.

[0068] The disc lock 302 includes a rotating rod 302a fixed in the cavity 101e. One end of the rotating rod 302a is rotatably connected to a first disc 302b and a second disc 302c from the outside to the inside. A drive disc 302d is provided on one side of the first disc 302b. A rotating rod 302e extending through the cavity 101e to the outside of the sealing block 101d is fixed at the axis of one side of the drive disc 302d. A digital knob 302f is fixed at one end of the rotating rod 302e. A slot 302g is provided on the outer side of the first disc 302b, the second disc 302c and the drive disc 302d. A protrusion 302h is fixed on both sides of the first disc 302b near the edge. A protrusion 302i is fixed on the edge of the second disc 302c near the first disc 302b. A protrusion 302j is fixed on the edge of the drive disc 302d near the first disc 302b.

[0069] Specifically, the depth of the slot 302g is equal to the length of the card block 301e, so that the card block 301e can be inserted into the slot 302g;

[0070] Specifically, the outer periphery of the digital knob 302f is equidistantly arranged with numbers, three of which correspond to three slots 302g respectively. Rotating according to the corresponding numbers causes the three slots 302g to overlap and face the card block 301e.

[0071] The rest of the structure is the same as in Example 2.

[0072] Operation process: When unlocking, rotate the digital knob 302f clockwise until it reaches the first number. During the rotation, the drive disk 302d will rotate. When the protrusion 302j on one side of the drive disk 302d is in contact with the protrusion 302h on one side of the wheel disk 302b, it will rotate accordingly. At the same time, when the protrusion 302h is in contact with the protrusion 302i, the wheel disk 302c will rotate. It will stop when it reaches the corresponding number. At this time, the slot 302g of the wheel disk 302c will face the locking block 301e.

[0073] Next, rotate the digital knob 302f counterclockwise to the second number, drive the disk 302d to rotate, and the third protrusion 302j drives the first protrusion 302h, so that the slot 302g of the first disk 302b also faces the locking block 301e. Finally, rotate the digital knob 302f clockwise to the third number, so that the slot 302g on the drive disk 302d also faces the locking block 301e. At this time, the three slots 302g overlap. Move the lever 301f to make the locking block 301e enter the slot 302g, so that the locking pin 301b can be removed from the lock hole.

[0074] After locking, rotating the digital knob 302f shuffles the sequence, so that the slot 302g is not facing the locking block 301e. At this time, since the slot 302g is not facing the locking block 301e, the backward movement of the locking block 301e is restricted, so it cannot be opened normally, thus playing a protective role and preventing other operators from operating it incorrectly.
