Description

Technical Field

[0001] This invention relates to the field of tunnel construction equipment technology, and in particular to a complete set of equipment for precise positioning and synchronous pouring of tunnel waterstops to prevent deviation. Background Technology

[0002] In the secondary lining construction of tunnel engineering, the installation and positioning of waterstops is a crucial step in preventing water leakage at structural joints. Currently, waterstops are mostly fixed using traditional methods such as simple steel bar clips, wire binding, or wooden formwork clamps. However, these methods have the following shortcomings: 1. Traditional fixing methods lack a precise vertical adjustment mechanism, and the installation height of the waterstop relies on manual visual inspection and experience for adjustment. During the subsequent concrete pouring and vibration process, the waterstop is easily displaced or curled due to the impact force and buoyancy of the concrete, causing the center line of the waterstop to deviate from the design joint position and weakening its water-stopping effect.

[0003] The end formwork of the tunnel secondary lining trolley has a variety of shapes, but the existing fixing devices are mostly rigid and non-adjustable structures, which make it difficult to fit and install according to the actual shape of the formwork, resulting in poor equipment versatility.

[0004] Existing methods require repeated adjustments to the binding points and cannot effectively coordinate the waterstop with the anchor rods while fixing the waterstop. The process is fragmented, the construction efficiency is low, and it is difficult to guarantee the smoothness of the waterstop in long sections.

[0005] To address this, a complete set of equipment for precise positioning and simultaneous pouring of anti-deviation waterstop construction for tunnel waterstops is proposed. Summary of the Invention

[0006] In view of this, the present invention provides a complete set of equipment for precise positioning and synchronous pouring of tunnel waterstops to prevent deviation, so as to solve or alleviate one of the technical problems existing in the prior art, and at least provide a beneficial option.

[0007] The technical solution of this invention is implemented as follows: A complete set of equipment for precise positioning and synchronous pouring of anti-deviation waterstop in tunnels includes a base plate. Two support plates are symmetrically fixedly connected to the top of the base plate. A top plate is fixedly connected to the top of the support plates. A transmission box is fixedly connected to the top of the base plate. A knob is rotatably connected to the front surface of the transmission box. The knob is fixedly connected to one end of a transmission rod. A first bevel gear is fixedly connected to the other end of the transmission rod. The first bevel gear meshes with a second bevel gear. A threaded rod is fixedly connected to the top of the second bevel gear. A lifting platform is threadedly connected to the outer wall of the threaded rod. A connecting rod is symmetrically fixedly connected to the top of the lifting platform. A connecting sleeve is detachably connected to the top of the connecting rod. A first clamping plate is fixedly connected to the top of the connecting sleeve. A limit plate is fixedly connected to the top of the first clamping plate. A second clamping plate is fixedly connected to the top of the limit plate.

[0008] A further preferred embodiment: the bottom of the base plate is fixedly connected to a pad by threads.

[0009] A further preferred embodiment: a guide rod is fixedly connected to the top of the top plate, and the lifting platform is slidably connected to the outer wall of the guide rod.

[0010] A further preferred embodiment: both the first clamping plate and the second clamping plate have several through holes inside.

[0011] A further preferred embodiment: a first anchor rod or a second anchor rod is disposed inside several of the through holes.

[0012] A further preferred embodiment includes a waterproof strip provided between the first clamping plate and the second clamping plate.

[0013] A further preferred embodiment: the pad is disposed on the end template of the secondary lining trolley.

[0014] A further preferred embodiment: the first bevel gear and the second bevel gear are disposed inside the transmission box.

[0015] The embodiments of the present invention have the following advantages due to the adoption of the above technical solutions: 1. By incorporating a transmission box, knob, bevel gear set, and threaded rod structure, operators can easily rotate the knob to precisely drive the lifting platform to slide up and down along the guide rod, thereby raising and lowering the first and second clamping plates as a whole. This transmission mechanism enables continuous, fine-tuning of the waterstop installation height, improving the accuracy of waterstop positioning and solving the problem of rough manual positioning.

[0016] The waterstop is clamped between the first and second clamping plates, and under the combined action of the first or second anchor rod with through holes, the waterstop is locked in both the horizontal and vertical directions. It can withstand the lateral pressure and buoyancy generated during concrete pouring, and can prevent the waterstop from shifting up or down or left or right, ensuring that the waterstop is always in the designed waterstop section position.

[0017] The bottom pad and the base plate are designed with separate threaded connections. The pad can be replaced or the installation angle can be adjusted according to the actual shape of the end template of the secondary lining trolley, so that the whole set of equipment can fit tightly into the template surface with different curvatures or slopes, improving the versatility and installation stability of the equipment under different tunnel cross-section conditions.

[0018] The first clamping plate and the connecting rod are detachably connected by a connecting sleeve. When the width, thickness or cross-sectional shape of the waterstop changes, the clamping plate of the corresponding specification can be quickly replaced without replacing the whole machine, which reduces construction costs and expands the applicability of the equipment.

[0019] This invention integrates lifting adjustment, rigid clamping, anchor bolt limiting and template adaptation functions into one compact structure. During construction, alignment can be completed simply by turning a knob, simplifying the traditional multi-step process and improving the construction efficiency and quality pass rate of the tunnel waterproofing sub-project.

[0024] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of the invention. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0025] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0026] like Figures 1-5As shown, this embodiment of the invention provides a complete set of equipment for precise positioning and synchronous pouring of anti-deviation waterstop in tunnels. The equipment includes a base plate 1, which serves as the mounting base for the entire device, supporting and fixing the upper functional components. Two support plates 3 are symmetrically fixedly connected to the top of the base plate 1, located on the left and right sides respectively, supporting and connecting a top plate 4, while also providing clearance for the vertical movement of the lifting platform 11. A top plate 4 is fixedly connected to the top of the support plates 3, and the top plate 4 is parallel to the base plate 1, together forming the overall frame structure of the equipment, ensuring structural stability and rigidity during construction. A transmission box 5 is fixedly connected to the top of the base plate 1, located in the central area of ​​the base plate 1. The transmission box 5 houses the transmission mechanism, protecting the transmission components and preventing dust. A knob 6 is rotatably connected to the front surface of the transmission box 5, exposed on the front side for easy gripping and rotation by the operator. The knob 6 is fixedly connected to one end of a transmission rod 7, and rotating the knob 6 synchronously drives the transmission rod 7 to rotate. The other end of the transmission rod 7 is fixedly connected to a first bevel gear 8, which meshes with a second bevel gear 9. The transmission rod 7 drives the first bevel gear 8 to rotate, and the first bevel gear 8 converts the horizontal rotational motion into the vertical rotational motion of the second bevel gear 9 through bevel gear meshing. A threaded rod 10 is fixedly connected to the top of the second bevel gear 9, and when the second bevel gear 9 rotates, it drives the threaded rod 10 to rotate synchronously. A lifting platform 11 is threadedly connected to the outer wall of the threaded rod 10. A threaded hole adapted to the threaded rod 10 is opened in the middle of the lifting platform 11. When the threaded rod 10 rotates, it drives the lifting platform 11 to move up and down along the axis of the threaded rod 10 through the action of the threaded transmission pair, realizing the lifting adjustment function. Two connecting rods 12 are symmetrically fixedly connected to the top of the lifting platform 11, and are fixed to the left and right sides of the top of the lifting platform 11 respectively, for transmitting the lifting motion of the lifting platform 11 to the upper clamping plate assembly. A connecting sleeve 14 is detachably connected to the top of the connecting rod 12. The connecting sleeve 14 is fitted onto the outer side of the top of the connecting rod 12, and the two are detachably fixed by bolts or clips, facilitating the replacement of clamps of different specifications according to the cross-sectional shape and size of the waterstop. A first clamp 15 is fixedly connected to the top of the connecting sleeve 14. The first clamp 15 serves as the bottom support plate of the waterstop, supporting it from below. A limiting plate 16 is fixedly connected to the top of the first clamp 15. The limiting plate 16 is vertically positioned between the first clamp 15 and the second clamp 17, used to limit the installation position of the waterstop, preventing it from shifting back and forth in the horizontal direction and ensuring that the edges of the waterstop are neatly aligned. A second clamp 17 is fixedly connected to the top of the limiting plate 16. The second clamp 17 is parallel to and spaced apart from the first clamp 15, with the distance between them matching the thickness of the waterstop, used to press the waterstop from above. Together with the first clamp 15, they form a clamping structure for holding the waterstop.

[0027] In this embodiment, specifically: a pad 2 is threadedly fixed to the bottom of the base plate 1. The pad 2 and the base plate 1 are separate and detachable structures. The shape of the lower surface of the pad 2 can be customized according to the actual contour of the end template of the tunnel lining trolley. When the surface of the end template is flat, curved, or inclined, a pad 2 with a corresponding bottom shape can be replaced to ensure that the pad 2 fits tightly against the template surface, ensuring that the entire equipment is firmly installed on the template, thereby improving the versatility and adaptability of the equipment. The pad 2 and the base plate 1 are connected by threads, which facilitates quick assembly, disassembly, and replacement on the construction site.

[0028] In this embodiment, specifically: a guide rod 13 is fixedly connected to the top of the top plate 4, and the lifting platform 11 is slidably connected to the outer wall of the guide rod 13. The guide rod 13 is vertically arranged, and its lower end passes through the edge of the lifting platform 11 and is fixed to the top plate 4. The guide rod 13 is arranged parallel to the threaded rod 10. A guide hole is opened at the corresponding position of the lifting platform 11 to slide with the guide rod 13. When the lifting platform 11 moves up and down under the drive of the threaded rod 10, the guide rod 13 plays a guiding and limiting role for the lifting platform 11, preventing the lifting platform 11 from rotating horizontally or swaying during the rising or falling process, ensuring that the lifting platform 11 only moves in the vertical direction, thereby ensuring that the first clamping plate 15 and the second clamping plate 17 always remain in a horizontal state, so that the waterstop is clamped and the force is evenly distributed.

[0029] In this embodiment, specifically: both the first clamping plate 15 and the second clamping plate 17 have a plurality of through holes 18 inside. The through holes 18 are evenly distributed along the length of the first clamping plate 15 and the second clamping plate 17, and the axial direction of the through holes 18 is perpendicular to the surface of the first clamping plate 15 and the second clamping plate 17. The through holes 18 are used for anchor rods to pass through, so that the anchor rods can penetrate the clamping plates and extend to the upper and lower sides of the waterstop, providing an installation channel for subsequent installation of anchor rods.

[0030] In this embodiment, specifically: a first anchor rod 19 or a second anchor rod 20 is provided inside several through holes 18. The first anchor rod 19 is located below the waterproof strip and passes through the through hole 18 of the first clamping plate 15, used to support the waterstop strip from below, preventing it from sagging due to its own weight or vibration impact during concrete pouring. The second anchor rod 20 is located above the waterproof strip and passes through the through hole 18 of the second clamping plate 17, used to press and limit the waterstop strip from above, preventing it from shifting upwards due to concrete buoyancy or lateral impact. After the first anchor rod 19 and the second anchor rod 20 pass through the first clamping plate 15 and the second clamping plate 17, their two ends extend out to both sides of the clamping plate, forming two physical limiting barriers above and below the waterstop strip. Together with the first clamping plate 15 and the second clamping plate 17, they constitute a locking system, resisting the offset forces generated in all directions throughout the concrete pouring process.

[0031] In this embodiment, specifically: a waterproof strip is provided between the first clamping plate 15 and the second clamping plate 17. The waterproof strip is laid horizontally on the upper surface of the first clamping plate 15, and its rear edge abuts against the front surface of the limiting plate 16. The limiting plate 16 limits the horizontal position of the waterproof strip. The second clamping plate 17 presses against the upper surface of the waterproof strip from above, and the waterproof strip is fixed in the designed position by the clamping force of the first clamping plate 15 and the second clamping plate 17.

[0032] In this embodiment, specifically: the pad 2 is set on the end template of the secondary lining trolley. In use, the pad 2 is first selected and installed on the bottom of the base plate 1 according to the actual shape of the end template, and then the pad 2 is placed stably and fixed on the end template of the secondary lining trolley, so that the installation posture of the entire set of equipment on the template matches the template surface, ensuring that the installation position of the waterstop is consistent with the tunnel design section.

[0033] In this embodiment, specifically: the first bevel gear 8 and the second bevel gear 9 are disposed inside the transmission housing 5. The transmission housing 5 completely encloses the first bevel gear 8 and the second bevel gear 9 within its inner cavity, which can prevent external mud and dust from adhering to the surface of the bevel gears and affecting the transmission accuracy and lifespan, improve the safety of equipment operation, and avoid personnel injury caused by exposed rotating parts.

[0034] In operation, this invention works as follows: Based on the actual shape of the tunnel lining trolley end template, a pad 2 with a matching bottom shape is selected. The pad 2 is then threadedly fixed to the bottom of the base plate 1. The pad 2 is then placed stably and fixed at the designated installation position on the lining trolley end template, ensuring a tight fit and secure installation of the entire device with the end template. Next, based on the width, thickness, and cross-sectional shape of the waterstop to be installed, a first clamping plate 15 and a second clamping plate 17 of corresponding specifications are selected. The first clamping plate 15 and the second clamping plate 17 are then integrally installed on the top of the connecting rod 12 via the connecting sleeve 14, completing the rapid replacement and assembly of the clamping plates.

[0035] The operator holds knob 6 and rotates it clockwise or counterclockwise. Knob 6 drives transmission rod 7 to rotate synchronously. Transmission rod 7 drives first bevel gear 8 to rotate. First bevel gear 8 drives second bevel gear 9 to rotate through meshing transmission. Second bevel gear 9 drives threaded rod 10 to rotate. Threaded rod 10 drives lifting platform 11 to move up and down along the axis of threaded rod 10 through threaded transmission pair. When lifting platform 11 moves, its edge slides along the outer wall of guide rod 13. Guide rod 13 constrains and guides the movement direction of lifting platform 11 to prevent deflection. Lifting platform 11 drives first clamping plate 15 and second clamping plate 17 to rise or fall as a whole through connecting rod 12 and connecting sleeve 14 until the upper surface height of first clamping plate 15 is completely consistent with the design requirement for waterstop installation height, achieving precise positioning of waterstop installation elevation.

[0036] The waterstop is laid horizontally on the upper surface of the first clamping plate 15. The waterstop is pushed until its rear edge abuts against the front surface of the limiting plate 16. The limiting plate 16 precisely limits the front-to-back position of the waterstop in the horizontal direction, ensuring that the longitudinal position of the waterstop meets the design requirements. First anchor rods 19 are inserted into the corresponding through holes 18 of the first clamping plate 15 and the second clamping plate 17 below the waterstop, and second anchor rods 20 are inserted into the corresponding through holes 18 of the first clamping plate 15 and the second clamping plate 17 above the waterstop. The second clamping plate 17 is pressed against the upper surface of the waterstop from above, clamping and fixing the waterstop between the first clamping plate 15 and the second clamping plate 17. Lateral positioning is achieved through the limiting plate 16, thus fixing the position of the waterstop.

[0037] During the pouring process, when the impact force, lateral pressure, and buoyancy of the concrete act on the waterstop, the first anchor rod 19 and the second anchor rod 20 provide reverse restraint forces from the upper and lower directions respectively, preventing the waterstop from shifting or deviating due to the impact or buoyancy of the concrete. At the same time, the first clamping plate 15, the second clamping plate 17, and the limiting plate 16 form a full-circumferential mechanical restraint on the waterstop, ensuring that the waterstop remains on the center line of the designed waterstop section throughout the entire concrete pouring and vibration process, achieving precise positioning and anti-deviation waterstop construction. After the pouring is completed, the connection between the connecting sleeve 14 and the connecting rod 12 is released, and the two sets of clamping plates are removed. The anchor rods and the waterstop can then be left in the poured concrete. The bottom plate 1, support plate 3, top plate 4, lifting platform 11, and transmission components can be separated from the connecting sleeve 14 by the connecting rod 12 and removed, allowing for the reuse of the equipment.

[0038] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in the present invention, and these should all be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
