Abstract
Description
Technical Field
[0001] This utility model relates to the field of caisson transportation technology, specifically to a caisson translation sliding plate device. Background Technology
[0002] There are two traditional methods for transporting caissons: trolley transport and airbag transport. Trolley transport is a mature technology with high safety and ease of operation, but it has a high investment cost and is generally suitable for professional permanent prefabrication yards. Airbag transport has lower foundation requirements and lower prefabrication site treatment costs, but it is more difficult to operate and has poorer construction safety, especially for caissons with a narrow width and a height-to-width ratio greater than 1, where airbag placement is difficult, the caisson's center of gravity is high, and the safety risks are even greater.
[0003] With the emergence of new materials, sliding friction can replace rolling friction for caisson transportation. For example, Zhang Xiaoming's article "Discussion on Scheme for Transporting Large Components Using Sliding Plates," published in *China High-Tech Enterprises* (No. 22, 2010), discusses the construction technology of PTFE sheet-driven caisson translation. However, the PTFE sheets have large processing dimensions and significant lateral displacement. As the caisson moves laterally with the PTFE sheets, it is prone to colliding with the limiting blocks due to inertia. This causes the actual direction of the caisson's movement to form an angle with the designed forward axis, requiring overcoming the friction between the caisson and the limiting blocks during correction. After correction and re-movement, the front end of the caisson is prone to deviating towards the other limiting block and colliding with it due to inertia. This repeated adjustment affects the caisson's traction and translation speed. Furthermore, the limiting blocks used are prefabricated and relatively large, making construction inconvenient and costly. Utility Model Content
[0004] The purpose of this invention is to address the technical problems existing in the above-mentioned methods by providing a construction method for a caisson translation sliding plate device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A caisson translation sliding plate device is characterized by comprising two track beams laid on a flat ground and a sliding plate mechanism connected to the track beams. Limiting rods for maintaining spacing are connected between the track beams. The sliding plate mechanism includes a support beam, a balance beam, an upper sliding plate, and a lower sliding plate. The lower sliding plate is connected to the top surface of the track beams. The support beam is parallel to the track beams, connected to the top surface of the lower sliding plate, and is used to support the caisson; its top surface is in direct contact with the outer wall or partition wall bottom plate of the caisson. The balance beam is located in front of the support beams, perpendicular to the track beams, with both ends connected to the top surface of the lower sliding plate. One side is connected to the support beam via a rigid tie rod, and the other side is connected to a winch wire rope. The upper sliding plate is connected to the bottom surfaces of the support beam and the balance beam, and is inserted into the upper flange plate of the track beam, sliding along the lower sliding plate.
[0007] The track beam is a double-web steel structure with a single section length of 4-6m. Both ends are welded with fixed connecting plates, and a set of rectangular insertion holes are set at equal intervals from both ends. Each set of insertion holes is arranged on the lower flange plates on both sides of the track beam. The track beam is arranged in sections longitudinally, and the connecting plates between two sections are connected by bolts. The width of the track beam can be calculated based on the self-weight of the caisson and the design compressive strength of the sliding plate to ensure that the load-bearing safety factor of the sliding plate meets the requirements.
[0008] The limiting rod is a square steel pipe structure with rectangular insert plates welded to both ends. These plates are inserted into the rectangular insertion holes on the lower flange plate between the two track beams. The longitudinal spacing of the limiting rods is 4~12m.
[0009] The support beam is a double-web steel structure, with a length greater than the width of the bottom plate in the forward direction of the caisson. Support beam baffles and support beam traction lugs are welded to the outer sides of both ends. The support beam baffles are used to fix the position of the upper slide plate when it slides. The support beam traction lugs are connected to the balance beam through rigid tie rods. Ribs are welded to both sides of the support beam to improve its load-bearing capacity and are bolted to the support beam limiting plates. The longitudinal spacing of the support beam limiting plates is no more than 1 / 2 the length of the lower slide plate segment. Each lower slide plate segment has at least two support beam limiting plates for limiting. The gap between the support beam limiting plates and the sides of the upper and lower slide plates, as well as the sides and bottom of the upper flange plate of the track beam, is 5mm. The support beam and the lower slide plate do not shift laterally on the track beam.
[0010] The balance beam is a double-web steel structure, with each end corresponding to the position of each track beam. Balance beam baffles and balance beam traction lugs are welded to its two sides. A pair of balance beam limiting plates are bolted to its lower flange. The balance beam baffles on both sides are used to fix the position when the upper slide plate slides. The balance beam traction lugs on both sides are connected to the rigid tie rod and the winch wire rope, respectively. The gap between the balance beam limiting plates and the sides of the upper and lower slide plates, as well as the sides and bottom of the upper flange of the track beam, is 5mm. The balance beam does not shift laterally on the track beam.
[0011] The rigid tie rod is a steel structure, corresponding to the position of each track beam, and is connected to the traction lug of the support beam and the traction lug of the balance beam respectively through pins.
[0012] The sliding plate is a 2cm thick PTFE plate, which is bonded to the top surface of the track beam with epoxy adhesive, and silicone grease is evenly applied to it to reduce the coefficient of friction between the PTFE plates.
[0013] The upper sliding plate is a 2cm thick PTFE plate, which is glued to the bottom surfaces of the support beam and the balance beam with epoxy adhesive and fixed between their respective baffles, protruding 5-10mm above each baffle, and slides along the lower sliding plate.
[0014] Using this invention, a winch wire rope connects to a balance beam, driving the support beams and their upper caissons to slide forward along the track beams. This ensures that the support beams on each track beam move forward synchronously, preventing lateral movement. After the caisson has moved forward a certain distance, the track beam segment and limiting rod at the rear of the caisson can be removed and transferred to the front of the caisson to extend the track beam until the caisson is transported to the designated position. The track beam segment and limiting rod can be recycled for each individual caisson. Overall, the construction operation is convenient. Regardless of the caisson's width, the track beam width can be adjusted to ensure the caisson's structural safety and center of gravity stability. Furthermore, all components of this caisson translation sliding device can be recycled, saving materials and reducing construction costs. Attached Figure Description

[0023] The track beam 1 is a double-web steel structure with a single section length of 4-6m. Both ends are welded with fixed connecting plates 101. A set of rectangular insertion holes 102 are set at equal intervals from both ends. Each set of insertion holes is arranged on the lower flange plates on both sides of the track beam 1. The track beam 1 is arranged in sections longitudinally, and the connecting plates 101 between the two sections are connected by bolts. The width of the track beam 1 can be calculated based on the self-weight of the caisson and the design compressive strength of the sliding plate to ensure that the load-bearing safety factor of the sliding plate meets the requirements.
[0024] The limiting rod 2 is a square steel pipe structure, with rectangular insert plates 201 welded to both ends. These plates are inserted into the rectangular insert holes 102 on the lower flange plate between the two track beams 1. The longitudinal spacing of the limiting rods 2 is 4~12m.
[0025] The support beam 3 is a double-web steel structure with a length greater than the width of the bottom plate in the forward direction of the caisson 8. Support beam baffles 301 and support beam traction lugs 302 are welded to the outer sides of both ends. The support beam baffles 301 are used to fix the position of the upper slide plate 7 when it slides. The support beam traction lugs 302 are connected to the balance beam 4 through rigid tie rods 5.

The longitudinal spacing of the support beam limiting plates 304 is not greater than 1 / 2 the length of the lower slide plate 6 segment. Each segment of the lower slide plate 6 has at least two support beam limiting plates 304 for limiting. The gap between the support beam limiting plates 304 and the sides of the upper and lower slide plates, as well as the sides and bottom of the upper flange plate of the track beam 1, is 5mm. The support beam 3 and the lower slide plate 6 do not shift laterally on the track beam 1.
[0026] The balance beam 4 is a double-web steel structure, with its two ends corresponding to the positions of each track beam 1.

[0027] The rigid tie rod 5 is a steel structure, corresponding to the position of each track beam 1, and is connected to the support beam traction lug 302 and the balance beam traction lug 402 respectively by pin shafts.

[0030] Example 2
[0031] A construction method using the caisson translation sliding plate device described in Example 1 includes the following steps:
[0032] S1: Attach the sliding plate. Attach the lower sliding plate 6 to the top surface of the track beam 1 using epoxy adhesive. Attach the upper sliding plate 7 to the bottom surfaces of the support beam 3 and the balance beam 4 respectively, and fix it between the support beam baffle 301 and the balance beam baffle 401, extending 5-10mm above the two baffles.
[0033] S2: Lifting caisson 8. The caisson 8 is lifted using jacks or airbags, and the lifting height is greater than the standard cross-section of the support beam 3 and track beam 1, including the lower sliding plate 6 and the upper sliding plate 7, by 3-5cm.
[0034] S3: Lay the track beam 1 and the limiting rod 2. The track beam 1 segments are longitudinally connected, and the connecting plates 101 between the two segments are connected by bolts to ensure that the longitudinal length is greater than the length of the support beam 3 and the balance beam 4 after connection. Pull the longitudinal connecting segments of the track beam into the bottom of the caisson 8 respectively. Limiting rods 2 are set between the front and rear track beams 1 of the caisson. The rectangular insert plates 201 of the limiting rods are inserted into the rectangular insert holes 102 of the lower flange plates between the two track beams.
[0035] S4: Install support beam 3 and balance beam 4. Insert support beam 3 and balance beam 4 into the upper flange of track beam 1 along support beam limiting plate 304 and balance beam limiting plate 403 respectively. Pull support beam 3 into the underside of caisson 8 along track beam 1. Connect support beam traction lug 302 and balance beam traction lug 402 with pins through rigid tie rod 5.
[0036] S5: Lowering the caisson 8. Lower the caisson 8 by manipulating the jacks or airbags and place it on the top surface of the support beam 3.
[0037] S6: Extend track beam 1. Extend track beam 1 longitudinally by connecting the connecting plate 101 between the two sections with bolts, ensuring that the total longitudinal length is greater than twice the length of the support beam 3 and the balance beam 4 after connection. A limiting rod 2 should be inserted at the front end.
[0038] S7: Winch traction. The winch wire rope 9 is connected to the traction lug 402 on the front side of the balance beam. Starting the winch drives the balance beam 4, support beam 3 and its upper caisson 8 to slide forward along the track beam 1.
[0039] S8: Transfer track beam 1 and limit rod 2. The caisson 8 moves forward, and traction is stopped when the balance beam 4 reaches the vicinity of the foremost end of the track beam 1. The track beam 1 and limit rod 2 behind the caisson are removed, and the caisson is transferred to the front of the caisson.
[0040] S9: The caisson 8 has been moved. Repeat steps S6 to S8 until the caisson is transported to the designated location and the movement is complete. Use jacks or airbags to lift caisson 8, or use a crane vessel to lift caisson 8, then remove the caisson moving slide plate device for reuse.
[0041] In step S1, the lower sliding plate 6 is a 2cm thick PTFE plate, on which silicone grease is evenly applied to reduce the coefficient of friction between the PTFE plates. The upper sliding plate 7 is a 2cm thick PTFE plate that slides along the lower sliding plate 6.
[0042] In steps S1-S4 and S6-S8, the track beam 1 is a double-web steel structure with a single section length of 4-6m. Connecting plates 101 are welded to both ends, and a set of rectangular insertion holes 102 are equidistant from both ends, with each set of holes located on the lower flange plates on both sides of the track beam 1. The track beam 1 is arranged in sections longitudinally, with connecting plates between sections connected by bolts. The width of the track beam 1 can be calculated based on the self-weight of the caisson and the design compressive strength of the sliding plate to ensure that the load-bearing safety factor of the sliding plate meets the requirements.
[0043] In steps S3, S6, and S8, the limiting rod 2 is a square steel pipe structure, with rectangular insert plates 201 welded to both ends. The limiting rods are arranged with a longitudinal spacing of 4~12m to ensure that the track beam spacing remains unchanged.
[0044] In steps S1-S8, the support beam 3 is a double-web steel structure. Support beam baffles 301 and support beam traction lugs 302 are welded to its outer surfaces at both ends. The baffles ensure the upper sliding plate 7 remains in a fixed position during sliding, and the support beam 3 can be moved along the track beam 1 via the traction lugs. Fixed ribs 303 and bolted limiting support beam limiting plates 304 are welded to both sides. The ribs improve the load-bearing capacity of the support beam 3. The longitudinal spacing of the limiting plates should not exceed 1 / 2 the length of the lower sliding plate 6 segment, ensuring that each segment of the lower sliding plate 6 has two limiting plates. The gap between the support beam limiting plate 304 and the sides of the upper and lower sliding plates, as well as the sides and bottom of the upper flange plate of the track beam 1, is 5mm, ensuring that the support beam 3 and the lower sliding plate 6 do not shift laterally on the track beam 1. The length of the support beam 3 is greater than the width of the bottom plate in the direction of the caisson's movement.
[0045] In steps S1, S3, S4, and S6-S8, the balance beam 4 is a double-web steel structure, corresponding to the position of each track beam 1. Balance beam baffles 401 and balance beam traction lugs 402 are welded to its two sides respectively. A pair of balance beam limiting plates 403 are fixed to its lower flange plate by bolts. The baffles on both sides ensure that the upper slide plate 7 is fixed in position when sliding. The traction lugs on both sides are connected to the support beam 3 and the winch wire rope 9 respectively. The gap between the limiting plate and the sides of the upper and lower slide plates, as well as the sides and bottom of the upper flange plate of the track beam 1, is 5mm to ensure that the balance beam 4 does not shift laterally on the track beam 1.
[0046] In step S4, the rigid tie rod 5 is a steel structure, corresponding to the position of each track beam 1, and is connected to the support beam traction lug 302 and the balance beam traction lug 402 respectively by pin shafts.
[0047] In step S7, the speed at which the winch pulls the caisson to slide is no more than 1 m / min.
[0048] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the protection scope of this utility model.
