Description

Technical Field

[0001] The present invention relates to the technical field of caisson transportation, and particularly relates to a construction method for a caisson translation skateboard device. Background Art

[0002] There are two traditional processes for caisson transportation: trolley transportation and airbag transportation. The trolley transportation process is mature, with high safety and easy operation, but it has a high investment cost and is generally applicable to professional permanent prefabrication yards. The airbag transportation has low requirements for the foundation and low treatment costs for the prefabrication site, but the transportation operation is difficult and the construction safety is poor. Especially for caissons with a small width and a height-width ratio greater than 1, it is difficult to arrange airbags, the center of gravity of the caisson is high, and the safety risk is greater.

[0003] With the emergence of new materials, sliding friction can be used instead of rolling friction for caisson transportation. For example, in the article "Discussion on the Scheme of Sliding Plate Transportation of Large Components" published by Zhang Xiaoming in "China High-Tech Enterprises" NO.22, 2010, the construction technology of translating caissons with tetrafluoroethylene plates was discussed. However, the processed size of the tetrafluoroethylene plates is large and the lateral displacement is relatively large. The caisson moves laterally with the tetrafluoroethylene plate and is prone to collide with the limit block under the action of inertia. The actual movement direction of the caisson forms an angle with the designed forward axis. When correcting the deviation, the friction force between the caisson and the limit block needs to be overcome; after the caisson moves again after correcting the deviation, the front end of the caisson is prone to deviate to the other limit block and collide with it under the action of inertia. Repeated adjustments like this affect the traction translation speed of the caisson. In addition, the limit uses precast blocks, which also have a large size, inconvenient construction operation and high cost. Summary of the Invention

[0004] The purpose of the present invention is to provide a construction method for a caisson translation skateboard device aiming at the technical problems existing in the above-mentioned existing methods.

[0005] To achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A construction method for a caisson translation skateboard device, characterized in that: a caisson translation skateboard device is penetrated under the caisson bottom plate, a balance beam is connected by a winch steel wire rope, and the support beam and the caisson above it are driven to slide forward along the track beam. After the caisson moves forward a certain distance, the track beam section and the limit rod behind the caisson are removed and transported to the front of the caisson to extend the track beam until the caisson is transported to the designated position. The construction method specifically includes the following steps:

[0007] S1: Bond the skateboard; bond the lower skateboard on the top surface of the track beam, bond the upper skateboards on the bottom surfaces of the support beam and the balance beam respectively, and fix them between the baffles, 5-10 mm higher than the baffles, and slide along the lower skateboard;

[0008] S2: Jack up the caisson; use a jack or an airbag to jack up the caisson, and the jacking height is greater than the standard section of the support beam and the track beam including the lower skateboard and the upper skateboard, 3-5 cm higher;

[0009] S3: Lay the track beams and the limiting rods; longitudinally connect the track beam segments, connect the connecting plates between two segments by bolts, and the longitudinal length is greater than the length after the connection of the support beam and the balance beam; respectively pull the longitudinally connected track beam segments to the bottom of the caisson, and arrange limiting rods between the front and rear track beams of the caisson. The rectangular inserting plates of the limiting rods are respectively inserted into the rectangular jacking holes at the positions of the lower flange plates between the two track beams.

[0010] S4: Insert the support beam and the balance beam; respectively insert the support beam and the balance beam into the upper flange plates of the track beams along the limiting plates, pull the support beam along the track beam to directly below the caisson, and connect the towing lugs of the support beam and the towing lugs of the balance beam by inserting pins through rigid pull rods.

[0011] S5: Lower the caisson; lower the caisson by operating the jacks or air bags and place it on the top surface of the support beam.

[0012] S6: Extend the track beam; longitudinally extend the track beam segments, connect the connecting plates between two segments by bolts, and the total longitudinal length is greater than twice the length after the connection of the support beam and the balance beam. The front end is inserted into the limiting rod.

[0013] S7: Winch traction; connect the winch steel wire rope to the towing lug on the front side of the balance beam, start the winch to drive the balance beam, the support beam and the upper caisson thereon to slide forward along the track beam.

[0014] S8: Transfer the track beam and the limiting rod; move the caisson forward, stop the traction when the balance beam reaches near the front end of the track beam, remove the track beam and the limiting rod behind the caisson and transfer them to the front of the caisson.

[0015] S9: Completion of caisson translation; repeat steps S6 - S8 until the caisson is transported to the designated position and the translation is completed; lift the caisson by using jacks or air bags, or hoist the caisson by a crane ship, and then remove the caisson translation sliding plate device for reuse.

[0016] In the step S1, the lower sliding plate is a 2 - cm - thick polytetrafluoroethylene (PTFE) plate, which is bonded to the top surface of the track beam by epoxy glue, and silicone grease is evenly applied thereon to reduce the friction coefficient between the PTFE plates; the upper sliding plate is a 2 - cm - thick PTFE plate, which is respectively bonded to the bottom surfaces of the support beam and the balance beam by epoxy glue.

[0017] In the steps S1 - S4, S6 - S8, the track beam is a double - web steel structure, with a single - section length of 4 - 6 m, and connecting plates are welded and fixed at both ends. A set of rectangular jacks are arranged at equal distances from both ends, and each set of jacks is respectively arranged on the lower flange plates on both sides of the track beam; the track beam is arranged in longitudinal sections, and the connecting plates between two sections are connected by bolts; the width of the track beam can be calculated according to the self - weight of the caisson and the designed compressive strength of the sliding plate to ensure that the load - bearing safety factor of the sliding plate meets the requirements.

[0018] In steps S3, S6, and S8, the limiting rod is a square steel pipe structure, with rectangular insertion plates welded and fixed at both ends, which are respectively inserted into the rectangular jack holes in the lower flange plates between two track beams; the longitudinal spacing of the limiting rods is 4 - 12 m to ensure that the distance between the track beams remains unchanged.

[0019] In steps S1 - S7, the support beam is a double-web steel structure, with baffles and towing lugs welded and fixed on the outer sides of both ends. The baffle ensures the fixed position when the upper sliding plate slides, and the support beam moves along the track beam through the towing lugs; rib plates and bolt-fixed limiting plates are welded and fixed on both sides of the support beam. The rib plates improve the load-bearing capacity of the support beam. The longitudinal spacing of the limiting plates is not greater than 1 / 2 of the length of the lower sliding plate segment to ensure that each segment of the lower sliding plate is limited by two limiting plates. The gap between the limiting plates 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, is 5 mm to ensure that the support beam and the lower sliding plate do not shift laterally on the track beam; the length of the support beam is greater than the width of the bottom plate in the advancing direction of the caisson.

[0020] In steps S1, S3, S4, S6 - S8, the balance beam is a double-web steel structure, with both ends corresponding to the positions of each track beam. Baffles and towing lugs are welded and fixed on both sides respectively. A pair of limiting plates are bolt-fixed on its lower flange plate. The baffles on both sides ensure the fixed position when the upper sliding plate slides. The towing lugs on both sides are respectively connected to the support beam and the hoist wire rope. The gap between the limiting plates 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, is 5 mm to ensure that the balance beam does not shift laterally on the track beam.

[0021] In step S4, the rigid tie rod is a steel structure, corresponding to the position of each track beam, and is respectively connected to the towing lug of the support beam and the towing lug of the balance beam through pin shafts.

[0022] In step S7, the hoist towing speed of the caisson does not exceed 1 m / min.

[0023] A caisson translation slide plate device adopted by the above construction method, characterized in that: it includes two track beams laid on a flat site and a slide plate mechanism connected to the track beams. A limiting rod for maintaining the distance is connected between the track beams. The slide plate mechanism includes a support beam, a balance beam, an upper slide plate, and a lower slide plate. The lower slide plate is connected to the top surface of the track beam. The support beam is parallel to the track beam, connected to the top surface of the lower slide plate, used to carry the caisson, and its top surface is in direct contact with the outer wall or partition floor of the caisson. The balance beam is located in front of the support beam, perpendicular to the track beam, with both ends respectively connected to the top surface of the lower slide plate, connected to the support beam through a rigid tie rod on one side, and connected to the hoist wire rope on the other side. The upper slide plate is respectively connected to the bottom surfaces of the support beam and the balance beam, and the limiting part penetrates into the upper flange plate of the track beam and slides along the lower slide plate.

[0024] Using the construction method of the present invention, the hoist wire rope is connected to the balance beam, driving the support beam and the caisson above it to slide forward along the track beam, ensuring that the support beams on each track beam move forward synchronously without lateral movement. After the caisson moves forward a certain distance, the track beam segments and limit rods behind the caisson can be removed and transported to the front of the caisson to extend the track beam until the caisson is transported to the designated position. The recycling of the track beam segments and limit rods can be realized for the shipment of a single caisson. Generally speaking, the construction operation is convenient. Regardless of the width of the caisson, by setting the width of the track beam, the force safety and center of gravity stability of the caisson can be ensured. At the same time, all components on the translation skateboard device of the caisson can be recycled, saving materials and reducing construction costs. BRIEF DESCRIPTION OF THE DRAWINGS

Pull the longitudinally connected segments of the track beam into the bottom of the caisson 8 respectively. Set the limit rod 2 between the front and rear track beams 1 of the caisson. The rectangular insertion plates 201 of the limit rod 2 are respectively inserted into the rectangular jack holes 102 of the lower flange plates between the two track beams.

[0036] S4: Insert the support beam 3 and the balance beam 4. Insert the support beam 3 and the balance beam 4 into the upper flange plate of the track beam 1 along the support beam limit plate 304 and the balance beam limit plate 403 respectively. Pull the support beam 3 along the track beam 1 into the position directly below the caisson 8. Connect the support beam towing ear plate 302 and the balance beam towing ear plate 402 by inserting a pin through the rigid pull rod 5.

[0037] S5: Lower the caisson 8. Lower the caisson 8 by operating the jack or the airbag and place it on the top surface of the support beam 3.

[0038] S6: Extend the track beam 1. The track beam 1 is longitudinally extended in segments. Connect the connecting plates 101 between two segments by bolts to ensure that the total longitudinal length is greater than twice the length after the connection of the support beam 3 and the balance beam 4. The front end should be inserted into the limit rod 2.

[0039] S7: Winch traction. Connect the winch steel wire rope 9 to the front-side towing ear plate 402 of the balance beam. Start the winch to drive the balance beam 4, the support beam 3 and the upper caisson 8 on it to slide forward along the track beam 1.

Rib plates 303 are welded on both sides and limit support beam limit plates 304 are fixed by bolts. The rib plates can improve the bearing capacity of the support beam 3. The longitudinal spacing of the limit plates should not be greater than 1 / 2 of the length of the lower slide plate 6 section to ensure that each section of the lower slide plate 6 has two limit plates for limiting. The gap between the support beam limit plate 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 5 mm to ensure that the support beam 3 and the lower slide 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 advancing direction of the caisson.

[0046] In the steps S1, S3, S4, S6 to S8, the balance beam 4 is a double-web steel structure, and both ends correspond to the position of each track beam 1. Balance beam baffles 401 and balance beam traction lugs 402 are welded on both sides respectively. A pair of balance beam limit plates 403 are fixed by bolts on the lower flange plate. The baffles on both sides ensure that the position of the upper slide plate 7 is fixed during sliding.
