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 the treatment cost of the prefabrication site is relatively low. However, 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 plate 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, and the friction between the caisson and the limit block needs to be overcome during deviation correction. After the caisson moves again after deviation correction, 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 adjustment in this way affects the traction translation speed of the caisson. In addition, the limit is made of precast blocks, and the size is also large, which is inconvenient for construction operation and has a 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 in view of the technical problems existing in the above-mentioned existing methods.

[0005] To achieve the above purpose, the present invention adopts the following technical solutions: 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, 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: 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; 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; 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 insertion plates of the limiting rods are respectively inserted into the rectangular jack holes at the lower flange plates between the two track beams. S4: Pass through the support beam and the balance beam; respectively pass the support beam and the balance beam through 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 passing rigid pull rods through the pin shafts. 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. 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. 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 to slide forward along the track beam. 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. S9: The translation of the caisson is completed; 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 lift the caisson by a crane ship, and then remove the caisson translation skateboard device for reuse.

[0006] In the step S1, the lower slide plate is a 2 - cm - thick tetrafluoroethylene plate, which is bonded to the top surface of the track beam by epoxy glue, and silicone grease is evenly applied on it to reduce the friction coefficient between the tetrafluoroethylene plates; the upper slide plate is a 2 - cm - thick tetrafluoroethylene plate, which is respectively bonded to the bottom surfaces of the support beam and the balance beam by epoxy glue.

[0007] 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. Connecting plates are welded and fixed at both ends, and a set of rectangular jacks are arranged at equal distances from both ends. 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 skateboard to ensure that the safety factor of the skateboard load - bearing meets the requirements.

[0008] In the steps S3, S6, 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 at the lower flange plates between the 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.

[0009] In the steps S1 to S7, the support beam is a double-web steel structure. Fixed baffles and towing lugs are welded to the outer sides of both ends of the support beam. The baffles ensure the fixed position of the upper slide plate during sliding, and the support beam moves along the track beam through the towing lugs. Rib plates and bolt-fixed limit 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 limit plates is not greater than 1 / 2 of the length of the lower slide plate segment, ensuring that each segment of the lower slide plate is limited by two limit plates. The gap between the limit 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 5 mm, ensuring that the support beam and the lower slide 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.

[0010] In the steps S1, S3, S4, S6 to S8, the balance beam is a double-web steel structure. The two ends respectively correspond to the positions of each track beam. Fixed baffles and towing lugs are welded and fixed on both sides of the balance beam. A pair of limit plates are bolt-fixed on the lower flange plate of the balance beam. The baffles on both sides ensure the fixed position of the upper slide plate during sliding. The towing lugs on both sides are respectively connected to the support beam and the hoist wire rope. The gap between the limit 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 5 mm, ensuring that the balance beam does not shift laterally on the track beam.

[0011] In the 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.

[0012] In the step S7, the hoist towing speed of the caisson does not exceed 1 m / min.

[0013] 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 limit rod for maintaining the spacing 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, and the two ends are respectively connected to the top surface of the lower slide plate. One side is connected to the support beam through a rigid tie rod, and the other side is connected to the hoist wire rope. The upper slide plate is respectively connected to the bottom surfaces of the support beam and the balance beam, and the limit passes through the upper flange plate of the track beam and slides along the lower slide plate.

[0014] 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 the synchronous forward movement of the support beams on each track beam without lateral movement. After the caisson has moved forward a certain distance, the track beam segments and the 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 the limit rods can be realized for the transportation 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 the 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 the construction cost. Brief Description of the Drawings
