Description

Technical Field

[0001] The utility model belongs to the technical field of the construction of cross beams of high-pile wharves, and particularly relates to a trolley for demolishing the bottom formwork support system of the lower cross beam of a high-pile wharf. Background Technique

[0002] PHC pipe piles or steel pipe piles are generally used as the foundation for high-pile wharves, and the lower cross beam is cast in situ on the upper part. The cast-in-situ lower cross beam generally adopts a hoop and I-beam bottom formwork support system. In the prior art, the demolition methods of the bottom formwork support system include the direct demolition method, the hand-pulled hoist suspension support system method, and the hydraulic jack method.

[0003] In the direct demolition method, the operator rides in a special hanging basket, and the hanging basket is hoisted by a crane as a construction operation platform. Holes are drilled on the hoop, and the steel wire rope passes through the holes to fix the hoop on the embedded channel steel at the top of the lower cross beam. Then, the two rows of bolts at the bottom are loosened to make the bottom formwork support system sink a certain distance, and then a floating crane ship is used to cooperate with the operator to demolish the square wood secondary beam and the I-beam main beam. The hand-pulled hoist suspension support system method is to connect the hand-pulled hoist with the steel wire rope. The steel wire rope is slung under the bottom of the main beam I-beam, and a steel wire rope is arranged between two PHC pipe piles. The operator rides in a special hanging basket, and the hanging basket is hoisted by a crane as a construction operation platform. Holes are drilled on the steel hoop, and the steel wire rope passes through the holes to fix the hoop on the embedded channel steel at the top of the lower cross beam. Then, the hoop is removed, and then a floating crane ship is used to cooperate with the operator to demolish the square wood secondary beam and the I-beam main beam. The hydraulic jack method is to first install a steel hoop on the PHC pipe pile, and a hydraulic jack is fixed on the bracket of the steel hoop. After the concrete strength reaches the condition for demolishing the bottom formwork, the jacks are depressurized synchronously to make the bottom formwork support system sink a certain distance, and then a floating crane ship is used to cooperate with the operator to demolish the square wood secondary beam and the I-beam main beam.

[0004] The demolition methods of the bottom formwork support system in the prior art all require the operator to ride in a special hanging basket and use a crane to hoist the hanging basket as a construction operation platform, with extremely high safety risks, low construction efficiency, and the hydraulic jack method cannot be applied to the inclined pile foundation.
