A construction method for the overall transfer of large steel formwork trolleys in the adjacent field

Abstract

A construction method for the overall transfer of large-scale steel molds between adjacent sites. Through the analysis of the weight, size, and road conditions of the steel mold trolleys hoisted and transported, the walking track frame and lifting of the steel mold trolleys are reasonably designed. Spreaders, hauling and fixed frames, etc., are reasonably matched with mechanical equipment such as hoisting and transshipment, and adopt the method of "rail frame outlet pipe section cavity + large-tonnage crawler crane overall hoisting + heavy-duty low-bed semi-trailer trailer hauling", divided into sections Complete the overall transfer construction of the large steel formwork trolley. The design of the rail frame, hanger, and load-bearing beam bracket used in the present invention is reasonable, which is convenient for installation and removal on the construction site, reasonable allocation of lifting and transportation equipment, planning of hoisting and transportation routes in advance, ensuring the integrity of the steel mold trolley, and effectively connecting the processes to form Assembly line operation greatly reduces worker load, less interference factors, fast transition speed, meets construction schedule requirements, guarantees safe and civilized construction, and is suitable for large-scale promotion and application.

Description

technical field [0001] The invention relates to a construction method for the overall transfer of large-scale steel formwork trolleys between adjacent fields, and belongs to the technical field of steel formwork trolley transition construction. Background technique [0002] At present, in the prefabrication construction of immersed tube sections, the dry dock is mainly used as the prefabricated site. The dry dock needs to go through complex working conditions such as excavation, prefabrication, water filling, outfitting, dock opening demolition, restoration, and backfilling. The project cost is high, the anti-seepage system requirements are strict, and the construction period is greatly affected. At the same time, it is restricted by navigation, hydrology and other conditions. The quantity is large, and it needs to be prefabricated, floated, sunk and docked in batches. [0003] In large-scale reinforced concrete construction, the selection and application of the formwork sy...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problems existing in the prior art, and provide a construction method for the overall transfer of large steel formwork trolleys in the adjacent field, so that the large steel formwork trolleys enter and exit the pipe section cavity, hoisting, and transfer. Sequential connection forms a flow operation, which effectively reduces the scope and frequency of disassembly and assembly of steel formwork trolleys, and solves the impact of large-scale steel formwork trolleys on the rigidity and integrity of steel formwork trolleys due to disassembly, transfer, and reverse transportation. The construction progress is significantly accelerated, and the safety Guaranteed quality and significant economic benefits
