Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of building construction, in particular to a high -speed railway box girder retaining wall construction device. BACKGROUND
[0002] The high-speed railway three walls arranged at the top of the high-speed railway box girder are important components of the box girder in high-speed railway construction and play an important role in the safety of high-speed train operation. The high-speed railway three walls mainly include A wall, B wall (also called vertical wall) and protective wall (also called ballast retaining wall). At present, the three walls at the top of the high-speed railway box girder are mostly cast in situ, that is, the concrete is poured after supporting with steel formwork, the formwork is removed and transferred for reinstallation and support, the number of steel formwork required and the number of steel formwork turnover are relatively large, the time period for on-site removal and transfer of support is long, the number of workers for manual installation and transfer of formwork is large, and the labor intensity is high. Before the construction of the high-speed railway three walls is completed, the box girder is orderly placed in the construction site, and the steel formwork and construction equipment need to be transported between different box girders, the height of the top surface of the box girder from the ground is high, and the transportation is very inconvenient. The equipment used for the construction of the three walls includes concrete tank trucks (used for providing concrete), handling equipment (used for handling steel formwork on the top surface of the box girder or the ground) and cranes (used for lifting the box girder on the handling equipment, steel formwork and the like, and pouring and distributing materials through the crane hopper). Pump trucks can also be used in cooperation with concrete tank trucks for pouring, but the use cost of the pump trucks is too high, and the pump trucks are more suitable for large-area pouring, which is not conducive to pouring and construction in the narrow and long three-wall cavity. The use of pump trucks for the construction of the three walls not only has high cost, but also has relatively low efficiency. The pouring and distribution of materials through the crane hopper occupies the crane for a long time, and multiple people are needed to operate the hopper end to accurately pour and irrigate during the construction of the crane hopper, which is low in efficiency and poor in safety.
