Description

Slipform workbench with concrete distributor The present invention relates to a slipform workbench equipped with a concrete distributor, and more specifically, to a slipform workbench equipped with a concrete distributor that is installed inside a vertical shaft and allows for the continuous construction of a vertical shaft structure while being raised. Recently, as the development of deep-level urban transportation facilities progresses, the importance of vertical shaft structures is being emphasized. These vertical shaft structures are being utilized not only as station shafts and vertical ventilation shafts in deep underground road and railway tunnels, but also as spaces for installing evacuation stairs and elevators, as well as ventilation facilities and electrical and communication facilities. Furthermore, for vertical shaft structures for railways, roads, and power conduits currently being constructed mostly in urban areas, minimizing public complaints arising from the opening of transportation facilities is considered paramount, prioritizing accident-free construction methods and shortened construction periods. Accordingly, while various construction methods have been developed and are being used to construct vertical shaft structures, the slipform method is being used, which can ensure effective construction time reduction, cost reduction, quality, and stability. The slipform method is a method of continuously constructing vertical shaft structures by continuously raising the slipform, and it can shorten the construction period by more than twofold compared to the existing on-site casting method, which involves repeatedly installing and removing formwork and shoring. In other words, while the cast-in-place method has the problem of a prolonged construction period due to the repeated installation and removal of formwork and shoring for each floor, the slipform method has the advantage of increasing work process efficiency by requiring only one slipform installation and removal operation inside the vertical shaft, as well as significantly reducing the rate of safety accidents by using a slipform composed of upper, middle, and lower work platforms. In the case of the slipform method described above, a concrete hopper is generally installed on an upper work platform, and a concrete injection pipe is connected to the bottom of the hopper at a downward angle. As the slipform work platform is raised, concrete is injected through the hopper and the injection pipe to continuously pour circular and vertical walls, thereby constructing a vertical shaft structure. However, recently, as the diameter of vertical shaft structures increases, there is a problem in that there are limitations to improving work speed with the method of installing a concrete hopper as described above and injecting unhardened concrete for pouring.
