Problems solved by technology

The traditional construction method is to use steel formwork trolleys with high economic costs or full-scale scaffolding construction methods with high operating costs. However, due to the fact that the similar size of tunnel engineering structures is especially rare, it is difficult for special steel formwork trolleys to continue to be used in other projects. The cost of transfer and transformation of mold trolleys is extremely high, the secondary utilization rate is extremely low, and the cost performance is relatively low in the construction of underground caverns with medium and small diameters

Abstract

The invention discloses a simple steel mould trolley which is mainly composed of a running wheel, a platform, a load bearing scaffold, a lagging jack and a moldboard, wherein the platform is arranged on the running wheel, the load bearing scaffold is arranged on the platform, and the lagging jack is an arc-like structure frame made of a steel pipe; the lagging jack is composed of a top arch and two side arches, the side arches are articulated with the top arch, and the moldboard is composed of a side module and a top module; and the lagging jack of the top module is placed above the load bearing scaffold, the lagging jacks of the side arches are placed on the two sides of the load bearing scaffold, and the side module and the top module are fixed on the lagging jack. Compared with the traditional steel mould trolley, the manufacturing cost is low, the performance is high, the operation is simple and convenient, the installation is rapid, the processing and manufacturing material can be totally utilized and recycled basically, the construction process is simple, and the building workers can master the simple steel mould trolley conveniently.

Description

technical field [0001] The invention belongs to the technical field of water conservancy and hydropower (underground) engineering, and in particular relates to a simple steel mold trolley. Background technique [0002] In the construction of water conservancy and hydropower (underground) projects, the selection of formwork is particularly important during tunnel concrete lining construction. The selection of formwork has a huge impact on project duration, project cost, and project construction cost. The traditional construction method is to use steel formwork trolleys with high economic costs or full-scale scaffolding construction methods with high operating costs. However, due to the fact that the similar size of tunnel engineering structures is especially rare, it is difficult for special steel formwork trolleys to continue to be used in other projects. The cost of transfer and transformation of mold trolleys is extremely high, and the secondary utilization rate is extreme...
