Description

TECHNICAL FIELD

[0002] In the tunnel excavation construction, especially in the condition that the geological surrounding rock is poor, the design often adopts the steel arch support to complete the initial support. The steel arch is generally processed and manufactured by the I-shaped steel at the construction site, and is formed by connecting the steel plates with a certain thickness as connecting plates between the ends of each section after the steel arch is processed into several sections according to the arc radius of the tunnel contour size.

[0003] However, in the process of installing the steel arch for initial support in the tunnel excavation, problems such as uneven steel frame, misaligned holes, and non-tight connection of the connecting plate after installation often occur. These problems not only lead to the decline of construction quality, but also increase the time and labor intensity of construction operation, and improve the safety risk. In the process of welding the connecting plate of the large steel arch, the steel arch has a large volume and weight, and can only be placed flat. The connecting plate can be welded after being attached to the end. However, in this process, there is a lack of reliable fixing structure between the connecting plate and the steel arch, and the connecting plate is easy to slide during welding operation. This can cause large gaps in the welding position, the connecting plate is easy to deviate, and further cause problems such as unstable welding, non-corresponding bolt hole position, and ineffective connection between connecting plates. These problems not only have great difficulty in rework processing, but also seriously affect the construction quality. In addition, the traditional direct welding method of the connecting plate has many deficiencies. For example, the connecting plate is not accurately positioned, the connecting plate cannot be smoothly connected during on-site construction; there is a lack of reliable fixing structure, the connecting plate is easy to slide during welding operation; and there is a lack of accurate positioning device, which leads to low construction efficiency and serious material waste.
