Description

Technical Field

[0001] The utility model relates to the field of tunnel excavation bench construction, and more specifically, to a simple excavation bench construction device for a small-section tunnel. Background Art

[0002] In the process of tunnel construction, the work trolley is an indispensable construction machinery device. In the past, most of the work trolleys were only suitable for large-section tunnels such as highways and railways. They have a large working surface and sufficient working space, and can be constructed with large mechanical equipment, but cannot be used for small-section tunnel construction. The construction process of small-section tunnels is multi-crossed and interferes with each other. Drilling, blasting, slag removal and other work on the same working surface can only be carried out periodically, and it is easy to affect the layout of pipelines in the tunnel. Therefore, we need to design a new simple excavation rig construction device for small-section tunnels. Utility Model Content

[0003] In order to achieve these purposes and other advantages according to the utility model, a preferred embodiment of the utility model provides a small-section tunnel simple excavation bench construction device, comprising:

[0004] The stand is a door-shaped structure;

[0005] There are two side wings, which are horizontally connected to the two outer sides of the platform respectively, and a diagonal brace is arranged below the side wing. The diagonal brace is arranged obliquely, with one end connected to the side wing and the other end connected to the outer side of the platform;
