Description

Tunnel is showy supporting construction that buries of highway down

Technical Field

The utility model relates to a shallow technical field that buries in tunnel specifically is a tunnel is worn highway under and is shallowly buried supporting construction.

Background

The tunnel is a huge branch system on the highway engineering. According to the investigation of construction data of a large number of tunnel projects, a tunnel or a section with an upper covering layer which is 2 times as short as a tunnel hole is a shallow buried tunnel, and meanwhile, the excavation construction of a shallow buried section project and a hole reinforcing section is carried out by selecting an excavation method and a supporting mode according to the factors of geological conditions, the influence of surface deep subsidence on ground buildings, construction safety guarantee and the like. Shallow tunnel burial means that the tunnel section with the upper covering layer of the tunnel, which is 2 times less than the tunnel hole, belongs to the shallow tunnel burial section. The tunnel is a structure built for passing through mountains when roads or railways are obstructed by mountains, and generally comprises a main structure and auxiliary structures, wherein the main structure comprises a hole door and a hole body lining, and the auxiliary structures mainly comprise systems for tunnel water supply and drainage, ventilation, illumination, power supply and the like. The excavation construction and the support are carried out in a shallow-buried and opening reinforced section, the excavation construction and the support are selected according to the geological conditions, the influence of surface subsidence on ground buildings, the construction safety guarantee and other factors, the construction effect and the engineering cost are considered, the tunnel shallow-buried section and the opening reinforced section are determined and are usually positioned in surrounding rocks with weak, broken and extremely short self-stabilizing time, if the construction method and the support mode are improper, roof collapse or harmful subsidence of the surface is easy to happen, and the safety of the building is endangered when the building exists on the surface. Therefore, measures such as supporting and then excavating or sub-excavating should be adopted to prevent instability caused by excavating work or harmful subsidence of the ground surface.

The existing tunnel underpass highway shallow-buried supporting structure product has the following defects:

1. when the tunnel is supported, the highway subgrade cannot be effectively supported, and a bidirectional supporting structure is lacked;

2. concrete pouring is not convenient enough, and a stable maintaining structure is lacked after pouring.
