Technical Field
The invention belongs to the technical field of building equipment, and particularly relates to a shed tunnel construction supporting structure.
Background
The shed tunnel is a tunnel which belongs to the open cut tunnel category, wherein a simple ceiling frame is constructed after the cut is dug in the open cut, and a tunnel body is formed by backfilling. The condition of adopting the shed tunnel is similar to that of the open cut tunnel, the structural integrity of the shed tunnel is poorer than that of the open cut tunnel, but the requirement on the foundation is relatively lower because the ceiling and the inner and outer walls are simply supported. The hangar tunnel has various types according to different terrain and geological conditions, but is basically constructed with an inner wall, an outer side supporting structure and a roof supporting structure. Under the condition of weak foundation conditions, a bottom supporting structure is required to be arranged, which is equivalent to a supporting beam of the culvert. Two methods are generally adopted for the shed tunnel formwork: firstly, the investment cost is high due to the adoption of the improvement of a tunnel trolley; secondly, the full hall support supports the template, and this mode dismouting is troublesome. Need set up to cambered surface structure in shed tunnel top corner in the shed tunnel work progress to increase the support stability at shed tunnel top, current shed tunnel bearing structure, during the drawing of patterns, mould and shed tunnel relative friction cause the drawing of patterns difficulty.
