Example is not intended to limit the scope of the invention for illustrating the present invention.
A kind of shallow buried covered excavation Urban Underground pipe gallery non-stand construction method is present embodiments provided, including is walked as follows
It is rapid:
Step 1, small pilot tunnel quantity and the position of step excavation are determined according to the cabin quantity of piping lane design and position.Example
Such as, double cabin piping lanes use two small pilot drives, and three cabin piping lanes use three small pilot drives, the boundary of each small pilot tunnel and pipe
Mid-board after the completion of corridor is overlapped.
Step 2, small pilot tunnel applies preliminary bracing after the completion of excavating drilling depth every time, and is excavating boundary and vertical mid-board weight
Permanent vertical bracing members are set at conjunction, form vertical temporary construction bracket, will permanently vertical bracing members upper and lower ends respectively with it is small
Grid steel frame or steel arch-shelf connection in pilot tunnel preliminary bracing, to undertake construction loads.
Step 3, secondary lining is applied after the completion of small pilot tunnel preliminary bracing, according to the permanent vertical steel of design requirement additional configurations
Support, will setting spiral net between adjacent permanent vertical bracing members, and by spiral net and permanent vertical steel support phase
Connection pours mid-board concrete (without removing bracing members) using permanent vertical bracing members as skeleton, forms armored concrete
Mid-board, and then Pipe rack is formed with preliminary bracing, secondary lining.
By the shallow buried covered excavation Urban Underground pipe gallery non-stand construction method, guaranteeing the same of piping lane excavation safety
When, it is entirely avoided the same of engineering material is being saved in the work such as installation, dismounting and outward transport of falsework in existing construction method
When reduce labour cost, and shorten excavate circulation time, accelerate construction speed.
In the present embodiment, the quantity of permanent vertical bracing members (every circulation of excavating is set up) is true according to the size of vertical load
It is fixed.
In the present embodiment, permanent vertical bracing members use H profile steel or double angle.
