Dynamic, digging pine, and mud is filled in the gap between cambered surface concrete slab and the soil body, make precast concrete basil component because certainly
Weight, sink naturally；
F, stop loosening the soil to after specifying absolute altitude after the prefabricated basil component entire lowering of annular；
G. hoisting prefabricated concrete guard wall component, installation, splice at the top of precast concrete basil component, notice that the fissure of displacement is spelled
Connect, be assembled into the annular enclosed a prefabricated components；
H. c, d, e, f steps are repeated, until precast concrete basil component sinks down into final designed elevation, cylindrical underground
Space structure is formed.
The angle steel basil sheath, it is in order to encase the concrete basil, to protect concrete basil part will not be by the soil body
Or the rock failure mechanism of rock.
The circular hole being distributed on the concrete floor, it is the connection for transverse steel.
The lateral arcs surface concrete plate, surface should be accomplished enough smoothly to reduce to the frictional force of the soil body, can also be
The attached last layer stalloy in outer surface is rubbed with reducing.
Beneficial effects of the present invention：
1st, the present invention can improve a rate of advance of the underground space；
2nd, the present invention removes the process of slope retaining from；
3rd, the present invention can reduce manual work, reduce Contraction in Site；
4th, the invention enables job site noise is small, pollution is small；
5th, the present invention realizes factorial praluction, convenient and swift.
