Minimum constructive height is that its lower end is inserted into soil layer 0.5~1.5m the distance between to ground；Simultaneously according to construction frame structure main body
Sectional dimension determines the size of steel sheet pile supporting (6), and the size of steel sheet pile supporting (6) is every side of construction frame structure main body
Outer is to 1~1.5m of external expansion；
2) one group of leading truck is installed according to the steel sheet pile supporting (6) of above-mentioned determination, this group of leading truck is simply possible to use in one piece of second drawing
The installation of gloomy steel sheet pile；
3) first piece of the second Larsen steel sheet pile is squeezed into soil layer to desired depth in leading truck, squeeze into successively afterwards remaining second
Larsen steel sheet pile is extremely identical with the depth of first block of the second Larsen steel plate and is enclosed, afterwards first by first piece of the second Larsen steel sheet pile
Squeeze into projected depth, then remaining second Larsen steel sheet pile is squeezed into projected depth form steel sheet pile supporting (6) successively, in advance
Depthkeeping degree is away from soil layer surface 2-3m；
4）Multiple auxiliary shoring components (7) are installed in steel sheet pile supporting (6) outside：Polylith the second Larsen steel sheet pile is squeezed into successively connected
Form auxiliary shoring component (7), the second Larsen steel sheet pile of auxiliary shoring component (7) one end and in steel sheet pile supporting (6) second
Connecting hook two (41) hook of Larsen steel plate connects, and the vertical steel sheet pile supporting (6) of auxiliary shoring component (7)；
5) above-mentioned leading truck is removed.
