“Two walls in one” is the enclosure wall as a structural wall or part of the structural wall, reasonable use of the enclosure wall, reduce the cost, is the embodiment of green construction
. 
In the integral “two walls in one”, about 300 composite walls (lining walls) are set inside the diaphragm wall, and the groundwater is sealed outside by the two walls
. 
Separate “two walls in one”, set pilaster at the joint of diaphragm wall, set brick or concrete isolation lining wall between pilaster, adopt “Dredging” method for waterproof, set drainage ditch between diaphragm wall and lining wall, if there is leakage, water will be discharged from drainage ditch

a) The connection between diaphragm wall and bottom (floor) the connection between diaphragm wall and bottom (floor) the connection between diaphragm wall and bottom (floor) the connection between diaphragm wall and bottom (floor) the connection between diaphragm wall and bottom (floor) the connection between diaphragm wall and bottom (floor) the support of temporary enclosure wall and floor in the reverse operation of horizontal structure is replaced by floor, so the space between enclosure wall and horizontal floor needs to be shaped To form a reliable support system to ensure that it transmits the horizontal force of the retaining wall
. 
Generally, it is transferred by force transfer steel
.
There are two problems to be considered in the connection of temporary retaining wall and floor slab: first, the permanent column is not formed, and the floor beam (slab) is placed on the lattice column, so the vertical force transmission at the joint should be considered, and the shear structural reinforcement, stud or steel bracket should be set on the lattice column; second, the lattice column steel plate affects the direct connection of the beam longitudinal reinforcement, and the horizontal haunching can be added at the beam joint

.
When the design is “one column with multiple piles”, the arrangement of piles should be adjusted as far as possible so that there are piles under the column, so as to set up steel columns
.
The bearing capacity of column piles during construction should be checked
.
If there is no pile under the column, it is necessary to use multiple steel columns and joists on the top of the column to transfer the load, increase the resource consumption and increase the construction difficulty
