摘要：PURPOSE:To reduce the cost of construction work for an undergroundstructure by a method in which cement mortar is injected between the bottom of thelower end box and the concrete bottom slab, a box structure is set, and underwaterconcrete is placed between the box structure and a sheathing wall. CONSTITUTION:Soiland sand in a sheathing wall 1 constructed under the ground is excavated, underwaterconcrete (g) is placed on the bottom of an excavated hole 2 to form a concrete bottomslab 3, and a lower end box (a) is set with space in the excavated hole 2. Water is suppliedinto the lower box (a), and while holding it at a given level, an upper box structureconsisting of underground beams (c), pillars (e), etc., is orderly connected to the upsideof the lower end box (a) to make up a box structure A, and the box structure A is settledto the bottom of the excavated hole 2. Cement mortar (f) is injected between the bottomof the lower end box (a) and the concrete bottom slab 3 to fix the box structure A, andunderwater concrete (g) is placed between the box structure A and the sheathing wall 1.
