摘要： PURPOSE:To make underground excavation work for constructing an underground structure of a building to be built on a gound having high ground-water level or on a weak ground executed by dry work of open-cut without requiring landslide protection frames. CONSTITUTION:Soil improvement 3 is executed by means of deep soil stabilization by chemical method all over an area including an extent from the ground surface 2 of a weak ground 1 to a depth D required for construction of an underground structure 4 and a plane figure of the underground structure 4 with wall thickness H necessary for self-sustaining landslide protection walls 5a added around the structure. An area corresponding to construction of the underground structure 4 in the soil improvement 3 is excavated by dry work of open-cut with a heavy construction machine 8 brought into the construction site. Therefore, no landslide protection frame is required, and a site by pit excavation by a large-scale side slope excavation provides a large space for execution of work in an open space. As the impermeability of the improved soil 3 is high, there is no spring water springing in the pit even in the soil having high ground-water level, and excavation by dry work under dry conditions can be executed.

摘要： PURPOSE:To reduce the cost of construction by a method in which while a high- water absorptive polymer gel is discharged with stirring from a rotary excavating shaft, the excavating shaft is penetrated into sandy ground, and while a solidifying agent is discharged, the shaft is pulled out. CONSTITUTION:An excavating shaft 4 is penetrated into sandy ground while being turned, and a gel 6 prepared by adding a high-water absorptive polymer to water is discharged from the tip 5 of the shaft 4. Whereupon, the gel 6 is mixed with sand to form a column 7. When cement milk 8 is discharged from the tip 5 through a path separated from the gel 6 while drawing out the shaft 4 being turned, the milk 8 is mixed with the gel 6 to form a sol column 9. When the shaft 4 is then pulled up to the ground's surface, a sand pile 10 solidified with cement is formed.

摘要： PROBLEM TO BE SOLVED: To secure integrated strength of mutual wall bodies of a crossing part by agitating/mixing these by injecting a retardant-added stabilizer and delayed effective cement into the crossing part with an improved earth wall of postexecution work when forming an improved earth wall of preexecution work. SOLUTION: When forming a preceding improved earth wall W1, a retardant-added stabilizer or delayed effective cement is injected into a crossing part 10 with an improved earth wall W2 of postexecution work executed thereafter. Thus, the improved earth wall W1 is formed, revelation of strength of the crossing part 10 is restrained for many hours, and execution work of the improved earth wall W2 of postexecution work is advanced before revealing strength of the crossing part 10. The crossing part 10 is executed so as to reveal strength at the almost same time. Thus, even if an excavating mechanism cuts and passes through the improved earth wall W1 of preexecution work at execution work time of the improved earth wall W2 of postexecution work, mutual wall bodies are integrated in the crossing part 10 of the improved earth walls W1, W2 to reveal high strength to thereby easily provide the firmly integrated, highly strong and reliable crossing wall 10.
