伸びている。 Such an underground continuous wall construction method involves, for example, excavating using a multi-axis auger, injecting and stirring a hardening material such as mortar to create a soil mortar wall, and before hardening, use H-shaped steel as a stress material. There is a construction method that involves inserting a pile, which has high water-stopping properties and wall strength, and costs about the same as the sheet pile burial method, so its construction track record is increasing, mainly in urban construction.

Continuous underground walls such as soil cement walls use excavating machines such as auger machines during construction, so as shown in Figs. The distance to the wall 1 is restricted, and therefore the distance D between the outer walls is also determined. The distance D between the outer walls in this case varies somewhat depending on the wall thickness of the underground continuous wall 1 and the cross-sectional dimension of the H-beam 8 as a stress member, but generally
It is about 70-80cm.

ができる。 The erection member 5 is made by connecting webs of parallel H-beams 6 with a partition plate such as a steel plate, and can be manufactured in advance at a factory. The frame side of the construction member 5 is excavated to the position of the partition plate 7, and a pillar type 4 protruding from the outer wall surface of the underground part 2 of the frame is housed. Above ground pillar 10
can be constructed continuously with this, and the outer wall 11 can also be located on the outside accordingly, so the distance D between the outer wall and the adjacent building 9 can be reduced to a columnar type 4. can be reduced by the amount of protrusion.
第３図ａ，ｂ，ｃ，ｄは施工手順の一例を示し
