摘要： PROBLEM TO BE SOLVED: To provide an injection method capable of extremely easily performing the opening and closing processing of a passage between a drilling process and a chemical injection process even when a ground injection chemical is of a type not solidified in its single use but solidified when mixed, and an injection device used for the method. SOLUTION: This method includes a drilling process for injecting an excavation fluid from an exhaust nozzle 6 communicating with the excavating fluid passage 20 of the injection device 1 provided at the tip end of an excavating rod 2; and an inserting process for inserting a chemical injection unit 9 to the injection device. In the inserting process, the tip end part 40 of the chemical unit 9 opens an ordinarily closed opening and closing means 8 interposed in the injection chemical passage 30 of the injection device 1 and closes a drilling fluid passage 20. This method further includes a process for expanding a packer 13 installed to the chemical injection unit 9 and a process for injecting the injection chemical. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To provide an excavation method executable even in the presence of a building on the ground side of an injection material injection region in the ground, requiring to bore only one guide excavated hole within the same construction plane without needing to move an excavator for every borehole. SOLUTION: This excavation method comprises a boring process for boring excavated holes 4, 4B in a prescribed injection material injection region 2 by a boring rod 11 using a universal boring machine 1, and an injection process for injecting the injection material 6 from a boring rod tip 11a while pulling the boring rod 11 back. The injection process comprises a branch excavated hole boring process for interrupting the pull-out of the boring rod at branch points Y1-Y5 in the injection material injection region 2 without pulling the boring rod 11 completely out of the excavated holes 4, 4B, and boring branch excavated holes 51-55 separately in the injection material injection region 2 from the branch points Y1-Y5.

摘要： PURPOSE:To secure face-contact between slide parts by a method in which a pressure-bearing metal consisting of a pair of slide members to be mutually combined with each other at their horizontally and vertically curved faces is attached to the bottom plate of two floating caissons, and the two floating caissons are contacted with each other through the pressure-bearing metal. CONSTITUTION:In the slide member 8 of a pressure-bearing metal 3, one end is attached to the contact face of the bottom plate 4 of a floating caisson 1, the other end is shaped into a circular recession extended horizontally, and a circular recession is also formed in the vertical direction. In a slide part 9, a projection to be matched with the vertical and horizontal circular recessions of the slide member 8 is formed. Both the members 8 and 9 are set by matching their recession and projection with a slight spacing, and the member 9 is temporarily coupled by a shear bolt 13 from a slide plate 10 attached with a bolt 11 to both sides of the part 8. The other end of the member 9 is faced almost in parallel with the end face of the pressure-bearing metal 3' of the counter floating caisson 4'. The face-contact of both the members 8 and 9 can thus be secured by relative sliding to eliminate the local concentration of stress.

摘要： PROBLEM TO BE SOLVED: To provide a filling method in which a flow passage opening/closing treatment is extremely easily performed between a drilling step and a chemical filling step even if a ground-filled chemical is a type that is not solidified solely but solidified when it is mixed with the other and a filling device used for the method.
SOLUTION: This filling method comprises the drilling step of jetting a fluid for excavation from a nozzle 6 communicating with a fluid flow passage 20 for excavation of the filling device 1 attached to the end of an excavation rod 2, and the insertion step of inserting a chemical filling unit 9 into the filling device. In the insertion step, the end 40 of the chemical filling unit 9 opens a normally closed open/close means 8 installed in the flow passage 30 for filling chemical of the filling device 1 and closes the fluid flow passage 20 for drilling. The method further comprises the step of expanding a packer 13 fitted to the chemical filling unit 9, and the step of jetting the filled chemical.
