摘要： PROBLEM TO BE SOLVED: To provide an economical and rational countermeasure construction method against the liquefaction of under ground supporting an existing structure capable of forming a diaphragm wall having a substantially trapezoidal vertical section by designing an injection solidification method for the under ground supporting the existing structure (soft ground such as sandy ground).
SOLUTION: The diaphragm wall 4 having a substantially trapezoidal vertical section the width of which is gradually reduced from a deep layer toward a shallow layer is formed in the under ground 3 supporting the existing structure 1 by repeatedly performing a process for drilling under ground 3 supporting the existing structure 1 at a fixed inclination angle by a boring machine type ground improving machine 2 installed at a position adjacent to the existing structure 1, and forming one or a plurality of ground improving bodies 4a in the axial direction of the drilled part while successively changing the axial angle.

摘要： PROBLEM TO BE SOLVED: To remove/reduce bad influence of so-called lever action force for preventing deterioration in safety of a bolt and lowering a cost so as to provide a bolt coupling for a segment in a shield tunnel allowing economical design. SOLUTION: In bolts, against warping deformation of a coupling plate due to tensile force loaded in the main beam direction between segments mutually, a bolt positioned in the vicinity of the main beam is set to the length exhibiting tensile strength within an allowable range when it is extended equivalent to the warping of deformation of the coupling plate in its position, and this long bolt is fastened by means of a nut while using a cylindrical long washer with a length necessary for the bolt length.

摘要： PURPOSE: To provide a tensile type joining adopted as a joint for a vertical part where a SRC composite segment receives negative bending moment, in which tensile force is met with resistance by the shearing strength of a joining projected part formed on the inside flange and a connecting plate, and the number of bolts to be used will be especially small. CONSTITUTION: A central steel frame material 2 forming a SRC composite segment 1 is disposed on the outside of the neutral line of the segment 1 where to bear tensile force, and a joining projected part 3 is formed in the direction substantially right-angled to the axial direction of the material and inward on the joining end part of the inside flange 2a. The joining projected arts 3 of two adjacent composite segments 1 are butted against each other, and a connecting plate 7 having a recessed part 5 for storing the projected parts substantially closely is applied with two joining projected parts 3 stored in the recessed part 5 extending over both flanges 2a. A bolt 8 passed through a bolt hole 6 of the connecting plate 7 is screwed in a tapped hole 4 of the inside flange 2a and fixed.
