摘要： PROBLEM TO BE SOLVED: To provide a lining member which can sufficiently absorb tail clearances on both longitudinal ends of an existing segment, in a width-enlarging type shield excavator.
SOLUTION: The width-enlarging type shield excavator comprises a main excavator (1) and sub-excavators (2a, 2b) provided on both sides thereof. An axial line of each of the sub-excavators (2a, 2b) is displaced relative to an axial line of the main excavator (1) so that excavation may be conducted while enlarging the width. The lining member (4) used for the width-enlarging type shield excavator comprises a plurality of pieces including at least four corner parts (20a) as in Fig. 4. A bolt fitting hole (20A) for fitting a new segment (20A) to the existing segment (20) of each of the corner parts (20a) is formed to be an arc-like long hole having a center of the segment as the center of the arc-like shape.

摘要： PROBLEM TO BE SOLVED: To provide an investigation method that investigates ground with simple experimental equipment in consideration of the strength of an improver itself, an improvement method that improves ground with the investigation method, and the like.
SOLUTION: A sample of ground is taken (Step 101), and the sample taken is subjected to a laboratory mixing test, which computes a relation between improver specifications and a uniaxial compressive strength q
u (Step 102). A target liquefaction strength ratio R
0 is determined (Step 103). A cyclic undrained test of partially improved samples computes relations among the uniaxial compressive strength q
u , an improvement ratio and a liquefaction strength ratio R (Step 104). For the target liquefaction strength ratio R
0 , a target partial improvement ratio, a target uniaxial compressive strength q
u0 and improver specifications are determined (Step 105). Injection into the actual ground is executed with the target partial improvement ratio (Step 106), and quality investigation into the actual ground is executed (Step 107). The processes of Step 106 to 108 are repeated until the improved ground quality satisfies target improved ground quality (Step 108).

摘要： PROBLEM TO BE SOLVED: To effectively prevent liquefaction of the ground right under a structure by using steel sheet piles even if obstacles such as pipes exist at the outer periphery of a structure such as a tank. SOLUTION: Steel sheet piles 1 are circumferentially driven down to a non- liquefaction ground bed in the vicinity of the inside of the tank side plates, in the underside of the bottom plates of the tank 3 to form a ring-shaped liquefaction preventive structure. Further, concrete 2 is circumferentially placed at the top of the steel sheet piles to prevent the tank body from settling down. By driving steel sheet piles 1 from the inside of the tank 3, the steel sheet piles can be driven without removal of pipes or the like arranged at the outer peripheral part of the tank. Further, the shear resistance of the ground right under the tank can be increased by the steel sheet piles 1 and the concrete 2 to effectively prevent the liquefaction.

摘要： PROBLEM TO BE SOLVED: To largely reduce cost by implementing a countermeasure while operating a tank without requiring to remove and transfer an existing pipe, while easily implementing a local part slide countermeasure of an existing structure such as an existing tank. SOLUTION: A required safety factor 1.1 is secured by improving a safety factor by increasing a resistance force to a slide by driving a plurality of steel bar-shaped members 3 such as a well point pipe and a reinforcement of a thick diameter at a predetermined interval in the tank radial direction in a predetermined range in the tank radial direction of the outside peripheral ground of the existing tank 1 to the local part slide surface (a circular arc slide surface) A of the existing tank (an old law tank) 1 manufactured at an old standard. The bar-shaped members 3 are arranged in an existing area of the local part slide A so as to penetrate the local part slide surface A, and also arranged in an outside area of the local part slide surface A, and the required resistance force is secured.
