摘要： PROBLEM TO BE SOLVED: To provide a stabilizing method of excavation object earth in a shielding construction method, for easily removing a filler, hardly leaving a solid material, and capable of easily disposing the removed filler.
SOLUTION: The filler reveals a viscosity of 1,000 to 12,000 cp or higher by adding water, and is formed of a water absorptive resin degelled by adding a dispersant. When on standby, a cutting face 25 is stabilized by filling the filler 38 put in a gel state by adding the water in a void and a chamber 7, and when starting excavation, a degelling agent is injected into the filled filler 38 before this start, and sucked and removed in a degelled liquid state. When a water permeable stratum such as a gravel layer is exposed to the cutting face of the excavation object earth, dissipation via its water permeable stratum is prevented by setting the viscosity of the filler 38 to 5,000 cP or higher.

摘要： PROBLEM TO BE SOLVED: To provide a water conducting structure and a method of forming a water conducting layer which can surely exhibit water permeability in a short time without taking labor and time after filling a back filling material. SOLUTION: In the water conducting structure 1, a bag body 4 in which only aggregates 3 are filled so as to contact with each other is installed in a tail void 6 so as to closely contact with the excavated surface of a tunnel 2 and the outer peripheral surface of a segment 5, which is a covering material. The water conducting structure 1 has a function for conducting upstream groundwater to the downstream side through spaces 4c of the bag body 4 and spaces 7 formed between the aggregates 3. The back filling material which is made into a flow state in a tank by mixing the aggregates 3 with a cellular material is filled into the bag body 4. The cellular material poured into the bag body 4 is discharged from the inside to the outside of the bag body 4 through the spaces 4c. As a result, the cellular material between the aggregates 3 can be discharged from the inside of the bag body 4 in a short time, whereby the inside of the bag body 4 becomes a state capable of conducting water immediately after completing the filling work.

摘要： PROBLEM TO BE SOLVED: To provide a backfilling material that can perform water permeability easily and certainly in a short time after being filled into a clearance in the ground, a method for forming a water-permeable layer using the same, and the water-permeable layer. SOLUTION: The backfilling material is made by mixing a hardening material to harden with lapse of time, an expanding agent to inflate by generating a gas in the reaction with an alkali, and a water-absorbing polymer to dehydrate and shrink in an alkaline environment. The backfilling material is manufactured by kneading the hardening material and the expanding agent to prepare a mixture and then mixing the gel-like or powdery water-absorbing polymer with the mixture. The water-absorbing polymer is added just before or at the same time when a tail void is filled, and the backfilling material is thus made a hard body having water permeability and strength.

摘要： PROBLEM TO BE SOLVED: To provide a natural ground stabilizing method for use in a shield tunneling method, for stabilizing the natural ground on the periphery of a shield machine, and also stabilizing the natural ground on the periphery of a lining structure after forming the lining structure by segments.
SOLUTION: The natural ground stabilizing method has a filler injecting step in which a filler is preliminarily injected from an injection hole formed in an outer peripheral portion of a main body of the shield machine into a cavity between the main body and an excavated hole 20, to thereby stabilize the natural ground 8 on the periphery of the shield machine main body, and a back-filling material injection step in which a back-filling material 44 is injected from an injection hole formed in the segment 22 to replace the filling material by the back-filling material 44, and stabilizing the natural ground 8 on the periphery of the segment 22. The filler is formed of a hydrophilic resin which is gelatinized upon addition of water to exert a viscosity of 1,000 to 12,000 cP, and ungelatinized upon addition of a dispersing agent. When the filler is injected, the water-added gelatinous filler is injected, whereas when the back-filling material is injected, the dispersing agent is injected from the injection hole formed in the segment 22 before injection of the back-filling material.
