Abstract: PROBLEM TO BE SOLVED: To provide a method of curing tunnel lining concrete, which is superior in heat insulating curing function and wet curing function, implemented without using large-scale facilities, and does not narrow a work space in a curing zone.
SOLUTION: According to the method, a curing sheet 2 is stuck to a surface of the lining concrete 1 via a wet adhesive 3. The curing sheet 2 is formed of a sheet having a thickness on the order of 1.0 to 20 mm, and made of polyvinyl chloride, expanded polyethylene, or the like, for instance. The wet adhesive 3 must be inexpensive etc. because of a considerably large surface area of the lining concrete 1, and therefore it is formed of a material obtained by diluting a water-soluble polymer, e.g. methylcellulose (MC), for increasing the viscosity of the concrete etc., with water to a concentration on the order of 1/10 to 1/10,000.

Abstract: PROBLEM TO BE SOLVED: To provide a natural ground reinforcing method for forepiling work, face reinforcing work, etc., which reinforces the front natural ground when e.g. a tunnel, an underground opening, etc. are excavated, which enhances adhesion at the weak material age of a cement-based consolidation material for anchoring a reinforcing pipe as a reinforcing material, which prevents the outflow and runway of the consolidation material even in the production of sump water, which can bring about a great anchoring force even in the fragile condition of the natural ground by increasing rigidity so as to enhance a reinforcing effect. SOLUTION: In this natural ground reinforcing method, a drilled hole (h) is formed at a predetermined angle of elevation in the natural ground 1 ahead of a cutting face from inside a tunnel excavation space T; concurrently with that, a reinforcing pipe 6, which is formed by sequentially connecting one or more pipes with an ejection hole for the consolidation material to a peripheral wall, is driven into the drilled hole (h); and an anchoring or consolidation area 8 is formed for reinforcement in the reinforcing pipe 6 and the natural ground 1 around it by injecting the consolidation material into the reinforcing pipe 6. Characteristically, a material, in which glass fibers are mixed into the cement-based consolidation material such as cement milk and cement mortar, is used as the consolidation material.

Abstract: PROBLEM TO BE SOLVED: To provide a method for reinforcing natural ground in a tunnel, which enables construction to be efficiently performed by using a cement-based material, without use of an expensive urethane-based material.
SOLUTION: In this method for reinforcing the natural ground in the tunnel, mortar with quick-hardening properties is placed by being injected into the natural ground from the inside of the tunnel. A mortar-kneaded material, which is mixed in such a manner that compressive strength at a material age of 3 h is set at 5 N/mm
2 or more at a temperature in placing, is prepared and placed by means of a pump which continuously performs the kneading and pumping of the mortar in a uniaxial pipe through the use of the rotation of a screw axis member. Preferably, a water/powder ratio of the mortar is set to be in the range of 30-40%.

Abstract: PROBLEM TO BE SOLVED: To provide a water stopping material injection method and a levee body, efficiently and economically performing water stopping injection by a simple piping method in cement milk injection requiring water-tightness.
SOLUTION: With a grout pipe 33 set in a grout hole 13 formed in a hydraulic iron pipe 3, filling concrete 17 is placed between the hydraulic iron pipe 3 and the levee body concrete 17, and the inside of the grout pipe 33 is drilled. Subsequently, a forked pipe 39 is connected to the grout pipe 33, and an evacuate pipe 59 is set in the grout pipe 33 and the forked pipe 39. While air and water 57 are extracted from the evacuation pipe 59, the space between the filling concrete 17 and the levee body concrete 1 is filled with a water stopping material 63. After the end of filling the water stopping material, the end of the evacuation pipe 59 is blocked up by caulking 65, and the forked pipe 39 is removed. Further, the evacuation pipe 59 is cut at the position of the hydraulic iron pipe 3, and a lid 67 is set in the grout hole 13.
