摘要： PROBLEM TO BE SOLVED: To provide a construction method in which the voids of ballast just under a sleeper and in the periphery of the sleeper are filled with a small amount of a stabilizer in a short time, using a ballasted track composed of ballast in which soil and sand are mixed in a comparatively small amount as the object because a rail joint for a railway track is at the maximum weak-point place of the track from the viewpoints of comfortableness to drive, stability on car traveling and track maintenance works owing to a large impact by a train, ballast is stabilized and ballast can be reinforced efficiently. SOLUTION: The injection stabilizer in which a flow time and a gel time are controlled is injected from injection holes bored near rail fastening sections for the sleepers, the voids of ballast are filled without installing forms and the ballast is stabilized in a short time, and only ballast sections bearing the load dispersion functions of the train are reinforced efficiently.

摘要： PROBLEM TO BE SOLVED: To provide a ballast reinforcing construction method in which the depression of a rail joint, particularly a pumping sleeper is improved efficiently by filling an opening generated under a sleeper in a rail joint section with a small amount of quick setting grout because the rail joint for a railway track is at the maximum weak-point place of the track from the viewpoints of com fortableness to drive, stability on car traveling and track maintenance works owing to a large impact by a train. SOLUTION: The quick setting grout is injected previously into the voids of ballast in the periphery of the sleepers or timber frames are installed to the peripheral sections of the sleepers and shielding walls are mounted in ballast, the quick setting grout in which a usable time, a flow time and a gel time are controlled is injected into the openings generated under the sleepers from injection holes bored near the rail fastening sections of the sleepers and the grout is stabilized in a short time, the depression of the rail joints is corrected and a maintenance-work period is lengthened, and the rail joint sections are reinforced efficiently at low cost.

摘要： PURPOSE: To easily correct disturbance in the case when a railroad changes in ground. CONSTITUTION: A flexible bag body 10 is provided along the longitudinal direction under a sleeper 3 on a roadway ground provided with the sleeper 3 on track bed ballast 2 of the roadway ground. A filler containing ballast 11 is filled in the inside of it, and the track bed ballast 2 is laid between these flexible bag bodies 10 and under them. When sinking of a rail 4 is caused or there is a danger o sinking, an amount of sinking is compensated by supplementally filling the filler in the flexible bag bodies 10.

摘要： PURPOSE:To lay down an injection outer tube while preventing the underground water from ejecting. CONSTITUTION:Ground is bored up to a specified depth by a casing 4 equipped with a detachable bit at the front. After an injection outer tube 7 is inserted in this casing 4, only the casing is pulled out. At this time, the reverse flow on excavating the bore can be prevented by a check valve and a preventer 3 equipped in the front bit 5. The reverse flow on pulling out the casing 4 is prevented by a packing agent A filled in the clearance between the infection outer tube 7 and the casing 4 and a packing agent B filled in the guide tube 1.
