A reinforcing method of path structure is provided to secure the safety and to reduce the manhour according to the enforcement and production cost. A reinforcing method of path structure comprises following steps: an enforcement path structure fabrication step(100) making the enforcement path structure water having the second path of the sectional body relatively smaller than the first path structure water for to reinforcing; a guide rail installation step establishing the guide rail for transporting the enforcement path structure in the inner surface of the first path structure; an enforcement path structure installation step which moves the enforcement path structure according to the guide rail and inserted into the first path; a reinforcing material backfill step filling back the reinforcing material between the inner circumference of the first path structure water and outer circumference of the enforcement path structure.

PURPOSE: A fixing device for repairing and reinforcing a structure is provided to improve construction by giving tension to a tensioning member through the rotation of a screw member. CONSTITUTION: A fixing device for repairing and reinforcing a structure comprises a base(110), a supporting plate(120), a first arm(130), a second arm(150), a screw member(160) and a tensioning member(170). The base is detachably combined with one side of a structure using a fixing member. The supporting plate is expanded from the base in a fixed height. The first arm is respectively hinge-coupled with a first bracket(122) located on one side of the supporting plate. The second arm is hinge-coupled at one end of the first arm using a combining member. Both side of the screw member are inserted to and screwed with a combining hole formed on the combining member. A second bracket(175) hinge-coupled with one end of the second arm is formed on one side of the tensioning member. The tensioning member is moved by sliding along one side of the base.

A culvert box is provided to make construction simple, to shorten a period of construction and to cut down on the cost of construction by installing a pair of culvert boxes buried with anchor units to four corners or each side in a longitudinal direction, and inserting steel wires to steel wire passing holes of the culvert boxes and fixing to the anchor units simply. A culvert box(200) is composed of a first culvert box(210) and a second culvert box(220), and installed continuously to the appointed length at every section of the first culvert box and the second culvert box making a pair with tensile force supplied by anchor units(100), steel wires(130) and anchorages(140) of the first and second culverts. The first and second culvert boxes are formed in empty tunnel type hollow bodies(211,221) and provided with plural steel wire passing holes formed in the longitudinal direction of the hollow bodies, anchorage mounting grooves formed on ends of the steel wire passing holes to mount each anchorage, and anchor units formed between the steel wire passing holes of the hollow bodies, or, four corners or each side in the vicinity of the steel wire passing holes. In addition, a locker is inserted from one of the hollow bodies of the first and second culvert boxes to the other hollow body to prevent culvert boxes from sinking or being distorted by subsidence of ground, an alignment projection and an alignment groove are formed on ends of the hollow bodies of the first and second culvert boxes to align the first and second culvert boxes when connecting the hollow bodies of the first and second culvert boxes continuously and mortar lines are formed on ends of the hollow bodies of the first and second culvert boxes to inject mortar between the first and second culvert boxes which come in contact with each other under pressure and to keep airtight, and a composite waterstop is inserted between the first and second culvert boxes and unified with a hydrophilic waterstop having plural grooves and a rubber ring having excellent elasticity to prevent a leakage of water.

PURPOSE: A box structure for fixing a tendon and a construction method for an underground structure using the same are provided to reduce the amount of reinforcing bars by stably applying prestress to a bending member of an underground structure. CONSTITUTION: A box structure(200) for fixing a tendon comprises a main body, tendon through holes(201), a fixing member(210), and tendon fixing holes(211). The tendon through holes are formed on the side wall of the main body. The fixing member is installed inside the main body to be inclined. The tendon fixing holes are formed in the fixing member so that the ends of tendons penetrating through the tendon through holes can be fixed.

PURPOSE: A mounting cylinder for straining wire and a method for maintaining the strain of a wire are provided to maintain the strain of a wire after wire is strained. CONSTITUTION: A mounting cylinder for straining wire comprises a cylinder block(110), a rod block(120), a cover(130), and a grip portion(140). The cylinder block draw in the fluid and generates pressure. The rod block is mounted inside the cylinder block and is moved forward and rearward by fluid. The cover closes a cylinder space(111) inside the cylinder block.

PURPOSE: A tensioning device for reinforcing a structure and a tensioning method using the same are provided to prevent structural strength decline by minimizing damage to the surface of a concrete structure. CONSTITUTION: A tensioning device(100) for reinforcing a structure is composed of fixing units(120) and a power unit(140). The fixing units are permanently fixed to grooves(112) formed in the surface of a structure. The power unit comprises a front fixing unit(144), a movable support unit(150), a fixing support unit(148), and a tensioning unit(156). The front fixing unit is fixed to the fixing unit. The movable support unit is movably installed in guide rods(146a,146b). The fixing support unit is installed in the end of the guide rods. The tensioning unit moves the movable support unit.
