Abstract: PURPOSE: A cross section restoring material including a crack sealing function and a cross section restoring method of a concrete structure using the same are provided to minimize the generation of crack in the restoration of a cross section and seal the crack by inducing carbonation to a cracked part when the crack is generated. CONSTITUTION: A cross section restoring material including a crack sealing function is comprised of a binding material, an expansion material, a crack compensating material, an admixture, and an aggregate. The crack compensating material includes poly vinyl acetate and sodium carbonate. The expansion material includes CSA, MgO, and anhydrous gypsum. Water and cross section restoring materials are mixed so that cross section mortar is formed. The cross section mortar is placed and cured in a damaged part of a concrete structure.

Abstract: PURPOSE: A girder lifting device is provided to easily and rapidly replace a bridge seat device and to absorb impact and vibration delivered to the girder and the bridge seat device, thereby improving structural stability. CONSTITUTION: A girder lifting device comprises a lifting device(200), a reinforcement member(400), and a projecting member(500). The lifting devices are arranged to be faced to each other in both sides of a girder(100). One end of the lifting device is connected to one side of the girder and the other end of the lifting device is connected to an upper one side of a pier(1) so that length is selectively varied. The reinforcement member is comprised in a lateral side of the girder. The reinforcement member shields the lateral side of the girder along a height direction of the girder and joined to the girder by a bolt(420). The projecting member is fixed to a top surface of the pier by an anchor(510).

Abstract: To improve the traveling functionality of a traveling device equipped with dual, rotating, negative-pressure suction seals. Provided is a traveling device equipped with dual, rotating, negative-pressure suction seals, which is characterized in that: a single, rotating, negative-pressure suction seal is respectively provided to the left and the right of the axis of travel of the traveling device; the distance between the rotational axis of one of the negative-pressure suction seals and the axis of travel is substantially equal to the distance between the rotational axis of the other negative-pressure suction seal and the axis of travel; the outer peripheral shape of each negative-pressure suction seal forms a shape comprising a farthest outer peripheral end portion, which is the outer peripheral end portion farthest from the rotational axis, and a nearest outer peripheral end portion, which is the outer peripheral end portion nearest to the rotational axis; and a driven wheel is provided inside each negative-pressure suction seal.
