PROBLEM TO BE SOLVED: To provide an inspection apparatus which can be positioned to both side sections of a bridge and which enables the efficient and safe execution of inspection work.SOLUTION: An inspection apparatus 1 includes: traveling sections 2 which have crawlers mounted on both the sides of an undercarriage comprising a machine body frame 20; a driving section 3 which is provided in the rear of the machine body frame 20; an inspection section 5 which is attached to the machine body frame 20 on the front side of the driving section 3 and which inspects an inspection object by taking an image of the inspection object from below; and an operation display section 6 which is provided between the driving section 3 and the inspection section 5 and which displays the operation of the inspection section 5 and the result of an inspection thereby.
Abstract:
PROBLEM TO BE SOLVED: To solve the problem of requiring much cost and labor for manufacture and installation of temporary receiving members in large-scale, which is required during the time, generally as long as several ten days to several months, until the completion of the installation/fixation of a new support device by disassembling and removing an old support device in replacing work of a support device of a pier. SOLUTION: This replacing construction method comprises a preparing process of installing a temporary receiving jack for the hole inside in a drilled hole, by drilling the hole in the horizontal direction in the pier of a lower part of the support device, before the replacing work of the support device; a process of removing a concrete skeleton and the old support device of an upper part of the drilled hole in the next place, by removing the temporary receiving jack for the hole inside installed in the drilled hole, after temporarily receiving a bridge girder by using the temporary receiving jack; and a process of removing the temporary receiving jack, after fixing the support device and a pier upper part by filling a hardening material by installing the new support device in a removed concrete skeleton part.

Abstract:
PROBLEM TO BE SOLVED: To provide a pipe bore diameter measuring device capable of directly measuring a change (change quantity) in pipe bore diameter through a displacement gauge, performing accurate measurement regardless of the magnitude of the displacement quantity, and being effectively applied to, particularly, bore diameter measurement of an existing conduit with relatively large bore diameter change, for example, an existing sewage conduit with minor bore diameter. SOLUTION: This device comprises a body part set on the axial line within a pipe of measuring object; a centering means for regularly holding the body part on the axial line within the pipe; a plurality of contacts arranged in a plurality of positions on the circumference of the body part; holding and pressing means protruded radially (in pipe diameter direction) from a plurality of positions on the body part, each of the means independently holding each contact to be linearly movable in the pipe diameter direction in the protruded state, and independently pressing the contact to the pipe inner surface in an optionally moved position; a plurality of displacement gauges set on the body part so that measuring parts are linearly movable in the pipe axial direction; and a movement transmitting means linearly moving the measurement parts of the displacement gauges by a quantity corresponding to the linear moving quantity in the pipe diameter direction according to the linear movement of the contacts in the pipe diameter direction.

Abstract:
PROBLEM TO BE SOLVED: To provide a repair method for the inner surface of a pipeline which is capable of correcting a portion to be repaired of the inner surface lining having a verystrong construction in addition to excellent workability and is specially useful for repairing the inner surface of an existing large diameter sewer pipeline. SOLUTION: Cylindrical lining members are folded to flat cylindrical shapes and are carried to the inside of the pipeline through a vertical shaft for the work, thereafter, each member is shaped to a normal cubical cylindrical shape inside the pipe and is sequentially added to a predetermined length and assembled to a cylindrical body during the repair work. At least to one place at the rear surface of the cylindrical lining member, reinforcing steel members are so arranged to form a cylindrical body of a predetermined length by sequentially adding the bodies; cylindrical lining members are reinforced by inserting reinforcing steel members below linkage with the rib edge portion inside the opposing intervals of a pair of neighboring T-type ribs thereby reinforcing the cylindrical lining members; and by repeating this reinforcement, the cylindrical lining member is sequentially connected to precedingreinforced cylindrical lining member.
