摘要： PROBLEM TO BE SOLVED: To absorb a movement in an axial direction so as to maintain an initial connection state by laying a bolt stick over the vertical piece of a double- L type plate and elastically fixing an elastic member to the bolt stick protruded outward more than the vertical piece of one L type plate. SOLUTION: A bolt stick 10 is laid over the vertical piece 7b of an L type plate 7 in the outside of a receiving port 4 and the vertical piece 7b of an L type plate 7 in the outside of an inserting port 3. One end of protruded outward more than the vertical piece 7b, an elastic member 11 is fitted in its protruded stick part, a nut 13 is engaged with one end of the bolt stick 10 protruded from the elastic member via a washer 12 and thereby pulling-out is prevented. Thus, when a force of a direction for moving both cooperative grooves A and A' is applied to the connection part of the electric wire grooves A and A', the elastic member 11 is compressed and if its load is released, both cooperative grooves A and A' are relatively moved in an axial direction by the elastic force of the elastic member 11 and returned to an original state.

摘要： PROBLEM TO BE SOLVED: To improve the workability of a concrete guard fence. SOLUTION: Precast concrete plates 1, 1 are installed on both sides across the stanchions S of an existing guard fence. Concrete 24 is filled between the precast concrete plates 1, 1 on both sides from the gap 23 between the upper sections of the precast concrete plates 1, 1. The precast concrete plates 1, 1 are used as a formwork, the concrete 24 is filled at the site, and the filled concrete 24, the precast concrete plates 1, 1, and the stanchions S of the existing guard fence are integrated.

摘要： PROBLEM TO BE SOLVED: To form the inner circumferential surface sides of the mutual connecting sections of propulsive pipes smoothly. SOLUTION: An inner circumferential collar 20 formed of a thin metallic pipe or a thin synthetic resin pipe is projected backwards from the rear end face of a Hume pipe (the propulsive pipe) 10A in the front and fixed on the inner circumferential surface side of the rear end section of the Hume pipe 10A. The front section of a cylindrical connecting sleeve 24 having elasticity is fast stuck and fitted slidably on the outer circumferential surface side of the rear projecting section of the inner circumferential collar 20. A width expanding section 13 for fixing is molded on the inner circumferential surface side of the front end section of the Hume pipe 10B at a rear section in response to the wall thickness of the connecting sleeve 24, and a width expanding section 14 for bending is molded in the front section while being opened to the front end face side. The front section of the connecting sleeve 24 is arranged on the inner circumferential surface side of the width expanding section 14 for bending in a bendable manner, and the rear section of the connecting sleeve 24 is pushed and fastened to the inner circumferential side of the width expanding section 13 for fixing from the inner circumferential surface side by a cylindrical metal fitting 26 plastically deformed in an expanding shape to the outer circumferential side and used for fixing.

摘要： PROBLEM TO BE SOLVED: To provide a pipeline inner surface water stop method and a clamp mounting device used in this method enabling a worker to smoothly perform pipeline laying work mainly for sewage or the like with a small diameter where he cannot enter or it is hard for him to enter and enabling the worker to perform leakage place repairing work easily in a short time without digging up buried sediment. SOLUTION: A water stop cylindrical body 15 formed of elastic material of such a size as to come in contact with the inner peripheral surface of a joint part or another leakage part of a pipeline is inserted into the joint part or another leakage part. A ring-like clamp 16a formed of metallic material is then inserted in the water stop cylindrical body 15, and pressure is applied to the ring-like clamp 16a in the direction of pushing to enlarge from its inner surface so as to plastically deform and fix the water stop cylindrical body 15 to the inner surface of a buried pipe from the inner surface. The ring-like clamp 16a is mounted using a clamp mounting device provided with a cylindrical elastic pressure member 25 radially deformed by axial compression, an inner surface support cylinder 23 for regulating the center direction deformation of the elastic pressure member 25, a pair of pressure rings 26a, 26b axially pressurizing both ends of the elastic pressure member 25, and a jack 21 for relatively moving both pressure rings 26a, 26b in an axial direction.

摘要： PROBLEM TO BE SOLVED: To provide a utility tunnel though which electric wires, cables, etc. can be passed smoothly without damaging them, by inserting pipes made of synthetic resin into the storage of the sheath pipe where a storage which can have a plurality of pipes passed is made of concrete material. SOLUTION: Pipes 2 are inserted into a sheath pipe 1 made of concrete made in roughly regular tetragon in external form, and a storage 3 in the form where four pieces of pipes 2 are put together over the full length is made inside the sheath pipe 1, and besides one hand in longitudinal direction of the sheath pipe 1 is made into a spigot 1a and the other hand is made a socket 1b. For one spigot 1a of the sheath pipe 1, the periphery is made in the shape of tiers which become gradually smaller across toward the side end, and also a packing 4 is attached to the periphery on this side of the side end. Moreover, for the other socket 1b, a collar 5 made of stainless is constituted, being fixed protuberantly outward from the side end, and a pipe 2 made of synthetic resin is inserted into the storage 3 of the sheath pipe 1.
