摘要： PROBLEM TO BE SOLVED: To provide a manhole connection body which is resistant to attack by gaseous hydrogen sulfide generated from soil water.
SOLUTION: The manhole connection body A is formed of a manhole closed-end cylinder body 3, a manhole cylinder body 2, a resin invert 4 and a resin cylindrical connection body 5 arranged in the manhole closed-end cylinder body 3 and the manhole cylinder body 2, a rubber seal member 7 for ensuring the watertightness at a connection portion, and a connecting means for watertightly connecting the cylinder bodies together. By virtue of this formation, an inner wall surface of each of the manhole closed-end cylinder body 3 and the manhole cylinder body 2 is not exposed to gaseous hydrogen sulfide generated from soil water, and therefore the manhole connection body A is protected from attack of gaseous hydrogen sulfide.

摘要： PROBLEM TO BE SOLVED: To make temporary fixation of a flexible connecting member certain by a method wherein reinforcing bars are arranged between an inner form and an outer form, and the flexible connecting member is temporarily fixed with a temporary fixation member temporarily fixed to the reinforcing bars. SOLUTION: While an inner form 4a and an outer form 4b are fabricated perpendicularly, a pair of reinforcing bars 5 are erected between the inner form 4a and the outer form 4b at a specified interval. A temporary fixation member 7, made from a reinforcing bar or the like, is inserted horizontally through a fixation hole 2a formed at the lower end of a flexible connecting member 2. The temporary fixation members 7 are attached at the upper ends of the reinforcing bars 5, perpendicularly against the inner form 4a and the outer form 4b at specified intervals along the peripheries of the inner form 4a and the outer form 4b. Then, concrete 6 is cast between the inner form 4a and the outer form 4b, and thereby a box culvert main body is constructed.

摘要： PROBLEM TO BE SOLVED: To provide a method for injecting and filling concrete by which it is possible to prevent a change in the fluidity and compounding of the concrete from occurring and also prevent the faulty filling of the concrete or the non- homogenization of the cured concrete from occurring, when infecting the concrete into and filling the interior of a tubular member with the concrete. SOLUTION: This method for injecting and filling concrete is to inject the concrete 2 into the interior of a tubular member 1 and filling it with the concrete 2, and when injecting the concrete 2 from the lower part into the upper part of the tubular member 1, a mortar layer 3 is formed on the top face of the concrete 2 in the tubular member 1. Thus the mortar layer 3 is made to stick to the inner face of the tubular member 1 ahead of the concrete by the ascent of the concrete 2 under its injection pressure.
