点があった。2. Description of the Related Art The prior art will now be described by taking the present invention as an example of a joint portion of a large diameter intake pipe or discharge pipe laid on the seabed. In the work of the joint portion of such a large-diameter pipe, pipe connection can be surely performed in a short time, and antipermanent watertightness is required. For example, when connecting a large-diameter pipe used for the intake of cooling water in thermal power generation, the flanges formed at both pipe ends are bolted through rubber packing, but the core of the bolt hole It has been pointed out that it takes a lot of time for matching and the workability is not good. For this reason, there has been considered a means for facilitating the alignment of the bolt holes by making one of the flanges a so-called loose flange that allows the flange to rotate in the circumferential direction of the pipe. However, even in this case, when the number of bolts is large, there is a drawback in that the bolt tightening work requires a long time and is particularly dangerous because the work is performed in water.

よく又短時間で施工が完了するという利点がある。As a modification of these techniques, Japanese Patent Laid-Open No. 6-249377 proposes a new pipe joint structure. This is to expand the end of one pipe, insert the end of the other pipe into the expanded part, and arrange an annular water swelling rubber in the clearance part of both to seal the water around the joint with rubber. Is intended to seal by absorbing and swelling. According to this proposal, basically, the bolting work is not performed in the joint structure, so that the workability is good and the construction is completed in a short time.

要があり、このクリアランスが大きいと水膨潤ゴムが水
を吸収して膨潤したとしても充分な止水圧が得られない
という欠点が指摘され、新たな改良が求められていた。However, for the reason of workability such as insertion work of the ends of both pipes, it is necessary to make a clearance between the enlarged diameter portion in which the water-swelling rubber is interposed and the pipe surface on the other side, It has been pointed out that if this clearance is large, a sufficient water-stopping pressure cannot be obtained even if the water-swelling rubber absorbs water and swells, and a new improvement has been demanded.

m 2 cannot always be obtained, and particularly when used in a place with a large clearance, the degree of freedom of swelling of rubber is large with respect to this clearance, and the expansion pressure does not effectively become the contact surface pressure. Further, if the degree of swelling is large, the elastic modulus of the rubber is reduced to that extent, and there is a drawback that the contact surface pressure does not increase even on this side. And, in general, the clearances at both ends of the pipe are rarely uniform, and it is possible to deal with uneven clearances only with water-swelling rubber,
It is almost impossible to secure the water stopping ability.

If the soil and dirt behind it are sucked into the sea from the clearance between the two sons, it will lead to a major accident such as ground depression and marine pollution, so the seal at this clearance is extremely important. The number of cases required in the offshore sea is large, the behavior of the caisson is large, and the clearance intervals often vary. For this reason, advanced techniques such as the followability of the seal material, durability, and workability are demanded, but the current situation is that there is still not enough.

A combination of a swellable rubber hollow body and a water swelling rubber, the hollow part is filled with a filler to swell the annular body to secure the contact surface pressure, and the water swelling rubber is used to maintain the waterproof property. is there.

とは勿論である。According to the water stopping method of the present invention, a rubber inflatable hollow body having a water swelling rubber on its surface is fitted between members facing each other with a clearance,
The hollow portion is filled with a filler to expand the hollow body to close the clearance between the members and then to swell the water-swelling rubber. Further, examples of the filler to be filled in the hollow portion include urethane resin, epoxy resin, mortar and the like, but it goes without saying that they are not limited to these.

In general, a hollow body made of rubber is flatly formed, and a reinforcing fiber layer is embedded in the rubber with the hollow portion sandwiched therebetween. It is preferable that the outer surface of the water-swelling rubber layer is provided with a ridge.

る。According to the above-described water stopping method of the present invention, even if the clearance at the end portion of the member to be connected is large, the clearance can be compensated for by expanding the hollow body made of rubber. In this state, the water-swelling rubber is swollen, and the swollen rubber exhibits a water-stopping effect by sufficiently securing the elastic force. There are various conceivable methods of filling the hollow portion with the filler, for example, a method of pressurizing the filler with air to forcibly fill the hollow portion, or a squeeze used for forcibly transferring concrete or mortar. It is needless to say that a formula pump or the like can be used, but is not limited to these.

Even if there is a large clearance between the members to be connected, it is possible to cope with this, and the workability is also excellent. Further, the variation of the clearance can be absorbed by the swelling function of the hollow portion, and a uniform contact surface pressure can be obtained. That is, by filling the hollow part from the mouthpiece with a filler, the filling material expands to obtain a contact surface pressure, and then a water-swelling rubber is arranged at a portion in contact with the surface of the member to be connected to swell it to obtain a water blocking effect. I will get it. The reinforcing fiber layer embedded in the rubber is usually made of nylon fiber or polyester fiber, which is made into a canvas shape, or a plurality of layers are laminated at a predetermined angle. still,
Examples of the water-swellable rubber used in the present invention include a rubber-like elastic body obtained by molecularly cross-linking a hydrophilic polymer mainly composed of ethylenoxide, but other superabsorbent polymers.
It is possible to use a rubber in which is mixed, and there is no particular limitation.
