Further, the seal body 3 installed in the frame body 2 absorbs water when it comes into contact with water, crosslinks the constituent molecules, and at the same time expands by encapsulating the absorbed water, thereby increasing its volume and applying pressure from the outside. Even if the frame body 2 is molded into a thin rectangular parallelepiped, a synthetic polymer-based water-absorbing polymer that does not separate water, that is, retains an expanded state is used. In addition, the size thereof is larger than at least the volume of the frame body 2 when it absorbs water and expands, and the size thereof is larger than the open portions 9 and 10 formed on both side surfaces of the frame body 2. Need to be present.

Although the expanded seal body 3 becomes larger than the volume of the frame body 2, the frame pieces 5, 6, 7, 8 (see FIG. 1) prevent expansion in the vertical direction and the front-back direction. As shown, it protrudes from the open parts 9 and 10 formed on both sides and the joint part 14
Side faces 15 and 16 of the revetment structure 12 and 13 that form the
The joint portion 14 is completely sealed by being pressed and closely contacted with each other.

Therefore, the joint portion 14 is completely sealed by the sealing body 3 which maintains the expanded state being in close contact with the side surfaces 15 and 16 in the elastic state, and prevents the outflow of the earth and sand due to the water flow or the waves. Further, even if the revetment structures 12 and 13 are significantly unequally settled to cause a vertical difference, the sheet body 3 is in surface contact with the side surfaces 15 and 16, and is kept in a sealed state without being damaged.

Further, in order to install the seal member 1, it suffices to remove the waterproof film 4 to expose the seal body 3 and insert the frame body 2 into the joint portion 14, and further, the work in water as in the conventional case is not required. It is extremely easy to work on the top of the revetment structure. Since the sealing body 3 is covered with the waterproof film 4 before installation, it is convenient for storage and transportation without absorbing rainwater or the like and expanding. Particularly, in this embodiment, the sheet body 3 covered with the waterproof film 4 is the frame body 2.
The frame 2 serves as a protective material and can effectively prevent damage to the waterproof film 4 during transportation and storage.

更にシール体3は枠体2に内装されてほぼ一定の姿勢を

Furthermore, FIG. 6 shows another embodiment of the present invention. This embodiment has the same overall structure as the embodiment shown in FIG. 1, but the sealing body 3 is in an exposed state. Is different from the above in that the frame body 2 is installed inside and the frame body 2 is covered with the waterproof film 4. The waterproof film 4 is provided with a pair of vertically extending cords 19 and 20 at substantially the center of both side surfaces thereof. The cords 19 and 20 are provided at a predetermined interval on the waterproof film 4. Further, the fixing portions 22 are inserted in the string loops 21 and at the lower end and in the vicinity of each of the string loops 21.

The joint seal member 1 having such a structure is inserted into the joint portion as in the embodiment shown in FIG. 1, but in this embodiment, the joint member is inserted into the joint portion while the waterproof film 4 is attached, and then the joint portion is inserted. By pulling the upper ends of the cords 19, 20 projecting to the upper part of the portion, the waterproof film 4 is torn at the fixing portion 22 and pulled up together with the cords 19, 20 to expose the frame body 2 and the seal body 3. Similarly to the embodiment shown in FIG. 1, the seal body 3 absorbs water and expands to seal the joint.

Although the frame body 2 and the seal body 3 are formed in a rectangular shape in the above-described embodiment, they may have other shapes such as a rod shape as long as they seal the joint portion when the seal body 3 expands. Alternatively, a plurality of them may be arranged at appropriate intervals.
