PROBLEM TO BE SOLVED: To provide a connection structure of drain materials, capable of suppressing the decline of flexibility and the formation of a level difference in a connection part and keeping the drainage function of the drain materials.SOLUTION: The connection structure of the drain materials of this invention includes a flexible and water permeable sleeve 6 to which the end part 10 of a belt-like first drain material 1 and the end part 30 of a second drain material 3 are inserted so as to be abutted, and which is fixed to the first drain material 1 and the second drain material 3. The sleeve 6 may include one or more flexible planar member(s) 5 thinner than the first drain material 1 and the second drain material 3.

PROBLEM TO BE SOLVED: To obtain vacuum consolidation effect by reducing the pressure inside a bag filled with sludge to negative pressure in a state where the bag is exposed to the atmosphere. SOLUTION: Sucking force is applied to a drain board 2 disposed so as to be laid under the water permeable bag 1 filled with sludge, whereby the moisture of the sludge in the bag 1 is sucked through the drain board 2 in a state where outside air can enter into the bag 1. In addition to the self-weight consolidation effect of the bag 1 containing the sludge, the vacuum consolidation effect due to a pressure difference between the atmospheric pressure and a pressure inside the bag 1 can be obtained, whereby the sludge in the bag 1 can be dewatered in a short time.

Abstract:
PROBLEM TO BE SOLVED: To provide a water reservoir with a water drainage device for draining water to the outside from within a recessed shape water storage area formed on a ground, and in connection with this water reservoir, ensure that the water inside the water storage area can be prevented from seeping into the ground through whichever region of the water drainage device. SOLUTION: This water reservoir 1 includes the water drainage device 15 which drains water 2 inside the water storage area 4 through openings 12 and 13 formed in inner and outer impervious sheets 9 and 10 laid on the inner surface of the water storage area 4. The water drainage device 15 comprises inner and outer impervious sheet pieces 19 and 20 which extend along one inner surface part of the water storage area 4 corresponding mutually to each opening 12 and 13, and are mutually joined to the opening edge part of each opening 12 and 13, a water drainage pipe 23 which is introduced into through holes 21 and 22, each formed in inner and outer impervious sheet pieces 19 and 20, with the outer circumferential surface of the water drainage pipe 23 being joined W1 to the hole edge part of each through hole 21 and 22, and an impervious material 29 packed into a space 28 surrounded by the inner and outer impervious sheet pieces 19 and 20 and the water drainage pipe 23.

Abstract:
PROBLEM TO BE SOLVED: To provide a protective plate-coupling method which improves the quality of a joint part of protective plates, keeps consistency between a protective material layer and a coupling sheet in the joint part, and improves operational efficiency. SOLUTION: Protective plates A and A, which are adjacent to each other, are arranged to form a gap, and the adjacent protective plates are coupled with each other with a lower side coupling sheet to form a cavity 4 to be filled. The upper surface aperture part of the cavity 4 to be filled is covered with an upper side coupling sheet B1 which is formed of a transparent or translucent material, and both the side end parts of the upper side coupling sheet B1 are placed on the adjacent protective plates, and the one side end part of the upper side coupling sheet B1 is coupled with one protective plate A, and the other side end part of the upper side coupling sheet B1 is coupled with the other protective plate A in the direction of the length of the cavity 4 to be filled. Then, the injection hole of an injecting machine is inserted into the cavity 4 to be filled, from the unjointed part between the other side end part of the upper side coupling sheet B1 and the other protective plate, to inject a setting-type protective material into the cavity 4 to be filled at the jointed part.

Abstract:
PROBLEM TO BE SOLVED: To provide an exercise device by which a user can automatically perform the stretch or rehabilitation exercise for the arm and the shoulder while safely and sanitarily holding the hand of the user without imposing any stress. SOLUTION: The exercise device allows the user to automatically do the stretch or rehabilitation exercises of the arm and shoulder by retaining the hand H of the user by a retaining part 6 and moving or rotating the retaining part 6. When the retaining part 6 retains the hand H of the user, The elastic body 23 of a pressure member 17 is made to pressurize a part from the back of the hand to fingertips in the hand H gripping a grip member 16, and then, the hand H is held between the grip member 16 and the pressure member 17.
