摘要： PROBLEM TO BE SOLVED: To provide a cofferdam construction method etc. which allows an easy cofferdam construction for a water area.SOLUTION: A joint surface consisted of a side wall part 2 and a bottom part 4 opens a cofferdam structure 1 with an internal part at least partitioned into floating parts 100, 400, an inflowing part 200 and a pouring part 300. In a state where the side wall part 2 is made to float on water surface laterally, water is poured into the pouring part 300 and flows into the inflowing part 200 to set the bottom part 4 to down into the water, thus, putting the side wall part 2 to a state of longitudinally floating on the water. The side surface 3a of a dam body 3 of the cofferdam structure 1 is then positioned alongside the end face of joint surface formed from the bottom part 4 and side wall part 2. Thereafter, the space surrounded by the cofferdam structure 1 and the side face 3a of the dam body 3 is drained of water.

摘要： PURPOSE:To more easily construct a vertical hole for installing a heater pipe in an underground continued wall, and recycle the used material. CONSTITUTION:A concrete release material is applied to the outer circumferential surface of a hose-like bag 1 having a closed top end. One end of a cord 7 is connected to the inside of the top end part of the bag 1, and the other end is protruded from the opening part 9 of the bag 1 to the outside. The top end part of the bag 1 is mounted on a reinforcement cage 11a for a deepest part by a temporary holding tool. While the reinforcement cage is successively built upward, the extended part of the bag 1 is mounted on the reinforcement cage. A fluidized material 17 is injected into the bag 1 and pressurized to keep a prescribed space form. After the concrete 19 placed in the circumference is solidified, the cord 7 is pulled in a direction B, whereby the bag 1 is pulled up to the inside, a vertical hole 21 is simultaneously formed from the top end part. A prescribed heater pipe is installed in the vertical hole 21, and the void is grouted with cement milk.

摘要： PROBLEM TO BE SOLVED: To make it possible to provide a large ductility jointing structure when it is possible to embody cost reduction by using the weight of an underground continuous wall which covers up the shortage of the weight of skeleton against buoyancy and execute joining work under a simple and low cost structure. SOLUTION: A bored precast anchor 11 for the coupling of connecting reinforcing bar 18 is preliminarily mounted on an underground continuous wall 1 to be constructed. After having excavated the front surface of the underground continuous wall 1, the connecting reinforcing bar 18 is mounted on the bored precast anchor 11. Further after a cage reinforcing bar 21 is mounted on the connecting reinforcing bar 18, concrete is cast, thereby providing projectingly a reinforced concrete-made joining area 19 on the underground continuous wall 1 integrally. As occasion arises, a buffer material 20 is provided on the top of the joining area 19, thereby constructing a skeleton 10 so that this joining area may be incorporated.

摘要： PURPOSE:To restrain the occurrence of eccentric bending moment in the side wall of an underground tank by forming a part of the joining surface of the base plate and the side wall so as to be oblique to the horizon. CONSTITUTION:A cylindrical underground continuous wall 3 is provided inside the ground, and the ground inside the continuous wall 3 is excavated up to a prescribed depth, and then a baseplate 7 and a side wall 9 are provided, and the underpart of the baseplate 7 and the side wall 9 is worked so that the joining surface 13 of the baseplate 7 and the side wall 9 is oblique to the horizon. When the underground water level inside the continuous wall 3 is equalized to that of the outside ground at the time of high water-level operation or empty liquid, buoyancy is applied to the body and a force F1 is added to the side wall 9 from the baseplate 7, however, since the force F1 acts obliquely, the bending moment M1 of the side wall 9 is hardly caused. While, when the underground water level 17b is lowered by pumping the underground water inside the continuous wall 3 by means of pumping equipment, a force F2 is added to the side wall 9 from the baseplate 7 by the load of LNG 15 or the like, however, since the force F2 acts obliquely, the bending moment M2 of the side wall 9 is hardly caused.

摘要： PURPOSE:To shorten construction period by making a double-wall structure of the outer circumferential part of a caisson, and excavating and sinking this part by the conventional compression-air type caisson method, and then excavating the remaining central part by utilizing the double-wall part. CONSTITUTION:A part of the lower part of the caisson in the outer circumferential double-wall part is constructed and installed in the ground 5 at an installation place, and necessary machines are fitted to the body part 2 of the double- wall caisson, and the caisson is sunk to a prescribed depth while constructing the body in the upper part of the caisson, and then concrete is filled in the inside of the compression air chamber. Thereafter, while utilizing the double-wall part as a retaining wall and water stopping wall, the excavation of the central part 3 is carried out, and the bottom base 8 is constructed with concrete. If necessary, the ground is improved so as to reduce the quantity of water permeating into the inside of the caisson as low as possible. Thus, the amount of excavation can be decreased, and the cost necessary for the installation of the caisson can be reduced, and also the construction period can be shortened.
