摘要： PROBLEM TO BE SOLVED: To provide a method and a system in which a gas hydrate in a submarine stratum existing thinly and widely is mined efficiently.
SOLUTION: A spread region along the sea-bottom surface 4 of a gas-hydrate layer 2 in a submarine ground 1 is investigated, a mining base 10 equipped with a boring device 11, in which a drilling angle is operated freely, is submerged at a stable ground site in the spread region and a transport route is installed between the base 10 and a marine section. A plurality of horizontal wells 30 are drilled to the gas-hydrate layer 2 from the base 10, warm heat or a kicker is sent into the layer 2 through the wells 30 and the gas hydrate is decomposed and the decomposition-product gas of the layer 2 is gathered by the wells 30, the base 10 and the transport route 19. Seawater heated by energy from the marine section on the base 10 is sent into the layer 2 including an energy transport route 18 to the base 10 from the marine section to the route 19. Alternately, an energy conversion device converting a part of the decomposition product gas into energy may also be installed to the base 10.

摘要： PROBLEM TO BE SOLVED: To provide mud flat and mud flat cover soil which sand crabs, etc., can continuously inhabit. SOLUTION: The cover mud is a mixture of clay, silt, and sandy soil, and has the grading with a uniformity coefficient (=D 60 /D 10 ) at which secure burrows of sand crabs, etc., can be formed, and the cover mud thus prepared is added to an inter tidal zone. Preferably, the uniformity coefficient of the grading of the cover mud is set to 20 or more. More preferably, the content of clay of the cover soil is set to 10% or more. It is desirable that the mixing ratio of the clay, silt, and sandy soil is adjusted to a range in which soil bearing strength for ensuring burrow security is obtained. For example, the mixing ratio of the clay, silt, and sandy soil is adjusted so as to have the soil bearing strength of 98.1 kPa according to the push cone method under the condition of moisture saturation. Further, it is desirable that the mixing ratio of the clay, silt, and sandy soil is adjusted such that the water content of the cover soil at the time of low water falls in a range of 20 to 60%.

摘要： PURPOSE:To enable continuous or dynamic measurement of three-dimensional displacement of swinging object to be made by determining camera parameters of two fixed cameras using four targets of a known position indirectly and by obtaining the position of a mark which is fixed to the swinging object from image coordinates of the mark using the camera parameters. CONSTITUTION:Position, slant, and focusing distance of two fixed cameras 9 are determined by image coordinates (x1j, y1j, x2j, y2j, j=1,2,3,4) of four targets on screens 101 and 102 of two cameras 9 for four targets whose position is known. A position (X, Y, Z) of a mark 3 is obtained from image coordinates (x1, y1, x2, y2) of the mark 3 on two camera screens 101 and 102 for the target 3 which is fixed to a swinging object 1. Then, a displacement of the swinging object 1 is calculated from fluctuation of the mark image coordinates (x1, y1, x2, y2) on the screens 101 and 102. Thus, since the displacement of the swinging object is calculated from fluctuation of the image coordinates of the mark, the displacement of the swinging object can be measured without any contact and continuously.

摘要： PURPOSE:To achieve vibration-free effect in a gravity-type ocean construction to be installed on a submarine surface, by separating a bottom part into a basse side bottom part and into a main body side bottom part, and for the horizontal external force of more than a predetermined value, by making contact surfaces of the base side bottom part and the main body side bottom part into contact with each other for slippery motion. CONSTITUTION:The lower bottom part of a hollowed construction main body 1 is separated into a base side bottom part 2 and into a main body side bottom part 3, and a dry partition 4 is provided in the center of the construction main body 1. Into the outside thereof, a water ballast 5 and a sand ballast 6 are injected or put, so as to make it a gravity-type construction. The contact surfaces of the base side bottom part 2 and of the main body side bottom part 3 is integrated with a base side bottom plate 2a and with a main body side slipper plate 3a that are made of stainless or of a Teflon processed steel plate, etc., on a concrete surface. When the horizontal external force of more than a predetermined value works, the construction main body 1 is slipped to the base side bottom part 2. earthquake energy is absorbed thereby and vibration-free effect can be obtained.

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.
