摘要： PURPOSE:To improve work efficiency and to shorten a construction period to reduce a cost by manufacturing hollow elements having a shape of slitting a marine construction in the case of completion, boring pile guide holes in them and providing joint holes on both sides of each of them. CONSTITUTION:Hollow elements 2 with a floating body construction having a shape of splitting a marine construction in case of completion and having pile guide holes bored in them as well as forming joint holes 6 on both sides of each of them are manufactured, and they are towed to installation places to pour water into the hollows from a water supply hole 7 until they reach near to neutral buoyance, then they are temporarily landed on the sea-bottom. After that, the adjacent elements 2 are temporarily connected to each other with a joint member 5 lying across the joint holes 6, and bearing piles 15 are driven from the pile guide holes 4 to fix the elements 2. According to the necessity, water or filler is filled into the hollow and, at the same time, mortar 16 is filled into the joint holes 6 by means of a grouting and the like, and the whole is stabilized to complete the marine construction.

摘要： PURPOSE:To be not influenced by the depth of water, to have a simple construction to make execution and repairement easy and to reduce a construction period by binding ends of a plurality of anchoring ropes respectively to fasten outstanding piles driven to the sea bottom and floating body on the surface of the water. CONSTITUTION:One ends of a plurality of anchoring ropes 23 of a material with high corrosion resistance are fixed to a floating body 20 provided in the vicinity of the surface of the water on which wave energy is focussed through fasteners 26. After that, the other ends of the anchoring ropes 23 are hung and installed in the vertical direction or downward on the slant to bind them to the upper ends 24a of a plurality of outstanding piles 24 driven to the sea- bottom 25 in advance through a separate fastening metal fittings respectively, and the floating body 20 and outstanding piles 24 are fastened to form a multi- pile type floating breakwater. The variation of the floating body 20 is constrained to absorb wave energy, and there is no fear of settlement, so that it is not influenced by the depth of water by changing the free lengths of the outstanding piles 24.

摘要： PURPOSE:To accurately judge whether or not the drilling direction of a hole is on a perpendicular line by providing a drill pipe which is driven to rotate, a cutting means which is fixed to one end part of the pipe, and inclinometers fitted to one end part of the drill page. CONSTITUTION:While the hole 16 is drilled, both inclinometers 28 receive equal centrifugal force generated by the rotation of the drill pipe 12 on condition the axis of the drill pipe 12 is perpendicular and output an equal value. When the axis of the drill pipe 12 is not perpendicular, on the other hand, both inclinometers 28 slant together wit the drill pipe 12 and the output values of both inclinometers 28 are different. It is confirmed whether or the drill pipe 12 is perpendicular, namely, whether or not the hole 16 is drilled perpendicularly by checking whether or not the outputs of both inclinometers 28 is equal.

摘要： PURPOSE:To measure the quantity of deflection angle and the quantity of deviation of an excavator with respect to a tunnel by arranging the 1st and the 2nd ray generating means in the rear from the excavator in the tunnel and measuring the position of the excavator from output signals of the 1st and the 2nd television cameras. CONSTITUTION:At the time of excavating, a ray transmission part 16 of a position measuring instrument 10 points the 1st and the 2nd rays 36 and 42 in parallel with the axis of the tunnel 12 in the direction of the excavator 14 by the 1st and the 2nd ray generating means 26 and 28 and the distance between the ray transmission part 16 and a photodetection part 18 is measured by a range finder 30 and its measured value is supplied to a control part 20 via a relay part 22 as a distance signal. In this way, the 1st ray 36 is made incident on the 1st photodetector 58 and the 2nd ray 42 is irradiated on a screen of the 2nd photodetector 62. The photodetection part 18 picks up the 1st ray generating means 26 on image by the 1st television camera 72 and a clinometer 106 measures an angle of rotation of the excavator 14 and supplies a measured value to the control part 20 via the relay part 22. The control part 20 calculates the quantity of deviation and the quantity of deflection angle of the excavator 14 with respect to the tunnel 12.
