摘要： PURPOSE:To set a vibration-isolating bearing for bridge separately from dampers by a method in which a laminated rubber layer is provided between the upper and lower shoes facing the superstructure, rollers are set between the lower shoe and a bottom slab facing the lower structure, and a high vibration-damping rubber is fixed to them. CONSTITUTION:A laminated rubber layer 3 to absorb the turning force of the superstructure is provided between an upper shoe 1 facing the superstructure and a lower shoe 2 under the shoe 1. Rollers 5 to support the superstructure in an axially rocking manner are set through a distribution plate 6 between the lower shoe 2 and the bottom slab 4 facing the lower structure. A high- damping rubber 8 is also fixed between the lower shoe 2 and the bottom plate 4. The natural frequency of the superstructure can thus be lengthened by the spring effect 12 of the rubber layer 8 and the displacement of the structure can be lessened by the damping force. The vibration in the axial direction of the bridge can therefore be isolated.

摘要： PROBLEM TO BE SOLVED: To enable GPS surveys even when there is a high obstruction around a survey point by calculating the coordinates of an antenna mount, which is connected to the hoisting and lowering part of a vehicle for high lift work, using GPS radio waves, and specifying the coordinates of the survey point from the coordinates of a reference point vertically below the calculated coordinates of the antenna mount. SOLUTION: An antenna mount 2 is mounted on the tip of the boom 4 of a vehicle for high lift work 3, and the boom 4 is extended up to a height where surrounding woods 13 may not obstruct the reception of radio waves from GPS satellites 10. Then a rotating prism 6 placed at a reference point is removed, and the mount 2 is positioned at a location directly above the reference point. Next, the coordinates of the mount 2 is calculated through the use of GPS radio waves received by a GPS antenna 9 and a GPS controller 12, and the vertical distance between the mount 2 and the reference point is found by a light wave range finder. Next, the rotating prism 6 is mounted to the location of the reference point to find the coordinates of the reference point by deducting the vertical distance from the vertical coordinate components of the mount 2, and through the use of the found coordinates, the coordinates of a survey point 11 is measured.

摘要： PURPOSE: To reduce auger torque at the time of drilling due to a friction reducing effect, to improve earth removal efficiency, or to sufficiently reduce resistance at the time of erecting a precast pile in a bored precast pile construction method using mechanical drilling, whereby a precast pile can be buried and installed in the ground quickly and efficiently. CONSTITUTION: An earth auger 4 is lowered while being rotated to drill the ground E, and a bubble manufacturing plant 8 is operated concurrently with the above operation, whereby bubbles generated by a bubble generator 14 are ejected from the tip of the auger 4 through a swivel joint 6. The bubbles obtained by mixing air with an aqueous solution of water-soluble high polymer are different from the conventional bubbles obtained by using a surfactant or the like, and though the expansion ratio of the obtained bubbles is low, the tackiness and gravity are large so as to effectively reduce frictional resistance between soil particles, or between the soil particles and the earth auger 4 or a precast pile 20. Thus, the auger torque at the time of drilling can be reduced, and the earth removal efficiency can be improved, or the resistance at the time of erecting the precast pile 20 in a drilled hole 30 can be reduced sufficiently.
