摘要： PROBLEM TO BE SOLVED: To prevent deformation of an anchor plate equipped with a drainage material when the drainage material is driven in a hard ground by widening the front end of a mandrel so as to come into close contact with the V-shaped inside face of an anchor plate holding a fixing plate of the drainage material at the intermediate position of the height direction. SOLUTION: This driving equipment is constituted of an anchor plate 3 provided with a V-shaped sectional shape and a fixing member 4 at the intermediate position in the height direction and a mandrel 1 obliquely cut so as to bring the widened front end into close contact with the V-shaped inside face of the anchor plate 3. When a drainage material 2 is driven, the end of the drainage material 2 set in the mandrel 1 is fixed to the fixing member 4 of the anchor plate 3 and then, the front end 7 of the mandrel 1 is brought into close contact with the V-shaped inside face of the anchor plate 3 to insert the mandrel 1 into a specified depth of the ground 6. Only the mandrel 1 is pulled out of the ground but the anchor plate 3 is left in the ground as the front end of the drainage material 2 is fixed and hence, it functions as an anchor.

摘要： PURPOSE:To make correction of non-land portion of a rubble surface unnecessary and realize construction at a servere wave condition place and improve work efficiency by conducting simultaneously rubble throw-in and its top face levelling. CONSTITUTION:A tremie pipe 4 is provided on a travel truck 50 on a rubble supply ship 2 through a universal joint 5. Also, a scattering preventing skirt 12 of a cylindrical shape made of rubber is fitted to the lower portion of the tremie pipe 4, and right under this, an levelling robot 3 having a hopper 13 whose positioning movement is free, and a chute 14 to make rubbles from the hopper 13 flow out to the water bottom, is provided. Herein, the hopper 13 and the tremie pipe 4 lower portion are not connected to each other, and constitution is made so that a robot 3 motive power cable 25 alone is connectable to the rubble supply ship 2. Under the condition of the ship 2 being moored by means of plural wire ropes 1, rubbles are thrown in through a hopper 6 and introduced into the hopper 13. Simultaneously, the robot 3 is made to travel on the water bottom, and rubbles are made to flow out of the chute 14 while the chute 14 is being moved horizontally.

摘要： PROBLEM TO BE SOLVED: To force a casing to penetrate a ground such as the periphery of an existing oil tank, which a large heavy construction machine can not enter, by use of a small boring machine or the like and drive a drain member to prevent the liquefaction of the ground. SOLUTION: After a drain member 1 equipped with an anchor plate 2 at one end thereof has been inserted in a casing 5, the drain member 1 is inserted into the ground G together with the casing 5 by a driving machine 6. And the casings 5 and the drain members 1 are additionally connected to insert them to a specified depth of the ground. And then, water is poured into the casings 5 and only casings 5 are drawn out of the ground G and then, the periphery of the drain members is filled back.

摘要： PURPOSE:To exactly enhance the efficiency of leveling and compacting operations by a method in which two groups of four travel legs expandible to the lengthwise direction are attached to a base frame in such a way as to enable them to travel to different directions and a leveling weight is allowed to move vertically. CONSTITUTION:Two groups of four travel legs expandible to lengthwise direction are attached to a base frame 2 through a pin-supporting point 3 enabling then to travel in 90 deg. different directions from the legs of each group. A travel- drive jack is operated to enable them to move to all directions. A weight 6 is also provided on the center of the base frame 2 in a such a way as to permit it to move vertically. The leveling operation of rubber mound can be effectively raised without affected by the waves or weather of sea.
