摘要： PROBLEM TO BE SOLVED: To prevent liquefaction of weak ground by having a plurality of circular-arc gravel drains connecting respective base ends to a gravel shaft and its lower part. SOLUTION: In the neighborhood of a structure 1, at least one small-sized shaft 4 is excavated until a bottom part reaches the layer of earth 2 having possibility of liquefaction. Next, excavation is performed by a circular-arc pipe jacking method as a circular-arc hole 5 extending to the layer of the earth 2 from the lower part of one shaft 4 reaches the other shaft 4, and respective circular-arc holes are filled with gravel. The gravel is charged into the shaft 4 to be filled. Thereby a plurality of circular-arc gravel drains 6 can be installed in the layer of the earth 2. Since excessive gap water produced in an earthquake is quickly drained on ground through the gravel shaft of both the gravel shafts from each circular-arc gravel drain 6, the liquefaction of the layer of the earth 2 can be prevented. In addition, since the gravel shaft can be installed near sideward of the structure 1, a ground occupying area can be lessened.

摘要： PROBLEM TO BE SOLVED: To provide an agitating truck for mixing earth and sand together, which dispenses with special facilities, and is free from clogging of earth and sand and degradation in ability to produce mixed earth and sand, and to provide a method for throwing the mixed earth and sand using the agitating truck. SOLUTION: The agitating truck 10 for mixing earth and sand is constituted by arranging a funnel-like earth-and-sand charging portion 1 on a hopper 12 of a mixer drum 11, forming a water filler 2 for feeding water in the earth-and- sand charging portion, and setting an earth-and-sand introducing portion 4 for introducing earth and sand from the earth-and-sand charging portion into the mixer drum. The method for charging the mixed earth and sand by using the agitating truck thus constructed, has the following steps. In the first step, earth and sand, water, and a hardener are charged into the agitating truck in a charging field. In the second step, the charged earth and sand, water, and hardener are conveyed to a charging position while being mixed together. In the following step, the mixed earth and sand are discharged from the agitating truck and then thrown, in the throwing site.

摘要： PROBLEM TO BE SOLVED: To simultaneously accomplish the prevention of liquefaction of the ground when an earthquake occurs and the reinforcement of the ground, and to effectively use resources. SOLUTION: A material having grain size within a usable range as a drain material among materials selected by the grain size is used as gravel drain piles 1 developed/arranged in the ground at specific intervals. Other material having grain size within a range other than that is used as compaction piles 2 developed/arranged in the center sections or around the gravel drain piles 1.

摘要： PROBLEM TO BE SOLVED: To reduce vibration and dust upon withdrawal so as to easily remove a concrete extra banking part by attaching a member to be buried, composed of a spherical members which can float in water, and which are connected together by means of wires, to the internal reinforcing bars in the concrete extra baking part, and by removing the extra banking part after concrete cast into the extra banking part is solidified. SOLUTION: A member A to be buried, is composed of spherical members 1 which can float in water, and wires 2 connecting the former. For example, when an extra banking part of a concrete pile which is built in the site is processed, the member A to be buried is fastened by a fastening wire 5 to the head part of an internal insertion reinforcing steel cage 4 after an excavated hole 3 for the concrete pipe is formed, and the reinforcing steel cage 4 is built in the excavated hole 3, and concrete 6 is placed. At this time, the member A to be buried floats in the concrete. Finally, the extra banking concrete 7 is removed. In this case, by setting the distance between the spherical members 1 and the side surface of the concrete pile to be small, and accordingly, the chipping of a thin covering concrete and the destruction of the spherical member body can be facilitated, thereby it is possible to simply remove the extra banking.
