摘要： PROBLEM TO BE SOLVED: To provide an impervious wall method excellent in the long term stability of impervious performance.
SOLUTION: A casing 3 is pierced to a predetermined position by pressing the casing and excavating the inside of the casing, a predetermined amount of bentonite mixed soil 1 is thrown in an excavated hole, the casing is pulled out up to a predetermined height, the bentonite mixed soil thrown is compacted, the throwing of the bentonite mixed soil, the pulling out of the casing and the compaction are repeated to construct a pile body 2 formed of the bentonite mixed soil with a predetermined length, and the construction of the pile body is repeated to form a method constructing a wall body 20 in the ground by continuing the pile body. In order to ensure a homogeneous physical property over the overall length of the pile body and integrity with the peripheral ground, the bentonite mixed soil is thrown by a proper amount so as to be sufficiently compacted to carry out compaction.

摘要： PROBLEM TO BE SOLVED: To provide a method and a system for removing sediment from a dam, which enable the removal of the sediment with a large grain size, and which hardly cause a rise in a river bed of a river downstream from a dam body.
SOLUTION: This system 1 for removing the sediment from the dam, which removes the sediment (sediment T) accumulated in the dam storage reservoir L of the dam D constructed in the river R, comprises: a dredger 2 which serves as a sediment sampling means for sampling the sediment T; sediment conveying equipment 3 for conveying the sediment T from the dredger 2; a sediment crushing plant 4 which serves as a sediment crushing means for crushing the sediment T; and fine-sand conveying equipment 5 for conveying fine sand S to a planned sediment area A which is provided directly upstream of the dam D from the plant 4.

摘要： PROBLEM TO BE SOLVED: To facilitate boring for grout working and make a stiff structure by using a grout pipe for at least a part of frame material for continuos underground wall construction. SOLUTION: A frame skeleton is constituted of a dry excavation frame skeleton 1 and a body part flame skeleton 2. The dry excavation part frame skeleton 1 is used in a case where the construction planned ceiling end of a continuos underground wall is lower than the site ground. The body part frame skeleton 2 is a frame skeleton which is the body part of the continuos underground wall, is composed of a frame material 3 as a main girder, inclination material 4 connecting the frame materials 3, and a horizontal material 5 for horizontally connecting the frame materials 3. A part or the whole of the frame material 3 is constituted of a grout pipe with a bottom cover composed of a thin iron plate, after construction of the continuos underground wall the frame material 3 is used to perform grout in the foundation bedrock of the continuos underground wall edge. A partition iron plate 6 is integrally framed with the horizontal material 5 on both the ends of the body part frame skeleton 2.
