摘要： PROBLEM TO BE SOLVED: To provide a method for positioning of a core material for a soil- cement column-row wall, which allows the core material to be positioned in an excavated hole, filled with soil cement, with a higher accuracy. SOLUTION: A solidifying material is injected for mixing while ground is excavated and agitated in a columnar shape; and columnar bodies, which are formed by solidification of solidifying-material mixed sediment, are disposed for construction, so that the soil-cement column-row wall for being installed underground can be constructed. In this case, after the injection and agitation of the solidifying material, the guide device 10 for the positioning of the core material, which is long enough to reach a desired depth, is inserted into the excavated hole 1 from an opening thereof, so as to be fixed in the excavated hole 1 at a prescribed angle; and the core material 2 is inserted so as to abut on the guide device 10.

摘要： PROBLEM TO BE SOLVED: To provide a construction method for an underground structure by a PCa pile underground wall to construct the underground structure at less cost in a short period of time by less site work and safely without disturbing a ground in the circumference. SOLUTION: PCa pile underground walls 1 are arranged opposed to each other or in a ring by driving a large number of precast concrete piles underground by arranging them in a row. Thereby, a top plating 2 is constructed with cast-in-place concrete integrally with an upper end of the underground wall in a state of primarily drilling between the underground walls 1, 1 to depth where a top part of the underground wall 1 is exposed, and a bottom plating 3 is constructed with cast-in-place concrete after drilling and forming an underground space between the underground walls 1, 1 by primary drilling.

摘要： PROBLEM TO BE SOLVED: To prevent damage of an underground wall wherein PCa piles made of prestressed concrete are used, couple more strongly with a floor slab, and decrease man-hours of working in the site. SOLUTION: When floor slab is integrally formed with a side wall 1 which consists of a PCa pile underground wall installed to arrange a lot of hollow pipe shape precast piles 10 in the underground by cast-in-place concrete, a steel plate 16 for connecting the floor slab is provided on a height position for connecting the floor slab of a side surface of the precast pile 10, and plate shape anchors 20 which face vertically are integrally provided on both side parts of a back of the plate 16. The plate shape anchors are passed between PC steel materials for introducing prestress which is built in the precast pile 10 and between reinforcing bars when they are incorporated to bury in a wall thickness, thereby the plate 16 is integrally formed with the pile 10, and the floor slab reinforcing bars are integrally formed with the plate 16.

摘要： PROBLEM TO BE SOLVED: To continuously treat a large amount of mud by providing a plurality of sludge storage and dehydration beds and supplying sludge to one or more of the beds from mud suctioning facilities during the time when sludge stored in the rest of the beds is being settled and dehydrated. SOLUTION: In this equipment, mud suction facilities 2 are placed on the bottom of a river or lake 1 and sludge collected within the mud suction facilities 2 is transferred to a confluence pipe 5 through a sludge recovery pipe 3, with air from a compressor 4 and there, a part of drainage of the sludge is discharged with a water discharge device 6 and the residual sludge is accumulated in a storage facilities 7 formed underground. The storage facilities 7 comprise a tank that is divided into two vessels, i.e., left and right sludge storage/dehydration vessels 9 and 10 by a partition wall 8 and each of the sludge storage/dehydration vessels 9 and 10 consists of an upper sludge storage section and a lower drainage chamber 12, both of which are partitioned from each other by a dehydration bed plate 11. The sludge supplied from the confluence pipe 5 is stored in one of the two vessels 9 and 10, and while the settling, dehydration and discharge treatment of the sludge in this vessel 9 or 10 are performed, the sludge is stored in the other vessel 10 or 9. Thereafter, this operation is repeatedly performed.

摘要： PROBLEM TO BE SOLVED: To form a void space having the maximum size necessary for immersion joint between preceeding and following caissons, fill a tapered space between slopes on the end faces of side walls with mortar, cope with high earth and water pressure by a simple earth retaining wall so that working load from the outside is directly borne on caisson side walls and to reduce a construction cost and a construction period of time for that purpose. SOLUTION: This underground structure-constructing caisson is projected to the end faces on side walls 1 and 2 of the caisson in a V-shape having the top in a position rectified to a bedrock side. A proceeding caisson is immersed in the ground. Then, a steel plate 16 extending across the end face is mounted to the bedrock side of a following caisson having the same shape of the end face as that of the preceeding caisson, while interlocking the steel plate 16 with the bedrock side of the preceeding caisson so that it is adjacent to the preceeding caisson through a specific space 3, the following caisson is immersed in the ground, an inside frame is erected from the bedrock side in order to close the space 3 formed between the tops in a slope 13c on the end faces of the preceeding and following caisson side walls 1 and 2, mortar is placed in a space 18 formed between the outside slope of the end faces on the preceeding and following caisson side walls 1 and 2 and inside frame 17 of the bedrock, the preceeding and following caisson side walls 1 and 2 are connected with reinforcement 4 between the inside slopes of them, and joint concrete 20 is placed between the end faces of the preceeding and following caissons.

摘要： PROBLEM TO BE SOLVED: To improve constructibility by preventing a traffic hindrance from being caused by the interruption of an upper road and by dispensing with carrying-in/carrying-out and temporary placement of a large amount of sediment in removing an underground installation while a construction range is reduced without requiring construction of large-scale cofferdam revetment in embankment work.
SOLUTION: The underground installation 2 is enclosed with a cylindrical body 8 having a cross section including the underground installation 2. The demolition of the underground installation 2 and the excavation and removal of the sediment are performed in the cylindrical body 8, while the cylindrical body 8 is advanced underground from a starting shaft 9. After the cylindrical body 8 reaches an arrival shaft 10, a void after the movement of the cylindrical body 8 is backfilled while the cylindrical body 8 is returned to the side of the starting shaft 9.
