摘要： PURPOSE:To make the construction of cut-off wall or zone for fill dam easier by forming the cut-off wall or zone of expanded styrol blocks for the fill dam. CONSTITUTION:The core zone (c) of a fill dam is formed by stacking up expanded styrol blocks in a trapezoidal form, and the styrol blocks are connected with each other by using a vinyl acetate-based adhesive, a butyl rubber-based double-side adhesive tape, or a connector (dowel). A filter zone (b) and a lock zone (a) are constructed on both sides of the zone (c). The construction of the cut-off wall or zone can thus be easily performed because of the high water shielding property and the small specific gravity of the expanded styrol.

摘要： PURPOSE:To prevent the adhesion of mortar to the inner wall surface of a nozzle, by providing a gap between the outer peripheral end edge of an expanded annular body and the inner peripheral of an emitting nozzle and communicating the space provided between the expanded annular body and the enlarged part of an inlet cross-section with the open air. CONSTITUTION:The coating material flowing in a nozzle main body 3 from a pipe 1 flows as shown by an arrow A by the action of an expanded annular body 4 without being formed into a turbulent stream and is decelerated by the cross-sectional expansion effect of said annular body 4. In this case, the air entering a space 6 through an opening 7 flows from a gap 5 along the inner surface of the nozzle main body 3 as shown by an arrow B to form an air layer. Therefore, a phenomenon of generating clogging by the adhesion of mortar to the inner wall surface of the nozzle can be prevented. The coating material properly decelerated in the nozzle main body 3 is emitted to the outside as almost parallel flow as shown by an arrow C by the throttling effect of an outlet side 3c.

摘要： PURPOSE:To easily and exactly settle a caisson by a method in which the ground is drilled and agitated by a drill for a neccesary part of planar projection area for a caisson body and the caisson body is set on the ground. CONSTITUTION:The ground 1 is drilled to form a hole 3 and agitated by an excavator, e.g., drill, etc., for a necessary part of planar projectional area A for a caisson body 2. The caisson body 2 is settled on the ground 1. Since the bearing strength of the ground 1 can be lowered, the caisson body 2 can be smoothly settled into the ground 1.
