摘要： PURPOSE:To make the construction of a retaining wall easier by a method in which the plate portion of a bag structure formed by connecting a flexible bag to a plate material is erected on the foundation ground, cement mortar is packed into the bag structure, and the bag structures are stacked up in a multistage in order. CONSTITUTION:A flexible bag 5 made of a high-strength cloth is connected to one side of a plate material 2 having a fitting portion 3 on its upper end to form a bag structure. The plate 2 portion of the bag structure is erected on the foundation ground and fixed at a design angle, and cement mortar or concrete 4 is packed into the bag 5. The plate 2 of the bag structure to be used in the second stage is fitted into the fitting portion 3 of the first stage plate 2, and concrete 4 is packed into the bag 5. The bag structures are stacked up in multistages in a repeated manner to construct a retaining wall.

摘要： PURPOSE:To prevent a water stopping function from weakening even when an anchor pin is driven, by interposing a cap filled with an inorganic material swelling by absorbed water between the head of anchor pin and the impervious sheet. CONSTITUTION:A cap 4 is made of a steel plate or synthetic resin to form a hemisphere for instant. In this cap 4, a water-absorptive swelling inorganic granular material like bentonite, for instance, is charged without voids by use of an adhesive. After an impervious sheet 3 including the water-absorptive swelling inorganic material 1 is laid down, the cap 4 is placed at the position where an anchor pin 5 is required. The anchor pin 5 is driven until the head gets in contact with the cap 4. At this time, a setting metal 10 may be used in order to prevent the cap 4 from swelling. The bentonite or the like within the cap 4 is forced to absorb water and swell and an adhesive restricting it is made colloidal to fill the anchor hole and secure the impervious property.

摘要： PURPOSE:To form a pile capable of having high bearing forces in a short curing time by a method in which a water-permeable cloth cylinder having a different (in lengthwise direction) lateral expandability is penetrated into the ground and a hydraulic slurry is injected into the cylinder. CONSTITUTION:An excavation pit 1 of less than a given diameter is formed beforehand having lateral expandability in lengthwise direction and a top-closed water-permeable cloth cylinder 2 is inserted into the pit 1. A hydraulic slurry 5 is injected under pressure into the cylinder 2 through its upper open end 4 and the excess water of the slurry 5 is removed through the cloth of the cylinder 2 to form a hardened hydraulic block 7. A foundation pile having a different (in lengthwise direction) cross sectional form can thus be obtained, giving high bearing forces.

摘要： PURPOSE:To bond a water-barrier sheet susceptible to simple and rapid execution and capable of obtaining sufficient cut-off capacity. CONSTITUTION:Water-barrier sheets 4, 4' are laid on a foundation in a mutually abutted state and a striplike bonding sheet 5 having a layer composed of a water absorbable and swellable inorg. substance 2 provided on the under surface thereof is arranged and fixed to the water-barrier sheets 4, 4' along the upper surface of the abutted place of said sheets 4, 4' to form a bonded part. The bonded part thus formed is covered with soil and the water absorbable and swellable inorg. substance is hydrated and swollen to add water in order to integrate the bonded part. By fixing the particles of the water absorbable and swellable inorg. substance between water permeable sheets by an adhesive and arranging and fixing the striplike bonding sheet 5 along the upper surface of the abutted place of the water-barrier sheet showing flexibility, the execution of the bonded part can be simply and easily performed and the cut-off capacity of the bonded place can be sufficiently ensured.

摘要： PURPOSE:To facilitate execution by forming a cylindrical body with a flexible sheet which possesses self-standing and dewatering properties, rigidly fixing the body on a bar-shaped supporting body and folding back the lower end of the cylindrical body inward before placing concrete. CONSTITUTION:A cylindrical body 1 is formed with a flexible sheet possessing self-standing and dewatering properties, and arranged in a way to surround a foundation 5 built by arranging reinforcing bars. The cylindrical body 1 is made into one body with a bar-shaped supporting body 2 reinforced with a bar-shaped body 7, using fixing metals 3. Next, the lower ends of the cylindrical body 1 are folded back inward to have turn-up parts 8 and concrete is deposited from the open end on top of the cylindrical body 1. This makes the execution of work easy and speedy.
