摘要： PROBLEM TO BE SOLVED: To improve controllability of a laying work at a seashore by a method wherein a flexible bag body is filled with soil and gravels, serving as a filler and the bag body is combined with a cage frame body made of a steel. SOLUTION: A flexible bag body formed of a net made of synthetic resin is filled with a filler comprising one or two or more kinds of crushed stone, gravel, and soil and the flexible bag body is contained in a cage frame body made of a steel having rigidity. The cage frames are arranged in a direction crossing the beach line of a sand beach and a number of cage frame bodies are buried in a continuous or a discontinuous state. A reinforcement cage l is conveyed to a laying site in such a state that the coupling sides of a reinforcement net having six surfaces containing a cover are bendably coupled together by means of coils 4. After a bag body 3 conveyed in such a state to be previously filled with a filler 2 is placed on the reinforcement net being the bottom of the reinforcement cage 1, the bag body is coupled to a remaining five-face assembly and an upper surface cover is set to complete the reinforcement cage 1. Since fillers having different grain sizes are served as a filler, a water permeable bed suitable to a laying side is built.

摘要： PURPOSE:To efficiently drain wave going upstream and ground water by inclining a large number of drain structural bodies between the position above the position of wave going upstream and the required deep water position to bury and arrange them as surfaces. CONSTITUTION:A filter member 42 having permeability and preventing the incursion of sand 20 is stretched to the outside of a flat shaped main body 38 formed of a frame body, and drain structural bodies 30 forming a drain space 44 extended in the horizontal direction are provided to the inside thereof. After that, the drain structural bodies 30 are inclined between the proper position A above the position of wave going upstream in a beach 14 and the required deep water position B, and a large number of drain structural bodies 30 are connected to bury and arrange them as surfaces. Wave going upstream and ground water raising the water level in sandy soil of the beach 14 are discharged into the sea through the drain structural bodies 30, and the ground water level is lowered to stabilize the beach 14.

摘要： PROBLEM TO BE SOLVED: To provide a construction method of a drainage layer in a stabilizing method of a sandy beach in which erosion in a sandy beach caused by waves is restrained and accumulation of sand is accelerated. SOLUTION: The construction of a drainage layer is constituted of a stage in which a sandy beach 1 such as a seacoast or the like is excavated to form an excavation zone 3, a stage in which a retaining water-impermeable sheet 7 for crushed stones having an extra length 7a necessary for connection is laid in the excavation zone 3, a stage in which crushed stones 5 are placed onto the retaining sheet 7 for the crushed stones in the excavation zone 3, and a stage in which the upper face of the crushed stones is covered with the extra length 7a of the retaining sheet 7 for the crushed stones after the crushed stones 5 have been completely fed in the excavation zone 3 and the superposed parts are joined together and further, the upper face is covered with sand.

摘要： PROBLEM TO BE SOLVED: To provide a method for manufacturing a hollow concrete block which enables the amount of concrete to be used to be saved significantly and has a sufficient strength through a simple means and in an easy way. SOLUTION: A baglike member 6 which can be inflated by filling the member 6 with a fluid such as air internally, is arranged in a form after preparing it. Next, concrete is formed into the form and the fluid packed into the baglike member 6 is discharged after curing and hardening. Thus the baglike member 6 is unloaded from the interior of the concrete to form a cavity part inside the concrete.

摘要： PROBLEM TO BE SOLVED: To provide easy quality control for a concrete block by blocking both opposite sides of a frame material, arranging an artificial stone panel designed as a false stone masonry on the front side face and a water-permeable concrete on the rear side face and providing a packing material filling area in the frame body. SOLUTION: Both opposite sides of a concrete frame body 12 formed into almost rectangular parallelopiped are blocked by concrete panels 14. The front side face of the frame material 12 is formed as an slope, where an artificial stone panel 18 designed as a false stone masonry with cavities 16 to form a number of stone large and small vent holes is arranged. A panel 20 formed with a water-permeable concrete is arranged on the rear side face. The inside of the frame material 12 for a revetment block 10 formed in this way is constructed as a filling area 24 for packing materials such as packing stones 22.
