摘要： PROBLEM TO BE SOLVED: To provide the construction for preventing and stopping the generation of avalanche of sand and stone and capable of showing functions for preventing and stopping generation of avalanche of sand and stone for a long time without a concrete placing work. SOLUTION: A construction 1 for preventing and stopping generation of avalanche of sand and stone is formed by integrally connecting a downstream side square frame 2a and an upstream side square frame 2b through steel pipes 2c and H-shaped steels 2d, and a basket- like cylindrical body 2, from which these steel pipe 2c and the H-shaped steel 2d are projected out of the upstream side square frame 2b thereof, is continuously provided on the floor so that a lower surface of the downstream side square frame 2a of the upstream side basket-like cylindrical body 2 is arranged on the H-shaped steel 2d of the downstream side basket cylindrical body 2 and so that the projecting part of the steel pipe 2c of the downstream side basket- like cylindrical body 2 is arranged inside of the downstream side square frame 2a of the upstream side basket-like cylindrical body 2. Water included in the sand and stone layer piled in the periphery is drained, and water in the avalanche of sand and stone is drained so as to stop the sand and stone over a wide range. With this structure, functions for preventing and stopping generation of avalanche of sand and stone can be showed for a long time without placing concrete.
