Multi-stage staircase combined immersion prevention structure in the environment where fish, amphibians or reptiles are easy to live by the structure of multi-stage stairs using stone box in river or river reservoir

摘要

The design of the present invention is to construct a lake-like staircase reservoir using a stone pit in a river or river, to create a nature-friendly reservoir for the habitats of fish, amphibians, or reptiles. Is to devise a staircase.;The role of the reefs in protecting rivers and acting as spawning places or habitats for fish, amphibians or reptiles in the rivers, while protecting reservoirs in order to protect the banks of rivers and streams, and to form waterways. It is designed to construct a nature-friendly multi-level stairway to build a reservoir with the same time.;Conventionally used waterway construction methods include stonework using concrete retaining wall or crushed stone and woodworking. These methods are not suitable for the natural river environment and also waste a huge budget because of the short life of wood. It was not uncommon for people who used to swim in the rivers or skate in the winter to pluck wood and set fire to cope with the cold.;Also, when the fire was set to burn the pampas grass growing in the blunt, the wood burned.;In addition, there are methods to build retaining walls by forming stone masonry using stone blocks. This method also built retaining walls at right angles rather than stairways, which resulted in frequent drowning accidents of people playing around the waterway. This resulted in the loss of habitats for living creatures in the rivers.;In the case of the concrete retaining wall method, the retaining wall was constructed to be close to the right angle, so that it was not effective as a staircase, and reptiles and amphibians, such as snakes and frogs, once fell into the reservoir, often failed to crawl out.;In the present invention is a configuration devised in view of these problems.;This paper is organized as follows.;A series of stone boxes composed of rectangular or square shapes in the form of a stone box formed by putting the stones properly in a state in which stainless steel or corrosion-resistant wire rods are stacked vertically and horizontally so as to form a rectangular box. As a shape of a water reservoir formed to be a multi-step staircase, it is a method of forming a multi-step staircase by laying a predetermined thickness of concrete or laying a vinyl film or sheet on a top of a stone box.;The effect of the present invention is configured as follows.;If a multi-level staircase is formed by using the components of the present invention in the reservoir, there is an effect of fish that serves as a shelter and a spawning place for fish in the part facing water, and because of the effect of the multi-step staircase It is possible to prevent drowning accidents of water players in close proximity.;It is a beneficial design for ecosystem restoration because it does not interfere with the movement of amphibians and reptiles that alternate between water and land.;In addition, by the support of the multi-level stone box is to protect the banks to the reservoir.
