Description
【発明の詳細な説明】 （産業上の利用分野） 本発明は河川、貯水池、造成地等における法面の保護
方法に関するものである。TECHNICAL FIELD The present invention relates to a method for protecting a slope in a river, a reservoir, a constructed land, or the like.
（従来の技術） 従来、法面の保護方法として、例えば遮水を目的とし
て法面にゴム系や塩化ビニル系の遮水シートを敷設し、
この遮水シートの上に順次擁壁ブロックを設置する方法
がある。(Prior Art) Conventionally, as a method of protecting the slope, for example, a rubber-based or vinyl chloride-based waterproof sheet is laid on the slope for the purpose of blocking water,
There is a method of sequentially installing retaining wall blocks on this water blocking sheet.

る。(Problems to be Solved by the Invention) However, in such a conventional method for protecting a slope, since the retaining wall block is simply installed on the water-impervious sheet placed on the slope, water blocking at the time of installing the block is prevented. There is a problem that the sheet is hit by the wind, and the block sheet is slackened or wrinkled when the block is moved, which hinders the block installation work and reduces workability. Also, regarding the laying of the water blocking sheet,
A large number of water-blocking sheets of a predetermined size must be bonded and laid one after another at the site, and the workability is poor.

擁壁ブロックを設置するものである。(Means for Solving the Problems) In order to solve the above problems, the method of protecting the slope of the present invention is
A primer is applied to the slope that is almost smooth, and then a water blocking material consisting of polymer mortar cement or synthetic resin is applied and cured to form a water blocking layer, and retaining wall blocks are sequentially installed on it. Is.

ン等の合成樹脂ネットが使用される。In the method of the present invention, a primer layer (2) is first formed by applying a primer to the sloped surface (1) having a substantially smooth surface. The primer is generally applied by spraying, but other methods may be used. Then, a reinforcing net (3) is laid on the primer layer (2). The reinforcing net (3) is for reinforcing the water-impervious layer (4) and is not necessarily required, but is preferably laid. As the reinforcing net (3), a synthetic resin net such as glass fiber, vinylon, polypropylene, polyethylene, nylon, or tetron is used.

As the water-blocking material, polymer mortar cement is preferable in terms of water-blocking property, adhesiveness, flexibility, tear strength, etc., but epoxy resin, urethane resin, MM
A resin, a synthetic resin such as vinyl chloride sol may be used. A spraying method is generally suitable as a method of applying the water-blocking material, but it may be applied by rake work, plastering work, brush work, or the like. Then, the retaining wall blocks (6) may be sequentially arranged on the water-impervious layer (4). At this time, if aggregates or sand (5) are sprayed on the water-impervious layer (4), it is easy for the worker to work safely on the water-impermeable layer (4) when the block (6) is installed. preferable.

させることができる。(Effects of the Invention) As described in detail above, in the method for protecting the slope of the present invention, after the primer is applied to the slope, the water blocking material is applied and cured to form the water blocking layer. There is no need for the impermeable sheet to be exposed to wind as in the method of using, and slack or wrinkles do not occur on the impermeable sheet, and the retaining wall block can be easily installed on a stable impermeable layer. Installation workability can be improved. Further, since the water-impervious layer and the slope are adhered, the durability can be improved as compared with the conventional water-impervious sheet simply placed on the slope. Further, since the water-impermeable material is applied and cured to form the water-impermeable layer, the workability of construction can be improved as compared with the conventional connection of the water-impermeable sheet.
