【発明の詳細な説明】
本発明は土砂又は軟岩等で形成されている法面の安定と
緑化とを図る法面緑化工法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a slope greening method for stabilizing and greening slopes formed of earth and sand or soft rock.

状である。Traditionally, as a means of sowing plant seeds on slopes for greening,
It is known to spray seeds directly onto the slope, or to drill a large number of holes in the slope and then spray the seeds, but this is especially true when the slope is made of clayey soil or soft rock with unclear joints. At present, when the slope is green, seeds are washed away by rain and gully erosion occurs, making it extremely difficult to reliably green the slope.

要となる。In addition, in order to introduce greening while preventing partial sliding collapse of long slopes, a hard structure that can withstand sliding stress is required.

植物種子を播種することを要旨とするものである。In view of these current circumstances, the present invention is a slope greening method that simultaneously stabilizes the slope and revegetates the slope using seeds in a simple and reliable manner. After placing reinforcing bars in the grooves, concrete is sprayed to fill the grooves to form a concrete lattice frame that is approximately flush with the slope surface, and then the concrete frame surrounded by the lattice frame is The purpose is to sow plant seeds within the soil.

削する。The details of the embodiment of the present invention will be explained with reference to the drawings. In the slope, groove holes 1 in a grid pattern are excavated at appropriate intervals, usually at intervals of 3 to 5 m.

３を形成する。The width and depth of the slot 1 are usually approximately 0.5 m, and inside the slot 1 there is a reinforcing bar 2 with a diameter of 16 to 251 nm.
After framing and arranging the grooves 1, concrete is sprayed to fill the grooves 1 to form a lattice frame 3 of reinforced concrete.

種子の流室等を確実に阻止することができる。In the construction method of the present invention, as described above, a reinforced concrete lattice frame is poured into a groove excavated on a slope to fill it to form a concrete lattice frame that is approximately flush with the slope. Since plant seeds are sprayed on the slope surrounded by a frame, the reinforced concrete filled in the excavated trench integrates with the slope soil, reinforcing and stabilizing the slope and preventing rainwater from stagnating. Therefore, it is possible to strengthen the slope and green it with plants at the same time and easily.In particular, it is possible to reliably prevent gully erosion caused by rainfall, partial sliding of slope soil, and flow chambers of plant seeds. can be prevented.
