本発明は、例えば急傾斜地の法面の崩壊を抑制するため
に行う傾斜面に対するモルタル吹付工法に関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a mortar spraying method for a sloped surface, which is performed, for example, to suppress the collapse of a slope on a steep slope.
（従来の技術）
急傾斜地の法面の崩壊を抑制するための吹付工法には、
圧縮空気によりコンクリートを吹付けるコンクリート吹

空気を供給することもある）吹付ける湿式１法とがある
。(Conventional technology) The spraying method for suppressing slope collapse on steep slopes includes:
There is a concrete spraying method in which concrete is sprayed using compressed air, and a mortar spraying method in which mortar is sprayed. These painting methods include dry spraying, in which cement and aggregate are mixed together and sent to a nozzle, where they are combined with water and sprayed with compressed air, and dry spraying, in which all materials are kneaded in a mixer and sent to a nozzle. There is a wet method in which air is sprayed (compressed air may be further supplied here if necessary).
一般に法面の吹付けには、コンクリートを用いる場合に
は乾式、モルタルを用いる場合には湿式が主として利用
されている。In general, for slope spraying, the dry method is mainly used when concrete is used, and the wet method is mainly used when mortar is used.
またコンクリート吹付けとモルタル吹付けとの使い分け
は、前者が主として鉄筋コンクリートであり、半永久的
構造物として扱われるのに対して、後者は付着性、一体
性増強のためにラス金網は用いるが、寿命ｌＯ年〜数１
０年程度の構造物として扱われる場合が多い。The distinction between concrete spraying and mortar spraying is that the former is mainly made of reinforced concrete and is treated as a semi-permanent structure, whereas the latter uses lath wire mesh to enhance adhesion and integrity, but has a long lifespan. lO year ~ number 1
In many cases, it is treated as a structure with a lifespan of about 0 years.
本発明はモルタル吹付工法のうち、圧倒的に多用されて
いる湿式吹付工法に関するものである。The present invention relates to the wet spraying method, which is by far the most widely used mortar spraying method.
従来の湿式モルタル吹付けには通常下記のような配合割
合のものを使用している。In conventional wet mortar spraying, the following compounding ratios are usually used:
即ち、上述のような配合のＡモルタルを厚さ１０口前後
で吹付けている。That is, mortar A having the above-mentioned composition is sprayed to a thickness of about 10 holes.
（発明が解決しようとする問題点）
しかしながら上述した従来のモルタル吹付工法にあって
は、前記したように、寿命も短く、特に地下水の浸出が
ある場所では極端に強度が小さく、また凍結・融解サイ
クルの頻繁なところでも寿命が短くなるため、このよう
なところでは短いインターバルでの補修（上吹き・又は
部分剥離させたうえで、上吹き等を行う補修）を必要と
することが多くなるという問題点があった。(Problems to be Solved by the Invention) However, as mentioned above, the conventional mortar spraying method has a short lifespan, has extremely low strength especially in areas where underground water seeps, and is susceptible to freezing and thawing. The lifespan of the product will be shortened even in places where it is cycled frequently, so in such places it is often necessary to repair the product at short intervals (top-spraying, or repairs that include top-spraying after partially peeling off the surface). There was a problem.

より著しく少なくて済むことになる。(Function) As mentioned above, in the present invention, styrene butadiene rubber latex (hereinafter referred to as SBR latex) is mixed into mortar A and is wet-sprayed onto the inclined surface. This significantly improves conventional wet mortar walls, resulting in a longer lifespan, without losing strength in areas with groundwater seepage, and in areas subject to frequent freeze-thaw cycles. Since the service life of the new method is not shortened as much as in the conventional method, the number of repair operations required is significantly less than with the conventional method.

Since we wet-sprayed the mortar mixture onto the slope, the conventional wet mortar walls were significantly modified, which not only extended the life of the sprayed mortar layer, but also prevented groundwater seepage. It has the advantage that the number of repair work is significantly reduced compared to conventional methods, as the strength does not decrease as in conventional methods even in certain places, and the service life does not shorten as in conventional methods even in areas with frequent freezing and thawing cycles. is obtained.
