Description
【発明の詳細な説明】 本発明は、シールド推進工法用減摩剤組成物に関する。[Detailed description of the invention] The present invention relates to a lubricant composition for shield propulsion construction method.
詳言すれば、水１００重量部に対して。To be more specific, it is based on 100 parts by weight of water.

減摩剤組成物を提供するものである。Water-in-oil polymer emulsion, or pre-extreme pressure additives,
Water-in-oil polymer emulsion containing lubricants, mineral, animal, and vegetable oils, and emulsifiers (0.2-10%
~20 parts by weight).
シールド推進コニ法は、コンクリートや鋳鉄製管体を油
圧ジヤツキで地中に押し込み、電力線、電信電話線、上
下水道等の地下隨道を構築する工法であり、地表開削を
伴わないので、交通や商業活動への影響が比較的少ない
ことから多用されている。The shield propulsion method is a construction method for constructing underground tunnels for power lines, telegraph and telephone lines, water and sewage lines, etc. by pushing concrete or cast iron pipes into the ground using hydraulic jacks, and since it does not involve excavation of the ground surface, it reduces traffic and It is widely used because it has relatively little impact on commercial activities.
この工法においては、地中に管体を押し込む工法である
ため、推進した管体本数（距離）に応じて押し込みに要
する推進力は増大するので、管体や推進ジヤツキを取り
付けた反力壁の強度の面から推進距離は限定されるとい
う問題がある。In this construction method, the pipes are pushed into the ground, so the driving force required for pushing increases depending on the number (distance) of the pipes pushed, so the reaction wall with the pipes and propulsion jacks There is a problem in that the propulsion distance is limited due to strength.
推進されるべき距離は、長いほど施工上の能率は良好な
ので、距離延長を目的に推進距離に応じて、推進管の間
に数個の中間ジヤツキを設置して推進力を増加させる方
法も採用されている。The longer the distance to be propelled, the better the construction efficiency, so in order to extend the distance, we have also adopted a method of increasing the propulsive force by installing several intermediate jacks between the propulsion tubes depending on the distance of propulsion. has been done.
しかし、中間ジヤツキの設置は推進操作が煩雑となり、
作業効率を著しく低下させるので、多数の中間ジヤツキ
設置は好ましくない。However, installing an intermediate jack makes the propulsion operation complicated,
It is undesirable to install a large number of intermediate jacks because it significantly reduces work efficiency.
他の方法として減摩剤の注入があり、減摩剤として、水
にベントナイト、ＣＭＣ（カルボキシメチルセルローズ
）、ポリアクリル酸ソーダ。Another method is to inject a lubricant, such as bentonite, CMC (carboxymethyl cellulose), or sodium polyacrylate in water.
界面活性剤、鉱物油等を分散させた高粘稠液体を推進管
と他山との間隙に注入してすベリ抵抗を減少させる方法
が特公昭４ｆｌ−１９０６号公報に提案されている。Japanese Patent Publication No. 4FL-1906 proposes a method for reducing slippage resistance by injecting a highly viscous liquid in which a surfactant, mineral oil, etc. are dispersed into the gap between the propulsion tube and another mountain.
この方法は、推進力の減少に比較的高い効果を期待でき

、完全溶解には長時間を要し、不充分な溶解状態では減
摩効果が大幅に低下する等の欠点があり、調合が容易で
短時間で調製でき、満足すべき減摩効果を有する減摩剤
組成物の開発が待たれていた。Although this method can be expected to be relatively effective in reducing the propulsion force, it is complicated to prepare the lubricant because several types of materials are mixed. In addition, since the lubricant has a high viscosity, a dissolving machine dedicated to preparing the lubricant is required, and since glues such as CMC and sodium polyacrylate are powdered, they are completely dissolved. It takes a long time to prepare the lubricant, and if the dissolution state is insufficient, the anti-friction effect is significantly reduced. The development of something was awaited.

たものである。As a result of intensive research regarding these anti-friction agent compositions, the present inventors have found that, with respect to 100 parts by weight of water, a wood-in-oil polymer emulsion, or an extreme pressure additive, a lubricant, mineral fauna and flora, etc.
Wood-in-oil polymer emulsion containing an emulsifier (0,2
We have now provided a lubricant composition for shield propulsion construction, which is comprised of ~10 parts by weight of minerals (2 to 20 parts by weight).

てきた減摩剤の欠点を完全に解消したものである。The anti-friction agent in the present invention is used as an aqueous dispersion or in combination with a mineral substance, but it is extremely easy to prepare, and when the anti-friction agent is added to water, it is easily dispersed in water due to the action of an emulsifier. A highly viscous liquid can be obtained in a short period of time, and a lubricant having an excellent antifriction effect can be obtained, completely eliminating the drawbacks of conventionally used lubricants.

It can be adjusted by adding mineral oil, animal or vegetable oil, or an emulsifier to increase water dispersibility.
