【発明の属する技術分野】本発明は、主として推進工法
にて掘削する地中掘削等に用いられる滑材に関するもの
である。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliding material mainly used for underground excavation excavated by a propulsion method.
【０００２】[0002]
【従来の技術】推進工法では、推進管周辺に滑材を噴出

Description of the Related Art In a propulsion method, a lubricating material is spouted around a propulsion pipe and used to reduce a frictional load generated between the lubrication material and the ground. As the lubricating material used at the site of underground excavation by this propulsion method, bentonite dried on clay is used, and mud oil, high gel, thickener is added to it and dispersed and swelled in water .

【発明が解決しようとする課題】従来のこの種の滑材

時間が長くかかっていた。また、このベントナイトを用
いた滑材は、減摩効果は優れているが、混和剤の種類が
多く必要であり、その調合操作が煩雑なため、誤配合が
発生して、滑材としての一定の性能を発揮できない場合
が生じていた。Since such a conventional sliding material uses dried bentonite, it takes a long time for it to completely dissolve when it is dispersed in water. It was hanging. In addition, although the sliding material using this bentonite has an excellent anti-friction effect, it requires a large number of admixtures, and the compounding operation is complicated, so that erroneous blending occurs, and the sliding material has a certain effect. In some cases, the performance cannot be exhibited.
【０００４】また、この従来の滑材は、透水性の大きい
地層での地下水による希釈拡散が早いため、短時間で逸

る物質であり、このベントナイトを含む滑材を使用した
場合には、環境汚染の問題が生じる。さらに、高吸水性
樹脂だけの滑材は、比重が低いので、地下水圧によって
逸散されてしまうので使用できない場合もあった。[0004] In addition, since the conventional sliding material is rapidly diluted and diffused by groundwater in a highly permeable formation, it is dissipated in a short time and lacks the sustainability of the effect as a sliding material. In addition, bentonite is a substance designated as industrial waste, and if a sliding material containing this bentonite is used, there is a problem of environmental pollution. Further, a lubricating material consisting only of a superabsorbent resin may not be used because it has a low specific gravity and is dissipated by groundwater pressure.

材を提供することを目的とするものである。In view of the above, the present invention has been made in consideration of the above.
It is another object of the present invention to provide a lubricating material for a propulsion method that is free from erroneous compounding and that can be prevented from escaping to the ground.

液でも粘土のダマができない。The above-mentioned sliding material for a propulsion method according to the present invention comprises:
The quarry sludge (sludge) dewatered cake is made of a wet material that is kept wet or a dry material that is used as clay. Compared to dried bentonite, the dissolution rate in water is high. Therefore, it is not possible to lump the clay even with a short liquid preparation.
【００１３】また上記粘土には微量に凝集剤が含有され

り、これにより、増粘剤量が少なくても滑材としての性
能を得ることができる。[0013] Further, since the above-mentioned clay contains a trace amount of a flocculant, the viscosity of the clay is improved as a cross-linking effect, whereby the performance as a lubricant can be obtained even if the amount of the thickener is small. .

め効果が向上され、濾水量が低減される。[0014] In addition, the use of fine dust-removed fine powder generated in the quarry and the sand, gravel, and cobblestone collecting pits as the clay makes it possible to remove the fine powder collected by the dust collector.
Since the ultrafine particles are present as compared with the bentonite that has been subjected to the drying treatment, when it is mixed with the water-absorbing resin, the effect of clogging the ground is improved, and the amount of drainage is reduced.

される。On the other hand, by blending a water-absorbing resin having a higher water-absorbing capacity, a larger water-absorbing capacity is imparted than the conventionally used sliding material, whereby the water-stopping property is enhanced, and it can be applied to a wide range of strata. In addition, the ground clamping force is reduced.
