Abstract

<P>PROBLEM TO BE SOLVED: To solve problems that the cost is increased or it is difficult to keep the specific gravity constant, since it can't help to depend on a process using lightweight material as aggregate or a process mixing air, when a lightweight grout material is prepared. <P>SOLUTION: The problem is solved by using light weight wood chips as the aggregate. Because it is difficult for the wood chips to be uniformly mixed in a liquid due to its largeness and buoyancy, the wood chips are dispersed by utilizing the swelling property of bentonite to obtain the grout material. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

本発明は、軽量であることを特長とした注入材の配合の一つである。The present invention is one of the formulations of the injection material characterized by being lightweight.

構造物の背面或いは構造上の空間に充填される注入材で、構造物自身の重量を増やす事が少なく、注入材の体積が大きく変化することの無いことを特長とした注入材を必要とされる。There is a need for an injection material that fills the back of the structure or the space on the structure, which does not increase the weight of the structure itself, and does not significantly change the volume of the injection material. The

注入材を軽くする為には、軽量な骨材を用いるか或いは注入材に空気を取り込むことでこれを満たしていた。In order to make the injection material lighter, this was satisfied by using a lightweight aggregate or by taking air into the injection material.

見かけの比重が０．２５である木片を骨材に出来れば軽量な注入材を得られることは容易に考えられるが、その浮力の為注入材全体に均等に混合することが困難であった。If it is possible to use a piece of wood having an apparent specific gravity of 0.25 as an aggregate, it is easy to obtain a lightweight injection material, but due to its buoyancy, it has been difficult to evenly mix the entire injection material.

この均等混合を以下の配合を参考に考案したものである。
特開２００４−１９０２７３号公報 特開平９−２６８０４３号公報 This equal mixing was devised with reference to the following formulation.
JP 2004-190273 A Japanese Patent Laid-Open No. 9-268043

木片を骨材に使い、これを以下の配合で混ぜ合わせることにより軽量で均質なる特長を有する注入材としたものである。A piece of wood is used as an aggregate, and this is mixed with the following composition to make an injection material that is light and homogeneous.

セメント及びベントナイトのｍ３当たり配合を別添の様に行い均一に混合でき所定の強度を得られるようにした。Cement and bentonite were mixed per m3 as shown in the attachment, so that they could be mixed uniformly to obtain a predetermined strength.

木片は必ずしも新材の必要も無いので、廃材間伐材を使用し木材の有効利用を図れるようにした。Since wood pieces do not necessarily require new wood, we have made thin wood from waste wood available for effective use.

本発明は、軽量で水に浮いてしまう木片をベントナイトの膨潤により得られた粘性により配合内全体に拡散し固結するまで位置関係を保つことを特徴とした。The present invention is characterized in that the positional relationship is maintained until a wooden piece that is lightweight and floats on water is diffused and consolidated into the entire blend due to the viscosity obtained by swelling of bentonite.

本発明は、従来比重が違うため水中で均等に混合することの出来なかった木片をベントナイト溶液で包み込み均等に固結するまで分散させることができるような特徴を有するようにした。The present invention has such a feature that a piece of wood that cannot be uniformly mixed in water due to a difference in specific gravity can be wrapped in a bentonite solution and dispersed until uniformly consolidated.

計量した水にまず最初にベントナイトを入れよく撹拌しベントナイトを完全に膨潤させる。
この溶液にセメントを混入しその後更に木片ダストを加え撹拌する。First, add bentonite to the measured water and stir well to swell the bentonite completely.
Cement is mixed into this solution, and then wood dust is further added and stirred.

セメント ２００ｋｇ
ベントナイト ５０ｋｇ
木片ダスト １７０ｋｇ
水 ６１０ｋｇ
