Description
本考案は、地盤改良時の土壌掘削と固化材との混合攪拌に用いる装置に関するものである。 The present invention relates to an apparatus used for mixing and agitation of soil excavation and solidifying material during ground improvement.
地盤改良の目的で、土壌と生石灰やセメント系固化材を混合攪拌し、地盤改良する方法が従来から知られている。 For the purpose of ground improvement, a method of improving the ground by mixing and stirring soil, quicklime and cement-based solidified material has been known.
従来、地盤改良装置の攪拌翼は「らせん状」のものが多く使われていた。 Conventionally, the stirring blades of the ground improvement device have been used in many “spiral” shapes.
従来の装置はロータリー部が「らせん状」で、攪拌土が一方向に動くため均一な混合は難しいとされ、同時に本体が横に振られることから、破損が多いという問題点があった。 The conventional apparatus has a problem that the rotary part is “spiral” and the stirring soil moves in one direction, so that uniform mixing is difficult, and at the same time, the main body is shaken sideways, which causes many breaks.
本考案は、従来の問題点を解決するもので、土壌と固化材との均一な混合攪拌を可能とした地盤改良装置を提供するものである。 The present invention solves the conventional problems and provides a ground improvement device that enables uniform mixing and stirring of soil and solidified material.
上記目的を達成するため、この考案の装置のひとつは、土壌と固化材との混合において、偏らず均一に攪拌できる羽根の型を特徴とした。
また、攪拌翼の取り付け角度を１５度としてセンターに向けて装着し、土壌と固化材との混合効率の良い均一な改良が出来る装置とした特徴がある。
この考案の装置は、攪拌時の横揺れ等を防止するため、装置下部両サイドにズレ止め爪を装着したことを特徴とする。In order to achieve the above object, one of the devices of the present invention is characterized by a blade shape that can be uniformly stirred evenly in the mixing of soil and solidified material.
Moreover, the mounting angle of the stirring blade is set to 15 degrees and is mounted toward the center, and there is a feature that the apparatus can perform uniform improvement with good mixing efficiency between the soil and the solidified material.
The device of the present invention is characterized in that slippage preventing claws are mounted on both sides of the lower part of the device in order to prevent rolling or the like during stirring.
従来の装置は、攪拌翼の型が「らせん状」のものが多く、そのことから攪拌土が一方向に動くため、固化材との均一な混合が容易でなく、加えて力が横方向に働く関係で本体が振られ、改良作業に支障をきたす状況にあった。
これらの問題解決のため考案した装置は、攪拌翼を装置の中心部より概ね左右対称とし、羽根の角度も１５度方向として固化材との均一な改良を容易にし、本体が横に振れることもなく均質で攪拌効率の良い地盤改良を可能とした。Many of the conventional devices have a “spiral” type of agitating blades, which means that the agitating soil moves in one direction, so uniform mixing with the solidified material is not easy, and in addition, the force is in the lateral direction. The main body was shaken due to working relations, and the improvement work was hindered.
In the device devised to solve these problems, the agitating blade is generally symmetrical from the center of the device, the blade angle is also 15 degrees, facilitating uniform improvement with the solidified material, and the main body can swing sideways. It was possible to improve the ground with a homogeneous and efficient stirring.
図１の地盤改良装置は、バックホーを母機として、そのアームの先端に装着するものであり、土壌の掘削と固化材との攪拌混合の為の油圧モーターによるチェーン駆動式装置である。 The ground improvement device of FIG. 1 is a chain drive type device using a hydraulic motor for excavating soil and stirring and mixing with a solidified material, with a backhoe as a mother machine and attached to the tip of the arm.
図１，２に示すように、土壌と固化材との攪拌混合効率を高めるため、攪拌翼の取り付け位置を中心部より概ね左右対称とし、軸に対し縦横ともに２枚以上の羽根が並ばないよう設定している。 As shown in Figs. 1 and 2, in order to increase the stirring and mixing efficiency of the soil and the solidified material, the mounting position of the stirring blades is generally left-right symmetric from the center so that two or more blades do not line up vertically or horizontally with respect to the axis. It is set.
図２に示すように、攪拌翼の取り付け角度を１５度としてセンターに向けて装着し、均一で効率の良い改良が出来るよう設定している。 As shown in FIG. 2, the mounting angle of the stirring blade is set to 15 degrees and is mounted toward the center so that uniform and efficient improvement can be achieved.
図１，３に示すサイドカッターは、攪拌翼回転時の衝撃（横揺れ）を防止するために装着したものである。 The side cutter shown in FIGS. 1 and 3 is mounted in order to prevent an impact (rolling) during rotation of the stirring blade.
