IMPROVEMENT EVALUATION TEST OF GROUND AND METHOD
To increase reliability of improvement evaluation by creating a permeation form as close as possible during actual construction, in an improvement evaluation test of the ground with injection material.SOLUTION: An injection pipe 20 is disposed in a test container 10, an outer periphery thereof is surrounded by a cylindrical diffusion space defining member 22, and a diffusion space 25 is formed between the outer peripheral surface of the injection pipe 20 and the diffusion space defining member 22. In the diffusion space defining member 22, a large number of through holes 22c which allow a permeation of an injection material 3 and limit a passage of a simulated ground 30 are dispersedly formed. The injection material 3 is discharged from an injection hole 20c of the injection pipe 20, spreads into the diffusion space 25, then passes through the diffusion space defining member 22, and penetrates into the simulated ground 30.SELECTED DRAWING: Figure 1
【課題】注入材による地山の改良評価試験において、実際の施工時になるべく近い浸透形態を作り出すことで、改良評価の信頼度を高める。【解決手段】試験容器１０内に注入管２０を配置し、その外周を筒状の拡散空間画成部材２２で囲み、注入管２０の外周面と拡散空間画成部材２２との間に拡散空間２５を形成する。拡散空間画成部材２２には、注入材３の透過を許容し模擬地山３０の通過を制限する多数の透孔２２ｃが分散して形成されている。注入材３は、注入管２０の注入穴２０ｃから吐出され、拡散空間２５内に広がった後、拡散空間画成部材２２を透過して、模擬地山３０に浸み込む。【選択図】図１
