SAMPLER FOR SOIL IMPROVEMENT BODY AND SAMPLING METHOD
To provide a sampler for a soil improvement body and a sampling method which take advantage of a procedure of a backfilling construction of a construction hole, facilitate installation and extraction, and can collect a sample in a desired state.SOLUTION: A sampler includes: an inner pipe 1; and an outer pipe 2 having an external diameter larger than an external diameter of the inner pipe 1 and forming a double pipe along with the inner pipe 1. A lowermost part of a gap V between the inner pipe 1 and the outer pipe 2 in an axial direction is closed. The inner pipe 1 separably couples a first inner pipe 11 with a second inner pipe 12 in order from a lower side so as to penetrate in the axial direction.SELECTED DRAWING: Figure 1
【課題】施工孔の埋め戻し工事の手順を活かし、設置及び抜き取りが容易で、かつ所望の状態の試料を採取できる地盤改良体のサンプラー及びサンプリング方法を提供すること。【解決手段】内管１と、内管１の外径より大きい内径で、内管１と共に二重管を形成する外管２と、を備え、軸方向における内管１と外管２との空隙Ｖの最下部は閉鎖され、内管１は、軸方向に貫通して下側から順に第１内管１１と第２内管１２とを分離可能に連結してある。【選択図】図１
