CONSTRUCTION METHOD FOR GROUNDWATER PURIFICATION WALL WITH BUILT-IN OBSERVATION WELL, AND INPUT CAN
PROBLEM TO BE SOLVED: To provide a construction method for a groundwater purification wall with a built-in observation well that does not cause a problem in material separation and enables management of the underground purification wall, even when a groundwater purification material comprises a plurality of materials having different specific gravity values.SOLUTION: A construction method for a groundwater purification wall includes the following steps for: inserting a casing 20 into a ground G and erecting an observation well 30 inside the casing; filling a groundwater purification material M in an input can 10 comprising a can body 1 and a lower cover 2 fitted on the can body, after fitting a first hanging wire 4 to the can body 1 and a second hanging wire 3 to the lower cover, then hooking the wires 3, 4 to separate hanging wire hooks 5, 6 of a heavy machinery, then lowering the input can 10 into the observation well 30 without interference, using only the second hanging wire 3, then hanging the input can 10 with the first hanging wire 4, opening the lower cover 2 and dropping the groundwater purification material M, then lifting the input can 10 with the first hanging wire 4, hanging the input can 10 only with the second hanging wire 3, and filling the groundwater purification material M; and repeating the steps for constructing a groundwater purification wall 100.SELECTED DRAWING: Figure 8
【課題】地下水浄化材が比重の異なる複数の材料の混合材からなる場合でも材料分離の問題が生じ得ず、地下水浄化壁の管理を可能とする観測井戸を内蔵した地下水浄化壁の造成方法を提供すること。【解決手段】地盤Ｇにケーシング２０を挿入して観測井戸３０をその内部に建て込むステップ、缶本体１とこれに装着された下蓋２からなる投入缶１０において、缶本体１に第１の吊ワイヤ４、下蓋に第２の吊ワイヤ３を取り付けて地下水浄化材Ｍを詰め、ワイヤ３，４を重機の有する別途の吊ワイヤフック５，６に掛け、第２の吊ワイヤ３のみで投入缶１０を観測井戸３０に干渉しないようにして吊り下し、第１の吊ワイヤ４に投入缶１０を吊らせて下蓋２を開いて地下水浄化材Ｍを落とし込み、第１の吊ワイヤ４にて投入缶１０を吊り上げ、第２の吊ワイヤ３のみで投入缶１０を吊って地下水浄化材Ｍを詰めるステップ、このステップを繰り返して地下水浄化壁１００を造成するステップからなる。【選択図】図８
