STRUCTURE CRUSH SYSTEM
PROBLEM TO BE SOLVED: To provide a structure crush system which crushes part of a concrete structure in a short work period without creating damage on the remaining part.SOLUTION: A structure crush system 1 in this invention comprises: a first circuit 11, which is connected to an output terminal 7a, from which electric energy for ignition is output earliest, and includes a nonexplosive ignition pieces 10 that are arranged on the border 8 of a crushing region 3 and a remaining region 4; a third circuit 14, which is connected to an output terminal 7c, from which electric energy for ignition is output latest, and includes detonators 13 that are arranged in the crushing region 3; a breakage detection circuit 17, which is arranged on the peripheral surface of the pile 2, and includes a breakage detection lead wire 16 that is arranged along the boarder 8, crossing the boarder and being positioned between side-by-side nonexplosive crush agent 9, 9; and a switcher 18, which switches the energization state of a second circuit 15 which is connected to an output terminal 7b, from which electric energy for ignition is output second, to be opposite the energization state of the breakage detection circuit 17.SELECTED DRAWING: Figure 1
【課題】短工期でかつ残置部分に損傷を発生させずにコンクリート構造物の一部を破砕する。【解決手段】本発明に係る構造物の破砕システム１は、点火用電気エネルギーが最も早く送出される出力端子７ａに接続され、破砕予定領域３と残置予定領域４との境界８に配置された非火薬点火具１０が含まれた第１の回路１１と、点火用電気エネルギーが最も遅く送出される出力端子７ｃに接続され、破砕予定領域３に配置された雷管１３が含まれた第３の回路１４と、杭２の周面に配置され、境界８に沿って該境界を跨ぐように、かつ隣り合う非火薬破砕剤９，９の間に位置するように配置された破断検出用導線１６が含まれた破断検出回路１７と、点火用電気エネルギーが二番目に早く送出される出力端子７ｂに接続された第２の回路１５の通電状況を、破断検出回路１７の通電状況と逆になるように切り替える切替器１８とを備える。【選択図】 図１
