Underground cavity structure in-situ demolition construction method
The invention discloses an in-situ dismantling construction method for an underground cavity structure. The in-situ dismantling construction method comprises the following steps that S1, distribution of advance holes and obstacle clearing holes is determined according to the position of the underground cavity structure to be dismantled; s2, a full-slewing drilling machine is used for driving the casing pipe to break an underground cavity structure from the position of the first hole, and the structure in the casing pipe is cleaned; s3, the interior of the underground cavity structure and the first-opened holes are backfilled and compacted through flow-state solidified soil from the first-opened holes; s4, a full-slewing drilling machine is used for driving a sleeve to break the underground cavity structure according to the selected obstacle clearing hole position, the internal structure of the sleeve is cleared, and after flow-state solidified soil is used for backfilling the generated hole, obstacle clearing of the next obstacle clearing hole is conducted till obstacle clearing of the underground cavity structure is completed; the method has the advantages of being small in vibration and disturbance, convenient to construct and short in construction period.
本发明公开一种地下空腔结构原位拆除施工方法，包括如下步骤：S1、根据待拆的地下空腔结构位置确定的先行孔及清障孔分布；S2、使用全回转钻机驱动套管从先行孔位置破开地下空腔结构，并清理套管内部的结构；S3、从先行孔中用流态固化土将所述地下空腔结构内部及先开孔洞回填密实；S4、使用全回转钻机驱动套管按选定的清障孔位置破开所述地下空腔结构，并清理套管内部的结构，使用流态固化土回填产生的孔洞后，进行下一清障孔的清障，直到地下空腔结构清障完毕；本发明有着振动和扰动小、施工方便、工期短的优点。
