Demolition method for column reserved in underground diaphragm wall
The invention provides an underground diaphragm wall reserved column dismantling mode. The underground diaphragm wall reserved column dismantling mode comprises the steps that safety range calculation is conducted on an underground diaphragm wall needing to be dismantled; preparation work before construction is conducted; paying off and positioning a column reserving range and a dismantling part; after the hoisting hole and the rope saw hole are drilled, a rope saw is used for cutting the underground diaphragm wall; after the crane safely stands, the cut underground diaphragm wall is hoisted and transported outwards; stripping concrete at the joint of the column and the plate, welding a water stop steel plate, and constructing a post-cast strip; the post-cast strip concrete is cured; and the indwelled column is dismantled. According to the method, the underground diaphragm wall in the middle of the connector is disassembled firstly, so that the underground diaphragm walls at the two ends of the connector are disassembled after the bearing structure system is converted without instability, vibration and disturbance to the structure system are small, noise is low, dust is little, and cost is low.
本申请提供一种地连墙留柱拆除方式，包括对需要拆除的地连墙进行安全范围计算；进行施工前的准备工作；放线定位留柱范围和拆除部位；钻吊装孔与绳锯孔后，用绳锯对地连墙进行切割；吊车安全站位后对切割后的地连墙进行吊装外运；剥离柱子与板块连接处的混凝土，焊接止水钢板，施工后浇带；对后浇带混凝土进行养护；拆除留置的柱子。该方法通过先拆接口中间部分的地连墙，使得承载结构体系转换不失稳后再拆接口两端的地连墙，对结构体系振动、扰动小，且噪音小、灰尘少、成本低。
