Dismantling method for bottom plate in foundation pit supporting structure
The invention discloses a dismantling method for a bottom plate in a foundation pit supporting structure. The bottom plate comprises a concrete layer and a steel bar layer which are alternately arranged from top to bottom, and the method comprises the following steps that the bottom plate is cut into a plurality of to-be-dismantled areas by utilizing drilling equipment, for each to-be-dismantled area in the plurality of to-be-dismantled areas, crushing equipment and cutting equipment are utilized to alternately conduct dismantling operation layer by layer so as to dismantle the corresponding layer, wherein the crushing equipment is used for crushing the concrete layer, and the cutting equipment is used for cutting the steel bar layer. According to the method, firstly, the bottom plate is divided into a plurality of isolated areas, the bottom plate is dismantled layer by layer in a mode that a breaking pickaxe is used for breaking concrete and a cutting machine is used for cutting off reinforcing steel bars in a matched mode, and therefore simultaneous operation on the plurality of areas on the bottom plate can be achieved, and the dismantling progress is accelerated; and meanwhile, the bottom plate is divided into the plurality of isolated areas, so that the concrete crushing difficulty of the crushing pickaxe is reduced, the steel bar layers are cut layer by layer in cooperation with the cutting machine, and the dismantling efficiency is further improved.
本发明公开了一种基坑支护结构中底板的拆除方法，所述底板从上至下包括交替设置的混凝土层和钢筋层，所述方法包括如下步骤：利用钻孔设备将底板切割为多块待拆除区域；对所述多块待拆除区域中的每块待拆除区域，利用破碎设备和切割设备逐层交替拆除作业以拆除对应层；其中，破碎设备用于破碎混凝土层，切割设备用于切割钢筋层。本发明先将底板分割为多个孤立的区域，并使用破碎镐敲碎混凝土、切割机割断钢筋相配合的方式，逐层拆除底板，能够实现在底板上的多个区域同时作业，加快拆除进度；同时由于将底板分割为多个孤立的区域，降低了破碎镐破碎混凝土的难度，再配合切割机逐层切割钢筋层，进一步提高了拆除效率。
