Miscellaneous soil hard shell layer drainage plate surcharge preloading settlement construction method
The invention provides a miscellaneous soil hard shell layer drainage plate surcharge preloading settlement construction method. The miscellaneous soil hard shell layer drainage plate surcharge preloading settlement construction method comprises the following steps that a working surface is cleaned and leveled; a first sand cushion layer is paved; a plurality of to-be-guided hole points are marked in a to-be-guided hole area of the working surface, wherein the multiple to-be-guided hole points form a point placement grid; hole guiding treatment is conducted, specifically, a hollow steel chisel is controlled through a hole guiding machine to conduct hole guiding in the to-be-guided hole points to form an inserting hole, a plurality of exhaust holes are formed in the lower portion of the steel chisel, in the hole guiding process, the hole guiding machine controls the steel chisel to move downwards while supplying gas into the steel chisel, the gas is exhausted outwards from the exhaust holes in the steel chisel and released into a soil body, and the gas can damage the stress of the soil body; a drainage plate is inserted and hit: the drainage plate is inserted into the insertion hole; a second sand cushion layer is paved and a settlement observation plate is pre-buried; and surcharge preloading is carried out. According to the miscellaneous soil hard shell layer drainage plate surcharge preloading settlement construction method, the drainage plate is convenient to insert and hit and the stress of a hard shell layer can be eliminated, so that the soil body uniformly settles in the surcharge preloading process in the later period.
本发明提供一种杂土硬壳层排水板堆载预压沉降施工方法，包括如下步骤：清理并整平工作面；摊铺第一层砂垫层；在工作面的待引孔区域标记多个待引孔点，多个待引孔点形成放点网格；引孔处理：通过引孔机控制中空的钢钎在待引孔点中引孔，形成插孔，钢钎的下部设置有多个排气孔，在引孔过程中，引孔机一边控制钢钎下移，一边向钢钎内部供气，气体从钢钎上的排气孔向外排出并释放至土体中，气体能破坏土体的应力；插打排水板：在插孔内插入排水板；摊铺第二层砂垫层并预埋沉降观测板；堆载预压。本发明方便插打排水板并能消除硬壳层应力，使得后期土体在堆载预压过程中均匀沉降。
