Airtight earthwork throwing and filling construction process
The invention relates to an airtight earthwork throwing and filling construction process. The airtight earthwork throwing and filling construction process comprises the following steps of (S1) preparing for construction: collecting basic data, and defining a measurement control point and a reference point of a project; (S2) dividing a soil sampling area; (S3) constructing soil retaining plates: constructing a plurality of soil retaining plates near the side, which deviates from the open sea side, of a main levee, and forming gaps between every two adjacent soil retaining plates; (S4) excavating mud flat sludge: excavating in a shallow excavation and wide extraction mode; (S5) performing airtight earthwork throwing and filling construction: firstly, pumping airtight earthwork in throwing and filling areas between the soil retaining plates and the main levee, then throwing and filling the airtight earthwork in throwing and filling areas between the adjacent soil retaining plates, finally, throwing and filling the airtight earthwork in throwing and filling areas between a sub levee and the soil retaining plates, and propelling according to the principle of thin-layer alternate addingand balanced ascending; (S6) detecting and supplementing to throw; and (S7) performing slope arrangement: repairing the slope of the airtight earthwork after the airtight earthwork is solidified. Theconstruction process of the airtight earthwork has the effect of improving the anti-seepage performance of the main levee.
本申请涉及一种闭气土方抛填施工工艺，其包括以下步骤：S1、施工准备：收集基础资料，明确工程的测量控制点和基准点；S2、取土区划分；S3、构筑挡土板：在主堤背离外海侧的一侧附近构筑多块挡土板，令相邻的挡土板之间具有间距；S4、滩涂淤泥开挖：采用浅挖广取的方式开挖；S5、闭气土方抛填施工：将闭气土方首先泵送至挡土板与主堤之间的抛填区域内，再向各相邻的挡土板之间的抛填区域内抛填闭气土方，最后向子堤与挡土板之间的抛填区域内抛填闭气土方，按“薄层轮加、均衡上升”的原则推进；S6、检测补抛；S7、理坡：待闭气土方固结后，对闭气土方的边坡进行修理；本申请闭气土方的施工工艺具有提高主堤防渗水性能的效果。
