Construction method of foundation pit supporting waterproof curtain
The invention relates to the field of foundation pit water stopping, in particular to a novel construction method for a foundation pit supporting waterproof curtain, which comprises the following specific steps: firstly, leveling a site; secondly, measuring and setting out to determine the pile positions of a plurality of stirring water stop piles and the pile positions of a plurality of pouring support piles; secondly, a cement mixing pile machine is arranged at one pile position of the multiple mixing water stop piles; then, sinking and lifting of a stirring head of the cement stirring pile machine are repeated twice, and cement paste is sprayed during sinking and lifting of the stirring head so as to construct the stirring water stop piles correspondingly; the multiple stirring water stop piles are distributed in a row shape, and the size of the net pile distance between every two adjacent stirring water stop piles ranges from 400 mm to 800 mm. Finally, after the construction of the first stirring water stop pile is completed for at least 8 hours, pouring support piles are constructed between every two adjacent stirring piles; the size of the meshing width of the pouring support pile and the two adjacent stirring water stop piles ranges from 200 mm to 300 mm. The foundation pit supporting waterproof curtain has the effect that the foundation pit supporting waterproof curtain can be conveniently constructed in a soft soil layer and a sand layer.
本申请涉及基坑止水领域,尤其涉及一种基坑支护止水帷幕的施工新工法，其包括具体以下步骤：首先整平场地；其次测量放样确定若干搅拌止水桩的桩位和若干灌注支护桩的桩位；再其次在若干搅拌止水桩的其中一个桩位设置水泥搅拌桩机；然后使水泥搅拌桩机的搅拌头的下沉和提升均重复两次，并且在搅拌头下沉和提升时均喷射水泥浆以分别施工各搅拌止水桩；若干搅拌止水桩呈排状分布，两相邻搅拌止水桩的净桩间距的尺寸为400mm‑800mm；最后在第一根搅拌止水桩施工完成至少8h后，分别在各相邻的两根搅拌桩之间施作灌注支护桩；灌注支护桩与两相邻搅拌止水桩的咬合宽度的尺寸均为200mm‑300mm。本申请具有便于在软土层和砂层施作基坑支护止水帷幕的效果。
