Construction process for deep foundation pit enclosure curtain
The invention discloses a deep foundation pit enclosure curtain construction technology and belongs to the technical field of enclosure curtain construction. The deep foundation pit enclosure curtain construction technology comprises the specific steps that S1, cast-in-situ bored pile construction is conducted; and S2, TRD cement soil stirring wall forming construction is adopted between the cast-in-place piles. According to the construction method, by optimizing the construction method of the cast-in-situ bored piles and adopting TRD cement soil stirring wall forming construction, the strength of the enclosure curtain is effectively improved, the more reliable supporting effect is provided, and therefore potential risks in the foundation pit construction process are reduced; compared with a traditional method, the TRD cement soil stirring wall forming construction method has the advantage that the influence of vibration and noise on the enclosure curtain is reduced. The method is particularly critical to the construction around the subway, and is beneficial to reducing adverse effects on subway facilities and nearby buildings.
本发明公开了一种深基坑围护帷幕施工工艺属于围护帷幕施工技术领域，包括具体步骤包括：S1：钻孔灌注桩施工；S2：在灌注桩之间采用TRD水泥土搅拌墙成墙施工。本发明通过优化钻孔灌注桩的施工方法和采用TRD水泥土搅拌墙成墙施工，有效提高了围护帷幕的强度，提供更可靠的支护效果，从而减少基坑施工过程中的潜在风险；采用TRD水泥土搅拌墙成墙施工方法相较于传统方法，减少了振动和噪音对围护帷幕的影响。这对于地铁周围的施工尤为关键，有助于减小对地铁设施和附近建筑物的不良影响。
