Vertical support curtain construction method for space-limited deep foundation pit
The invention relates to the technical field of civil construction, and discloses a vertical support curtain construction method for a space-limited deep foundation pit, which comprises the following steps: S1, measuring and drilling: measuring and determining the pile hole position of a steel floral tube, and drilling by using a drilling machine; s2, a steel floral tube is manufactured, wherein the tube diameter of the steel floral tube is 100-300 mm, and a plurality of grout overflow holes are evenly formed in a tube body of the steel floral tube; s3, mounting the steel floral tube: hoisting and mounting the steel floral tube into the pile hole; s4, grouting is conducted, specifically, grouting is conducted in the steel floral tube; s5, a top beam foundation trench is excavated, specifically, after grouting of all the steel floral tubes is completed, maintenance is conducted for 5-7 days, and the top beam foundation trench at the top is excavated; s6, top beam pouring is conducted, specifically, concrete is poured into a top beam foundation trench, and after pouring is completed, maintenance is conducted for 5-7 days; s7, support acceptance; and after acceptance check, an informatization method is adopted in the foundation pit excavation process to continuously monitor the support, and the deformation of the foundation pit is smaller than or equal to 2 cm. In practical application, the purpose that deep foundation pit supporting operation can be conducted in a built building or a limited space where a large machine tool cannot enter is achieved.
本发明涉及土建施工技术领域，公开了一种空间受限深基坑的垂直支护帷幕施工方法，包括以下步骤：S1、测量钻孔：测量确定钢花管的桩孔位置，并利用钻机进行钻孔；S2、钢花管制作：钢花管的管径为100～300mm，且钢花管的管身上均匀设有多个溢浆孔；S3、钢花管安装：将钢花管吊装安装到桩孔中；S4、注浆：往钢花管内注浆；S5、挖冠梁基槽：所有钢花管注浆完成后，养护5～7天，开挖顶部的冠梁基槽；S6、浇筑冠梁：将混凝土浇筑在冠梁基槽中，浇筑完成后，养护5～7天；S7、支护验收；验收后，基坑开挖过程中采用信息化法对支护持续监测，基坑变形量≤2cm。实际应用时，本发明实现了在已建建筑物内或大型机具无法进入的受限空间场所内可进行深基坑支护操作的目的。
