Method for carrying out pile pulling construction in collapsible loess area
The invention discloses a method for carrying out pile pulling construction in a collapsible loess area. The method includes the steps of S1, sampling: delimiting a specified area by using a soil sampler, and cutting a soil sample in the collapsible loess area to be treated; S2, soil sample testing: placing the cut soil sample in a specified container, then adding water for soaking, and knowing the water soaking amount and the settlement condition of soil; S3, field sampling test: conducting sampling, adding water and soaking in a pretreated area, knowing the water soaking amount of a central area and the settlement condition of the soil, and judging the error rate of a test; S4, punching and water adding: performing punching around an area where pile pulling is needed, setting the punching number according to the actual requirement, and adding water for soaking; and S5, selecting: conducting selecting according to the water immersion amount of the soil test and the field sampling test and the settlement condition of the soil. According to the method for carrying out pile pulling construction in the collapsible loess area, the accuracy of selecting a pile pulling machine can be guaranteed, and the burden of the pile pulling machine can be reduced.
本发明公开了一种在湿陷性黄土地区进行拔桩施工的方法，包括以下步骤：S1、取样：利用取土器，划定指定区域，在待处理湿陷性黄土地上进行切取土样；S2、土样测试：将切取土样置于指定的容器，然后进行加水浸水，了解浸水量以及土壤的沉降情况；S3、实地抽样测试：在预处理的区域进行抽样加水浸水，了解中央区域浸水量以及土壤的沉降情况，判断测试的误差率；S4、打孔加水：然后在需要拔桩的区域周围进行打孔，打孔数量按照实际需要进行排布，并加水浸水；S5、选用：根据土壤测试和实地抽样测试的浸水量以及土壤的沉降情况。该在湿陷性黄土地区进行拔桩施工的方法，不仅能保证选择拔桩机的准确性，还能降低拔桩机的负担。
