In order to improve the stability of the foundation pit support of the Guangming Water Treat-ment Complex,the cumulative settlement change value will be controlled within the minimum range,and re-search on the construction technology of foundation pit support will be carried out.The excavation of founda-tion pit earthwork is carried out using the method of layered and segmented earthwork.A support structure consisting of reinforced concrete pouring piles,high-pressure rotary spraying piles,and mixing piles is select-ed,and mud suitable for foundation pit support is prepared.Finally,the installation of the casing will be carried out,and during the construction process,the rotary excavation into a hole for pouring piles will be carried out,and the hole cleaning work will be completed.The practical application proves that the applica-tion of new support construction technology can control the cumulative settlement variation within the range of-5mm～+5mm,fully meeting the support construction requirements of the project,and effectively improving the stability of the foundation pit of the Guangming Water Treatment Complex.
