Research on the Construction Technology of Foundation Pit Support for Water Purification Treatment Complex of Guangming Water Plant
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.
