钢筋混凝土沉井在泵站水利工程中的应用

Application of Reinforced Concrete Sinking Well in Pump Station Hydraulic Engineering

中央财政小型农田水利重点县江川县2016年项目泵站工程中进水池钢筋混凝土沉井施工,位于大街街道办事处石岩哨、螺蛳铺、兰田3个村委会,泵站工程位于星云湖畔(进水池临水建设),该区域的地质主要为第四系(Ql)内陆湖相沉积层,为砂、黏土、介壳层上,厚约0.9~41 m。结合该工程中进水池为钢筋混凝土沉井的施工过程,阐述了钢筋混凝土沉井在泵站水利工程中的应用,对沉井在内陆湖相沉积层,砂、黏土中施工工艺作简述,使之在河岸、湖泊、水下基础、水库输水涵竖井等得到更广泛的推广应用。

In 2016 Pump Station Project in Jiangchuan County,the construction of reinforced concrete caisson for the inlet water tank was carried out in three village committees,namely Shiyanshao,Luoshipu,and Lantian,located in the street office.The pump station project is located on the shore of Xingyun Lake(near the water inlet construction).The geology of this area is mainly composed of Quaternary(Ql)inland lacustrine sedimentary layers,which are sand,clay,and shell layers,with a thickness of about 0.9-41 m.This paper elaborates on the application of reinforced concrete caisson in pump station hydraulic engineering,based on the construction process of reinforced concrete caisson in the water inlet pool of the project.The construction technology of caisson in inland lake sedimentation layer,sand,and clay is briefly described,so that it can be widely promoted and applied in riverbanks,lakes,underwater foundations,and vertical shafts of reservoir water culverts.
