小型沉箱适合于地下水位较高,地下水较多,施工场地狭窄,地下没有特殊障碍物而又不宜大开挖施工的项目。它具有挖土少,占地少,对邻近建(构)筑物影响小等特点。因此,在地下水位较高,场地较小,或在已建厂房内修建储水池、储油池和设备基础等工程时常被采用。沉箱的施工是边挖土边靠沉箱本身的自重下沉而完成的。沉箱下沉过程中,当遇到土质不均匀,有地下障碍物或出现其它异常情况时,往往会发生因沉降不均匀而倾斜,难以控制设计标高及无法进
Small caisson is suitable for projects with high groundwater level, large amount of groundwater, narrow construction site, no special obstacles underground, and not suitable for large excavation construction. It has features such as less excavation, less land occupation, and small impact on nearby buildings (structures). Therefore, projects such as the construction of reservoirs, reservoirs, and equipment foundations are often used when the groundwater table is high, the site is small, or the existing building is built. The construction of the caisson was completed by digging the earth while relying on the weight of the caisson itself. In the sinking process of the caisson, when the soil is uneven, there are underground obstacles or other abnormal situations occur, it often happens that the slope is uneven due to uneven settlement, it is difficult to control the design elevation and can not enter
