Foundation pit sudden gushing prevention device
The invention discloses a foundation pit outburst prevention device, and relates to the technical field of construction safety, the foundation pit outburst prevention device comprises a pressure relief well and a plurality of drainage pipelines which are buried in a soil layer at the bottom of a foundation pit, and a drainage well arranged on the bottom wall of the foundation pit, the bottom of the pressure relief well is opened, and a water seepage layer is arranged in the pressure relief well; the drainage pipelines are communicated with the pressure relief well, a plurality of water through holes are formed in the side walls of the drainage pipelines, an overflow opening is formed in the side wall of the pressure relief well, the overflow opening is communicated with an overflow pipe, the overflow pipe is communicated with the drainage well, and a water suction pump used for pumping away accumulated water in the drainage well is arranged above the drainage well. The underground water at the bottom of the foundation pit is not prone to gushing, and therefore the construction safety is effectively guaranteed.
本申请公开了一种基坑防突涌装置，涉及施工安全的技术领域，其包括埋设在基坑底部土层内的泄压井和若干泄水管道，以及设置在基坑底壁的疏干井，所述泄压井的底部开口设置，所述泄压井内设置有渗水层，各所述泄水管道均与泄压井连通，所述泄水管道的侧壁开设有若干通水孔，所述泄压井的侧壁开设有溢流口，所述溢流口连通有溢流管，所述溢流管与疏干井连通，所述疏干井的上方设置有用于将疏干井内积水抽离的抽水泵。本申请具有基坑底部的地下水不易发生突涌，从而有效保证施工安全性的效果。
