Civil construction foundation pit drainage structure and construction method thereof
The civil construction foundation pit drainage structure comprises a drainage cylinder installed in a foundation pit, the drainage cylinder comprises an installation plate, an outer cylinder body, an inner cylinder body and a separation bottom plate, a filtering cavity is formed between the outer cylinder body and the inner cylinder body, and first filtering holes and second filtering holes are formed in the lower end surfaces of the inner cylinder body and the outer cylinder body correspondingly; a pump column is slidably inserted into the inner barrel, a tunneling drill is rotatably mounted at the bottom end of the drainage barrel, a driving assembly is further arranged on the drainage barrel, and the tunneling drill is controlled to act through the driving assembly. According to the drainage structure, along with layered excavation of the foundation pit and downward pushing of the drainage cylinder layer by layer, the rainfall depth is controlled to be 0.5-1 m below the excavation layer, the gradient of a rainfall funnel line is slowed down, disturbance to underground water of the next excavation layer is reduced, the influence of horizontal radial flow of the underground water is reduced, and the rainfall volume is reduced; it is guaranteed that the excavated layer can be rapidly dewatered and drained, and convenience is provided for execution and monitoring of on-demand dewatering.
本发明公开了种土建施工基坑排水结构，包括安装在基坑内的排水筒，所述排水筒包括安装板、外筒体、内筒体和分隔底板，外筒体和内筒体之间形成一个过滤腔室，内筒体和外筒体的下端表面分别开设有第一滤孔和第二滤孔，内筒体内滑动插设有泵柱，排水筒的底端转动安装有掘进钻，且排水筒上还设置有驱动组件，通过驱动组件控制掘进钻动作。本发明提出的排水结构，随着基坑的分层开挖，排水筒逐层向下推进，将降水深度控制在开挖层以下0.5‑1米，放缓降水漏斗线的坡度，降低对下一层开挖层地下水的扰动，减小地下水水平径向流的影响，缩小降水体量，保证开挖层能够快速降水、疏干，为按需降水的执行和可监控提供便利。
