Silty clay foundation dewatering device and method
The invention discloses a silty clay foundation dewatering method which comprises the steps that before foundation construction, at least one filter cover is pre-buried in a foundation pit, the filter cover comprises a filter pipe, a first filter screen and a second filter screen, a plurality of filter holes are formed in the filter pipe, and the filter holes are communicated with the first filter screen and the second filter screen; the first filter screen and the second filter screen are sequentially coated outside a plurality of filter holes of the filter pipe; the first filter screen is a nylon wire screen of 8-16 meshes, and the second filter screen is made of a nylon or plastic window screen; hoisting a submersible pump into the filter pipe; and the submersible pump is started to pump out water filtered by the filter cover in the foundation pit. In addition, the invention further provides a silty clay foundation dewatering device. According to the method, the precipitation effect of the silty clay foundation can be remarkably improved, and high practicability is achieved.
本发明公开了一种粉质粘土地基降水方法，包括：在地基基础施工前，在基坑内预埋至少一过滤罩，所述过滤罩包括一过滤管、一第一滤网和一第二滤网，所述过滤管上开设有多个滤孔，所述第一滤网和所述第二滤网依次包覆于所述过滤管的多个滤孔外；所述第一滤网采用8‑16目的尼龙丝筛网，所述第二滤网采用尼龙或塑料窗纱制成；将潜水泵吊装至所述过滤管内；以及启动所述潜水泵以将基坑内经过滤罩过滤后的水抽出。此外，本发明还提供一种粉质粘土地基降水装置。本发明可以显著提高粉质粘土地基的降水效果，具有较高的实用性。
