Water gushing treatment method for foundation pit with unclosed survey hole
The invention discloses an unclosed investigation hole foundation pit gushing water treatment method which is characterized in that an inverted filter layer is adopted to be matched with a local well point pipe dewatering square, local drainage and drainage of unclosed investigation hole foundation pit gushing water are achieved, and the method specifically comprises the steps of well point pipe burying, inverted filter layer arrangement, well point auxiliary dewatering and the like. Compared with the prior art, the method has the advantages that construction is convenient, dewatering is fast, the treatment effect is good, a well point pipe floral pipe filter head for well point dewatering adopts long and short filter pipes, clay or other sealing means do not need to be adopted at the top end of a well point pipe, the filter head is mainly used for draining open water gathered by an inverted filter layer, dewatering of a soil body within a certain depth range below the inverted filter layer is considered, and the construction period is shortened. The inverted filter layer is mainly used for preventing soil mass loss of the top plate, has the effects of ballasting and catchment, can quickly realize well-point dewatering and solve potential safety hazards, is a powerful auxiliary dewatering method for foundation pit dewatering with potential upper and lower hydraulic connection channels, and has certain popularization and application prospects.
本发明公开了一种未封闭勘察孔基坑涌水处理方法，其特点是采用反滤层配合局部井点管降水的方方，实现未封闭勘察孔基坑涌水的局部疏干和排水，具体包括：井点管的埋设、反滤层的设置和井点辅助降水等步骤。本发明与现有技术相比具有施工方便，降水快，处理效果好，井点降水的井点管花管滤头采用长短滤管设置，且井点管顶端不需要采用粘土或其他密封手段，它主要是疏干反滤层汇聚明水，并兼顾反滤层下一定深度范围内土体的降水，该反滤层主要作用是预防顶板土体流失，并起到压重和汇水的作用，可较快实现井点降水，解决安全隐患，是有潜在上下水力联系通道的基坑降水的强有力辅助降水方法，具有一定的推广应用的前景。
