Tube well dewatering construction method for deep foundation pit adjacent to existing building and containing quicksand layer
The invention discloses a tube well dewatering construction method for a deep foundation pit adjacent to an existing building and containing a quicksand layer. Comprising the following steps; the method comprises the steps of construction preparation, determination of a tube well layout scheme, equipment entering, surveying and setting out, foundation pit support construction and completion of tube well construction. Safety of surrounding buildings is effectively guaranteed, it is guaranteed that a tube well filter tube is not blocked in the dewatering process, the pressure-bearing dewatering well is sealed at a time, and the quicksand phenomenon of a silt stratum is prevented.
本发明公开了一种紧邻既有建筑物含流砂层深基坑管井降水施工方法，其特征在于；包括以下步骤；施工准备、确定管井布设方案、设备进场、测量放线、基坑围护施工、管井施工完成。本发明有效保证周边建筑安全，保证降水过程中管井滤管不淤堵，使承压降水井封井一次完成，防止粉砂地层流砂现象发生。
