Dewatering structure for preventing underground structure from floating upwards and construction method thereof
The invention discloses a dewatering structure for preventing an underground structure from floating upwards and a construction method thereof. The dewatering structure comprises a water drain pipe, a water stop plate and a gravel filter layer; the drain pipe is arranged at the bottom of a water-collecting well, and the lower end of the drain pipe extends into a soil body below a cushion layer; water drain hole channels are formed in the side wall of the water drain pipe and located in the soil body at intervals; a pipeline of the water drain pipe is filled with an expansive concrete core, and the top face of the expansive concrete core is lower than the top end of the water drain pipe; a plugging plate is arranged in the pipeline of the water drain pipe and located on the top face of the expansive concrete core; the water drain pipe above the plugging plate is filled with a sealant; the water stop plate is annular and is welded to the outer side wall of the water drain pipe; the periphery of the water drain pipe is filled with the gravel filtering layer, and the top face of the gravel filtering layer is flush with the bottom face of the cushion layer; and the outer side of the gravel filtering layer is wrapped with geotechnical cloth. The technical problems that a traditional bottom plate reserved dewatering pipe well is complex in construction procedure, leakage is prone to occurring in the later period, and the dewatering well is damaged or stops running in the construction period of a basement main body structure are solved.
一种防止地下结构上浮的降水结构及其施工方法；包括泄水管、止水板和碎石过滤层；泄水管设在集水井底部，泄水管下端伸入垫层下方土体中；泄水管侧壁上、位于土体中的部位上间隔开有泄水孔道；泄水管的管道内部填有膨胀混凝土芯，且膨胀混凝土芯的顶面低于泄水管的顶端；泄水管管道内部、位于膨胀混凝土芯顶面位置处设有封堵板；封堵板上方的泄水管中填有密封膏；止水板呈环状，焊接在泄水管的外侧壁上；碎石过滤层填充在泄水管的周围，且碎石过滤层的顶面与垫层的底面平齐；在碎石过滤层的外侧包裹有土工布。本发明解决了传统的底板预留降水管井施工工序复杂、后期易发生渗漏以及降水井在地下室主体结构施工期间被损坏或者停止运行的技术问题。
