Precipitation construction method for existing basement bottom plate in high-water-head area
The invention relates to a dewatering construction method for an existing basement bottom plate in a high-water-head area. According to the method, the hole is pre-formed in the existing bottom plate, and the opening and closing device is placed, so that the watertightness of the bottom plate is ensured, the connection between the precipitation equipment and the bottom plate is enhanced, and the water head pressure can be prevented from breaking through the weak point of the hole. Meanwhile, drilling is conducted twice in the process of drilling to obtain the precipitation channel, and the situation that underground water in a high-water-head area causes dangerous cases after the precipitation channel is chiseled open is prevented. By arranging the pressure measuring pipe, the underground water level condition can be monitored in real time in the rainfall process, the height of the underground water head can be monitored at any time, and emergencies are prevented. According to the method, after the holes are formed in the existing basement bottom plate in the high-water-head area, the strong water stopping effect is achieved, sealing treatment is easy to conduct in the later period, the purpose of lowering the underground water head below the existing basement bottom plate in the high-water-head area can be achieved through the method, preparation is made for communication of subsequent new and old buildings, and high engineering practical value is achieved.
本发明涉及一种高水头区域既有地下室底板降水施工方法。该方法通过在已有底板上预开孔，并放置开闭装置，保证了底板的止水性，强化了降水设备与底板的连接，可防止水头压力突破开孔薄弱点。同时，在开孔得到降水通道的过程中采用两次钻孔，预防高水头区域地下水在降水通道凿开后造成险情。通过设置测压管，可在降水过程中实时监控地下水位情况，随时监控地下水头高度，防止突发情况。该方法在高水头区域既有地下室底板上开孔后具备较强的止水效果，后期易作封闭处理，通过此方法可以实现在高水头区域降低已有地下室底板下地下水头的目的，从而为后续新老建筑的联通做准备，具有较高的工程实用价值。
