Deep foundation pit dewatering method for strongly weathered sandstone stratum
The invention relates to a deep foundation pit dewatering method for a strongly-weathered sandstone stratum. According to the method, a dewatering well outside a deep foundation pit of the current strongly-weathered sandstone stratum is used for dewatering outside the deep foundation pit; and then light vacuum well point dewatering is added in the deep foundation pit of the strongly weathered sandstone stratum, and segmented dewatering excavation is carried out. The method is simple and easy to implement, high in speed and low in cost, does not affect the construction period, effectively solves the problems that the strong weathered sandstone stratum is rapidly softened after water permeation and precipitation outside the pit is difficult to achieve, and can be suitable for deep foundation pit precipitation engineering of the strong weathered sandstone stratum.
本发明涉及一种强风化砂岩地层深基坑降水方法，该方法是利用当前强风化砂岩地层的深基坑坑外降水井进行坑外降水；再在强风化砂岩地层的深基坑坑内增加轻型真空井点降水，并进行分段降水开挖。本发明简单易行，速度快、成本低，对工期不造成影响，有效解决了强风化砂岩地层透水后迅速软化、坑外降水难达效果问题，可适用于强风化砂岩地层深基坑降水工程。
