Lowering the groundwater level in the areas of influence in the recessed structure

The underground space large cities placed recessed structures, foundations, basements, transport facilities, warehouses, network engineering, industrial and energy objects. Zaglublyuyuchis below the groundwater level, the recess, causing the influx water itself. Water can do destructive work. It is capable of its hydrodynamic effect to capture with a soil, leading quicksand in its state, thereby dislodging the bottom and the collapse of the slope located above the other parts. Proceeding from the bottom excavation, water weighs soil loosens it and can make unusable as the base facilities. It aggravates and complicates the production of land, installation and other construction work in the pit. This article provides guidance on the selection of reduction method the groundwater level in the areas of their influence on zagliblublennye facilities.
