По этим причинам в некоторых случаях проблемы, связанные с понижением и контролем уровня грунтовых вод во время земляных работ, могут оказаться наиболее важными и трудно решаемыми. Для выбора и правильной оценки размеров системы обезвоживания, как временного, так и постоянного, исключительно большое значение имеет предварительное обследование для точного определения гидрогеологических условий района проведения земляных работ. Wellpoint dewatering method consists in using often located wells with tubular water inlets of small diameter for water intake from the soil - wellpoints connected by a common suction (in the case of light wellpoints) or pressure (in the case of ejector wellpoints) collector with a central (for a group of wellpoints) pumping unit ... Wellpoint borehole systems are usually successfully used to lower and control the groundwater level in loose soils that are permeable through pores (silt, sand, fine gravel). It is in soils of this type that pore (or unbound) water occurs, and therefore hydrodynamic phenomena are observed.
