FIELD: construction. ^ SUBSTANCE: method to develop a hydraulic insulating layer of foundation pits consists in laying of a layer of material with low water permeability at the bottom and slopes of the foundation pit. The material with low water permeability laid at the bottom and slopes of the foundation pit is sludge of chemical water treatment of power plants. Besides, together with the sludge of chemical water treatment, coarse hygroscopic wastes are laid, which are selected from coarse wastes of woodworking industry, wastes of improvement, wastes of stubs rooting out. ^ EFFECT: reduced cost of foundation pits construction, improved ecological safety in recycling of chemical water treatment sludge of power enterprises. |
