DEVICE OF ANTI-FILTER SCREEN ON THE BASIS OF INJECTION TECHNOLOGY UNDER THE LAKE SUMP IN KYIV

Abstract

The publication shows that in Ukraine, on many objects, the issue of protecting the underground space from the aggressive influence of substances that are impregnated in groundwater in places with deep deposition of a waterproof layer is topical. Classical methods can not fully address such issues. In order to solve this problem, an injection technology of an anti-filtration screen arrangement developed by the authors is developed, which is carried out under field conditions under the pond-drainage of sewage in Kyiv. The basic general principles of designing technologies for arrangement of horizontal anti-filter screens under existing structures for the developed solutions are shown. The entire technological process of implementing a horizontal anti-filtration screen based on injection technology using horizontally-directed drilling and modified cement mortar solutions is sufficiently detailed.
