Abstract
The solution of the problem of protecting buildings and structures from flooding has been relevant for many decades. An effective way to protect buildings and structures from groundwater is the installation of anti-filtration screens. The developed technology of construction of a protective soil-concrete impervious screen under the building with the use of auger equipment is described. The protective antifiltration primer-concrete screen is formed by mixing a partially developed base soil with hardening solutions. After excavation, the bi-directional auger, rotating in the opposite direction, transports the mortar to the center and simultaneously mixes the soil with the solutions. As a result of mixing, a soil-concrete screen is formed between the guide wells under the existing building or structure. The selection of the protective soil-concrete screen compositions built with auger equipment was carried out. A plan of experimental studies of the composition of the protective soil-concrete screen mortar is made up. In the developed technology, the screw is located perpendicular to the guide wells and is used for the development, transportation and mixing of soil with mortars. The methodology for conducting experimental studies of the composition mortar, the equipment and materials used are given. Mortars consist of water, cement and additives of basalt fiber, bentonite clay and liquid glass. Evaluation of the plastic strength of the mortar compositions was carried out on a Rebinder plastometer, upgraded with electric drive. The results of the plastic strength of the mortar composition with different percentages of additives contents. When analyzing the effect of these additives, the structure formation curves of the 11th composition with the highest percentage of basalt fiber, the 4th composition with the highest percentage of bentonite, and the 2nd composition with the largest percentage of liquid glass were constructed. The graphs are analyzed and the composition with the highest percentage of liquid glass showed the most intense curing. These studies can then be used to draw up technological maps of a protective soil-concrete screen construction under the structure.
