For the considered hydrogeological conditions of the Kulikovo Pole museum complex, located in the Kimovsky district of the Tula region, there is no necessary design of the drainage system, the method of its construction and the calculation method to ensure the drainage of groundwater from the basement. A vertical drainage design and calculation method necessary for the normal operation of the Kulikovo Pole museum complex were proposed. The purpose of the work is to develop a drainage design and substantiate a method for calculating the drainage of deep basements using the example of the Kulikovo Pole museum complex. The proposed design of vertical drainage makes it possible to increase the reliability of the drainage system due to the installation of a filter bed and a geotextile winding. The calculation of the proposed vertical drainage design consists of determining the following positions: the radius of the depression curve (the influence of drainage away from the basement of the building); drainage flow rate; water inflow into the drain; reducing the pressure in the middle between the row drains, selecting vertical drainage pumps. The proposed drainage design, the method of its construction (a patent for the invention was received) and the calculation method were tested when draining the deep basements of the Kulikovo Pole museum complex. The created system drains excess groundwater and eliminates the “barrage” effect. It is noted that the construction of drainage systems currently underway requires careful consideration of the experience of design and operation of drainage systems of the previous period and the use of new promising, cost-effective solutions.
