METHOD FOR PROTECTING FOUNDATIONS OF BUILDINGS AND STRUCTURES AGAINST DYNAMIC EFFECTS IN SOIL AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2017 - IPC E02D31/08 

FIELD: construction.

SUBSTANCE: method for protecting the foundations of buildings and structures against dynamic impacts in soil includes making at a distance from the building or structure, along its structural elements subject to dynamic impacts, a trench by drilling wells with a screw without extracting soil to the surface. The diameter and depth of the wells are appropriately equal to the length and width of the protection device, and the drilling pitch is determined by the condition of at least two wells of the loosened soil per one protection device in the planned position. Thereinafter, the protection device is submerged in the formed trench with loosened soil by means of a vibratory pale hammer rigidly installed on the protection device fastening element made in the form of a steel plate and rigidly connected to the upper butt of the protection device to the entire well depth, so that the outer wall of the protection device with longitudinal windows is located on the side of the source of dynamic impact in the soil. Each subsequent protection device on the soil surface is preliminarily connected to the protection device already submerged in the soil by means of connecting the corresponding vertical T- and -shaped locking elements mounted on the lateral outer walls of the protection device, adjacent to the wall with longitudinal windows. After submerging all protection devices, they are connected to one another by hydraulic hoses via couplings with valves, located under the upper plug on the outer wall of the protection device. Two extreme protection devices are connected to an external vessel containing damping liquid, then the cavities of each submerged protection device are subsequently filled with the damping liquid via pipelines mounted on their upper plugs.

EFFECT: increasing the protection effectiveness of buildings and structures against dynamic impacts by installing in the soil the system of devices for protecting foundations of buildings and structures that reduce the intensity of impacts, increasing the reliability of the protection device performance.
