Description

The present invention relates to the field of seismology, the field of construction of protective structures from the forces of the earthquake and, in particular, can be used to neutralize the forces of the earthquakes and reduce damage from its action.

Various causes of an earthquake are known. Most often, they arise as a result of the interaction of tectonic (lithospheric) plates, their impacts, contact stresses, pressures, etc. The pressure and stress waves arising in this case propagate in the earth in all directions, the most dangerous of which are waves propagating over the surface. Directly on the surface of the earth they create vibrations of buildings and subsequent destruction of objects rigidly fixed in the lower part.

There is a method of preventing earthquakes by local displacement of the earth’s crust in the direction of eliminating contact stresses between the transition phases of the earth’s bowels, which is carried out by a directional shot from a gun mounted on the earth’s surface, see RU 94040422, А62В 37/00 from 10.28.1994.

There is also known a method of dealing with earthquakes, including the installation in the central part of a multi-storey building, the so-called stiffener core in the form of a reinforced concrete pillar, see YouTube, Galileo, Earthquake-resistant buildings.

However, the known method protects only one building being erected and does not provide protection for other buildings, old buildings, as well as infrastructure located on earthquake-prone territory: highways, bridges, overpasses, etc. facilities.

The purpose of the creation of the present invention is to achieve a technical result for the protection of residential, industrial facilities and infrastructure in the territory from seismic forces.

The specified technical result for the method, including the installation of reinforced concrete rods in the center of the house, is ensured by pre-determining the zones of seismic activity, identifying the boundaries of the territory of the protected structures, infrastructure objects and in front of these boundaries, laying them vertically in the ground and laying them horizontally, perpendicular to the borders territories, neutralizers of seismic vibrations, while the neutralizers of subsequent rows are located between the neutralizers of the previous rowing row.

The specified technical result for a device containing reinforced concrete rods is provided by the fact that it contains seismic vibration detectors, with disks perpendicular to the longitudinal axes of the neutralizers, with reinforced concrete rods and with intermediate spring inserts.

The invention is illustrated in graphic materials.

In FIG. 1 shows the design of seismic vibration detectors, consisting of reinforced concrete rods with end disks at the ends and intermediate spring inserts located vertically and horizontally in the ground, in FIG. 2 shows a fragmentary top view of the location of the neutralizers in front of the border of the protected area.

A device that implements a method of neutralizing seismic vibrations includes:

1 - neutralizers;

2 - reinforced concrete rods;

3 - end disks.

4 - intermediate spring inserts.

A device that implements the claimed method consists of neutralizers 1 with end disks 3 at the ends, reinforced concrete rods 2 and intermediate spring inserts 4. The number of spring inserts 4 can be several - one, two, three, etc. Their number is determined by the availability of free space to accommodate the neutralizers 1 and the possibility of their transportation to the installation site. The neutralizers 1 are arranged in rows in front of the boundaries of the protected area, see FIG. 2, set vertically in the ground and laid horizontally, in the latter case, with the longitudinal axes perpendicular to the border of the territory. In this case, the neutralizers 1 of the second, from the boundary, the row are located between the neutralizers 1 of the first row, and the neutralizers 1 of the third row are installed in the spaces between the neutralizers 1 of the second row, etc.

The claimed method of neutralizing seismic vibrations is implemented as follows.

Preliminarily, according to statistical data, zones of seismic activity are determined, after which they allocate settlements, structures and infrastructure in this zone: power plants, railways, bridges, overpasses, etc. In the ground, on the outside of the protected territory, along its borders, in rows, neutralizers 1 of seismic vibrations are installed vertically and laid horizontally perpendicular to the borders of the territory, see FIG. 1. At the same time, the second row neutralizers 1 are located between the first row neutralizers 1, and the third row neutralizers 1 are installed between the second row neutralizers, see FIG. 2.

During an earthquake, in its center, there arises one or a series of power vibrations propagating in the earth's environment in various directions. The most dangerous of these are surface waves. When moving them, compression and / or shift of soil sections occurs depending on their density. When force impacts approach the protected area, force waves primarily create pressure on the first end disks 3 of the horizontally placed neutralizers 1. These forces compress the spring inserts 4, which alternately absorb and reduce the strength of seismic vibrations.

The force of the seismic waves directed deep into the earth's surface partially decays when moving away from the center of the earthquake, and partially reflects from harder layers of the soil and rises to the surface of the earth. These force effects are neutralized by the front surfaces of the first discs 3, the spring inserts 4 of the vertically mounted neutralizers 1. Further, the force effects are absorbed by the inner surfaces of the last end disks 3, see FIG. 2.

In addition to neutralizing earthquake forces, horizontally located neutralizers 1 in the earth strengthen sections of their longitudinal arrangement, which prevents the formation of cracks in the earth.

Thus, the effect of horizontal and vertical earthquake forces on buildings, structures and adjacent infrastructure in the protected area is significantly reduced.

In the breadboard version, made on the basis of the indicator of the height of the splash of the colored liquid in the vessel mounted on the stand, which applied calibrated strokes, the claimed invention has shown its effectiveness.

The claimed invention is new, previously unknown, which indicates its compliance with the patentability criterion - novelty.

The invention can be implemented at any construction company, which indicates its compliance with the patentability criterion - industrial applicability.
