(5) VIBRATED FOUNDATION

The invention relates to construction, in particular to the structures of foundations for equipment. A vibroisolated foundation is known, which includes a bath and a support block installed in it, the gap between the walls of the bath and the support block being filled with gas under pressure. X The disadvantage of the known foundation is the low reliability of its operation and high material consumption. The most closest to the technical essence of the invention is a vibrated insulated foundation including a bath, self-contained: there is a support block and shock absorbers located between the support block and the bottom of the bath 2 in it. However, this foundation is characterized by high material intensity. The purpose of the invention is to reduce the material consumption of the foundation. The goal is achieved by the fact that in the aero-insulation foundation, which includes a bath, a support block installed in it and shock absorbers placed between the support block and the bottom of the bath, the bottom surface of the support block is made domed and the side walls in the lower part of the block are interconnected radially in advance. by connections. Figure 1 shows the foundation, a general view; Fig. 2 shows a section A-A on fi g, 1, the Foundation includes a support block 1 mounted through shock absorbers 2 on the bottom of the bath 3 The lower surface of the support block 1 is made in the form of a sphere or a dome k, At the base of the sphere or dome are Corrosion-protected horizontal straight linear radially stressed bonds 5, one end of which is fixed in a metallic

ring 6, located in the center of the base of the sphere or dome, and the other by means of the anchoring device 7, on the side surface of the support block 1. Part of the length of the radially stretched links 5 is located in the channels 8 passing through the support block 1. On the upper surface 9 equipment 10 is located under support equipment 1. Under equipment 10, a spherical rebar mesh 11 is located at the greatest possible distance from the spherical surface k, with radially stressed links 5 passing through the lower cells of the grid eleven,

The principle of operation of the foundation is as follows.

When stresses are created in horizontal radial stresses, couplings x 5, uniform tensile stresses form in the concrete near the upper surface 9 of the support block 1, under machine 1, and uniform compressive stresses near the spherical surface.

When a shock load is applied while the machine is running in the concrete of the support block 1, stresses of opposite sign are generated in places, which are subtracted from the initial stresses formed by radially stressed links 5, which positively affects the operation of the block

JTa for percussion machines allows to reduce the consumption of materials, reduce the time and cost of construction, control the tension of the tension reinforcement of the connections during the operation of the foundation, increase the durability of the foundation by adjusting the prestressing in the connection armature during the operation.
