Description

The invention relates to construction and is intended for use in the erection of tower structures on an unevenly deformable foundation, namely, on undermined areas characterized by uneven vertical and horizontal deformations of the earth's surface caused by mining.

The foundation of the tower structure is known, which is a central support plate and cantilever elements rigidly connected to it, supported on clamps mounted on the outer foundation cushions 1.

The disadvantage of the known foundation is the possibility of uneven vertical and horizontal displacements of its elements during part-time work, which is unacceptable for tower-type structures.

The closest technical solution to the invention is the foundation of the tower structure,; erected on an unevenly deformable base, including a support part, on the upper end of which open niches for spacers are made open, and a base part 2.

The disadvantage of this foundation is that, after straightening the roll of the tower structure on an uneven

With the basement settled down, the supporting part of the foundation remains inclined, which leads to the appearance of additional efforts in these structures, as a result of which the straightening of the heel becomes difficult and the operation of the foundation is not reliable. .

The purpose of the invention is to ensure the reliability of the foundation work and to facilitate the straightening of the roll of the tower structure with uneven deformations.

The goal is achieved by the fact that in the foundation of a tower structure erected on an unevenly deformable foundation, including a support part,

FIG. 1 shows the foundation, n the cross section of the b-bf of FIG. 2; in fig. 2. - section A-A in FIG. one; in fig. 3 is a section b-B in FIG. 1. The foundation of the tower structure, erected on an unevenly deformable base, consists of a support part made of the inner 1 and outer 2 sections and a basement part 3. The inner section 1 is made with recesses 4 in which vertical L-shaped elements 5 are placed, the components of the outer section 2. The b shaped elements 5 are connected to the inner section 1 by vertically compliant connections 6. Between the L-shaped elements 5 and the inner section 1 are fixtures 7, for example, in the form of a package of thin metal plates ting. In the upper part of the L-shaped elements there are niches 8 for installation of spacer devices, for example jacks. Links b can be made in the form of horizontal anchor bolts. At the same time, the bondability, i.e. the possibility of vertical movement of the inner section 1 relative to the L-shaped elements 5 is ensured by the arrangement of the elongated holes in b. -shaped items. . The principle of operation of the foundation of a tower structure, erected on an unevenly deformable foundation, is as follows. To straighten the basement roll and the tower with weapons located on it, it is necessary to install spacers in niche 8, to apply pressure in the hydraulic system, to create between these L-shaped elements and internal section 1 a minimum clearance sufficient to adjust the clamps 7 (for example, metal plates, so that the top of the locks on the side opposite to the roll and on the side of the roll were at the same level). As a result of the subsequent decrease in pressure in the hydraulic system, the outer section 2 under the influence of the load from the tower structure, due to the incision of the inner section 1 into the base, is tilted in the opposite direction (roll to the support of the inner section 1 on the fasteners 7. In this connection 3, pliable in the vertical plane, do not prevent the inner section 1 from moving relative to the L-shaped elements 5. Thus, the foundation and the tower structure on it acquire a vertical position. The basement of the tower structure erected on an unevenly deformable base will increase the reliability of the tower structures in the undermined areas and facilitate the straightening of their roll. Invention The foundation of the tower is erected on an unevenly deforming base including the supporting part niches for spacers, and the basement part, about tl and h a and n and so that, in order to increase the reliability of the foundation and facilitate straightening the inclination of the tower structure with irregular base deformations, the supporting part is made of internal and external sections, the internal section is made with depressions on the surface, and the external section is made of vertical L-shaped elements placed in the internal sections of the internal section connected to the inner section by vertically flexible connections, and the niches for spacers are placed in each element of the outer section-.
