Abstract

A structure of pressure steel-reinforced-concrete (reinforced-concrete) water conduits in soft formations that are placed at slope consists of separate sections and has a tooth in basement part of sections. To increase stability at shear resistance of water conduits the tooth placed in the basement section at the beginning of each section is arranged at the back side with lug with horizontal surface on which basement part of the end section of the neighboring section rests, there basement part in zone of resting is made horizontal.

Description

The construction of pressure steel dams is also well-known. temperatures, (see Arshenevsky N.N. and Ven". Dr. "Hydrolektrostancii", M., Znergia, 1980, p. The proposed technical solution is explained on 354-355). drawings, where fig. 1 is shown longitudinally

The disadvantage of such a design is the reduction of hopes - a section of the water pipeline, in fig. 2 - node A, where: workability and shear resistance of water pipes in the condition of 1 - water pipe section; operating conditions, especially in complex geological 2 - temperature-sediment seam; under the conditions of heterogeneous soils, which is connected with the distribution of water pipes; digging intersectional seams and leaks, as well as 4 - backfilling; shifting of water pipes on a slope. 5 - a tooth in the foundation part at the beginning of the sec-

The invention is based on the task of raising the water supply; 6 - protrusion from the upper side of the tooth 5; pluation, improvement of conditions of joint work of sections 7 - horizontal surface of protrusion 6; water pipes with the ground and with each other, reduction 8 - the foundation part with horizontal opening of the seams, and in general, increasing the reliability of the surface of the final section above the work of water pipes. adjacent section.

The task is solved by the fact that the construction of pressure-reinforced reinforced concrete (reinforced concrete) of the proposed structure consists of separate (reinforced concrete) water pipes, which are located on the slope of sections 1, separated by temperature-sedimentary from soft soils, consist of separate sections and seams 2 , located on a slope on a base Z with a muscle-filled with soil, have in the foundation part of the soil and covered with soil 4. All sections 1 of ma- sections tooth located in the foundation part are tooth 5 with a horizontal base, located at the beginning of each of the section, made of the upper part in the foundation part at the beginning of each side with a protrusion with a horizontal surface, on the section from the upper side, with a protrusion 6 and horizontal - which the foundation part rests on with the final partial surface 7, on which the foundation link above the one rests section, in which the fundamental part 8 with a horizontal surface, the end part in the bearing zone is made horizontal of the section located above the adjacent section 1. with flax. Also, the horizontal surface 7 of the protrusion 6 is

In addition, the horizontal surface of the protrusion of the tooth 5 is made with a coating with low shear forces, on which the foundation part rests with end indicators (made of bitumen, plastic, metal, etc.). of the section located above the adjacent section of the water pipe with such a design, which provides a common reason, made with a coating of 3 low work of all sections 1 of the water pipeline, due to the fact that the shear indicators. foundation part 8 of the final section above

Between the set of distinctive features of the technical located section is based on the horizontal solution that is declared, and the technical result, the surface 7 of the protrusion 6 in the tooth 5 at the beginning below what is achieved, there is the following system of the causally located section, including involvement in co-effect relationships ties good work of the ground base 3, thanks to the tooth 5,

When supporting the foundation part of the end under the action of static and dynamic loads, the theme of each adjacent section located above the perature influences, due to the joint work of the sections of the water pipe on the horizontal surface of the protrusion of the water pipe 1 between themselves and with the soil of the foundation 3, the relief made in at the beginning of the foundation part, the dynamic characteristics of the lower section are improved, a common structure is achieved, stress equalization in the foundation, sharp operation of all sections of the water pipeline between themselves and from the foundation - a decrease in the mutual vertical and horizontal movements of the foundation and a sharp decrease in the mutual movements of the movements of sections 1 and reducing the possibility of sections of water pipes under the action of static, temperature opening of temperature-settling joints 2 between and dynamic loads, increasing the stability of sections 1, increasing shear resistance. At a shift, and a sharp decrease in the opening of temperatures - the execution of the horizontal surface 7 of the protrusion 6 from no-sedimentary seams in operating conditions. coating with low shear rates according to

When performed on the horizontal surface of the tooth, the conditions of movement on the surface of the 7-foot coating with low shear rates of the pre-foundation part 8 of the end section are improved above, the improvement of the conditions of movement on the surface of the finished section with temperature protrusions of the tooth of the foundation part of the end section is improved. In general, an increase in the reliability of perature loads is achieved. operation of water pipes in operational conditions.

Signs distinguishing the claimed technical solution are absent in other similar solutions.
