Изобретение относитс к области строительства , а имейно к конструкци м фундаментов гражданских и промышленных зданий и сооружений, возводимых в услови х вечномерзлых грунтов и в безмерзлотных зонах, в то.м числе методами намыва территорий дл сейсмических районов.The invention relates to the field of construction, and specifically to the construction of foundations of civil and industrial buildings and structures erected in permafrost conditions and in freezing zones, including the method of washing in areas for seismic areas.

Известны фундаменты столбчатые с башмаками или плитами, ленточные, свайные различных типов 1 .Known columnar foundations with shoes or slabs, belt, pile of various types 1.

Недостатком таких фундаментов вл етс невысока сейсмостойкость.The disadvantage of such foundations is low seismic resistance.

Наиболее близки.м техническим решение.м к данному изобретению вл етс фундамент, включающий полую коническую оболочку с опорным кольцом и соединенную с ней полую стойку 2 .The closest technical solutions to this invention are the foundation, which includes a hollow conical shell with a support ring and a hollow pole 2 connected to it.

Недостатками этих фундаментов также вл ютс невысока сейсмостойкость, а также отсутствие оптимальной статической работы.The disadvantages of these foundations are also low seismic resistance, as well as the lack of optimal static performance.

Цель изобретени - повышение сейсмостойкости и улучшение статической работы.The purpose of the invention is to increase seismic resistance and improve static performance.

Поставленна цель достигаетс те.м, что известный фундамент, включающий полуюThe goal is achieved by the fact that a well-known foundation, including a hollow

Claims

The foundation has a hollow conical shell 1 with a support ring 2 and a hollow rack 2 connected to it, having at the upper end of the caps 4, a piston 5 whose diameter is less than the diameter of cavity 6 of rack 3. Cavities 6 and 7 respectively of rack 3 and shell 1 are filled dry sand, a plunger 5 and a lower end 8 of the factory. en in the cavity 6 of the rack 3 and buried in the sand, the foundation. may have a SHEET gasket 9 of elastic-plastic material located under the supporting pad 2. Walls 10 and 11 respectively the support ring and the rack may have waterproofing Goes coating (not shown). The strut and shell, instead of a round section, may have a square or rectangular shape. A sheet of elastic plastic material is laid on the ground 12 and the support ring is supported on it. A conical shell is installed on the support ring on the cement mortar. In the upper nest 13 of the shell on the cement mortar installed stand. Between the piston and the internal cavity of the stand are placed felt or felted heat exchangers 14. Seals can be made of other suitable materials for this. The piston locks the load through the tip of the razdbalka 15 after the foundation has been installed on the underlying soil with the mark a, the soil is poured in or poured up to the desired mark b. The watertightness of the joints of the assembled 1) 1x structures of the foundation and the structures themselves is achieved by means of B1 complete waterproofing of unoxide resins with cured, h. The foundation works in the following way. The load on the foundation is transmitted through the top of the nor1in. The piston transfers this load to the sand, placed inside the cavity of the stand and the conical shell. The sand distributes the load on all the inner walls of the basement horizontally, vertically, up and down with directional components. Dry nesok promotes szh, agzhivaniya seismic vibrations. As a result, the distribution of the load, which is not interrupted by the piston, only about half of it falls on the supporting surface of the soil. This allows more than two times, but compared to pile of mn foundations, it is possible to replace the need for foundations by erecting a foundation. Claim 1. Fundamentals of a null conical shell with a support ring and connected to it a null rack, characterized in that, in order to improve seismic resistance and improve static work, it is equipped with ... meters on the upper m end of the heads, . The diameter of the KOTOpoio is smaller than the diameter of the cavity of the rack, and the STRIP and the shell and the rack are filled with sand, and the piston with the lower K01Shch is brought into the cavity of the rack and buried in the sand. 2. The Foundation of n. 1, characterized in that it is provided with an LR.STOVOY gasket made from an elastic-plastic material located under the support ring, and the walls of the outer ring of the shell and the stand are provided with a hydraulically insulated coating.
