Charging valve of garbage chute // 2614390
FIELD: construction.SUBSTANCE: charging valve of the garbage chute includes the chamber for placing the garbage bag therein and the device for introducing the garbage bag into the window of the vertical garbage chute composition. The stationary chamber for placing the garbage bag therein is made in the form of a parallelepiped with the inclined slippery bottom at an angle of more than 45%, wherein the toe of the inclined slippery bottom is extended up to the contact line with the window of the vertical garbage chute composition, the chamber turning cover is provided with a retractable rod ending with a flexible plate to push the garbage bag into the window of the vertical garbage chute composition. The passage rod sleeve is located on the cover closer to the garbage shaft. In the flange connection of the chamber to the passage insert of the vertical garbage chute composition, the flexible plate with flexible vertical stripes across the entire passage section is fixed.EFFECT: increasing the charging valve efficiency and reliability.2 dwg

ethod and system to push and transport solid wastes // 2492303
FIELD: construction.SUBSTANCE: method to transport solid wastes from at least one retention zone into at least one header pipeline or at least to one station of wastes collection comprises a stage of solid wastes dispatch from each retention zone to a transportation pipeline, and additionally includes the following stages: (a) pushing and transportation of solid wastes in the transportation pipeline towards the specified at least one header pipeline or at least one wastes collection station with the help of a transportation facility by creation of pressure difference at different sides of the specified transportation facility with provision of pushing and transportation of the specified solid wastes towards the specified at least one wastes collection station or to the specified at least one header pipeline and (b) control of the specified transportation facility with the purpose of its return to initial position. At the same time return of the specified transportation facility to its initial position is carried out by creation of pressure difference at different sides of the specified transportation facility to ensure displacement of the transportation facility from the specified at least one wastes collection station or the specified at least one header pipeline into its initial position. Also a system is described for transportation of solid wastes from at least one retention zone, as well as the method of solid wastes transportation from at least two retention zones and a system for transportation of solid wastes from at least one station of wastes origination.EFFECT: reduced power consumption, reduced initial capital investments, increased efficiency of wastes removal.31 cl, 10 dwg

Trash chute shaft section // 2375530
FIELD: construction industry.SUBSTANCE: invention refers to construction industry, and namely to design of trash chute sections ensuring removal of domestic waste from buildings, but can also be used as section of assembled ventilation shaft of the building or construction. Trash chute section is made in the form of pipe with connecting broadening on one end from fibre-glass laminate consisting of several layers of glass-cloth or/and glass mat and hard-combustible bonding agent applied between glass-cloth layers. Between internal and external tube layers made in the form of shells there installed is zigzag-shaped corrugated filler contacting and connected with its protrusions to the above layers due to the bonding agent applied to glass-cloth and forming together with internal and external tube layers the through zigzag-shaped channels.EFFECT: increasing strength of structure at simultaneous decrease of its weight, and as well as increase of thermal insulating properties of trash chute section and its durability owing to condensate moisture being discharged.8 cl, 5 dwg

Refuse chute for high multistory residential and office building // 2302499
FIELD: construction, particularly arrangements in buildings for the disposal of refuse.SUBSTANCE: refuse chute for multistory building comprises shaft with loading gates at each story and damping device, which reduces gravitational speed of solid refuse loaded in the chute. The damping device is installed along chute axis at intermediate building story and retained with support. The damping device is shaped as semi-loop smoothly bending from chute shaft axis. The semi-loop has diameter and flexure equal to shaft diameter. The semi-loop is formed of separate singly-type branches provided with flanges to connect sections with each other, refuse chute and support.EFFECT: decreased gravitational speed of solid refuse and, as the result, decreased noise propagation over building and improved safety, as well as increased simplicity and reliability and reduced costs.3 cl, 9 dwg

Refuse chute shaft section // 2299959
FIELD: construction, particularly refuse chutes to remove domestic waste and ventilation shafts of building or building structure.SUBSTANCE: refuse chute shaft section is made as laminated fiberglass plastic pipe of cylindrical shape and preferably provided with widened end section. The pipe includes at least three fiberglass plastic layers formed by winding solid glass tissue webs and/or glass mats having widths of not less than 0.9 m and/or cut into rolls having widths of not less than 0.05 m on shaping mandrel. Fire-resistant binding agent having life of not less than 6.5 hours at 18-25°C temperature is applied between fiberglass plastic layers during winding thereof on shaping mandrel. Fire-resistant binding agent is mixture including 100 parts by weight of polyester resin and 0.8-2.5 parts by weight of methylethylkonate or 1.0-3.0 parts by weight of cyclohexane taken in amount enough to impregnate inner layers of refuse chute shaft section. Glass tissue webs are wound in several strips along section length and overlap each other along helical line so that each next turn overlaps previous turn for width of not less than 0.2 of glass tissue web width to be wound on shaping mandrel. During refuse chute assemblage the first wound strip is the uppermost one. Glass tissue webs may be wound in several strips so that strips of adjacent layers are oriented in opposite directions. Glass tissue webs may be also wound in several serial overlapped annular strips located along section length. The annular strips are located so that each next strip overlaps previous one for not less than 0.1 of glass tissue web width. During refuse chute assemblage the first wound strip is the uppermost one. Glass tissue layers may be wound on shaping core in alternating mode and include ones formed by helical and annular strips. Glass tissue web width is equal to refuse chute shaft section height.EFFECT: increased efficiency of refuse chute usage due to decreased inner surface damage caused by impact action to be applied thereto during refuse chute usage, improved sanitary efficiency, enhanced assemblage conditions and increased maintainability of refuse chute shaft sections.6 cl, 1 dwg
