Изобретение относитс  к области подземноного строительства, вчастности устройствам дл  креплени  выработок набрызг-бетоном.The invention relates to the field of underground construction, in particular, to devices for fastening workings of sprayed concrete.

Известны сопла дл  нанесени  набрызг-бетона , включающие ствол и обхватывающую его втулку с каналами, корпус и распределитель воды.Spray-concrete nozzles are known, including a barrel and a sleeve with channels, a housing and a water distributor.

Цель изобретени  - снижение запыленности в рабочей зоне.The purpose of the invention is to reduce dust in the work area.

Достигаетс  это тем, что на обхватывающую ствол втулку установлена гильза с патрубком дл  отвода воздуха, причем полость, образованна  гильзой и втулкой, сообщена с каналами втулки.This is achieved by the fact that a sleeve with a nozzle for exhausting air is installed on the sleeve engaging the sleeve, and the cavity formed by the sleeve and the sleeve is in communication with the channels of the sleeve.

На фиг. 1 изображено предлагаемое сопло, продольный разрез; на фиг. 2 - поперечное сечение по А-А на фиг. 1; на фиг. 3 - сечение по Б-Б на фиг. 1.FIG. 1 shows the proposed nozzle, a longitudinal section; in fig. 2 is a cross section along A-A in FIG. one; in fig. 3 is a section along BB in FIG. one.

Сопло дл  нанесени  набрыэг-бетона состоит из ствола 1 и обхватывающей его втулки 2 с каналами а, корпуса 3 и распределител  4 воды.The nozzle for applying base concrete consists of the barrel 1 and the sleeve 2 surrounding it with the channels a, the body 3 and the distributor 4 of water.

На втулку 2 установлена гильза 5, причем полость В, образованна  гильзой и втулкой.A sleeve 5 is installed on the sleeve 2, the cavity B being formed by the sleeve and the sleeve.

сообщена с каналами а втулки. Гильза 5 имеет патрубок 6 дл  отвода воздуха.communicated with the channels and bushings. The sleeve 5 has a pipe 6 for exhausting air.

Работает сопло следующим образом.The nozzle works as follows.

Смесь воздуха, цемента и заполнител  из материального шланга, соединенного с корпусом 3 сопла, увлажненна  до необходимого В/Ц в распределителе воды, поступает в ствол 1. При прохождении ствола часть воздуха с частицами пыли через каналы а ствола и втулку поступает в полость В между втулкой 2 и гильзой 5, откуда через патрубок 6 отводитс  в пылесборник.The mixture of air, cement and aggregate from the material hose connected to the nozzle body 3, humidified to the required W / C in the water distributor, enters the barrel 1. When the barrel passes, some air with dust particles passes through the channels of the barrel and the bushing enters the cavity B between sleeve 2 and sleeve 5, from where it goes through pipe 6 to the dust collector.

Предмет изобретени Subject invention

Сопло дл  нанесени  набрызг-бетопа, включающее ствол и обхватывающую его втулку с каналами, корпус и распределитель воды, отличающеес  тем, что, с целью снижени  запыленности в рабочей зоне, на обхватывающую ствол втулку установлена гильза с патрубком дл  отвода воздуха, причем полость , образованна  гильзой и втулкой, сообщена с каналами втулки.A spray nozzle, comprising a barrel and a sleeve with channels, a housing and a water distributor, which, in order to reduce dust in the working area, has a sleeve with a branch pipe for air exhaust, with a cavity formed sleeve and sleeve connected to the channels of the sleeve.
