Изобретение относитс  к горной промышленности и подземному строительству, в частности , к механизации возведени  крепи.The invention relates to the mining industry and underground construction, in particular, to the mechanization of the construction of lining.

Известны устройства дл  приготовлени  бетонов путем смешивани  встречно движущихс  струй затворител  и сухих компонентов , выполненные в виде последовательно соединен1 ых двух камер, между которыми расположен ствол дл  ввода затворител  fl.Concrete preparation devices are known by mixing oppositely moving jets of dryer and dry components made in the form of series-connected two chambers, between which there is a barrel for introducing the freezeer fl.

Однако в таком устройстве поток бетонной смеси затормаживаетс  и необходима дополнительна  энерги  дл  дальнейшей транспортировки смеси.However, in such a device, the flow of the concrete mix is slowed down and additional energy is needed to transport the mix further.

Наиболее близким решением из известных  вл етс  устройство дл  приготовлени  на- брызгбетона, включающее бункер с дозирующим шнеком, смесительную камеру, трубопроводы дл  подвода воды и сжатого воздуха , материалопровод с соплом 2.The closest solution known is a device for preparing sprayed concrete, including a hopper with a metering screw, a mixing chamber, pipelines for supplying water and compressed air, a material pipeline with nozzle 2.

Однако при подаче воды в поток сухих компонентов, бетонна  смесь затвор етс  неполностью , что снижает качество набрызгбетона .However, when water is supplied to the stream of dry components, the concrete mix is not fully closed, which reduces the quality of the sprayed concrete.

Целью изобретени   вл етс  повышение качества набрызгбетонной смеси.The aim of the invention is to improve the quality of the sprayed concrete mix.

Это достигаетс  тем, что в трубопровое дл  подачи сжатого воздуха смонтирован водовоздушный смеситель.This is achieved by installing a water / air mixer in the pipeline for supplying compressed air.

На фиг. 1 изображено предлагаемое устройство , общий вид; на фиг. 2 дан разрез А-А на фиг, 1.FIG. 1 shows the proposed device, a general view; in fig. 2 shows section A-A in FIG. 1.

Устройство дл  приготовлени  набрызгбетона содержит ходовую часть 1, на которой установлен манипул тор вождени  сопла 2, бункер 3 с подающим шнеком 4 и смесительной камерой 5. К смесительной камере подведен трубопровод 6 дл  подачи сжатого воздуха , в котором смонтирован водовоздушный смеситель 7,соединенный с трубопроводом 8 дл  подачи воды.The device for preparing the sprayed concrete contains a chassis 1, on which the nozzle driving arm 2, a hopper 3 with a feed screw 4 and a mixing chamber 5 are installed. A flow line 6 for supplying compressed air is connected to the mixing chamber. 8 for water supply.

. К противоположному концу смесительной камеры присоединен материалопровод 9.. A material line 9 is attached to the opposite end of the mixing chamber.

Устройство работает следующим образом. Суха  бетонна  смесь подаетс  шнеком 4 из бункера 3 в смесительную камеру 5, где она подхватываетс  водовоздушным потоком, кото-рый образуетс  водовоздушным смесителем 7, смонтированным в трубопроводе 6,и направл етс  в материалопровод 9. При движении по материалопроводу бетонна  смесь затвор The device works as follows. The dry concrete mix is supplied by the screw 4 from the hopper 3 to the mixing chamber 5, where it is picked up by a water-air flow, which is formed by the water-air mixer 7 mounted in the pipeline 6, and is directed to the material pipeline 9.
