Abstract
1. СПОСОБ ВОЗВЕДЕНИЯ НАБРЫЗГБЕТОННОЙ КРЕПИ, включающий подготовку, обработку породной поверхности пленкообразующим материалом и нанесение бетонной смеси, отличающийс тем, что, с целью увеличени сцеплени бетонной смеси с породами, в качестве пленкообразующего материала используют промоторы адгезии. 2. Способ по п. 1, отличающийс тем, что в качестве промотора адгезии примен ют алкилсиликонаты, например этилсиликонаты , а нанесение бетонной смеси производ т через 5-30 мин после обработки породной поверхности промотором.1. A METHOD FOR CONSTRUCTING A NABRIZBETONNY KREPI, which includes preparing, treating the rock surface with a film-forming material and applying a concrete mix, characterized in that, in order to increase the adhesion of the concrete mix with the rocks, adhesion promoters are used as film-forming material. 2. A method according to claim 1, characterized in that alkyl silicates, such as ethyl silicates, are used as an adhesion promoter, and the concrete mixture is applied 5-30 minutes after the treatment of the rock surface with a promoter.

Изобретение относитс к горной промышленности и может быть использовано при креплении подземных горных выработок набрызгбетонной крепью.The invention relates to the mining industry and can be used in the fastening of underground mining workings with concrete lining.
Известен способ возведени набрызгбетонной крепи, включающий подготовку породных стенок и кровли выработки путем тщательной очистки породной поверхности водой или водовоздушной смесью и укладку бетона методом набрызга 1.There is a method of erection of sprayed lining, including the preparation of rock walls and roof workings by thoroughly cleaning the rock surface with water or an air-water mixture and laying the concrete using the spray method 1.
Известен также способ возведени набрызгбетонной крепи, включающий предварительную обработку породной поверхности жидким стеклом и последующее нанесение сло бетона 2.There is also known a method of erecting sprayed lining, which includes pre-treatment of the rock surface with liquid glass and the subsequent application of a layer of concrete 2.
Недостатком указанных способов вл етс невысока степень сцеплени наносимой бетонной смеси с породой.The disadvantage of these methods is the low degree of adhesion of the applied concrete mix with the rock.
Цель изобретени - увеличение сцеплени наносимого бетона с породами.The purpose of the invention is to increase the adhesion of applied concrete to rocks.
Цель достигаетс тем,.что согласно способу возведени набрызгбетонной крепи.The goal is achieved by the fact that according to the method of erecting sprayed concrete lining.
включающему подготовку, обработку породной поверхности пленкообразующим материалом и нанесение бетонной смеси, в качестве пленкообразующего материала используют промоторы адгезии, при этом нанесение бетонной смеси осуществл ют через 5-30 мин после обработки породной поверхности промотором.including preparation, treatment of the rock surface with a film-forming material and application of the concrete mix, adhesion promoters are used as the film-forming material, while applying the concrete mix 5-30 min after the treatment of the rock surface with the promoter.
Способ осуществл етс следующим образом .The method is carried out as follows.
Перед креплением горной выработки ее стенки очищаютс от пыли и гр зи. На очищенную породную поверхность опрыскивателем наноситс слой промотора адгезии , например этилсиликоната. Через 5- j 30 мин на подготовленную таким образом породную поверхность послойно наноситс бетонна смесь с помощью мащины БМ-60 или БМ-68.Before mounting the mine workings, its walls are cleaned of dust and dirt. A layer of adhesion promoter, for example ethyl silicate, is applied to the cleaned surface of the rock by a sprayer. After 5 to 30 minutes, the concrete mixture prepared in this way is applied in layers in layers using a BM-60 or BM-68 maschine.
Применение предлагаемого способа нанесени набрызгбетонной смеси позвол ет 0 повысить сцепление наносимого бетона, с породами.The application of the proposed method of spraying a concrete mixture allows 0 to increase the adhesion of the applied concrete to the rocks.
