Description
Изобретение относитс к строитель- ному производству и горному делу и может быть применено, например, дл укреплени стенок скважин, образованных в горных породах.The invention relates to construction and mining, and can be applied, for example, to strengthen the walls of wells formed in rocks.
Известен способ формовани трубопроводов в грунте, включающий проходку скважины и заполнение ее материалом , из которого формуют стенки трубопровода, а дл образовани трубопроводов больших диаметров перёд проходкой скважины в грунте образуют полость и укрепл ют ее стенки, которые вл ютс сводом формуемого трубопровода 1 .There is a known method of forming pipelines in the ground, including drilling a well and filling it with the material from which the walls of the pipeline are molded, and to form pipelines of large diameters, they form a cavity in the soil and reinforce its walls, which are the vault of the formable pipe 1.
Однако дл данного способа характерна недостаточно высока прочность оболочки при изготовлении трубопроводов больших диаметров, что приводит к необходимости предварительного создани свода.However, this method is characterized by an insufficiently high shell strength in the manufacture of large-diameter pipelines, which leads to the need to pre-create a vault.
Известен также способ формировани трубопроводов в грунте, включающий формирование трубопроводов в грунте из пластичных бетонных смесей , которыми предварительно заполн ют скважины, а с целью обеспечени лучшего формообразовани трубопровода в качестве фО1 1ующего материала берут сухую смесь, которую нагнетают в сквс1жину влагосодержащим газом 2 .There is also known a method of forming pipelines in the ground, which includes the formation of pipelines in the soil from plastic concrete mixtures that are pre-filled with wells, and in order to ensure the best formation of the pipeline, a dry mixture is taken as the FOI1 material, which is pumped into the well with moisture-containing gas 2.
Недостатком зтого способа вл етс ограниченна возможность повышени прочности оболочки, изготовленной с помощью радиального уплотнени ее стержнеобразным рабочим органом, который имеет ограниченную силу удара.The disadvantage of this method is the limited possibility of increasing the strength of the shell made by radially sealing it with a rod-like working body, which has a limited impact force.
Наиболее близким к предлагаемому Closest to the proposed
10 по технической сущности и достигаемому эффекту вл етс способ изготовлени оболочки в выработке, заключающийс в том, что по длине выработки размещают зар д ВВ, который окружа15 ют самотвердек цим материгшом и подрывают его 3.10, by its technical essence and effect achieved, is a method for producing a shell in a mine, which consists in placing a charge of explosives along the mine length, which surrounds the self-hardening material and undermines it 3.
Недостатком данного спрсоба вл етс невысокое качество получаемой The disadvantage of this process is the low quality of the resulting
20 оболочки, так как вокруг выработки образуетс система радиальных трещин.20, since a system of radial cracks is formed around the excavation.
Цель изобретени - повышение качества оболочки в выработке.The purpose of the invention is to improve the quality of the shell in the development.
Поставленна цель достигаетс тем, The goal is achieved by
25 что согласно способу выработку заполн ют Сс1мот.вердеющим материалом (бетоном ) , из которого формуют стенки оболочки, затем в выработки ввод т зар$ш взрывчатого вещества (ВВ), ко30 торый предварительно помещсцрт в плас25 that, according to the method, the production is filled with CC1model with a hardening material (concrete) from which the walls of the shell are molded, then a charge of an explosive (EX) is inserted into the excavation, which is preliminarily placed
