Description
{54} УСТРОЙСТВО ДЛЯ СООРУЖЕНИЯ ОПУСКНОЙ КРЕПИ ИЗ МОНОЛИТНОГО БЕТОНА Изобретение относитс к креплению шахтных стволов, в частности к устройствам дл сооружени опускной крепи из монолитного бетона, и может исподтьэоватьс при кредлении устьев и верхней части шахтных стволов в неустойчивых породах и плавунах. Известно устройство дл возведени крепи из монолитного бетона,вкл чающее переставную дерев нную опалу ку 1. Недостатком таких устройств вл етс вшсока трудоемкость и зн.а чительные затраты времени на уставо ку и разборку опалубки. Известно также устройство дл со оружени крепи, включающее несущую рамную конструкцию, опалубку в виде наружного и внутреннего колец и силовые домкраты, штоки которых иаправлены в пространство между кольцами опалубки f2l. В этом устройстве кольца опалубки передвижные, что требует значительных затрат времени на ее перест новку. Цель изобретени - снижение тру .доемкости сооружени опускной крейи Дл достижени этой цели наружное кольцо опалубки неподвижно закреплено в форшахте, а внутреннее жестко св зано с несущей рамной конструкцией и установлено на одном уровне с наружным кольцом. На чертеже схематически изображено устройство дл сооружени крепи из монолитного бетона. Устройство включает форшахту 1, соединенную со смонтированной над ней несущей рамной конструкцией 2. Внутри форшахты на уровне нулевой отметки установлена опалубка, наружное кольцо 3 которой соединено неподвижно с форшахтой при помощи анкерных болтов 4, а внутреннее кольцо 5стационарно подвешено на т гах 6к несущей рамной конструкции 2, к которой также прикреплены гидроцийиндры 7,предназначенные дл вьадавливани образуемого опускного колодца 8 Сооружение крепи из монолитного бетона начинаетс с возведени ее в пределах форшахты 1. При этом внутреннее кольцо 5 опгилубки опускают до уровн ножевого кольца 9, установленного на уровне основани форшахты, и бетонируют первое кольцо крепи.{54} MONOLITHIC CONCRETE DEVICE FOR BUILDING LIFTING STRAPES The invention relates to securing mine shafts, in particular, devices for building monolithic concrete sinking roofs, and may be used to crush the mouths and the top of mine shafts in unstable rocks and floats. A device for the erection of reinforced concrete supports is known, which includes a restoring wooden opal 1. The disadvantage of such devices is the high labor intensity and significant time spent on the installation and dismantling of the formwork. It is also known a device for the installation of lining, including a supporting frame structure, a formwork in the form of outer and inner rings and power jacks, the rods of which are directed into the space between the rings of formwork f2l. In this device, mobile formwork rings, which requires a considerable amount of time for its re-installation. The purpose of the invention is to reduce the labor capacity of the construction of the descending cradle. To achieve this goal, the outer ring of the formwork is fixed in the forchacht, and the inner one is rigidly connected to the supporting frame structure and is installed flush with the outer ring. The drawing schematically shows a device for the construction of supports of monolithic concrete. The device includes a forshaft 1 connected to a supporting frame 2 mounted above it. Inside the forshahta there is a formwork at the level of the zero mark, the outer ring 3 of which is fixedly connected to the forshahta using anchor bolts 4 and the inner ring 5 is permanently suspended on the tracks 6k of the supporting frame 2, to which the hydraulic jacks 7 are also attached, intended for pressing the formed draw well 8. The construction of the support from monolithic concrete begins with its erection within the forshakhty 1. When that the inner ring 5 is lowered to a level opgilubki blade ring 9 mounted on the front shaft of the base level, and concreted first ring support frame.
