Изобретение относитс ч горному делу, а именно к креп м капитальных горных выработок..The invention relates to mining, namely to the fortifications of capital mine workings.
Известна сборно-монолитна крепь, включающа железобетонные блоки пр моугольной формы с продольными канавкд и на торцовых поверхност х, замоноличиваемые введением в указанные канавки цементно-песчаного раствора 1 .Collapsible-monolithic lining, including rectangular reinforced concrete blocks with longitudinal grooves and on end surfaces, embedded with the introduction of cement-sand mortar 1 into these grooves is known.
Недостатком такой крепи вл етс отсутствие податливости перед saiMOноличиванием .The disadvantage of this support is the lack of compliance before saiMolocation.
Известна также сборно-монолитна крепь, состо ща из криволинейных железобетонных блоков, замоноличиваемых бетоном 2.Also known is monolithic reinforced lining, consisting of curvilinear reinforced concrete blocks, embedded in concrete 2.
Недостаток этой крепи заключаетс также в отсутствии у железобетонных .блоков пЬдатливости перед их замоноличиванием .The disadvantage of this support also lies in the lack of strength of the reinforced concrete blocks before they are monolithic.
Цель изобретени - придание железобетонным блокам податливости: пере их замоноличиванием.The purpose of the invention is to give reinforced concrete blocks compliance: re-embed them.
Это достигаетс тем, что блоки выполнены из двух Г-образных железобетонных элементов, конгруэнтно размещенных относительно друг друга и соединенных между собой арматурными стержн ми, образующими гибкую решетThis is achieved by the fact that the blocks are made of two L-shaped reinforced concrete elements that are congruently placed relative to each other and interconnected by reinforcing bars forming a flexible screen
ку, и снабжены двум узлами податливости , выполненными в виде Х-образно пересекающихс парных стержней, размещенных на стыке Г-образных элементов .and provided with two nodes of compliance, made in the form of X-shaped intersecting paired rods, located at the junction of the L-shaped elements.
На фиг.1 изображена сборно-монолитна крепь (лева половина до срабатывани узлов податливости, права - после осадки крепи и ее замоноличивани ); на фиг.2 - железобетонный блок с узлами податливости.Fig. 1 shows composite-monolithic lining (the left half before the activation of the nodes of compliance, the right - after the precipitation of the lining and its monolithing); figure 2 is a reinforced concrete block with nodes nodes.
Сборно-монолитна крепь состоит из криволинейных железобетонных блоков 1. Каждый блок включает два Гобразных железобетонных элемента 2, конгруэнтно размещенных относительно друг друга.Элементы 2 соединены между собой арматурными стержн ми 3,образующими гибкую решетку, а также двум узлами податливости 4, выполненными в виде Х-образно пересекающихс парных стержней. Арматурные стержни 3 и узлы податливости всех блоков замоноличены набрызг - бетоном 5. Закрепное пространство 6 затампонировано раствором.Precast monolithic lining consists of curved reinforced concrete blocks 1. Each block includes two Artificial reinforced concrete elements 2, congruently placed relative to each other. X-shaped intersecting paired rods. The reinforcement rods 3 and the nodes of compliance of all the blocks are monolithic sprayed with concrete 5. The fixture space 6 is tamped with mortar.
Возведение крепи и ее работу осуществл ют следующим образом1The construction of the lining and its work is carried out as follows
В забое проводимой выработки устанавливают крепь из криволинейныхIn the bottom of the ongoing development set the lining of curvilinear
