Abstract

Крепь дл  охраны подготовительных выработок м.б. использована в горной промышленности при охране подготовительных выработок с изготовлением крепи на месте производства работ из отформованных железобетонных блоков. Крепь выполнена в виде тумб из железобетонных блоков 1 квадратной формы, Блоки в центре имеют сквозное отверстие дл  установки фиксатора 2 общего дл  всех блоков тумб. Между кровлей и тумбой расположены податливые элементы 3. Верхн   и нижн   поверхности блоков имеют пазы, в которых размещаетс  гибка  св зь, например канат. 3 ил.Support for preservation workings m. used in the mining industry in the protection of preparatory workings with the manufacture of lining at the work site from molded reinforced concrete blocks. The support is made in the form of curbstones made of reinforced concrete blocks 1 of square shape. The blocks in the center have a through hole for fixing the clamp 2 in common for all blocks of pedestals. The pliable elements 3 are located between the roof and the pedestal. The upper and lower surfaces of the blocks have grooves in which a flexible connection is placed, for example a rope. 3 il.

Формула изобретенияClaim Крепь для охраны подготовительных выработок, выполненная в виде тумб, состоящих из уложенных друг на друга отдельных железобетонных блоков, рабочие поверхности которых имеют пазы, и податливых элементов, расположенных между кровлей пласта и верхним блоком, от лич а ю щ а яс я тем, что, с целью повышения устойчивости и несущей способности путем соединения всех железобетонных блоков в сплошную опорную полосу, крепь снабжена гибкой связью, например канатом, и осевым фиксатором, а каждый блок в центре имеет сквозное отверстие, через которое осевой фиксатор соединяет блоки по вертикали, а гибкая связь уложена в пазы рабочих поверхностей блоков.The support for the protection of the preparatory workings, made in the form of pedestals, consisting of separate reinforced concrete blocks stacked on top of each other, the working surfaces of which have grooves, and compliant elements located between the roof of the formation and the upper block, by the fact that , in order to increase stability and bearing capacity by connecting all reinforced concrete blocks into a continuous support strip, the lining is equipped with a flexible connection, for example, a rope, and an axial clamp, and each block in the center has a through hole through which howl connects latch blocks vertically, and the flexible connection is laid in the grooves operating units surfaces. | | — — t - - t 1 1 1 1 о about 1 1 1 1 1 4—· 1 4-· 1 1 - -4 - -4
