Изобретение относитс к креплению горных выработок, а именно к анкерной крепи дл использовани преимущественно в обводненных проводах.The invention relates to the fastening of mine workings, in particular to anchor supports for use mainly in watered wires.

Известна анкерна канатна крепь, включающа помещаемую в скважину ампулу с химическим закрепителем, стопорное устройство, удерживающее ампулу в скважине и оголовок, установленный на выступающем конце каната 1.Known anchor cable lining includes a vial with a chemical fixative placed in a well, a locking device that holds the vial in the well and a cap mounted on the projecting end of the rope 1.

Однако така крепь вл етс конструктивно сложной, дорогосто щей и рассчитана на применение только в глубоких скважинах.However, such supports are structurally complex, expensive and designed to be used only in deep wells.

Известна также друга анкерна канатна крепь, включающа установленную в скважине дерев нную пробку с желобами дл каната и опорную плитку 12.Also known is another anchor cable lining, which includes a wooden plug installed in a well with a cable groove and a support tile 12.

Недостатком такой крепи вл етс мала несуща способность, котора создаетс только за счет набухани дерев нной пробки, повышенна трудоемкость установки, так как пробку с канатом надо вводить при помощи трубы или забойника, а также сложность возведени в сильно обводненных скважинах, поскольку пробка выталкиваетс водой еще до момента ее разбухани .The disadvantage of this support is the low carrying capacity, which is created only due to the swelling of the wooden plug, the increased laboriousness of the installation, since the cable plug must be inserted using a pipe or a bollard, as well as the difficulty of erection in heavily watered wells, because the plug is pushed out with water until it swells.

Цель изобретени - повышение несущей способности крепи и снижение трудоемкости ее установки.The purpose of the invention is to increase the carrying capacity of lining and reduce the complexity of its installation.

Цель достигаетс тем, что дерев нна пробка имеет выступающий из скважины конец и снабжена клином с желобом на торце дл каната, а опорна плитка жестко соединена с концами каната.The goal is achieved in that the wooden plug has a protruding end from the well and is provided with a wedge with a groove at the end of the rope, and the support tile is rigidly connected to the ends of the rope.

На фиг.1 изображена анкерна канатна крепь, общий вид; на фиг.2 разрез А-А на фиг.1; на фиг.З - разрез Б-Б на фиг.I.Figure 1 shows anchor rope lining, general view; in Fig.2 a section aa in Fig.1; on fig.Z - section bb in fig.I.

Claims

Anchor rope lining consists of wooden cork 1 of pressed wood with a longitudinal slit 2, which is fixed in the borehole 3 by means of a wedge 4 and a rope 5, which bends around the cork 1 along chutes 6 and 7 and the wedge gutter 4. The ends of the rope 5 are rigidly clamped in support plate 8. Cork 1 has a protruding end. The main bearing element is rope 5, and wooden plug I, swelling in moist rocks, increases the bearing capacity of the roof supports. Anchor rope lining works as follows. The pressure of the displaced roof is transmitted through the support tile 8 and the rope 5 onto the wedge 4. As the pressure ages, the strut of the cusps 1 and the wedge 4 and, consequently, the carrying capacity of the lining increases. When installing, a cork with a wedge and a rope laid in their complaints is inserted into the well as far as the supporting tile against the roof and wedged with several blows to the projecting end of the cork. The rope can be made of various materials (new or used cable, wire, etc.). Rigid fastening of the canal to the base plate can be done in various ways (clamp welding, wedging, knot, etc.). The wedge with a groove can be made of metal or other wood sorits. The wood stopper is cast out of any wood with high swelling capacity. Cork can be made of several links. At the same time, the last link is fixed at the wellhead. 5 The presence of a wedge with a groove and a rope rigidly attached to the baseplate makes it possible to simultaneously secure the anchor and pull the rope when the plug is plugged. The presence of a wooden plug with a protruding end eliminates the need to use an installation pipe or a rammer, increases the bearing capacity of the support by increasing the contact area with the walls of the well and prevents the destruction of the lower layers of the roof. Claims Anchor lining, comprising a wooden plug installed in a well with a rope groove and a support tile, characterized in that, in order to increase the bearing capacity of the lining and reduce the labor intensity of its installation, the wooden plug has a protruding end from the well and is fitted with a wedge the gutter at the end of the rope, and the support tile is rigidly connected to the ends of the rope.
