Description
и имеет в поперечном сечении форму арки, нижние концы которой 5 и 6 отогнуты под углом дл соединени с последующей оболочкой. По концам оболочки 2 и 3 имеют диафрагмы 7, выполненные заодно с оболочкой, в вершине оболочки соедин ютс болтами 8 посредством диафрагм 7 через упругую прокладку 9. Нижние концы оболочек соединены с основанием 10 через опоры 11 посредством упругих прокладок 12, диафрагмы 7 и штырей 13. Основание 10 состоит из двух частей, соединенных посредством накладок 14 и болтов 15. Основание 10 св зано с опорой 11 болтовым соединением 15 Отдельные секции крепи по основани м соединены св з ми 16.and has the shape of an arch in cross section, the lower ends of which 5 and 6 are bent at an angle for connection with the subsequent sheath. At the ends of the shell 2 and 3 have a diaphragm 7, made integral with the shell, in the top of the shell are connected by bolts 8 by means of diaphragms 7 through an elastic gasket 9. The lower ends of the shells are connected to the base 10 through the supports 11 by means of elastic gaskets 12, a diaphragm 7 and pins 13 The base 10 consists of two parts, connected by means of linings 14 and bolts 15. The base 10 is connected to the support 11 by bolted connection 15. Separate sections of the support along the bases are connected by links 16.
Пор док возведени крепи следующий .The erection of the roof is the next.
Крепь возводитс на прин тую длину щитового столба в несколько приемов . После проведени в лежачем боку пласта полевого штрека проход т рассечку на полную мощность пласта с присечкой пород кровли и почвы. Размер рассечки по простиранию принимают в зависимости от устойчивости угл к боковых пород кратным шагу ра мещени секций.The support is erected to the accepted length of the shield column in several steps. After the field drift is carried out in the lying side of the bed, the layer is cut to its full capacity with the rocks and roof rocks cut. Depending on the stability of the coal to the lateral rocks, the size of the dissection along the strike is taken as a multiple of the section size of the sections.
Дл установки опоры 11 на подошву полевого штрека укладывают элементы податливости 17 из лесоматериала , затем устанавливают опору 11, такую же опору 11 устанавливают в кровле пласта, далее устанавливают секции 1 по всей длине рассечки. К опорам 11 вначале креп т основание 10, затем через упругие прокладки 12 диафрагмы 7 и штыри 13 устанавливают перекрытие секции 1.To install the support 11 on the sole of the drift, pliability elements 17 made of timber are laid, then the support 11 is installed, the same support 11 is installed in the roof of the seam, then section 1 is installed along the entire length of the dissection. The supports 10 are first fastened to the base 10, then through the elastic gaskets 12 of the diaphragm 7 and the pins 13 set the overlap of section 1.
После установки секции 1 соедин ют между собой по основанию 10 свз ми 16 .After installation, section 1 is interconnected at the base with 10 links 16.
По основанию 10 устанавливаетс тротуар 18 дл прохода людей и устанавливают закладочный конвейер 19 или пневмотрубопровод дл возведени закладочного массива 20. Закладочный материал подают на щит 21 в промежутки между основанием 10 при помощи плужковых сбрасывателей 22, устанавливаемых на закладочном конвейере .Pavement 18 is installed at the base 10 for the passage of people, and a stowing conveyor 19 or a pneumatic duct is installed to erect the filling mass 20. The stowing material is fed to the shield 21 between the base 10 by means of plow dumpers 22 installed on the filling conveyor.
Опоры крепи со стороны кровли оИ почвы пласта упрочн ютс анкерной крепью 23.The roof supports on the side of the roof of the soil of the reservoir are strengthened by anchor bolts 23.
