| 摘 要： | 井下巷道交岔点经常需要通过架设抬棚的方式过渡，由于交岔点断面大，抬棚跨度大，U型钢组合抬棚在大断面时采用半圆拱形式，造成内拱型棚棚腿过短，抬棚两肩处影响通过矿车，不适于大跨度使用。为充分利用U型钢组合抬棚的优点，在设计交岔点抬棚时，我们采用三心拱设计抬棚的内门棚，使抬棚肩窝处空间加大，能最大限度利用巷道断面，便于矿车通行，既能充分发挥U型钢组合抬棚的优点，也达到可靠的支护效果。

| Abstract: | the underground tunnels bifurcation point often need to pay by way of carrying tent erection into bifurcation point transitional, because big cross section, carry tent span, the U shaped steel combination in large sections carried tent when caused by semicircle arch forms, arched tent tent within a short, carry tent leg two shoulders influence through the harvesters, not suitable for large span use. To make full use of the tents of U shaped steel combination carded into the advantage, in design, bifurcation point up tents three hearts we adopted the tents of arch design, who carried JianWo carried tent to shed in space increases, can make the best use of traffic roadway section, facilitate harvesters, can give full play to the tents of U shaped steel combination carried the merits and achieve reliable supporting effect. |
