合理地研究木支架的結構,改進技術,是提高木材使用效果,減少浪費,和避免傷亡事故的有效辦法之一。為此,煤炭部曾設計了一種能承受大壓力的新型支架——耐壓棚。實踐證明,這種利用原有木棚改製而成的耐壓棚,使用在大压力的巷道中,可以提高耐壓能力及服務時間三倍以上,從而大大地减少了坑木的消耗,節省了维护費用和人工,保證了巷道內工 A reasonable study of the structure of wooden scaffolds and improvement of technology is one of the effective ways to increase wood use efficiency, reduce waste, and avoid casualties. To this end, the Ministry of Coal has designed a new kind of stent that can withstand high pressure - pressure sheds. Practice has proved that this type of pressure shed made from the original wooden shed can be used in a roadway with high pressure, can improve pressure resistance and service time more than three times, thereby greatly reducing the consumption of pit wood, saving Maintenance costs and labor ensure the work in the roadway
