“沙金沟,石夹沙,风化岩石天天塌,早也塌,晚也塌,一天塌过二十八”。这就是我们工地情况的写照。沙金沟的石质系数为6至8,石沙混合,互不附着,稍受外力即可塌落,从3月8日开工到10月20日结束,共塌方1100余次,每天平均有大大小小的塌方5次,最多一天塌到28次。平均每掘进一公尺就有二次以上的塌方。在这种情况下,我支队认真贯彻了多快好省安全保密的施工方针,提前超额一倍完成了任务,出现了七个长期无工伤连队,其中最突出的是机枪连,七个半月没发生一名工伤。他们所以取得这样优异的成绩,有以下几个
“Sha Jin ditch, sand stone, weathered rock every day collapse, early collapse, night also collapsed, one day fell twenty-eight ”. This is the portrayal of our site. Sha Jingou stone coefficient of 6 to 8, the sand mixed, not attached to each other, can be slightly affected by external collapse, starting from March 8 to the end of October 20, a total of more than 1,100 landslides, an average of every day large Small landslides 5 times, up to 28 times a day. On average, there is more than two landslides per meter of driving. Under such circumstances, our detachment conscientiously implemented the construction guideline of ensuring safety and secrecy in a more secure and efficient manner. We accomplished the task by exceeding twice in advance. Seven long-term non-work-harmed companies appeared, of which the most outstanding ones were machine guns and even seven and a half months An occupational injury occurred. So they achieved such excellent results, the following
