爆破测振仪L20-S参与青化砭2号隧道进口监测线安全距离划定
Time:2017-03-23 Views:
新建青化砭2号隧道位于陕西省延安市青化砭镇,由中铁二十局集团蒙华铁路MHTJ-7标一工区负责此隧道的修建,于2015年12月22日距隧道口32m处开始进行爆破施工,而爆破施工诱发的振动效应,对爆区周边民房构成潜在威胁。为了确定钻爆施工对是否隧道口民房造成振动影响,四川交博环境检测公司使用L20-S型爆破测振仪于2017年3月15日和16日进行了2次爆破振动监测。通过每次6台仪器,共采集12组数据,划定隧道掘进方向与隧道口民房所在监测线的k和a,最终确定2015年的爆破振动是否对隧道口民房造成振动影响。
Pre:爆破测振仪L20的CMC证书通过复查换证
Next:交博环境进行威信县高天乡气体勘探爆破施工振动检测
