【摘要】:在爆破工艺受限的除礁工程中,抗压强度达70 MPa以上礁石无法清除。针对这一问题,进行了多种疏浚设备和施工参数改进的试验研究。采用钻孔-布钢锭-凿岩-抓斗相结合的施工方法,成功清除了该抗压强度的礁石。
[Abstract]:In the reef removal project with limited blasting technology, the rocks with compressive strength of more than 70 MPa cannot be removed. In order to solve this problem, a variety of dredging equipment and the improvement of construction parameters were studied. The rock of compressive strength was removed successfully by the combined construction method of drilling, ingot, rock drilling and grab.
