摘要
在深圳前湾填堤围堰工程中,由于挤淤厚度超过了国家规定的12m,难度较大。在施工中制定爆破挤淤施工工艺,选择适宜的爆破器材,精心设计挤淤参数和药包结构,并采用机械布设药包和导爆索电雷管起爆网路,最后达到理想的爆破挤淤效果。
The engineering of bank cofferdam of Qianwan town of Shenzhen faced great difficulty in the silt replacement owing to the silt thick exceeding the national critical thickness of 12m. For this reason,the replacement was projected to be carried out by blasting, using feasible blasting equipment, carefully de- signed replacement parameters and charge structure, and adopting mechanically laying charge and ignition network of electric detonator. The silt replacement reached its ideal effect by the blasting.
