复杂工况下老闸拆除爆破试验研究

Experimental study of blasting demolition of an old floodgate in complicated environment

对于复杂工况下的钢筋混凝土结构拆除,是具有一定的技术难度的。介绍了针对泉港老闸复杂工况而作的试验研究工作。试验成果经现场调整与复核,较好地应用于现场施工,保证了爆区周围重要建(构)筑物的安全。

The blasting demolition of the old reinforced concrete floodgate of Quangang which was in a very complicated environment was of some difficulty. The work of site experiment which aimed at demolishing the old floodgate of Quangang is introduced in the paper. After modified and checked with the site conditions, the result of the experiment was applied well during production blasting and the safety of the important structures around the blasting area was ensured.
