超高压水力破拆混凝土参数分析
|
摘要
超高压水力破拆混凝土方式与传统机械破拆方式相比具有突出优势。以伯努利方程为理论基础对超高压水力破拆混凝土过程进行分析,建立混凝土表面水力与泵压参数间的关系,并在实验的基础上探究超高压水力破拆的各项参数与破拆效果间的关系,对超高压水力破拆混凝土的分析与应用具有一定的参考意义。
The technology of concrete dismantling with ultra-high pressure water has a prominent advantage relative to traditional mechanical operation. The Bernoulli equation was used to analyze the process of ultra-high pressure water breaking concrete. The relationship between pump pressure parameters and ultra-high pressure water of concrete surface was established. On the basis of the experiment, the relationship between the parameters of the ultra-high pressure water concrete dismantling and the effect of dismantling was investigated. The results have a certain reference significance for the analysis and application of ultra-high pressure water concrete dismantling.
