不密实 meaning in Chinese
leakiness
◇不密实焊缝 leaky seam
Examples
- Detecting concrete lacuna and holes by ultrasonic
超声波检测混凝土不密实区和空洞 - Considering the gap between steel lining and concrete lining as the imperfect contact , contact layer is proposed to simulate the gap in the combined work analysis
针对这种不密实接触问题，采用厚壁圆环组合环法，提出了在钢衬和混凝土之间设置接触层的钢衬、混凝土衬圈和围岩三者联合受力分析方法。 - In recent years , during the detection of the established reinforced concrete or the prestressed concrete box girder bridges etc . the large structures , we can find that the concrete in particular structural positions such as the anchorage zones of prestressed reinforcement with dense reinforcement , the prestressed pipe in which the space of reinforcement or the thickness of concrete cover is small , the top and bottom flange of box girder and so on has brought great difficulty to concrete construction because of the small size and densely - packed reinforcement
对于变截面t梁、工字梁、箱梁等常见结构,截面形式复杂,一些部位尺寸较小且密集配筋,如梁顶板,梁底板,预应力管道间,混凝土不可避免的造成不密实导致耐久性降低,而这些问题往往为设计者所忽略。对于新建桥梁混凝土的密实度问题,尤其是新建桥梁关键部位的混凝土密实度和耐久性问题,人们研究和关心的较少,这也为桥梁的质量监督控制和使用寿命埋下了隐患。
