高桩码头现浇面层裂缝控制

Crack control on cast-in-place surface of high-pile wharf

高桩码头现浇面层质量控制的关键就是裂缝控制,也是面层施工的难点之一。裂缝的成因比较复杂,结合工程实践,从混凝土配合比设计、结构钢筋布置、施工工艺三大方面,综合分析了裂缝成因并提出有效的控制措施。实际工程效果良好。

The crack control is the key to the quality control of the high-pile wharf cast-in-place surface layers, and it is always the difficulty of the surface layer construction. The causes of the cracks are very complex, by combining with engineering practice, we put forward the fracture causes and the effective control measures from the three aspects: design of concrete mix proportion, arrangement of structural steel, and construction technology. The practical engineering effect is good.
