桥墩挖井基础大体积混凝土施工技术

Large mass concrete construction technology of pier digging well foundation

为了避免混凝土产生大量水化热造成桥墩挖井基础开裂影响工程质量,从原材料选用、配合比设计、混凝土浇筑及养护等方面采取了有效的控制措施,从而保证大体积混凝土施工质量和工程的预期效益。

In order to avoid the concrete large hydration heat resulting the pier digging well foundation crack and influencing project quality, the author adopts effective control measures from aspects of raw material selection, mixing ratio design, concrete grouting and maintenance, thus ensuring large mass concrete construction quality and project prediction benefit.
