摘要
提出利用测定水泥含量的方法控制水泥搅拌桩施工质量。该检测方法采用新型取土装置取土以及改进EDTA法检测水泥含量,克服了传统强度检测操作复杂、检测结果片面、受水泥土龄期影响等问题。通过杨林船闸工程试验桩检测表明,该方法能有效检测搅拌桩的水泥含量和搅拌均匀性。将水泥含量作为水泥搅拌桩质量评判指标,能够直观反映水泥搅拌桩施工质量,并且检测速度快,成本低,能起到及时控制施工质量的目的。
A method of detecting cement dose in controlling construction quality of cement mixing piles is proposed in this paper. It works with improved EDTA titration to detect cement dose and a new type of device to borrow earth is also necessary. Complex operations, one-sided results and influence by the age of cement soil will be overcome. Cement mixing test piles are detected in Yanglin lock pro- ject . Results show that cement dose and mixing uniformity can be detected effectively with this meth- od. Construction quality of cement mixing piles can be showed directly and its advantages of tection speed, low cost, timely construction quality control are significant when cement dose ded as the quality parameter of cement mixing piles. fast de is regar
