高强度螺栓紧扣法检查在港珠澳大桥上的应用

Application of High-strength Bolt Tight-fitting Inspection Method in Hong Kong-Zhuhai-Macao Bridge

螺栓质量检查分为松扣-回扣法和紧扣法两种,在标准规范中,关于松扣-回扣法检查描述很详细,但对于紧扣法描述相对简单笼统,没有统一的操作规程和操作步骤,因此,对于使用紧扣法质量检查,应该进行测定紧扣检查扭矩试验,应当规范统一紧扣法施工质量检查。

Bolt quality inspection is divided into two types: loose fitting-rebate method and tight-fitting method. In the standard specification, the description of the loose fitting-rebate method is very detailed, but the description of the tight-fitting method is relatively simple and general, and there is no uniform operation procedure and the operation steps, therefore, for the use of the tight-fitting quality inspection, the tight-checking test should be carried out, and the construction quality inspection should be standardized.
