短线法施工控制技术在水工项目中的应用

Application of control technology for short-line construction in maritime works

文章介绍了将桥梁中的短线匹配法施工控制技术应用于梳式滑道井字梁的线形控制中。针对采用短线预制拼装的滑道井字梁在制造及安装阶段的几何误差控制问题,对可能产生的累计偏差采取有效措施进行消除。工程实践表明,该控制技术与施工措施有效保证了井字梁钢轨安装精度和水下安装整体线形。

We present that the control technology for the short-line method in the construction of bridges is applied in thelinear control of the construction of comb-type slipways. To control the geometric error in fabricating and assembling of the＂pound -sign＂ beams for a slipway with the short -line method, we took effective measures to eliminate any potentialaccumulated error. The engineering practice proved that the control technology and construction measures have effectivelyguaranteed the installation accuracy and underwater integral linearity of the steel rails for the slipway.
