某电站左岸溢洪道单孔灌浆效果分析

Analysis on Grouting Effect of Single Borehole for the Left Spillway of a Power Station

摘要:

某电站左岸溢洪道为优化灌浆设计方案，需要对左岸溢洪道布置钻孔进行综合勘察，并在此基础上按照灌浆设计要求进行单孔灌浆试验。为确保施工质量，事先对工艺流程进行优化，同时精选了设备和人员，并严格按照灌浆规范以及符合设计要求的情况下，通过在溢洪道启闭机闸墩、溢洪道二侧、溢流堰等具有代表性的部位进行单孔灌浆试验，取得了良好的灌浆效果，为完善灌浆设计方案提供了依据。

Abstract:

To optimize grouting design scheme of the left spillway for a power station, comprehensive survey was made for borehole arrangement and single borehole grouting tests were demanded. In order to ensure construction quality, the process flow was optimized, the equipment and personnel were strictly selected and single borehole grouting tests were made at representative regions according to the grouting specifications and design requirements, such as gate hoist, 2 sides of spillway and overflow weir with good grouting effects, which could be the basis for sound grouting design scheme.
