电缆槽因结构设计复杂、断面尺寸小，造成电缆槽的线性和表面气泡等外观质量难以控制，文章针对电缆槽一次成型整体式模架在施工中出现的模板上浮影响线性和拆模后混凝土表面气泡超标的问题，通过对模板受力分析，采取增加结构件及标高预控等措施，有效减少模板上浮高度；通过在模板上增设附着式振动器并不断优化布置方案，测定附着式振动器作用时间，有效减少拆模后混凝土表面气泡含量。

Appearance quality of cutter cable groove, i.e. linearity and surface bubble, is difficult to control due to complex structural design and small crosssection size. Stress analysis of framework, components adding and elevation precontrol are used to reduce the floating height of the framework; adnexed vibrator adding on the framework and its layout optimization and acting time monitoring of the vibrator are used to reduce the bubble on concrete surface.
