In the construction of the concrete laser leveling machine, the experience and matters of attention are explored. We hope that the construction units have some reference, our country has a vast territory, and the situation in different places is different.
此文先容的混凝土激光整平机机组是为了宣贯《公路混凝土施工技术规范》( JTGF 30— 2003)的标准,使我国混凝土激光整平机水泥混凝土路面施工的总体质量再上新台阶。
Concrete laser leveling machine unit is presented in this paper is for publicizing the "highway concrete construction technology standard" (JTGF 30 - 2003) standards, the overall quality of China's concrete laser leveling machine for cement concrete pavement construction to a new level.
The planeness of the top surface of the template of the concrete laser leveling machine is measured by 3M aluminum alloy ruler. The deviation should not be greater than 2mm. The template joint should be smooth and smooth. Concrete laser leveling machine must not have gaps, wrong platform, warp edge and other defects, the joint is uneven to be corrected, re selected or grinding with a grinding wheel.
Concrete formwork supporting solid laser leveling machine, with the drill rod into the base fixed minimum compression with channel bottom material (such as good quality wood etc.) to adjust the elevation of concrete laser leveling machine should not be placed directly on the above template soft sand material.
Concrete laser leveling machine template is installed, if the local uneven or template bottom gap by bottom concrete block and sit. So be careful in construction.
