浅议可调支架及丁字尺快速提供基准的研究与应用

The Research and Application of Benchmarking by Adjustable Support and the T-Square

市政及桥梁工程的面层施工在无法封闭施工的条件下,传统的用钢丝提供基准的方法已无法适应市政工程的需要。可调支架支撑6 m铝合金直尺提供基准的方法很好地解决了用传统方法提供基准存在缺点的问题;用丁字尺在没有变坡的两点间提供标高,减少了用普通水准仪进行加密高程点时的计算速度慢的问题。这两种方法在实际工程中的推广和成功应用,加快了施工进度,减少了工程中的浪费,适应了国家环保和绿色施工的要求,提高了工程质量和经济及社会效益。

Under the condition of unable to close the construction,the traditional method of using steel wire to provide reference has been unable to meet the needs of municipal engineering,the adjustable support six meters aluminum alloy ruler to provide reference method well solved the shortcomings of using traditional method to provide reference;to use T-square provides elevation between two points without a slope could reduce the problem of slow computational speed when using normal level. The popularization and successful application of these two methods in practical projects have accelerated the construction progress,reduced the waste in project,adapted to the requirements of national environmental protection and green construction,and improved the project quality and economic and social benefits.
