《建筑技术》杂志介绍了美国盒式水准器的构造及使用方法,我结合实际情况进行了改制。经工程使用,效果良好。现将具体做法介绍如下。一、原理盒式或管式水准器都采用连通器原理,或大气压强原理。水平、水平,以水为平。水不平则流,流则不平。盒式、管式都采用了水不流动时的水平面作为工程测量的基线。水准仪也离不开水,水准仪上 The magazine “Architecture Technology” introduced the structure and use of the United States box-level equipment. I combined the actual situation with the restructuring. Used by the project, the effect is good. The specific practices are described below. First, the principle of cartridge or tube level adopts the principle of connected vessels, or atmospheric pressure principle. Level, level, level with water. Water is uneven and flow is uneven. Box and tube type adopt the water level when the water does not flow as the baseline for engineering measurement. The level gauge is also inseparable from the water level.
