混凝土道路路面平整度以前按常规办法控制,即用竹桩、混凝土小方块作混凝土地面及路面的控制点。实际施工中,竹桩和混凝土块往往被施工人员、运输斗车碰动,而且在捣制混凝土路面时又很难看清竹桩和混凝土块的标高,而失去了控制路面平整度的作用,打出来的路面和地面高低不平,达不到设计要求。最近,我单位旋工了广西桂林横圹英山柴油机厂的厂区混凝土 The road surface smoothness of concrete roads was previously controlled according to conventional methods, ie, bamboo piles and small concrete blocks were used as control points for concrete floors and road surfaces. In actual construction, bamboo piles and concrete blocks are often touched by construction workers and transport bucket trucks, and it is difficult to see the elevations of bamboo piles and concrete blocks when concrete pavements are made, and they lose the effect of controlling the smoothness of the road surface. The road surface and ground that came out were uneven and could not meet the design requirements. Recently, my company has been working on the concrete of the plant of Yingshan Diesel Engine Factory in Guilin, Guilin, Guangxi.
