水泥砼路面板真空灌浆技术的应用
水泥混凝土路面在我国已有多年的使用历史,是我国公路路面主要形式之一，在我国公路网构成中占有较大比重。它具有强度高、刚度大、受温度影响小、,对超载较为敏感，易发生脱空、唧泥、裂缝等先期病害,从而导致路面的破损。如何治理与预防脱空、唧泥等病害,搞好水泥混凝土路面的养护，延长公路的使用寿命，改善其通行能力,具有十分重要的意义。
Cement concrete pavement in our country has many years of history， is one of the main forms of the highway pavement in our country, in our country have a large proportion in highway network. It has the advantages of high strength, high rigidity， little affected by temperature， long service life etc.. But the cement concrete pavement is more, more sensitive to the overload， prone to separation, mud， cracks early disease， leading to road damage. How to control and prevent separation， pumping diseases， improve the conservation of cement concrete pavement， prolong the service life of the road， to improve its capacity, has a very important ，请勿用作商业用途本文为互联网收集，请勿用作商业用途
随着近年来我国现有的水泥混凝土路面有相当一部分已接近或超过设计年限,水泥混凝土路面最严重的病害路面板的断板直至破碎,而这种情况往往是由于板下脱空所引起的。对此板下灌浆技术是很有效的解决办法，它通过对水泥混凝土路面板下灌注水泥浆液、水泥粉煤灰浆液、水泥砂浆，充实板底脱空空隙,达到稳定水泥混凝土板块的目的,改善路面通车状况的方法.
In recent years， our country existing cement concrete pavement have quite one part has been close to or exceed the design life， broken until the crushing plate slab of the most serious diseases of cement concrete pavement， and this situation is often caused by void beneath slab. This board grouting technology is a very effective solution, which based on the cement concrete pavement cement slurry, cement and fly ash slurry, cement mortar, enrich the slab void void， stable cement concrete plate, to improve the pavement condition。
