早在19世纪中期,水泥混凝土就已经被人们所使用,然而在今天,由于水泥混凝土具有刚度大、稳定性高等特点被广泛应用在了土木工程建设中。随着社会的不断发展,各个工程项目为了能够在市场中得到竞争优势,不断对工程增加各种荷载力,这就促使混凝土的质量才重大压力之下得不到保证,特别是在公路方面,长期以来,由于汽车的数量及通行量对于公路的碾压,从而导致了公路表面存在一些缺陷和问题,最严重的也就是路面板断板或者破碎。通过分析,我们了解到其主要是由于路面板的下部结构脱空而导致的问题。本文就公路施工中真空灌浆技术的应用进行了浅要分析。
As early as the mid-19th century, cement concrete has been used by people, but today, cement concrete is widely used in civil engineering because of its rigidity, high stability and so on. With the continuous development of society, all engineering projects in order to be able to gain competitive advantage in the market, continue to add a variety of load capacity of the project, which promulgated the quality of the concrete under heavy pressure can not be guaranteed, especially in the road, For a long time, due to the quantity and traffic of cars, the rolling of roads has led to some defects and problems on the road surface, the most serious of which is the broken or broken pavement slab. Through analysis, we understand that it is mainly caused by the problem of emptying of the substructure of pavement slabs. This paper analyzes the application of vacuum grouting technology in highway construction.
