传统路基设备有何局限性?
网址:http://www.dhfjx.cn    发布时间:2019-03-22
我国的高速公路路基施工周期短,传统振动压路机压实效果偏小,不均匀沉降成为常见的现象,导致了路面施工质量就算再好,也难以抵御重荷载的碾压。这种因路基不实造成的早期损坏成为中国高速公路建设急需解决的难题。那么传统路基压实设备的局限性都有哪些呢?
The construction period of Expressway Subgrade in China is short, the compaction effect of traditional vibratory roller is small, and the uneven settlement becomes a common phenomenon, which leads to the pavement construction quality even if it is good, it is difficult to resist the rolling of heavy load. This kind of early damage caused by improper subgrade has become an urgent problem to be solved in China's Expressway construction. So what are the limitations of traditional roadbed compaction equipment?
1、冲击式压路机采用牵引车拖动,以一定的速度运动才能产生冲击压实力,无法适应小区间逐段落施工的要求。
1. Impulse roller is driven by tractor, which can produce impact strength only when it moves at a certain speed. It can not meet the requirements of section-by-section construction in different districts.
2、塔吊式强夯,效率极低,灵活性差,均匀性差,转场困,费时费工。
2. Tower-crane dynamic compaction is of low efficiency, poor flexibility, poor uniformity, difficult transfer and time-consuming.

3、打击型夯锤效率低,会对路基造成裂缝,仅适用于桥头局部小面积压实、补强。
3. The impact rammer is inefficient and can cause cracks in subgrade. It is only suitable for local compaction and reinforcement of small area at bridge head.
4、小吨位振动压路机无法满足大粒径填料和大厚度压实的要求,压实质量难以保证,效率低。
4. Small-tonnage vibratory roller can not meet the requirements of large-size filler and large-thickness compaction, compaction quality is difficult to guarantee, and efficiency is low.
