<P>Road foundation is the foundation of road quality, whether it is filling the embankment, or digging the road slot, if the soil treatment is not good, the road construction quality is simply not to mention, for this point is often only theoretical understanding, and in fact Often overlooked, common problems some trench backfill (soil replacement). We are in the process of road construction, often encountered some of the trench backfill construction,<a href="http://maintenancemachineprice.com//road-maintenance-machinery/pothole-repair-products-in-epirus.html">pothole repair products in epirus</a> in the backfill complex soil, often not required, will leave a serious risk to the road quality. Such as the water inside the trough is not clean and back to fill the soil, so that the tank backfill soil water content to be confused will be back to the old oil circuit, concrete and other large pieces of old materials into the groove, resulting in large The gap is great.</P>
<P>Although some of the trench foundation soil, but not by compaction or tamping treatment failed to backfill, etc., the consequences of these reasons are: many roads soon after the completion of the trench parts in the driving under the subsidence occurred, Of the longitudinal cracks and groove parts of the obvious phenomenon of the groove to solve these problems is not difficult, the first is the leadership attention,<a href="http://maintenancemachineprice.com//road-maintenance-machinery/road-blower-manufacturer.html">road blower manufacturer</a> the construction staff (from the construction staff to the team workers) strict checks, not allowed to take water and soil, asphalt Are not allowed to fill the trench, the conditional area should be carried out to shake sand method.</P>
<P>Another layer of solidified, this must be maintained, whether dry clay or other materials, must be pragmatic, the current manual compaction has been rarely used, and no other measures, most of the old materials will fill the surface of the soil after filling the surface Vibration roller rolling, as if it is the only way This method makes the road surface dense very good, it is not true, because even with the use of vibration roller is also limited by the real depth,<a href="http://maintenancemachineprice.com//crack-repair/asphalt-pavement-slotting-machine-tools.html">asphalt pavement slotting machine tools</a> and some are subject to the width of the constraints, No, should be deep in the deep trough is still tampered with the tampon, it is best not to use, we should use lightweight and convenient mechanical compaction tool to solve the trench filling compaction problem.</P> |
