Winter construction, to choose the right plastic drainage plate, with the material of polypropylene as the main ingredient of plastic drainage plate, high hardness, flexibility, strong! Cold winter is for construction for construction industry at a disadvantage when both outdoor and indoor has great influence, for the construction of plastic drainage plate so if temperature is too low in accordance with the requirements is not allowed, but sometimes need to catch up have to construction, then increases the construction difficulty of plastic drainage plate in the process of construction is to be aware of a few. Today we will introduce plastic drainage plate in winter construction matters needing attention.
A, the first is the foundation of treatment are much more complicated than usual, thoroughly cleaning the laying face, do level of matrix, and the entity ramming, cannot have the emergence of concave and convex pit, but also for the fracture of the ground for a snap bridge processing, etc. In a nutshell is to make laid with smooth surface without sundry, mainly because the temperature is lower in winter relatively very brittle plastic drainage plate is easy to break so try to avoid bending.
Second, the second when laying the whole coil to avoid flat broken when we want to advance to preheating of plastic drainage plate, is it on the fire or capacitor preheat the prevent from broken temperature is too low.
Three, the last is at the time of welding in winter low temperature normally only commonly used welding machine for welding, adopt adhesive gummed unstable if there is frost is easy to cause water seepage phenomenon.
