Concave Type Concrete Drains Molds For Roadside

Plastic concrete drain molds for roadside using PP polypropylene material made by injection molding,The mainly designed of concave type structure with 3 drain holes,The concrete drain cover plate finished by arc concave design,More easy to ditch drainage.

When we in process of the precast  concrete drains and grates,Use the concrete molds need to noted:

1.Before pouring need to check the plastic concrete drain and grate mold itself was damaged or deformation,If not checked in place will be a direct result of concrete precast finished products become defective,Affect the construction progress and quality.

2.Before the injection of concrete mixture need to remember to apply a high efficiency release agent to facilitate the next construction.

3.After pouring the concrete mixture,You can use the vibration platform for concrete mixture in the concrete drains and grates molds inside the complete elimination of excess bubbles,Improve the quality of concrete products.

4.After the demoulding of concrete drains and grates,Need to do a foreign matter residue cleaning for concrete drains and grates molds,If wait until the concrete impurities dry completely,Then go to cleaning,It will be easy to damage internal structure of the plastic concrete molds,Also easy to cause the finished surface of cement components is roughness and cracks.
