Measurement and testing of geothermal floor before installation
1, the measurement engineer's door-to-door measurement, using the infrared range finder inside the installation measurement toolbox to measure the floor area and the amount of the floor auxiliary materials, to avoid the two shipment caused by the inaccurate measurement data.
2. Test the ground, test the water content first, use the water content meter in the installation measurement toolbox, adjust the equipment to the second gear (cement, concrete), test the water content of the surface and wall, and the ground heat floor requires water content less than 10%. If the ground water content is too high, the floor will be easily swellable, causing the floor to arch, drum, sound and other problems, so if the ground water content exceeds the standard value, dehumidification should be carried out.
3, using the infrared thermometer inside the installation measurement toolbox to check whether the heating system is normal, open the heating system, detect the change of surface temperature, all the normal rear can enter the next step. At the same time, the ground flatness is measured, and the ground is placed on the scale by 2M, and the gap between the ruler and the ground is checked with a thick 3mm gauge. The pass is not passed, and the pass is unqualified. If the ground is uneven, it needs to be leveled with a shovel. If the situation is serious, it should be leveled or self leveled.
