The surface of the waterproof coating is uneven, or the thickness of the plate is not uniform, and the surface is not flat. After the concrete curing liquid is poured, the surface is only smashed with iron shovel, and the surface is not flattened with trowel, which causes the surface to be rough; the template is not supported on the hard soil layer, or the supporting surface is insufficient, or the support is loose and soaked, resulting in new watering When the concrete curing fluid does not reach a certain level of strength during the early curing; when the concrete curing fluid does not reach a certain strength, the upper man operates or transports the material, causing the surface to appear uneven or printed on the surface in strict accordance with the construction specifications. After the interface agent is used to fill the concrete curing liquid, The screed should be leveled and calendered according to the horizontal control mark or the elastic wire. The waterproof coating should be watered and cured after the final setting; the formwork should have sufficient strength, rigidity and stability, and should be supported on a solid foundation with sufficient support area. Open to prevent water immersion, so as to ensure that no sinking occurs; when pouring concrete curing liquid, strengthen the inspection, the concrete strength reaches 1.2N/mm2 or more, and then walk on the poured structure.
The concrete curing liquid at the corners of the structure or component is partially dropped, irregular, and the cornered wood template is not fully watered or wet enough. The waterproof coating liquid is not well maintained after pouring, causing dehydration, low strength, or swelling of the template. The corners are cracked. When the mold is removed, the edges and corners are glued off; the low-temperature construction removes the side non-load-bearing formwork too early; when the mold is removed, the corners are impacted by external forces or heavy objects, or the protection is not good, the edges are knocked off; the template is uncoated Brush the release agent, or paint unevenly. The wooden formwork should be fully wet before pouring the waterproof coating. After the concrete curing liquid is poured, it should be carefully watered and cured. When the non-load-bearing formwork is removed, the concrete curing liquid should have a strength of 1.2N/mm2 or more. When removing the mold, pay attention to protect the edges and corners and avoid the force. Too rushed; lift the template to prevent impact and corners. When transporting, protect the finished corner with a straw bag to avoid damage. The loose particles can be cut off at the place. After the rinsing is fully wetted, the degree of damage is treated with 1:2 or 1:2.5 cement mortar, or the mold is better than the original concrete curing liquid. Conservation. There is a horizontal or vertical loose mixed soil interlayer in the concrete curing fluid.
