soccer grass paving the preparatory work before

soccer grass paving the preparatory work before
        ① soccer grass pavers should be checked before template location, elevation, branch and grass-roots level set solid wetting templates inside coat degreasing agent, cement siding coated with asphalt concrete and steel erection and dowel bar, rod and other settings circumstances, qualified before paving.
        ② Channel and set the security fence, picket and so on.
        Two soccer grass paving construction points
        ① paving the maximum thickness of more than once, you should paving and tap twice, but two layers of plaster once paved the interval must not exceed 30min. Should be slightly larger than the thickness of the upper lower that the total thickness of the lower layer thickness is preferably 35.
        ② paving thickness should consider tap the top left height. This height should be concrete pavement testing to determine the initial pilot phase, generally about 10%.
        ③ spade paving, the application of anti-buttoned spade shovel law prohibits throwing and columbine rake.
        ④ Each warehouse concrete paving, vibration, leveling, surface should be done continuously without interruption. Such interruptions should be set construction joints, and design requirements should be established in joint position.
        4 vibrators leveling construction points
        A good paving concrete mixture shall forthwith insert plate vibrator peace evenly tap. The product eliminates the need for concrete plastic tablet tap processes.
        2 Insert the vibrator frequency should be greater than 6000 min.
        3 plate vibrator effective role of depth is generally 18-25cm. Tap should be used 2 ~ 2kW flat vibrator (available when using the vacuum suction technology power smaller plate vibrator). Zhenping available 1 ~ 1kW of plate vibrator.
        4 vibrators vibrators should be inserted in the template to use (or concrete siding) edges, corners or the whole area of ​​early Zhen Zhen once the order early. Vibration should not be less than the same location 20s. Insert vibrator moving distance not greater than the radius of action of 1 to 5 times, its distance from the template is not to be greater than the radius of action of 0 to 5 times, and avoid collisions and steel templates. Then, and then plate vibrator fully vibrators board and the board should overlap between l0 ~ 20cm. The same position vibrated time when water-cement ratio should be less than 0.45 less than 30s, when the water-cement ratio should not be less than 0.45 15s, with no bubbles emerge and prevail glow cement mortar. If conditions then a small power plate vibrator best overall vibration level again.
