真空预压卸载后，厂房建筑物轮廓线范围（边线外扩2 m，20048.4

After vacuum preloading is unloaded, the outline of the plant building (the side line is expanded by 2 m, 20048.4 m2) is backfilled with silty sand or silt to +4.600 m in layers of 50 cm, and the backfill soil is subjected to dynamic compaction and vibration rolling deal with. After the other areas are backfilled to the design elevation, vibration rolling is performed. <br>The dynamic tamping adopts two full tamping treatments, a flat hammer with a ram diameter of 2.0 ~ 2.5 m. Click tamping energy 800 KN · M, 1 hit per point; after full tamping is completed, level the site and perform vibration rolling. The construction parameters of vibration rolling are as follows:

After vacuum pre-pressure unloading, the plant building contour range (edge expansion 2 m, 20048.4 m2) is layered backfilling fine sand or powder edgs of 50 cm to .600 m, and the backfill soil is strongly pressed and vibration crushing processed. Other areas are backfilled to the design elevation for vibration crushing.<br>The strong crucified is treated with 2 times, flat hammer, hammer diameter 2.0 to 2.5 m. Click on the energy 800 KN. M, 1 strike per point; when the full crucified crucified is complete, level the field and vibrate and crush. The construction parameters for vibration crushing are as follows:

After vacuum preloading and unloading, the contour range of the power house building (2 m outside the sideline, 20048.4 m2) is backfilled to + 4.600 m by 50 cm layers of fine sand or silt, and the backfill is subject to dynamic compaction and vibration rolling. Other areas shall be backfilled to the design elevation for vibration rolling treatment.<br>The dynamic compaction shall be carried out twice with full compaction, flat hammer with a diameter of 2.0-2.5m. Click the ramming energy of 800 kn · m, one blow per point; after full ramming, level the site and conduct vibration rolling. The construction parameters of vibration rolling are as follows:<br>
