For any dynamic compaction project, it is necessary to be familiar with the terrain and soil layer of the construction site, pay more attention to the weather conditions of the project site in wet seasons, and arrange the waterproof measures of the backfill tamping pit site in advance.

在雨天，施工现场的所有强夯机械设备和配电装置都要避免雨水淋湿。强夯施工现场的排水沟和截水沟。为了防止低洼的地方积蓄很多污浊水，要做到强夯施工场地现场的平整性，地面平整就不会有积水。反之，场地地面凹凸不平坑坑洼洼在降雨后就一定有积水，应该立使用污水泵及时的排清，夯坑的积水也采取同样手段处理。假如有淤泥，就得使用挖掘机械挖除干净，接着要把淤泥运离强夯场地之外。

In rainy days, all dynamic compaction mechanical equipment and power distribution devices on the construction site shall be protected from rain. Drainage ditch and intercepting ditch at dynamic compaction construction site. In order to prevent a lot of dirty water from accumulating in low-lying areas, first of all, the flatness of the dynamic compaction construction site should be achieved, and there will be no ponding if the ground is flat. On the contrary, the ground of the site is uneven, and there must be ponding after rainfall. The sewage pump should be used to drain it in time, and the ponding in the tamping pit should also be treated by the same means. If there is silt, you have to use the excavation machinery to dig it out, and then transport the silt away from the dynamic compaction site.

一般来说，地基表面没有积水的情况下主夯才能进行施工。在经过雨水浸润的强夯工程场地，地层处于表面湿度大和水含蓄量非常高的现象，禁止进行满夯施工。对于基坑内部强夯施工处理，为防止地表水透，周围需要做泛水水坡来解决地表水。

Generally speaking, the construction can be carried out only when there is no ponding on the foundation surface. In the dynamic compaction project site infiltrated by rainwater, the stratum is in the phenomenon of high surface humidity and very high water content, and full compaction construction is prohibited. For the dynamic compaction construction treatment inside the foundation pit, in order to prevent surface water from penetrating, a flashing slope needs to be made around to solve the surface water.
