1) Do a good job in flood control and drainage (water interception) system according to the landform. Use the permanent or temporary drainage system of the construction site to eliminate the water flow or water accumulation in the depression.

2) Pay special attention to the choice of fillers in rainy season, and choose soil with appropriate water content. If the soil is too wet, it should be dried before use.

3) When excavating earthwork in rainy days, a certain drainage slope should be maintained on the soil surface and the operation area, so that the construction can be carried out after the rain stops. If the groundwater level in the quarry is high, vertical and horizontal drains should be dug to drain water and reduce the groundwater level.

4) Soil foundation shall be filled with earthwork excavation, and shall not be fully spread. Should be dug, filled, paved, compacted, and make full use of rainwater to stop gap construction.

5) Fill the soil by layers, and the surface of each layer shall have a cross slope of 1.0%- 1.5%, and it shall be leveled. Before it rains or calls it a day, the paved loose soil should be rolled (rammed) and covered in time, and it is too late to roll (rammed).

2, the rainy season stone blasting, appropriate as far as possible to make horizontal hole, in order to avoid explosives, detonators be affected with damp squib.
