Therefore, it is necessary to reduce the water content of the weak soil and to remove the weeds at the roots before the construction. In the traditional construction process, if the water content of the excavated soil is high, a natural tedding water content method is generally adopted, such as: adopting a soil heap over-wind method in a windy section; airing the soil in situ by adopting a 'ploughing method' in a soil yard, and then excavating according to the ploughing depth; and (3) excavating a 'ventilation groove' in the stock dump to accelerate the water loss of the soil body. According to field practice, the water content of the soil material is reduced by natural tedding, the water content can be reduced by only 3% day and night, and the efficiency is low.
