Method for preventing ground of square from subsiding
The invention provides a method for preventing the ground of a square from subsiding. The method includes the following steps that firstly, the site is flattened before construction of the site of the square, surface humic matter is removed, the site is pre-pressed one to three times through a land leveler, and the positions of hammering points on the flattened site are marked; secondly, the hammering points are hammered three times, and hammering pits are filled with stones replacing low-strength and high-compression soil to be hammered compactly; and finally, a leveling layer 15-30 cm thick is laid with the mixture composed of 3-8 wt% of cement, 12-18 wt% of coal ash, 70-80 wt% of gravels and 0.2-0.6 wt% of Welan gum. The method for preventing the ground of the square from subsiding is wide in application range. The reinforced foundation is high in strength and good in stability. The quality is easy to control. Construction is convenient and rapid. The method is short in construction period, saves materials and can be widely used for foundation reinforcement of urban construction engineering.
