Abstract

The invention relates to a shallow poor subsoil composite foundation stabilization treatment method, which comprises: firstly, digging a hole with a diameter of 100 to 130 millimeters and a depth of 4 to 15 meters, and keeping an inter-pile distance between 800 an 1,000 millimeters; secondly, inserting an earthwork pipe bag, which has a diameter of 150 to 180 millimeters, the same length as the hole and a sealed bottom end, into the hole; preparing a lime-clay mixed filler; filling the mixed filler to the bottom of the earthwork pipe bag, ramming the filler layer by layer to a limited density; and curing the filler in the air naturally, forming shallow bagged and compacted lime piles with a small diameter with the mixed material, laying a 400 to 600 millimeter coarse soil cushion layer on the ground surface of the stabilized area, and rolling the cushion layer with a small mill till the cushion layer is dense. The method can effectively reduce engineering cost, simplify construction working procedures and meet construction requirements.
