Shallow poor subsoil composite foundation stabilization treatment method

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.

AI Technical Summary

Benefits of technology

This new technology allows for efficient utilizing smaller spaces or deeper bases while also being able to effectively treat hardened areas by filling them with special material called Lime Piled Composite (LPC) that forms tiny groups inside it. These LPCS have unique features such as easy handling, quick assembly time, minimal size requirements, less expensive materials compared to traditional methods like cementation, but they still provide important technical benefits when applied at small locations where there may be no suitable base structure available due to environmental concerns associated with excavating operations.

Problems solved by technology

This patented technical problem addressed by this patents relates to improving the durable nature of buried underground structures like those used at building sites due to their vulnerabilities caused by factors like loose ground conditions and lack of load support during use. Conventional ways involve filling them up before they can be put back down again after being placed over time without any significant improvement in terms of supporting loads compared to newfound ones.
