Abstract

[0002] Soft soil refers to fine-grained soil with high water content, large porosity, high compressibility and low shear strength. In order to treat and reinforce soft soil foundations, plate compactors are often used. Plate compactors exert strong impact energy on soft soil foundations, forming shock waves and dynamic stresses in the foundation soil, which compact and vibrate the soft soil foundation so as to reinforce it. At present, the commonly used methods for soft soil foundation treatment are mainly the following: excavation and replacement method, cushion layer method, riprap method, drainage consolidation method, reinforced soil piles, bagged sand wells, and dynamic compaction method.
[0003] In the prior art, soft soil foundation construction mostly adopts the excavation and replacement method, in which the interior of the foundation pit is filled with more stable and strong reinforced concrete. However, before filling the reinforced concrete, concrete needs to be used independently at the lowest end of the foundation pit to increase its compressive resistance. However, the existing method requires pouring multiple layers of concrete, and the construction period is long. When cracks appear in the concrete at the bottom, there is a high risk of collapse, and it cannot be replaced in time. Moreover, the concrete at the bottom alone cannot guarantee its stability, so a support device with a replaceable base and a support structure is needed. Utility Model Content
