Embodiment 1
[0045] see figure 1 , an isolated reinforcement method based on soft soil foundation, including the following steps:
[0046] S1. Excavate a 30cm deep top covering pit on the surface of the area to be reinforced, and then place 1 root / 10m in the top covering pit 2 The density is evenly drilled to set multiple reinforcement pile holes;
[0047] S2. Install the casing to shape the reinforcement pile hole, process the prefabricated pile 1 in the factory in advance, transport it to the site and hoist it into the casing;
[0048] S3. Temporarily locate the prefabricated pile 1, and then take out the casing one by one, and ensure that the hole collapse phenomenon is avoided during the process. After the casing is completely taken out, inject isolation filler into the gap between the prefabricated pile 1 and the reinforced pile hole ;
[0049] S4. After the isolation filler is injected and filled densely, the isolation cladding 2 is formed, the temporary positioning is removed, an...
