How to reinforce foundation subsidence
Thread Content
As we all know, the heavy rain in the south caused the slope of our company to collapse. Now we are temporarily laying raincloths for drainage. How will the sunken part be dealt with in the future? Can it be backfilled and drained? It feels like the buildings on the ground have slipped a little.

Reply 1# ovmys Regarding the sliding phenomenon of above-ground buildings, it is necessary to find out whether the bearing capacity of the foundation changes and whether the foundation soil sinks due to slope sliding. If such a phenomenon occurs, foundation reinforcement will be required. There are many ways to strengthen the foundation, which are selected according to the specific situation, such as: Grouting method, ground hole filling quicklime method (lower price), etc. In order to prevent the slope from collapsing again, in addition to backfilling and drainage measures, the slope should be treated. Trees and grass can be planted on the slope, and geotextiles can be added underground.
How to fill holes in the ground with quicklime? This method is very new and fresh. Add quicklime and react with water to form calcium carbonate? Will the pressure increase? How much can be increased?
Agree with the suggestion on the second floor, and a retaining wall can also be added!!
The on-site test showed that the building did not slip much. Digging holes and filling them with quicklime is similar to the principle of hole piles. Do you need to add beam boards on top?
As for the original poster’s question, it’s safer to install reinforced concrete piles!
Concrete pile? The building above is a raw material warehouse with thousands of tons of inventory. It cannot be moved. Even if it could be moved, there would be no place to store it. Where should the piles be driven?
Concrete piles can be driven on the outside of the building!
Both piles and retaining walls must be placed on the outside of the building.
Reply 9# weiyongf It is understandable to add a retaining wall on the periphery, but since the landslide earth and rocks have reached outside the red line, adding a retaining wall requires coordination with local farmers, and the excavator cannot come in. It is expensive! ! ! time! ! ! Is there a better solution? If it is filled with quicklime, are there any such regulations?
Reply 8# weiyf1951 If a pile foundation is added, the pile foundation will bear force from the side, will it have no effect? Yesterday, I saw that the primary school classroom was reinforced to improve its earthquake resistance level, and piles were driven around the perimeter. This should reduce the amplitude of vibrations on higher floors! Following
