Reinforcement Technology of Foundation Pit Engineering on Miscellaneous Fill Soil Rich in Water

A project faces a problem which is water burst and sand boil between the piles on miscellaneous fill soil when digging the soil and settig up anchors after constructing the slop shield piles,and now we need to reinforce its foundation pit on the miscellaneous fill soil.After detailed demonstration,we use the methods of grouting reinforcement and adding anchor.We calculate the two anchoring parameters according to the specification,and do the anchor test,at last we find out the anchor reinforcement design meeting the requirements according to the basic test results.We successfully solve the shutdown problem caused by groundwater influence and ensure the project completed.
