| titleOfInvention | A kind of impacting with high pressure whitewashing rig for applying to collapse hole stratum and construction method |
| abstract | The invention belongs to the pile foundation construction technical field in foundation engineering, and in particular to a kind of impacting with high pressure whitewashing rig for applying to collapse hole stratum and construction method.The problem of present invention is in order to solve easy collapse hole when cast-in-situ bored pile runs into the stratum such as artesian water and sandy gravel, and then there is provided a kind of impacting with high pressure whitewashing rig for applying to collapse hole stratum and construction method, use and first reinforce on easy collapse hole stratum, the section construction mode of punching again, the advance reinforcing to collapse hole layer surrounding soil is realized using refractory gunning equipment, jump bit impact holing is reused after reinforcing, the intensity of back-up coat can reach 0.1 ~ 8MPa, efficiently solve during drilling construction because artesian water is larger or the stratum such as sandy gravel easily causes collapse hole the problem of, which is not by drilling depth, the limitation of geological conditions etc., can continuously it construct, avoid in construction construction delay caused by collapse hole, construction period has been effectively ensured, with compared with pounding casing or increasing by the way of mud balance, construction cost is lower. |
