Research on Green Slurry Circulation Construction Technology for Soldier Pile Wall Support of Deep and Large Foundation Pit in Sandy Gravel Stratum
A new type of green slurry circulation construction technology for deep and large foundation pit soldier pile wall support is studied based on the background of a deep and large foundation pit soldier pile wall support construction in Chengdu.The technology is mainly composed of slurry ditch,dewatering well and sedimentation tank in the new slurry circulation system.The slurry ditch forms a circular passage to replace the traditional slurry tank.The engineering practice shows that compared with the traditional slurry ditch,the green slurry circulation system not only reduces the number of slurry tanks,reduces soil consumption and land occupation,but also adopts chemical slurry to solve the problem of slurry leakage and collapse in the drilling process.The slurry of the two sedimentation tanks is purified,which is easier to meet the environmental protection requirements.
