In a project,the deep foundation is in the deep silt silt clay layer,and the foundation pit support is provided with two layers of horizontal internal support.Under the foundation waterproof plate,the anti-floating bolt of high-strength fine rolled steel is set according to the 2500 mm spacing.In order to realize the on-site bearing capacity test of high-strength bolt on the soft soil layer under the internal support beam,a combined test device is developed.The fabrication and installation process,site combination and matters needing attention in use are introduced.Through practical application,the new combined test device can meet the test requirements of high-strength bolt bearing capacity in soft soil,effectively solve the site problems such as low space,soft soil and large deformation,and provide reference for the anti-floating bolt pulling test in similar engineering sites.
