[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0014] like Figs. 1 to 3 As shown, a novel simulated sampler includes a core tube 1 and a steel sleeve 2 sleeved outside the core tube 1. The length of the core tube 1 is greater than that of the steel sleeve 2, with a difference of 50 cm. A sealing cap 3 is installed on the top of the core tube 1, and a bottom sealing 4 is provided at the bottom of the steel sleeve 2. A through groove 5 with a width of 15 mm is opened on the side. Several connectors 6 are fixedly fixed at equal intervals inside the through groove 5. The thickness of the connectors 6 is 5 mm.
[0015] like Fig. 3 As shown, the operation steps of the simulated sampler are as follows:
[0016] S1, bury the simulated sampler in the fluidized soil slurry, fix the steel sleeve 2, and insert the core sampling tube 1 into the steel sleeve 2, as follows. Fig. 3 a;
[0017] S2, Rotate the core tube 1 to determine the hardening strength of the fluidized solidified soil based on the resistance, such as Fig. 3 a;
[0018] S3, if the soil initially indicates self-supporting properties, immediately cover the core tube 1 with the sealing cap 3. Removing the core tube 1 allows for further visual assessment of the fluid soil strength. Fig. 3 b;
[0019] S4, after cleaning the soil sample from the core tube 1, insert it back into the steel sleeve 2, and repeat steps S2 and S3, as follows. Fig. 3 b, 3c;
[0020] S5, once there is no more fluidized solidified soil inside steel sleeve 2, it can be determined that the self-supporting capacity of the fluidized solidified soil meets the requirements and will not enter the lock-joint pipe box. Fig. 3 d.
[0021] This simulation sampler can simulate the working conditions of the lock tube in the fluidized solidified soil, and can also sample the fluidized solidified soil. It can also intuitively judge the degree of solidification of the fluidized solidified soil and whether it has the self-supporting property of solidified soil, thereby determining the pull-out time of the lock tube.
