[0020] As another embodiment of the present application, Figure 4 and Figure 6 As shown, the penetration probe 1 of the present application is a hollow structure; a transverse slot 11 is provided at the end of the penetration probe 1, and an elastic ball 24 for plugging into the transverse slot 11 is provided at the upper end of the penetration cone seat 2, so that the penetration probe 1 and the penetration cone seat 2 can be detachably connected. Furthermore, the bottom of the penetration probe 1 is fitted on the upper part of the penetration cone seat 2, and the elastic ball 24 pushed out by the spring is embedded in the transverse slot 11 at the bottom of the penetration probe 1 for installation and combination, so as to prevent the penetration base from falling off under its own weight.

[0021] See also Figure 6 An opening is provided on one vertical side of the penetration probe 1 so that the penetration probe 1 surrounds the flexible sensor chain 5 on three sides, so that it can be separated from the structure after the penetration is completed.

[0022] See also Figure 1 The elastic clamping mechanism 4 includes a reaction blade 41 and an expansion spring 42 . The reaction blade 41 is composed of multiple blades, and the multiple reaction blades 41 are hinged to the cone head 3 along the circumferential direction. One end of the expansion spring 42 is fixedly connected to the reaction blade 41 .

[0023] Specifically, four flippable reaction blades 41 are hinged at the bottom of the penetration cone seat 2 , and four expansion springs 42 are installed at the inner center of the reaction blades 41 .

[0024] See also Figure 4 The present application further comprises a blade sheath 6, which is slidably disposed on the outer wall of the penetration probe 1. In the penetration preparation state, the protrusion on the upper part of the reaction blade 41 is inserted from the bottom of the inner part of the penetration sheath, thereby preventing the reaction blade 41 from being unfolded.

[0025] As another embodiment of the present application, Figure 1 and Figure 5As shown, the penetration cone seat 2 of the present application includes a cone 21 and a connecting rod 22, the connecting rod 22 is fixedly arranged at the lower end of the cone 21, and the connecting rod 22 is connected to the cone head 3; the vertical cross section of the cone 21 is an inverted trapezoidal structure, so that the reaction blade 41 can be received into the inverted trapezoidal structure slope of the cone 21 by penetrating the soil layer. A rectangular table is eccentrically arranged on the cone 21, elastic balls 24 are arranged on two or three sides of the rectangular table, and a mounting hole 25 is arranged on one side of the rectangular table.

[0026] The application process:

[0027] ① Place the flexible sensor chain 5 in the penetration probe 1 and connect it to the penetration cone seat 2;

[0028] ② By clamping the penetration probe 1, the device is vertically penetrated into the soil, and the blade sheath 6 slides upward due to the resistance of the soil, and the reaction blade 41 is in a state where it can be freely expanded;

[0029] ③ When the penetration reaches the specified depth, the penetration is stopped. As the soil resistance in the penetration direction disappears, the reaction blade 41 opens outwards under the action of the spring.

[0030] ④ The penetration probe 1 begins to be recovered. Due to the action of the elastic ball 24, the penetration cone 2 will be driven upward to a certain extent, so that the soil layer contacts the reaction blade 41, providing reverse resistance for the penetration cone 2, so that the reaction blade 41 is deployed.

[0031] ⑤ In the process of pulling the penetration probe 1 upward, due to the expansion of the reaction blade 41, the resistance of the soil layer to the penetration cone seat 2 increases, overcoming the binding force between the elastic ball 24 and the penetration probe 1, so that the penetration probe 1 is separated from the penetration cone seat 2.

[0032] ⑥ The penetration probe rod 1 continues to be pulled out and recovered, and the flexible sensor chain 5 and the penetration cone seat 2 structure remain in the formation, so that the sensor chain 5 can directly contact and couple with the formation.
