In the prior art, the anti-seepage and support of the soft foundation are mostly constructed in a split type, for example, an anti-seepage plate or an anti-seepage wall is first inserted, and then grouting or supporting pile is used for reinforcement. Such a construction method has the following defects: The anti-seepage and support are constructed in steps, and the secondary operation can cause disturbance to the preliminarily stabilized soft soil layer, easily causing uneven settlement of the stratum and reducing the engineering stability; the collaborative operation of multiple devices needs multiple times of shifting and debugging, the construction period is long, and the cost of manpower and material resources is high; the combination of the traditional support structure and the anti-seepage body is poor, the interface is easy to form a seepage channel, and the support strength is difficult to adapt to the creep characteristics of the soft soil layer.

[0027] The multi-stage transmission device 3 is provided in multiple numbers and arranged on the upper and lower sides of the anti-seepage plate 1. The anti-seepage plate 1 is provided with the multi-stage transmission device 3 on the upper side, the first connecting shaft 301 of the multi-stage transmission device 3 is connected with the inner wall of the upper side of the anti-seepage plate 1, the fixed rotating shaft 309 is rotationally connected with the first support plate 103, and the first connecting shaft 301 is fixedly connected with the third gear 206.

[0028] Specifically, the multi-stage transmission device 3 adopts a multi-stage transmission structure of gears and planetary gears. After the first connecting shaft 301 receives the power of the rotation of the third gear 206 and the fourth gear 207, the first speed increase is realized through the meshing of the fifth gear 302 and the sixth gear 303, and then the planetary driving gear 306 is rotated to drive the planetary inner gear 307 and the planetary outer gear 308 to rotate reversely and synchronously, finally driving the blade assembly 4 to rotate. This structure can significantly improve the cutting torque of the blade and enhance the soft soil reinforcement effect.

[0030] Specifically, the blade assembly 4 adopts a design where the inner and outer toothed blades rotate synchronously in opposite directions. The outer toothed blade 401 is connected to the planetary external gear 308, and the inner toothed blade 402 is connected to the fixed rotating shaft 309. The synchronous rotation in opposite directions is achieved through planetary gear transmission. The serrated blade edges 403 on the blade edges can efficiently cut soft soil.

[0031] Furthermore, the horizontal moving device 5 includes a cam shaft 504 fixedly connected to the eighth gear 311. A cam 503 is mounted on the cam shaft 504, and a side plate 501 is provided on one side of the cam 503. Multiple side support plates 502 are provided on the side plate 501, and the side support plates 502 correspond to the side plate openings 102. Furthermore, the end of the cam shaft 504 away from the eighth gear 311 is rotatably connected to the first support plate 103, and the lower end of the cam shaft 504 passes through the second support plate 104.

Through the meshing of the seventh gear 310 and the eighth gear 311, the power of the multi-stage transmission device 3 is transmitted to the cam shaft 504. The cam shaft 504 drives the cam 503 to rotate, thereby pushing the side plate 501 and the side support plate 502 to extend horizontally and insert into the soft soil layers on both sides of the seepage barrier to form a three-dimensional support system, which effectively resists lateral soil pressure and prevents the seepage barrier from shifting.

[0033] Specific Implementation Two The first support plate 103 and the second support plate 104 are fixed in the preset positions inside the seepage barrier plate 1 to ensure levelness; a blade opening 101 and a side plate opening 102 are opened on the seepage barrier plate 1, and the edges are polished smooth.

[0034] The drive shaft 201, the first gear 202, and the second gear 203 are installed at the center of the seepage barrier 1 to ensure flexible rotation. The first rack 204 and the second rack 205 are respectively installed in the upper and lower edge guide rails of the seepage barrier 1 and mesh with the first gear 202 and the second gear 203. On both sides away from the first gear 202 and the second gear 203, the third gear 206 and the fourth gear 207, which mesh with the first rack 204 and the second rack 205, are installed.

[0035] The two sets of multi-stage transmission devices 3 are installed on the first support plate 103. One end of the first connecting shaft 301 is fixedly connected to the third gear 206 and rotatably connected to the upper inner wall of the seepage-proof plate 1. The other end is connected to the fifth gear 302. The fifth gear 302 meshes with the sixth gear 303. The sixth gear 303 transmits power to the planetary drive gear 306 through the second connecting shaft 304. The planetary drive gear 306 transmits power to the planetary external gear 308 and the planetary internal gear 307 through meshing. The external tooth blade 401 is fixedly connected to the planetary external gear 308. The fixed rotating shaft 309 is fixedly connected to the planetary internal gear 307. The fixed rotating shaft 309 is fixedly connected to the internal tooth blade 402. The rotation of the planetary drive gear 306 drives the planetary external gear 308 and the planetary internal gear 307 to rotate synchronously in opposite directions, which drives the blade to rotate synchronously in opposite directions, so that the blade extends smoothly from the blade opening 101. One end of the fixed rotating shaft 309 is installed on the first support plate 103.

[0036] The next two sets of multi-stage transmission devices 3 are installed on the second support plate 104. One end of the first connecting shaft 301 is fixedly connected to the fourth gear 207 and rotatably connected to the lower inner wall of the seepage-proof plate 1. The other end is connected to the fifth gear 302. The fifth gear 302 meshes with the sixth gear 303. The sixth gear 303 transmits power to the planetary drive gear 306 through the second connecting shaft 304. The planetary drive gear 306 transmits power to the planetary external gear 308 and the planetary internal gear 307 through meshing. The external gear blade 401 is fixedly connected to the planetary external gear 308. A fixed shaft 309 is fixedly connected to the internal gear 307. The fixed shaft 309 is fixedly connected to the internal gear blade 402 and to the seventh gear 310. The seventh gear 310 is located on the upper side of the internal gear blade 402, and the top of the fixed shaft 309 is connected to the second support plate 104. The planetary drive gear 306 rotates to drive the planetary external gear 308 and the planetary internal gear 307 to rotate synchronously in opposite directions, which in turn drives the blades to rotate synchronously in opposite directions, so that the blades can smoothly extend from the blade opening 101. The planetary internal gear 307 drives the seventh gear 310 to rotate through the fixed shaft 309.

[0037] The seventh gear 310 meshes with the eighth gear 311, driving the cam shaft 504 fixedly connected to the eighth gear 311. The cam shaft 504 drives the eccentric cam 503 fixed on the shaft to rotate. The rotation of the eccentric cam 503 pushes the side plate 501 to move, causing the side support plates 502 installed on the side plate 501 to move horizontally. The side support plates 502 installed on both sides of the seepage-proof plate 1 are pushed out and inserted into the soft soil layers on both sides.

[0038] The device is hoisted to the designated construction location, and its verticality is adjusted to ensure that the anti-seepage board 1 is vertically aligned with the construction point. Downward pressure is applied to make the anti-seepage board 1 slowly sink. When it sinks to the design depth, the power source is started to drive the drive shaft 201 to rotate. The power is transmitted to the two sets of multi-stage transmission devices 3 at the top and bottom through the rack and pinion transmission device 2. The multi-stage transmission device 3 drives the blade assembly 4 to rotate. The inner and outer toothed blades rotate in opposite directions and cut into the soft soil synchronously to form a horizontal blade three-dimensional support. At the same time, the power of the multi-stage transmission device 3 is transmitted to the horizontal moving device 5 through the seventh gear 310 and the eighth gear 311, driving the cam 503 to rotate and pushing the side support plate 502 to extend from the side plate opening 102 and insert into the soft soil layers on both sides to form a three-dimensional support on the side.
