[0047] Step 4: Under the action of the adapting spring 29, the three push-up brackets 9 are adapted to be inserted into one side of the support frame 5 through the plug-in block 31 to push and support the support frame 5.

[0048] Step 5: Then, start the pressure box 27 to send high-pressure gas into the piston groove of the pusher 9, so that the three pushers 9 can push the support frame 5 stably, and when pushing the steel sheet pile 10, make the sealing strip 12 and the abutment strip 13 of the two adjacent steel sheet piles 10 come into close contact to complete the rapid sealing process.

[0049] Step 6: After the control components on both sides are completed, similarly, the second guardrail 2 of the second layer 4 is set on one side of the bottom of the first layer 3, and the soil is excavated and the support components are used to support it. The two isolation layers are constructed in sections so that the arrangement shape of the top layer and the bottom layer is Z-shaped.

[0050] Step 7: Install a water-stop steel plate and unloading structure between the top and bottom layers. The water-stop steel plate and unloading structure are constructed simultaneously with the bottom slab of the top layer. Finally, backfill the trench and remove the two isolation layers. At this point, the horizontal structural sections of the first layer 3 and the second layer 4 are connected. Example 2:

[0051] Based on Embodiment 1, a piston groove is provided in the center of one side of the pusher frame 9, which is inserted into the pusher tube 8.

[0055] In use, an isolation layer is set at a designated location using the first guardrail 1. The soil inside the isolation layer is vertically excavated to form the first drop layer 3. Then, the support frame 5 is supported and positioned by the placement slots 16 of the four armhole columns 6, and it contacts the first guardrail 1. Then, the servo motor 20 rotates, driving the rotating seat 19 on one side to rotate. Subsequently, under the action of the second synchronous gear 23 driving the synchronous column 17 to move, the synchronous column 17 moves horizontally, and the rotating seat 19 on the other side rotates synchronously. This causes the three push-up frames 9 to be adapted to the side of the support frame 5 by the insertion block 31 under the action of the adaptation spring 29, thus providing push-up support for the support frame 5. Then, the pressure box 27 is activated to send high-pressure gas into the piston groove of the push-up frame 9, so that... Three jacking frames 9 provide stable jacking to the support frame 5, and when jacking the sheet piles 10, ensure that the sealing strips 12 and abutment strips 13 of two adjacent sheet piles 10 are in close contact to complete a rapid sealing process. After the control components on both sides are completed, similarly, the second guardrail 2 of the second layer 4 is set on one side of the bottom of the first layer 3, and the soil is excavated and the support components are used to support it. The two isolation layers are constructed in sections, so that the arrangement shape of the top layer and the bottom layer is Z-shaped. A water-stop steel plate and an unloading structure are set between the top layer and the bottom layer, and the water-stop steel plate and the unloading structure are constructed simultaneously with the bottom plate of the top layer. Finally, the trench is backfilled, and the two isolation layers are removed. At this time, the horizontal structural sections of the first layer 3 and the second layer 4 are connected.
