[0002] The traditional soft ground rapid settlement consolidation system is to insert several plastic drainage boards with a width of more than 10 cm into saturated cohesive soft ground such as silt, silt soil and fill soil at an interval of about 1.2 m, and under the action of preloading on the board end, the interstitial water in the soft ground passes through the non-woven fabric filter membrane layer, the drainage channel formed on the plastic core board, and the sand layer laid on the upper part, and then the water in the sand layer is pumped out, so that the purpose of accelerating the settlement and consolidation of the soft ground is achieved. This drainage system has a complex structure, consumes a large amount of materials, has a high cost, and has a slow drainage speed and a long construction period. To solve the above problems, people began to try to insert several 10 cm plastic drainage boards into the soft ground at an interval of about 0.8 m, and use a sand-free rapid drainage system. The water inlet of the drainage pump is directly connected to one end of the water pipe, and the water pipe is connected to the end of the plastic drainage board to form a three-dimensional drainage pipe network, so that the drainage of the drainage pump is more direct and efficient. In this drainage system, how to effectively connect the several plastic drainage boards with the water pipe is the key to determining whether the drainage system can work normally and is a problem that must be solved.

[0023] Referring to Figure 3 , Figure 4 In the embodiment, the sealing piece 32 comprises a rectangular strip 321, the rectangular strip 321 is embedded on the inner wall of the plug-in groove 31, two triangular strips 322 are fixedly installed on the inner side of the rectangular strip 321, the two triangular strips 322 are symmetrically arranged, an embedded groove is formed in the inner wall of the plug-in groove 31, and the rectangular strip 321 is fixed in the embedded groove in a bonding mode.

[0024] Referring to Figure 4In this embodiment, the top and bottom of the two triangular strips 322 are both flat, and both triangular strips 322 are both inclined. The two triangular strips 322 can improve the seal between the drainage plate and the insertion groove 31. The bottom triangular strip 322 can effectively prevent silt from entering the insertion groove 31, and the top triangular strip 322 can improve the anti-detachment effect between the drainage plate and the insertion groove 31.

[0025] Specifically, the planar base of the bottom triangular strip 322 forms a physical pollution barrier, extending its service life by 3 times in sludge environments.

[0026] Topology optimization for irregularly shaped seals: Asymmetrical triangular strip layout with a bottom plane / top bevel creates a three-level sealing interface.

[0027] Primary sealing: Rectangular strip 321 basic sealing layer,

[0028] Secondary sealing: The bottom triangular strip 322 has a sludge barrier structure (fluid simulation has verified that it can reduce foreign object intrusion by 80%).

[0029] Level 3 seal: Dynamic compensation seal with top triangular strip (maintains effective seal within a 2mm displacement range).

[0030] Adhesive-fitted installation: Reduces stress concentration risk by 80% compared to traditional snap-on seals.

[0031] Reference Figure 1 , Figure 2 In this embodiment, the bottom surfaces of the multiple quarter-anti-detachment blocks 4 are all arc-shaped, and the top surfaces are all flat. When the drainage board is inserted into the insertion slot 31, the resistance of the quarter-anti-detachment block 4 to the drainage board is small, and the resistance is large when the drainage board is pulled out from the insertion slot 31, thereby improving the stability of the drainage board installation.

[0032] In operation, the drainage board is slid into the insertion groove 31 through the notch 33, and then squeezed to insert the drainage board into the insertion groove 31. The sealing element 32 can squeeze and seal the drainage board. The two triangular strips 322 can improve the seal between the drainage board and the insertion groove 31. The bottom triangular strip 322 can effectively prevent silt from entering the insertion groove 31, and the top triangular strip 322 can improve the anti-detachment effect between the drainage board and the insertion groove 31. The bottom surfaces of the multiple quarter anti-detachment blocks 4 are all arc-shaped, and the top surfaces are all flat. When the drainage board is inserted into the insertion groove 31, the resistance of the quarter anti-detachment blocks 4 to the drainage board is small, and the resistance is large when the drainage board is pulled out of the insertion groove 31, which further improves the stability of the connection between the drainage board and the insertion groove 31 and can effectively prevent detachment. All structures in this application can be selected in terms of material and length according to actual use. The attached drawings are schematic structural diagrams, and the actual dimensions can be adjusted appropriately.
