[0027] As Figures 1-2As shown, this embodiment discloses an anti-encroachment system for a high-speed railway U-shaped platform wall, including a foundation pit, platform canopy columns 3, U-shaped platform inner wall 2, U-shaped platform outer wall 1, turnbuckle nut 8, first threaded tie rod 5, second threaded tie rod 4, first pull ring 7, and second pull ring 6. The foundation pit is located on the soil beside the train track, and a concrete cushion layer 11 is poured at the bottom of the foundation pit. At the bottom of the foundation pit, from the inside out, the platform canopy column 3, the U-shaped platform inner wall 2, and the U-shaped platform outer wall 1 are poured in sequence. The first pull ring 7 is embedded on the outside of the platform canopy column 3, and the second pull ring 6 is embedded on the inside of the U-shaped platform outer wall 1. In order to improve the firmness, sealing plates are welded to the tail ends of the first pull ring 7 and the second pull ring 6 respectively. The two sealing plates are located on the outer side of the platform canopy column 3 and the U-shaped platform outer wall 1 respectively. In this embodiment, the thickness of the first pull ring 7 and the second pull ring 6 is 15mm, and the size of the sealing plate is 250mm×250mm×15mm.

[0028] like Figure 3 As shown, both the ends of the first threaded tie rod 5 and the second threaded tie rod 4 are welded with elbows. The elbow of the first threaded tie rod 5 is connected to the first pull ring 7. The tail end of the first threaded tie rod 5 passes through the inner wall 2 of the U-shaped platform and extends into the gap between the inner wall 2 and the outer wall 1 of the U-shaped platform. A positioning tube 12 that penetrates the wall horizontally is pre-embedded in the inner wall 2 of the U-shaped platform. A rotatable internal threaded sleeve 13 is installed in the positioning tube 12. The rod body of the first threaded tie rod 5 is threadedly connected to the internal threaded sleeve 13. In order to limit the internal threaded sleeve 13, the two ends of the internal threaded sleeve are respectively welded with pads 9 on the inner and outer sides of the inner wall 2 of the U-shaped platform. The size of the pads 9 is 250mm×250mm×15mm. Two screws that facilitate the rotation of the pads 9 are welded on the pad surface of the pad 9 on the side near the turnbuckle nut 8. The diameter of the screws is 30mm and the length is 50mm. With this design, the screw can rotate the pad, thereby driving the internal threaded sleeve 13 to rotate and tighten the first threaded pull rod 5.

[0029] The elbow of the second threaded tie rod 4 is hooked into the second pull ring 6. One end of the turnbuckle nut 8 is threaded to the tail end of the first threaded tie rod 5 and the other end is threaded to the tail end of the second threaded railing. A soil layer is backfilled between the inner wall 2 of the U-shaped platform and the platform canopy column 3. A concrete cover plate 10 is installed on the top of the U-shaped platform wall.

[0030] The specific construction method of the high-speed railway U-shaped platform wall anti-intrusion system described in this embodiment includes the following steps:

[0031] S1: Prefabricate the first threaded tie rod 5, the second threaded tie rod 4, the first pull ring 7, the second pull ring 6, the turnbuckle nut 8, the positioning tube 12, and the internal threaded sleeve 13 with a washer. The positioning tube 12 is fitted onto the outer wall of the internal threaded sleeve 13.

[0032] S2: Construct the foundation and set the concrete cushion 11 in the foundation pit of the backfill foundation, the thickness of the cushion is 100mm;

[0033] S3: Embed the first pull ring 7 into the platform canopy column 3 when constructing the platform canopy column 3;

[0034] S4: Screw the inner threaded sleeve with the washer 9 into the rod of the first threaded pull rod 5 and connect the elbow of the inner threaded sleeve to the first pull ring 7, according to the distance between the U-shaped platform inner wall 2 and the platform canopy column 3, adjust the inner threaded sleeve 13 to the appropriate position;

[0035] S5: Pour the U-shaped platform outer wall 1 and the U-shaped platform inner wall 2 according to the requirements of the drawing set or relevant specifications, and embed the inner threaded sleeve with the positioning tube and the second pull ring 6 in the U-shaped platform inner wall 2 and the U-shaped platform outer wall 1 respectively;

[0036] S6: Adjust the washer 9 by rotating to make the first threaded pull rod 5 in a just-tight state;

[0037] S7: Pass the elbow of the second threaded pull rod 4 through the second pull ring 6;

[0038] S8: Connect the second threaded pull rod 4 and the first threaded pull rod 5 with the basket nut 8, and adjust the basket nut 8 to make the second threaded pull rod 4 in a just-tight state;

[0039] S9, backfill the soil layer between the U-shaped platform inner wall and the platform canopy column, and assemble the concrete cover plate at the top of the foundation pit.

[0040] During the use of the platform, the device provides a lateral tension to the platform wall to prevent it from tilting and deforming towards the track side. If there is an intrusion problem, the following steps can be taken to adjust:

[0041] a: Open the concrete cover plate 10;

[0042] b: Tighten the washer 9 with the inner threaded sleeve, causing the first threaded pull rod 5 to move the U-shaped platform inner wall 2 towards the platform canopy column;

[0043] c: Tighten the basket nut 8, causing the second threaded pull rod to move the U-shaped platform outer wall 1 towards the platform canopy column;

[0044] d: Confirm that the gauge size meets the requirements and cover the concrete cover plate 10.
