[0023] The trash retaining plate 10 is vertically placed between the preset components 40, and the bottom and left and right sides of the trash retaining plate 10 are inserted into the gap, such as Figure 3 and Figure 2 As shown, the trash plate 10 is reinforced so that the trash plate 10 is not easy to deviate and fall over. When the sludge flows toward the trash plate 10, the trash plate 10 will block the flow of the sludge.

[0024] The buffer plate 20 includes a slope section 21 and a positioning section 22 whose extension directions are perpendicular to each other. The positioning section 22 is detachably mounted on the upper end of the trash retaining plate 10. The bottom of the slope section 21 is in close contact with the top of the preset component 40. The top of the slope section 21 has an inclined surface 211. The inclined surface 211 is in the opposite direction to the downhill direction. When the sludge flows toward the trash retaining plate 10, the sludge will flow onto the slope section 21, thereby compacting the buffer plate 20 downwards. The trash retaining plate 10 is further stabilized by the buffer plate 20. At the same time, when the sludge moves toward the trash retaining plate 10, the inclined surface 211 will.

[0025] In addition, the structure further includes:

[0026] The support rod 30 has one end welded to the trash-blocking plate 10 and the other end welded to the sleeper 41 placed on the preset component 40, so as to further improve the stability of the trash-blocking plate 10 and prevent it from falling backwards.

[0027] Based on the above structure, a bending section 221 is provided at the end of the positioning section 22 of the buffer plate 20 away from the slope section 21, so that a recess 2211 is formed on the positioning section 22, and the positioning section 22 is clamped on the trash retaining plate 10 through the recess 2211; a groove matching the bending section 221 is provided on the trash retaining plate 10, so that the bending section 221 is clamped in the groove, which is beneficial to the installation of the buffer plate 20 and can also avoid lateral displacement of the buffer plate 20.

[0028] At the same time, the trash retaining plate 10 is also provided with a fixing screw 11, which extends transversely on the side wall of the trash retaining plate 10. In addition, a fixing groove 2212 matching the fixing screw 11 is opened on the bending section 221, and the fixing screw 11 can be embedded in the fixing groove 2212; a nut 111 is screwed on the fixing screw 11, and the nut 111 is pressed toward the bending section 221 to clamp the bending section 221 and the trash retaining plate 10 through the nut 111, so that the buffer plate 20 is fixed to the trash retaining plate 10. At the same time, when the buffer plate 20 needs to be disassembled, it can be separated by loosening the nut 111 and then disassembled.

[0029] Based on the above structure, the fixed thread groove has an opening extending to the edge of the positioning section 22, so that the fixing screw 11 can extend into the fixed thread groove through the opening; and the extending direction of the opening is vertically downward, such as Figure 5 As shown, during installation, align the opening with the fixing screw 11 and insert it so that the fixing screw 11 is inserted into the fixing groove 2212, and then screw the nut 111 onto the fixing screw 11, and tighten the nut 111 toward the bending section 221 so that the bending section 221 and the dirt retaining plate 10 can be clamped by the nut 111.

[0030] In addition, a positioning protrusion 2213 is provided on the side of the bending section 221 close to the trash retaining plate 10; a positioning groove 12 that matches the positioning protrusion 2213 is opened on the trash retaining plate 10, and when the bending section 221 is embedded in the groove and the positioning protrusion 2213 contacts the trash retaining plate 10, the bending section 221 will be plastically bent outward until the positioning protrusion 2213 corresponds to the positioning groove 12, and the bending section 221 plastically rebounds, so that the positioning protrusion 2213 is embedded in the positioning groove 12 for preliminary positioning, and the cross-section of the positioning protrusion 2213 is arc-shaped, which makes the embedding smoother and less likely to get stuck.

[0031] The embodiment of the utility model further provides a movable trash-blocking plate in a shield tunnel, the trash-blocking plate adopts the trash-blocking plate structure as described above, and the preset component 40 is an inner wall component of the shield tunnel;

[0032] During installation, the spacer trash-blocking plate 10 is first inserted into the gap between the inner wall components of the shield tunnel, and then the buffer plate 20 is installed on the trash-blocking plate 10 in the above manner, and then the sleeper 41 and the track are installed.
