[0043] In the above description, when the construction joint to be sealed is large, the support plate 1 can be first placed horizontally in the construction joint, then the support area of the support plate 1 is increased by the expanding mechanism 4 to ensure the stability of the support plate 1 on the inner wall of the construction joint, then the outer wall of the positioning rod 36 on both sides is pulled outward to make the outer wall of the positioning rod 36 disengage from the limiting hole and the positioning hole formed in the outer wall of the support plate 1, so that the clamping of the fixed plate 35 is released, at this time the spring 33 loses the limiting, and then rebounds downward to drive the limiting plate 32 to move downward, which in turn drives the connecting rod 34 to move downward, and the pressing plate 37 moves downward through the downward movement of the connecting rod 34, which in turn drives the rubber strip 38 to move downward through the downward movement of the pressing plate 37, and then the rubber strip 38 is extruded by the cooperation between the pressing plate 39, so that the extruded rubber strip 38 deforms, and then extends outward, and since the rubber strip 38 has a trapezoidal shape with a small upper end and a large lower end, the rubber strip 38 has a large space to extend outward, which increases the external contact range of the rubber strip 38, so that the inner wall of the large construction joint can be contacted and sealed, which can timely seal the construction joint, and the rubber strip 38 that fits the construction joint does not need to be found, thereby improving the construction efficiency.
[0044] Specifically, as shown in Figure 1 , Figure 3 , Figure 4 and Figure 5 , the outer wall of the support plate 1 on both sides is provided with a positioning hole, which is fitted with the outer wall of the positioning rod 36, and the positioning hole can clamp the fixed plate 35, and the two are fitted to effectively ensure the stability of the clamping.
[0045] Specifically, as shown in Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, the connecting rods 34 are two in number and symmetrically arranged on both sides of the top end of the pressing plate 37, so as to support the top end surface of the pressing plate 37 on both sides, thereby ensuring the uniformity of the extrusion of the rubber strip 38.

[0047] In the above description, when it is necessary to expand the area of the support plate 1, first push the extrusion block 45 to move to the left side, at this time the extrusion block 45 moves through the sliding block 44 in the inner wall of the sliding groove 43, so that the extrusion block 45 moves to contact and extrude the outer wall inclined surface of the extension plate 42, and then the extension plate 42 is extruded outward, and then the rotating shaft 41 is rotated to drive the extension plate 42 to rotate outward, so that the overall area of the support plate 1 is increased, thereby adapting to the construction joint larger than itself, ensuring the limiting stability of the support plate 1 in the construction joint before sealing, thereby improving the sealing quality.
[0048] Specifically, as shown in Figure 1 、 Figure 3 and Figure 8 , the number of extension plates 42 is two, and the extension plates 42 are symmetrically arranged on the left and right sides of the support plate 1, so that the area of the support plate 1 can be expanded on both sides, thereby improving the stability of the clamping installation of the support plate 1.
[0049] Specifically, as shown in Figure 1 、 Figure 3 and Figure 8 , the outer wall of the extension plate 42 is provided with a stress inclined surface, and the outer wall of the extrusion block 45 is provided with an extrusion inclined surface, so that the stress inclined surface and the extrusion inclined surface can better bear stress and exert force.
[0050] The implementation principle of the subway construction joint anti-seepage device is as follows:
[0051] When the construction joint to be sealed is large, the support plate 1 can be first placed transversely in the construction joint, then the support area of the support plate 1 is increased by the expansion mechanism 4 to ensure the support stability of the support plate 1 on the inner wall of the construction joint, then the positioning rods 36 on both sides are pulled outward, so that the outer wall of the positioning rods 36 is separated from the limiting holes and the inner walls of the positioning holes on the outer wall of the support plate 1, so that the clamping and limiting of the fixed plate 35 are released, at this time, the spring 33 will lose the limiting, and then rebound downward to drive the limiting plate 32 to move downward, the connecting rod 34 is driven to move downward along with the downward movement of the limiting plate 32, the pressing plate 37 is driven to move downward through the downward movement of the connecting rod 34, the rubber strip 38 is driven to move downward through the downward movement of the pressing plate 37, and then the cooperation between the rubber strip 38 and the pressure plate 39 can generate a squeezing action on the rubber strip 38, the rubber strip 38 subjected to the squeezing action will be deformed, and then extend outward, and since the rubber strip 38 has a trapezoidal shape with a small upper part and a large lower part, the rubber strip 38 will have a large space to extend to the four sides, so that the external contact range of the rubber strip 38 is increased, so that the inner wall of the large construction joint can be contacted and sealed, so that the construction joint can be sealed in time, without the need to find a rubber strip 38 that fits it, thereby improving the construction efficiency and preventing water seepage of the construction joint.
[0052] When it is necessary to expand and increase the area of the support plate 1, the extrusion block 45 is first pushed to move to the left, and the extrusion block 45 moves in the sliding groove 43 through the sliding block 44, so that the outer wall inclined surface of the expansion plate 42 is contacted and extruded by the extrusion block 45, so that the expansion plate 42 subjected to the extrusion can generate an outward force, and then the expansion plate 42 is driven to rotate outward by the rotation of the rotating shaft 41, so that the overall area of the support plate 1 is increased, so that the support plate 1 can be adapted to a construction joint larger than itself, and the limiting stability of the support plate 1 in the construction joint is ensured before sealing, thereby improving the subsequent sealing quality.
[0053] The above is only a preferred embodiment of the present application, and is not intended to limit the protection scope of the present application.
