[0035] Refer to Figures 1 to 5, the present utility model provides a waterproof detection device for a bridge expansion device, which is used to detect the waterproof performance of a bridge expansion joint. The bridge expansion joint includes side beams 110, anchor fittings 120, and waterproof rubber strips 130. There are two plate members 200, which are respectively and sealingly arranged on both sides of the top surface of the side beams 110; the waterproof members 300 are arranged at both ends of the plate members 200, and the waterproof members 300, the bridge expansion joint, and the plate members 200 form a containing space.

[0036] In this embodiment, the device seals by arranging the plate members 200 on both sides of the top surface of the side beams 110. The waterproof members 300 are installed at both ends of the plate members 200, and together with the bridge expansion joint and the plate members 200, they form a closed containing space. Through the two plate members 200, the height of the containing space is increased. After adding water to the containing space, the water surface can completely submerge the bridge expansion joint, ensuring the comprehensiveness of the inspection of the bridge expansion joint.

[0037] By arranging the plate members 200 and the waterproof members 300 on the bridge expansion joint, the water for detection can stay in the containing space. The detection process will not cause other impacts on the bridge expansion joint, and it is convenient to set up, greatly improving the detection efficiency and simplicity.

[0038] Furthermore, the plate member 200 is in an L-shaped long strip shape, and it also includes a waterproof double-sided self-adhesive strip 400. One side is adhesively attached to the top surface of the side beam 110, and the other side is adhesively connected to the plate member 200. The plate member 200 is sealingly arranged on the side beam 110 through the waterproof double-sided self-adhesive strip 400.

[0039] In this embodiment, the design of the L-shaped long strip-shaped plate member 200 can not only more closely fit the contour of the top surface of the side beam 110, but also provide a wider sealing contact surface, further improving the reliability and stability of the seal. The introduction of the waterproof double-sided self-adhesive strip 400 greatly simplifies the installation process of the plate member 200 and the side beam 110. One side is adhered to the top surface of the expansion joint side beam 110, and the other side is adhered to the L-shaped plate member 200. Such a design not only ensures an excellent sealing effect, preventing water vapor penetration, but also avoids potential leakage points brought by traditional fixing methods such as bolt connection, improving the continuity and integrity of waterproofing. The use of the self-adhesive strip is also convenient for on-site construction, reducing the dependence on professional installation tools, and reducing the construction difficulty and cost.

[0040] Furthermore, the waterproof member 300 is waterproof sealant.

[0041] In this embodiment, the waterproof sealant not only has a low price, which can reduce the detection cost, but also can be kneaded into the required shape, with strong applicability.

[0042] Further, the plate member 200 includes a main body 210, the main body 210 has a sliding groove 211, and the direction of the sliding groove 211 is the same as the length direction of the side beam 110; the sliding plate 220 is slidably arranged in the sliding groove 211, and after the sliding plate 220 slides, one end of the sliding plate 220 extends out of the sliding groove 211.

[0043] In this embodiment, the main body 210 of the plate member 200 is designed with a sliding groove 211 that is consistent with the length direction of the side beam 110. This design allows the sliding plate 220 to freely slide within the sliding groove 211. Such a structure enables the entire device to be adjusted according to the actual length of the bridge expansion joint, improving the versatility and adaptability of the device, enabling it to be applicable to bridge expansion joints of different length specifications, reducing the customization cost and inventory pressure.

[0044] Further, one end of the main body 210 close to the outlet of the sliding groove 211 further has a threaded hole 212, and further includes a sealing gasket 230, which is arranged at the outlet of the sliding groove 211; the tightening member 240 is rotatably arranged at the threaded hole 212, the tightening member 240 is threadedly connected to the threaded hole 212, and after the tightening member 240 rotates, the tightening member 240 presses the sliding plate 220 against the sealing gasket 230.

[0045] In this embodiment, a threaded hole 212 is provided at one end of the main body 210 for installing the tightening member 240 in a threaded connection manner. This design enables the tightening member 240 to precisely and powerfully apply pressure to the sliding plate 220 by rotating, so that the sliding plate 220 can closely adhere to the sealing gasket 230 to form a sealing interface, effectively preventing moisture and debris from entering the inside of the expansion joint, enhancing the waterproof performance. Ensuring the accuracy of adjustment and the reliability of fastening. This not only simplifies the installation and adjustment process, but also improves the fastening efficiency and durability of the system. The sealing gasket 230 is usually made of materials with good weather resistance and excellent elasticity, such as rubber or silica gel.

[0046] Further, it further includes a fixing platform 250, which is arranged at the threaded hole 212, and the fixing platform 250 has a through hole, and the tightening member 240 passes through the through hole and then enters the threaded hole 212.

[0047] In this embodiment, the fixing platform 250 is arranged at the threaded hole 212, and this fixing platform 250 can provide a stable placement basis for the tightening member 240. After the tightening member 240 is screwed out from the threaded hole 212, the tightening member 240 can remain on the fixing platform 250, facilitating the next tightening and preventing the loss of the tightening member caused by disassembly.

[0048] Further, the bottom of the sliding plate 220 is flush with the bottom of the main body 210.

[0049] In this embodiment, the bottom of the sliding plate 220 is flush with the bottom of the main body 210, ensuring the continuity and flatness of the bottom of the entire device, contributing to the formation of a complete sealing surface and reducing the possibility of water and debris penetrating from the bottom.
