[0006] As an improvement of the present invention, when the bottom elevations of the building structures on both sides of the expansion joint are the same, the fixing plates on both sides of the upper part of the drainage trough plate are horizontal and are bolted to the bottom surfaces of the building structures on both sides, and the eagle's beak part of the eagle's beak drip line is installed on the bottom surface of the building structure on that side through a horizontal mounting plate.

[0007] As another improvement of the present invention, when the bottom elevations of the building structures on both sides of the expansion joint are different, the fixed plate on one side of the upper part of the drainage trough plate is horizontal and bolted to the bottom surface of the building structure on one side, the fixed plate on the other side is vertically attached to the side wall of the building structure on the other side and inserted into the socket piece along the line, the socket piece is fixed to the side wall of the building structure on the other side, the eagle's beak part of the eagle's beak drip line on one side is installed on the bottom surface of the building structure on one side through a horizontal mounting plate, and the eagle's beak part of the eagle's beak drip line on the other side is attached to the side wall of the building structure on the other side through a vertical mounting plate and inserted into the slot of the fixed plate on the other side of the upper part of the drainage trough plate.

[0008] Preferably, the cover plate is L-shaped, with one side being horizontally fixed to the top surface of the building structure on one side, and the other side being vertically fixed to the side wall of the building structure on the other side.

[0009] Furthermore, the drainage trough plate is extended by splicing multiple sections, including an end section, a socket section and a middle section. One end of the end section is provided with an end sealing plate and a guide pipe, and the other end protrudes forward through the drainage channel to form a plug. The two ends of the middle section protrude forward through the drainage channel to form a plug. The two ends of the socket section are provided with slots corresponding to the plugs on the drainage channel. The adjacent sections are spliced ​​by inserting the plugs into the slots and using sealant.

[0010] Preferably, the plug projects forwards by at least 300 mm.

[0011] Preferably, the drainage trough plate is made of PVC.

[0012] Preferably, the length of the eagle's beak drip line tightly bonded to the inner wall of the expansion joint on the side through the flexible self-adhesive coil is not less than 100 mm, and the eagle's beak is not less than 15 mm.

[0013] Preferably, the cover plate is made of galvanized steel plate.

[0014] The beneficial effects of the present invention are:

[0015] The cover plate can prevent a large amount of water from entering the expansion joint during heavy rain, reducing the drainage pressure of the expansion joint. The eagle-beak drip line is used to guide the water in the expansion joint to the drainage channel, and the drainage trough plate is used to collect the water in the expansion joint and discharge it through the diversion pipe. The device is easy and reliable to install, and it can effectively solve the problem of water leakage by drainage instead of blocking. There is no need to fill the joint with asphalt hemp or grouting, which improves construction efficiency and reduces project cost. BRIEF DESCRIPTION OF THE DRAWINGS
