[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of the embodiments of the present invention.

[0026] Reference Figure 1 The present invention provides a device for preventing slurry intrusion in cable-stayed bridge cable saddles. The device comprises a set of cable saddles 1 and anchor pads 2 welded to each end of the cable saddles. Each cable saddle is provided with an inner lining tube 4. The inner lining tube is installed inside the cable saddles. The inner lining tube is 20 cm longer than the outer saddle tube and has an outer saddle length of 10 cm on each side. The number of inner lining tubes is arranged according to the specifications of the cable saddles.

[0027] The end of the branching tube is sealed with foam glue 5, which is polyurethane foam glue, mainly used to seal the inner branching tube opening. After the sealing is completed, the periphery of the foam glue is wrapped with transparent tape.

[0028] The foam glue at the end of the filament tube is wrapped with transparent tape.

[0029] The group of wire tubes are arranged compactly and have a regular hexagonal cross section. The wire tubes are welded together from small steel tubes to form a continuous tube. There are four specifications, which are welded together from 43, 61, 73, and 109 steel tubes, with an outer diameter of 28mm, an inner diameter of 22mm, and a wall thickness of 3mm. Each steel strand of the wire tube passes through the corresponding small steel tube, forming a separate arrangement without interfering with each other. The wire tubes penetrate the anchor plate and are flush with the outer edge of the anchor plate. Figure 2 shown.

[0030] The anchor plates are available in four sizes: 550*550*65mm, 550*550*75mm, 600*600*85mm, and 650*650*100mm. The anchor plates are installed on the outside of the tower column, with their outer edges flush with the concrete surface. Bolts (3) are located around the anchor plates for securing them to the anchor boxes. These bolts pass through the anchor plates and are welded to them. The bolt diameter is 20 mm, and the exposed lengths are 12.5 cm, 14.5 cm, 15.5 cm, and 21 cm, respectively.

[0031] An anchor box 6 is installed on the upper surface of the anchor plate. The anchor box includes a bottom plate fixedly connected to the anchor plate and side plates respectively standing on the three sides of the bottom plate. The adjacent sides of the three side plates are connected and fixed. The bottom plate is provided with bolt holes for installing bolts, such as Figure 3As shown in the figure, the anchor box is installed on the anchor plate surface. The anchor box is assembled from bamboo plywood and has Φ22 holes. The number of holes is determined by the number of pre-embedded bolts in the anchor plate. Align the anchor box holes with the bolt positions on the anchor plate and install. After installation, the bolt heads should protrude outside the anchor box. The anchor box is secured with bolts and nuts at the four corners of the anchor plate.

[0032] The utility model provides a construction device for preventing slurry intrusion of a cable-stayed bridge wire pipe saddle. The construction steps are as follows:

[0033] 1. Pre-embed the wire distribution pipe saddle inside the tower column and fix it;

[0034] 2. Install an inner lining tube inside the wire distribution tube;

[0035] 3. Install the anchor box on the anchor pad and fix it;
