[0004] When the workers use the cap beam structure of this self-compacting concrete bridge to provide fixed support for the bridge, the movable beam and the movable block are only fixed by inserting steel bars, and the cap beam is movable through the movable beam, which makes it flexible. In addition, the cap beam itself does not have a mechanism for stable compressive support. When the cap beam is supporting the bridge, it is easy for the cap beam to move slightly when there are frequent vehicles passing by during peak hours, which causes vibration and pressure on the cap beam, thereby affecting the support of the cap beam and causing the support of the cap beam to deteriorate.

[0023] Reference Figure 1-4Furthermore, the grouting reinforcement mechanism is composed of a grouting groove 107, a casting groove 2, a grouting groove 3, a slide 301, a grouting frame 302, a grouting groove 303 and a steel cage 4. Grouting grooves 107 are embedded on both sides of the bridge 106. There are several grouting grooves 107, and every two are equidistantly arranged in parallel. The ends of the fixed columns 102 are arranged inside the opposite grouting grooves 107. The fixed columns 102 are embedded with grouting grooves 3. The steel cage 4 is slidably arranged above the grouting grooves 3, and the steel cage 4 is arc-shaped below. The grouting groove 3 is arranged in a shape, and the upper and lower parts of both sides of the grouting groove 3 are embedded with a slide groove 301, and there are several slide grooves 301, and every two are arranged in parallel at a relatively equidistant manner. A slurry guide frame 302 is relatively slidably arranged on the side of the slide groove 301, and the side of the slurry guide frame 302 is arranged in a semicircular shape. A slurry guide groove 303 is embedded on the side of the slurry guide frame 302. Both sides of the inner wall of the installation groove 105 and the grouting groove 107 are embedded with a casting groove 2, and there are several casting grooves 2, and every two are arranged in parallel at a relatively equidistant manner. When the staff needs to construct a highway bridge, The dry cap 1 is driven into the ground at the designated position through the pile foundation 101. After the cap 1 and the upper fixed column 102 are fixed, the staff drives the crane to lift the prefabricated cap beam 104 to the top of one pair of fixed columns 102, and slides the cap beam 104 through the installation groove 105 to the top of the end of the fixed column 102 for installation. The staff then installs the other cap beams 104 in the same way, and sets up a construction concrete bridge between the cap beams 104. After the top of the end of the fixed column 102 is in the grouting groove 107, the staff After the steel cage 4 is slid into the grouting groove 3, contacts and squeezes the slurry guide frame 302 to slide into the corresponding casting groove 2 on the inner side of the slide groove 301, the staff pours concrete slurry into the grouting groove 3, and allows the concrete slurry to pass through the slurry guide groove 303 of the slurry guide frame 302 and be introduced into the casting groove 2. After waiting for the concrete slurry to dry, the contact area of ​​the fixed column 102 will be increased, and the cap beam 104, the fixed column 102 and the bridge 106 will be firmly connected, thereby improving the effect of the cap beam 104 in firmly supporting the bridge 106.

[0024] Reference Figure 2 , 4 Furthermore, the filling reinforcement mechanism is composed of a reinforcement groove 201. The reinforcement grooves 201 are relatively embedded in the upper and lower inner walls of the casting groove 2. There are several reinforcement grooves 201, and every two are arranged in parallel in an arc shape with equal distances. When the staff pours concrete slurry into the grouting groove 3, the concrete slurry is introduced into the casting groove 2 through the slurry guide groove 303 of the slurry guide frame 302. At the same time, the concrete slurry will be introduced into the several reinforcement grooves 201 above and below the casting groove 2. After the concrete slurry is dried in the arc-shaped reinforcement groove 201, the fixed column 102 will be more firmly connected with the cap beam 104 and the bridge 106, so that the cap beam 104 can provide a more stable support treatment effect on the bridge 106.

[0025] Reference Figure 1 , 2 4. Further, the compression support mechanism is composed of a compression frame A103, a compression frame B5 and a compression frame C501. The compression frame A103 is fixedly installed between the sides of the fixed columns 102, and the compression frame A103 is arranged in an arch shape, and the upper part of the compression frame A103 and the lower part of the cap beam 104 are in contact with each other. The compression frames B5 are fixedly installed on both sides and the middle of the upper part of the cap beam 104, and the compression frame B5 is arranged in a wave shape. The compression frames C501 are fixedly installed between the concave surface of the compression frame B5 and the inner wall of the cap beam 104. There are several compression frames C501, which are arranged in parallel in a triangular column shape with equal distances. When the staff completes the construction of the concrete poured bridge 106 between several cap beams 104, When the bridge is open to traffic for a long time, a large number of vehicles will travel on the top of the bridge 106, which will generate pressure on several cap beams 104. At this time, the wavy pressure-resistant frame B5 on the upper part of the cap beam 104 can disperse the pressure to the surrounding area to avoid the pressure being concentrated on one point and causing great pressure damage to the cap beam 104, which will cause safety hazards. At the same time, several triangular columnar pressure-resistant frames C501 have high strength and stability, and can stabilize the pressure dispersed by the pressure-resistant frame B5. The arched pressure-resistant frame A103 can disperse and resist the pressure again, so that several cap beams 104 can provide more stable support and pressure resistance for the bridge 106, thereby improving the effect of the cap beam 104 in stably supporting the bridge 106.

[0026] Embodiment 2:

[0027] like Figure 4 , 5 As shown, in addition to the embodiment in which a compression frame C501 is fixedly installed between the concave surface of the compression frame B5 and the inner wall of the cap beam 104, and there are several compression frames C501, which are arranged equidistantly in parallel in a triangular column shape, there is another embodiment in which a compression frame C501 is fixedly installed between the concave surface of the compression frame B5 and the inner wall of the cap beam 104, and there are several compression frames C501, which are arranged equidistantly in parallel in an arch shape. When a large number of vehicles travel over the bridge 106, pressure will be generated on several cap beams 104. At this time The wavy compression frame B5 on the upper part of the cap beam 104 can disperse the pressure to the surroundings to avoid the pressure concentration at one point causing great pressure damage to the cap beam 104 and posing a safety hazard. At the same time, several arch-shaped compression frames C501 can disperse the pressure to the surroundings for high-strength compression resistance treatment, and the pressure dispersed by the compression frame B5 is dispersed again and compression-resistant. The pressure is further dispersed and compression-resistant through the arch-shaped compression frame A103. Compared with the first embodiment, the compression support effect is better.

[0028] Working principle: First, when the staff needs to construct a highway bridge, they will drive several caps 1 into the ground at the designated position through pile foundations 101. After fixing the caps 1 and the upper fixed columns 102, the staff will drive a crane to lift the prefabricated cap beam 104 to the top of one pair of fixed columns 102, and slide the cap beam 104 through the installation groove 105 to install it above the ends of the fixed columns 102. Then, the staff will install other cap beams 104 in the same way, and set up construction concrete between the cap beams 104. After pouring the bridge, so that the ends of the fixed columns 102 are above the grouting groove 107, the staff will slide the steel cage 4 into the grouting groove 3, contact and squeeze the grouting frame 302 to slide into the corresponding casting groove 2 on the inner side of the slide groove 301, and the staff will pour concrete slurry into the grouting groove 3, so that the concrete slurry passes through the grouting groove 303 of the grouting frame 302 and is introduced into the casting groove 2. Then, the concrete slurry will be introduced into several upper and lower parts of the casting groove 2 In the reinforcement groove 201, after the concrete slurry is dried inside the arc-shaped reinforcement groove 201, the contact area of ​​the fixed column 102 will be increased, and the cap beam 104, the fixed column 102 and the bridge 106 will be firmly connected. Finally, the concrete-cast bridge 106 is completed between several cap beams 104. When it is opened to traffic for a long time, a large number of vehicles will generate pressure on several cap beams 104 when they are driving on the bridge 106. At this time, the wavy compression frame B5 above the cap beam 104 can disperse the pressure to the surrounding area to avoid the pressure concentration on one point causing greater pressure damage to the cap beam 104 and generating safety hazards. At the same time, several triangular column-shaped compression frames C501 have high strength and stability, and can stably resist the pressure dispersed by the compression frame B5, and disperse and resist the pressure again through the arch-shaped compression frame A103, so that several cap beams 104 can provide more stable support and compression resistance for the bridge 106.
