Description

Technical Field

[0001] The utility model belongs to the technical field of expansion joint waterproof and drainage devices in engineering structures, and particularly relates to a water diversion device for expansion joints in bridge construction. Background Technique

[0002] When the environmental temperature of a bridge changes, the bridge deck will have deformations of elongation or shortening; and under the action of vehicle live loads, the beam ends will also have angular deformations and longitudinal displacements. In order to enable vehicles to pass smoothly through the bridge expansion joint and meet the requirements of structural deformation, an expansion device is installed at the expansion joint. Since there is a water leakage phenomenon at the bridge beam expansion joint, a water diversion device needs to be set at the expansion joint for waterproofing and drainage. After retrieval, the patent with the application number 201320083352.9 discloses a waterproof and drainage device for bridge expansion joints. The bridge bodies on both sides of the expansion joint are connected by an expansion device. Installation grooves are reserved at one ends of the two bridge bodies close to the expansion joint. The waterproof and drainage device is fixed in the expansion joint through the installation grooves on both sides of the expansion joint. The waterproof and drainage device includes a water collection tank assembly and anchor bars arranged on both sides of the water collection tank assembly. Sealing plates for closing the water collection tank assembly and drain pipes connected to the sealing plates are arranged at both ends of the water collection tank assembly.

[0003] However, during the actual use process, the applicant found that when guiding the rainwater flowing to the expansion joint to the G-shaped water collection tanks on both sides through the inverted U-shaped movable diversion plate, a considerable part of the rainwater will flow out from both ends of the inverted U-shaped movable diversion plate, thus unable to effectively achieve waterproofing and drainage at the bridge expansion joint. In view of this, we propose a water diversion device for expansion joints in bridge construction. Content of the Utility Model

[0020] Please refer to Figures 1-3 as shown. The present utility model provides a technical solution:

[0021] A water diversion device for expansion joints in bridge construction, comprising a first bridge body 1 and a second bridge body 3. The first bridge body 1 and the second bridge body 3 are connected by a steel plate expansion device 6. An expansion joint 2 is provided between the first bridge body 1 and the second bridge body 3. Installation grooves 4 are opened on both the first bridge body 1 and the second bridge body 3 on both sides of the expansion joint 2. A U-shaped frame base 7 and anchor bars 8 are fixedly cast in the installation grooves 4 through a concrete casting layer 5. The anchor bars 8 are welded and fixed on the outer side wall of the U-shaped frame base 7. A number of anchor bars 8 on the U-shaped frame base 7 are arranged side by side at equal intervals. The two ends of the steel plate expansion device 6 are respectively fixedly connected to the two concrete casting layers 5. The opening directions of the two U-shaped frame bases 7 are opposite. The two U-shaped frame bases 7 are connected by a water collection frame 9. And the two ends of the water collection frame 9 are respectively movably connected to the two U-shaped frame bases 7. A guide rail 71 is fixedly arranged at the bottom inside the U-shaped frame base 7. A sliding groove 93 at the bottom of the water collection frame 9 is slidably matched with the guide rail 71 on the inner side wall of the U-shaped frame base 7. The two ends of the water collection frame 9 protrude from both sides of the first bridge body 1 and the second bridge body 3, so that the water collection frame 9 can effectively collect the rainwater flowing towards the expansion joint 2. The top of the water collection frame 9 fits with the top inside the U-shaped frame base 7. The opening of the water collection frame 9 faces upward. A water diversion branch pipe 10 is fixedly connected to the lower part of the water collection frame 9 through a water diversion main pipe 11. The water diversion main pipe 11 is connected through a drain pipe outside the connecting pipe. A number of water diversion branch pipes 10 between the water collection frame 9 and the water diversion main pipe 11 are arranged side by side at equal intervals. A drainage groove 91 is opened at the bottom inside the water collection frame 9 above the water diversion branch pipe 10. The setting of the drainage groove 91 enables the rainwater collected inside the water collection frame 9 to be better drained into the water diversion branch pipe 10. Through the water collection frame 9, the rainwater flowing between the expansion joints 2 can be collected, and the rainwater collected inside the water collection frame 9 can be quickly guided into the water diversion main pipe 11 through the water diversion branch pipe 10, and finally drained into the external drain pipe through the water diversion main pipe 11, effectively realizing the water diversion and drainage of the bridge. When diverting and draining water at the expansion joint 2 of the bridge, the rainwater flowing between the expansion joints 2 can be effectively collected through the expansion joint 2, and the rainwater collected inside the water collection frame 9 can be quickly guided into the water diversion main pipe 11 through the water diversion branch pipe 10, and finally the rainwater can be drained into the external drain pipe through the water diversion main pipe 11, realizing the water diversion and drainage of the bridge.

[0022] The bottom of the water collecting frame 9 is symmetrically provided with sliding grooves 93. The U-shaped frame seat 7 and the water collecting frame 9 are elastically connected by springs 12. A first connecting column 72 is fixedly arranged on the inner side wall of the U-shaped frame seat 7 side by side and at equal intervals. On both sides of the water collecting frame 9, second connecting columns 92 are symmetrically arranged side by side and at equal intervals. The second connecting columns 92 on both sides of the water collecting frame 9 respectively correspond to the first connecting columns 72 on the inner walls of the two U-shaped frame seats 7 one by one. Both ends of the spring 12 are respectively sleeved on a group of the first connecting column 72 and the second connecting column 92. By arranging the springs 12, when the width of the expansion joint 2 changes, the opening above the water collecting frame 9 can always stay at the expansion joint 2, so that the rainwater flowing to the expansion joint 2 can be smoothly collected. When the width of the expansion joint 2 changes, at this time, due to the elastic force of the springs 12 on both sides of the water collecting frame 9, the opening above the water collecting frame 9 can always stay at the expansion joint 2, so that the rainwater flowing to the expansion joint 2 can be smoothly collected.

[0023] Working principle: When in use, when draining and guiding water at the bridge expansion joint 2, the rainwater flowing between the expansion joints 2 can be effectively collected through the expansion joint 2, and the rainwater collected inside the water collecting frame 9 can be quickly guided into the water guiding branch pipe 10 and finally drained into the external drain pipe through the water guiding branch pipe 11 to realize the water drainage and guiding of the bridge. When the width of the expansion joint 2 changes, at this time, due to the elastic force of the springs 12 on both sides of the water collecting frame 9, the opening above the water collecting frame 9 can always stay at the expansion joint 2, so that the rainwater flowing to the expansion joint 2 can be smoothly collected.
