Description

Technical Field

[0001] The invention relates to the technical field of U-shaped abutments, in particular to a U-shaped abutment with a drainage structure. Background Art

[0002] Gravity abutments, also known as solid abutments, serve as both a load-bearing structure that directly supports the superstructure of the bridge and a combination that closely connects the bridge and the embankment. The load-bearing characteristic is that it relies on its own weight to balance external forces. Gravity abutments are often constructed on-site, and the abutments are mostly constructed of masonry materials such as stone and rubble concrete. Among various types of abutments, gravity abutments are widely used due to their wide range of building materials, simple construction technology and equipment, and easy-to-master construction methods. However, the masonry volume of gravity abutments is large, and the large deadweight requires sufficient foundation strength. They need to be used in areas with good geological conditions at the bridge site. Gravity abutments are divided into various forms according to the bridge span, abutment height, and terrain conditions. The more commonly used types include U-shaped abutments, embedded abutments, straight-line and eight-shaped abutments. A U-shaped abutment refers to a U-shaped structure consisting of a front wall and two side walls. Its advantages are simple structure, large base bearing surface, and low stress.

[0003] However, when the U-shaped abutment is in use, it is necessary to fill the abutment. Water easily accumulates in the fill between the two side walls of the abutment, which swells after freezing and causes cracks in the side walls.

The water mechanism 2 also includes an annular groove 208, which is opened on the outer wall of the drain pipe 205. The drain pipe 205 is internally rotatably connected to a first spur gear 209, which is in contact with the rotating block 207. One end of the first spur gear 209 is fixedly connected to a connecting shaft 210, and one end of the connecting shaft 210 is fixedly connected to a second spur gear 211. The second spur gear 211 is located on the inner wall of the annular groove 208.

[0030] In this embodiment: the mounting plate 201 is attached to the inner wall of the abutment 1 so that the mounting groove 203 is aligned with the drainage hole 202. When the drainage pipe 205 is installed, the rotating block 207 is rotated. The rotating block 207 rotates to drive the first spur gear 209 to rotate. The first spur gear 209 rotates to drive the connecting shaft 210 to rotate. The connecting shaft 210 rotates to drive the second spur gear 211 to rotate. The second spur gear 211 rotates to drive the third spur gear 212 to rotate.

One end of the reinforcement frame 306 extends out of the drain pipe 205, and the outer wall of the reinforcement frame 306 is fixedly connected to an elastic sheet 307.

[0033] In this embodiment: when installing the leaking frame 206, the connecting block 301 is inserted into the connecting groove 304 until the rubber block 302 is deformed and enters the groove 305, thereby installing the leaking frame 206, and when installing the drain pipe 205, the reinforcement frame 306 contacts the inner wall of the installation groove 203, and the reinforcement frame 306 is displaced into the reinforcement groove 303, causing the elastic sheet 307 to be squeezed and deformed, and the connecting block 301 is reinforced to prevent the leaking frame 206 from loosening, causing the leaking frame 206 to remain in the abutment 1 and be difficult to remove.

[0034] Please refer to Figure 2-Figure 4 The outer walls of the drain pipe 205 and the water leakage frame 206 match and are both cylindrical, and the outer wall of the drain pipe 205 fits the inner walls of the drain hole 202 and the installation groove 203.

[0035] In this embodiment, the drain pipe 205 is inserted into the drain hole 202 and the mounting groove 203 . After completion, the rotating block 207 is loosened, and the fixing block 213 is displaced into the fixing groove 204 by the elastic force of the fixing spring 214 to fix the drain pipe 205 .

[0036] Please refer to Figure 6-Figure 9 The outer wall of the fixed block 213 fits with the inner wall of the fixed groove 204 , the third spur gear 212 meshes with the second spur gear 211 , and the outer wall of the rotating block 207 is provided with a tooth groove, which meshes with the first spur gear 209 .

[0037] In this embodiment: the rotating block 207 is rotated, the rotating block 207 drives the first spur gear 209 to rotate, the first spur gear 209 drives the connecting shaft 210 to rotate, the connecting shaft 210 drives the second spur gear 211 to rotate, the second spur gear 211 drives the third spur gear 212 to rotate, the third spur gear 212 drives the fixed block 213 to rotate into the annular groove 208, causing compression on the fixed spring 214.

[0038] Please refer to Figure 4-Figure 7 The outer wall of the connecting block 301 fits with the inner wall of the connecting groove 304, the inner wall of the groove 305 matches the outer wall of the rubber block 302, the outer wall of the reinforcement frame 306 fits with the inner wall of the reinforcement groove 303, and the shape of the reinforcement frame 306 is Z-shaped. A semicircular surface is provided at one end of the reinforcement frame 306 extending out of the drain pipe 205.

[0039] In this embodiment: when installing the leaking frame 206, the connecting block 301 is inserted into the connecting groove 304 until the rubber block 302 is deformed and enters the groove 305, thereby installing the leaking frame 206, and when installing the drain pipe 205, the reinforcement frame 306 contacts the inner wall of the installation groove 203, and the reinforcement frame 306 is displaced into the reinforcement groove 303, causing the elastic sheet 307 to be squeezed and deformed, and the connecting block 301 is reinforced to prevent the leaking frame 206 from loosening, causing the leaking frame 206 to remain in the abutment 1 and be difficult to remove.

[0040] Working principle: fit the mounting plate 201 to the inner wall of the abutment 1 so that the mounting groove 203 is aligned with the drainage hole 202. When installing the drainage pipe 205, rotate the rotating block 207. The rotating block 207 drives the first spur gear 209 to rotate. The first spur gear 209 drives the connecting shaft 210 to rotate. The connecting shaft 210 drives the second spur gear 211 to rotate. The second spur gear 211 drives the third spur gear 212 to rotate. The third spur gear 212 drives the fixed block 213 to rotate into the annular groove 208, squeezing the fixing spring 214. After completion, insert the drainage pipe 205 into the drainage hole 202 and the mounting groove 203. After completion, loosen the rotating block 207. The fixing block 213 is displaced into the fixing groove 204 by the elastic force of the fixing spring 214 to fix the drainage pipe 205.

[0041] The water in the soil in the abutment 1 seeps into the water leakage frame 206 and is then discharged through the drainage pipe 205. The water leakage frame 206 is used to prevent the soil from clogging one end of the drainage pipe 205 and causing blockage of the drainage pipe 205.

[0042] When installing the leaking frame 206, the connecting block 301 is inserted into the connecting groove 304 until the rubber block 302 is deformed and enters the groove 305, thereby installing the leaking frame 206. When installing the drain pipe 205, the reinforcement frame 306 contacts the inner wall of the installation groove 203, and the reinforcement frame 306 moves into the reinforcement groove 303, causing the elastic sheet 307 to be squeezed and deformed, thereby reinforcing the connecting block 301, preventing the leaking frame 206 from loosening, causing the leaking frame 206 to remain in the abutment 1 and be difficult to remove;

[0043] It is convenient to clean and maintain the drainage pipe 205 after dismantling, and before dismantling the drainage pipe 205, the leakage frame 206 is automatically reinforced to prevent the leakage frame 206 from loosening, causing the leakage frame 206 to remain in the abutment 1 and be difficult to remove, thereby facilitating drainage operations on the abutment 1.
