Detailed implementation manners

[0020] Embodiment 1

[0021] As Figures 1-3 shown, a bridge water seepage detection device proposed in this embodiment includes a transparent outer cylinder 1, a transparent inner cylinder 2, and an annular piston 14.

[0022] The transparent outer cylinder 1 is arranged outside the transparent inner cylinder 2, and sealing rings a 81 and b 82 are respectively installed at the bottoms of the transparent outer cylinder 1 and the transparent inner cylinder 2; a water inlet pipe 13 is communicated with the transparent inner cylinder 2; scales are provided on the transparent inner cylinder 2, and through the provided scales, operators can easily observe the water level change inside the transparent inner cylinder 2.

[0023] A fixing ring 15 and a connecting ring 16 are arranged inside the annular cavity. The fixing ring 15 is fixed on the inner wall of the transparent outer cylinder 1, and the connecting ring 16 is fixed on the outer wall of the transparent inner cylinder 2. A guide rod a 17 is vertically connected to the fixing ring 15. The guide rod a 17 movably penetrates through the connecting ring 16, and a spring a 18 is sleeved on the guide rod a 17. Under the elastic force of the spring a 18, the sealing ring b 82 at the bottom end of the transparent inner cylinder 2 always tightly abuts against the ground, improving the sealing performance between the sealing ring b 82 and the ground.

[0024] A piston plate 9 is movably arranged inside the transparent inner cylinder 2. A sealing ring c 10 is arranged on the outer periphery of the piston plate 9. A piston rod 11 penetrating through the upper end of the transparent inner cylinder 2 is connected to the piston plate 9, and a pressing plate 12 is connected to the outer end of the piston rod 11. By driving the piston plate 9 to move downward, the water pressure in the transparent inner cylinder 2 can be increased. If there are cracks in the bridge, the more obvious the water level drops through the pressurization test, which is convenient for observation.

[0025] The annular piston 14 is movably arranged in the annular cavity between the transparent outer cylinder 1 and the transparent inner cylinder 2. The annular cavity is filled with sealing mastic. A movable ring 7 is slidably arranged on the transparent inner cylinder 2. A connecting rod 19 passing through the upper end of the transparent outer cylinder 1 is connected between the movable ring 7 and the annular piston 14.

[0026] The bridge seepage detection device further includes a driving assembly. The driving assembly includes a chassis 3, a lifting frame 4 and a linear driving mechanism 5. The lifting frame 4 is fixedly connected to the transparent outer cylinder 1. The chassis 3 is arranged below the lifting frame 4. A plurality of universal wheels are installed at the bottom end of the chassis 3. The linear driving mechanism 5 is installed on the chassis 3 and its output shaft is connected to the lifting frame 4. By setting the linear driving mechanism 5, the lifting frame 4 is driven to move downward, so that the sealing ring a81 can tightly abut against the ground to prevent the sealing mastic from overflowing.

[0027] Before the test, the device is moved to the position to be detected. The movable ring 7 is pushed downward to drive the sealing mastic in the annular cavity to move to the bottom end to fill the tiny gap between the sealing ring b82 and the ground. Then, water is poured into the interior of the transparent inner cylinder 2 through the water inlet pipe 13. By observing the change of the water level and the bottom end of the bridge, it is determined whether there is a seepage phenomenon in the bridge.

[0028] Embodiment 2

[0029] As Figure 1 and Figure 4 shown, a bridge seepage detection device proposed in this embodiment, compared with Embodiment 1, further includes a transparent support 6 in this embodiment. The transparent support 6 is arranged at the bottom end of the transparent outer cylinder 1. A circular hole 601 for the transparent outer cylinder 1 to pass through is opened on the transparent support 6. Two semi-circular rings 20 are symmetrically arranged in the annular cavity. Activity grooves a101 for the semi-circular rings 20 to pass through are opened on both sides of the transparent outer cylinder 1. Activity grooves b602 for the two semi-circular rings 20 on both sides to pass through are opened on the transparent support 6. Two installation grooves 603 are opened at both ends of the transparent support 6. Guide rods b25 are arranged on the inner sides of the installation grooves 603. Slide plates 22 are slidably arranged on the guide rods b25. Springs b26 are sleeved and installed on the guide rods b25. Connecting plates 21 are connected between the slide plates 22 and the corresponding semi-circular rings 20. Connecting frames 23 are arranged at both ends of the transparent support 6. Both ends of the connecting frames 23 are respectively connected to the two slide plates 22 on the corresponding side. Slide holes 604 are opened at both ends of the transparent support 6. Push rods 24 are slidably installed in the slide holes 604 on both sides. Wedge blocks are arranged at the upper ends of the push rods 24.

[0030] In this embodiment, after the transparent support 6 is placed on the ground, the push rod 24 first contacts the ground and forces it to move upward. The push rod 24 drives the wedge block to move upward, and the wedge block pushes the connecting frame 23 to move outward. The connecting frame 23 drives the semi-circular ring 20 to move, separating the two semi-circular rings 20, so that the sealant in the annular cavity can be smoothly discharged. After the detection is completed, when the device is lifted, the semi-circular ring 20 is driven to reset under the elastic force of the spring b26, so that the two semi-circular rings 20 both move to the inner side of the annular cavity, thereby realizing the sealing of the inner side of the annular cavity and preventing the sealant from solidifying. The sealant at the bottom of the semi-circular ring 20 can be manually scraped off by the operator.

[0031] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge of those skilled in the art without departing from the purpose of the present invention.
