Description

Technical Field

[0001] The utility model relates to water seepage detection equipment for municipal bridges, belonging to the field of water seepage equipment. Background Art

[0002] As an important part of highway traffic, the safety of concrete bridges is directly related to the safety of people's lives and property. Concrete bridges will be affected by the environment and loads during use, and leakage is one of the common problems. Leakage not only affects the service life of the bridge, but also endangers the safety of the bridge. Therefore, it is necessary to detect the leakage problem of concrete bridges.

[0003] Leakage detection of concrete bridges should be carried out at locations where leakage may occur, such as bridge piers, bridge decks, bridge supports, etc.

[0004] For water seepage detection on bridge decks, a water seepage meter is generally used for detection.

[0005] The Chinese utility model patent with application number CN202321226791.0 provides a water permeability meter for asphalt surface penetration testing.

[0006] Before using the water seepage meter, you need to determine the detection position, then use a metal ring to cover the outside of the detection area, and then apply waterproof material to the outer periphery of the metal ring. Use the waterproof material to fill the gaps in the concrete surface, and then compact and smooth it to prevent water from leaking from the detection area during detection.

[0007] Therefore, before the staff prepares to use the water seepage meter, they need to waterproof the area around the water seepage meter. The applicant believes that waterproofing and testing can be combined into one to save time. Utility Model Content

[0024] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0025] See also Figure 1-3 This is an embodiment of a water seepage detection device for municipal bridges of the utility model.

[0026] It includes a detector and a concentric limit ring 1; the concentric limit ring 1 consists of a small diameter limit ring 2 and a large diameter limit ring 3 arranged concentrically; the detector includes a base plate 4 and a pressure ring 5 arranged at the lower end of the base plate 4, and the pressure ring 5 is placed between the small diameter limit ring 2 and the large diameter limit ring 3.

[0027] The detection method of the present device is different from the detection steps of the prior art;

[0028] In the prior art, when testing, a metal ring is used to encircle the area to be tested, and then the waterproof material is evenly applied to the area outside the metal ring, and then the waterproof material is compacted. At this time, the waterproof material will fill the concave and convex parts of the concrete surface, and then the metal ring is removed and the detector is placed on the area to be tested;

[0029] At this time, the staff can operate the detector to inject water into the area to be tested. The injected water will not overflow due to the surrounding waterproof materials. By observing the rate of water infiltration, the water infiltration efficiency of the concrete bridge pavement can be obtained.

[0030] The detection method of this device is:

[0031] Place the concentric limit ring 1 in the area to be tested, and the area to be tested is located inside the small diameter limit ring 2; then squeeze the waterproof material into the area between the small diameter limit ring 2 and the large diameter limit ring 3, and then align the pressure ring 5 at the lower end of the detector with the area between the small diameter limit ring 2 and the large diameter limit ring 3, and put it directly down, using the weight of the detector itself to compact the waterproof material; then you can operate the detector.

[0032] Compared with the prior art, the present device eliminates the steps of applying waterproof material, manually compacting waterproof material, and removing metal rings; the function of filling the depression on the concrete surface with waterproof material can be completed by directly utilizing the limiting functions of the small-diameter limiting ring 2 and the large-diameter limiting ring 3 and combining the weight of the detector itself; the operation is simpler and more convenient.

[0033] The concentric limiting ring 1 further comprises a connecting rod 6 arranged between the small diameter limiting ring 2 and the large diameter limiting ring 3 , and a bottom groove 7 is arranged on the pressing ring 5 , and the connecting rod 6 corresponds to the bottom groove 7 in upper and lower positions.

[0034] The purpose of setting the connecting rod 6 between the small diameter limiting ring 2 and the large diameter limiting ring 3 in this device is to make the small diameter limiting ring 2 and the large diameter limiting ring 3 become a whole, which is convenient for use; at the same time, due to the setting of the connecting rod 6, a corresponding bottom groove 7 needs to be provided on the pressure ring 5 to avoid interference;

[0035] However, in actual use, such a setting still presents a problem, that is, the waterproof material below the connecting rod 6 will not be pressed by the pressing ring 5; the applicant believes that the detector can be rotated as a whole, and the rotating detector can press on the waterproof material that has not been pressed just now; therefore, it still has strong practicality.

[0036] There are four connecting rods 6 , which are evenly distributed between the small-diameter limiting ring 2 and the large-diameter limiting ring 3 .

[0037] There are four connecting rods 6, which can make the small-diameter limiting ring 2 and the large-diameter limiting ring 3 more stable.

[0038] The bottom plate 4 is disc-shaped, and the diameter of the bottom plate 4 is larger than the outer diameter of the pressure ring 5 .

[0039] The height of the pressure ring 5 of this device is slightly smaller than that of the small-diameter limit ring 2 and the large-diameter limit ring 3 because they need to be filled with waterproof material. The bottom plate 4 is arranged in this way so that when the detector is pressed down, the bottom plate 4 contacts the upper end surfaces of the small-diameter limit ring 2 and the large-diameter limit ring 3, so that a gap is formed between the pressure ring 5 and the ground. The formed gap is the filling space for the waterproof material.

[0040] A water injection groove 8 is arranged on the lower end surface of the bottom plate 4 , and a water injection pipe 9 is arranged in the middle of the bottom plate 4 , and the water injection pipe 9 is connected to the water injection groove 8 .

[0041] The water injection tank 8 is to inject water into it through the water injection pipe 9 after all the above preparations are done. Usually, a valve is provided on the water injection pipe 9, and a measuring cylinder is provided on the valve, so that the rate of water falling can be observed, which is convenient for calculating the water seepage rate;

[0042] At the same time, the upper end surface of the bottom plate 4 of the device is flat, and a counterweight can be added;

[0043] The bottom plate 4 is also provided with air holes 10 , which are communicated with the water injection groove 8 .

[0044] After the waterproof material is filled, the space in the water injection groove 8 is a closed space. Water needs to be injected, but the air in the water injection groove 8 needs to be discharged. The air hole 10 is to facilitate the discharge of gas so that water can be injected smoothly.

[0045] The above description is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by any technician in the field of the present invention are included in the patent scope of the present invention.
