Description

Technical Field

[0001] This utility model relates to a detection device, and more particularly to a road and bridge seepage detection device. Background Technology

[0002] Road bridges generally consist of several major parts, including roadbed, pavement, bridge, tunnel engineering, and traffic engineering facilities. Slab bridges are a common type of highway bridge with a large number of bridges and wide application. They have a simple structure and clear stress distribution. They can be constructed using reinforced concrete and prestressed concrete structures and can be made solid or hollow. They can be cast in situ to adapt to various shapes of curved, sloping, and skewed bridges. After construction, road bridges need to undergo seepage testing. Traditional seepage testing devices usually involve directly injecting water into the road bridge and observing changes in the water source to understand the seepage situation.

[0003] In existing technologies, the detection device can only draw a circle on the ground to be tested in advance using iron rings and chalk, and then apply waterproof material to the planned outer circle by smearing. This makes the operation cumbersome, the detection efficiency low, and increases inconvenience. Utility Model Content

[0004] The purpose of this invention is to provide a road and bridge seepage detection device to solve the existing problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a road and bridge seepage detection device, comprising a sealing ring, a storage groove formed at the lower edge of the sealing ring, a compression ring slidably installed in the storage groove, a sealing material filled in the storage groove, a threaded connection groove formed at the upper edge of the sealing ring, a threaded connection ring threadedly installed in the threaded connection groove, a lower connecting plate fixedly connected to the threaded connection ring, an infusion pipe fixedly connected to the lower connecting plate, an upper support plate fixedly connected to the upper end of the infusion pipe, a transparent storage tank fixedly connected to the upper support plate, and the transparent storage tank communicating with the lower opening of the lower connecting plate through the infusion pipe.

[0006] Preferably, the sealing ring has a through hole along its upper edge, and a connecting post is fixedly connected to the top of the compression ring, the connecting post passing through the through hole and through the sealing ring.

[0007] Preferably, a valve is fixedly connected to the infusion tube at the middle position.

[0008] Preferably, a counterweight ring is provided above the lower connecting plate, a connecting recess is provided below the counterweight ring, and a connecting protrusion is fixedly connected to the top of the counterweight ring. The connecting recess cooperates with the connecting post and the connecting protrusion.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] 1. By pre-filling the sealing material into the storage tank, the sealing ring is placed directly on the bridge surface. The threaded connection groove is used to squeeze the sealing material downwards. The sealing material is squeezed and seals the gap between the lower edge of the sealing ring and the bridge surface. Compared with the existing device, it is not necessary to draw a circle on the bridge surface in advance, apply sealing material, simplify the operation steps and improve the detection efficiency.

[0011] 2. By pressing the counterweight ring on top of the connecting column, the counterweight ring's own weight provides a certain downward pressure to the threaded connection groove. The downward pressure on the threaded connection groove will squeeze the sealing material in the storage tank. The pressure of the water in the transparent storage tank above the sealing ring keeps the internal and external pressures at the lower edge of the sealing ring relatively balanced, which can minimize or prevent the water in the sealing ring from overflowing and causing the test to fail.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-6This utility model provides a technical solution: a road and bridge seepage detection device, including a sealing ring 1, a storage trough 101 is provided on the lower edge of the sealing ring 1, a compression ring 103 is slidably installed in the storage trough 101, the storage trough 101 is filled with sealing material, a threaded connection groove 102 is provided on the upper edge of the sealing ring 1, a threaded connection ring 201 is threadedly installed in the threaded connection groove 102, a lower connecting plate 2 is fixedly connected to the threaded connection ring 201, an infusion pipe 202 is fixedly connected to the lower connecting plate 2, an upper support plate 204 is fixedly connected to the upper end of the infusion pipe 202, a transparent storage tank 205 is fixedly connected to the upper support plate 204, and the transparent storage tank 205 is connected to the lower opening of the lower connecting plate 2 through the infusion pipe 202.

[0021] In this embodiment, the sealing ring 1 is inverted so that the opening of the storage tank 101 faces upward. Sealing material is then pre-filled into the storage tank 101. The sealing ring 1 is then flipped over and fastened onto the bridge surface. The connecting post 104 presses down on the compression ring 103. The compression ring 103 moves downward and compresses the sealing material inside the storage tank 101, filling the gap between the lower edge of the sealing ring 1 and the bridge surface, thus sealing the gap. The compressed sealing material inside the sealing ring 1 is then scraped off using a scraper or similar tool. Finally, the threaded connecting ring 201 is rotated and installed into the threaded connecting groove 102. A sealing rubber ring is provided at the bottom to seal the gap between the threaded connecting ring 201 and the threaded connecting groove 102. At this time, the inside of the sealing ring 1 is in a sealed state. Add a certain amount of clean water into the transparent liquid storage tank 205. The clean water will flow into the lower opening of the lower connecting plate 2 through the infusion pipe 202 and finally into the sealed space inside the sealing ring 1. By observing and recording the rate at which the water level in the transparent liquid storage tank 205 drops, the rate of water seepage on the bridge surface can be calculated. Compared with the existing device, the sealing material is directly filled into the storage tank 101, eliminating the need to draw a circle on the bridge surface in advance, lay the sealing material, simplify the operation steps and improve the detection efficiency.

[0022] To prevent water leakage, the device employs the following technical solution: a through hole is provided along the upper edge of the sealing ring 1; a connecting post 104 is fixedly connected to the top of the compression ring 103; the connecting post 104 passes through the through hole and through the sealing ring 1; a valve 203 is fixedly connected to the middle of the infusion tube 202; a counterweight ring 3 is provided above the lower connecting plate 2; a connecting recess 301 is provided below the counterweight ring 3; a connecting protrusion 302 is fixedly connected to the top of the counterweight ring 3; and the connecting recess 301 cooperates with the connecting post 104 and the connecting protrusion 302.

[0023] The through-hole allows the connecting post 104 to pass through the sealing ring 1. The inner diameter of the counterweight ring 3 is larger than the outer diameter of the upper support plate 204, allowing the counterweight ring 3 to pass through the upper support plate 204 and be placed above the lower connecting plate 2. The connecting recess 301 cooperates with the connecting post 104, allowing the connecting post 104 to be inserted into its interior, connecting the connecting recess 301 and the connecting post 104 together. This restricts the sliding of the counterweight ring 3 and provides continuous downward pressure to the threaded connecting groove 102. The sealing ring 1 is pressurized by the clear water in the upper transparent storage tank 205, while the counterweight ring 3 presses down on the threaded connecting groove 102, squeezing the sealing material and causing the storage tank to... The sealing material inside 101 has a certain pressure. Under the condition of relatively balanced internal and external pressure, the leakage of water from the sealing ring 1 can be minimized or avoided. The connecting concave hole 301 and the connecting protrusion 302 cooperate with each other. The number of counterweight rings 3 can be adjusted according to the amount of water poured out, thereby changing the compressive force on the sealing material. In order to prevent the pressure inside 1 from decreasing due to the gradual seepage of water inside the transparent liquid storage tank 205, and the sealing material from being quickly squeezed into the interior of 1, the sealing material needs to be a waterproof putty, putty or other sealing material with poor fluidity. This will minimize the problem of the sealing material flowing into the interior of 1 and affecting the test results.

[0024] The working principle and usage process of this utility model are as follows: The sealing ring 1 is reversed so that the opening of the storage tank 101 faces upwards. Sealing material is pre-filled into the storage tank 101. Then, the sealing ring 1 is quickly flipped and fastened onto the bridge surface. The connecting column 104 presses down on the compression ring 103. The compression ring 103 moves downwards and squeezes the sealing material inside the storage tank 101, filling the gap between the lower edge of the sealing ring 1 and the bridge surface. Using a scraper or other tools, the squeezed sealing material inside the sealing ring 1 is scraped off. Finally, the threaded connecting ring 201 is rotated and installed into the threaded connecting groove 102. An appropriate counterweight ring 3 is passed through the upper support plate 204 and the transparent storage tank 205 is placed on the connecting column 104. Suitable clean water is added to the transparent storage tank 205. The valve 203 is opened to allow clean water to flow into the hollow space inside the sealing ring 1. After no more air bubbles overflow, clean water is added to the transparent storage tank 205 again. The descent speed of the clean water inside the transparent storage tank 205 can then be timed and observed and recorded.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
