Abstract
Description
Technical Field
[0001] This utility model relates to the field of seepage detection technology, and in particular to a seepage detection device for engineering supervision. Background Technology
[0002] In road engineering supervision, the permeability of asphalt pavement directly affects road durability and safety. Current standards require the assessment of pavement density through permeability coefficients. Specialized permeability testing equipment is needed when conducting permeability tests on asphalt roads. Currently, the conventional permeability testing equipment is a permeability meter. When using it, it is placed on the asphalt pavement to be tested, the top measuring cylinder is filled with water, and the valve at the bottom is opened. The rate and amount of water loss in the measuring cylinder are observed to determine the pavement's permeability.
[0003] It should be noted that before placing the aforementioned permeability testing instrument on the asphalt pavement, a layer of sealant (plaster) needs to be manually applied to the testing location on the asphalt pavement, forming a ring shape. The size of this ring-shaped sealant must correspond to the size of the permeability testing instrument's base. Then, the base of the permeability testing instrument and the ring-shaped sealant are aligned and compacted to complete the installation. This ensures a tight seal between the permeability testing instrument and the asphalt pavement, guaranteeing accurate test results. However, the above-mentioned method of manually aligning the base of the permeability testing instrument with the pre-applied sealant during installation is prone to errors. Furthermore, during the compaction process, the sealant, under pressure, may spread outwards, potentially causing some sealant to seep into the center of the base, clogging the seepage holes or reducing the seepage area in the center of the base, thus affecting the accuracy of the test results. Therefore, we propose a permeability testing device for engineering supervision. Utility Model Content

[0012] This utility model provides a seepage detection device for engineering supervision. It has the following beneficial effects:
[0013] (1) The seepage detection device used in the project supervision optimizes the sealing effect of the mortar through the synergistic effect of the first and second retaining rings. The first retaining ring is located on the outer side of the bottom surface of the base, which can limit the mortar from spreading outward. The second retaining ring slides in the relief groove through the second reset spring, which not only prevents the mortar from being squeezed into the lower end of the connecting pipe and causing blockage, but also allows for adaptive height adjustment when under pressure, ensuring a flat sealing surface and preventing the mortar from spreading and causing blockage at the end of the connecting pipe or affecting the seepage area.
[0014] (2) The seepage detection device used in the project supervision has a design that combines a sealing ring and a threaded ring to provide a visual boundary for the application of putty, which not only avoids the waste of putty, but also increases the contact area through the flexible sealing ring, thereby further improving the sealing reliability.

Detailed Implementation
[0023] 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.
[0024] like Figure 1-5 As shown, a seepage detection device for engineering supervision includes a base 1. Two symmetrically arranged support columns 3 are fixedly connected to the upper surface of the base 1. The upper ends of the two support columns 3 are connected to an upper pressure plate 2. A measuring cylinder 4 is fixedly installed at the center of the upper surface of the upper pressure plate 2. A connecting pipe 5 is fixedly connected between the upper pressure plate 2 and the base 1, communicating with the measuring cylinder 4 and the base 1. A valve 6 is movably installed on the connecting pipe 5. A first retaining ring 15 is provided inside the base 1. A clearance groove 16 is formed on the upper surface of the first retaining ring 15. A second retaining ring 18 is slidably installed inside the clearance groove 16. The upper end face of the second retaining ring 18 is fixedly connected to the bottom surface of the base 1. Multiple equidistantly arranged second return springs 17 are fixedly connected to the bottom surface of the second retaining ring 18. The ends of the second return springs 17 are connected to the bottom of the clearance groove 16. The inner wall is fixedly connected; firstly, the staff evenly applies the putty to the bottom surface of the base 1, with the putty application area located outside the first retaining ring 15. Then, the staff places the device in the pre-measured and cleaned test position. At this time, the bottom surface of the first retaining ring 15 located on the bottom surface of the base 1 first contacts the asphalt pavement. Then, under the action of external force, the base 1 is pressed down, and the putty is squeezed to seal the bottom perimeter of the base 1 with the asphalt pavement. During the process of the putty being squeezed, the first retaining ring 15 continuously blocks the putty to prevent it from being excessively dispersed. In addition, during the application and squeezing of the putty, the second retaining ring 18 prevents the putty from entering the center area of the bottom surface of the base 1, thus preventing the putty from clogging the lower end of the connecting pipe 5.
[0025] like Figure 2As shown, multiple sliding rods 12 are fixedly installed on the upper surface of the first retaining ring 15. The upper ends of the multiple sliding rods 12 all extend through the base 1 to the top of the base 1, and the ends of the multiple first retaining rings 15 are fixedly connected to a movable ring 8. Multiple first return springs 11 are fixedly connected between the movable ring 8 and the upper surface of the base 1. The number of first return springs 11 is the same as the number of sliding rods 12, and the sliding rods 12 are located inside the first return springs 11. After applying putty to the circumference of the bottom surface of the base 1, the lower end of the first retaining ring 15 located on the bottom surface of the base 1 is brought into contact with the asphalt pavement surface. Then, by pressing the base 1 downward, the putty is squeezed to seal the bottom surface of the base 1 and the asphalt pavement. After the water seepage test is completed, under the action of no external force, the elasticity of the multiple first return springs 11 can squeeze the first retaining ring 15 downward to the initial position below the bottom surface of the base 1, so that the staff can accurately place the device at the water seepage test position.
[0026] like Figure 4 As shown, the lower outer wall of the base 1 is fixedly connected with an annular extension edge 19, and the upper surface of the extension edge 19 is movably connected with two symmetrically arranged counterweights 9: the counterweights 9 are semi-circular ring structures, and the combination of the two counterweights 9 can make the extension edge 19 be evenly stressed.
[0027] like Figure 4 As shown, an annular sealing ring 13 is movably connected to the outer wall of the extension edge 19, and the sealing ring 13 is flexible. The sealing ring 13 provides a reference for the operator when applying putty to the bottom surface of the base 1. The putty is filled in the gap between the first retaining ring 15 and the sealing ring 13. When inexperienced users use the device, the sealing ring 13 can prevent the operator from applying too much putty and wasting it. At the same time, the sealing ring 13 can also increase the contact area between the lower end of the device and the putty, thus improving the sealing performance.
[0028] like Figure 4 As shown, a threaded ring 14 is fixedly connected to the upper end of the sealing ring 13, and the threaded ring 14 is threadedly connected to the outer wall of the extension edge 19; the threaded ring 14 and the extension edge 19 are detachably connected, and the sealing ring 13 can be disassembled through the threaded ring 14.
[0029] like Figure 2 As shown, pressure handles 7 are fixedly installed on both sides of the upper pressure plate 2, and the outer wall of the pressure handles 7 is provided with multiple protrusions; the operator presses the device down by holding the two pressure handles 7, and the bottom surface of the auxiliary base 1 is sealed with the asphalt road surface. The multiple protrusions can increase the friction between the user's hand and the outer wall of the pressure handles 7.
[0030] like Figure 2As shown, multiple limiting rods 10 are fixedly installed on the upper surface of the extension edge 19, and multiple through holes for cooperating with the limiting rods 10 are opened through the weight block 9. The multiple limiting rods 10 are respectively inserted into the through holes opened on the weight block 9. The insertion of the multiple limiting rods 10 into the through holes provided on the weight block 9 can make the weight block 9 stably placed on the upper surface of the extension edge 19 and apply downward pressure to the extension edge 19.
[0031] The working principle of this utility model is as follows: When in use, this device is used in conjunction with putty to conduct water seepage detection on asphalt roads. The operator can apply putty to the bottom surface of the base 1, so that the putty is evenly distributed on the outside of the first retaining ring 15. Under the blocking effect of the second retaining ring 18, the putty can be prevented from entering the central area of the bottom surface of the base 1, avoiding the risk of the putty clogging the lower end of the connecting pipe 5. Then, the operator places the device in the pre-measured and cleaned detection position. At this time, the bottom surface of the first retaining ring 15 located on the bottom surface of the base 1 will first contact the asphalt road surface. Then, the operator holds the two pressure handles 7 and presses the base 1 downward. The extension edge 19, which is integrally connected to the base 1, simultaneously squeezes the putty downward to seal the bottom surface of the base 1 and the asphalt road surface. During the process of the putty being squeezed, the first retaining ring 15 can continuously block the putty to prevent the putty from being too dispersed. Then, the user installs the two weight blocks 9 on the upper surface of the extension edge 19, so that the extension edge 19 is evenly and continuously subjected to downward pressure, ensuring the sealing of the bottom surface of the base 1.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
