Description

Technical Field

[0001] The utility model relates to the technical field of slope waterproofing, in particular to an assembled slope steel nail water-stopping component. Background Art

[0002] Slope waterproofing is an important engineering measure, especially in civil engineering and geological engineering. The main purpose is to prevent the influence of water on the stability of the slope and avoid geological disasters such as landslides and collapses caused by water seepage. It is a very common way to waterproof the slope using waterproof membranes (such as polyethylene, asphalt waterproof membranes, etc.) to cover the surface of the slope to prevent rainwater from seeping in. In order to prevent the waterproof membrane from sliding and to improve the stability of the waterproof membrane, the waterproof membrane needs to be fixed. The traditional way is to use steel bars to directly penetrate the waterproof membrane and then insert it into the soil of the slope, which can easily cause water seepage at the perforations and scour the slope. Utility Model Content

[0003] In view of the deficiencies existing in the prior art, the utility model provides an assembled slope steel nail water-stopping assembly, which solves the problem in the prior art that after the waterproof membrane is fixed by directly using steel bars to penetrate the waterproof membrane, water seepage will occur at the perforations, and the seepage water will flush the slope and affect the overall slope stability.

[0004] According to an embodiment of the utility model, an assembled slope steel nail water-stop assembly includes a threaded rod, on which a water-stop ring and a first nut are sequentially sleeved, the first nut is threadedly connected to the threaded rod, the water-stop ring is a truncated cone structure with an isosceles trapezoidal cross-section, and an accommodating cavity is provided at the end thereof away from the first nut.

[0005] Compared with the prior art, the utility model has the following beneficial effects: one end of the threaded rod is inserted into the soil of the slope after passing through the waterproof membrane, and then the water stop ring penetrated on the threaded rod is pressed against the waterproof membrane by rotating the first nut. Since the accommodating cavity of the water stop ring is covered at the perforation of the threaded rod and the waterproof membrane, external rainwater is blocked by the water stop ring when passing through the water stop ring. At this time, this part of the rainwater will be guided by the annular edge where the water stop ring and the waterproof membrane are tightly attached, and it is difficult for some rainwater to enter the perforation to penetrate the distance of the contact surface where the water stop ring and the waterproof membrane are tightly attached, thereby achieving a good water-stopping effect. While the threaded rod fixes the waterproof membrane, it effectively prevents external rainwater from penetrating into the soil of the slope from the perforation of the threaded rod.

[0006] Furthermore, a water absorbing member is provided at one end of the water stop ring away from the first nut.

[0007] Furthermore, the water absorbing member is an expansion water stop strip.

[0008] Furthermore, an annular installation groove is provided on the end surface of the water stop ring away from the first nut, and the expansion water stop strip is embedded in the annular installation groove.

[0009] Furthermore, it also includes a pointed head, which is arranged at the end of the threaded rod.

[0010] Furthermore, the pointed head includes: a connecting portion and a sharp portion, the connecting portion and the sharp portion are integrally formed, a groove is provided at the end of the threaded rod, an internal thread is provided in the groove, and an external thread matching the internal thread is provided on the sharp portion.

[0011] Furthermore, it also includes a second nut, which is also threadedly connected to the threaded rod.

[0012] As another embodiment, further, it includes a rubber gasket, which is also sleeved on the threaded rod, and the rubber gasket is located on the side of the water stop ring away from the first nut. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0019] like Figure 1—3, an embodiment of the utility model proposes an assembled slope steel nail water-stop assembly, including a threaded rod 1, on which a water-stop ring 2 and a first nut 3 are sequentially sleeved, the first nut 3 being threadedly connected to the threaded rod 1, the water-stop ring 2 being a truncated cone structure with an isosceles trapezoidal cross-section, and an accommodating cavity 4 is provided at the end thereof away from the first nut 3. When in use, after laying the waterproof membrane 10 on the slope 11, the threaded rod 1 (the thread line is hidden) is inserted into the waterproof membrane 10 and then inserted into the soil of the slope 11, and then the water stop ring 2 and the first nut 3 are inserted in sequence. The side of the water stop ring 2 with the cavity is tightly attached to the waterproof membrane 10, so that the accommodating cavity 4 of the water stop ring 2 is covered at the perforation of the threaded rod 1 and the waterproof membrane 10, and then the first nut 3 is rotated so that the first nut 3 is pressed against the side wall of the water stop ring 2, that is, the side of the water stop ring 2 away from the accommodating cavity 4, so that the waterproof membrane 10 is fixed on the slope 11 through the first nut 3, the water stop ring 2 and the threaded rod 1. The water stop ring 2 isolates the perforation of the threaded rod 1 from the outside, reduces the penetration and scouring of the slope 11 by seepage, and ensures the stability of the slope 11. The threaded rod 1 and the nut are common materials on the construction site, and workers can make them quickly when needed, which is convenient and fast.

[0020] like Figure 1 As shown in FIG. 3 , further, a water absorbing member 5 is provided at one end of the water stop ring 2 away from the first nut 3. The end of the water stop ring 2 away from the first nut 3 is the end face where the accommodating cavity 4 is located. Since the water stop ring 2 is in close contact with the waterproof membrane 10, the close contact area will be invaded by rainwater. By providing the water absorbing member 5, the rainwater intruding between the water stop ring 2 and the waterproof membrane 10 is absorbed to prevent this part of rainwater from penetrating into the soil from the perforation. Specifically, the water absorbing member 5 can be a material that can absorb and retain liquid, such as sponge or cotton.

[0021] Furthermore, the water-absorbing member 5 is an expansion water-stop strip. Specifically, the water-absorbing member 5 is an expansion water-stop strip that expands when in contact with water. The expansion water-stop strip has the characteristics of rubber. When the water-stop ring 2 is pressed against the waterproof membrane 10 through the first nut 3, the expansion water-stop strip is in close contact with the waterproof membrane 10. When rainwater intrudes, the expansion water-stop strip expands when in contact with water, and fills the gap between the waterproof membrane 10 and the water-stop ring 2 more densely, making it more difficult for rainwater to enter the accommodating cavity 4 of the water-stop ring 2, thereby achieving a good water-stopping effect.

[0022] like Figure 3 As shown, further, an annular mounting groove 6 is provided on the end surface of the water stop ring 2 away from the first nut 3, and the expansion water stop strip is embedded in the annular mounting groove 6. The expansion water stop strip is connected to the water stop ring 2 through the annular mounting groove 6, and is not easy to deviate when the expansion water stop strip abuts against the waterproof membrane 10. The expansion water stop strip can also be produced in specifications, which is convenient for replacing the expansion water stop strip of fixed specifications.

[0023] like Figure 1 and 3As shown, further, a pointed head 7 is included, and the pointed head 7 is arranged at the end of the threaded rod 1. Different soil environments make it difficult for the threaded rod 1 to be inserted therein, and it is also easy to deviate. By arranging the pointed head 7 at the end of the threaded rod 1, the threaded rod 1 can be inserted into the soil more easily, and it is not easy to deviate during insertion.

[0024] like Figure 3 As shown, further, the pointed head 7 includes: a connecting portion and a sharp portion, the connecting portion and the sharp portion are integrally formed, a groove is provided at the end of the threaded rod 1, an internal thread is provided in the groove, and an external thread matching the internal thread is provided on the sharp portion. The pointed head 7 is threadedly connected to the end of the threaded rod 1 through the connecting portion, and the worker can decide whether to use the pointed head 7 according to the soil conditions. As another embodiment, a thread groove adapted to the threaded rod 1 can also be provided on the connecting portion, so that the threaded rod 1 does not need to be processed, simplifying the process. Preferably, a square structure is provided at the connection between the pointed head 7 and the connecting portion, so that the worker can screw the pointed head 7 to screw the pointed head 7 to the threaded rod 1.

[0025] like Figure 1 —3, further, it also includes a second nut 8, which is also threadedly connected to the threaded rod 1. Through the double-nut locking method of the first nut 3 and the second nut 8, the water stop ring 2 is more stable when it is pressed against the waterproof membrane 10, and the first nut 3 is not easy to loosen. In actual construction, the threaded rod 1, the first nut 3, and the second nut 8 are often used as a set. When the device is not in use, the first nut 3 and the second nut 8 can be screwed to the two ends of the water stop ring 2 respectively, so that the water stop ring 2 will not slip off the threaded rod 1, which is convenient for storing the various components as a set.

[0026] like Figure 4 As shown, as another embodiment, further, a rubber gasket 9 is included, which is also sleeved on the threaded rod 1 and located on the side of the water stop ring 2 away from the first nut 3. Since the surface of the slope 11 is uneven, some depressions will appear after the waterproof membrane 10 is covered, and the rubber gasket 9 can fill this part of the depression, thereby improving the water stopping ability of the water stop ring 2.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
