Description

Technical Field

[0001] This application relates to a structure for preventing soil erosion in dams. Background Technology

[0002] As a primary protective measure for rivers and reservoirs, the stability of dams is paramount. Soil erosion is a major cause of dam damage and requires particular attention during dam protection. Two aspects need to be considered when preventing soil erosion: the surface structure, which is currently often achieved through greening or composite greening netting; and the internal structural consolidation, typically achieved through driven pile foundations. However, existing pile foundation structures have relatively poor consolidation effects, especially in relatively soft soil conditions, leading to problems such as displacement. Utility Model Content

[0003] To address the aforementioned problems, this application proposes a soil-resistant structure for dams, comprising an embedded body with several external insertion holes at its lower part, an internally threaded section in its middle, an internally threaded rod threadedly connected to the middle of the internally threaded section, several hinged extension rods hinged to the lower part of the internally threaded rod, and a guide cone at the bottom of the internally threaded section. The guide cone engages with the external insertion holes to allow the hinged extension rods to extend out of the external insertion holes. This application strengthens the connection with the ground by embedding or inserting the embedded body into the dam and utilizing the hinged extension rods extending beyond the external insertion holes from below the internally threaded rod. Even in soft soil conditions, this provides a good deep-layer solidification effect for the dam.

[0004] Preferably, a neck is provided at the bottom of the internally threaded rod, and several pairs of hinge plates are provided on the side of the neck. The hinged extension rod is hinged between the hinge plates through a hinge connecting rod.

[0005] Preferably, a sleeve is fitted on the outer side of the neck, and the hinge plate is disposed on the sleeve. This application uses a sleeve for connecting the neck, which simplifies assembly. The ends of each hinge extension rod are centrally arranged, and one of the ends can be magnetized or bonded together to facilitate the screwing of the internal thread rod within the internal thread section during use.

[0006] Preferably, an internal operating hole is provided at the upper part of the internally threaded rod.

[0007] Preferably, a drill bit is provided at the bottom of the embedded body.

[0008] Preferably, several positioning extension rods are evenly distributed on the top of the embedded body.

[0009] Preferably, several external through holes are provided on the side of the embedded body corresponding to the internal thread section. A storage shell is disposed within the external through holes. The side of the storage shell adjacent to the internal thread section protrudes to the outside of the internal thread section. A rubber sealing plate is provided on the outside of the embedded body corresponding to the external through holes. A discharge port is provided on the storage shell corresponding to the rubber sealing plate. The storage shell and the rubber sealing plate are abutted against each other. Soil stabilizer is disposed inside the storage shell. This application, by setting a storage shell and pre-installing it inside the embedded body through the external through holes, allows the internal thread rod to push out the storage shell during use, thereby discharging the soil stabilizer inside. After the soil stabilizer flows out, it stabilizes the surrounding soil, thereby further expanding the soil area involved in this application and enhancing the stabilization effect.

[0010] Preferably, the embedded body is provided with an external assembly groove for assembling the rubber sealing plate at the position corresponding to the rubber sealing plate.

[0011] Preferably, the external insertion hole is positioned at an angle downwards.

[0012] This application can bring the following beneficial effects:

[0013] 1. This application involves embedding or inserting the embedded body into the dam, and then using the hinged extension rod below the internal threaded rod to extend out of the external insertion hole to strengthen the connection with the ground. Even in the case of soft foundation, it can achieve a better deep solidification effect for the dam.

[0014] 2. This application uses a sleeve ring for necking connection, which makes assembly simpler. The ends of each hinged extension rod are centrally arranged, and one of the ends can be magnetized or bonded together to facilitate the screwing of the internal thread rod in the internal thread section during use.

[0015] 3. This application sets up a storage shell and pre-installs it inside the embedded body through an external through hole. During use, the internal threaded rod pushes the storage shell out, thereby pushing out the soil stabilizer inside. After the soil stabilizer flows out, it stabilizes the surrounding soil, thereby further expanding the area of ​​soil involved in this application and enhancing the stabilization effect of this application.

[0023] To clearly illustrate the technical features of this solution, the following detailed description, in conjunction with the accompanying drawings, will explain this application in detail.

[0024] In the first embodiment, such as Figure 1-2 As shown, a structure for preventing soil erosion in dams includes an embedded body 1, with several external insertion holes 2 at the lower part of the embedded body 1, an internal threaded section 3 in the middle of the embedded body 1, an internal threaded rod 4 threadedly connected to the middle of the internal threaded section 3, several hinged extension rods 5 hingedly connected to the lower part of the internal threaded rod 4, and a guide cone 6 at the bottom of the internal threaded section 3. The guide cone 6 is configured to cooperate with the external insertion holes 2 so that the hinged extension rods 5 can extend out of the external insertion holes 2.

[0025] In use, the embedded body 1 is buried or drilled into the embankment 20. It can assist in the installation of anti-water and soil erosion nets, green plants, etc. Then, the internal thread rod 4 is screwed inward relative to the internal thread section 3. In order to avoid the hinged extension rod 5 on the internal thread rod 4 from affecting the screwing in (in fact, since it is a hinged setting, it generally will not affect it), the end of the hinged extension rod 5 can be magnetized or glued for preliminary fixation. After the end of the internal thread rod 4 touches the guide cone 6, each hinged extension rod 5 enters the adjacent external insertion hole 2 and extends into the embankment 20.

[0026] In the second embodiment, as Figure 1-6 As shown, a structure for preventing soil erosion in dams is characterized by: including an embedded body 1, with a plurality of external insertion holes 2 provided at the lower part of the embedded body 1, an internal threaded section 3 provided at the middle part of the embedded body 1, an internal threaded rod 4 threadedly connected at the middle part of the internal threaded section 3, a plurality of hinged extension rods 5 hingedly provided at the lower part of the internal threaded rod 4, and a guide cone 6 provided at the bottom of the internal threaded section 3. The guide cone 6 is configured to cooperate with the external insertion holes 2 so that the hinged extension rods 5 can extend out of the external insertion holes 2.

[0027] A neck 7 is provided at the bottom of the internally threaded rod 4, and several pairs of hinge plates 8 are provided on the side of the neck 7. The hinged extension rod 5 is hinged between the hinge plates 8 through a hinged connecting rod 9. A sleeve ring 10 is fitted on the outside of the neck 7, and the hinge plates 8 are mounted on the sleeve ring 10.

[0028] An internal operating hole 11 is provided at the upper part of the internally threaded rod 4. A lower drill bit 12 is provided at the bottom of the embedded body 1. Several positioning extension rods 13 are evenly distributed at the top of the embedded body 1. Several external through holes 14 are provided on the side of the embedded body 1 corresponding to the internally threaded section 3. A storage shell 15 is provided in the external through holes 14. The side of the storage shell 15 adjacent to the internally threaded section 3 protrudes to the outside of the internally threaded section 3. A rubber sealing plate 16 is provided on the outside of the embedded body 1 corresponding to the external through holes 14. A discharge port is provided on the storage shell 15 corresponding to the rubber sealing plate 16. The storage shell 15 and the rubber sealing plate 16 are abutted together. Soil stabilizer 17 is provided in the storage shell 15. An external assembly groove for assembling the rubber sealing plate 16 is provided on the embedded body 1 corresponding to the position of the rubber sealing plate 16. The external insertion hole 2 is obliquely downward.

[0029] In use, the embedded body 1 is buried or drilled into the embankment 20. It can assist in the installation of anti-water and soil erosion nets, green plants, etc. Then, the internal threaded rod 4 is screwed inward relative to the internal threaded section 3. In order to avoid the hinged extension rod 5 on the internal threaded rod 4 from affecting the screwing in (in fact, since it is a hinged setting, it generally will not affect it), the end of the hinged extension rod 5 can be magnetized or bonded for preliminary fixation. After the end of the internal threaded rod 4 touches the guide cone 6, each hinged extension rod 5 enters the adjacent external insertion hole 2 and extends into the embankment 20. At the same time, when the internal threaded rod 4 touches the storage shell 15, the storage shell 15 and the rubber sealing plate can be pushed out, and then the soil solidifying agent inside can be pushed out. After the soil solidifying agent flows out, it solidifies the surrounding soil, thereby further expanding the soil area involved in this application and strengthening the solidification effect of this application.

[0030] The above are merely embodiments of this application and are not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
