Description

Technical Field

[0001] The utility model belongs to the technical field of geological disaster prevention equipment, in particular to a slope soil fixing device for preventing mountain landslides. Background Art

[0002] The rock wall layer corresponding to the hill has a soil structure and vegetation on the soil surface. The vegetation can be easily destroyed by climatic factors. Without vegetation protection, the soil layer on the rock wall is prone to natural disasters in rainy weather, the most common of which is mudslides, which cause considerable trouble to the roads, farmlands and residents at the foot of the mountain.

[0003] For some slopes with large slopes and serious vegetation damage, it is possible to make an estimate and preventively reinforce the slopes to prevent mudslides and mountain rolling stones from sliding down the slopes. The existing reinforcement method is to fix them with anchor rods. The anchor rods cooperate with the positioning plates to compact the slopes and have a certain effect. However, the anchor rods can easily shake in the soil, resulting in the instability of the anchor rods themselves. Therefore, the utility model prepares a slope soil fixing device, which is positioned and fixed by steel cables to reduce the instability caused by rainwater infiltration. Utility Model Content

[0004] The utility model aims to provide a slope soil fixing device for preventing landslides, which is positioned and fixed by steel cables to reduce the self-instability phenomenon caused by rainwater infiltration.

[0007] The screw is fixed at one end of the steel cable, and a limiting cone is installed at the other end. The limiting cone is a shuttle-shaped structure, thick in the middle and sharp at both ends. The other end of the steel cable is fixed to the middle of the limiting cone.

[0008] The utility model comprises an inserting rod for guiding the limiting cone to be inserted into the slope soil.

[0009] Furthermore, a blocking strip is vertically fixed to the side of the pressure strip, and the blocking strip is integrally arranged with the pressure strip. The pressure strip has a weight-reducing hole, and the pressure strip also has a pressing plate, and the positioning hole is opened on the pressing plate. The pressing plate is in the shape of a strip, and has a plate structure, and one side overlaps and abuts against the upper side of the pressure strip, so as to cooperate with the nut.

[0010] Furthermore, the limiting cone has a notch from the center to the tip of one side, a rotating shaft is installed in the notch, the rotating shaft is sleeved with a shaft sleeve, and the end of the steel cable is fixed to the shaft sleeve. The end of the insertion rod has a conical groove body matching the tip of the limiting cone, which is used to accommodate and install the tip of the limiting cone.

[0011] The screw has a slot for receiving the end of the cable.

[0012] The utility model has the following beneficial effects: the axis of the screw rod is automatically stretched through the rotation of the nut, the steel cable is tightened, and the steel cable pulls the limiting cone so that the tips at both ends of the limiting cone penetrate into the side soil; because the steel cable is connected to the middle position of the limiting cone, the limiting cone adjusts its position under the pulling state, which is perpendicular to the pulling direction of the steel cable, thereby fixing the pressure plate strip; multiple steel cables are fixed at the same time, and the pressure plate strip is pressed against the slope soil, thereby improving the pressing effect and preventing the slope soil from loosening.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] like Figure 1-3As shown: A slope soil fixing device for preventing landslides, including a pressure plate strip 1, which is in a strip shape and a plate structure. The pressure plate strip 1 is provided with positioning holes 61 along the length direction, which are located at the center line of the pressure plate strip and are arranged in rows. The positioning holes 61 are circular perforations, and are used for screw rods 2 to pass through. The screw rod 2 is a cylindrical rod structure with an external thread, one end of which is used to cooperate with a nut 5 for fixing, and the other end is fixed with a steel cable 3;

[0022] One end of the steel cable 3 is fixed with the screw rod 2, and the other end is installed with a limiting cone 4. The limiting cone 4 is a shuttle-shaped structure, thick in the middle and sharp at both ends. The other end of the steel cable 3 is fixed to the middle of the limiting cone 4;

[0023] It comprises an insertion rod 7 for guiding the limiting cone 4 to be inserted into the slope soil.

[0024] During installation, the limiting cone is fixed by the end of the insertion rod, and then the rigidity of the insertion rod is used to insert the coating to the deep end of the coating. The insertion rod is pulled out, and the limiting cone remains deep in the soil. Then the screw rod passes through the positioning hole, and the nut is installed on the part passing through the positioning hole. The screw rod is automatically stretched axially by rotating the nut, and the steel cable is tightened. The steel cable pulls the limiting cone so that the tips of both ends of the limiting cone penetrate into the soil on the side. Since the steel cable is connected to the middle position of the limiting cone, the limiting cone adjusts its position under pulling state, which is perpendicular to the pulling direction of the steel cable, thereby fixing the pressure plate. Multiple steel cables are fixed at the same time to press the pressure plate against the slope soil, thereby improving the pressing effect and preventing the slope soil from loosening.

[0025] Due to the flexibility of the steel cable, it is not easy to shake when soaked in rainwater, thus improving the stability of the installation.

[0026] like Figure 2 As shown: a blocking strip 12 is vertically fixed on the side of the pressure plate strip 1, and the blocking strip 12 is integrally arranged with the pressure plate strip 1. The blocking strip is used to resist rolling stones on the hillside when the pressure plate strip is fixed. It can also have a certain blocking effect on preventing rolling stones when the slope soil is compacted. The cross-section of the overall plate structure is L-shaped, which has the function of improving strength. The pressure plate strip 1 has a weight-reducing hole 11. The pressure plate strip 1 also has a pressing plate 6. The positioning hole 61 is opened on the pressing plate 6. The pressing plate 6 is strip-shaped. The plate structure has a single side that overlaps and abuts against the upper side surface of the pressure plate strip 1, and is used to cooperate with the nut 5. The weight-reducing hole saves materials and increases the pressing surface. In order to prevent the strength of the pressure plate strip itself from being reduced, a pressing plate is installed. The pressing plate is made of metal and has a better force-bearing effect. It is used to cooperate with the nut to prevent the pressure plate strip from deforming when the nut is rotating.

[0027] like Figure 4As shown: the limiting cone 4 is provided with a notch 41 from the center to the tip of one side, a rotating shaft is installed in the notch 41, a shaft sleeve 31 is sleeved on the rotating shaft, and the end of the steel cable 3 is fixed to the sleeve 31. It is convenient for the connection end between the steel cable and the limiting cone to rotate, and when the steel cable is pulled, it is convenient for the limiting cone to shift. The end of the insertion rod 7 has a conical groove body 71 that matches the tip of the limiting cone 4, which is used to accommodate and install the tip part of the limiting cone 4. Improve the support stability. The screw rod 2 has a slot 21 for accommodating the end of the steel cable 3. It is used to insert the end of the steel cable and fix it by welding.

[0028] This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present invention, so that those skilled in the art can better understand and utilize the present invention.
