Description

TECHNICAL FIELD

[0001] The present application relates to the field of building, in particular to an anti-pull soil anchor. BACKGROUND

[0002] In reality, it is often necessary to fix various objects on the soil, such as wind cable, road slope, and net before spraying grass on the soil. In fixing these objects, anchor nails are usually used in the form of being driven into. Whether in engineering construction or in daily life, soil anchor is very common. At present, the form of soil anchor is usually in the form of a columnar steel nail to facilitate driving in, but the friction between such structure and the soil is limited, which cannot provide sufficient anti-pull force, often resulting in that the fixed object is not firm enough. Therefore, the current technology has two ideas to improve the anti-pull force:

[0003] 1. A grouting channel is arranged around the anchor nail, and cement slurry is injected after the anchor nail is driven in, and the cement slurry is anchored in the soil after solidification. By using this form, the slurry and the anchor nail are still independent structures in essence, and it is still difficult to provide a large anti-pull force. Moreover, the grouting equipment is complex, and the grouting amount will be large in some high-permeability soil layers, causing great waste and environmental pollution. Or, when encountering low-permeability soil, it is difficult to inject slurry, and there are problems in applicability.

[0004] 2. A barb structure is arranged around the anchor nail. If the barb is in a fixed structure, it will be very difficult to drive in, and will disturb the soil, affecting its stability. If the barb is in a rotating form, although it is beneficial to driving in, it can move after driving in, and the anti-pull force will not be greatly strengthened. SUMMARY

[0037] Please refer to Figure 1 , combined with reference Figures 2 to 9 The present application provides a kind of anti-pulling soil anchor nail, it mainly includes anchor nail body 1;Wherein, anchor nail body 1 bottom end is provided with integrally formed cone piercing part 2, cone piercing part 2 is conical and top is provided with gas outlet 8, high-pressure tank body 3 is installed in the inner cavity of cone piercing part 2, high-pressure tank body 3 is installed at the gas outlet 8 of cone piercing part 2, and top is provided with rubber sealing pad;At the same time, the inside of anchor nail body 1 is provided with main channel 4 being communicated with cone piercing part 2, main channel 4 is communicated with gas outlet 8, main channel 4 is provided with movable needle 5, needle 5 is directly above high-pressure tank body 3 and one end extends the top end of anchor nail body 1, when it moves to the rubber sealing pad on high-pressure tank body 3 downwards, it can pierce high-pressure tank body 3, so that high-pressure gas in high-pressure tank body 3 enters main channel 4 through gas outlet 8.In addition, the circumference of main channel 4 is communicated with multiple upwardly inclined and spaced branch channels 6, and each branch channel 6 is movably provided with expandable or retractable anchor nail 7, one end of anchor nail 7 can move out of branch channel 6 and anchor in the surrounding land.The anchor nail body 1 is provided with multiple anchor nails 7 in its inside, before and during driving into soil body, these anchor nails 7 are retracted in the inside of anchor nail body 1, and will not affect the driving process.

[0038] It should be noted that main channel 4 is provided along the length direction of anchor nail body 1, and it extends from one end of anchor nail body 1 connected with cone piercing part 2 to the middle position of anchor nail body 1.At the same time, the end of needle 5 close to high-pressure tank body 3 is conical, and the other end extends the top end of anchor nail body 1 and is screw-connected with cap 9.In addition, multiple branch channels 6 all extend from main channel 4 to the outer wall of anchor nail body 1, and they are gradually inclined from the direction close to high-pressure tank body 3 to the direction away from high-pressure tank body 3.

[0039] Further, at least one exhaust passage 10 is arranged in the anchor body 1, and one end of the exhaust passage 10 is communicated with the branch passage 6, and the other end extends to the other end of the anchor body 1 and is communicated with the pressure relief port 11 on the outer wall of the anchor body 1.

[0040] It should be noted that in the present embodiment, the exhaust passage 10 can be arranged as multiple, and is arranged in parallel and spaced apart with the main passage 4, and the multiple exhaust passages 10 are distributed on the outer side of the main passage 4 in a spaced apart manner, and each exhaust passage 10 is sequentially communicated with multiple branch passages 6 on the same straight line.

[0041] Further, the anchor nail 7 comprises an anchor body 12, one end of the anchor body 12 is in a conical shape, and on the opposite sides of the anchor body 12, expandable or retractable anchor folding fans are installed, the anchor folding fan comprises a flexible folding layer 13 and multiple flat head rods 14; wherein the flexible folding layer 13 is foldably installed on the side wall of the anchor body 12; multiple flat head rods 14 are installed on the flexible folding layer 13 in a spaced apart manner, and one end is hingedly connected to the side wall of the anchor body 12 in a spaced apart manner along the length direction of the anchor body 12, and the other end extends out of the flexible folding layer 13; the length of the multiple flat head rods 14 gradually decreases from the direction close to the high-pressure tank body 3 to the direction away from the high-pressure tank body 3. At the same time, the flat head structure is in a flat shape and is arranged at an angle between the anchor body 12, and the free end is in a conical shape.

[0042] Meanwhile, the anchor body 1 is internally provided with a high-pressure tank 3, which can be loaded with high-pressure gas, and the upper part of the high-pressure tank 3 is sealed by a flexible material such as rubber, and the upper part of the sealing material is provided with a needle 5, which protrudes upward from the anchor body 1 and is exposed, and the exposed part is provided with a cap 9, which is screwed in when the anchor body 1 is stored and driven into the soil, so as to prevent accidental contact with the needle 5 and facilitate hammering. After the anchor body 1 is driven into the soil, the cap 9 is removed, and the needle 5 is struck, which will pierce the rubber sealing pad on the upper part of the high-pressure tank 3, and the high-pressure gas will be sprayed out of the anchor body 1; in addition, it can also use the way of hitting the needle to hit the primer to ignite the gunpowder to generate high-pressure gas in the high-pressure tank 3. The high-pressure gas sprays the anchor nail 7 along the main channel 4 and the branch channel 6 arranged inside the anchor body 1, and the anchor nail 7 expands to form a fan-shaped structure after contacting the external soil, and is embedded in the surrounding soil. When the anchor nail 7 sprays a certain length, the hole at the tail of the anchor nail 7 is connected with the pressure relief port 11 at the top of the anchor body 1, so that the excess gas is discharged from the pressure relief port 11, thereby preventing the anchor nail 7 from being pulled out, and also preventing the internal pressure of the device from being too high. In order to further increase the anchoring force of the soil anchor, the anchor nail 7 is designed to be a fan-shaped structure that can be expanded, and before use, the anchor nail 7 is stored in the branch channel 6 of the anchor body 1, and after being pushed out by the high-pressure gas, the pointed and flat structure at the front end is beneficial to piercing into the soil and increasing the lateral thrust to facilitate expansion.

[0043] The working principle of the structure is:

[0044] Drive the anchor body 1 into the soil (at this time, the cap 9 is above the needle 5 to facilitate hammering into the soil); remove the cap 9 and strike the needle 5 to pierce the high-pressure gas tank (or ignite the gunpowder); complete anchoring, and fix the object to be fixed at the upper part of the anchor body 1.

[0045] As can be seen from the above, in the anti-pull soil anchor, the anchor nail 7 can be sprayed out after the anchor body 1 is driven in, and the anchor nail 7 forms a fan-shaped body embedded in the soil after being sprayed out, which has very strong anti-pull ability and can ensure the stability of various objects fixed on the soil; at the same time, the structure is convenient to use and reliable, and has strong applicability, which can release high-pressure gas from the inside, which not only ensures the smooth pushing out of the anchor nail 7, but also ensures that the internal pressure of the device will not be overloaded, thereby preventing the anchor nail 7 from being pulled out; in addition, the anchor nail 7 can be conveniently stored in the inside of the anchor body 1 and can be pierced and expanded under pressure, which greatly increases the anchoring force. Furthermore, the structure can greatly improve the anchoring force of the soil anchor, has the characteristics of convenient use, easy to master, high efficiency, and more economical, and has good adaptability.

[0046] The above descriptions are only the preferred embodiments of the present application, and are not intended to limit the present application. The present application can have various modifications and changes for those skilled in the art. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
