Description

Technical Field

[0001] This invention belongs to the field of desertification control technology and relates to a feather-arrow type mechanical sand barrier and its method. Background Technology

[0002] Mechanical sand barriers refer to various forms of obstacles set up on the sand surface using materials such as firewood, grass, branches, clay, and pebbles. Their purpose is to control the direction, speed, and structure of wind and sand movement, change the wind erosion situation, prevent wind and sand, and change the effect of wind and micro-topography. It is one of the main measures for engineering sand control.

[0003] During the implementation of large-scale sand control projects, traditional sand barriers made of willow branches, rice straw, or reed stalks are difficult to standardize and control in terms of key parameters such as penetration depth and porosity. At the same time, due to the different strengths of the materials, the sand barrier structures have poor stability, short service life, and are easily damaged by wind erosion. Moreover, due to the limited supply of materials, it is difficult to meet the needs of large-area rapid laying. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a feather-shaped mechanical sand barrier and method, which achieves uniform soil penetration depth, precise control of inclination angle and porosity through simple standardized prefabricated component design, and significantly improves the wind erosion resistance and long-term stability of the mechanical sand barrier.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a feather-arrow type mechanical sand barrier, which includes sand barrier nails, sand barrier feathers, and striking caps; the sand barrier feathers are connected to the sand barrier nails and are away from the nail tips at the lower end of the sand barrier nails, and the sand barrier feathers are symmetrically and parallelly distributed on both sides of the sand barrier nails along the axis of the sand barrier nails; the striking caps are connected to the upper end of the sand barrier nails to form feather-arrow sand barrier nails; the lower ends of multiple feather-arrow sand barrier nails are driven into the sand and soil, and two adjacent sand barrier feathers contact each other to form a sand barrier band or sand barrier grid.

[0006] The sand barrier feather includes feathers and an outer frame; the outer frame is fixedly connected to the sand barrier nails, and multiple feathers are located inside the outer frame and fixedly connected to the outer frame and the sand barrier nails.

[0007] The barbs of the sand barrier feathers are inclined toward the tip of the sand barrier nail, and the barbs located on both sides of the sand barrier nail are symmetrical and swallowtail-shaped.

[0008] The barbs of the sand barrier feathers are laterally symmetrical and perpendicular to both sides of the sand barrier nails.

[0009] The sand barrier nails, sand barrier feathers, and striking caps are integrally molded from polyethylene, nylon, or unplasticized polyvinyl chloride materials.

[0010] The feathered arrow sand barrier nail also includes a threaded tube, which is threadedly connected to the threaded section of the sand barrier nail. The sand barrier feather is connected to the threaded tube, and the striking cap is sleeved with the sand barrier nail.

[0011] The outer wall of the threaded pipe is provided with clamping grooves on both sides, and the sand barrier feathers are clamped by the clamping grooves.

[0012] The sand barrier feathers are made of bamboo poles, bamboo strips or tree branches and are connected to the threaded tube to form an assembly structure.

[0013] The barbs of the sand barrier feathers are made of rice straw, reeds or stalks.

[0014] The construction method for the arrow-type mechanical sand barrier, as described above, includes the following steps: S1, forming a sand barrier belt: using a hammer to strike the striking cap of the feathered arrow sand barrier nail, driving the sand barrier nail into the sand. Multiple feathered arrow sand barrier nails are located on the same straight line to form a sand barrier belt; in this step, the lower side of the outer frame of the sand barrier feather is in contact with the ground surface, and the sides of two adjacent outer frames are in contact with each other. S2, based on S1, has multiple sand barrier zones intersecting to form a closed sand barrier grid; In S1, the tilt angle of the feathered sand barrier nail is adjusted according to the windward requirements; the porosity of the sand barrier feather is selected according to the wind force.

[0015] The main beneficial effects of this invention are as follows: It has a simple structure, is easy to mass-produce, and has low cost.

[0016] Installation is quick and easy, and the standard accuracy is easy to control during construction.

[0017] During production and processing, sand barrier feathers with the corresponding porosity are produced according to specifications to better leverage the wind-permeable and sand-blocking effectiveness of the sand barriers.

[0018] It is highly adaptable and can be adapted to different wind speeds, sand particle sizes and surface conditions.

[0019] It has a stable structure and a reliable service life.

[0029] like Figures 1-7 In this invention, a feather-arrow type mechanical sand barrier is provided, comprising a sand barrier nail 1, sand barrier feathers 2, and a striking cap 3. The sand barrier feathers 2 are connected to the sand barrier nail 1 and are located away from the nail tip at the lower end of the sand barrier nail 1. The sand barrier feathers 2 are symmetrically and parallelly distributed on both sides of the sand barrier nail 1 along the axial direction of the sand barrier nail 1. The striking cap 3 is connected to the upper end of the sand barrier nail 1 to form a feather-arrow sand barrier nail. The lower ends of multiple feather-arrow sand barrier nails are driven into the sand and two adjacent sand barrier feathers 2 are in contact with each other to form a sand barrier band or sand barrier grid.

[0030] The sand barrier feather 2 includes feathers 21 and an outer frame 22; the outer frame 22 is fixedly connected to the sand barrier nail 1, and multiple feathers 21 are located inside the outer frame 22 and fixedly connected to the outer frame 22 and the sand barrier nail 1.

[0031] The vanes 21 of the sand barrier feather 2 are inclined toward the tip of the sand barrier nail 1, and the vanes 21 located on both sides of the sand barrier nail 1 are symmetrical and swallowtail-shaped.

[0032] The vanes 21 of the sand barrier feather 2 are laterally symmetrical and perpendicular to both sides of the sand barrier nail 1.

[0033] The sand barrier nail 1, sand barrier feather 2, and striking cap 3 are integrally molded from polyethylene, nylon, or unplasticized polyvinyl chloride material.

[0034] The arrow-shaped sand barrier nail also includes a threaded tube 4, which is threadedly connected to the threaded section 11 of the sand barrier nail 1. The sand barrier feather 2 is connected to the threaded tube 4, and the striking cap 3 is sleeved with the sand barrier nail 1.

[0035] The outer wall of the threaded pipe 4 is provided with clamping grooves 41 on both sides, and the sand barrier feather 2 is clamped by the clamping grooves 41.

[0036] The sand barrier feathers 2 are made of bamboo poles, bamboo strips or branches and are connected to the threaded tube 4 to form an assembly structure.

[0037] The barbs 21 of the sand barrier feather 2 are made of rice straw, reeds or stalks.

[0038] Example 1, Preparation of one-piece molded arrow sand barrier nails: 1. Sand barrier nail 1, sand barrier feather 2 and striking cap 3 are integrally injection molded from polyethylene, nylon or unplasticized polyvinyl chloride material.

[0039] The width of the Sand Barrier Feather 2 is matched with different specifications according to wind force and wind speed.

[0040] The porosity of Sand Barrier 2 is matched with different specifications according to the requirements of sand blocking and fixation.

[0041] It facilitates mass production.

[0042] In Example 1, if the barbs 21 of the sand barrier feather 2 are laterally symmetrical and perpendicular to both sides of the sand barrier nail, its porosity can also be controlled by using bamboo poles, bamboo strips or branches in combination with straw, reeds or stalks.

[0043] Example 2, Preparation of arrow-shaped sand barrier nails for assembly structure. 1. Sand barrier nail 1 and striking cap 3 are integrally molded from polyethylene, nylon or unplasticized polyvinyl chloride material, and the sand barrier nail 1 is provided with threaded section 11; Sand barrier feather 2 and threaded tube 4 are integrally molded from polyethylene, nylon or unplasticized polyvinyl chloride material, or molded separately; Among them, the sand barrier feather 2 can also be made of bamboo poles, bamboo strips or branches; or the outer frame 22 can be made of bamboo poles, bamboo strips or branches and then woven together with straw, reeds or stalks to form the sand barrier feather 2. The width and porosity of the sand barrier feather 2 are prepared into different models and specifications.

[0044] During assembly: The sand barrier feather 2 and the threaded tube 4 are integrally formed. The width and porosity of the sand barrier feather 2 are selected according to the wind force and wind speed to match the appropriate model. Then, the threaded tube 4 is threadedly engaged with the threaded section 11 of the sand barrier nail 1.

[0045] 2. The sand barrier feather 2 and the threaded tube 4 are formed separately. First, the threaded tube 4 is threaded to the threaded section 11 of the sand barrier nail 1. Then, the sand barrier feather 2 with a suitable porosity is selected according to the wind force and wind speed and inserted into the clamping groove 41 of the threaded tube 4.

[0046] Its assembly is flexible and interchangeable, making it easy to mass-produce.

[0047] 2. Sand barrier nail 1 and striking cap 3 are integrally molded from polyethylene, nylon or unplasticized polyvinyl chloride material; or, striking cap 3 is separately molded from polyethylene, nylon or unplasticized polyvinyl chloride material.

[0048] During assembly: The sand barrier nail 1 and the striking cap 3 are integrally molded structures. The sand barrier feather 2 is made of bamboo poles, bamboo strips or branches, or is made of straw, reeds or stalks and is bound together with the sand barrier nail 1. When weaving and binding, the width and porosity of the sand barrier feather 2 are controlled according to the wind force and wind speed.

[0049] 2. The striking cap 3 is formed separately. The sand barrier nail 1 is made of bamboo poles, bamboo strips or branches. The sand barrier feather 2 is made of bamboo poles, bamboo strips or branches, or is woven with straw, reeds or stalks, and is bound together with the sand barrier nail 1. When weaving and binding, the width and porosity of the sand barrier feather 2 are controlled according to the wind force and wind speed. The striking cap 3 is fitted on the upper end of the sand barrier nail 1.

[0050] Example 3, The construction method for the arrow-type mechanical sand barrier, as described above, includes the following steps: S1, forming a sand barrier belt, using a hammer to strike the striking cap 3 of the feather arrow sand barrier nail, driving the sand barrier nail 1 into the sand, multiple feather arrow sand barrier nails are located on the same straight line to form a sand barrier belt; in this step, the lower side of the outer frame 22 of the sand barrier feather 2 is in contact with the ground surface, and the sides of two adjacent outer frames 22 are in contact with each other. S2, based on S1, has multiple sand barrier zones intersecting to form a closed sand barrier grid; In S1, the tilt angle of the arrow sand barrier nail is adjusted according to the windward requirements; the porosity of the sand barrier feather 2 is selected according to the wind force.

[0051] Example 4, Sand barrier nails are approximately 50-60cm long and 2-3cm in diameter. They are made of high-strength chemical materials such as polyethylene, nylon, and UPVC, or can be made from natural materials such as straight bamboo poles, bamboo strips, or tree branches.

[0052] The sand barbs 2 are symmetrically distributed in the upper 20cm area of ​​the sand barrier nail 1. The width is matched according to the wind force and speed, with a single-sided width of 10~15cm. The material can be weather-resistant chemical materials such as polyethylene, nylon, and UPVC. They are integrally molded with the sand barrier nail 1 to ensure that the barbs are firmly connected to the sand barrier nail 1.

[0053] Alternatively, natural materials such as straw and reed stalks can be woven and processed to be stably clamped in the upper 20cm area of ​​the sand barrier nail 1; the porosity of the sand barrier feather 2 is controlled according to the requirements of sand blocking and fixation, between 10% and 25%, so as to take into account both the functions of ventilation and deceleration and effective sand blocking.

[0054] The striking cap 3 is located at the top of the sand barrier nail 1 and is disc-shaped. It is 2-3cm away from the top of the sand barrier feather 2, which makes it easy to use simple tools to vertically hammer the sand barrier nail 1 into the sand layer during construction without damaging the sand barrier feather 2, ensuring that the penetration depth of the feather-shaped sand barrier is uniformly 30±2cm.

[0055] When using natural materials such as bamboo poles, bamboo strips or branches, the striking cap 3 adopts a sleeve structure and is fitted onto the top of the sand barrier nail 1.

[0056] By arranging multiple individual arrow-shaped sand-fixing nails at standard intervals, a continuous sand-fixing grid is formed, effectively improving the overall windbreak and sand-fixing efficiency.
