Description

Technical Field

[0001] This invention belongs to the field of civil engineering, specifically relating to a portable geotextile binding device for slope protection and its usage method. Background Technology

[0002] Geotextile, also known as geotextile fabric, is a permeable geosynthetic material made of synthetic fibers through needle punching or weaving. Geotextile is one of the new geosynthetic materials. The finished product is cloth-like, generally 4-6 meters wide and 50-100 meters long. Geotextile is divided into woven geotextile and non-woven filament geotextile. It has excellent filtration, drainage, isolation, reinforcement, seepage prevention and protection functions. It is lightweight, has high tensile strength, good permeability, high temperature resistance, freeze resistance, aging resistance and corrosion resistance. It can be used as a filter layer for dams, canals, coasts, concrete slopes, retaining walls, etc. While preventing soil particles from passing through, it allows water or gas to pass through freely. When used on embankments, it can prevent the erosion of wind, waves and rain, and is used for bank protection, bottom protection and prevention of soil erosion.

[0003] According to the search, the invention disclosed in CN103215940B provides an overlapping device for the upper layer of geotextile of a composite geomembrane, including a bottom plate and a top plate. The top plate is located above the bottom plate. One end of the upper steel strip is connected to the top plate, and the other end is connected to one end of the middle steel strip. The other end of the middle steel strip is connected to one end of the lower steel strip, and the other end of the lower steel strip is connected to the bottom plate. A needle-out device is installed at the bottom of the top plate, and a needle-receiving plate adapted to the position of the needle-out device is provided on the bottom plate.

[0004] However, manual binding and moving are still required, and workers have to bend over for long periods of time, which puts a heavy burden on them.

[0005] When the laying area is large, stitching is required to ensure its function. However, traditional manual stitching of geotextiles is inefficient and labor-intensive. Summary of the Invention

[0006] To solve the above-mentioned technical problems, the inventors derived the technical solution of the present invention through practice and summarization. The present invention discloses a portable geotextile binding device for slope protection, including a support device and a working device; the support device includes an upper telescopic rod and a lower fixed rod; the working device includes a sewing part and a column located at the end of the fixed rod of the support device that cooperates with a spring, and limit plates are provided at both ends of the column; the sewing part is installed next to the column, and a foot pedal is provided on one side;

[0007] The suture section includes a fixed rotating wheel located in the lower middle part of the fixed rod, around which the suture thread is wound, which cooperates with an insertion needle located on one side of the end of the fixed rod; the outer surface of the telescopic rod is fitted to the inner surface of the fixed rod, and both the fixed rod and the telescopic rod have limit holes; the limit holes are fitted with fixing heads. The use of different limit holes allows for adaptation to people of different heights, improving applicability.

[0008] The working device includes a column located at the end of the support device and fitted with a spring, with limit plates at both ends; a sewing part is installed on one side of the column and a pedal is installed on the other side; the pedal avoids the problem of long bending over required for traditional manual sewing, thus reducing the burden on construction workers.

[0009] The suture section includes a fixed rotating wheel located in the lower part of the fixed rod, around which the suture thread is wound. The suture thread is a barbed suture thread. It works in conjunction with a soil-inserting needle located on one side of the end of the fixed rod. The use of barbed suture thread and single-sided needle insertion avoids the problem of traditional sutures requiring double-sided needle insertion and high labor intensity. The fixed rotating wheel and the soil-inserting needle are close together, which prevents the suture thread from getting tangled together during suture.

[0010] Furthermore, the telescopic section away from the ground is equipped with a rotatable support handle; this helps construction workers to better hold the binding device steady, while also accommodating workers with different hand preferences.

[0011] Furthermore, the support handles are covered with rubber sleeves at both ends to help construction workers better hold the binding device steady.

[0012] Furthermore, the soil-penetrating needle is a hollow structure with a lead tube and a lead hole at the top; the lead hole helps construction workers to better thread the needle in the construction environment.

[0013] Furthermore, the fixed roller is fitted to the lower end of the fixed rod and is completely inserted through the fixed shaft; the suture thread can be replenished more quickly by replacing the roller, while the fixed shaft is used to tighten the roller and prevent it from falling off during operation.

[0014] Furthermore, the lower limit plate located near the ground end of the fixed rod and the column are fixed by threads; this facilitates timely replacement in case of damage and extends the service life of the binder.

[0015] Furthermore, the column is equipped with a spring; the spring is removable; damaged parts can be replaced, extending its service life.

[0016] Furthermore, the sutured part is externally equipped with a shell, on which a fixed rotating wheel and a soil-inserting needle are fixed. The soil-inserting needle passes through the shell and is fixed with a limiting ring. The shell is snapped onto both sides of the column. The shell protects the internal barbed sutures from damage, and at the same time, the shell, rotating wheel, and soil-inserting needle are fixed together as one unit. The center point of the fixed rotating wheel is located on the extension line of the length direction of the soil-inserting needle. This shortens the distance that the barbed thread extends from the rotating wheel into the soil-inserting needle, avoids tangling and knotting, and allows for quick replacement, making it more convenient to use.

[0017] Furthermore, the outer shell is fitted with a snap-fit ​​connection to both ends of the fixed shaft; two sets of parallel sewing devices are set on both sides, which can sew two stitches at once, thus speeding up the process.

[0018] Furthermore, the outer shells can be assembled together on the same horizontal plane; two sets of horizontal sewing devices can be set up to double-stitch a single suture line, thereby enhancing the sewing effect.

[0019] The present invention also discloses a method for using the above-mentioned portable binding device for slope protection geotextiles, comprising the following steps:

[0020] Step 1: Lay the geotextile;

[0021] First, the geotextile is laid on the slope in overlapping sections;

[0022] Step 2: Adjust the binding device;

[0023] Before the sewing and binding work, the construction personnel adjust the height of the binding device according to their own height. By pressing the fixed head with both hands, the fixed head is retracted into the telescopic rod. The telescopic rod and telescopic joint are moved up and down, so that the fixed head slides along the inner wall. According to the individual's height and operating height, the fixed head is moved into the limiting hole and locked, reaching the operating height.

[0024] Step 3: Sew the geotextile together;

[0025] Construction workers and operators can use both hands to hold the rubber handles for overall control and to stabilize the binding device;

[0026] The pedal section is welded to the lower end of the rod. During use, the operator holds the handle and steps on the pedal with one foot to apply downward stress. During operation, the downward stress causes the spring to contract, which moves the upper limit plate downward, causing the entire binding device to work downward. As the binding device works downward, the insertion needle moves downward, bringing the barbed suture thread through the guide port into the guide tube. After passing through the geotextile, the spring rebounds, moving the entire binding device upward. The barbs on the barbed suture thread stick to the upper and lower layers of geotextile, and the barbed suture thread remains in the lower layer of geotextile due to the resistance of the barbs. The insertion needle is then pulled out by the elastic force.

[0027] Step 4: Repeat step 3 until the suturing is complete.

[0028] Compared with the prior art, the present invention can achieve the following technical effects:

[0029] The working device includes a sewing section and a column located at the end of the support device's fixing rod, which is fitted with a spring. Limit plates are installed at both ends of the column; the bottom limit plate is removable for easy replacement of parts. The sewing section is installed next to the column, and a pedal is located on the other side. The sewing section includes a fixed rotating wheel located in the lower middle part of the fixing rod, around which barbed sewing thread is wound. Using barbed sewing thread avoids the need for double-sided needle insertion required in traditional geotextile sewing; sewing can be completed with needle insertion on only one side. It is fitted with a soil-inserting needle located on one side of the fixing rod's end. The soil-inserting needle has a hollow structure with a thread guide opening at the top, facilitating the introduction of the barbed sewing thread into the needle during construction, improving work efficiency. Furthermore, a housing can be used to fix the wheel and soil-inserting needle, forming an integrated sewing device. This prevents the sewing thread from being exposed to the external environment and contaminating with mud and sand. Placing the soil-inserting needle and rotating wheel on the same axis shortens the distance the sewing thread needs to enter the needle, avoiding knotting problems. Multiple integrated sewing devices can also be installed on a single device, effectively improving efficiency.

[0030] The support device includes a fixed rod and a telescopic rod; both the fixed rod and the telescopic rod have limit holes, and the height of the device can be adjusted by selecting different limit holes to install the fixing head, thus improving its applicability.

[0031] By utilizing the elasticity of the spring and the cooperation of the pedal, workers can complete the sewing of geotextiles while standing, eliminating the need for prolonged squatting and bending over as in traditional sewing operations. This reduces the workload of construction workers and eliminates the need for double-sided needle insertion as in traditional sewing methods, thus reducing sewing time and increasing work efficiency.

Detailed Implementation

[0043] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the embodiments; it should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0044] The application principle of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0045] Example 1

[0046] A portable geotextile binding device for slope protection includes a support device and a working device; the support device includes a telescopic rod and a fixed rod; the top of the telescopic rod is provided with a rotatable handle, the surface of which is covered with a rubber sleeve; there is an upper telescopic rod and a lower fixed rod; the outer surface of the telescopic rod fits into the inner surface of the fixed rod and has a limiting hole; the limiting hole is fitted with a fixing head to fix the position of the telescopic rod.

[0047] The working device includes a suturing section and a column located at the end of the support device's fixing rod, which is fitted with a spring. Limiting plates are provided at both ends of the column. The lower limiting plate near the ground end of the fixing rod is threaded and fixed to the column. A spring is installed inside the column. The suturing section is installed next to the column, and a pedal is provided on one side. The suturing section includes a fixed rotating wheel located in the lower middle part of the fixing rod, which is fitted with a soil-inserting needle located on one side of the end of the fixing rod. The fixed rotating wheel is installed at the lower end of the fixing rod, which is completely through a fixing shaft. The fixed rotating wheel is wrapped with barbed sutures. The soil-inserting needle is a hollow structure with a guide tube inside. A guide hole is opened at the top of the needle. The barbed sutures enter the guide tube through the guide hole and extend from the lower end of the soil-inserting needle.

[0048] Example 2

[0049] Based on Example 1, this example is basically the same as Example 1, but with the following differences: Figure 7 As shown; the suture part is replaced with an integrated suture part. The integrated suture part is covered by an outer shell and has a rotating wheel inside. The insertion needle passes through the limiting ring and is fixed to the lower end of the outer shell, and is on the same central axis as the rotating wheel. This prevents the barbed suture line from being too large and hooking other items. At the same time, it is fixed to both ends of the fixed shaft with buckles and is fully inserted into the fixed shaft for secure fastening. This allows one or more suture parts to be installed on one stapler. At this time, repeating embodiment 1 can achieve the completion of two parallel suture lines at one time, further improving work efficiency.

[0050] Example 3

[0051] Based on Example 2, this example is basically the same as Example 2, but with the following differences: Figure 8 As shown; the outer shell is assembled in parallel, with two sets of rotating wheels and soil-inserting needles installed inside. The buckle is fixed to one end of the fixed shaft, and the other end of the fixed shaft is tightened. By repeating Example 1, two suture lines can be interwoven and stitched to form a dense suture line, achieving a better suturing effect.

[0052] Example 4

[0053] like Figure 1-5 As shown in the embodiment of the present invention, a method for using a portable geotextile binding device for slope protection is provided.

[0054] Step 1: First, lay the geotextile on the slope with overlapping sections;

[0055] Step 2: Before the sewing and binding work, the construction personnel adjust the height of the binding device according to their own height. By pressing the fixed head with both hands, the fixed head is retracted into the telescopic rod. The telescopic rod and telescopic joint are moved up and down to make the fixed head slide along the inner wall. According to the individual's height and operating height, the fixed head is moved into the limiting hole and locked, reaching the operating height.

[0056] Step 3: Construction workers and operators can maintain overall control by holding the rubber handrails with both hands;

[0057] Step 4: The pedal part is welded to the lower end of the pole. When in use, the operator holds the handrail and steps on the pedal with one foot to apply downward stress.

[0058] Step 5: Spring pressure device section. During operation, the stress is downward, the spring is compressed, which drives the upper limit plate to move downward, so that the entire binding device does work downward.

[0059] Step 6: During operation, as the binding device moves downward, the insertion needle moves downward, driving the barbed suture thread through the guide hole into the guide tube; it passes through the geotextile, the spring rebounds, and drives the binding device upward. The barbs on the main body of the barbed suture thread get stuck between the upper and lower layers of geotextile. The barbed suture thread remains in the lower layer of geotextile due to the resistance of the barbs. The insertion needle is pulled out under the action of the elastic force. Repeat the above operation to complete the binding and sewing.

[0060] Example 5

[0061] like Figure 6 As shown in the embodiment of the present invention, a method for using a portable geotextile binding device for slope protection is provided.

[0062] After the work is completed, the sewn part can be removed to avoid damage to the needle. At the same time, the lower limit plate and spring can be removed and replaced with a solid steel needle for use as a level indicator.

[0063] Working principle: During operation, the worker holds the handrails with both hands and places one foot on the pedal to apply downward stress; the spring contracts under pressure, causing the upper limit plate to move downward, thus causing the entire binding device to perform downward work; as the binding device performs downward work, the insertion needle moves downward, bringing the barbed suture thread through the guide port into the guide tube; after passing through the geotextile, the spring rebounds, causing the entire binding device to move upward, and the barbs on the main body of the barbed suture thread get stuck between the upper and lower layers of geotextile. The barbed suture thread remains in the lower layer of geotextile due to the resistance of the barbs, and the insertion needle is pulled out under the action of the elastic force, completing one stitch.

[0064] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.

[0065] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
