Technical Field

[0001] This utility model relates to the field of geotextile fixing technology, and in particular to a geotextile fixing device for roadbed construction. 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. Geotextile is divided into woven geotextile and non-woven filament geotextile. In the process of engineering construction, geotextile can be used to cover the exposed loess, which plays a role in dust prevention and prevents the loess from being blown away by strong winds and affecting the environment. When laying geotextile, geotextile fixing devices are required to fix the geotextile.

[0003] In the process of fixing geotextiles, the traditional fixing method is a single fixing method, which has a relatively general fixing effect. At the same time, during the fixing process, some geotextiles are long and will accumulate at the fixing position, which is not convenient to organize and fix. Therefore, a geotextile fixing device for roadbed construction is proposed. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example: Refer to Figure 1-4 A geotextile fixing device for roadbed construction includes a bottom fixing block 1, a top fixing block 2 mounted on top of the bottom fixing block 1 via a threaded clamping assembly, a clamping and positioning assembly between the bottom fixing block 1 and the top fixing block 2, a winding groove 8 at the bottom of the bottom fixing block 1, a side support rod 9 fixedly mounted on the side of the bottom fixing block 1, a winding shaft 10 rotatably mounted on the side support rod 9, a winding positioning assembly between the end of the winding shaft 10 and the side support rod 9, and multiple fixing rods 18 fixedly mounted at the bottom of the bottom fixing block 1. A positioning through hole 11 is provided on the winding shaft 10. The bottom of the top fixing block 2 is provided with a top groove 12, which is located above the winding groove 8. During the roadbed construction, geotextile is used to prevent dust. After the geotextile is laid, it needs to be positioned. The bottom fixing block 1 with the fixing rod 18 is fixedly installed on the ground. Then, one side of the geotextile is passed through the positioning hole 11, and then the winding shaft 10 is rotated. By rotating, the geotextile can be wound around the winding shaft 10 for winding and fixing. By winding, a longer geotextile can be wound up, avoiding the problem of long edges piling up and being difficult to fix.

[0022] Specifically, the winding positioning assembly includes a rotating disk 13 fixedly installed at the end of the winding shaft 10. Two positioning posts 14 are movably installed on the rotating disk 13. Multiple positioning slots 17 are opened on one side of the side support rod 9. One end of the two positioning posts 14 extends into the corresponding two positioning slots 17. An end block 15 is fixedly installed at one end of the two positioning posts 14. A return spring 16 is fixedly installed between the end block 15 and the rotating disk 13. The number of positioning slots 17 is even. After winding, the end block 15 on the winding positioning assembly is released. Under the elastic force of the return spring 16, the positioning posts 14 can be driven to lock into the corresponding two positioning slots 17. The number of positioning slots 17 is at least 8. The geotextile can be fixed by positioning the position of the positioning posts 14.

[0023] Specifically, the threaded clamping assembly includes a threaded post 5 fixedly installed on the top of the bottom fixing block 1, the threaded post 5 movably passing through the top fixing block 2, a clamping nut 6 provided on the top of the top fixing block 2, the clamping nut 6 being threaded onto the threaded post 5, and multiple guide posts 7 fixedly installed on the top of the bottom fixing block 1, the multiple guide posts 7 respectively movably passing through the top fixing block 2. After winding up the excess geotextile, the worker rotates the clamping nut 6 on the threaded clamping assembly. After the clamping nut 6 rotates, it drives the top fixing block 2 to move downward. The provided guide posts 7 can limit the movement position of the top fixing block 2.

[0024] Specifically, the clamping and positioning component includes a bottom groove 3 on the bottom fixing block 1 and a top tooth 4 fixedly installed on the top fixing block 2. The top tooth 4 is set to correspond with the bottom groove 3. The top tooth 4 on the top fixing block 2 will be clamped on the bottom groove 3 to perform secondary clamping on the geotextile. Through double clamping, the geotextile can be stably fixed, avoiding the problem of the geotextile being blown away by the wind in strong wind weather.

[0025] In use: During roadbed construction, the geotextile with the fixing rod 18 is fixedly installed on the ground. One side of the geotextile is passed through the positioning hole 11, and then the winding shaft 10 is rotated to wind the geotextile around the winding shaft 10. By winding, a longer geotextile can be wound up, avoiding the problem of long edges piling up and being difficult to fix. After winding, the positioning post 14 is used to position the geotextile, which can fix the geotextile. After winding up the excess geotextile, the worker rotates the clamping nut 6 on the threaded clamping assembly, which moves the top fixing block 2 down. With the help of the top locking tooth 4 and the bottom locking groove 3, the geotextile is clamped a second time. Through double clamping, the geotextile can be stably fixed, avoiding the problem of the geotextile being blown away by the wind in strong winds. It is easy to use.
