Description

Technical Field

[0001] The utility model relates to the technical field of roadbed construction, in particular to a geotextile fixing device used for roadbed construction. Background Art

[0002] Saline soil is widely distributed. Highways built in saline soil areas are prone to road frost heave and muddying, which can cause road surface collapse and shorten the service life of the road. Therefore, the roadbed is often constructed by replacing the fill soil, and geotextiles are laid between the fill soil and the saline soil to isolate them and prevent saline soil diseases.

[0003] The geotextile is laid over a large area. If strong winds are encountered during the construction process, the geotextile will be blown away or overturned, requiring continuous manual work to sort it out. Otherwise, the geotextile will not be laid tightly or wrinkles will appear, affecting the isolation effect and posing the risk of salt swelling or melting settlement of the roadbed.

It should be understood that the specific embodiments described here are part of the embodiments of the utility model, not all of the embodiments, and are only used to explain the embodiments of the utility model, and are not used to limit the embodiments of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-Figure 4 The utility model provides a technical solution: a geotextile fixing device for roadbed construction, comprising: a fixing cylinder 1, a rotating rod 2, a fixing plate 12 and a pressing plate 20. The lower end of the rotating rod 2 is inserted into the fixing cylinder 1 and is rotatably connected through a bearing. A driving block 3 is fixedly installed on the upper end of the rotating rod 2. The driving block 3 is in an equilateral hexagonal shape, which is convenient for connecting with an inner hexagonal wrench. The driving rotating rod 2 is driven to rotate at the inner end of the fixing cylinder 1. A pointed cone is fixedly installed at the lower end of the fixing cylinder 1 to facilitate inserting the fixing cylinder 1 into the ground. A circular hole running through the upper and lower ends of the fixing plate 12 is opened at one end. The lower end of the fixing cylinder 1 passes through the circular hole and is inserted into the ground. The baffle 11 on the fixing cylinder 1 contacts the upper end of the fixing plate 12 to fix the fixing plate 12 on the ground. A rubber pad 22 is fixedly installed on the upper end of the fixing plate 12.

[0022] A threaded groove 4 is provided on the outer wall of the rotating rod 2, and the rotating rod 2 is threadedly connected with a threaded sleeve 9 through the threaded groove 4. Openings 5 ​​are symmetrically provided on the left and right sides of the lower end of the fixed cylinder 1. A rotating plate 6 is rotatably connected to the opening 5 through a telescopic rod 7. One end of the telescopic rod 7 is fixedly installed on the inner wall of the lower end of the rotating plate 6, and the telescopic rod 7 is rotatably connected to the side wall of the fixed cylinder 1 through a rotating shaft. A strip hole 8 is provided at the other end of the telescopic rod 7. Two ear blocks 10 are symmetrically fixedly installed on the outer wall of the threaded sleeve 9, and an axle pin is fixedly installed at one end of the ear block 10. The outer end of the axle pin passes through the strip hole 8, so that the other end of the telescopic rod 7 can slide and rotate on the ear block 10. By rotating the rotating rod 2, the threaded sleeve 9 can be driven to move on the outer wall of the rotating rod 2, thereby driving the telescopic rod 7 to move, open the rotating plate 6, and increase the grip of the fixed cylinder 1.

[0023] A column 13 is fixedly installed on one side of the upper end of the fixed plate 12, and two grooves 16 are symmetrically provided on the left and right sides of the lower end of the column 13. A spring 18 is fixedly installed on the inner end of the groove 16. A limit column 17 is slidably inserted into the groove 16. The inner end of the limit column 17 and one end of the spring 18 are fixedly connected. The limit column 17 can be moved into the groove 16 by compressing the spring 18. When the spring 18 is in a balanced state, one end of the limit column 17 is located on the outside of the groove 16.

[0024] The pressure plate 20 is slidably connected to the outer wall of the column 13 through the sliding sleeve 14. A connecting block 19 is fixedly installed at one end of the sliding sleeve 14. The other end of the connecting block 19 is fixedly connected to the outer end of the pressure plate 20. A plurality of limiting cones 21 are evenly fixedly installed on the lower end of the pressure plate 20. The sliding sleeve 14 is slidably sleeved on the upper end of the column 13. A slope 15 is provided at the lower end of the sliding sleeve 14. By pressing the sliding sleeve 14 downward with force, the slope 15 of the sliding sleeve 14 contacts the outer end of the limiting column 17 and pushes the limiting column 17 inward. After the limiting column 17 passes over the sliding sleeve 14, the limiting column 17 is restored under the reaction force of the spring 18. The limiting column 17 limits the movement of the sliding sleeve 14. At this time, the limiting cone 21 at the lower end of the pressure plate 20 contacts the upper side wall of the rubber pad 22.

[0025] In actual use, first fix the fixing plate 12 on the ground with the fixing tube 1, place the geotextile on the upper end of the rubber pad 22, and then press down the sleeve 14 with force. The slope 15 of the sleeve 14 contacts the outer end of the limit column 17, and push the limit column 17 inward. After the limit column 17 passes over the sleeve 14, the limit column 17 is restored under the reaction force of the spring 18. The limit column 17 limits the movement on the sleeve 14. At this time, the limit cone 21 at the lower end of the pressure plate 20 presses the geotextile tightly against the upper end of the rubber pad 22 to fix the geotextile.
