Description

Technical Field

[0001] This application relates to the technical field of bridge pile foundations, and particularly to a positioning device for steel sleeves of bridge pile foundations applicable to karst areas. Background Art

[0002] In the construction of bridge pile foundations in karst areas, the accurate positioning and installation of steel sleeves are key links to ensure the construction quality and stability of pile foundations. However, there are some obvious drawbacks in the existing technical solutions for the positioning devices of steel sleeves of bridge pile foundations in karst areas. First of all, traditional positioning devices often rely on manual marking and simple positioning tools. This method is not only inefficient but also easily affected by human errors, resulting in inaccurate positioning. Especially in karst areas, due to the complexity of geological conditions, it is more difficult to ensure the accurate installation of steel sleeves by traditional positioning methods. Secondly, due to geological phenomena such as karst caves and fissures in karst areas, higher requirements are put forward for the positioning and installation of steel sleeves, and the existing positioning tools are too simple in structure and often unable to effectively cope with these challenges.

[0018] The following is a further detailed description of the present application in conjunction with the attached Figures 1-3 drawings.

[0019] An embodiment of the present application discloses a positioning device for a steel sleeve of a bridge pile foundation applicable to a karst area. Refer toFigure 1 , including a steel sleeve matrix 1, on the outer surface of the steel sleeve matrix 1, a number of resistance grooves 2 are evenly distributed, which can enhance the frictional resistance and improve the installation stability. An installation groove 12 is provided inside the steel sleeve matrix 1 to facilitate the mating connection with the bridge pile foundation. On the outer wall at the top end of the steel sleeve matrix 1, a number of reinforcing top blocks 7 are fixedly installed at equal intervals, and on the outer wall at the bottom end of the steel sleeve matrix 1, a number of reinforcing bottom blocks 6 are fixedly installed at equal intervals, which can support both ends of the steel sleeve matrix 1, improve the strength of the edge part, and provide a stable supporting force.

[0020] Combined with Figure 2 As shown, a fixing block 8 is integrally welded to the outer wall of the reinforcing bottom block 6. A threaded rod 9 that is adapted is threadedly connected inside the fixing block 8. One end of the threaded rod 9 extends to the bottom of the fixing block 8 and is movably connected to a positioning pointed cone 10. By rotating the threaded rod 9, the positioning pointed cone 10 can be pushed downward, and it can be inserted into the ground soil or the slot hole of the connecting piece for positioning, and it can be operated and used according to the actual situation.

[0021] Combined with Figure 3 As shown, a number of first reinforcing support rods 3 and second reinforcing support rods 4 are respectively fixedly arranged along the circumference on the outer walls at both ends of the steel sleeve matrix 1. The first reinforcing support rods 3 and the second reinforcing support rods 4 can support both ends of the steel sleeve matrix 1, which is convenient for connection and fixation and has a good positioning effect. A central hole 13 is provided at the center of the outer surface of the steel sleeve matrix 1, and the steel sleeve matrix 1 and the bridge pile foundation can be further positioned through fasteners;

[0022] One ends of the first reinforcing support rods 3 and the second reinforcing support rods 4 that are far away from each other are integrally fixed with positioning blocks 5. A number of connecting holes 11 are evenly distributed inside the positioning blocks 5. Through the positioning blocks 5 at both ends, connection and positioning with the inner connecting piece of the bridge pile foundation can be achieved, further improving the stability of the bridge pile foundation.

[0023] The implementation principle of a positioning device for a steel sleeve of a bridge pile foundation applicable to karst areas in an embodiment of the present application is as follows: During use, the steel sleeve matrix 1 is installed outside the bridge pile foundation. At this time, the bridge pile foundation is located in the installation groove 12. After adjusting the steel sleeve matrix 1 to a suitable position outside the bridge pile foundation, the positioning blocks 5 at both ends and the connecting components outside the bridge pile foundation are fixed by bolts passing through the connection holes 11. Then, the two ends of the steel sleeve matrix 1 can be supported by the first reinforcing support rod 3 and the second reinforcing support rod 4, and a good positioning and supporting effect can be achieved. The setting of the reinforcing bottom block 6 and the reinforcing top block 7 can strengthen the two ends of the steel sleeve matrix 1 to prevent cracking. Then, the steel sleeve matrix 1 and the bridge pile foundation are further positioned by external fasteners or bolts passing through the central hole 13, which can effectively prevent the steel sleeve matrix 1 from falling off. Then, rotate the threaded rod 9 to make it move downward to push the positioning pointed cone 10 into the soil or the corresponding connecting piece groove of the bridge pile foundation for positioning, and the overall installation and positioning can be completed, further improving the stability of the bridge pile foundation and reducing the influence of wind and rain.
