[0002] During the pouring of flexible pipe encapsulated concrete, the pipe often floats due to its light material, especially for large diameter flexible pipes. The floating phenomenon is more obvious. The floating of the pipe will cause the pipe line shape and deviation to fail to meet the design and specification requirements, and the design flow rate of the water flow cannot be guaranteed, and even lead to reverse slope drainage, siltation, blockage and other problems in the pipe. Once the pipe floats, it is generally impossible to correct it. In severe cases, it can only be re-poured, causing huge energy and economic losses and affecting the construction progress.

[0023] The utility model discloses a fixing device for preventing lateral displacement of a flexible pipe. Figure 1-Figure 4 The fixing device for preventing the lateral movement of the flexible pipe comprises a cross bar, two supporting rods and a flexible pipe fixing rope, wherein both ends of the cross bar are fixed on the trench wall, one end of the two supporting rods are respectively arranged on both sides of the midpoint of the cross bar, and both ends of the pipe fixing rope are respectively fixed on the ends of the two supporting rods away from the cross bar and pressed against the pipe, thereby enhancing the performance of the flexible pipe in resisting the impact force and buoyancy of concrete pouring during the concrete encapsulation construction process, improving the construction quality of the pipe network project, being easy to operate and having outstanding effects.

[0024] In this embodiment, the cross bar 1 is evenly provided with a plurality of first hinge parts 12 for hingedly connecting the support rods 2 along its length direction, so that the support rods 2 can be hingedly installed at different positions on the cross bar 1, and flexible pipes of different diameters can be fixed by replacing different hinge points.

[0025] In this embodiment, the end of the support rod 2 away from the cross bar 1 is provided with a clamp 5 for fixing the bottom end of the pipe fixing rope 3. The pipe fixing rope 3 is installed by clamping and fixing one end of the pipe fixing rope 3 through the clamp 5 on one of the support rods 2, and the other end of the pipe fixing rope 3 is passed over the top of the pipe and pressed against the pipe, and the pipe fixing rope 5 is clamped and fixed by the clamp 5 on the other support rod 2 to fix the pipe.

[0026] In this embodiment, the clamp 5 includes a fixing plate 51, a clamp 52 and a fixing bolt 53 arranged at the end of the support rod 2. The fixing plate 51 and the clamp 52 are connected by the fixing bolt 53. Two fixing bolts 53 pass through the two ends of the clamp 52, and a nut is installed through one end of the fixing plate 51. The end of the pipeline fixing cable 3 passes between the fixing plate 51 and the clamp 52, and the clamp 52 is moved to contact the pipeline fixing cable 3.
