They have the advantages of light weight, convenient construction process, and no need to waste raw materials such as sand and stone. Flexible pipes are easy to deform, so they are often fixed with cast-in-place 180° concrete foundations. It is precisely because of the light weight of flexible pipes that they are prone to displacement during the foundation pouring process. Once the flexible pipes are displaced during the construction process, it may cause the entire drainage system to fail to meet the design requirements or even fail. Therefore, how to fix the flexible pipes during the construction process for foundation pouring construction has become the key to the quality of flexible pipe construction.

DETAILED DESCRIPTION

[0023] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0024] like Figure 1 , Figure 2 As shown, the anti-floating fixed structure of the flexible pipeline of the utility model, the lower half surface of the pipeline 2 is embedded in the cast-in-place concrete foundation 3. In order to prevent the pipeline from floating left and right and floating up during the pouring and tamping process of the cast-in-place concrete foundation 3, the fixed structure includes a plurality of fixing mechanisms 1 arranged at intervals along the pipeline 2. The specific intervals between the fixing mechanisms 1 are determined by experiments according to the actual situation to obtain a suitable value to ensure that all parts of the pipeline do not move. The fixing mechanism 1 includes a crossbar 11, a left counterweight 13, a right counterweight 14, and an arc-shaped pressing plate 12 arranged on the upper half surface of the pipeline 2 and cooperating with the upper half surface of the fixed pipeline 2 to prevent the pipeline 2 from floating up and moving left and right. The left counterweight 13 and the right counterweight 14 are respectively arranged on the ground on both sides of the pipeline 2, and the crossbar 11 is arranged above the pipeline 2, and one end is inserted into the fixed left counterweight 13, and the other end is inserted into the fixed right counterweight 14. The pressing plate 12 is connected to the crossbar 11, that is, the pressing plate 12 is installed on the crossbar 11. The left counterweight 13 and the right counterweight 14 can be made of concrete segments or iron segments.

[0025] The flexible pipe anti-floating fixing structure of the utility model adopts the method of setting an arc-shaped pressure plate 12 on the upper surface of the pipe for fixing, so as to prevent the pipe from floating up and shifting left and right during the foundation construction process, and the pressure plate 12 is fixed by the horizontal bar 11 on the left counterweight block 13 and the right counterweight block 14 which are inserted and fixed on the ground on both sides of the pipe 2. The left counterweight block 13 and the right counterweight block 14 provide sufficient gravity for the pressure plate 12 to resist the buoyancy generated when pouring concrete, and there is no need to drive wooden piles, and there is no risk of foundation pit instability and collapse. The whole anti-floating fixing structure is easy to install, with high construction efficiency, and is safe and reliable.

[0026] The pressing plate 12 can be a whole piece or divided into multiple sections. When the pressing plate 12 is a whole piece, it is arranged just above the upper surface of the pipeline. In the embodiment of the utility model, the pressing plate 12 is divided into two sections and is respectively arranged on both sides of the upper surface of the pipeline 2.

[0027] Each section of the pressure plate 12 can be fixed on the cross bar 11 by welding. In the embodiment of the utility model, the fixing mechanism 1 also includes a first vertical rod 15 and a second vertical rod 16. In the pressure plate 12, one section is installed at the lower end of the first vertical rod 15, and the other section is installed at the lower end of the second vertical rod 16. The first vertical rod 15 and the second vertical rod 16 are respectively connected to the cross bar 11 by fasteners 17, specifically right-angle fasteners. Compared with the method of fixing on the cross bar by welding, the above structure can move the first vertical rod 15 and the second vertical rod 16 vertically and along the cross bar 11 by loosening the fasteners 17, so as to facilitate the adjustment of the height of the two sections of the pressure plate 12 and the distance between them according to the actual position and inner diameter of the pipeline, so that it is in a more suitable position to better fix the pipeline, which is more convenient to use and more practical.

[0028] In the above structure, the pressing plate 12 can be installed at the lower end of the corresponding vertical rod in a detachable connection mode or a non-detachable connection mode. Among them, the detachable connection mode can be bolt connection, clamping, plug-in connection, etc., and the non-detachable connection can be welding. In order to facilitate and better fix the pipeline, in the utility model, preferably, in the pressing plate 12, one section is detachably connected to the first vertical rod 15, and the other section is detachably connected to the second vertical rod 16. In this way, the arc-shaped pressing plate 12 adapted to the size of the pipeline can be replaced and installed to better force the pipeline and fix it better.

[0029] Each section of the pressing plate 12 can be fixedly mounted at the lower end of the corresponding vertical rod. Figure 3 As shown, the lower ends of the first vertical rod 15 and the second vertical rod 16 are both provided with a universal ball 19 that rotates therewith, and the bottom of the universal ball 19 is provided with a downwardly extending pressure plate connecting rod 20; in the pressure plate 12, one section is connected to the first vertical rod 15 through the pressure plate connecting rod 20 provided at the lower end of the first vertical rod 15, and the other section is connected to the second vertical rod 16 through the pressure plate connecting rod 20 provided at the lower end of the second vertical rod 16. That is, one section of the pressure plate is installed on the pressure plate connecting rod 20 at the lower end of the first vertical rod 15, and the other end is installed on the pressure plate connecting rod 20 at the lower end of the first vertical rod 15. Compared with the method of fixing the pressure plate section on the vertical rod, the above structure is installed on the pressure plate connecting rod of the corresponding vertical rod, and the pressure plate connecting rod is installed on the universal ball that rotates with the lower end of the corresponding vertical rod. In this way, each pressure plate section can rotate in all directions through the universal ball. In this way, when installing the vertical rod, each pressure plate section can adjust its position adaptively to make it fit better on the upper surface of the pipe, which reduces the horizontality of the cross bar and the verticality of the vertical rod when installing the fixed structure, making it more convenient to install the fixed structure. During installation, after the pressure plate is adjusted into place by itself, the vertical rod can be locked and fixed on the cross bar by fasteners.

[0030] During the foundation construction process, the pipeline will exert a lateral force on the pressure plate 12. If the first vertical rod 15 and the second vertical rod 16 are only fixed by the fasteners connected to the cross bar 11, the stability of the first vertical rod 15 and the second vertical rod 16 is poor, and the force may deflect, thereby causing the pipeline to float or deflect. For this reason, in the utility model, the fixing mechanism 1 also includes a reinforcing connecting rod 18, one end of which is detachably connected to the first vertical rod 15 and the other end of which is detachably connected to the second vertical rod 16. The reinforcing connecting rod 18 forms a closed quadrilateral structure with the first vertical rod 15, the second vertical rod 16 and the cross bar 11. The first vertical rod 15 and the second vertical rod 16 have better stability, are not easily deflected by force, and are more conducive to the fixation of the pipeline. The position of the reinforcing connecting rod 18 can be set arbitrarily. Optimally, the reinforcing connecting rod 18 is set at the upper end of the first vertical rod 15 and the second vertical rod 16, so that the reinforcing connecting rod 18 is farthest from the pressure plate 12, and the effect of stabilizing the first vertical rod 15 and the second vertical rod 16 is the best.

[0031] In some embodiments, the reinforcing connecting rod 18 is detachably connected to the first vertical rod 15 and the second vertical rod 16 by bolts or latches. Figure 1 As shown, the reinforcing connecting rod 18 is detachably connected to the first vertical rod 15 and the second vertical rod 16 through a fastener, specifically a right-angle fastener. The reinforcing connecting rod 18 is detachably connected to the first vertical rod 15 and the second vertical rod 16 through a fastener, which makes it easier to adjust the positions of the first vertical rod 15 and the second vertical rod 16.

[0032] In the utility model, the horizontal rod, the vertical rod and the reinforcing connecting rod are all made of steel pipes. In order to prevent damage to the pipeline, the medium pressure plate of the utility model is preferably made of plastic plate, such as polyethylene plate, polypropylene plate, polystyrene plate, etc.
