Description

Technical Field

[0001] The utility model relates to the technical field of prestressed engineering, in particular to a rubber hose connection device for the prestressed anchoring end of a continuous beam bridge. Background Art

[0002] Prestressed engineering is to apply pre-tensioning stress to the steel bars in the tension module before the engineering structure components are subjected to external loads, thereby increasing the stiffness of the components, delaying the appearance of cracks, and increasing the durability of the components. For mechanical structures, it means to generate stress in advance, which has the advantage of increasing the rigidity of the structure itself and reducing vibration and elastic deformation. This can significantly improve the strength of the tension module and make the original resistance stronger.

[0003] When carrying out longitudinal prestressed grouting construction work on a bridge, the traditional method is to connect a hose from the anchor end to the top plate and then carry out grouting. This is a single grouting construction. This method consumes more materials and is more likely to cause pipe blockage, so it needs to be improved. Utility Model Content

[0012] Preferably, the water bag is an annular structure, and the inner wall of the water bag is attached to the outer wall of the connector.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] (1) The device can perform grouting construction on the inside of two corrugated pipes at the same time, thereby improving the grouting efficiency and avoiding blockage inside the corrugated pipes.

[0015] (2) This device forms a channel between the two adjacent corrugated pipes by connecting a soft rubber tube between the grouting ports of the two corrugated pipes, so that slurry can enter from one corrugated pipe and exit from the other corrugated pipe, thereby improving the grouting efficiency.

[0016] (3) The device sets a sleeve between the grouting port and the connecting head of the soft rubber tube. The grouting port and the soft rubber tube can be quickly connected through the sleeve. At the same time, the expansion of the water bag inside the sleeve can ensure the sealing of the connection between the grouting port and the soft rubber tube, thereby avoiding leakage during the grouting process.
