Abstract

The invention discloses a post-tensioning method prestressed grouting stock outlet structure. The post-tensioning method prestressed grouting stock outlet structure comprises a prestressed tendon, ananchor ring, an anchor bearing plate and a corrugated pipe, the anchor ring is installed on the outer portion of the prestressed tendon in a sleeving mode, the corrugated pipe is connected with a vertical steel pipe, and the corrugated pipe and the vertical steel pipe are connected in a sealing mode. The corrugated pipe and the vertical steel pipe are installed on the outer portion of the prestressed tendon in a sleeving mode, the anchor bearing plate is installed on the outer portion of the vertical steel pipe in a sleeving mode, and the vertical steel pipe is further connected with a horizontal steel pipe. A plastic hose is connected to the other end of the horizontal steel pipe, and the interiors of the corrugated pipe, the vertical steel pipe, the horizontal steel pipe and the plastichose mutually communicate. According to the post-tensioning method prestressed grouting stock outlet structure, the problem of poor exhaust and leakage during hole grouting is solved through the mutual communication of the vertical steel pipe, the horizontal steel pipe and the corrugated pipe, meanwhile, the vertical steel pipe is connected with the anchor bearing plate, and the stiffness of components is improved.

Description

technical field [0001] The invention relates to the technical field of prestressed grouting construction, in particular to a post-tensioning prestressed grouting outlet structure. Background technique [0002] Prestressed tension is to pre-load the tension in the component in advance, so that the prestressed tensioned component bears the tensile stress, and then makes it produce a certain deformation to cope with the load on the structure itself. Before the engineering structural components are subjected to external loads, applying pre-tension stress to the steel strands in the tension module can improve the bending resistance and stiffness of the components, delay the appearance of cracks, and increase the durability of the components. For the mechanical structure, pre-stressing it can improve the rigidity of the structure itself, reduce vibration and elastic deformation. This can significantly improve the elastic strength of the tension module and make the original resista...
