Abstract

The invention relates to a prefabricated bent cap prestress deeply-buried anchor sleeve and a mounting process thereof. The deep-buried anchor sleeve comprises a wedge block, a first fixing block anda second fixing block, the wedge block, the first fixing block, the second fixing block and the wedge block are movably spliced in sequence to form the deep-buried anchor sleeve, and the wedge block is embedded between the first fixing block and the second fixing block. By means of the deep-buried anchor sleeve, on one hand, the position of an anchorage device in the concrete pouring process is fixed, and compared with a traditional PVC deep-buried anchor sleeve, the deep-buried anchor sleeve of the invention is more stable in structure and relatively large in strength; and on the other hand,the wedge-shaped block, the first fixing block and the second fixing block are spliced for use, so on the premise that the strength of the deep-buried anchor sleeve is guaranteed, the deep-buried anchor sleeve can be conveniently dismounted after concrete pouring is completed, the dismounted deep-buried anchor sleeve can be repeatedly used, and the wedge-shaped block of the wedge-shaped structureis more convenient for dismounting the deep-buried anchor sleeve.

Description

technical field [0001] The invention relates to the technical field of building bridges, in particular to a prefabricated cap beam prestressed deep-buried anchor sleeve and an installation process thereof. Background technique [0002] In the rapid prefabricated viaduct bridge, in the prefabricated component production process, during the prestressing construction, leaving the prestressing tension notch and sealing the anchor is an indispensable process. As the technology becomes more and more mature, the prestressed deep buried tube has the characteristics of convenient construction and easy anchor sealing. [0003] However, some of the current deep buried tubes are made of PVC pipes, and some are made of iron deep buried tubes. For deep-buried pipes made of PVC pipes, connecting parts are needed when the pipes are connected to the end mold of the cover beam. When these connecting parts are connected to the PVC pipes, due to the strength of the PVC pipes, the connection st...
