Prefabricated bent cap prestress deep-buried anchor sleeve and mounting process thereof

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 convenien
