Novel prestressed internal connection concrete precast pile and construction technology thereof
The novel prestressed internal connection concrete precast pile comprises a pile body, inner connection cavities are formed in the two ends of the pile body, inner cavity embedded parts are fixedly installed in the inner connection cavities, and hollow inner connection parts are arranged in the inner cavity embedded parts; concrete layers and mucilage glue are filled between the inner connecting piece and the inner cavity embedded part and in the inner connecting piece, a bottom plate at one end of the cavity embedded part is connected with a grouting pipe, a bottom plate at the other end of the cavity embedded part is provided with a slurry discharging hole, and an anchor shaft penetrating through the inner cavity embedded part and the inner connecting piece at the same time is arranged on the pile body. According to the prefabricated pile, a shroud ring and shroud ring reinforcing ribs are omitted, the homogeneity of pile end concrete and pile body concrete is consistent, the inner connecting cavity and the inner connecting body at the end of the inner connecting pile are arranged in a concentric double-steel-pipe mode at the pile connector, the bending resistance and the shearing resistance of the prefabricated pile are greatly improved, and the prefabricated pile is particularly suitable for row piles in foundation pit supporting; multi-point bolt anchoring is adopted, and the pulling resistance of the internally-connected pile is improved.
本发明公开了一种新型预应力内连接混凝土预制桩及其施工工艺，包括桩本体，桩本体两端设有内连接腔体，内连接腔体内固定安装有内腔预埋件，内腔预埋件内设有呈中空设置的内连接件，内连接件与内腔预埋件之间、内连接件内均填充有混凝土层及粘胶，腔体埋件一端底板连接有注浆管，另一端腔体埋件底板均开有排浆孔，桩本体上设有同时穿过内腔预埋件和内连接件的锚轴。本发明所述预制桩取消包箍和包箍加固筋，使桩端混凝土与桩身混凝土均质性一致，内接桩端部的内连接腔体和内连接体在桩接头处呈同心双钢管设置，使预制桩的抗弯、抗剪性能大幅提高，特别对基坑支护中的排桩尤为适用，本发明采用多点螺栓锚固，提高内接桩的抗拔力。
