Post-tensioned non-adhesive reusable prestressed reinforcement support pile
A post-tensioned non-adhesive reusable prestressed reinforcement support pile comprises a pile body, a prestressed reinforcement and flange plates at the two ends, the pile body is a concrete solid pile body containing a common steel wire mesh, the prestressed reinforcement is a finish-rolled deformed steel bar, the two ends of the finish-rolled deformed steel bar are made into threaded rods, and the flange plates are connected with the threaded rods. The finish rolling deformed steel bar can be repeatedly used, and the flange plate is an end flange plate with a concave middle part and a hole. The prestressed steel bars accounting for a large proportion of the cost of the support pile can be recycled, and the manufacturing cost is effectively reduced; after being driven into a foundation, the supporting piles mainly bear transverse thrust, after foundation pit backfilling is finished, the supporting piles lose the original value, and pre-stressed steel bar embedding is meaningless; after the engineering is finished, the prestressed finish-rolled deformed steel bar is recycled, so that the engineering economic cost can be greatly reduced, and meanwhile, the resource consumption can be reduced. The application prospect is wide.
一种后张无粘接可重复利用预应力钢筋的支护桩，支护桩包括桩身、预应力筋以及两端的法兰盘，所述桩身为包含普通钢丝网片的混凝土实心桩体，所述预应力筋为精轧螺纹钢棒，精轧螺纹钢棒的两端制作为螺纹杆，该精轧螺纹钢棒可多次反复使用，所述，法兰盘是一种中部凹入并带孔的端法兰盘。本发明可使占支护桩成本较大比例的预应力钢筋重复利用，有效降低造价；支护桩在打入地基后，主要承受横向推力，基坑回填结束后，支护桩失去其原有价值，预应力钢筋埋置并无意义；工程结束后预应力精轧螺纹钢的回收，可大幅度降低工程经济成本，同时也可减小资源消耗。应用前景广阔。
