Pier reinforcing device and construction method thereof
The invention discloses a pier reinforcing device and a construction method thereof, and relates to a reinforcing device and a construction method. The hoop units are vertically stacked to be cylindrical and arranged outside a pier cylinder in a sleeving mode. Every two adjacent hoop units are connected through two hoop connecting pieces. Each hoop unit is formed by butting two semicircular protection walls, the upper ends are in butt joint to form a conical connectorand the lower ends are in butt joint to form a conical slot; the hoop connecting piece comprises two U-shaped screw rods and twointernal thread connecting pipes; the opening ends of the two U-shaped screw rods are oppositely arranged, the hoop unit is hung at the connecting end, the two U-shaped screw rods are relatively close to or far away from each other when the internal thread connecting pipe rotates, a grouting hole and four thread through holes are formed in the side wall of the hoop unit, fine adjustment bolts arescrewed in the thread through holes, and the fine adjustment bolts are arranged in the radial direction of the hoop unit. The upper ends and the lower ends of the hoop units are provided with the conical connectors and the conical slots correspondingly, non-rigid connection is achieved, energy dissipation and shock absorption are facilitated, and layer-by-layer grouting from bottom to top is morereasonable.
一种桥墩加固装置及其施工方法，涉及一种加固装置及施工方法。抱箍单元竖向堆叠呈圆筒状并套设在桥墩圆柱外部，每相邻两个抱箍单元之间通过两个抱箍连接件进行连接，抱箍单元为两个半圆形护壁对接构成，上端对接成锥形接头，下端对接成锥形插槽，抱箍连接件包括两个U形螺杆和两个内螺纹连接管，两个U形螺杆开口端相对设置，连接端挂设抱箍单元，内螺纹连接管转动时两个U形螺杆相对靠近或远离，抱箍单元侧壁上开设一个注浆孔以及四个螺纹通孔，螺纹通孔旋接有微调螺栓，微调螺栓沿抱箍单元径向设置。抱箍单元上下两端分别设有锥形接头和锥形插槽，非刚性连接，有利于耗能减震，由下向上逐层灌浆，更为合理。
