Pile foundation reinforcing device and method for urban bridge
The invention belongs to the technical field of bridge construction, aims at solving the problem that when a traditional reinforcing device is used, soil on the upper layer of a riverbed is easily washed away by water flow, and the pile foundation reinforcing effect is affected, and particularly relates to a pile foundation reinforcing device and method for an urban bridge. Four fixing nails and a limiting pipe at the bottom of a fixing seat are inserted into a riverbed, a threaded rod is rotated by driving a rotary knob, so that a pressing head moves downwards, the pressing head is guided in cooperation with a limiting frame, deviation is prevented, in the downward moving process of the pressing head, four overturning frames are pressed, overturning pieces are overturned out of openings, and the pressing head is fixed to the riverbed. When the pressing head moves to the lowest point, the knob makes contact with the top end of the limiting pipe, the end, close to the blocking piece, of the overturning piece is close to the fixing base, the fixing base is matched with the blocking piece to protect and fix soil on the upper layer of the riverbed and prevent the soil from being washed away by water flow, and the bridge pile foundation reinforcing effect of the reinforcing device is guaranteed.
本发明属于桥梁施工技术领域，用于解决传统的加固装置在使用时，河床上层的泥土容易被水流冲走，影响对桩基加固效果的问题，具体是一种用于城市桥梁的桩基加固装置及方法，本发明是将固定座底部的四个固定钉和限位管插到河床内，通过驱动旋钮转动螺纹杆，使得按压头向下移动，配合限位架对其提供导向，防止发生偏移，在按压头向下移动的过程中，对四个翻转架提供按压，使得翻转片从开口处翻转出来，当按压头移动至最低点时，旋钮与限位管的顶端接触，翻转片靠近阻挡片的一端靠近固定座，通过固定座配合阻挡片对河床上层的泥土进行保护固定，防止其被水流冲走，以保证该加固装置对桥梁桩基加固的效果。
