Active and passive scouring protection method for wading pile
The active and passive scouring protection method comprises the steps that steel plates are fixedly connected together through supporting beams to form a rigid first protection unit, and a center hole is formed in the middle of each steel plate; floral tubes are installed on the lower steel plate, are distributed at intervals in the circumferential direction of the steel plate and are connected with the grouting branches in a one-to-one correspondence mode; a first protection unit fixedly connected with a floral tube penetrates through the wading pile column from top to bottom, the floral tube is inserted into silt close to the wading pile column, and the first protection unit is flatly placed on the silt surface; grouting is conducted through a grouting pump and permeates into the silt to form a first solidified layer. The pile foundation in the mud bed is reinforced, and due to the fact that the floral tubes are arranged at intervals, curing areas corresponding to the adjacent floral tubes are meshed with each other, and the integrity of the first curing layer is guaranteed; and the first curing layer and the first protection unit are combined, so that the anti-scouring performance is improved, rigidity attenuation of a mud bed soil body within the reinforcing range is effectively restrained, and the stability of the pile foundation under the water flow impact effect is improved.
本发明公开了一种用于涉水桩柱的主被动冲刷防护方法，包括：利用支撑梁将钢板固连在一起形成刚性的第一防护单元，每个钢板的中部具有中心孔；在下方的钢板上安装花管，花管沿钢板圆周方向间隔布设，花管与灌浆支路一一对应连接；将固连有花管的第一防护单元自上而下穿过涉水桩柱，使花管插入靠近涉水桩柱的泥沙内，第一防护单元平放在泥沙面上；利用灌浆泵灌浆并渗透至泥沙内形成第一固化层。本发明对泥床内的桩基进行加固处理，由于花管间隔布设，使相邻花管对应的固化区域相互咬合，保证第一固化层的整体性；第一固化层和第一防护单元相结合，提高了抗冲刷性能，有效抑制加固范围内泥床土体的刚度衰减，提高了桩基在水流冲击作用下的稳定性。
