Microwave irradiation assisted bedding slope local reinforcement method
The invention relates to a microwave irradiation assisted bedding slope local reinforcement method in the technical field of slope engineering. The method comprises the following steps of: determiningthe first section slippage length of a bedding slope and the local reinforcement range and thickness of the slope, performing pre-drilling construction, feeding a vertical waveguide tube into a drilled hole after the construction is completed, and fixing the position of the vertical waveguide tube by using a fixing bracket; and starting a microwave generation device, heating a argillization interlayer around the drilled hole by using the waveguide tube, turning off a power supply after microwave irradiation is completed, taking out the vertical waveguide tube, and treating the next drilled hole after the design standard is met. According to the method, the characteristics of local slippage and progressive instability of the bedding slope with relatively large slope length are combined, the first section slippage length and the local reinforcement range are determined, the argillization interlayer around the drilled hole is rapidly heated by using microwaves in advance, the engineeringcharacteristics such as mechanical strength and water stability of a rock-soil body are improved, construction can be continuously performed by combining proper reinforcement measures, the slope reinforcement efficiency is greatly improved, and the engineering cost is saved.
本发明涉及边坡工程技术领域的一种微波辐照辅助顺层边坡局部加固的方法，其包括以下步骤：确定顺层边坡首段滑移长度、边坡的局部加固范围和厚度，进行预钻孔施工，将竖向波导管送入施工完成后的钻孔中，并用固定支架固定其位置。启动微波发生装置由波导管对钻孔周围的泥化夹层进行加热，微波辐照完成后关闭电源，取出竖向波导管，达到设计标准后再处理下一钻孔。本发明结合坡长较大顺层边坡局部滑移且渐进性失稳的特点，确定其首段滑移长度以局部加固范围，预先使用微波快速加热钻孔周围的泥化夹层，提高岩土体本身的力学强度以及水稳定性等工程特性，可结合适合的加固措施继续施工，大大地提高了加固边坡的效率，节约工程成本。
