本部分的陈述仅仅是提供了与本发明相关的背景技术信息，不必然构成在先技术。
在隧道施工过程中，水害问题普遍且突出，不但影响施工质量、延误进度、增加成本，甚至酿成严重工程事故。注浆是当前水害防控最常用的方法，浆液随着时间逐步完成由液相向固相的转变进而实现赋水通道封堵以及地层的有效加固，在隧道施工中发挥着至关重要的作用。
各地地质环境差异较大，针对不同地质地层条件的突涌水害治理，要根据地质地层特点进行方案设计。砂卵石等孔隙介质充填的漏失地层，普遍于成都平原、北京小平原等冲积扇平原，此类孔隙介质地层力学性质不稳定，注浆加固时容易漏失浆液，常导致浆液用量明显提升却不能有效稳固地层，目前对此尚无令人满意的处理办法，只能通过多开孔、多注浆或采用固化快的浆液来尽量满足要求。局部地区的孔隙介质地层受高温热泉以及高地温的影响，常规的浆液材料在此种环境下注浆易失效，而高温水的存在导致水害治理难度更大。因此，探明此类介质环境中的浆液封堵扩散机理尤为重要。目前针对孔隙介质注浆开展的模型试验尚未能充分考虑孔隙地层富水程度以及水温、地温效应等多因素耦合条件下的浆液扩散机理探究，且不能实现孔隙介质地层注浆浆液扩散过程的精确可视化。在开展模型试验方面，现有的注浆设备同样无法满足可控恒速注浆以及储浆与清洗的便捷性。
