The invention relates to the technical field of civil construction, in particular to a dual-system progressive grouting plugging device and method.The dual-system progressive grouting plugging device comprises a shallow layer grouting pipe and a deep layer grouting pipe connected into the shallow layer grouting pipe in a sleeved mode and further comprises an inter-pipe separation component arranged between the shallow layer grouting pipe and the deep layer grouting pipe; a grouting hole, a grout outlet and a grout inlet are formed in the pipe wall of the shallow grouting pipe. Water permeable holes and water outlets are formed in the pipe wall of the deep grouting pipe, and the outer side of the pipe wall is sleeved with a water filtering film bag. By means of the arrangement, during grouting of the shallow grouting pipe, the deep grouting pipe plays a role in drainage and pressure relief, on the premise that the safety and the sealing effect of early plugging of a shallow system are guaranteed, the deep grouting pipe is used for plugging of a deep system, leakage water of underground engineering is effectively plugged, and the construction efficiency is improved. And particularly, the reinforcing effect on water leakage plugging of large water volume and high pressure water is more obvious. The structure is simple, the construction period is short, the cost is low, the applicability is high, safety and reliability are realized, and the application prospect is excellent.
本发明涉及土建施工技术领域，特别涉及一种双系统递进式注浆封堵装置及方法，包括浅层注浆管以及套接在浅层注浆管内的深层注浆管，还包括设置在浅层注浆管和深层注浆管之间的管间分隔部件；其中，浅层注浆管管壁上开设有注浆孔、出浆孔和进浆孔；深层注浆管管壁上开设有透水孔、出水口且管壁外侧套接有滤水膜袋。通过上述设置，在进行浅层注浆管的注浆中，深层注浆管起到排水泄压的作用，在保证浅层系统初期封堵的安全和封固效果的前提下，再利用深层注浆管进行深层系统的封堵，有效对地下工程的渗漏水封堵作业，特别是对解决大水量、高压水的渗漏水封堵的加固效果更显著。其结构简单、工期短、成本低、适用性强、安全可靠，具有极好的应用前景。
