Description

Technical Field

[0001] The present invention is mainly used for the treatment of large-channel, large-flow, and high-pressure water hazards generated in the production process of mines, railways, roads, and water conservancy projects, and specifically relates to an integrated device for rapid ground drilling, blocking, and recovery of large-section water inrush channels and an operating method. Background Art

[0002] Mine flooding is one of the five major safety hazards in the process of mine construction and production, especially mine water inrush, which often causes huge casualties and property losses. Mine water inrush often causes mass deaths and injuries. For coal mine water inrush accidents, the commonly used solution in my country is to implement mine drainage and grouting water blocking at the same time. Grouting water blocking is generally divided into two phases. The first phase is to block the water-passing tunnel first, change the water to static water, and the second phase is to treat the water-passing tunnel to completely eradicate the flood. In the first phase of blocking the water-passing tunnel, it is usually to drill holes directly on the ground to the water-passing tunnel, and then put aggregates and other auxiliary materials to fill the water-passing tunnel, change the flow state of groundwater in the tunnel from pipeline flow to infiltration flow, and then carry out grouting consolidation treatment. When facing a water-passing tunnel with a high water flow velocity, directly drilling and filling in aggregates is very easy to be dispersed, not easy to condense, and the success rate is low. In addition, the entire treatment process needs to be changed to seepage flow first, and then grouting is carried out. The project volume is large and the treatment period is long. There is no limit on the grouting range during grouting, which easily wastes the grouting fluid. Therefore, the traditional grouting water blocking technology has poor stability, low blocking success rate and poor stability when facing high water pressure, large flow and large channel water flow.

[0003] In response to the above problems, a new method was introduced in "Zhu Mingcheng, Key Technology and Equipment for Efficient Sealing of Water-Inrush Drilling Holes in Large Water-Moving Channels by Controlled Grouting [J], Coalfield Geology and Exploration, 2015, 43(4): 55-58". The method uses a specific controlled grouting drill to deliver a grout bag into the water-passing tunnel, and then grouting the grout bag in the water-passing tunnel. The pressure generated by the grouting separates the grout bag from the controlled grouting drill and leaves it in the water-passing tunnel. Compared with the above methods, this method avoids the situation where the slurry is dispersed before solidification, and improves the success rate to a certain extent. However, for high water pressure, large flow, and large-channel water movement, this method also has the same problem of high-speed water flow washing away the grout bag, and still does not fundamentally solve the above problems.

[0004] The patent number CN202022290244.1 of the large dynamic water channel water burst drilling grid, airbag, grouting integrated plugging device also has problems such as the bracket cannot adapt to irregular water burst tunnels, cannot achieve drilling and plugging integration, and cannot achieve the recovery of the plugging device. In view of the above problems, it is imperative to develop a large-section water burst channel ground rapid drilling, plugging, and recovery integrated device and operation method.
