Problems solved by technology
However, some tunnels have complex geological conditions and poor grades of surrounding rocks, which are very prone to hole collapse, and even collapse has already occurred during the drilling process, and it is too late to install hole plugs and other prevention devices
In the case of small stones, the construction site generally uses a lot of water to flush them. When encountering large stones, the diameter of the stone is larger than the diameter of the hole, and it is loose and can move up and down. The drilling machine cannot break it and can only re-drill the hole. , waste time and manpower, produce huge noise and waste water resources, pollute the tunnel environmental sanitation
For components or explosives that require a high layout location, these methods will have a negative impact on the results, fail to meet the detection or blasting requirements, and have a negative impact on engineering construction

The invention discloses a treatment device and method for hole collapse. The treatment device comprises a semicircular long groove; a shovel head hinged with the long groove is arranged at one end ofthe long groove; the shovel head is connected with a control rope; the control rope penetrates through the long groove to extend to the other end of the long groove; an air transmission device is arranged at the other end of the long groove, and is connected with a hollow long pipe; an anchoring agent is placed in the long pipe; air is inflated into collapsed holes through the air transmission device; and the air transmission device can be extruded to push the anchoring agent to the hole collapse places to anchor stones. Accurate placement of explosives or detecting devices can be guaranteed;the construction efficiency and the detecting accuracy are improved; and resources are saved.
Description
technical field [0001] The invention discloses a treatment device and an application method for a collapsed hole after a tunnel blast hole is drilled. Background technique [0002] As my country vigorously promotes the construction of high-speed rail, tunnels, as a convenient transportation hub, are increasingly appearing in engineering construction. Blasting operation is the main method of geotechnical engineering construction. The blasting operation first needs to drill holes, then load explosives and detonating devices in the blastholes, and finally detonate the rock. As well as burying and placing components or receiving devices in geological forecasting, etc., drilling is required. However, some tunnels have complex geological conditions and poor surrounding rock grades, which are extremely prone to hole collapse, and even hole collapse has already occurred during the drilling process, and it is too late to install hole-collapse prevention devices such as blast hole pl...
