Embodiment Construction
[0021] Embodiment 1 of connecting drill pipe with pressure, such as Figure 1-2 As shown, the continuous drill pipe with pressure includes a drill pipe section 101 and a pressure hose 102, wherein the number of drill pipe sections 101 can be set according to actual needs, and the length of the pressure hose 102 should not be less than the length of the drilled hole at the construction site. The distance between the front end and the corresponding pressing equipment.
[0022] Both ends of the drill pipe segment 101 are respectively provided with connecting structures for connecting with adjacent drill rod segments. The bolt socket 11 at the tongue-and-groove structure, wherein one of the two tongue-and-groove structures located at both ends of the drill pipe segment is a male tongue and groove 12, and the other is a female tongue and groove 13. When connecting, the corresponding two drill holes The rod segments can be positioned through the male and female grooves, and then th...

The invention relates to the field of geotechnical engineering construction and in particular relates to a continuous drill pipe under pressure, a swing-jet grouting device using the drill pipe and a swing-jet grouting construction method. The continuous drill pipe under pressure comprises more than two drill pipe segments; a connection structure is arranged between every two adjacent segments; at least one pipeline mounting structure for mounting a corresponding pressurizing hose is arranged on the outer peripheral surface of each drill pipe segment, and the pressurizing hose is used for supplying a fluid medium to a corresponding jet cutting head. As at least one pipeline mounting structure for mounting a corresponding pressurizing hose is arranged on the outer peripheral surface of each drill pipe segment and the pressurizing hose is used for supplying the fluid medium to the corresponding jet cutting head, drilling power can be provided for the jet cutting head by arranging the pressurizing hoses in the pipeline mounting structures in the construction process; when the drill pipe needs to be connected, only the corresponding drill pipe segments needs to be added without relieving pressure on the pressurizing hoses and the jet cutting heads; as a result, the blockage of the jet cutting head and the drill pipe can be avoided.
Description
technical field [0001] The invention relates to the field of geotechnical engineering construction, in particular to a continuous drill pipe with pressure, a pendulum spraying device and a pendulum spraying construction method using the drill pipe. Background technique [0002] Bolt support is of great significance in slopes, tunnels, stopes and other environments. In fact, the mechanical state of the surrounding rock itself can be changed through the bolts installed inside the surrounding rock, so as to achieve the purpose of maintaining the stability of the surrounding rock. It is A support method of active defense is a major change in mine support. At present, bolt support has many advantages such as good support effect, low material consumption, simple construction, convenient mechanized operation and fast construction speed. [0003] At present, the two methods with obvious advantages in bolt support construction are rotary spraying and pendulum spraying. Both rotary s...
