Abstract
A drilling rod of anchor rod drilling machine whose drilling rod is arranged in its center is a hollow rod with the connecting slot at its lower end for connecting drill bit and the top end linked with power unit for driving the drilling rod. Its construction method includes such steps as drilling to designed depth, putting spiral steel bars in the hollow drilling rod, pouring cement mortar, and withdrawing the drilling rod.
Description
Technical field: the present invention relates to bolt support equipment, be specially the drilling rod and the job practices of a kind of center emplacement type jumbolter.
Background technology: at present, known anchor bolt construction is higher in groundwater table, mud, sand bed etc. is under the geological conditions of pore-forming, most adopt that to lose the bar method be that geologic drilling rod creeps into soil layer and reaches design length, inject cement paste from the bar heart then, reach intensity and expand and draw Deng cement paste, a just whole section geologic drilling rod is all stayed in the hole.The method cost is higher.At first the every linear meter cost of this anchor body of geologic drilling rod (drill bit adds nut and adds drilling rod) is more than 5 times of rib-loop reinforcing bar and steel strand, and does not have the prestressing force effect bad, very easily causes waste at slip casting ten thousand faces; Big as drift sand, loose geology porosity, very easily cause cement paste to run off in a large number, and annotate discontented slurry in the hole, not only cause significant wastage and anchored force not strong.Duration is grown (cement paste just can reach certain intensity on 7th) in addition.
Summary of the invention: the drilling rod and the job practices that the object of the present invention is to provide a kind of simple in structure, with low cost, safe and reliable, energy conservation, easy construction, the center emplacement type jumbolter of reduction of erection time.The object of the present invention is achieved like this: it comprises drill bit (1), drilling rod (2), draw-in groove (3), kelly (4), hollow (5), cement mortar, cement paste (6), screw-thread steel (7), soil layer face (8), Grouting Pipe (9), drill bit group (10), collapsible wing plate (11), connecting axle (12), screw (13), unit head (14).A, drilling rod (2) are the logical hearts, have draw-in groove (3) to be connected with kelly (4) tight fit on the drill bit (1) in the termination of drilling rod (2); After drill bit (1) and drilling rod (2) connected, head on drill bit (1) by drilling rod (2) and creep into soil layer face (8), after reaching design length, open after drilling rod (2) other end and unit head (14) junction, can adopt following two kinds of job practicess: method 1, screw-thread steel (7) is placed in the drilling rod hollow (5) by drilling rod (2) center, elder generation's cement injection mortar (6) in drilling rod hollow (5), then unit head (14) and drilling rod (2) are connected and withdraw from drilling rod (2), screw-thread steel (7) and cement mortar (6) are stayed in soil layer face (8) hole, whenever withdraw from a joint drilling rod cement mortar of after-teeming (6), stay free section to treat to draw with soil blocking pile is bloated after cement mortar reaches intensity, method 2, screw-thread steel (7) and Grouting Pipe (9) are placed in the drilling rod hollow (5) by drilling rod (2) center together, unit head (14) and drilling rod (2) connected withdraw from drilling rod (2), screw-thread steel (7) and Grouting Pipe (9) are stayed in soil layer face (8) hole, by Grouting Pipe (9) slip casting in soil layer face (8) hole, treat to draw with soil blocking pile is bloated after cement paste (6) reaches intensity then.B, drill bit (1) are one with drill bit group (10), upward be connected with collapsible wing plate (11) in drill bit group (10) by connecting axle (12), collapsible wing plate (11) is folding at 0-90 °, be connected with draw-in groove (3) on the drilling rod (2) at the kelly (4) on the drill bit group (10), screw-thread steel (7) is threaded with screw (13) on the drill bit group (10) in hollow (5) of drilling rod (2).
Description of drawings: Fig. 1 is drill bit of the present invention, jackrod structure principle schematic; Construction principle schematic when Fig. 2 works for the present invention; Construction principle schematic when Fig. 3 has Grouting Pipe work for the present invention; Fig. 4 is that drill bit of the present invention, drilling rod are the structural principle schematic diagram of one; Fig. 5 is a drill bit group A-A cross-section structure principle schematic of the present invention.
The specific embodiment: a, drilling rod (2) are the logical hearts, have draw-in groove (3) to be connected with kelly (4) tight fit on the drill bit (1) in the termination of drilling rod (2); After drill bit (1) and drilling rod (2) connected, head on drill bit (1) by drilling rod (2) and creep into soil layer face (8), open after reaching design length, drilling rod (2) other end is with after unit head (14) is connected, can adopt following two kinds of job practices: embodiment 1, screw-thread steel (7) is placed in the drilling rod hollow (5) by drilling rod (2) center, elder generation's cement injection mortar (6) in drilling rod hollow (5), then unit head (14) and drilling rod (2) are connected and withdraw from drilling rod (2), screw-thread steel (7) and cement mortar (6) are stayed in soil layer face (8) hole, whenever withdraw from a joint drilling rod cement mortar of after-teeming (6), stay free section to treat to draw with soil blocking pile is bloated after cement mortar reaches intensity, embodiment 2, screw-thread steel (7) and Grouting Pipe (9) are placed in the drilling rod hollow (5) by drilling rod (2) center together, unit head (14) and drilling rod (2) connected withdraw from drilling rod (2), screw-thread steel (7) and Grouting Pipe (9) are stayed in soil layer face (8) hole, by Grouting Pipe (9) slip casting in soil layer face (8) hole, treat to draw with soil blocking pile is bloated after cement paste (6) reaches intensity then.Embodiment 3, drill bit (1) is an one with drill bit group (10), upward be connected with collapsible wing plate (11) in drill bit group (10) by connecting axle (12), collapsible wing plate (11) is folding at 0-90 °, be connected with draw-in groove (3) on the drilling rod (2) at the kelly (4) on the drill bit group (10), screw-thread steel (7) is threaded with screw (13) on the drill bit group (10) in hollow (5) of drilling rod (2).Drilling rod heads on the drill bit group and advances the soil layer face, reach projected depth after, withdraw from drilling rod, the tractive screw-thread steel makes the collapsible wing plate of drill bit group open barb to live the soil layer face and play the tension effect.
