A kind of anti-float anchor rod construction long-spiral drilling machine
The utility model relates to construction project anti-float anchor rod technical field of construction, is a kind of anti-float anchor rod construction long-spiral drilling machine concretely.
Anti-float anchor rod is exactly to be anchored to resist a kind of anchor pole that underground water is given sole plate buoyancy in the underground soil layer.Along with rapid development of economy, construction work develops to high-rise, large tracts of land direction gradually, and nearly all high level, building all have basement, garage, and this also makes the application of anti-float anchor rod technology in construction work increase year by year.
Traditional construction technology is continued to use in existing anti-float anchor rod construction always:
Jumbolter is in place------boring---the clear hole of circulating mud------following anchor pole---slip casting tube drawing---secondary grouting of carrying brill of making circulating mud
The anti-float anchor rod employed plant equipment of holing mainly is hydraulic jumbolter or slewing drilling machine etc. in traditional construction technology.The efficient of utilizing hydraulic jumbolter or slewing drilling machine to hole is lower, usually bore a hole and need two to three hours, need to make the mud liquid clear hole of circulating simultaneously, rubble etc. is taken out of outside the hole in will holing, make the job site have a large amount of mud and mud sump like this, these mud sumps need be cleared up, otherwise can influence follow-up construction operation.
In traditional construction technology, anti-float anchor rod needs to utilize pedrail crane to cooperate arriving in the boring under the anchor bar body after pore-forming is finished, and has increased on-the-spot plant equipment and has increased corresponding expense.Transferring when running into obstacle in the process when anchor pole, can only put on anchor pole, anchor pole is descended in the redrilling removing obstacles again.When holing with mud off, silt slurry and cement paste may take place when grout injection to be difficult for differentiating, influx height is not enough, causes the naked anchor pole phenomenon of anhydrous mud parcel.
In traditional construction technology, rig moves needs outer power, and the use crane that condition is good moves, and condition is bad can only manually to be prized, and moves slowly inefficiency.The tradition rig uses diesel engine to be used as power more, and environment is caused certain pollution.
Summary of the invention:
The purpose of this utility model is the deficiency that overcomes above-mentioned prior art, and provides the construction of a kind of anti-float anchor rod use long-spiral drilling machine, mainly solves problems such as rig technology backwardness traditional in the anti-float anchor rod construction, inefficiency, scene are dirty and messy, construction cost height.
In order to achieve the above object, the utility model is achieved in that a kind of anti-float anchor rod construction long-spiral drilling machine, it comprises base, base is divided into stride and hydraulic leg, establishing electronic box on the base, secondary hoisting machine and positive hoisting machine, end at base is established support arm, establish bearing diagonal between support arm and the base, positive hoisting machine is connected with unit head by wire rope, unit head is connected with drilling rod, establishes leading truck between the bottom of drilling rod and base, it is characterized in that described drilling rod is the elongated drilling rod of the rigidity of hollow, Grouting Pipe one end is connected by the internal cavity of flange and drilling rod, and the other end is connected with grouting pump.
Long-spiral drilling machine of the present utility model, its described secondary hoisting machine is connected with vibrating hammer by wire rope, and eccentric motor is arranged on the vibrating hammer.
Long-spiral drilling machine of the present utility model and prior art different be embodied in drilling tool transformation, filling system transformation and increase by three aspects of vibrating hammer.
The transformation of drilling tool mainly is that drilling rod adopts the bigger elongated drilling rod of rigidity, because the anti-float anchor rod aperture is generally 150mm, therefore the diameter of drilling rod is just littler after removing helical blade, the slenderness ratio of drilling rod will be bigger like this, cause the drilling rod unstability easily, therefore must make the bigger elongated drilling rod of rigidity.The high-strength seamless steel pipe of material selection, the outside weld high-strength track steel as helical blade, make drilling rod obtain bigger rigidity.
The transformation of filling system mainly comprises the making of Grouting Pipe and the sealing strengthening measure of grouting port.Long-spiral drilling machine mainly is the construction machinery as the CFG stake traditionally, original casting system mainly is designed for building plain concrete on the equipment, thick and the poor sealing of pipeline, needs according to bolt grouting, Grouting Pipe must be changed carefully, and the sealing of tie point carried out, reach the pressure of 1.5-2.0MP.
Increasing vibrating hammer mainly is to transfer in the process if resistance manually under the situation about can not put into, uses the vibrating hammer vibration to make anchor pole put into anchor hole smoothly at anchor pole.
Compared with the prior art a kind of anti-float anchor rod construction of the present utility model has following positive progress with long-spiral drilling machine: 1, efficiency of construction height; The construction that traditional handicraft is finished an anchor pole needs 2-3 hour, adopts the utility model only to need get final product in 20-30 minute; 2, integrated cost is low; Director's spiral drilling machine of the present utility model can support the efficiency of construction of last at least ten traditional rigs, director's spiral drilling machine of the present utility model only needs 4-5 people to operate, ten traditional rigs then need 40 people to operate, thereby cost of labor reduces greatly; Use traditional rig that mud pit need be set, when boring, use mud off, and long-spiral drilling machine of the present utility model is dried pore-forming operation, does not need mud pit; Oneself is walked, and need not increase mechanically moving; Oneself plays cathead, also need not increase corresponding mechanical work; 3, reliable in quality; Owing to be dried pore-forming operation, can not cause cement paste and silt slurry to obscure, cause the naked anchor pole phenomenon of anhydrous mud parcel, reliable in quality; 4, the vibrating hammer that increases of design inserts anchor pole to put in place, guarantee that rock-bolt length and anchored force reach designing requirement; 5, electrification drives, environmentally safe, and dried pore-forming operation does not form mud sump, on-the-spot neat and tidy.
