Description
Technical field
The utility model relates to the anchor bolt construction device in the building field, especially can use a kind of major diameter soil bolt construction equipment in the weak soil layer.
Background technology
In building foundation pit supporting, why traditional anchor pole can not use in soft clay area at traditional anchor pole, mainly receives the too small and creep effect of the too low and traditional grouted anchor bar anchoring body of frictional resistance diameter between weak soil and the anchoring body.Thereby limited the application of bolt support structure, and that traditional interior support supporting and protection structure form exists is long in time limit, cost is high and be not easy to the shortcoming of foundation ditch inside subject structure construction at soft as regional pattern foundation pit supporting structure.
Summary of the invention
The purpose of the utility model is to overcome the shortcoming of prior art, and a kind of major diameter soil bolt construction equipment is provided, and can use in the weak soil layer, and cost is lower, and efficiency of construction is high.
For solving above technical problem, the technical scheme of the utility model is: major diameter soil bolt construction equipment, and its difference is: it comprises and is used for the shower nozzle catcher that is connected with drilling rod and is sleeved on the disposable drill bit on the shower nozzle catcher; Said shower nozzle catcher comprises first steel pipe that is used for being connected with drilling rod, be used for second steel pipe that is connected with disposable drill bit; Disposable drill bit comprises bit body, is connected the drill bit steel pipe at bit body rear portion, loaded plate, steel strand, pier nose pipe, bearing, and wherein first steel pipe, second steel pipe are fixedly connected with one heart, and second outer diameter of steel pipes is less than the drill steel bore; Second steel pipe is provided with shower nozzle and pin key; Drill bit steel pipe rear portion is provided with the groove with the pin key phase configuration, the anterior socket bearing of drill bit steel pipe, and the outer ring of bearing is set with loaded plate; Connect steel strand on the loaded plate; The steel strand top is provided with the pier nose pipe, and said loaded plate is a doughnut-shaped steel plate, and its internal diameter is than the big 2 ~ 3cm of drill steel external diameter of pipe.
The contrast prior art, the beneficial features of the utility model is following:
1), this major diameter soil bolt construction equipment, thereby obtain bigger anchored force and weaken creep effect with enlarged footing through increasing the anchoring body diameter, can use in the weak soil layer;
2), this major diameter soil bolt construction equipment, cost is lower, efficiency of construction is high.

The specific embodiment
Combine accompanying drawing that the utility model is done further explain through the specific embodiment below.
Please refer to Fig. 1, Fig. 2 and Fig. 3, the utility model embodiment major diameter soil bolt construction equipment, it comprises and is used for the shower nozzle catcher that is connected with drilling rod and is sleeved on the disposable drill bit on the shower nozzle catcher; Said shower nozzle catcher comprises first steel pipe 1 that is used for being connected with drilling rod, second steel pipe 2 that is used for being connected with disposable drill bit; Disposable drill bit comprises bit body 12, is connected the drill bit steel pipe 6 at bit body 12 rear portions, loaded plate 7, steel strand 8, pier nose pipe 9, bearing 10, and wherein first steel pipe 1, second steel pipe 2 are fixedly connected with one heart, and second steel pipe, 2 external diameters are less than drill bit steel pipe 6 internal diameters; Second steel pipe 2 is provided with shower nozzle 4 and pin key 3; Drill bit steel pipe 6 rear portions are provided with the groove 5 with pin key 3 phase configuration, drill bit steel pipe 6 anterior socket bearings 10, and the outer ring of bearing 10 is set with loaded plate 7; Connect steel strand 8 on the loaded plate 7; Steel strand 8 tops are provided with pier nose pipe 9, and loaded plate 7 is a doughnut-shaped steel plate, and its internal diameter is than the big 2 ~ 3cm of drill bit steel pipe 6 external diameters.
Further, for playing the fixedly effect of loaded plate 7, add loaded plate back-up ring 11 at the rear portion of loaded plate 7; Loaded plate back-up ring 11, loaded plate 7, being provided with of bearing 10 can guarantee that steel strand 8 are motionless in the disposable drill bit rotation process.
Preferably, the length of second steel pipe 2 can guarantee that shower nozzle 4 stretches into disposable drill bit 5 ~ 10cm.
Preferably,
[0012]Preferably, loaded plate back-up ring 11 is annular steel disc.
The method for using of the utility model major diameter soil bolt construction equipment is: in soft layer; Use specific shower nozzle catcher and disposable drill bit; In the oblique pore-forming of rig, steel strand 8 are brought in the boring, behind the drilling to completion, shower nozzle catcher and disposable drill bit break away from; And beginning churning operation is that gunite forms anchoring body, anchoring body and the large diameter soil bolt of steel strand 8 formation.
Above content is the further explain that combines concrete embodiment that the utility model is done, and can not assert that the practical implementation of the utility model is confined to these explanations.For the those of ordinary skill of technical field under the utility model, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be regarded as belonging to the protection domain of the utility model.
