Description

A kind of modified bored pile construction rig
Technical field
The utility model is related to drilling rig technique field, specially a kind of modified bored pile construction rig.
Background technology
Percussive drilling pile driving construction is using drill hole of drilling machine, retaining wall pore-forming(Ground is acted on without jam-packed)On the spot under priming petock A kind of construction technology of concrete technology pile.This technique be suitable for stratum for lam, sand, flour sand and containing a small amount of granule ground Layer, using slurry strengthened wall impact drill bradawl hole, the drilled pile of a diameter of 0.8-2.0m.Existing drill configuration is depending on the soil body is passed through Cross the hammering that adds water and be changed into mud, causing scene to be badly in need of a large amount of mud needs treatment, and its mud conditioning is costly, not only economical Cost is high and causes environmental pollution, while rate of penetration is too slow.
The content of the invention
The purpose of this utility model is to provide a kind of modified bored pile construction rig, to solve above-mentioned background The problem proposed in technology.
To achieve the above object, the utility model provides following technical scheme:A kind of modified bored pile construction is used Rig, including chopping bit body and rig body, the chopping bit body bottom portion are provided with hanger, and the impact drill is bored Head body is divided into impact cone and core drill bucket, and steel wire rope is connected with the hanger, and the rig bodies top is provided with support frame, Support frame as described above top is provided with drive, and the wire rope gearing is connected to drive, and extends to rig body interior.
Preferably, it is in circular arc that core drill bucket junction is located in the impact cone.
Preferably, the core drill bucket is grab jaw type.
Preferably, the impact cone and core drill bucket inside are equipped with cavity structure.
Preferably, the rig body bottom portion is provided with includes motor and driving wheel in roller, the rig body, and Motor and driving wheel are connected by belt, and steel wire rope is connected with driving wheel.
Compared with prior art, the beneficial effects of the utility model are:A kind of modified cast-in-situ bored pile of the utility model Construction rig, structure is novel, easy to operate, and the chopping bit pile quality of use is good, and pile body integrality is good.Construction Process machinery is relatively small, and site condition requirement is relatively low, has the soil nailing of former pattern foundation pit supporting structure and the poor strata of anchor cable to have to underground Fine applicability, with practicality very high, greatly improves a kind of use of modified bored pile construction rig Feature, it is ensured that its using effect and utilization benefit, is adapted to be widely popularized.
Brief description of the drawings
Fig. 1 is the utility model overall structure diagram;
Fig. 2 is the utility model chopping bit body construction schematic diagram.
In figure:1 chopping bit body, 2 rig bodies, 3 hangers, 4 impact cones, 5 core drills bucket, 6 steel wire ropes, 7 transmissions Wheel, 8 support frames, 9 rollers.
Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment for being obtained, belongs to the scope of the utility model protection.
Fig. 1-2 is referred to, the utility model provides a kind of technical scheme:A kind of modified bored pile construction is bored Machine, including chopping bit body 1 and rig body 2, the bottom of chopping bit body 1 are provided with hanger 3, the impact drill 1 point of drill body is impact cone 4 and core drill bucket 5, and steel wire rope 6 is connected with the hanger 3, and the top of the rig body 2 sets There is support frame 8, the top of support frame as described above 8 is provided with drive 7, and the steel wire rope 6 is connected in drive 7, and extends to brill It is in circular arc that 5 junctions of core drill bucket are located inside machine body 2, in the impact cone 4, and the core drill bucket 5 is grab jaw type, institute State and be equipped with cavity structure inside impact cone 4 and core drill bucket 5, the bottom of rig body 2 is provided with roller 9, the rig sheet Include motor and driving wheel in body 2, and motor and driving wheel are connected by belt, and steel wire rope is connected with driving wheel 6。
Operation principle:A kind of modified bored pile construction rig of the utility model, when using, device is moved to Working region, steel wire rope 3 is driven downwards by the motor in rig body 2, drives chopping bit body 1 to undershoot Hit, core drill bucket 5 launches, core drill bucket 5 is tightened up and the soil body is caught the soil body extruding when above carrying, and will be impacted by rig body 2 The lifting of drill bit body 1 is removed, and the soil body is laid down, and mud off is used when running into water, and impact is directly used when running into barrier Cone 4 is used as impact main body.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art, It is appreciated that these embodiments can be carried out various changes in the case where principle of the present utility model and spirit is not departed from, repaiies Change, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
