Description
Technical field
The utility model relates to field of civil engineering, particularly relates to the construction equipment of stake.
Background technology
In the basement process of building, bored pile is conventional base form, it improves the bearing capacity of stake mainly through pile body side friction and part end resistance, running into the higher building of requirement for bearing capacity, or during the situation that in ground, soft layer is darker, by strengthening the mode of pile body diameter and pile body length, building demand must be met, therefore construction cost is higher, and the duration is longer.Develop again a kind of novel support disk pile in recent years, it is by arranging force bearing disk or load branch raising bearing capacity of pile tip, namely by squeeze equipment at the squeezed formation of appropriate depth expanding disk space with one heart, reach the object that improves bearing capacity ofconcreting thus save cost or reduction of erection time.But the damaged condition of plant equipment often can be there is in this pile-type in construction, its reason is, when squeeze equipment forms expanding disk space by rotation mode, want the squeezed requirement of compact earth to the rigidity of squeeze equipment and power of motor all very high, therefore the spoilage of construction equipment is exacerbated, particularly in gravelly soil, sand etc. comparatively hardpan, be difficult to pile, cause the increase of cost and the prolongation of duration.
Summary of the invention
The utility model proposes to solve the above problems, object is the construction equipment providing a kind of squeezed shaped pile, efficiently special pile body construction is carried out rapidly by this device, and disposablely can complete the expanding and concrete perfusion operation of pile body, realize the raising of work efficiency and the saving of cost.
To achieve these goals, the construction equipment of squeezed shaped pile of the present utility model, include actuating unit, interior pipe, outer tube, drill bit, it is characterized in that: actuating unit to be connected with interior pipe by flange and interior pipe can be driven to rotate, interior pipe outside is provided with outer tube, outer tube and interior pipe by key connect can together with rotate, actuating unit lower end is provided with hydraulic jack, hydraulic jack upper end is connected with actuating unit, lower end is connected with outer tube top by slew gear, interior pipe racks moves hydraulic jack when outer tube rotates and does not rotate, the junction, bottom of inner and outer tubes is provided with squeezed mechanism, squeezed mechanism presses down outer tube by hydraulic jack and produces that displacement is backward outer to be strutted, realize extruding hole wall soil body formation stake holes expanding, interior pipe bottom is provided with drill bit.
In the construction equipment of above-mentioned squeezed shaped pile, above-mentioned construction equipment is when constructing, drive inner and outer tubes to rotate by actuating unit simultaneously, drive the downward soil compaction pore-forming of drill bit, when pore-forming is to projected depth, oil cylinder is driven to make inner and outer tubes produce displacement, strut the squeezed mechanism extruded hole wall soil body, then concrete perfusion in the inside pipe in one side, inner and outer tubes and squeezed mechanism is driven upwards to promote while promote unit head, in lifting process, to form stake holes expanding and pour into pile concrete simultaneously for the squeezed mechanism continuously extruded hole wall soil body, until foundation surface, form the shaped pile of the larger and pile body of diameter with several michinaga ribs.
In the construction equipment of above-mentioned squeezed shaped pile, above-mentioned actuating unit comprises one or several combinations of auger unit head or diesel hammer or weight or vibration head.
In the construction equipment of above-mentioned squeezed shaped pile, above-mentioned squeezed mechanism is made up of 2 ~ 10 telescopic arms, and telescopic arm is connected by pivot pin with underarm by upper arm, and upper arm upper end is connected with outer tube bottom, and underarm lower end is connected with interior pipe.
In the construction equipment of above-mentioned squeezed shaped pile, above-mentioned squeezed mechanism is to when being lowered into inner and outer tubes, and the telescopic arm of squeezed mechanism inwardly closes up, and when upwards promoting inner and outer tubes, the telescopic arm of squeezed mechanism is to outer support.
In the construction equipment of above-mentioned squeezed shaped pile, above-mentioned drill bit is provided with discharging opening, and discharging opening is communicated with the internal pipeline of interior pipe.
The characteristics and advantages of the construction equipment of above-mentioned squeezed shaped pile is:
1. first carry out the pile body pore-forming of minor diameter, after pile body is expanding, forms major diameter pile body, even if in the harder soil layer such as sandy soils, boulder bed, also rapidly and efficiently construction can be completed.2. by controlling the angle of outside diastole of the telescopic arm of squeezed mechanism, the expanding size of pile body can be adjusted at any time, by change the telescopic arm of squeezed mechanism quantity and shape, pile body shape of cross section can be changed, namely change pile body week lateral area.3. stake holes surrounding soil to be all squeezed into bottom stake holes and on hole wall, to play and reinforce compacted effect by formation of pile, pore-forming and pile quality high.4. pore-forming, retaining wall, soil compaction whole operations that are expanding, pile once complete, and the fast efficiency of speed is high.
