Description

The construction equipment of concrete pile
Technical field
The utility model relates to field of civil engineering, particularly relates to the construction technology of stake.
Background technology
In the basement process of building, often run into such situation, under earth's surface there are the larger sandy soils of density, crushed stone soil layer, loess formation, gravel boulder bed etc. in certain depth place, and the hardness of these soil layers is uneven, uneven thickness.This geological conditions causes great difficulty to pile body pore-forming during pile foundation construction, the modes such as vibration sinking tube conventional at present, static pressure or rotary drilling, is substantially all difficult to form stake holes to projected depth.Although rotary drilling rig and manually digging hole can in harder soil layer pore-forming, but be all the method that original soil is taken out, soil outward transport clearly is not only needed to cause cost up and environment pollution, and owing to not making full use of original soil and there is no retaining wall, very easily cause hole wall collapse and undergauge, particularly when underground water content is higher, stake holes can be intake very soon, cannot carry out lower step construction.
Summary of the invention
In order to overcome the above-mentioned deficiency of prior art, the utility model provides a kind of construction equipment of concrete pile, by this construction equipment can simply, efficiently disposable complete retaining wall, pore-forming, pile body construction operation, realize the raising of work efficiency and the reduction of cost.
The utility model solves the technical scheme that its technical problem adopts: a kind of construction equipment of concrete pile, include casing, interior pipe, elongated weight, it is characterized in that: the inwall of casing lower end is provided with the thickening layer of certain altitude, comprise liftable interior pipe in casing, interior pipe bottom is fixedly connected with jump bit, comprises liftable elongated weight in interior pipe; The bottom of jump bit is taper, the diameter of taper is less than the internal diameter at casing thickening layer position, and the middle part of jump bit is protruded, and the internal diameter that the diameter of protuberance is greater than casing thickening layer position is less than casing internal diameter, top and the interior pipe bottom of jump bit are connected and fixed, and end face is plane; When inserting pipe and jump bit in connecting in casing, bottom jump bit, taper passes casing thickening layer and leans out outside casing, protuberance in the middle part of jump bit can not be stopped through casing thickening layer, elongated weight striking impact peen face in now promoting in pipe, can realize the synchronous sinking of jump bit and interior pipe and casing; This device also comprises the plane bottom hammer boots that can be connected with jump bit lower end taper.
Best, in the construction equipment of above-mentioned concrete pile, the thickening layer of the inwall of casing lower end, be with the steel-pipe welding of the steel bar of multiple same thickness and length or certain thickness and height on casing inwall.
Best, in the construction equipment of above-mentioned concrete pile, jump bit is solid, forms with steel casting or forging.
Best, in the construction equipment of above-mentioned concrete pile, interior pipe bottom and jump bit upper end connect as one, and when upwards promoting or sink to interior pipe, drive jump bit to be elevated simultaneously.
Best, in the construction equipment of above-mentioned concrete pile, the inside of interior pipe is filled with the filler can alleviating heavy tamping energy.
Best, in the construction equipment of above-mentioned concrete pile, the plane bottom hammer boots be connected with jump bit lower end taper, refer to that shape is corresponding with jump bit cone and to coincide and bottom is flat steel hammers boots into shape.
The beneficial effects of the utility model are:
1. the fast efficiency of speed of fulfiling hole is high: by elongated weight striking impact hammer, the taper of jump bit bottom directly acts on foundation soil body, produce the impact energy being far more than foundation soil body ultimate bearing capacity, make the soil body or rock stratum produce impact failure and form stake holes, drive casing integral sinking simultaneously; 2. hole quality is good: while casing plays retaining wall effect, and be all squeezed into by the soil body be hit with on hole wall bottom stake holes, arrive in and reinforce compacted effect, therefore the solidness of the hole wall soil body is higher, avoids hole wall collapse and undergauge; 3. water sealing effect is good: after pile body pore-forming completes, and need not propose casing and can carry out the construction of lower step operation, even if when underground water content is higher, casing plays the effect of water shutoff all the time, avoids underground water to penetrate in stake holes; 4. can working continuously: in whole work progress, all need not propose casing, by connecting plane bottom hammer boots in jump bit bottom, can also can carry out the squeezed operation of filler of stake end.
