Abstract
The utility model relates to a photovoltaic foundation steel pipe pile which comprises a pile tip, a pile body, a pile top plate and an adjusting sleeve, wherein the pile tip is arranged at the lower end of the pile body, the adjusting sleeve is sheathed and fixed at the top end of the pile body, and the pile top plate is welded at the top end of the pile body. The photovoltaic foundation steel pipe pile has a simple structure, and is compact and reasonable and attractive in appearance; and the adjusting sleeve can be adjusted within a certain range according to the embedded height of the steel pipe pile, so that the flexibility is higher and the range of application is wider. Compared with similar power stations, the structure reduces the working load of foundation excavation and backfilling, and greatly decreases earth volume; under the condition of a same investment, the difficulty that the concrete in winter can not constructed is solved, the foundation construction speed is quickened, and the labor intensity of constructors is lowered; and the construction difficulty of building a large photovoltaic power station foundation in westward desert regions of China can be effectively solved.
Description
Technical field
The utility model relates to a kind of photovoltaic basis steel pipe pile, specifically can can't substitute the steel pipe pile that uses under the situation on fluid concrete basis on ground, belongs to desert photovoltaic power plant bracket basic technology field.
Background technology
In large-scale desert photovoltaic plant project, in order effectively to reduce the foundation construction cost, convenient construction, reduce the constructor, reduce constructor's labour intensity, reduce the large-scale photovoltaic electric field piece of smooth land, the abominable natural conditions that are unfavorable for cast in situs have been overcome, effectively solved in western Desert Area, build a large-sized photovoltaic electric field foundation construction difficult problem, also effectively overcome simultaneously under the conditions such as winter temperature is low, transportation difficulty, construction foundation excavation difficulty, cause the cost of engineering to increase, the construction delays duration, form the certain economic loss.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point of the prior art, thereby installation aspect, a kind of piling bar basis is provided, the production efficiency height, and labour intensity is low, can overcome the steel pipe pile basis, a kind of photovoltaic basis of constructional difficulties under the special weather condition.
According to the technical scheme that the utility model provides, a kind of photovoltaic basis steel pipe pile comprises the stake point, and pile body is regulated sleeve pipe, and described pile body lower end is provided with the stake point, and described regulating sleeve pipe box dress is fixed on the pile body top.
Described pile body top is welded with a top board, and stake top board and adjusting sleeve pipe weld, and adds weldering reinforcement gusset at vertical four direction.The sharp otch of described stake is welded into pyramid.
The utlity model has following advantage:
The utility model is simple in structure, compact and reasonable, handsome in appearance; Regulating sleeve pipe can be according to the adjusting of highly making certain limit of imbedding of steel pipe pile, and flexibility is higher, and the scope of application is more extensive.With similar power station relatively, this structure decrease the workload of foundation excavation and backfill, significantly reduced earth volume; Under equal investment situation, solved the difficulty that cold weather concrete can't be constructed, accelerated foundation construction speed, reduced constructor's labour intensity; Can effectively solve western Desert Area, build a large-sized photovoltaic electric field foundation construction difficult problem in China.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model pile body top welding stake top board structure schematic diagram.
The specific embodiment
The utility model is described in further detail below in conjunction with the embodiment in the accompanying drawing:
Fig. 1-shown in Figure 2 comprises stake point 1, and pile body 2 is regulated sleeve pipe 3.Described pile body 2 lower ends are provided with stake point 1, and the top on whole steel pipe pile basis is with the fixing pile body 2 of the form suit of regulating sleeve pipe 3, highly regulate the arrival design attitude after the employing welding manner fix.
Described pile body 2 tops are welded with a top board 4, and stake top board 4 and adjusting sleeve pipe 3 weld, and add weldering reinforcement gusset at vertical four direction.
The utility model steel pipe pile is made:
D114 steel pipe pile height 2.85m (not comprising the stake point).The stake point welds the stake point by the roll of steel plate weldering again by figure elder generation bulkhead D114 * 10 of weldering.The 100mm that also pile body can be extended, the sharp otch of stake is welded into pyramid.Absolute altitude is regulated sleeve pipe and is treated to weld after stake is squeezed into.Steel pipe is the conventional galvanizing pipe, requires the thick 0.5mm of brush asphalt varnish.Steel are Q235.Welding rod is E43, and weld seam is 4mm.
Pile foundation construction of the present utility model requires:
The utility model is owing to the control of strength in the piling process is uneven, and pile foundation top mark height is difficult to control consistent, and ad hoc meter absolute altitude is regulated sleeve pipe.Must not be offset greater than 25mm in the pile foundation center.Pile foundation pile body depth of drive error is ± 100mm.Absolute altitude is regulated the sleeve pipe postwelding and is required with pile foundation top mark height from design terrace+0.50 meter.Drive piles again after can only getting out the frozen soil part when frozen soil appears in the top layer, job site with the drill bit of D114.Must not enlarge the bore diameter and the degree of depth.
The utility model privileged sites are handled:
The utility model has the cable trench place near pile foundation, requiring the cable furrow bank is the thick C20 concrete of 200mm furrow bank, and furrow bank bankets outward and must layering put in order real.When cable trench wall thickness during less than 200mm, the cable furrow bank is arrangement of reinforcement suitably.The pile foundation seat must layering be put in order real before equipment is installed and used at the backfill or the place of loosening the soil.
The utility model stake top board requires:
The stake top board is regulated the logical weldering of the thick weld seam of sleeve pipe 4mm with the stake top mark is high, and adds weldering at vertical four direction and strengthen gusset.
When the utility model uses, can use pile driver that steel pipe pile is squeezed at the anchor point of measuring in advance, steel pipe pile be imbedded the control that should note design elevation in the process, and height tolerance among a small circle can be regulated by the sleeve pipe regulated at steel pipe pile top.
The link that should be noted that is: the control of pile body 2 top absolute altitudes, the control of pile body verticality can adopt welding manner to fix with after regulating sleeve pipe 3 tops and being adjusted to design elevation.
