Description
Technical field
A kind of micropore castinplace pile of solar photovoltaic bracket basis involved by the utility model, is particularly useful for the photovoltaic Project Technical field, ground on clay, sand and Gobi Desert Terrain beach.
Background technology
Along with country's supporting and encourageing energetically new forms of energy project, the impetus development in recent years of solar energy power generating project is good.Photovoltaic generation project is generally divided into ground photovoltaic and the large class of roofing photovoltaic two, the photovoltaic panel bracket basis pattern kind being applicable to ground photovoltaic is at present more, wherein mainly contain single footing, strip foundation, pressing block type basis, counter weight type is basic, prefabricated tubular pile is basic, screw pile foundation etc., according to different photovoltaic panel arrangement, wind load, topography and geomorphology, geological conditions, selected foundation pattern is also not identical.
The construction period of photovoltaic generation project is all shorter, and generally at 2 ~ 3 months, wherein bracket basis is the preceding working procedure of follow-up photovoltaic bracket, solar panels, photovoltaic cable installation, is a vital ring in whole project construction.According to design and construction experience for many years, above several frequently seen photovoltaic bracket basis has following characteristics:
1, single footing, strip foundation
The work progress of single footing, strip foundation is levelling of the land, soil excavation, bed course formwork, blinding concrete cast, basic formwork, reinforcement foundation colligation, base concrete cast, backfilling of earthwork, construction technology process is more, wherein levelling of the land and soil excavation workload are comparatively large, and are subject to inside even from weather; Formwork erection, basic formwork and reinforcing bar binding need a large amount of artificial, long construction period.Single footing, strip foundation are applicable to that landform is comparatively smooth, the good situation of soil condition.Do not advise when topographical elevation difference is larger adopting, reason is to cause basic stand column height to differ, and formwork and reinforcing bar binding work amount increase greatly, or stent support stem height differs, and is unfavorable for factory process.
2, pressing block type is basic, counter weight type is basic
The work progress that pressing block type is basic, counter weight type is basic is levelling of the land, basic formwork, pouring concrete and maintenance, briquetting transport and installation (counter weight type basis no this item).The advantage of two kinds of foundation pattern is can less soil excavation operation, briquetting and counterweight foundation all can industrialization, streamlined construction, also can be prefabricated in the factory and be transported to scene and construct, inferior position is to be only applicable to that landform is comparatively smooth, the good situation of soil condition, when bearing capacity of foundation soil is lower, the more difficult control of foundation uneven settlement, according to basement process then wayward cost.
3, prefabricated tubular pile basis
The construction on prefabricated tubular pile basis is crossed as levelling of the land, factory or site prefabrication, transport, pile foundation construction (static pressure or other forms of construction work).Prefabricated tubular pile basis can solve the problem on pressing block type basis and counter weight type basis, not only be applicable to that landform is comparatively smooth, the good situation of soil condition, all applicable for the situation being positioned at fish, water, river embankment and other bearing capacity of foundation soil lower, and topographical elevation difference change can be solved, design cantilever scope is larger; Inferior position is to execute man-hour requirement piling, material and construction cost higher.
4, screw pile foundation
The construction of screw pile foundation is crossed as levelling of the land, on-the-spot piling.This foundation pattern working procedure is simple, speed of application is fast, cost is low, and processing quality easily ensures, is applicable to that landform is comparatively smooth, the good situation of soil condition, due to screw pile limited length, is not suitable for fish, water, situation that river embankment basis cantilever is larger; When being rich in cobble, rubble in foundation soil, pile top screws in constructional difficulties, is not suitable for adopting this foundation pattern.
Utility model content
Technical problem to be solved in the utility model is, overcomes the shortcoming of prior art, provides the micropore castinplace pile being applicable to solar photovoltaic bracket basis that structure is simple and direct, material is saved, cantilever adjustable range is large, speed of application is fast.
In order to solve above technical problem, the utility model provides a kind of micropore castinplace pile being applicable to solar photovoltaic bracket basis, comprise pile body, primary structure member and concrete, it is inner that described primary structure member is arranged at described pile body, the gap of described Concrete Filled between described pile body and described primary structure member, it is characterized in that: described primary structure member is hollow metal tube, the bottom of described hollow metal tube and the bottom of described pile body adapt to, and the top of described hollow metal tube protrudes from described pile body top and arranges.
Adopt hollow metal tube to replace assembling reinforcement, both decreased colligation, weld interval, and shortened the duration, again save a large amount of artificial, comprehensive benefit is high.Meanwhile, by the exposed length of free adjustment square steel pipe or round steel pipe, the different cantilever height of pile foundation can be realized, topographical elevation difference change can be solved, change the form of construction work that part that traditional bored concrete pile foundation bassets needs formwork.
The technical scheme that the utility model limits further is:
Further, one group of waist hole is offered in the middle and upper part of described hollow metal tube.
Further, described waist hole is four right, is symmetrically between two opened on the tube wall of described hollow metal tube.By offering the mode in waist hole, be conducive to concrete to the filling in pipe, the filling of hole inner concrete is more closely knit, and base integral performance is better.
Further, the middle and lower part of described hollow metal tube arranges one group of dowel.
Further, described dowel is a pair, is symmetricly set on the tube wall of described hollow metal tube.Adding the frictional force of concrete and square tube or pipe by increasing dowel, being more conducive to improving basic upper and low approximations.
Further, the top cross of described hollow metal tube arranges rack connecting plate, and described rack connecting plate is fixed on the tube wall of described hollow metal tube by the stiffener be obliquely installed.
Further, on described support gusset piece, symmetry offers four bolts hole.Described connecting rack plate is connected with upper bracket by bolt.
Further, zinc-plated hole is also offered in the middle of described support gusset piece.Closed after galvanized anticorrosive.
Further, described stiffener is 4, is distributed on the junction of described support gusset piece and metal hollow pipe.
Further, described hollow metal tube is square tube or pipe.
The beneficial effects of the utility model are: micropore bored concrete pile technology provided by the utility model mainly solves photovoltaic bracket foundation construction duration tight, excavation type foundation working process and flow process is more, pile tube high in cost of production problem, are particularly useful for the photovoltaic bracket basis of ground photovoltaic project on clay, sand and Gobi Desert Terrain beach; The utility model changes the way that traditional type bracket basis need install template and reinforcing bar binding, and by ground pore-forming, by the finished product square tube made or pipe fixed placement in hole, then the mode of fluid concrete realizes.Change single footing, strip foundation, pressing block type basis, the basic technique needing to install template of counter weight type, solve the problem of long construction period.
