Abstract
The utility model relates to a cylindrical pile foundation structure suitable for photovoltaic engineering. The cylindrical pile foundation structure comprises a cylindrical concrete pile and a reinforcement cage, wherein a PVC (Poly Vinyl Chloride) sleeve is wrapped at the outer circle of the cylindrical concrete pile; the reinforcement cage is arranged inside the cylindrical concrete pile; a pre-embedded steel plate is arranged at the top of the cylindrical concrete pile; a fastening component is fixed on the pre-embedded steel plate. The cylindrical pile foundation structure can completely satisfy the requirement of a bracket on fixation and safety, and is simple in structural form, convenient to construct and low in cost.
Description
Technical field
The utility model relates to a kind of cylinder pile foundation structure that is applicable to the photovoltaic engineering, belongs to photovoltaic engineering foundation structure field.
Background technology
The photovoltaic module of 1MW needs thousands of fixed supports.It is firm that fixed support need be connected with the basis under it to keep.Present bracket basis adopts independent foundation under column or strip foundation under columns (seeing accompanying drawing 1) mostly.Because support bracket fastened quantity is very many, and scope is wider, adopt the efficiency of construction of independent foundation under column or strip foundation under columns low, and engineering quantity is bigger.
The utility model content
The purpose of this utility model is, at the defective of prior art, provides a kind of cylinder pile foundation structure that is applicable to the photovoltaic engineering.
The technical solution of the utility model is: a kind of cylinder pile foundation structure that is applicable to the photovoltaic engineering, comprise concrete cylindrical stake and reinforcing cage, it is characterized in that: the outer ring of concrete cylindrical stake is surrounded by the PVC sleeve pipe, and there is reinforcing cage inside, pre-embedded steel slab is arranged at the top, and securing member is fixedly arranged on the pre-embedded steel slab.
Above-mentioned securing member is bolt.
Above-mentioned PVC sleeve pipe is useful on the reinforcing bar of fixing PVC sleeve pipe outward.
The utility model is with the template of PVC sleeve pipe as perforate retaining wall and concrete cylindrical stake, by adjusting diameter, length and the buried depth of PVC sleeve pipe, can adjust diameter, height and the buried depth of concrete cylindrical stake, thereby requirement for bearing capacity, the overturning or slip resistance analysis of satisfying the concrete cylindrical pile foundation require and the resistance to plucking requirement; And by burying the pre-embedded steel slab that bolt is fixedly arranged underground, satisfy the requirement of fixedlying connected with upper bracket.
The cylinder pile foundation structure that the utility model provides satisfies the fixing requirement of support and safety requirements fully, and structural shape is simple, and it is very convenient to construct, and cost is low.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the support independent foundation under column structural representation that adopts at present;
Fig. 2 is the structural representation of the utility model embodiment;
Fig. 3 is the vertical view of the utility model embodiment.
1---support; 2---independent foundation under column; 3---PVC sleeve pipe 3; 4---concrete cylindrical stake: 5---reinforcing cage; 6---pre-embedded steel slab; 7---reinforcing bar.
The specific embodiment
The job practices of cylinder pile foundation structure as shown in the figure is:
1. by foundation bearing capacity checking computations, overturning or slip resistance analysis checking computations and resistance to plucking checking computations, determine diameter, height and the buried depth of concrete cylindrical stake 4.
2. select the PVC sleeve pipe 3 of corresponding diameter and length for use, behind pore-forming, PVC sleeve pipe 3 is required to insert in the hole retaining wall according to buried depth, reinforcing cage 5 is placed in the PVC sleeve pipe 3, with reinforcing bar 7 fixing PVC sleeve pipes 3, toward PVC sleeve pipe 3 interior concretings.
3. treat that concreting near PVC sleeve pipe 3 tops the time, places PVC sleeve pipe 3 tops with the pre-embedded steel slab 6 that bolt is fixedly arranged, concreting is to PVC sleeve pipe 3 tops, and leveling pre-embedded steel slab 6 is namely finished the construction of cylinder pile foundation structure.
The cylinder pile foundation structure that obtains at last comprises PVC sleeve pipe 3 and is used for fixing reinforcing bar 7, is concrete cylindrical stake 4 and its inner reinforcing cage 5 that template forms with PVC sleeve pipe 3; The pre-embedded steel slab 6 that bolt is fixedly arranged is arranged at the top of concrete cylindrical stake 4.
Treat concrete cylindrical stake 4 maintenances to the designing requirement time, can also further save cost by removing PVC sleeve pipes 3 for the reinforcing bar 7 of fixing PVC sleeve pipe 3 and recycling and reusing, increase the benefit.
