At present, a single-pile foundation is mostly adopted in a single-upright-column mode, the foundation resists upper load only by soil pressure provided by a soil layer into which a tubular pile enters, and as the size of a photovoltaic module is gradually increased, horizontal wind load borne by a single photovoltaic module is increased, so that higher requirements are provided for the horizontal bearing capacity and the pile body bending resistance of a photovoltaic support foundation. At present, one of the two most commonly used modes is to reduce the distance between piles, which means that more pipe piles need to be used, namely the total number of the pipe piles is increased, and the other mode is to use the pipe piles with higher strength, namely the cost of the pipe piles per meter is increased; both approaches are relatively costly.

Detailed Description

The utility model is described in detail below with reference to the accompanying drawings:

as shown in fig. 1, the utility model provides a photovoltaic pile-column integrated foundation support structure, which comprises a tubular pile 1, a hoop 2, a support 3 and a buttress 4. The anchor ear has two connections, between one connection and one buttress 4 a support 3 is provided. The anchor ear 2 is fixed on the pile body of the tubular pile 1 through a bolt, the upper part of the support 3 is connected with the anchor ear 2, and the lower part of the support is welded with the buttress 4 through an embedded part.

The anchor ear 2 is structured as shown in fig. 2, and is composed of a first half hoop 21, a second half hoop 22 and a first fastener 23, and the first half hoop 21 and the second half hoop 22 are spliced and fixed on the tubular pile 1 through the first fastener 23.

The structure of the first 21 and second 22 half-cuffs, see fig. 3-6. Two connections are located on the second half-hoop 22; the connecting part is provided with a bolt hole 221 for connecting with the second fastener 5; the support 3 is fixed to the hoop 2 by the second fastening member 5 mounted on the bolt hole 221.

The buttress 4 is a concrete pier, see fig. 7 and 8, and is composed of concrete 41, embedded steel bars 42 and embedded steel plates 43, wherein the embedded steel plates 43 are positioned on the surface of the concrete 41, and the embedded steel bars 42 are welded at the lower ends of the embedded steel plates 43. The bottom of the buttress is serrated.

The support 3 is a steel structure support, and the lower part of the support is welded on the embedded rigid plate 43 of the buttress.

When photovoltaic module received the wind load, superstructure will receive the load transmission for the tubular pile, and at this moment some load is shared through the staple bolt and is given the support, supports and transmits for the buttress through buttress top embedded part, is offset by the frictional force between buttress and the soil and the passive soil pressure that the soil produced the buttress, because the sawtooth structure of buttress bottom, the coefficient of friction between buttress and the soil will be greater than the coefficient of friction between concrete and the soil, consequently only need the concrete buttress of less volume can guarantee bearing capacity. The other part of load is offset by passive soil pressure generated by a soil layer into which the tubular pile enters, and due to the sharing effect of the supporting structure, the pile body bending moment of the tubular pile and the horizontal force required to be born are reduced to a certain extent, the tubular pile model with the lower pile body strength can meet the design requirement, and the soil penetration depth of the tubular pile can be reduced to a certain extent, so that the cost is saved and the manufacturing cost is reduced while the structural reliability is not changed;

the utility model supports the tubular pile on the original single pile foundation, improves the horizontal bearing capacity of the foundation, reduces the maximum bending moment borne by the pile body, thereby reducing the required penetration depth of the tubular pile and the strength requirement of the pile body, finally shortening the total meter number of the tubular pile and reducing the model number of the tubular pile without reducing the structural bearing capacity. The cost is reduced while the structural reliability is satisfied.
