Abstract

The utility model relates to a photovoltaic power station array pile base device, in particular to a photovoltaic power station array pile base, which has the technical scheme that the photovoltaic power station array pile base is characterized in that the pile base is in a cylindrical shape, three sections of threaded steel and a plurality of steel bars are pre-arranged in the pile base and are bended into triangular shapes to be bound into pile base keels for forming a pile base with concrete, and two to four screw rods are pre-arranged on the top of the pile base. The photovoltaic power station array pile base has the following advantages and effects that the photovoltaic power station array pile base provided by the utility model is different from the large-digging mode generally adopted in the prior art and belongs to the photovoltaic power station array pile base with a simple structure, small engineering quantity and low cost, a large number of pile base materials can be saved, in addition, the soil quality disturbance is small, an important effect is realized on the original ecological feature protection, and the ecological damage is also little.

Description

A kind of photovoltaic plant array pile foundation

Technical field

The utility model relates to a kind of photovoltaic plant array base apparatus, relates in particular to a kind of photovoltaic plant array pile foundation.

Background technology

Existing photovoltaic plant array foundation pile is built, and generally adopts the heavy excavation mode, and volume of earthwork is big; expend a large amount of basic materials, manpower and materials; engineering time length, complex structure, expense height destroy ecological environment, are not suitable for the requirement of country to ecological environmental protection.

Summary of the invention

The purpose of this utility model is for overcoming above-mentioned existing weak point; and proposed a kind of simple in structure; engineering quantity is little, expense is low, can save a large amount of pile foundation materials; and less to the soil property disturbance, to protecting ecological original looks, the less a kind of photovoltaic plant array pile foundation of environmental destruction.

The utility model adopts following technology case for achieving the above object: a kind of photovoltaic plant array pile foundation, it is characterized in that this pile foundation is cylindrical, being preset with three screw-thread steels and some bar bendings in pile foundation becomes triangle and is bundled into the pile foundation keel, constitute pile foundation with concrete, be preset with 2-4 root lead screw at the pile foundation top and form.

Advantage of the present utility model and effect: a kind of photovoltaic plant array pile foundation that the utility model provides, be different from and existing generally adopt the heavy excavation mode, be a kind of simple in structure, engineering quantity is little, expense is low, can save a large amount of pile foundation materials.And less to the soil property disturbance, played important function to protecting ecological original looks, also be the photovoltaic plant array pile foundation less to ecological disruption.

The specific embodiment

Shown in accompanying drawing 1-6, wherein: the 1st, pile foundation, the 2nd, keel, the 3rd, lead screw, the 4th, concrete.

A kind of photovoltaic plant array pile foundation of the present utility model, this pile foundation 1 is cylindrical, being preset with three screw-thread steels and some bar bendings in pile foundation becomes triangle and is bundled into pile foundation keel 2, constitutes pile foundations with concrete 4, is preset with 2-4 root lead screw 3 at the pile foundation top and forms.

Embodiment

Shown in Fig. 1-6, a kind of photovoltaic plant array pile foundation of the present utility model, this pile foundation is equidistantly uniform according to the support format array.

One, the array pile foundation adopts Reinforced Concrete Circular Cylinder shape basis, and the degree of depth is decided according to geological conditions, after the pile foundation round pool digs, and every coagulation heatable adobe sleeping platform surface brush bitumen treatment that directly contacts with underground.

Two, pile foundation 1 circular diameter is suitably adjusted the pile foundation diameter according to weight support frame.

Three, stake is cheated to circular, and putting into three screw-thread steels in the hole becomes pile foundation keel 2 by some reinforcing bars through being bent to the triangle binding, and these keel are put into the round pool that digs, and are through mixed concrete mortar perfusion, stand-by after solidifying.

Four, pile foundation 1 top is embedded with 2-4 root lead screw built-in fitting, and this lead screw 3 is connected and fixed with the solar bracket base.

Claims

1. photovoltaic plant array pile foundation, it is characterized in that this pile foundation (1) is cylindrical, being preset with three screw-thread steels and some bar bendings in pile foundation becomes triangle and is bundled into pile foundation keel (2), constitute pile foundation with concrete (4), be preset with 2-4 root lead screw (3) at the pile foundation top and form.
