Abstract

The utility model relates to a photovoltaic plant component bracket foundation for plateau Gobi sandy soil regions. A pre-embedded steel plate is pre-embedded in a filling pile foundation, and is fixed in the filling pile foundation through concrete poured in a form; the form is a PVC (polyvinyl chloride) pipe. As the photovoltaic plant component bracket foundation for plateau Gobi sandy soil regions provided by the utility model adopts the mode that the pre-embedded steel plate is fixed in the filling pile foundation through the concrete poured in the form and uses a small-sized filling pile foundation to replace the traditional stepped foundation, the excavation workload is greatly reduced, the working efficiency is improved, and the economic benefit and environment protection benefit are remarkable; and hole building by dry methods based on a rotary drilling rig is adopted at the initial stage of making the small-sized filling pile foundation, so that not only can the excavation speed be guaranteed but also the pile hole forming and sandy soil stability can be kept.

Description

Sandy soil area, Gobi desert, a kind of plateau photovoltaic power station component bracket basis
Technical field
The utility model relates to a kind of photovoltaic power station component bracket basis, the regional photovoltaic power station component bracket basis of Gobi desert, especially a kind of plateau sandy soil.
Background technology
Stratum, sandy soil area, Gobi desert, plateau generally is divided into 2 layers from top to down: Quaternary system Holocene series Sand-Accumulated Silt Sand layer, gravel layer lens.Foundation soil top, site district fine sand layer 1.0m is positioned at the seasonal frozen ground band, water content is lower, the frozen soil type is few freezing soil, the frost heave grade is the I level, and the frost heave classification is frost heave not, and seasonal frozen ground is little on the building foundation impact, this layer be loosely organized~and slightly close, low bearing capacity, compressive strain is large, should not use as natural ground; The following fine sand layer in tundra and gravelly sand lens, close in structure~closely knit, bearing capacity is relatively high, and engineering property is better, can be used as bearing stratum or subbase.Sandy soil area, Gobi desert physical features is more smooth, open, the bad geophysical phenomenon agensis such as landslide, unstable body, mud-rock flow, migrating dune, the suitable photovoltaic generation engineering of building.
The a series of special engineering geological problems on solar bracket basis, sandy soil area, bring certain difficulty for design, construction and the operation maintenance of this engineering, as the intensity on basis, upper dial, press down, topple stable etc., in order to ensure the photovoltaic plant safe operation, must adopt a kind of special bracket basis that is applicable to the sandy soil area.
Summary of the invention
Technical problem to be solved in the utility model is to provide sandy soil area, Gobi desert, a kind of plateau photovoltaic power station component bracket basis, adopt small-sized bored concrete pile foundation to replace traditional footing foundation, can greatly reduce the excavation workload, improve work efficiency, economic benefit and environmental benefit are obvious.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: the regional photovoltaic power station component bracket basis of Gobi desert, a kind of plateau sandy soil, pre-embedded steel slab is embedded in bored concrete pile foundation, and pre-embedded steel slab is fixed in bored concrete pile foundation by the concrete of pouring into a mould in template.
Template is pvc pipe.
Sandy soil area, Gobi desert, a kind of plateau photovoltaic power station component bracket basis that the utility model provides, owing to adopting pre-embedded steel slab to be fixed on mode in bored concrete pile foundation by the concrete of pouring into a mould in template, use small-sized bored concrete pile foundation to replace traditional footing foundation, can greatly reduce the excavation workload, improve work efficiency, economic benefit and environmental benefit are obvious; This small-sized bored concrete pile foundation making initial stage is adopted rotary drilling rig dry method pore-forming, both can guarantee a rate of advance, can keep again a hole forming and sandy soil stable.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is top view of the present utility model.
The specific embodiment
As shown in Figure 1, the regional photovoltaic power station component bracket basis of Gobi desert, a kind of plateau sandy soil, pre-embedded steel slab 1 is embedded in bored concrete pile foundation 3, and pre-embedded steel slab 1 is fixed in bored concrete pile foundation 3 by the concrete of cast in template 2.
Template 2 is pvc pipe.
Utilize the rotary drilling rig dry method to revolve to scrape out the hole 1 pre-embedded steel slab 1 is embedded in bored concrete pile foundation 3, utilize 250mm diameter pvc pipe as the template one-time-concreting moulding make sandy soil area, Gobi desert, plateau photovoltaic power station component bracket basis.
