Description

The anti-sinking of wind resistance square strengthens and increases steady type photovoltaic bracket foundation structure
Technical field
The utility model relates to Photovoltaic new energy applied technical field, is specifically related to a kind ofly to be applicable to that wind-force is comparatively large, the ground light overhead utility construction wind resistance square in district, anti-sinking strengthen and increase steady type photovoltaic bracket foundation structure saline and alkaline higher.
Background technology
Solar energy is the inexhaustible regenerative resources of a kind of mankind, and it has the multiple advantages such as spatter property, safety, popularity, persistence, abundance and potential economy, has important strategic position.Water energy, wind energy, tide energy can total amount all too little, can not meet human wants.Although the energy that nuclear fusion energy produces is huge, there is uncontrollability and security hidden trouble.Geothermal energy sees also have potentiality theoretically, but there is a technical difficult problem.So, solar energy be the mankind known, utilizable, unique clean and safe energy needed for human future can be solved.
Solar cell, as a kind of important Solar use means, is paid close attention to widely and is obtained development and application fast.Nearly ten years, photovoltaic application market obtains unprecedented flourish.The whole world increases installation amount rises to 2013 fast 37GW from the 293MW of 2000 photovoltaic year newly.NPD Solarbuzz estimates that solar energy demand in 2014 will reach 49GW.Ended for the end of the year 2013, the accumulative photovoltaic installation amount in the whole world is close to 140GW.
At present, global photovoltaic application market mostly is ground light overhead utility.Photovoltaic bracket basis mainly contains concrete foundation, pile foundation and continuous foundation three class.
Concrete foundation can be divided into independent seats basis and composite base basis according to structure.Concrete foundation can be divided into precast concrete foundation and direct concreting basis according to form of construction work.Precast concrete foundation has that intensity is good, precision is high, to features such as ground strong adaptabilities, be applicable to as geology is installed in beach, fish pond etc., this type of concrete foundation, generally with pre-embedded bolt or steel plate, is convenient to carry out bolt with photovoltaic bracket and is fixed or weld more.Direct pouring basis also has the plurality of advantages on concrete prefabricated basis, directly built support together with concreting by concrete, this mode eliminates pre-buried parts, build require high to the positioning accuracy request of support member, need positioning tool to complete.
Pile foundation can divide impact type ground pile foundation and pile foundation spirally, is divided into again pair upright post basics and single upright post basic by supporting way.Impact type ground pile foundation has that speed of application is fast, strong adaptability, cost performance are high, pile little by the restriction such as temperature in season is pulled out conveniently, do not affected recycling.Impact type pile erecting bed measured distance after, directly with pile driver, column is driven underground, convenient and swift, need in a pre-installation to do geology Soil K+adsorption, determine suitable depth of drive.Spiral pile strong adaptability, combine versatile and flexible, pull out conveniently by little, the pile of temperature restriction in season, do not affect the recycling of fabricating yard.When fabricating yard soil property is too hard, or rubble is too many, is driven underground at need, can adopts spiral pile by impact type pile.Spiral pile special mechanical equipment is screwed in underground.
It is firm that continuity basis has basis, is applicable to soft geology, wind resistance, strong shock resistance.But cost is higher.It is identical that continuous foundation and general concrete water underpin, and carry out concreting after first pre-embedded bolt or steel plate and produce continuous print concrete foundation, then support is placed in concrete foundation, fixes or weld with bolt.
At present, impact type pile and pile foundation spirally common basal form the most in ground light overhead utility.And the awful weather area comparatively large at some blast, snow load is too high, saline and alkaline is higher, owing to there being special requirement that are anticorrosive and high strength to photovoltaic bracket foundation structure, current photovoltaic bracket basis adopts the precast concrete foundation of pre-embedded bolt or steel plate more or directly concreting is basic.But, this type of basis because of the soft of soil or snow load excessive and cause sinking, because of the strength deficiency of concrete foundation and photovoltaic bracket connector, the distortion of photovoltaic bracket system when blast is larger, can be caused.For the difficult problem that this type of photovoltaic bracket foundation structure runs into, this patent provides a kind of and is suitable for that blast is excessive, snow load is too high, the wind resistance square in district, anti-sinking strengthen and increase steady type photovoltaic bracket foundation structure saline and alkaline higher.
