Photovoltaic power station base construction process achieved through sand falling under action of water

Abstract

A photovoltaic power station base construction process achieved through sand falling under the action of water includes the following steps that (A) according to the requirement of the specification of a photovoltaic assembly, a photovoltaic assembly base foundation is dug; (B) fine sand is poured onto a foundation sand layer for pavement, and a cofferdam is built through sand and soil on the basis of the fine sand; (C) water is injected into the cofferdam and then stands still, so that the fine sand falls under the action of scouring force of the water and self-gravity and becomes compact, and the water and the fine sand seep into the sand layer; (D) quality detection is carried out, if compactness does not meet the requirement, the step (C) is repeatedly carried out until the compactness meets the requirement, and if the compactness meets the requirement, the step (B) and the step (C) are repeatedly carried out until the sand reaches a designed height. According to the process, the structure is simple, construction is convenient to carry out, and the process is especially suitable for being used for manufacturing a photovoltaic power station base in a desert.

Description

technical field [0001] The invention belongs to the field of photovoltaic power station construction, and in particular relates to a photovoltaic power station foundation construction technique suitable for desert geology and fully utilizing the infiltration and solidification of water and sand to simplify the construction technique. Background technique [0002] At present, the excavation and deepening of the building of photovoltaic power station adopts the scheme of graded stone, and the construction requirements: 1. The sand and stone should be crushed stone, which should be well graded; 2. Layered paving; 3. The cushion cannot store water; 4. , and backfilling all use graded sand and gravel. For desert power stations, the geology is sand. If a graded scheme is used and crushed stone materials are used, the cost of material procurement will increase, and the difficulty of construction will increase, and the transportation in desert areas is extremely inconvenient, which w...

Problems solved by technology

[0003] In order to solve the above defects, meet the anti-overturning force and wind resistance requirements of the photovoltaic support on desert geology, and at the same time avoid the disadvantages of cost procurement, excessive transportation, increased cost, and construction difficulties, the present invention provides a photovoltaic Power station foundation construction technology, the foundation form can meet the anti-overturning force and wind resistance, effectively avoid the problems of excessive transportation volume and construction difficulties, and the operation is simple. By laying fine sand on the original sand layer, and then laying fine sand The upper cofferdam and water storage, the fine sand is self-falling and dense under the action of water, the gravel material is completely removed, the cost is reduced, and at the same time, the construction process is simple and the construction difficulty is reduced
