[0012]The present invention will be further described below in conjunction with the drawings and specific embodiments.
[0013]The invention will be described below in conjunction with the backfilling of the ceramsite layer of the molten salt cold tank of the Dubai 950MW solar-thermal photovoltaic hybrid power station. The base radius of the molten salt cold tank of Dubai 950MW solar thermal photovoltaic hybrid power station is 22.5m, and the inside is successively graded sand and ceramsite (the thickness is 1.5m, and the area is about 1600m).2), gravel layer.
[0014]The ceramsite used in the invention has a particle size of not more than 20mm and a density of 340kg / m3, The compressibility of the ceramsite soil layer is 13%-17%. In order to achieve the required compression rate, compaction of ceramsite soil requires a lot of time and manpower and machinery investment. If the compression rate is too large, such as greater than 17%, the ceramsite soil will be damaged; if the compression ra...
