Due to the fact that the through type foundation pit is a whole foundation pit, a civil foundation between original foundation pits does not need to be excavated, damage to electrical connection lines between the original foundation pits is avoided, the reconstruction cost is saved, and the construction period is shortened.

A distributed data storage method, control device and system, the method comprising: dividing data to be stored into m2 data blocks A (101); according to B generating a first checking block set C (102); wherein D; according to E generating a second checking block set F corresponding to the data to be stored; according to G generating a third checking block set H corresponding to the data to be stored; and respectively sending the m2 data blocks and 2m + 1 checking blocks to different storage devices and storing the same therein (105). Since each checking block is linearly associated with m data blocks, and the data blocks and checking blocks are respectively stored in different storage devices, multiple failed blocks can be restored with a reduced recovery cost.
