The invention discloses an implementation system and method for improving the continuous collapse resistance of a spatial grid structure. The system includes a plurality of center nodes, a first connecting pipe is arranged between every two adjacent center joints, lining pipes are arranged on all the center joints, first limiting blocks are arranged on the first connecting pipes, second limiting blocks are arranged on the lining pipes, the first limiting blocks are matched with the second limiting blocks. The system and the method can effectively improve the continuous collapse resistance of the spatial grid structure.
