The invention provides an independent node fabricated frame structure and a construction method. The method comprises the steps that the positions of prefabricated nodes are determined and placed, wherein a main beam steel reinforcement framework and a secondary beam steel reinforcement framework are mechanically connected between the prefabricated nodes; a main beam frame and a secondary beam frame are mounted below the main beam steel reinforcement framework and the secondary beam steel reinforcement framework correspondingly; concrete is poured into the main beam frame and the secondary beam frame; floor slabs are laid on a frame defined by the main beam frame and the secondary beam frame, a post-cast strip is reserved between every two adjacent span frame floor slabs, and concrete is cast in situ in the post-cast strips; column steel reinforcement frameworks are mounted on the prefabricated nodes; the column steel reinforcement frameworks are sleeved with column frames; a layer ofprefabricated nodes are mounted on the column steel reinforcement frameworks; and concrete is poured into the column frames, and a frame construction process is completed. According to frame construction, the prefabricated nodes serve as the center, and the construction process of site fabricated building nodes is omitted. The beam frames and the column frames play a role in positioning and serving as formworks, the processes of formwork dismounting and repeated utilization are avoided in construction, and the construction cost is greatly reduced.

The invention discloses a method for urgently blocking a river dam breach based on an array rocket drilling ground anchor. The method comprises the following specific steps that (1) the rocket anchor is launched, an anchor cable is connected with a shore fixed pile, and a 'rooting strongpoint' is formed at the dam breach; (2) steel mesh stone cage sets are slidably thrown through the rocket anchor cable, and a 'tower of strength' for dam breach blocking and repairing is rapidly formed; and (3) through an anchor dot array, steel mesh stone cages are slidably thrown and connected to form an 'expanding main body' for dam breach blocking and repairing. Precise arraying is conducted through laser guidance, meanwhile, anchor tools are triggered and expanded through sensing, the anchor tools are firstly fixedly arranged and then combined to increase the area, thus a preset anchor array is rapidly formed at the dam breach, and then the steel mesh stone cages are slidably thrown through a plurality of channels to construct a blocking and repairing main body. The technology is based on the high technology and adopts interdisciplinary innovation, the situation that military products are used for people is developed, the important technical problem of river treatment is solved, and wide application prospects and huge social and economic benefits are achieved.
