The utility model relates to a channel pipe network guarded body used for the slope protection and drainage and soil fixation of slope collapse. The channel pipe network guarded body is likely to be shaped and produced, and is likely to be combined, assembled and built in the wild. The aim of the channel pipe network guarded body provided by the utility model is realized by the following technical schemes: the channel pipe network guarded body used for the slope protection and drainage and soil fixation of the slope collapse comprises an upper catchwater, a plurality of middle horizontal headrace channels, a lower drainage ditch and a plurality of vertical drainage pipes, wherein the upper catchwater is arranged at the top of a slope, the plurality of middle horizontal headrace channels are sequentially and intermittently arranged downwards from the top of the slope, the lower drainage ditch is arranged at the bottom of the slope and the plurality of vertical drainage pipes are intermittently arranged on a slope surface in parallel; the upper and lower ends of the plurality of vertical drainage pipes are communicated with the upper catchwater and the lower drainage ditch, and each vertical drainage pipe is sequentially communicated with the plurality of middle horizontal headrace channels from top to bottom.
