The invention provides a combined type road guarding guardrail. The combined type road guarding guardrail comprises a protecting fence structure, mobile base structures, anti-colliding buffer bucket structures, rod grooves, fastening bolts, light absorption band structures, an LED warning device and an indicating lamp device, wherein the protecting fence structure is welded to the upper part of the mobile base structures; and the anti-colliding buffer bucket structures are mounted on the inner side of the lower part of the protecting fence structure. According to the combined type road guarding guardrail disclosed by the invention, a protecting net is connected to an inserting groove in an inserting manner, so that combination of the guardrail is facilitated, and disassembly of the guardrail is convenient; a display screen is a flexible display screen, and a first accumulator is a flexible accumulator, so that while not in use, the display screen and the first accumulator are convenient to wind on a supporting column, and occupied space is reduced; the nap light absorption band structures are arranged, so that the situation that the illuminating effect of vehicle lamps to an opposite lane in nighttime can be reduced is facilitated; and buffer grooves, bottom wheels, U-shaped frames and buffer springs are arranged, so that each bottom wheel can be ejected from the correspondingbuffer groove, moving the guardrail is facilitated, and the using functions are increased.
