The second guardrail unit 13 is opposite to the first guardrail unit 12 at intervals, and the protective cross bar 11 is connected between the first guardrail unit 12 and the second guardrail unit 13.

With continued reference to fig. 2 and fig. 3, each of the first guardrail unit 12 and the second guardrail unit 13 includes a fixing base 14, a guardrail body 15, a fastener 16 and a fastening fitting 17, the fixing base 14 is formed with a receptacle 141 and a via hole which are communicated with each other, one end of the guardrail body 15 is detachably inserted into the receptacle 141, the fastening fitting 17 is inserted into the via hole for fixing, the fastener 16 is movably inserted into the fastening fitting 17 and can extend into the receptacle 141, and the fastener 16 can lock or release the guardrail body 15.

The guardrail device of above-mentioned scheme is used for equipping in subway construction operation, specifically is used for enclosing the periphery of establishing at the foundation ditch and plays the safety protection effect, prevents that constructor from taking place the incident emergence of unexpected drop pit. Specifically, the barrier module 10 may be directly installed on the outer circumferential ground of the foundation pit alone as a minimum constituent unit of the barrier device. When the foundation pit is installed, the fixed base 14 is fixedly installed on the bottom surface of the periphery of the foundation pit, and the fixed base 14 is kept still; then one end of the guardrail body 15 is inserted into the insertion hole 141 on the fixed base 14, so as to realize the pre-assembly of the two; finally, the fastener 16 penetrates through the fastening fitting piece 17 and penetrates through the top column guardrail body 15, so that the guardrail body 15 is assembled and fixed with the fixed base 14, and under the working action of the first guardrail unit 12, the second guardrail unit 13 and the protective cross rod 11, a blocking and protecting effect can be formed on constructors outside a foundation pit, and the pit falling accident is prevented. And when the dregs in the foundation pit need to be transported out or the foundation pit is monitored, the fastener 16 only needs to be loosened, the fastener 16 releases the guardrail body 15, the guardrail body 15 can be directly pulled away from the fixed base 14, and the fixed base 14 is still fixed on the ground at the moment.
