The pivotal connection between the adapter ring 62 and the adapter bar 61 allows the adapter ring 62 to be changed in various inclination angles to facilitate the engagement between the guard rails, as shown in fig. 2 and 3. The metal connecting ring 61 is more corrosion-resistant and firmer, so that the service life of the guard rails is longer, and the connection between the guard rails is firmer.

The utility model provides a deep foundation pit edge-approaching guardrail which has the beneficial effects that: the bottom of the guard rail is provided with a protective net which can ventilate and prevent sundries such as rocks from falling into the foundation pit; the transverse plates connected in series on each spring can slide and rotate on the spring, the transverse plates are in a natural vertical state under the condition of normal no wind or small wind, and the transverse plates can rotate by taking the spring as an axis when the wind power is large so as to reduce the acting force of the wind on the protective guard and have better stability; the cross rod is inserted into the vertical pipe, the lower part of the vertical pipe is inserted into the base, and the vertical pipe and the base are fixed by the screw and the nut, so the protective guard is convenient to disassemble and assemble; the connecting rings are rotatably connected with the connecting rods, so that the directions of the connecting rings can be rotated, mutual connection among the connecting rings and cross connection at different angles are realized, and the connection among the guard rails can be twisted.
