(3) For the improvement of the soil nail, a nonmetal material is adopted, so that an underground barrier is not formed, for example, a full thread fiber resin rod body soil nail wall of a new development general company in China has the defects of high manufacturing cost and high construction difficulty, and the material is still buried underground to cause resource waste.
(4) The improvement of soil nails also adopts a construction method of recyclable friction type anchor rods for recycling soil nails, such as Zhanghong 'a recyclable soil nail reinforced bar structure' of Zhengzhou university, realizes the theoretically recyclable soil nails, and has the defects that the recycling is allowed only after the underground structure is built on site and when a foundation pit is backfilled, but the width of a fertilizer groove of the foundation pit is only about 1m, the soil nails with the length of 6-12 m cannot be recycled, and the manual recycling speed is slow, the cost is high and the danger is large.
