In the building construction, when the structure is reinforced or embedded iron parts are leaked and embedded, structural steel bars are required to be embedded on a reinforced concrete structure, and the steel plates and the embedded steel bars are welded or connected through bolts, so that the steel plates and the reinforced concrete structure are firmly connected.

In the prior art, a common method for planting reinforcing steel bars adopts chemical glue as a filling material to plant the reinforcing steel bars, and the basic process is that the side part of the reinforced concrete meeting the age requirement is drilled, reinforcing steel bars are placed in the drilled holes, and then the chemical bonding glue is injected under pressure, so that the implanted reinforcing steel bars and the reinforced concrete are effectively connected. However, in the above method, the chemical glue with flow plasticity has adverse effects on environment and vision, and the chemical glue has poor durability and poor reliability. Moreover, due to the reasons of construction, formula and the like, in practical construction application, most of the adopted chemical glue needs to adopt imported products, and the price is high; in addition, under the working condition of vertical bar planting, a method for adopting high-strength cement grouting material as bar planting filler is available at present, specifically, vertical drilling is firstly carried out, then steel bars are placed in the drilled holes, then the high-strength cement grouting material is injected, and the flow property and the gravity action of the high-strength grouting material are utilized to ensure that the bar planting is reliably connected with the reinforced concrete structure.

However, the method of using the high-strength cement grouting material for bar planting cannot be applied to horizontal bar planting, because when the high-strength cement grouting material is injected in the horizontal direction, the high-strength cement grouting material cannot be densely filled in the bar planting holes due to the fluidity of the high-strength cement grouting material; and the implanted screw rod is easy to sink below the horizontal hole under the action of gravity, and the bond stress formed by the implanted screw rod and the injected high-strength cement grouting material is poor, so that firm connection cannot be formed.
