The invention provides a reinforced concrete structure deep hole steel bar planting construction method. The reinforced concrete structure deep hole steel bar planting construction method comprises the following steps that (1), the positions of foundation steel bars buried in a reinforced concrete structure are determined; (2), steel bars are planted and holes are drilled; (2.1), when contacting with the foundation steel bars, drilling is carried out to a designed depth, a large drill bit is replaced for supplementary drilling; (2.2) in the drilling process, when the foundation steel bars are exposed, the design interval of the foundation steel bars is determined according to a foundation construction drawing, the drilling position is deviated laterally, and drilling operation is carried out after the large drill bit is replaced; (3), steel bar embedding glue is poured into steel bar embedding holes by using a grouting device, a glue injection nozzle of the grouting device extends into the vicinity of the bottom of the steel bar embedding holes, and the glue injection nozzle of the grouting device is pulled out while the glue is injected; and (4), after the embedded steel bars are inserted into the bottoms of the embedded steel bar holes, it is ensured that the embedded steel bars are not disturbed for 24 hours at normal temperature, and the embedded steel bars are completed 48 hours later. By adopting the reinforced concrete structure deep hole steel bar planting construction method, the situation that the embedded steel bar holes need to be re-drilled or the foundation steel bars are damaged due to contact with the foundation steel bars in the conventional embedded steel bar pore-forming construction process can be avoided.
一种钢筋混凝土结构深孔植筋施工方法，包括以下步骤：1）确定钢筋混凝土结构内埋设的基础钢筋位置；2）进行植筋钻孔；2.1）与基础钢筋接触时，钻孔至设计深度后更换为大钻头后进行补钻；2.2）当钻孔过程中，发生基础钢筋暴露情况时，则根据基础施工图纸确定基础钢筋设计间距，并向侧向偏移打孔位置，更换为大钻头后进行钻孔作业；3）使用灌浆器向植筋孔内灌注入植筋胶，灌浆器的注胶咀伸入植筋孔的孔底附近，边注胶边抽出灌浆器的注胶咀；4）植筋钢筋插入植筋孔孔底后，常温下保证24小时不扰动，48小时后植筋完成。本发明采用上述方法，能够避免常规植筋造孔施工过程中，因与基础钢筋接触导致植筋孔需重钻或造成基础钢筋受损的情况发生。
