Guiding and splicing construction method for recyclable foundation grouting guide pipe
The invention discloses a recyclable foundation grouting guide pipe guiding and splicing construction method. The method comprises the following construction steps that S1, a guiding base is buried; s2, drilling holes; s3, embedding a guide pipe; s4, after the Nth section of catheter is buried, the Nth section of catheter is fixed through a catheter temporary fixing plug pin, and the catheter temporary fixing plug pin is pulled out; s5, all the guide pipes are pushed into the hole positions; s6, grouting operation is conducted on the hole site, in the process, it is guaranteed that the guide pipe is located in the middle of the hole site through the guide base, and the periphery is filled and wrapped with grouting liquid; s7, when grouting is close to a guide pipe hole, the device is taken out; s8, after the grout in the guide pipe hole sinks, secondary grouting is conducted in time till the guide pipe hole is full; and S9, after the age is reached, performing test detection according to design requirements. By the adoption of the construction method, the inlet hole perpendicularity (or angle) of the guide hole can be guaranteed, temporary fixing of the guide pipe is provided for on-site splicing and welding of the ultra-long guide pipe, and the guide pipe construction is facilitated to form a standardized process.
本发明公开了一种可循环利用的地基注浆导管导向与拼接施工方法，包括以下施工步骤：S1：埋设导向基座；S2：钻孔；S3：埋设导管；S4：埋设第N节导管后，通过导管临时固定插销固定第N节导管，拔出导管临时固定插销；S5：全部导管推入孔位中；S6：孔位进行注浆作业，过程中通过导向基座，确保导管处于孔位的居中位置，周边被注浆液体填充包裹；S7：注浆接近导管洞口时，取出本装置；S8：待导管孔内浆液下沉后，及时进行二次注浆至饱满；S9：达到龄期后，按设计要求进行试验检测。采用本施工方法可以保证导孔的入孔垂直度(或角度)，为超长导管现场拼接施焊提供导管的临时固定，有助于导管施工形成标准化流程。
