Grouting pipe
The invention discloses a grouting pipe. The grouting pipe comprises a conical terminal and a first grouting pipe body, wherein one end of the first grouting pipe body is coaxially and fixedly connected with the conical terminal, a plurality of grout outlets are distributed in the pipe wall of the first grouting pipe body, the end, not connected with the conical terminal, of the first grouting pipe body is connected with a second grouting pipe body coaxial with the first grouting pipe body, and the diameter of the second grouting pipe body is larger than the diameter of the first grouting pipebody. By means of the structure, soft soil grouting can also be blocked by the second grouting pipe body when entering the rear-section operation, and the grouting effect is improved.
本发明公开了一种注浆管，包括锥形端子、第一灌浆管，所述第一灌浆管一端与锥形端子同轴线固定连接，第一灌浆管的管壁上分布有若干出浆孔，所述第一灌浆管未与锥形端子连接的一端连接有与其同轴线的第二灌浆管，所述第二灌浆管的直径大于第一灌浆管直径。通过上述结构，使得软土灌浆在进入后段作业时也能够被第二灌浆管所封堵，进而提升灌浆的效果。
