The invention discloses an
airbag grout-block valve
pipe assembly for conveniently perforating and slip
casting construction. The
airbag grout-block valve
pipe assembly includes a slip
casting drill pipe, a rod body
grout-block valve, a rod body grout-out hole, a slip
casting valve pipe body, a grout-block
airbag, a slip casting pipe, an inflating pipe and a slip casting gun; the slip casting
drill pipe is provided with the rod body grout-out hole which is provided with the rod body grout-block valve, the slip casting
drill pipe is provided with the slip casting pipe body which is provided with the grout-block airbag, and the grout-block airbag forms an integral whole on the slip casting valve pipe body; and the front portion of the slip casting valve pipe body is connecting with the
slipcasting gun, the
tail portion of the slip casting valve pipe body is connected with the slip casting pipe, and the grout-block airbag is connected with the inflating pipe. According to the airbag grout-block valve pipe
assembly for the conveniently perforating and slip casting construction, the slip casting efficiency is greatly improved, compared with existing slip casting valve pipe products, the airbag grout-block valve pipe assembly has the advantages of higher grout-out speed and grout-out pressure, wider slip casting semi-
diameter, denser grout liquid filling effect and better grout liquid non-return performance under the same slip casting pressure, and the phenomenon of pipe plugging due to use of the grout liquid with quick set and early strength can be effectively prevented.
