Step 3, recharge forms water sealing consolidation body from gel material in Xiang Suoshu drilled pile.
Further, the drilling machine that circled round entirely by full-sleeve applies the drilled pile.
Further, in step 3, mode of the recharge from gel material in Xiang Suoshu drilled pile are as follows: the set of side extraction drilled pile
Tube edge recharge is from gel material.
Further, it is described from gel material be plain concrete or cement slurry.
Further, the method also includes: apply a row and the tangent drilling of the drilled pile again in drilled pile periphery
Interlocking pile is mutually twisted between hole-drilling interlocking pile, and first hole-drilling interlocking pile is also tangent with earlier diaphram wall, the last one
Hole-drilling interlocking pile is also tangent with later period diaphram wall；After the completion of hole-drilling interlocking pile applies, hole-drilling interlocking pile and drilled pile are removed
Between and the soil body or mudcake between hole-drilling interlocking pile, drilled pile and diaphram wall, then into the hole-drilling interlocking pile
Recharge is from gel material.
Further, the method also includes: after the completion of hole-drilling interlocking pile applies, remove hole-drilling interlocking pile and drilled pile it
Between and the soil body or mudcake between hole-drilling interlocking pile, drilled pile and diaphram wall, then into the hole-drilling interlocking pile return
It fills from gel material.
As another aspect of the present invention, a kind of cold seam waterproof construction of two phase of knuckle types diaphram wall, including folding are provided
It two phase of angle-style diaphram wall and is applied at the two phases diaphram wall dog-ear tangent with two phase diaphram walls
It is filled between drilled pile, the drilled pile and drilled pile and two phase diaphram walls from gel material.
Further, the structure further include in drilled pile periphery and the tangent row hole drilling interlocking pile of the drilled pile,
It is mutually twisted between hole-drilling interlocking pile, first hole-drilling interlocking pile is also tangent with earlier diaphram wall, the last one drilling is stung
It is also tangent with later period diaphram wall to close stake, between the hole-drilling interlocking pile, hole-drilling interlocking pile and drilled pile and hole-drilling interlocking
It is filled between stake, drilled pile and diaphram wall from gel material.
Beneficial effects of the present invention:
Since cast-in-situ bored pile stiffness by itself is big, perpendicularity deviation is small, it can effectively prevent that earlier diaphram wall is pre-buried to be connect
The even water burst of cold seam percolating water caused by head failure or perpendicularity difference, improves waterproof quality at cold seam, reduces engineering risk.
