SMW Hydraulic Drilling Rig Diaphragm Wall Grab Three Mixing Power Head
Diaphragm Wall Grab Three Mixing Power Head Strength Of Cement - Soil Piles Method
SMW construction method construction principle:
As a technology for retaining soil and waterproof curtains for
foundation pits, the SMW method is also called column-type soil
cement wall method, which uses a multi-axis long auger drill to
drill a hole in the soil to a predetermined depth. The drill side
injects the cement slurry suitable for the engineering requirements
from the end of the drill bit and mixes with the original soil. SMW
special drilling rig is used, cement is used as a curing agent to
perform in-situ forced mixing with the foundation soil, and the
section steel is inserted to form a cement-soil "underground
continuous wall" wall after curing, making full use of the high
water resistance of the cement retaining wall and the
characteristics of the section steel Through the combined action of
the two, it is used as a foundation pit retaining and lateral
waterproof structure. When its enclosure function is completed, the
section steel can be pulled out and reused. To
The advantages of SMW construction method:
Compared with the traditional deep mixing pile construction method,
the SMW construction method uses different equipment and different
pile forming mechanism. The deep mixing pile adopts the traditional
single-shaft mixing rig. The cement slurry is injected and filled
in the gap of the original soil during construction. The new
three-shaft mixing rig adds high-pressure air when filling the
cement slurry. Undisturbed soil. The pile strength and pile
uniformity of the new three-axis drilling rig are significantly
better than those of the traditional single-axis drilling rig. Its
importance is that the parallelism and overlap between the two
adjacent piles and the pile are very good, ensuring excellent and
reliable Waterproof performance is also conducive to the insertion
and recovery of section steel and the traditional foundation pit
enclosure. To
Compared with the currently frequently used construction methods of
underground continuous walls and bored piles, the main features are
as follows:
(1) The water resistance is strong, which is conducive to the use
of pits without precipitation outside the pit;
(2) Small impact on surrounding buildings and pipelines;
(3) Noise, mud, vibration, etc. have little environmental
pollution;
(4) Can adapt to most stratums (especially soft soil areas);
(5) Short construction period;
(6) Low cost.
