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.
