  • Jet Grouting Malcolm Drilling

    A drill rig advances a relatively small diameter (4-8 inches) jet grout tool to the bottom of the proposed treatment zone and injects fluid grout at high velocity. The drill tool is withdrawn and rotated at a constant rate as the grout erodes and mixes the surrounding soil to create a soil-cement column from the bottom elevation upwards.

  • A DSM WALL FOR EXCAVATION SUPPORT Geo

    2017-5-6 · Deep soil mixing (DSM) involves the use of an auger to mix in-situ soil with cement grout to create a soil-cement column. Steel beams are inserted within selected holes to offer reinforcement. The soil-cement columns are overlapped along the alignment to create a continuous soil-cement wall. The wall design considered construction aspects of the DSM process. The drilling equipment is built such

  • Drilling,Logging & Sampling at Contaminated Sites

    2018-12-6 · This document provides guidelines for drilling, sampling and describing soil from boreholes drilled to characterize contaminated sites. The information in this document provides a brief description of various drilling methods, soil sampling, and a summary of the Unified Soil Classification System (USCS) and American Society for Testing and

  • Behaviour of weak soils reinforced with soil cement

    2015-5-1 · In order to determine the undrained shear strength of the column, a sample of soil cement was prepared inside a Plexiglas tube with an inner diameter of 38 mm and a height of 76 mm to perform the Unconsolidated Undrained (UU) test. The installation of the soil–cement columns was conducted after completion of the consolidation process.

    Drilling Methods & Equipment Several different methods exist for advancing a steel casing or grout injection pipe to a desired design depth for compaction grouting.The differing techniques are typically dictated by soil conditions, project size, injection depth and access limitations.

  • Jet Grouting Casagrande Drilling and Foundation

    Jet Grouting is a modern, fast and effective method applied in soils and in weak rocks for the creation of deep foundation elements. With Jet Grouting, soil is mixed in site directly with the stabilizer (usually a water/ cement admixture) which is injected at very high pressure (300 Bar al least). The jet stream, coming out from the nozzles

  • Drilling Rig for Construction of SMWBored Pile

    SMW uses multi-shaft auger to drill soil in situ, meanwhile pumps cement grout from the tips of the augers into the drilled holes. After sufficient mixing of the grout, H-shaped steel or other types of steel are embedded into the columns before the soil-cement mixture hardened, forming a underground continuous wall with rigidity and intensity.
