Manual drilling technologies have the potential to enhance water access by providing a low cost drinking water alternative for communities in low and middle income countries. This paper provides an overview of the main successes and challenges experienced by manual boreholes in the last two decades. A review of the existing methods is provided, discussing their advantages and disadvantages and comparing their potential against alternatives such as excavated wells and mechanized boreholes. Manual boreholes are found to be a competitive solution in relatively soft rocks, such as unconsolidated sediments and weathered materials, as well as and in hydrogeological settings characterized by moderately shallow water tables. Ensuring professional workmanship, the development of regulatory frameworks, protection against groundwater pollution and standards for quality assurance rank among the main challenges for the future.

  • Soil Plugging of Open-Ended Piles During Impact Driving in Cohesion-Less Soil
    Soil Plugging of Open-Ended Piles During Impact Driving in Cohesion-less Soil VICTOR KARLOWSKIS Master of Science Thesis Stockholm, Sweden 2014 © Victor Karlowskis 2014 Master of Science thesis 14/13 Royal Institute of Technology (KTH) Department of Civil and Architectural Engineering Division of Soil and Rock Mechanics ABSTRACT Abstract During impact driving of open-ended piles through cohesion-less soil the internal soil column may mobilize enough internal shaft resistance to prevent new soil from entering the pile. This phenomena, referred to as soil plugging, changes the driving characteristics of the open-ended pile to that of a closed-ended, full displacement pile. If the plugging behavior is not correctly understood, the result is often that unnecessarily powerful and costly hammers are used because of high predicted driving resistance or that the pile plugs unexpectedly such that the hammer cannot achieve further penetration. Today the user is generally required to model the pile response on the basis of a plugged or unplugged pile, indicating a need to be able to evaluate soil plugging prior to performing the drivability analysis and before using the results as basis for decision. This MSc. thesis focuses on soil plugging during impact driving of open-ended piles in cohesion-less soil and aims to contribute to the understanding of this area by evaluating models for predicting soil plugging and driving resistance of open-ended piles. Evaluation was done on the basis of known soil plugging mechanisms and practical aspects of pile driving. Two recently published models, one for predicting the likelihood of plugging and the other for predicting the driving resistance of open-ended piles, were compared to existing models.

  • Newmark Sliding Block Model for Predicting the Seismic Performance of MARK Vegetated Slopes ⁎ T
    Soil Dynamics and Earthquake Engineering 101 (2017) 27–40 Contents lists available at ScienceDirect Soil Dynamics and Earthquake Engineering journal homepage: www.elsevier.com/locate/soildyn Newmark sliding block model for predicting the seismic performance of MARK vegetated slopes ⁎ T. Liang, J.A. Knappett ARTICLE INFO ABSTRACT Keywords: This paper presents a simplified procedure for predicting the seismic slip of a vegetated slope. This is important Analytical modelling for more precise estimation of the hazard associated with seismic landslip of naturally vegetated slopes, and also Centrifuge modelling as a design tool for determining performance improvement when planting is to be used as a protective measure. Dynamics The analysis procedure consists of two main components. Firstly, Discontinuity Layout Optimisation (DLO) Earthquakes analysis is used to determine the critical seismic slope failure mechanism and estimate the corresponding yield Sand acceleration of a given slope. In DLO analysis, a modified rigid perfectly plastic (Mohr–Coulomb) model is Slopes Vegetation employed to approximate small permanent deformations which may accrue in non-associative materials when Ecological Engineering subjected to ground motions with relatively low peak ground acceleration. The contribution of the vegetation to enhancing the yield acceleration is obtained via subtraction of the fallow slope yield acceleration. The second stage of the analysis incorporates the vegetation contribution to the slope's yield acceleration from DLO into modified limit equilibrium equations to further account for the geometric hardening of the slope under in- creasing soil movement. Thereby, the method can predict the permanent settlement at the crest of the slope via a slip-dependent Newmark sliding block approach.

  • Section 6D-1 Embankment Construction
    6D-1 Design Manual Chapter 6 - Geotechnical 6D - Embankment Construction Embankment Construction A. General Information Quality embankment construction is required to maintain smooth-riding pavements and to provide slope stability. Proper selection of soil, adequate moisture control, and uniform compaction are required for a quality embankment. Problems resulting from poor embankment construction have occasionally resulted in slope stability problems that encroach on private property and damage drainage structures. Also, pavement roughness can result from non-uniform support. The costs for remediation of such failures are high. Soils available for embankment construction in Iowa generally range from A-4 soils (ML, OL), which are very fine sands and silts that are subject to frost heave, to A-6 and A-7 soils (CL, OH, MH, CG), which predominate across the state. The A-6 and A-7 groups include shrink/swell clayey soils. In general, these soils rate from poor to fair in suitability as subgrade soils. Because of their abundance, economics dictate that these soils must be used on the projects even though they exhibit shrink/swell properties. Because these are marginal soils, it is critical that the embankments be placed with proper compaction and moisture content, and in some cases, stabilization (see Section 6H-1 - Foundation Improvement and Stabilization). Soils for embankment projects are identified during the exploration phase of the construction process. Borings are taken periodically along the proposed route and at potential borrow pits. The soils are tested to determine their engineering properties. Atterberg limits are determined and in-situ moisture and density are compared to standard Proctor values.

  • Borehole Drilling in Sedimentary Rocks
    MARCH 2015 PRELIMINARY ASSESSMENTS – PHASE 2 Borehole Drilling in Sedimentary Rocks Safety is the first consideration in finding a site for a deep geological repository for Canada’s used nuclear fuel. Between 2012 and 2014, the NWMO used available geoscientific information to begin the process of learning about the geology of potential siting areas. These Phase 1 desktop studies were used to understand the regional geology and sedimentary sequence in the Bruce area and identify whether communities had the potential to satisfy the NWMO’s geoscientific site evaluation factors. The results of these desktop studies are available online, at www.nwmo.ca and the websites of local community liaison committees, and in NWMO community offices. For sedimentary rocks, the next phase of preliminary assessments include a series of geoscientific field studies such as observing general geological features, borehole drilling, and 2D-seismic surveys. Field studies will initially be conducted to advance understanding of the general geology in each community. These would be followed by more detailed studies, several years in the future, to understand the geology of potential repository sites identified through technical studies and discussions with the communities. The scope, location, and timing of field studies will be developed in collaboration with communities. Preliminary Assessments – Phase 2 / Borehole Drilling in Sedimentary Rocks 1 Borehole Drilling and Testing Borehole drilling and testing provides information about the underlying rock layers, including their geological, hydrogeological and hydrogeochemical characteristics. Activities during drilling will initially include the collection of continuous rock core that will be logged and then transported to a core storage facility.
