Brinton, Flowmole Corporation HIGHLIGHT SUMMARY On the basis of a preliminary evaluation, it was determined that a high degree of variation in specifica- tions for horizontal earth boring, pipe jacking, and utility tunneling projects exists across the United States. It was also recognized that many designers and highway department representatives were not familiar with current methods, materials, and equipment being utilized. Since the contract documents, detailed plans, and specifications are the primary instruments of commu- nication for the contractor, then it is understandable why "incomplete, inaccurate, and faulty construction specifications often result in a large number of field problems " [55]. Designers and highway depart- ments have a professional responsibility to insure that their specifications are accurate and complete. This report is a result of in-depth research into the development of specifications for the rapidly evolving area of trenchless excavation construction (TEC). A summary description of the various methods, equipment, and materials commonly utilized in the United States is provided. The design principles and practices for various conditions and materials are presented. Recommended guidelines and specifications have been developed and are presented in this report.

  • Boring Methods of Exploration [ Section 2.1 : Different Types of of Boring Methods ]
    Module 1 : Site Exploration and Geotechnical Investigation Lecture 2 : Boring Methods of Exploration [ Section 2.1 : Different Types of of Boring Methods ] Objectives In this section you will learn the following Displacement borings Wash boring Auger boring Rotary drilling Percussion drilling Continuous sampling Module 1 : Site Exploration and Geotechnical Investigation Lecture 2 : Boring Methods of Exploration [ Section 2.1 : Different Types of of Boring Methods ] Boring methods of exploration The boring methods are used for exploration at greater depths where direct methods fail. These provide both disturbed as well as undisturbed samples depending upon the method of boring. In selecting the boring method for a particular job, consideration should be made for the following: The materials to be encountered and the relative efficiency of the various boring methods in such materials. The available facility and accuracy with which changes in the soil and ground water conditions can be determined. Possible disturbance of the material to be sampled. The different types of boring methods are : 1. Displacement boring. 2. Wash boring. 3. Auger boring. 4. Rotary drilling. 5. Percussion drilling. 6. Continuous sampling. Module 1 : Site Exploration and Geotechnical Investigation Lecture 2 : Boring Methods of Exploration [ Section 2.1 : Different Types of of Boring Methods ] 1. Displacement borings It is combined method of sampling & boring operation. Closed bottom sampler, slit cup, or piston type is forced in to the ground up to the desired depth. Then the sampler is detached from soil below it, by rotating the piston, & finally the piston is released or withdrawn. The sampler is then again forced further down & sample is taken.

Gallardo 1,2,*, Atsunao Marui 1 1AIST, Geological Survey of Japan, Quintessa Japan, Yokohama 220-6007 2Hytec Co. Yodogawa-ku, Miyahara 2-11-9, Osaka 532-0003, Japan *Corresponding author. A. H. Gallardo. E-mail: [email protected] Tel/Fax: +81-29-861-3684 ABSTRACT Hydraulic characteristics of sediments were investigated at J-PARC for the purpose of site characterization in relation with the construction of Japan’s largest proton-accelerator. A total of 340 samples extracted from 9 exploratory wells were examined by standard laboratory tests and complemented with statistical analyses to quantitatively determine the main terrain attributes. Two main hydro-geological units were recognized, although a number of embedded layers defined a multilevel aquifer. Grain-size distribution derived from sieve analysis and the coefficient of uniformity showed that soils are poorly sorted. On the other hand, hydraulic conductivity was measured by a number of parameters such as a log-normal distribution. Conductivity was also predicted by empirical formulas, yielding values up to three orders of magnitude higher. Discrepancies were explained in terms of soil anisotropy and intrinsic differences in the calculation methods. Based on the Shepherd’s approach, a power relationship between permeability and grain size was found at 2 wells. Hydraulic conductivity was also correlated to porosity. However, this interdependence was not systematic and therefore, properties at many parts of the profile were considered to be randomly distributed.

The intended audience is our drilling staff and field geology personnel involved with collecting the data. It also may be of interest to our engineering staff who interpret the data. There are many misconceptions regarding the test. This paper discusses - in plain terms - the significant aspects of the test and the pitfalls that can occur. Reclamation uses the SPT to evaluate the earthquake liquefaction potential of soils under our dams. These determinations are very critical and the decisions that are made affect the lives of people downstream. The data you generate will be used to decide if multi-million dollar modifications are required for these structures. Reclamation uses the Earth Manual procedure USBR 7015 to run the test - and if you haven’t read it you shouldn’t run the test. These procedures are boring and only discuss the mechanics of the test. This document provides background on various factors involved in the testing. Liquefaction is the process where water pressure builds up in granular soils during an earthquake. Soils which are most susceptible to liquefaction are “cohesionless” soils, primarily, clean sands and gravels (GP, SP, GW, SW, GP-GM, SP-SM) and silty sands and gravels (SM, GM).

  • Not-So-Boring Geology an Introduction to Borehole Geophysical Logging
    Not-So-Boring Geology An Introduction to Borehole Geophysical Logging Geologists have a choice of methods to use when they want to see what is underground. Borehole geophysical logging is the process of viewing, collecting, analyzing, and interpreting the data from boreholes. Borehole geophysics is the study of geologic (rock) and hydrologic (water) information of the shallow earth. Boreholes provide a way to view rock, water, and other materials, as well as physically obtain samples. There are numerous tools that scientists can use to obtain information from boreholes. In this exercise, you will learn about different kinds of tools used in borehole geophysical logging, what they do, and what information they provide. Then you will “read” real geophysical logs and put together what you have learned by answering some questions. What is borehole geophysical logging? First, what is a borehole? Essentially, a borehole is a cylindrical, open space created in the ground by a drilling rig. Boreholes can be as short as a few feet deep or as much as thousands of feet deep. They can be drilled at any angle but those for basic study are usually vertical. Boreholes can simply be open holes (when drilled in solid rock). A metal pipe the same diameter of the borehole – known as casing – can be inserted at least a few feet into a rock borehole to support the near-surface area of the hole. When a borehole is drilled in sand or other weak material it may be lined with casing, which prevents the hole from caving in. Wells that have already been drilled into the ground to extract or test water are convenient and often used for borehole studies.

A recent paper (Allen, 1974) noted that several vents and lava tubes on the west side of the Portland Hi lis represented the westernmost group of large Plio-Pleistocene centers of volcanic activity in the Northwest.
