1.1 HISTORICAL BACKGROUND OF GROUTING
The development and history
of compaction grouting over the last 30-40 years as been established by
many distinguished researcher, design engineer and design contractor.
Many technical papers are been published dealing physically with the
issues surround compaction grouting design such as: “compaction
grouting, 1973â€, “planning and performing compaction grouting†1974.
These and other important reference are the main stream basis of
knowledge for the highly specialize engineering and construction
technique know as compaction grouting. The compaction grout method as
some unique features which allow distinct advantages over other remedial
method of geo-technical construction. In many distances growth is the
only viable solution. Some of the advantages include: Economic: Many
time compaction grouting is the only feasible solution to foundation
settlement problems, other than demolishing the structure and
re-building with expensive deep foundation technique. Minimal
disturbance: During the grouting operation, destructure may remain
occupied and in service. Minimal risk: Compaction grouting offers
minimal risk of catastrophic structural failure while re-leveling
structure. Other are: Minimal geotechnical exploration, provide greater
support for structures, cost factor e.t.c.
1.2 AIM AND OBJECTIVE
1. To determine the nature of the sandy soil particles.
2. To determine the degree of the sandy soil compatibility.
3. To carry out the improvement of sandy soil through grouting.
4.
To carryout some laboratory test on sandy soil such as compaction test
California bearing ration (CBR) test, atterberg LIMIT test, liquid limit
test, Plastic limit test, sieve analysis test in comparing the
effectiveness of grouting system.
1.3 SCOPE OF THE
STUDY This research is focused on the quality and improvement of bearing
capacity of sandy soil by grouting.
1.4 LIMITATIONS OF THE STUDY The limitations of this study are:
TIME FACTOR: Limited time that does not permit to carryout many practical.
AREA OF STUDY: This project is limited the technical study of sandy soil properties.
