GROUND IMPROVEMENT TECHNIQUES

Introduction
The civil engineering projects are the main significance of a developed country.To fulfill all the project , grounds are required with their heavy bearing capacity.But in our INDIA it is a problem to find out good soil for civil engineering Works everywhere.So the knowledge of ground improvement techniques is the most important to the civil engineers.

METHODS  FOR  GROUND  IMPROVEMENT
Replacement of soil 
Precompression of soil
Densification of soil
Reinforcement of Techniques
Grouting techniques
Stabilization using admixture
Geo textiles
Electro osmosis method
Replacement of soil 
It is the oldest and simplest soil improvement method.This strategy is to just uncover the inadmissible soil and supplant them with compacted fill.This is a typical method to remediate issues with collapsible soils. Evacuation and substitution is by and large reasonable just over the ground water table.
Precompression of soil
It is especially useful in soft clayey and silty soils because the static weight of the fill causes them to consolidate, thus improving both settlement and strength properties. 
Pre-compression has the following advantages:
1. The method has a long track record of success.
2. Any grading contractor can perform the work.

3. The cost is comparatively low, so long as soil for preloading is readily available. 
Densification of soil
The strength and stiffness of the soil is higher when the particles are packed in a dense configuration.This is most effective for improving soil characteristics. 
This can be aprroachs in following ways:
1.VIBRO TECHNIQUES

2.DYNAMIC COMPACTION
Reinforcement of Techniques
stone columns are used to increase the shear strength beneath structures .
The method consists of forming vertical holes in ground which are filled with compacted crushed stone, gravel and sand or a mixture.
Grouting techniques

PERMEATION GROUTING
 Stopping leaks in below-grade structures 
Stopping leaks in below-grade utilities 
Excavating support of non-corrosive soils
JET GROUTING
Jet grouting uses a special pipe equipped with horizontal jets that inject grout into the soil at high pressure.Teesta dam is the example of get grouting.
Stabilization using admixture
SOIL STABILIZATION: It is the process of improving the engineering properties of soil by mixing some binding agents thus binding the soil particles . Soil stabilization is classified as 
1.Mechanical stabilization 

2.Chemical stabilization 
Geo textiles

Geotextiles are porous fabrics manufactured products and others such as polyester ,poly-ethylene, polypropylene and poly vinyl chloride, nylon, fiber glass and various mixtures of these. 
Electro osmosis method
The electro osmosis process can be used to increase the shear strength and reduce the compressibility of soft clayey and silty soils beneath foundation, electro osmosis  with or without electrochemical hardening can be considered only for special situations where the alternative of piling cannot be adopted. 
Note
Mainly soil improvement techniques can be divided in to four broad categories.
1 Densification methods hand-off on propensity of granular soils to densify when subjected to vibrations. Anyway there is a plausibility of harming neighboring structures and pipelines because of use of this strategy.
2.Reinforcement techniques introduce discrete inclusions that stiffen and strengthen a soil deposit.
3.Grouting techniques involve the injection of cementicious materials into the voids of the soil or into fractures of the soil. 
4. Now a days, geotextiles are extensively used for improving the soil conditions. These has multiple applications as they act as filters, reinforcement, separations..etc.












Rain Water Harvesting

Introduction
Rainwater harvesting  is an innovation utilized for gathering and putting away water from housetops, the land surface or shake catchments utilizing basic methods, for example, rooftop top rain water collecting strategy or surface rain water harvesting technique.
Need for rainwater harvesting 
There are many reasons but following are some of the ones.
To beneficiate water quality in aquifers.
To conserve surface water runoff during monsoon.
To reduce soil erosion
To inculcate a culture of water conservation.
Where can rainwater harvesting is used ?
Hilly areas where ground water table is low where it is not possible to extract ground water or have no other water sources.
In urban areas where water is expensive, for washing, and gardening and to prevent local flooding.
In public and commercial buildings with large use of water.
Ways of rainwater harvesting

Surface runoff rain water harvesting


source Deccan Chronicle
The problem 

World face the dual problem of...

  flood and drought




Uses/ Benefits of Rainwater Harvesting
Water collected from roof catchments usually is of acceptable quality for domestic purposes. Water supply (Domestic, Industrial & Agriculture) Water Saving,  ( as supplementary source) Flooding control,  Ground water recharging Improve quality of ground water.
Disadvantage
Disadvantages of rainwater harvesting technologies are mainly due to the limited supply and uncertainty of rainfall. 

This may make rainwater harvesting less attractive to some governmental agencies tasked with providing water supplies in developing countries.

The man who began his career as a lecturer in an engineering college appeared for the Engineering Services Examination (ESE) and joined the Indian Engineering Service (IES). He first proved his ability as an engineer when he was put in-charge of restoring a bridge that had been damaged by a cyclone. He executed the complete work within 46 days as against the six months allotted to this task. Recognized by the government for his brilliance, he was made the in-charge for planning and designing the Kolkata metro, the very first metro in India. The next several years saw him working with the single-minded conviction to improvise the public transport system in India. He had become such an invaluable asset to Indian Railways that the government let him know that his services would be required even after he retired from IES. Several national and international honors have been bestowed upon him for his pioneering works.

Private job or M.tech which is best career options for civil  freshers

If you are confused between Private job or M.tech which is best option for civil  freshers then read this blog i think its help you to taking decisions.
Simply tune in to your mind what it needs to state. On the off chance that you are occupied with development at that point go for a temporary worker side firm since you will take in a considerable measure as the examinations barely enable yourself to rehearse much practicals. Put in multi year or two in it as you'll have the capacity to know the advantages and disadvantages of being a structural architect and what is normal from you. at that point maybe go for a Masters Degree. it can either be a MBA or M.tech. It is dependably to better to have commonsense experience before the bosses since it enables you to comprehend the subject better and with most extreme intrigue. You'll have the capacity to prosper well. one of my friend said  for Mtech you require a decent college in light of the fact that doing it from different universities will be a total waste according to him. So first in the event that you haven't finished your 4 long stretches of designing take a stab at doing as a lot of specialized endorsement courses ,that will help you especially ahead on the grounds that those courses are being appeared in your resumes. Furthermore, your resume is the primary thing an enrollment specialist gets the opportunity to see. over all you will have an upgraded information.Private job or M.tech which is best career options for civil  freshers in last i think if you have option must join job for one or two years and face real life of civil engineers.
