Civil Project Abstract Secant Pile Construction Technique

Civil Project Abstract Secant Pile Construction Technique:Over the last few decades construction of retaining walls in urban areas has grown significantly, as a result of territorial and economical development of the cities. In most cases, retaining walls are deep structures with the existence of groundwater level because urban areas are often at a few meters above sea level. Furthermore, construction of retaining walls in cities, introduce special problems as a result of being directly in touch with urban elements and citizens.

civil-project-abstract-secant-pile-construction-techniqueIn situ pile retaining walls are very popular due to their availability and practicability. There are different types of pile walls contiguous (intermittent) bored pile construction, (spacing between the piles is greater that the diameter of piles).

In these conditions, for deep borings and with the existence of groundwater level, diaphragm walls and secant pile walls are the only feasible retaining walls in urban areas. Secant pile walls are usually used in hard ground, where it is not possible to install diaphragm walls, and in rocks, and it is technically possible to install secant pile walls in a extensive range of grounds.

Advantages and Disadvantages:

Noise: comparatively secant piles methods are more adaptable. Wall plan geometry: As site values increase, the pressure to use all available space within basements has become intense. Sites are often sandwiched between existing buildings, and walls are placed in close proximity to adjacent structures or roads.

The main disadvantages of secant pile walls are:

1. Verticality tolerances may be hard to achieve for deep piles.

2. Total waterproofing is very difficult to obtain in joints.

3. Increased cost compared to sheet pile walls.

Conclusion:

For temporary works, a hard-soft secant constitutes a perfectly satisfactory structure. For permanent structures the suitability of the technique demands critical evaluation in the particular site circumstances and structural requirements. Cased secant construction methods provide a high degree of security when working in granular soils adjacent to heavily loaded foundations or adjacent structures. Hydraulic diaphragm wall cutters are high production machines and require a large site, both to work efficiently and for their related service plant and back up facilities.

Safe Water Technologies Civil Project Report

This Safe Water Technologies Civil Project Report is about Safe Water Technologies. Now days, technologies are developing and there are many industries are introduced. Though the technologies are developing, however water also getting polluted with these industries. Hence, Safe Water Technologies are required to protect the water.

Water everywhere is increasingly being contaminated from numerous sources and this, especially in drinking waters is a major concern, due to the associated health hazards. The most common contaminants being suspended matter, mud, silt, algae, bacteria and other pathogens. Besides large bulk processing systems for industry, Safe Water in India also has special focus on small and medium water supply needs.

Solutions are offered for treatment of Municipal Waters, Surface Waters, Open and Tube Well Waters including source waters from streams, rivers, ponds and lakes for drinking water for Residences, Housing Colonies, Resorts, Villages, and Small Towns. Today, more than 1.1 billion people lack access to safe drinking water and 2.6 billion people have no access to basic sanitation. In most industrialized countries, access to safe drinking water is nearly universal, and is often taken for granted. This access has come as the result of massive public expenditures, though now more and more water supply agencies are being privatized.

Three main sources of water can be considered as substitutes for contaminated water: groundwater, rainwater, and surface water. Much has been written about these sources, so this chapter offers only a brief review, with key references.• Groundwater is largely free from harmful bacteria and fecal contamination, though a poorly designed or constructed well can become contaminated from surface water. To prevent this, wells should be grouted around the borehole, and finished at the surface with a concrete platform, with good drainage away from the well.

Conclusion:

Thus, we can say that Safe Water Technologies has to be used protecting atmosphere and water pollution. Safe Water Technologies also protect human for diseases. Government has to supply the pure water for the poorest people in developing countries.

Retrofitting Of Rc Beams With Externally Bonded Simcon Laminates

This Retrofitting Of Rc Beams With Externally Bonded Simcon Laminates project report presents the results of experimental studies concerning the flexural strengthening of RC beams using externally bonded Slurry Infiltrated Mat concrete (SIMCON) laminates. A total of four reinforced concrete beams were cast and tested in the laboratory over an effective span of 3000 mm. Three beams were strengthened with bonded SIMCON laminate at the bottom under virgin condition and tested until failure; the remaining one beam was used as control specimen. Static responses of all the beams were evaluated in terms of strength, stiffness, ductility ratio, energy absorption capacity factor, compositeness between laminate and concrete, and the associated failure modes.

retrofitting-of-rc-beams-with-externally-bonded-simcon-laminatesComparison was made between the Control specimen and strengthened beam. The results show that the strengthened beams exhibit increased flexural strength, enhanced flexural stiffness, and composite action until failure. The cost of civil infrastructure constitutes a major portion of the national wealth. The rapid deterioration of reinforced concrete structures has thus created an urgent need for the development cost-effective methods for repair, retrofit and new construction.

As the number of civil infrastructure systems increases worldwide, the number of deteriorated buildings and structures also increases. Complete replacement is likely to be an increasing financial burden and might certainly be a waste of natural resources if upgrading or strengthening is a viable alternative.

Conclusion:

SIMCON laminates properly bonded to the tension face of RC beams can enhance the flexural strength substantially. The strengthened beams exhibit an increase in flexural strength of 45.0% as compared to the Control beam (CB1). At any given load level, the deflections are reduced significantly thereby increasing the stiffness for the strengthened beams. A flexible epoxy system will ensure that the bond line does not break before failure and participate fully in the structural resistance of the strengthened beams.

Real Time Automatic Irrigation System Project Report

This Real Time Automatic Irrigation System Project Report is about the Real Time Automatic Irrigation System. The report consists of Introduction, Block Diagram, Interfaces, Soil Moisture Sensor, Solenoid Valve, Relays. The continuous increasing demand of food requires the rapid improvement in food production technology. In a country like India, where the economy is mainly based on agriculture and the climatic conditions are isotropic, still we are not able to make full use of agricultural resources. The main reason is the lack of rains & scarcity of land reservoir water. 

real-time-automatic-irrigation-system-project-reportThe continuous extraction of water from earth is reducing the water level due to which lot of land is coming slowly in the zones of un-irrigated land. Another very important reason of this is due to unplanned use of water due to which a significant amount of water goes to waste. Agriculture is the oldest occupation in the world. We are unable to make full use of agricultural resources. The main reason is the lack of rains and scarcity of land reservoir water. This project helps in time saving and removal of human error in adjusting available soil moisture levels. The goal of this project is to automate the irrigation system with the help of wireless communication. Before having an automatic irrigation system installed, land owners usually are advised to conceptualize and map out a landscape design plan. This map or blueprint will determine the amount of water each lawn section will need.

real-time-automatic-irrigation-system-project-report1The report explained the Real Time Automatic Irrigation System through block diagram. Under interface the sensor, relay and Zigbee interface is defied very clearly and pictorial way. Irrigation is the artificial application of water to the soil usually for assisting in growing crops. In crop production it is mainly used in dry areas and in periods of rainfall shortfalls, but also to protect plants against frost.
