Sheet Metal Drawing Btech CIVIL Project Idea

The Sheet Metal Drawing Btech CIVIL Project Idea deep drawn technology is one of the most challenging processes in manufacturing. The sizes, shapes, thickness and deep drawn metal used to produces sheet metal deep drawn parts cover a diverse range of variables. Individual variables should be evaluated carefully to determine the optimum manufacturing method. The deep drawing of irregular square cup was investigated in this paper. To predict the damage of irregular square cup, different blank hold forces and blank shapes were studied in the numerical model.

sheet-metal-drawing-btech-civil-project-ideaThe experiment was carried out with the optimized blank force holder and blank shapes, the crack and thickness distribution were investigated. The results of the experiment accorded with those of the numerical simulations, which show the validity of the simulation to predict where the damaged zones will appear in the part during the deformation. Many objects, such as cardboard and metal boxes, cake pans, mail boxes, HVAC ducts, roof gutters, are made from flat sheet material that, when folded, formed, or rolled, will take the shape of an object. Since a definite shape and size are desired, a regular ortho-graphic drawing of the object is made first: then a development drawing is made to show the complete surface or surfaces laid out in a flat plane.

Conclusion:

The sheet metal deep drawn technology is one of the most challenging processes in manufacturing. The sizes, shapes, thickness and deep drawn metal used to produces sheet metal deep drawn parts cover a diverse range of variables. Individual variables should be evaluated carefully to determine the optimum manufacturing method. Regardless of the many factors involved affecting the draw quality, the most important element to a successful sheet metal deep drawing operation is the smoothness of sheet metal flow. The following are key elements affecting metal flow during deep drawing process and each of them should be considered when designing or troubleshooting sheet metal deep drawing stamping tools.

Slip Forming Civil Seminar Topic

Slip Forming Civil Seminar Topic: Civil engineering course put more attention to concrete and reinforcement while almost ignoring the major component like form work. No attention is paid to economic design of form work. Form work costs approximately 10% of the total cost of the construction projects but at the same time sheltering/scaffolding involves major capital investment.

slip-forming-civil-seminar-topicThe construction industry today lacks Engineers who can design a good form work system. There are enough Engineers to do concreting, reinforcement and a structural design but there are not many to improve upon the form work. The procedures so far have been mainly hit and trial at least for the smaller construction companies. In spite of being such a major capital cost component, no enough research has been done to minimize the cost of form work.

The increasing shortage of skilled carpenters, the cost of timber and economic disadvantages of economic disadvantages of traditional purpose built forms have made the use of SLIP FORMING is necessary. So that revolutionary technique called SLIP FORMING is in introduced. Slip forming is technique of construction using mechanized form work. Slip forming is process of continuous lifting of form work by a hydraulic system of jacks and pumps.

Conclusion:

With the invention of slip forming technique and due to speedier completion of work by the technique, there are substantial savings in cost in terms of wages and interest. This technique has no comprises against quality control and Homogeneity of structure. The cost saving will not appear automatically just because slip forming has been used .This technique has a lot of scope for improvement. But it can be adapted for tall framed structure. For slip forming work ordinary concrete of equally M20 &M25, rarely M30. Generally Portland cement is used for concreting. Fast setting cement in special cases work during winter and slip form progress is chosen. After dismantling the slip form components it can be used for span more than 25 years.

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.
