Our 1000+ Basic Civil Engineering questions and answers focuses on all areas of Basic Civil Engineering subject covering 100+ topics in Basic Civil Engineering. The washout valves are primarily used for normal maintenance works such as that of water main. In order to make a elastomeric bearing act/ function as a soft spring it should be made to allow it to bulge laterally and also the stiffness compression can be increased by simply increasing the limiting amount of the lateral bulging. But in the case of concrete barriers their purpose is not to absorb energy of vehicles crashing into the barrier but to retain them. Applied Mechanics. In case this valve is not installed then the pipe section of the branched out pipe would remain dry during normal operation and high chances of damage and leakage can take place. On a per pound basis, steel pipe is stronger in bending and is less likely to buckle in axial compression. In case of pipes which contain spigot and socket joints, it enables pipes to get supported along pipe lengths in place of sockets. Due to the above reasons pot bearings are preferred over elastomeric bearings in such cases. But the difference also in this method is that the amount of reinforcement used is much more than the first approach. Question 10. 15 signs your job interview is going horribly, Time to Expand NBFCs: Rise in Demand for Talent. A classic case is of lead solder (containing lead & tin), in which the melting point of the constituent elements are lowered, not necessarily a desirable property. The components of a typical waterproofing system on the roof of a pumping station are as follows: Question 21. Generally the upper bearing plate comprises of the following components: The bearing initially is placed right in the middle point of the upper bearing plate. The gate valve installed above usually remains open during normal operation. Cavitation works on the principle of Bernoulli's Equation. The major types of reinforcements used in prestressing are: Question 6. Beddings are primarily made up of granular or concrete materials. During the installation of bridge bearings the size of the upper plates is reduced to save the material costs. Building Materials. Waste Water Engineering. Question 17. Young's modulus (E) describes tensile elasticity, or the tendency of an object to deform along an axis when opposing forces are applied along that axis; it is defined as the ratio of tensile stress to tensile strain. Question 39. This helps in vastly reducing the chances of other vehicle hazards. Here’s list of Questions & Answers on Basic Civil Engineering Subject covering 100+ topics: The section contains questions and answers on classification and properties of stones and timber, sand and aluminium properties, lime classification, cement properties, ingredients and manufacturing of cement, cement types and grades, bricks types, qualities and manufacturing of bricks, types and manufacturing of tiles, timber seasoning and defects, paint types, varnish, fine and coarse aggregates, sieve analysis, glass, rubber, pvc, adhesives and cost effective materials. They are used to provide a more uniform support for the under pipes so that the bending moment longitudinally can be reduced greatly. Once the process of concreting is performed the striking of the formworks should be done as soon as possible as delay in this process can lead to the discoloration of the concrete structures. There are several solution to the rectification of the problem of mud waves: Question 22. Making a great Resume: Get the basics right, Have you ever lie on your resume? Question5: What … Explain The Mechanism Of Cavitations In Pipes And Drains? Sub-bases implementation requires a lot of workmanship which can lead to an un-uniform distribution of the sub-base. What Is The Tallest Man Made Structure In The World? This leads to the damage of the pipelines as a high level of dynamic pressure is created. Question4: Why are steel plates inserted inside bearings in elastomeric bearings? These air bubbles suddenly collapse on entering a region of high pressure. Describe Briefly The Advantages And Disadvantages Of Using Plastic And Timber Fenders? It is different from absorption, in which a substance diffuses into a liquid or solid to form a solution. Joints which are formed from the cope level to the toe level of seawalls through a complete vertical plane are known as slip joints. In Reclamation Works What Are The Importance Of Geotextiles And Sand? When the depth of a box girder bridge exceed 1/6th or 1/5th of the bridge width then the design recommended is that of a single cell box girder bridge. The surface provide for the membrane should always possess good cohesion properties and must be thin so as to prevent any un-uniformity. Which Is Stronger Solid Steel Rod Or Hollow Steel Pipe? Do you have employment gaps in your resume? But economically this method can be expensive as compared to others. The section contains questions and answers on surveying terms, chain, compass and plane table surveying, levelling equipments and methods, contouring and edm. To detect the elastic and deformations (plastic) of any of the test nails employed. One should spend 1 hour daily for 2-3 months to learn and assimilate Basic Civil Engineering comprehensively. In one case, it refers to when atoms, molecules, or ions enter some bulk phase - gas, liquid or solid material. The purpose of separation membrane between the concrete pavement slab and the sub-base are as follows: A good example of a separation membranes is polythene sheeting which is commonly used. What Do You Understand By “preset” During The Installation Process Of Bridge Bearings? Question 28.
