Drawings required for road projects

 There are many kinds of drawing are prepared for establishing a road project.



  1. KEY MAP - It shows the proposed & existing roads & important places to be connected.
  2. INDEX MAP - It shows the general topography of the area/site by using symbols.
  3. PRELIMINARY SURVEY PLANS - It shows details of various alternate alignments.
  4. DETAILED PLAN - It shows the ground plan with alignment & the boundaries including existing structures.
  5. LONGITUDINAL SECTIONS - It shows the details of longitudinal section such as datum line, existing ground surface and vertical profile of the proposed road and position of drainage crossings.
  6. DETAILED CROSS- SECTION - They are drawn at every 100m interval or where there are abrupt changes in level. It shows the area of cutting and filling.
  7. LAND AQUISITION PLANS & SCHEDULES - It shows all general details such as building, wells, nature of gradients and other details required for assessing the values.
  8. DETAILED DESIGN FOR CROSS-DRAINAGE AND MASONRY STRUCTURES - It shows the details of any complicated portion of the structure like cross-drainage work.
  9. LAND PLANS FOR QUARRIES - A separate land plans is prepared, if any quarry exists for construction materials.

Thank you.

What is PVC ? What are the advantages of it as a construction material ?

Image
  PVC - Polyvinyl chloride It is a vinyl polymer which structure is very much similar to polythene. It is produced by the free radial polymerization of vinyl chloride. In the recent years, the use of polyvinyl chloride has been increase in construction work due to their excellent property. It is resistance to fire, water, flame, and corrosion. It has light weight and great insulating property. As a building material, PVC is cheap and easy to assemble. It has become an alternative of conventional building materials like wood, concrete or clay. Advantages of PVC - Being a resistance to water, it is used to make shower curtains, water pipes etc. Being a hard plastics, it is used in window profiles, pipe, plumbing etc. It is extensively used in sewer industries for pipelines of the water. It is flexible. After addition of plasticizers, we can use it as roofing membranes and in electric cable insulation.  Thank you. Gracious! My Quora space My YouTube channel

Lug angle and tension splice - Introduction

Image
  Lug angle - Lug angle is an angle section of short length which connects the outstanding legs of angle section or member to the gusset plate.  It reduces the length of connection to the gusset plate and also reduces the shear lag effect.   When the lug angle is used, the unconnected length of main angle acts like a connected leg and hence entire cross-section area start resisting the tension. Thus, shear lag effect reduces and efficiency of the tension member increases.   Lug angle provides extra gauge line to accommodate the numbers of bolts.   Tension splice - Tension splice are the cover plates used on both sides of butt jointed members. A tension member is spliced when the length of section available is less than that of tension member required. when the members of different thickness are spliced, packing is required to fill the gap. The area of splices should be slightly more than that the member joined. It is also used when the size of the member changes at different lengths. T

Difference between butt joint and lap joint

Image
  LAP JOINT - In this joint, two members are overlapped and connected together. The load in lap joint has eccentricity because centre of gravity of load in both members are not in same line. Thus, a couple is formed which causes undesirable bending in the connection and the rivets may fail in tension. Also due to the eccentricity, the stresses are distributed unevenly across the contact area between the rivets and members to be connected.   BUTT JOINT - In butt joint, both members are placed end to end and additional plate/plates (cover plate) is provided on either one side or both sides and connected to the main plates. When one cover is provided, it is called single cover riveted butt joint and when double cover is provided,it is called double cover riveted butt joint.   It was the difference between lap and butt joint. Now, we will know superiority of butt joint. Butt joint is superior than lap joint because 1. In the case of a double cover butt joint, eccentricity of force does not
