Principles Of Chain Surveying Surveying definition is - a branch of applied mathematics that is concerned with determining the area of any portion of the earth's surface, the lengths and directions of the bounding lines, and the contour of the surface and with accurately delineating the whole on paper All land surveyor resume samples have been written by expert recruiters . 14. The angle between the lines is measured, and the chain measures the length. 1.2. Underground details include survey of water mains, sewer etc.

controlling stations) and main survey lines (i.e. 4. Read more

First the line AB, is drawn to scale on paper to form a base line. (iii) About one dozen ranging rods (the actual number depends upon the extent of survey). Take extra care in fixing new control points. (ii) Ground is fairly level. In this survey only measurements are taken in the field, and the rest work, such as plotting calculation etc. A triangle is a simple figure which can be plotted from the lengths of three sides even if the angles are not known. The area required to conduct survey is relatively small 2. The principles to be considered are: 1. Types of Survey As the definition of surveying implies, the practice of surveying is a very extensive activity. 3: Chaining Across Obstacles 18 5. 1. The survey prevents projects from falling off the work in another land. A chain survey team usually needs three people. In chain surveying only linear measurements are made i.e. The chain is held horizontally with zero ends of it at P on the ground, while the point Q1 vertically below the other end of the Chain at Q is found by means of a drop-arrow. The main principle of surveying is to divide the area of a survey into numbers of small survey areas by using triangles. The ends of the chain are provided with brass handles for easy handling. Chain surveying is a very common method of surveying that is used for less-precise but quick results. Chain survey is suitable in the following cases: (i) Area to be surveyed is comparatively small. $855.58. Followings are the principles of surveying which should be kept in mind while determining the relative positions of points on the surface of earth: To work from whole to part. Item Weight : 1.16 pounds. It is known as the compass traversing. Only 1 left in stock - order soon. Tie stations are points which are specified on the chain line (main survey lines) where it is required to identify interior details like buildings and fences.

Surveying: Principles and Applications Barry Kavanagh. The tools used to do chain surveying are easy to use.

The ground is level to some extent 3. Main stations. This is a very easy method of surveying. Also read : Total station - Principles and fundamentals What is chain surveying? 4.3 . Principle Of Chain Surveying. by Anre A. Working from whole to part is done in surveying in order to ensure that errors and mistakes of one portion do not affect the remaining portion.

Hence the principle of chain surveying is TRIANGULATION. According to the first principle, the whole area is first enclosed by main stations (i.e.

This is most suitable adapted to small plane areas with very few details. ISBN-13 : 978-1517666460. These are the below chain surveying instrument used for surveying are listed below: 1. Plotting of features on a map. What is Chain Surveying? PRICIPLES OF SURVEYING There are two fundamental principles upon which various survey methods are based, these are: i. Chain surveys can be easily done by a few men to survey. Chain surveying is not suitable for large areas having many details. Chain Surveying - Principles of Chain Surveying. 2. CHAIN SURVEY Introduction 7 Exercise No. Optical Square. (ii) A metallic tape 20 m or 30 m in length. These data in the filed book is used to draw the survey work on the paper by taking proper scale. The principles followed in chain surveying are: a. It is the simplest and accurate method of land surveying, In this, linear distances are measured on the filed.

The ground is level to some extent 3. Chain survey belongs to the easiest method of surveying.

These data in the filed book is used to draw the survey work on the paper by taking proper scale. Chain (Tape) surveying is the simplest form of detail surveying. 2: Closed Traverse 16 Exercise No. Answer (1 of 2): the general principles of surveying are- 1.To work from whole to part and 2.To locate a new station by at least two measurement from the fix reference. The surveyor swings the tape on chain line and selects the point on the chain where offset distance is the least (Fig. no angular measurements are made. Dimensions : 6 x 0.89 x 9 inches. If carefully done, it gives quite accurate results. In this method, the lengths of lines marked on the field are measured, while the details are measured by offsets and ties from these lines. This is suitable for the survey of small areas with simple details and a fairly flat area.

The main principle of chain surveying or chain triangulation is to provide a framework consist of number of well-conditioned triangles or nearly equilateral triangles. Under this type of survey, only measurements are captured in the construction site, and the other works, like plotting measurement etc. Principles Of Chain Surveying. In chain surveying, the area to be surveyed is divided into several smaller triangles, and it is well divided into these triangles. At the center of the chain, there is a circular talley used for easy reading. The chain surveying is the most commonly used surveying for quick and short measurements. In order to express your land area in acres, you will have to calculate the land area in square feet and then perform the necessary Draw on a map, walk a field while recording your path or enter coordinates - that is all there is to it In that case, the following 3 step calculation is used to determine damages Establishing a precise horizontal and Lough Neagh . Metric chains are generally available in the lengths of 5 m, 10 m, 20 m and 30 m. In this types of chain in surveying, tallies are fixed at each meter length of 5 and 10 meter chain and each 5 meter length for chains of 20 meter and 30 meter length, so as to enable fraction readings a chain with less trouble. Chain - Following types of chains are used Metric chain: It is available in lengths of 5, 10, 20 and 30 meters. The area is open and 4. Take the case of an area on ground with three straight boundaries AB, BC and CA. Chain survey is the simplest method of surveying. It gets its name from the fact that the chain is the most widely used piece of . In chain survey, the area to be surveyed is divided into a framework consisting of triangles.

Chain surveying is the branch of surveying in which only linear measurements are made in the field. PRINCIPAL OF CHAIN SURVEYING The principal of chain surveying is to divide the area into a number of triangles of suitable sides. Tape, 3. Principle of Chain Surveying. The final product of the survey is a map in hardcopy and/or digital form to the client. Care must be taken in the construction of triangles so that the chain survey process can be smooth. Astronomical survey: generally involve imaging or "mapping" of regions of the sky using telescopes. In surveying the chain, the triangle sides are measured on the field directly above the location by the survey chain. To get accurate results in surveying one should follow the following fundamental principles: (i) Work from whole to part. Chain surveying is a type of surveying that only takes linear measurements in the field. d. Independent Check. The early use of the name plain table reflected its simplicity and plainness rather than its flatness.

Principles Of Chain Surveying The basic principles in chain surveying are illustrated below: 1. Working from Whole to Part. Principles of Chain Survey. Basic Principles of Surveying. As a result, the survey area is divided into several small triangles. Chain survey is the simplest method of surveying. Indeed, even in a 10-meter chain, a meter of metal is appended Principles of Chain Surveying toward the finish of each meter. a) Chain Surveying. The tools used in chain surveying can be easily changed as needed. The surveying basic principles can be stated under two . This means that the area to survey is spilled into several small triangles. Metric Chain. The triangles developed must be WELL CONDITIONED TRIANGLES. PLANE TABLE Introduction 32 Irrespective of angular measurements, only linear measurements are undertaken.

The area to be surveyed is divided into a number of small triangles. The principle of surveys is traversed. This is a very easy method of surveying. What is Chain Surveying? Angles of triangles must not be less than 30 degree and greater than 120 degree. Principle of Compass Surveying. A simple definition of the chain is 'It is used to measure the distance between two points.' chain is used to measure the horizontal distance. PRINCIPAL OF CHAIN SURVEYING The principal of chain surveying is to divide the area into a number of triangles of suitable sides. Principles of Surveying. Indeed, even in a 10-meter chain, a meter of metal is appended Principles of Chain Surveying toward the finish of each meter. This is most suitable adapted to small plane areas with very few details. Measure the length with tap and angle with a compass. As a triangles is the only simple plane of geometrical figure which can be plotted from the lengths of the three sides even if the angels are not known. It is the type of surveying in which only linear measurements are made, no angular measurements are taken.

1: Instruments and Techniques 14 Exercise No.

It is used for measuring small areas of land when the level of accuracy required is not high. The principle of chain surveying is to divide the entire area into several triangles of suitable sides. Chain in Surveying. Define Surveying. The main principle of a chain survey is surveying by triangulation. Chain surveying is the basic and oldest type of surveying. Under this type of survey, only measurements are captured in the construction site, and the other works, like plotting measurement etc. Instruments Used in Chain Survey . The survey points are connected as a series of lines.

. Main stations are the end of lines that determine the boundary of the surveying. COMPASS SURVEY Introduction 21 Exercise No. The principle of chain surveying is the triangulation.

The ground is level to some extent. It is used in horizontal measurement on the earth's surface. An assistant holds the end of the tape on the object. Surveying is an art of determining the relative positions of various points on, above or below the surface of the earth by means of direct or indirect measurement of distance, direction and elevation. In surveying large areas, a system of control points are identified and they are located with high precision. 4: Distance between Two Inaccessible Points 26 Exercise No. Relevance of Chain Survey - Chain survey can be undertaken for the following purposes: 1. Chaining. 1. To fix the positions of new stations by at least two methods. Arrows, 4. Principles of Compass Surveying. Chain surveying requires chain, tape and ranging rods. Paperback. surveying class are: principles of surveying; linear measurements, chain surveying, leveling and its application in contouring, profiles and cross-sections. Thus, surveys are generally broken down into their purpose. It is measured by the magnetic bearing of the compass instrument. 3.6 out of 5 stars 2.
