Concrete Pumps and its types

CONCRETE PUMPS

 concrete pumps are tools used to convey liquid concrete from the source of concrete to the place of casting.

 PRINCIPLE OF CONCRETE PUMP

A basic concrete pump was initially developed as a two-cylinder hydraulic pump. This works by the principle of one piston drawing the concrete from the hopper (concrete source) and the other piston pushing it into the discharge outlet pipe. The decision of which cylinder has to be opened to the hopper and which must be opened to the discharge pipe is controlled by means of a valve. With future developments, variations in this design were bought to facilitate high-pressure pumping when concrete have to pump at different heights and lengths. This development got great demand in the fast construction of high-rise buildings.

TYPES OF CONCRETE PUMPS

Based on the pumping pressure, ease of working and developing technologies different concrete pumps have been developed. The main classification of concrete pumps are:

1.     Line Concrete Pumps

2.     Boom Concrete Pumps

1. Boom Concrete Pumps

Boom concrete pumps stay at one particular position for the entire time of concrete pouring on a construction project. Hence these are stationary concrete pumps. They have a larger dimension which is placed on the ground. These have crane or boom arm attached to it in different lengths.

   The concrete pumping to different heights like in the construction of high-rise building can be performed by boom concrete pumps. Boom concrete pumps allow the pipeline to reach along, upwards and below. Hence tight spots can be cast by these pumps. Obstacles during the concrete casting path can be easily overcome by such pumps.

2. Line Concrete Pumps

Line concrete pumps are compact units that are mainly used for small construction projects. The arrangement has a line pump attached to the back of the truck or the trailer. Hence the arrangement is also called as trailer mounted concrete pump or truck mounted concrete pump.

NOTCHES AND WEIRs

Image
   NOTCH ,WEIR AND ITS TYPES Notch A  notch  may be defined as an obstruction over which the flow of liquid occurs   In case of measuring tank or reservoir, the opening is provided at the side of the tank such that the liquid surface in the tank is below the top edge of the opening. Weir A  weir  is a notch on a large scale used for measuring the flow of a river, canal etc. It is a concrete or masonry structure of substantial breadth built across the river in the direction of flow. This allows the excess water to flow over its entire length to the downstream side. Thus a weir is similar to a small dam constructed across the river, with a difference that the excess water flows downstream only through a small portion called  spillway  and in case of weir, the excess water flows over its entire length. Nappe and crest The sheet of water flowing through a notch or over a weir is known as  nappe  or  vein . The bott...

 THE BASICS OF REBAR: A COMPREHENSIVE GUIDE FOR BEGINNERS The Basics of Rebar If you have ever wondered what gives strength and stability to the concrete structures that we see around us, the answer is (most commonly) rebar. Rebar, short for reinforcing bar, is the steel rods that are embedded in concrete that provide tensile strength to what is actually and prevent cracking. Rebar comes in different shapes and sizes, but the most common type is deformed steel rebar, which has ridges or indentations along its surface to create a better bond with the concrete. Deformed steel rebar has been used in the construction industry for over a century, and it has revolutionised the way we build. With rebar, and using elements such as beams,  beam ties , rebar mesh, and reinforced walls, we can create taller, stronger, and more durable structures that can withstand natural disasters, environmental changes, and human activities. Some of the most iconic buildings in the world, such as...

What are different diameters of steel used in construction field?

         In the construction industry, the appropriate selection of materials is crucial as they form            the fundamental basis for determining the strength and durability of structures. TMT (Thermo-Mechanically Treated) Steel is one of the essential components in construction as it stands out for its exceptional strength and ductility in building structures. Thus, contributing to the prolonged longevity and durability of the structures. In this article, we will delve into the different sizes of  TMT steel bars  and their different uses in the construction industry. These TMT Steel bars come in different sizes based on their varied diameters. The different diameter of steel bars are as follows: 8mm Steel Rod 10mm Steel Rod 12mm Steel Rod 16mm Steel Rod 20mm Steel Rod 25mm Steel Rod 32mm Steel Rod, etc TMT bars of varied sizes, play a pivotal role in diverse infrastructure initiatives, the versatility of TMT bars is ...
