How Dams Are Designed

The design of a concrete dam depends largely on the purpose of the dam, as well as the configuration of the site on which it will be built. There are two primary types of dams, overflow dams and non-overflow.

Overflow dams block the flow of a stream and harness the water for power generation, they are also often used to improve navigation and provide irrigation water. An overflow dam is designed so that water can be released, allowing the level of water in the reservoir to be regulated by a series of sluice gates, spillways and outlet tunnels.

Non-overflow dams are mainly used to tore water for drinking water supply, irrigation, or power; they also have a spillway, but its use is restricted for emergencies to lower the water level quickly during floods. The methods for releasing stored water in non-overflow dams are limited when compared to overflow as this design does not contain any outlet structures. However, water may be sometimes be pumped out for irrigation or other uses.

Why The Excavator Is A Major Piece Of Construction Machinery

Most construction businesses owe their success to just one machine, that is the Excavator. It is considered to be one of the most important pieces of construction machinery and offers a host of advantages to any business who makes use of it. From moving piles of debris, to leveling the land, the amount of man hours a heavy machine like this saves is at the extreme highs.

Large construction companies often make use of several excavators operating at different locations. But for smaller contractors, one is often enough for the size of the jobs they are likely to tackle. It’s also recommended that smaller businesses lease the machine, as spending the required money to own one is not cost effective until the business has grown substantially.

Excavators are used in other areas than construction. Often they are made use of for mining, rock cutting, agricultural and industrial related purposes.

Building a Product Prototype

A product prototype is basically the first stage of a product’s production. It is the product, only without any input from marketing departments, or without any effort having been put in to enhance the aesthetics or usability of the product.

Even though this is the case for most prototypes (or the first prototype anyway), you can still get a solid idea of what the product will be, because, arguably, the most important part of a product’s design has been accomplished; you’ve gone through the process of solving a problem with your product; that’s finished and you’ve got the theory down, and you’ve now proven it is possible to build.

After you’ve reached this point in the product design, you still have a lot of important decisions to make about the product. You need to take the pure, basic product and make it really user friendly and improve its appearance, before you’ll be able to declare it a success.
