How Do Concrete Pumps Work?
Anyone working in the construction industry, dealing with all kids of constructions and concrete structures, knows that concrete pumps are indispensable for certain jobs. Concrete is a sturdy, durable and affordable construction material, therefore it is extensively used. A structure may employ either concrete blocks or poured concrete. Concrete pumps deal with poured concrete.
While it may not sound as complicated, sometimes liquid concrete must be poured in areas that are difficult or nearly impossible to access with cement mixers, for example the top of a building, or the middle of a long tunnel. Concrete pumps are designed to reach these difficult areas, feeding liquid cement from a great distance.
There are two main types of concrete pumps: the boom pump and the line pump. Boom pumps are ground based machines of large dimensions, with a crane or boom arm of varying lengths. This crane holds the length of rubberized or plastic tubing, feeding the liquid cement to its destination. This type of concrete pump is especially useful for high constructions with multiple stories, that require poured concrete high above the ground level. The boom pump is generally truck-mounted, with a large open reservoir in which mixed concrete is constantly added. The engine, either gasoline or diesel-powered, protrudes a driveshaft into the cylindrical chamber right at the base of the reservoir. The weight of the cement pushes it into this chamber. The cement is forced through the airtight chamber and up the boom, allowing liquid cement to be poured from a distance.
The line pump is portable, and is recommended for smaller jobs. In a nutshell, line pumps consist of a diesel power engine mounted on the back of a truck or a trailer. A large worm gear at the center of a funnel is controlled by the engine, and at the end of this worm gear a long rubber or plastic tube is attached. With a cement mixer, the cement is poured into the funnel and the turning worm gear pushes it down the tube. Generally, line pumps are used to fill wood or metal forms for certain structures, such as concrete slabs.
Depending on the needs and requirements of the construction project, a boom pump or a line pump will be necessary. You can find them for sale either new or used, or you can even find concrete pumps for hire. The prices vary depending on the model, capacity and type of concrete pump, but generally it will require a considerable investment. However, many constructions would not have been possible without concrete pumps, so it is a necessary investment.
In Wall Speaker Systems
In-wall speaker systems are an effective method to enjoy outstanding music while keeping the speakers hidden. Also known as in-ceiling speaker and recessed ceiling speaker, an in-wall speaker system is most ideal in a home theater environment. Open back, semi-sealed, and sealed systems are among the different types of in-wall speaker systems.
In-wall speaker systems have many advantages over a conventional speaker system. The main advantages of in-wall speaker systems are that they don’t occupy any floor space and are easy to hide. Further, it can be installed across any flat surface including ceilings and floors. Cost effectiveness, custom installation, compatibility, flexibility, increased power handling and easy installation are the other advantages. In-wall speaker systems are most suitable for multi-room audio systems. Usually, two styles of in-wall speaker systems are available in the market, one intended for home theater and the other for whole-house audio.
An in-wall speaker system functions in the same way as a regular one. But, the only difference is that, instead of installing within a cabinet, it is generally mounted in the ceiling. In-wall speaker systems use wall cavity as enclosure, and come attached with a grill and frame that can be painted according to the color of the ceiling or floor. A guide or manual demonstrating the step by step installation are available at the time of purchase of in-wall speaker systems, which makes the installation process quite easy.
In-wall speaker wires or cables and subwoofers are important for the proper functioning of in-wall speaker systems. In-wall speaker wires are available in both 14 and 16 gauges, and specially certified wires known as UL Class 3 rated cables are used for the better performance of in-wall speakers.
However, in-wall speaker systems have certain disadvantages. Since an in-wall speaker system is fixed in a particular area of the room, it is difficult to make further modifications. Diffraction loss also affects the performance of in-wall speakers. Another disadvantage is that the labor costs of in-wall speaker wiring are high.
