Pipe Joining Techniques - Manually
Why are manhole covers normally round and not square or rectangular? So they don't fall in!
Manholes, which interconnect underground sewerage pipes, and serve as a point of entry for cleaning the pipes, are located at every major sewer pipe junction, and are capped with round manhole covers. The reason for the circular construction of these covers is, quite simply, that covers of any other shape would fall through the manholes by virtue of their varying diameters. Circular manhole covers do not vary in width, or in diameter, as is the case with these other shapes, thus remaining in place despite the street traffic running roughshod over them.
Manufacturers craft the manhole covers together with the smaller sized lip, upon which they rest, at the same time to ensure a tightly sealed fit. Additionally, the manufacture of circular manhole covers is easier and more accurate than the manufacture of covers of any other shape. Lastly, round manhole covers, once removed, require less lifting and less manpower, as their shape allows them to be rolled.
Why Hydraulics ? Lets review some information about the "Hydraulic Solution", Benefits of Hydraulic Equipment.
vs. Pneumatic (Air Powered) Tools
* No exhaust air creating noise, dust, and breathing problems.
* Less wear and longer life as all parts continuously move in oil. Will not freeze in cold weather.
* Much higher performance to weight ratio (i.e. a 72 lb. hydraulic breaker will outperform a 90 lb. pneumatic breaker).
* Far more portable than pneumatic (transportable by pick-up truck).
* Versatility to be powered off other hydraulic sources (such as a Skidsteer or Bobcat).
* Lower initial cost and less fuel consumption.
vs. Electric Powered Tools
* No danger of high voltage injuries and can be used underwater.
* Longer life and less maintenance.
* Tools like the Hand Held Core Drill have built-in pressure relief if the bit binds in the cut - resulting in greater operator safety.
vs. Gas Powered Tools
* No danger of hot and poisonous exhaust.
* Far less maintenance - as the power source is removed from the work area.
* Less noise and weight - no engine on the tool.
GENERAL COMPARISONS AND WHY HYDRAULICS.
* High power-to-weight ratio - the highest of all available power sources.
* Greater operator comfort + less fatigue = greater productivity.
* Lowest maintenance time and longer life of the components.
* Less noise - no engine on the tool. Perfect for sound-sensitive jobs.
* Hydraulic tools can be used underwater!
* Will operate in sub-zero conditions when other tools freeze up.
* One power source can run many different hydraulic tools.
* Extremely portable power unit - small and easy to maneuver.
* Versatility to run off other hydraulic power take offs (PTOs).
* Operate indoors - no exhaust fumes from the tool.
* Easy to cut wet - hydraulic tools are a closed system that cannot be contaminated by water, dust, or debris.
*** ADVANTAGES OF USING COMPACTION WHEELS ***
Why Use Compaction Wheels ?
Our open-rim design allows maximum penetration through the lift, with standard densities achieved in 6-10 passes under normal soil conditions, the wheel processes and levels the material as it compacts. Bridging and voids are eliminated as compaction takes place from the bottom of the lift up.
Compaction Wheels assist with Safety
* Eliminates the need to have people in the trench.
* No vibration to bring down trench walls or bow green concrete
* A real plus in light of tough OSHA regulations
Compaction Wheels assist with Production
* Process the material as you compact
* Increase your production 75% or more over conventional methods of compaction, such as vibratory rollers and boom - mounted vibratory plates Backfill and compact as fast as you can excavate
