One issue that must be taken into consideration when undertaking a construction project is the long term settlement and stiffness of the ground such as the soil, clay, or soft silt. The solution to ensuring much quicker soil consolidation and settlement has been the development of Wick Drains. Wick drains are used when there is a problem with soil consolidation.

Also known as Prefabricated Vertical Drains (PV Drains), wick drains are flat, plastic fabric coated channels surrounded by a thin geo-textile filter jacket that functions as a free-draining water channel. The fabric acts as a filter because it maintains permeability while preserving the fine soil particles.

Wick drains reduce the distance water travels to a drainage path thereby reducing the time of settlement. Basically, they act as a free-draining water channel. Wick drains are suitable for peat, silts, clay, silt sands, and sludge waste from industry. Both the core and geotextile filter jacket of wicker drains makes them extremely durable and resistant to chemicals and many micro-organisms such as bacteria.

Wick Drains are a cost efficient method of hastening the consolidation process of fine grained soils in order to cut down on the time for starting construction. It allows for the drastic reduction time for long term settlement to occur. The use of wick drains helps to remove excess water, consolidate the compressible soil, and promote soil settlement. This allows a construction project to start in a few months instead of 12 months or more.

Special equipment called ‘Stitchers’ are used to install wick drains. The ‘Stitchers’ are mounted on a crane containing an installation mandrel that holds the wick drain. The mandrel along with the wick drain is driven hydraulically or vibrated into the ground allowing the penetration of rocky soil. When the mandrel is withdrawn, the wick drain remains in the ground. Depending upon the soil conditions, the speed of installation can be up to 2,000 feet per hour. As the soil consolidates, it increases in strength because there is a large reduction in water.

Wick drain projects have included: sedimentation ponds, buildings, airport runways, highway embankments, dams, golf courses, large storage areas…etc. The installation of wick drains is essential in areas that contain high fills that have to be positioned over low strength soft soils. The rate of soil consolidation and settlement depends on how quickly the water leaves the soil through the wick drain process. This is largely determined by the size of the spacing between the wick drains as well as the permeability of the water.

The particular design curves of drains Canada spacing chosen, the fill height, and consolidation time, all allow construction to begin much sooner. The costs of installing a wick drains depends on a number of factors that include: soil conditions, difficulty of pre-drilling, type of drain used, size of the project…etc. There are professional companies that specialize in installing wick drains. Today, the installation of wick drains has become an invaluable component of a construction project that requires a faster rate of soil consolidation and settlement.

An Xbox 360 that seems to be getting no video signals is a big problem. Everything seems to be moving and humming like usual, you wouldn’t know anything was wrong if it weren’t for that minor detail of nothing being displayed on your television. All lights are green, and everything looks the exact same it did last night. Why is this happening?

Still receiving audio on your Xbox, but no video, is actually pretty common. Note: though there is typically still audio, that will sometimes go out too. It is annoying, irritating, pesky, and irksome; yes, but it’d be a lot more productive just to fix it.

To be sure, though, double check that the AV cable is properly plugged into both the Xbox and the TV. Also, make sure your TV is in fact on and working. For the sake of redundancy, try running the Xbox with a friend’s TV and AV cable. This does not usually fix the problem, but it is still important to check. What you can gather from this, is that though the AV cable seems to be sending information properly, nothing is sending information to it. And that is definitely not normal.

What causes this to happen? Unfortunately, it’s the same thing that causes the famous Red Ring of Death. At some time time in its career, probably more than once, your Xbox failed to get proper circulation and overheated. You may not have even noticed it when it happened, but the heat causes strange things to happen inside that shiny shell. Video signals cutting out is a common effect. Really, this no video error is like having the red ring of death–just minus the physical red lights.

If you feel less than comforted by this, I understand. Regardless, there is a positive to this odd predicament. Red ring of death is quite well understood, and since these two are basically the same problem; if you can fix one, you can fix the other.

When an Xbox 360 is repeatedly used, it heats and cools over and over again. Though not usually a problem, after some time certain components can become damaged by this ebb and flow of heat. One such part is the GPU. The graphics processing unit–doesn’t that sound like it would be responsible for a video related problem? As it turns out, it is. The GPU doesn’t shatter into pieces or anything like that, its link to the motherboard just weakens. Because of this wimpy connection, not all the right information gets sent out to the rest of the Xbox. And your lovely visuals are the first to go.

Repairing this means going in deep. You have to reestablish the link between the motherboard and the GPU. At the same time, it is a very good idea to replace the old thermal compound you will find there. Improving your Xbox’s cooling will prevent this problem from coming up again.

This all sounds very intimidating for such a seemingly simple no video problem on your Xbox. Luckily, as daunting as all this may sound, the fix is rather simple! It can be done by a beginner in roughly an hour. Why wouldn’t you want to try that?
