The Maine Department of Transportation outlines specifications regarding the proper dimensions for temporary concrete barriers, including general notes, plan view details, elevation details, and more.

Maine Temporary Concrete Barrier General Notes

The Maine Department of Transportation’s general instructions are as follows:

1. Alternate barrier designs may be submitted for approval by the Resident.
2. Form a ¾” chamfer or radius on all exposed edges.
3. Galvanize connectors after forming. Connectors may be completely galvanized.
4. Galvanize the connector pin assembly after fabrication. Burr the threads on the pin after installing the nut.
5. The reinforcement shown is primarily for the impact performance of the barrier. Additional reinforcement may be advisable for handling the barrier and for ensuring its integrity over its service life.
6. When serving the additional function of channelizing traffic, the barrier should be supplemented by standard delineators, channelizing devices or pavement markings.
7. Barrier delineators should be bi-directional with a minimum effective reflective area of 8.0” squared as approved by the Resident. The reflector should preferably be of Methyl Methacrylate, and the housing of Acrylonitrile Butadiene Styrene. As an alternative, reflectors may be mounted on the top of the barrier.

A dry dock, also called a graving dock, is a basin that is fairly narrow. It is typically flooded with water to allow for a floating load to be pushed in. Then it’s drained to enable the load to be situated on a dry platform where work can be done. Dry docks are common for the maintenance, construction, and rehabilitation of various types of ships, boats, barges, and vessels. Sheet piles can be used in the construction of dry docks in a few different ways.

INSTALLATION

Oftentimes, when dry docks are being built, a cofferdam is constructed around them to allow for the area to be dewatered. Steel sheet piles are frequently used in cofferdam construction, as their interlocks do an excellent job of keeping water out. Additionally, they’re usually fairly quick and easy to install. They’re also quick and easy to remove when a temporary cofferdam is no longer needed.

SHEET PILE

Sheet piles are also used in the construction of dry docks themselves. Dry docks often are constructed similarly to quay walls and jetties, which can make use of sheet piles to create impermeable wall structures as well. When sheet piles are used to build dry docks, they are combined with concrete superstructures, and they are an affordable, convenient, hassle-free option. Dry docks may also be made of in-situ concrete cantilever walls or caissons. In-situ concrete cantilever walls may be the best choice for dry docks that require the most resistance to lateral loads.When sheet piles are used to create dry dock walls, the walls must be built to a considerable height and make use of concrete superstructures to allow for sufficient resistance to considerable lateral loads. A dry dock’s floor must be able to sustain pressure from hydrostatic uplift that occurs when the dock is dewatered after being flooded. A sheet pile dry dock’s concrete superstructure allows it to be resistant to bending and breaking. Additionally, it offers enough weight and strength to act against hydrostatic uplift in most cases.

CONCRETE CANTILEVER WALLS

Sometimes dry docks are constructed using in-situ concrete cantilever walls and then surrounded by an additional cutoff wall made of sheet piles to provide additional resistance. This often happens in the case of fully relieved dry docks. Fully relieved dry docks make use of a drainage system that removes water around them when it seeps into the soil. This drainage system ultimately can relieve some of the pressure put on the dry dock during dewatering. If additional drainage capabilities are needed in the case of fully relieved dry docks, a pipe system may also be installed. Partially relieved dry docks, which use drainage systems to only relieve hydrostatic pressure underneath their floors, also frequently make use of sheet pile cutoff walls to lessen seepage.

OVERALL

Overall, sheet piles can play an important role in dry dock construction. This is the case if they are used to build cofferdams to protect the dry dock as it’s being erected, if they are used as a part of the dry dock structure itself, or if they’re used to build a cutoff wall around a dry dock.

Steel sheet piles are used to make a continuous wall by creating extended structural sections that make use of an interlocking system that’s vertical. Walls of sheet piles are commonly used to retain soil or water. Steel sheet piles may be substituted for other types of sheet piles for certain applications. Other types of sheet piles include timber, concrete, and vinyl. There are pros and cons to each type, and some are better suited to certain projects than others. For the purpose of this article, we will be focusing on comparing new and used steel sheet piles. Steel sheet piles are a popular choice because they can support relatively heavy loads if needed and are incredibly watertight. They can also easily be driven into rocky ground as well as most other types of ground.

FUNCTIONS

Steel sheet pile can be purchased both new and used, and its age has little to do with its performance capabilities. When buying used, condition obviously matters, but the fact that sheet pile is used doesn’t necessarily make it inferior to new sheet pile if it’s in good shape. This is particularly the case if you can get a better deal on used sheet pile as opposed to buying new. Both used and new steel sheet pile can be used for projects involving:

• Culvert construction
• Cutoff wall construction
• Trench shoring
• Protection for foundation projects
• Boring pits
• Jetties
• Floodwalls
• Bulkhead construction
• Groin construction
• Seawall construction

And these are just some of the applications for new, used, and surplus steel sheet pile. Ultimately, the type of steel sheet pile (new or used) that’s best for your project will depend on things like the length you need, how much you need, the overall needs of the project, and your budget. It’s best to shop around to find the best deal that suits your purposes.

CONDITION

Generally, when you’re assessing the condition of used sheet pile, here are some factors to consider:

• Length, which can be measured with the use of a string line for straightness
• The overall, visible exterior condition, including the quality of interlocks
• The degree to which kinks, camber, or twist exists in interlocks
• Thickness (be sure to measure it in micrometers)
• The level of corrosion and whether or not it compromises structural integrity

QUALITY

While some might be tempted to buy dirt cheap steel sheet piles that are on their last leg if they’re just going to be used for one project, this isn’t advisable in most cases. Sure, they may be able to be installed and serve their purpose for a while, but you don’t want to have to repair them prematurely down the road. In the long run, buying higher quality steel sheet pile, whether it’s used or new is your best bet in most cases.

NEW VS. USED

All in all, there aren’t necessarily any downfalls to buying used sheet pile if it meets the needs of your project and can save you some money as opposed to buying new. But if you’re shopping around for steel sheet piles for your project, you may find yourself scratching your head when you stumble upon new or surplus sheet pile that’s actually cheaper than used. This phenomenon exists because there’s been rapid growth of new sheet pile production in recent years, and there have been some changes to the way sheet pile is made. In general, it now costs less to make sheet pile than it did a few decades ago. This drives down the prices of new sheet pile and creates a competitive market for sellers of both used and new sheet pile. It isn’t always the case that you’ll be able to buy new steel sheet pile for less than used, but it happens occasionally.Ultimately, however, whether you buy used or new, you probably won’t be going wrong, as long as you’re getting high quality steel sheet piles that work for your particular application.
