What to do before installing a RCP?
Just before installation, each RCP section is cleaned to remove all dirt from the pipe's bell. If the surface is not properly cleaned, it may prevent proper homing of the pipe. After cleaning, workers apply a lubricant to the pipe bell, using a brush or gloves.
How many workers are needed to install RCP?
Installing each section of RCP requires at least two workers to manage the pipe. The large pipe is lowered into the trench with a crane or backhoe, while the workers guide the pipe section into place. The smaller pipe may be set by hand. Typically, the spigot end of the new pipe is inserted into the bell of the pipe at the end of the installed pipeline, then the new section is pushed into place with a crowbar, pipe pullers, or other means.
How wide should a RCP trench be?
Trenches for RCP should be wide enough to accommodate at least two pipes. This provides sufficient room to verify the required slope, and it helps ensure that any subsequent trenching will not impact the pipe installation or compromise worker safety. The grade (pipe slope) is established during trenching, followed by laying down a bedding material. The bedding should be free of debris and must provide a uniformly level surface. When setting RCP into the trench prior to installation, the pipes should not be supported on their bells, as this can damage them.
What happens if a RCP gasket is not stretched?
If the gasket is not stretched, the pipe could leak at the joint or the bell can crack.
How high should backfill be placed on a pipe?
The backfill material is placed evenly in lifts on both sides of the pipe until the trench is filled about one foot above the top of the pipe. It is important that the material is not be bulldozed into the trench or dropped directly onto the pipe.
What is reinforced concrete pipe?
Reinforced concrete pipe, or RCP, is one of the standard materials used in storm sewer systems, sanitation systems, and large irrigation projects. Reinforced concrete offers high strength and durability at competitive costs and is the primary alternative to high-density polyethylene (HDPE) plastic pipe in many applications. One benefit of concrete is its inherent strength, which simplifies installation and backfilling procedures. On the other hand, RCP is very heavy and must be handled carefully during transportation and installation.
What is grade in pipe?
The grade (pipe slope) is established during trenching, followed by laying down a bedding material. The bedding should be free of debris and must provide a uniformly level surface. When setting RCP into the trench prior to installation, the pipes should not be supported on their bells, as this can damage them.

How is a large pipe placed in a trench?
The large pipe is placed in the trench at first. This can be performed by means of a crane or backhoe, while the workers assist in the proper placing of pipes in the trench. The spigot end of the pipe is inserted into the bell of the pipe already installed.
What are the two main parts of a reinforced concrete pipe?
Reinforced concrete pipes require proper and safe handling operation. The two main parts of RCP are the bell and spigot. The wide and flared ends of the pipes are called bell and the narrow end of the pipe used to join into the bell of the adjacent pipe is called a spigot. Both these parts require special care while handling.
How many workers are needed to install concrete pipes?
Generally, the installation of concrete pipes requires a minimum of two workers. The large pipe is placed in the trench at first. This can be performed by means of a crane or backhoe, while workers assist in the proper placing of pipes in the trench.
Where is the spigot end of a pipe inserted?
The spigot end of the pipe is inserted into the bell of the pipe already installed. Then the new section is installed on the pipe using a crowbar or pipe pullers.
Can lubricant be used on concrete pipe?
The lubricant used must not make the gasket roll away and damage the ends of the pipes. To ensure a good seal with the joint gasket, the spigot or tongue of the concrete pipe must be cleaned and lubricated.
How much cover does a RCP 3 bedding need?
In short, our standard stock RCP and a Type 3 bedding will handle nearly every possible scenario up to 13’ of cover that you will encounter in designing projects.
What size RCP is required for Cemcast?
Class 4 RCP is required in sizes 18” and 30” when only 1’ of cover is available with a Type 3 bedding. From 1’ to 13’ of cover, these are the only two exceptions in which a standard Cemcast stock class will not suffice.
What type of backfill is used for clay?
There are four types of backfill, ranging from Type 1 through Type 4. Type 4 allows clays and silts for backfill material with little or no compaction, which provides the least support. Type 1 consists of highly compacted granular material and provides the most support.
How many equations are needed for plastic pipe?
By comparison, when planning a plastic pipe installation, the engineer needs to work through 21 equations for each pipe diameter, bury depth, and soil type. The structural integrity of RCP simplifies every part of the process – from soil analysis and bedding through installation. When designing a pipe installation, you can’t control who becomes the low bidder, but you can control the pipe material.

These representatives are available to present information to groups on a wide variety of design and quality control topics.
What is a pipe association?
Pipe Association, or a local concrete pipe producer to arrange for a tour and information sessions.
What happens when a concrete pipe cracks?
As load on the pipe increases, and the tensile strength of the concrete is exceeded, cracks will form as the tensile load is transferred to the steel. Typically, the cracks form a V-shape with the largest part of the crack at the surface.
How high should I fill a concrete pipe?
In some cases where extremely heavy machinery will be traveling over the pipe, you may have to utilize a concrete pipe with strength above a Class V pipe, the highest class of pipe denoted in ASTM C 76.AASHTO M 170. This can be accomplished by working with your local producer. However, in most cases where an AASHTO HL-93 highway load is applied, and the fill height is equal to or greater than 1 foot of cover , a standard Class III pipe or greater will suffice. For standard HL-93 highway loads, the required D-load at fill height increments of 1 foot can be found in the ACPA Fill Height Tables. For other design load considerations, ACPA Design Data #1 “Highway Live Loads on Concrete Pipe”, or the ACPA “ Concrete Pipe Design Manual ” can be consulted for design assistance.
