A _____________load is one that varies in its intensity and is usually temporal in nature, such as weight of a dump truck that might drive over a grave.

Dynamic Load

Types of Grave Liners

Grave box and Sectional Concrete box

AN _____load is encountered by the outer burial container when a sudden powerful application of force is introduced to the gravesite.

Impact Loads

what type of loads present great challenges to the uppermost surface of outer burial containers buried with a minimum covering of earth

Impact loads

Is an outer burial container required by law?

No- State and local law does not required that you buy a container to surround the casket in the grave. Many cemeteries require that you have such a container so that the grave will not sink in. Either a grave line or burial vault will satisfy these requirements.

What Materials are used to line a burial vault ?

Polystyrene, plastic, ABS and Various wrought metals

Differential Load

Soil placed on top of a grave for excavation of a nearby existing grave.

The ___________Load is comprised of the weight of the soil above the outer burial container, as well as the force exerted by the earth against the outer burial container's sides and bottom

Static Loads

impact load

Sudden powerful force ( ie, earth dumped on OB when grave is closed; dropping a backhoe bucket,

Static Load

The weight of the soil above the outer burial container 18" of earth covering approx 4000 lbs

Methods of Closure ~ Concrete burial vault

Two piece 1. base 2. cap (cover) ~ TOP SEAL - utilizes an epoxy compound in conjunction with tongue-in-groove construction at top edge and the id of the vault

Method of closure - Metal burial vault

Two piece 1. base ( shallow) 2. Dome (top) Measured in Gauge 7,10,12 ga.

concrete sectional liner

a grave liner consisting of six or eight slabs of unfinished concrete placed around the casket.

an outer enclosure which offers protection from the earth load but without protection from the elements

Outer Burial Container

What outer enclosure which offers protection from the earth load as well as possessing sealing qualities

burial vault

A_____________ is an outer enclosure consisting of a body and a one or two piece lid, with holes frequently present in the base

grave box

What outer enclosure which offers protection from the earth load without protection from the elements

grave liner

Vault

outer enclosure which offers protection from the earth load as well as possessing sealing qualities. constructed of concrete, metal,plastic polymers and fiberglass

Grave liner

outer enclosure which offers protection from the earth load but without protection from the elements. DOES NOT Possess sealing qualities. constructed of concrete, wood, plastic polymers & fiberglass

The ____ ____ method of closure utilized as sealing compound in conjunction with tongue-in-groove construction at the TOP edge and the lid of the vault

top seal

Method of Closure Double Seal

utilized the principle of air seal in conjunction with an epoxy material at the junction of the dome & base of the vault.

Dynamic Load

varies in its intensity, temporal in nature (ie, back hoe parked on the grave)

Grave box

~~outer enclosure consisting of a body and a one or two piece lid ~~most commonly constructed from concrete ~~Unfinished wood grave boxes are sometimes referred to as a ROUGH BOX.
