Benefits of technology

The patent describes a ground excavation preparation apparatus that can be transported to a site and lowered to create a space above the ground surface. The apparatus has heat generation means to supply thawing energy, heat distribution means to transfer the heat into the ambient air, and hydraulic means to raise and lower the housing. The preferred embodiment is a rectangular, open-bottomed box with wheels that can be attached to a towing vehicle. The apparatus can be used to prepare ground for excavation by thawing it using the heat transfer piping and of the hydraulic means. The technical effects are improved efficiency and speed in preparing ground for excavation, reducing risks and costs.

Problems solved by technology

However, such excavation may be impractical, extremely difficult or impossible under certain circumstances.
One example of such circumstances is extremely cold weather which results in freezing of the ground surface and underlying material.
Prior art methods have used propane tanks as a source of fuel to thaw the frozen ground, but such tanks require frequent refilling.

Embodiment Construction

[0017]As depicted in the figures, the apparatus of the present invention comprises a trailer having a housing; mobility means; heat generation means; heat distribution means; and hydraulic means.

[0018]According to one embodiment, the housing may comprise an inverted rectangular open-bottomed metal box 2 approximately 8 feet wide, 20 feet long, and 2 feet deep. Other box dimensions are also within the scope of the invention.

[0019]The mobility means may comprise, at a first end of the housing, a frame 4 and hitch 6 assembly, as is know in the prior art, for reversible connection of the system to a towing vehicle for transportation of the system to and from an excavation site. At a second opposing end of the housing, the mobility means may further comprise a wheel assembly 8, preferably having at least one pair of wheels joined by an axle, the assembly pivotally connected to the second end of the housing, whereby lowering of the wheel assembly effects raising of the second end of the h...

Abstract

A ground excavation preparation apparatus for thawing a frozen ground surface prior to excavation, consisting of a trailer; a housing connected to the trailer; mobility means attached to the trailer for moving the apparatus; heat generation means above the housing for supplying thawing energy; heat distribution means within the housing for transferring heat into the ambient air within the housing; and hydraulic means connecting the trailer to the housing for raising and lowering the housing at an excavation site.

Description

TECHNICAL FIELD OF THE INVENTION[0001]The present invention relates to heavy equipment. In particular, the present invention relates to an apparatus for preparing terrain for excavation.BACKGROUND OF THE INVENTION[0002]It is common in carrying out infrastructure and industrial projects for there to be a need to dig into the ground at an excavation site. Various prior art technologies exist for such excavation. However, such excavation may be impractical, extremely difficult or impossible under certain circumstances.[0003]One example of such circumstances is extremely cold weather which results in freezing of the ground surface and underlying material. For ex ample, a utility line may need to be repaired under a frozen paved street.[0004]It is desirable to prepare the excavation site for excavation by thorough ground thawing. Prior art methods have used propane tanks as a source of fuel to thaw the frozen ground, but such tanks require frequent refilling. The present invention provid...
