Abstract
Abstract A muddy borrow soil base material blasting nozzle which has a muddy borrow soil base material injection port having one end of throttled shape, a cylinder integrally provided at the end of the muddy borrow soil base material injection port, and an air intake port formed near the end of the injection port at the side face of the cylinder, the air intake port being used as an intake port of one or more threadlike, ropelike or tapelike continuous elements into the cylinder, and a process for preparing a vegetation bedrock using the muddy borrow soil base material blasting nozzle having the steps of press-fitting a muddy borrow soil base material into the blasting nozzle, blowing the threadlike, ropelike or tapelike continuous elements introduced by intaking from the air intake port of the blasting nozzle into the cylinder together with the muddy borrow soil base material from the discharging port of the nozzle toward the surface to be executed to prepare a plant germinating and growing bedrock. Thus, the nozzle can obtain stably reinforced surface to be executed with large possible blasting amount per one blasting, large discharging distance, good water retention properties, temperature maintaining property, drainage and air permeability by a method of employing a mixture blasting unit of muddy material and fibers.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
118 words
A blasting nozzle for layering a vegetation bearing soil material onto barren ground comprising a nozzle terminating in an injection port, an agitating cylinder having a discharge port connected to said nozzle; means defining an air intake port adjacent said injection port, guide means disposed adjacent said air intake port for receiving a continuous strand element, and a valving means for valving said injection port whereby a slurry mixture of said vegetation bearing soil material is fed under pressure through said injection port to create a negative pressure thereat, and said negative pressure causing the continuous element to be intimately mixed in said agitation cylinder with the vegetation bearing soil material being forceably ejected through said injection port.
Claim 2
Dependent Claim
118 words
A blasting nozzle for layering a vegetation bearing soil material onto barren ground comprising a nozzle terminating in an injection port, an agitating cylinder having a discharge port connected to said nozzle; means defining an air intake port adjacent said injection port, guide means disposed adjacent said air intake port for receiving a continuous strand element, and a valving means for valving said injection port whereby a slurry mixture of said vegetation bearing soil material is fed under pressure through said injection port to create a negative pressure thereat, and said negative pressure causing the continuous element to be intimately mixed in said agitation cylinder with the vegetation bearing soil material being forceably ejected through said injection port.
Claim 3
Dependent Claim
37 words
A blasting nozzle as defined in claim 1 and including means for introducing a hydrophobic agent adjacent said injection port and into said agitating nozzle for mixing with said vegetation bearing soil material and said continuous element.
Claim 4
Dependent Claim
151 words
A blasting nozzle for layering a vegetation bearing soil material onto barren ground to promote plant life thereon comprising a blasting nozzle, said nozzle having an injection port, an agitating cylinder having a discharge port connected to said nozzle in alignment therewith, agitating blades connected to the interior walls of said cylinder, means for introducing a slurry mixture of said vegetation bearing soil under pressure to said nozzle whereby the flow of said soil through said injection prot creates a negative pressure thereat, means defining an air intake port adjacent said injection nozzle, a continuous element threaded through said air intake port whereby the negative pressure created by the flow of soil through said injection port causes said continiuous element to be fed into said soil, and said soil and element being intimately mixed in said agitating cylinder whereby the mixture exiting said discharge prot is layered onto a barren ground.
Claim 5
Dependent Claim
151 words
A blasting nozzle for layering a vegetation bearing soil material onto barren ground to promote plant life thereon comprising a blasting nozzle, said nozzle having an injection port, an agitating cylinder having a discharge port connected to said nozzle in alignment therewith, agitating blades connected to the interior walls of said cylinder, means for introducing a slurry mixture of said vegetation bearing soil under pressure to said nozzle whereby the flow of said soil through said injection prot creates a negative pressure thereat, means defining an air intake port adjacent said injection nozzle, a continuous element threaded through said air intake port whereby the negative pressure created by the flow of soil through said injection port causes said continiuous element to be fed into said soil, and said soil and element being intimately mixed in said agitating cylinder whereby the mixture exiting said discharge prot is layered onto a barren ground.
Claim 6
Dependent Claim
30 words
A blasting nozzle as defined in claim 3 and including means disposed adjacent said injection nozzle for introducing a hydrophobic agent into said soil material discharging through said ejection port.
Claim 7
Dependent Claim
17 words
A blasting nozzle as defined in claim 4 wherein said continuous element comprises a polyethylene flat yarn.
Claim 8
Dependent Claim
17 words
A blasting nozzle as defined in claim 4, wherein said element comprises a continuous multiple folded tape.
Claim 9
Dependent Claim
16 words
A blasting nozzle as defined in claim 4, wherein said element comprises an aluminum foil tape.
Claim 10
Dependent Claim
15 words
A blasting nozzle as defined in claim 4, wherein said element comprises a fiber bundle.
Claim 11
Dependent Claim
18 words
A blasting nozzle as defined in claim 4, wherein said element comprises a bundle of irregularly folded material.
Claim 12
Dependent Claim
103 words
A process for preparing barren ground for producing vegetation thereon comprising the steps of forming a slurry mix of a planting soil, feeding said soil under pressure through an ejecting nozzle so that the flow of soil through said nozzle creates a zone of negative pressure thereat, introducing air at said zone of negative pressure; feeding a continuous strand element together with said air at said zone of negative pressure whereby said element is sucked into said zone of negative pressure to mix with said soil flowing through said ejecting nozzle, and layering said mixture of soil and strand element onto barren ground.
Claim 13
Dependent Claim
103 words
A process for preparing barren ground for producing vegetation thereon comprising the steps of forming a slurry mix of a planting soil, feeding said soil under pressure through an ejecting nozzle so that the flow of soil through said nozzle creates a zone of negative pressure thereat, introducing air at said zone of negative pressure; feeding a continuous strand element together with said air at said zone of negative pressure whereby said element is sucked into said zone of negative pressure to mix with said soil flowing through said ejecting nozzle, and layering said mixture of soil and strand element onto barren ground.
Claim 14
Dependent Claim
