DEEP SOIL MIXING EQUIPMENT AND METHOD

FIELD OF TECHNOLOGY

This disclosure relates generally to mixing deep soil with a ground or floating based rig system with a single or multi-axial system. In one example embodiment methods, apparatus, and systems are described for deep soil mixing tools or rigs with a rotary axial design, namely with more than one axial mixing elements and associated structures.

BACKGROUND

Within many fields, notably within ground modification, ground improvement and soil stabilization, such as for excavation support, seepage control, bearing capacity improvement, settlement control, lateral resistance, subterranean wall support, mixing of soil, as well as many other varied ground modification methods, boring, excavation of soil or ground material and filling with a material such as a solidification material is necessary. To accomplish this, many varied equipment are necessitated, of which can become expensive, time consuming and logistically taxing. To accomplish the aforementioned, digging, boring or excavating soil, and filling the resulting bore, requires many man hours and increasingly numerous amounts of differing equipment, including equipment to bore or dig, equipment to excavate, equipment to fill, etc. Exacerbating this, is the location and environment that the ground modification usually exists in. Ground modification, more often than not, takes place in busy ports, construction yards, or other areas where space or access is limited. As well as this, many ground modification projects may include time sensitivity, such as for emergency soil modification in areas where erosion risk is great or other aspects such as underground seepage possess a threat, such as a dam or in a construction area. Having the numerous different type of machinery and equipment reach and be housed in the area to be modified may be difficult due to the remote or treacherous location or due to an overarching construction project where space is limited. As well as this, and more notably, subterranean modification and resulting subterranean structures have a need to be continuously created or in quick succession, especially between steps such as digging, excavating and filling, as in the structure of boring, especially below the water table, the bore may fill with undesirable liquid such as water or an undesirable slurry, such as mud, ruining the ability for solidification material to be efficient and provide strength. With current equipment, a quick succession of equipment becomes necessary, clogging the area and providing logistical problems, as equipment is changed in and out, which reduces efficiency or may not even be possible within the time constraints. This causes projects to become increasingly difficult and require complex and tedious planning and equipment logistics.

Thus, a system, apparatus or method is necessitated that is able to bore, excavate, mix and fill subterranean bores, in as little processes as possible, for a more efficient ability to provide ground modification.

SUMMARY

Disclosed are methods, apparatus, and systems that provide a deep soil modification tool or rig with an axial design, notably with more than one axial. The deep soil modification equipment may be able to bore or dig into any type of soil and in any environment in varied locations and for varied purposes. These may include for ground modification including load bearing capacity improvement, settlement control such as within areas with underlying water tables, lateral resistance increases, liquefaction mitigation in areas where slurry or other underground areas may be undesirable for a purpose.

The method apparatus or systems may be housed on an external structure of which may be land based such as a crane, or water based such as a floating platform or ship, such as a barge. The ground modification rig may be of any height and design, but specifically may include multiple rotary axials. The axials may be housed in a relation between the ground and crane as to be able to be lowered and raised in relation to the ground, water, or intended modification location. As such, the apparatus, which may be connected to a structure such as a crane, at a plurality of different points, both for physical support as well as providing a basis for electrical connections or control connections, of which also may be wireless, to an operator housed in the structure, or in a remote control area. The ground modification apparatus may be of any height or width, and be lowered or raised through any method such as a cantilever, pulley or other system or method of raising or lower the axial system. The axial system, may be housed wherein there is one axial, or more the one axial, arranged in line, or other arrangement such as a square or rectangular arrangement, and so that each axial may rotate independently of each other. The axials, may connect directly such as a direct drive, through a transmission or gear reduction, or through another method such as a continuously variable transmission to a motor system, of which each axial may have a sole corresponding motor, or multiple axials may share a motor, and in any combination. With the preferred embodiment, each axial having a corresponding motor, of which is connected to a generator mounted on the structure, or in a remote location of which allows the axials to be driven so they rotate.

The axials may be spun in any direction so that the axials may provide the most efficient work, such as rotating clockwise in conjunction with an end bit that most efficiently bores in the clockwise direction. The axials may be of any design and may be broken into sections. Along the length of each axial and each section may be different extrusions, bits or designs for a purpose such as an auger screw design or smooth side cylinder for one section of which aides in the boring and mixing capabilities of the device. For instance the top section may be an augur screw design with helps mix and excavate soil out of the bore hole. The lowest section may be a bit, or special purpose section. The special purpose section bit, may be broken up into sub-sections for specific uses, and the design may change by the use, soil, environment etc. The lower sub-section of the bit, may be of a design that breaks through rock, or provides for a better mixing ability such as to granulate the soil, or make the soil easier to be excavated. Each section may couple or key together through any means such as a corresponding extrusion in one section and recess in another in which the extrusion keys into the recess such as a hex design, of which may transfer torque or rotation further along the axial.

The bits may encompass further extrusions, to further mix the spoil, granulate the soil or otherwise breakup the soil. The bit section may have an opening such as a port or hole of which a material such as solidification material, water or other material such as a slurry may be introduced to the hole being bored. This material such as a cement slurry, can backfill the bore and be mixed with soils, to provide for ground modification and improvement as well a strength for load dispersal. The material, which may also be water or another lubrication material, such as a simple mud slurry, may aide in the excavation and boring. There may be a plurality of ports of which material is deposited. The axial along its interior length, may be hollow to allow the material to flow from a source, of which may be connected in any method, such as a flexible hose to the structure and through the use of a joint to allow the axial to rotating while not binding with the hose. The slurry may be introduced at the top of the axial, providing a simple gravity feed for the material to exit out of the holes in the bottom section bit area. There may also be other methods of which the material is introduced, such as positive pressure designs and other various methods.

Any section may be provided with a span of material between axials, such as a cross brace, that provides support. The axials in the preferred embodiment may be aligned four wide and in a manner where the bore holed may overlap. The overlapping axials may also be arranged in a way wherein their extrusions or screws do not bind or otherwise interfere with each other while still providing overlapping coverage or boring area.
