An excavating pump apparatus and a pile installation apparatus having the same are disclosed. An excavating pump apparatus in accordance with an embodiment of the present invention may include: an excavation head being inserted into an inner space of a pile through an open hole opening the inner space of the pile and being configured to crush seafloor sediments and allow the crushed seafloor sediments to be flowed therein; an outlet conduit connected to the excavation head and being a channel for discharging the seafloor sediments flowed into the excavation head to an outside of the pile; and a pump configured to move the seafloor sediments through the outlet conduit by providing a pump pressure to the outlet conduit

An apparatus and a method for attenuating water pressure pulses generated during sea piling when a percussion mechanism is used, including the stage of driving at least one pile into an earth by a percussion mechanism, while along at least a part of its axial extension, the pile is surrounded by water and at least partly by a tubular outer sleeve; and at least one gas-filled space is provided between the inner periphery of the outer sleeve and the outer periphery of the pile. The apparatus includes mechanisms for providing the gas-filled space.

A noise-attenuating pile comprising a pile driving shoe, an outer tube that engages the pile driving shoe, and an inner member that extends through the outer tube and engages the pile driving shoe, wherein the pile is configured to be installed in the ground with either an impact driver or a vibratory driver that engages only the inner member. The inner member is rigidly connected to the driving shoe, and the outer tube is elastically connected to the driving shoe, such that vibrations from the outer tube is substantially isolated from vibrations in the driving shoe.

The rapid consolidation and compaction method comprises (i) first driving a hollow pipe, (ii) driving a pipe with a removable end plate after filling and compacting the sandy material in it, through the hollow pipe, to required depth, creating high excess pore-water pressures in the range of 50 to 300 KPa in clayey soils, (iv) pulling out the pipe section leaving behind the removable end plate and thereby installing porous displacement piles which allows dissipation of the excess pore-water pressures horizontally to the porous displacement pile, in which the excess water flows out vertically to the ground surface, and (v) the length of the drainage path is reduced to half the spacing between adjoining porous displacement piles, allowing rapid consolidation resulting in increase in density. Installing the porous displacement piles in the layer of loose to medium dense sand layer results in the instantaneous increase in its density.

The present invention belongs to the technical field of offshore wind power construction and particularly relates to a system and a method for sealing expanded polymer-based pile shoes for a jacket. The system comprises a jacket disposed on a seabed, several pile shoes arranged around a lower end of the jacket, and several steel pipe piles inserted into the seabed, wherein the steel pipe piles are inserted into the corresponding pile shoes. The system is characterized in that gaps between the pile shoes and the steel pipe piles are respectively filled with concrete and an expanded high polymer from top to bottom, an annular elastic diaphragm is further connected to the inner walls of the pile shoes, and the expanded polymer is wrapped by the elastic diaphragm, such that the expanded polymer is isolated from the steel pipe piles and the concrete.

This invention concerns a method of doing business which is combined with several scientific advancements of technological ingenuity that results in a novel way of doing business. It in fact teaches a “business method” which creates an innovative approach to obtain annual multi-billion dollar financial revenue as monthly rental income; which results from a rather large scale residential development community of 2000 dwelling units per 50 acre parcels; each parcel being developed upon heretofore 10,000 separately abandoned “Municipal Solid Waste” MSW landfill sites throughout the United States. These apartments are exclusively geared as rentals of a 1,020 square foot-two-bedroom apartment dwellings for only Covid-19 “First Responders” and military service personnel, for the unprecedented sum of just $800/month rent. Additionally, as a supplemental “business method” approach, this instant business model also teaches how to solve the nation's Municipal Solid Waste MSW disposal problems forever into the future as an ingenious viable solution into perpetuity. Moreover, it is further postulated within this business model that further collateral financial revenue automatically inures as a natural business consequence of the sheer necessary and vital purchase of construction materials needed herein, thus positioned as a leveraged-buyout; whereby this 76 billion dollar opportunity now becomes an integral adjunct to this unique business model by adopting a “Home Depot” type retail business concept structure as additional revenue sharing for this inventor's shareholders.
