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.

A stem wall bracket comprising a horizontal member, a short vertical member extending downward from a first edge of the horizontal member, and a long vertical member extending downward from a second edge of the horizontal member, where the first edge is opposite the second edge. The stem wall bracket further comprises a pin holder configured to extend through a hole in the horizontal member. The pin holder comprises a vertical portion and a horizontal portion extending from the vertical portion, where the horizontal portion is configured to hold a horizontally oriented rebar. The short vertical member and long vertical member further comprise a plurality of holes to allow a first and second form board to be removably attached using a plurality of fasteners.

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.

A foundation for wind turbine towers of the type used to support both metal towers and concrete towers of wind turbines that uses precast concrete or metal beams, combined with small footings concreted in situ, the beams being structurally connected at the central part of the foundation by the elements of connection and of support of the tower is disclosed. The invention affords the main advantage of achieving a notable reduction in the volume of materials used, both concrete and rebar, with a great reduction in assembly time and the consequent great economic savings as well as its ease of adaptation to different terrains is presented.

A caisson or casing 107 for installing a sheet 102/103 into a ground or underwater location, the caisson 107 having a shaped wall 107.1, which is open for a predetermined length and is adapted to receive and connect to an excavation means 3 within the confines of the caisson or casing 107. In at least one embodiment, the system includes a drilling assembly 3 for insertion of a caisson or casing 1, the drilling assembly 3 having one or more expanding drill bits 4 which are adapted to be driven by a drilling or rotation motive device 5, the expanding drill bits 4 being adapted to be arranged with respect to the caisson or casing 1 in use, so as form a hole or bore which substantially conforms to, or substantially overlaps with, the shape of the caisson or casing 1.

The invention relates to a foundation engineering machine and a method for producing a trench in the ground with a foundation engineering machine having a substantially vertical mast, a diaphragm wall apparatus which is displaceably supported in the longitudinal direction of the mast for producing a trench in the ground, and a bar-shaped holding means, at the lower end of which the diaphragm wall apparatus is mounted and with which the diaphragm wall apparatus is linearly displaceable along the mast. According to the invention provision is made in that on the mast an upper first clamping sledge with a first clamping means for releasably clamping the bar-shaped holding means and a lower second clamping sledge with a second clamping means for releasably clamping the bar-shaped holding means are movably supported and the first clamping sledge and the second clamping sledge are movable relative to each other and in that the lower second clamping sledge is provided with a connecting means for mounting an additional lifting device which is arranged on the ground and with which a force can be applied in the longitudinal direction onto the second sledge.

A modular slab, slab system, piles and methods of use thereof are described along with specific applications and methods of manufacture. The slab or slab system may be pre-insulated and pre-finished before being assembled on site. The slab system may be advantageous to use as a replacement for traditional in-situ poured building foundations. The slab system may also have uses in other fields such as for floors, roads, bridges, pavements/side walks and other civil and structural applications.

A novel wind turbine, the tower of which ending with three legs and which is also anchored to the ground by means of a characteristic anchoring system depending on the type of existing soil. It is anchored on conventional rock soil with a pile foundation, it is anchored in a hard-rock soil with an anchor-rock foundation, it is anchored in a non-rocky soil with a gravitational foundation and it is anchored on clayey or swampy soil with a gravitational foundation reinforced with piles.

A device that compensates for abrupt variations in fluid flow rate for a pump line is described. One or more aspects pertain to a system to accomplish automated in-situ placement of a concrete wall or embankment, where a fluid concrete is pumped into place, consolidated, and screeded to a finished surface, with remotely controlled or automated equipment.
