Abstract
Novel precast concrete boxes are disclosed which can be assembled together and/or with structural shapes disclosed in U.S. Pat. No. 5,697,736 to form waterfront structures such as seawalls, boathouses and the like. The boxes can be sized and proportioned so as to be conveniently assembled in such structures and to be easily transported via intermodal transportation media. Novel methods of waterborne transport and installation of the boxes are disclosed. Shellfish habitats based upon the boxes are also disclosed.
Claims35
In a precast concrete structural L-member having the shape of a modified letter “L” for constructing seawalls or bulkheads, said members comprising a vertical wall portion, a horizontal footer, a vertical key protruding below the footer and an angular splash plate protruding from said member directly opposite said footer, the improvement comprising:
- at least one substantially vertical passage penetrating said splash plate and said key, having an upper inlet and a lower outlet, to facilitate setting said L-member in place by use of a fluid comprising water under pressure emerging from the lower outlet of said passage.
A set of precast concrete boxes for construction of seawalls, breakwaters and other structures, each box having the form of a rectangular parallelepiped and enclosed on all sides, further comprising means for flooding same with water and for subsequently expelling said water using air pressure or pumping means, said set comprising a plurality of boxes having at least two different sizes and sets of proportions which are so dimensioned as to permit said boxes to be conveniently and efficiently shipped together by densely fitting into intermodal means of transportation and assembled together to form structures.
A set of intermodal precast concrete boxes for assembly into shoreline or underwater structures, each box having the form of a rectangular parallelepiped and having at least one dimension adapted to fit conveniently and densely into at least two transportation modes comprising truck trailers, rail cars, barges and container ships, the set comprising a plurality of boxes having at least two different combinations of dimensions and/or proportions, wherein the smaller boxes have at least one dimension which is a whole number fraction of the corresponding dimension of the largest box of said set.
A precast concrete bridge box for construction of structures, having the overall form of a rectangular parallelepiped with at least five surfaces completely enclosed, the sixth and bottom surface comprising the longest dimension of said box and the two longest side surfaces adjacent thereto being cut out to form at least one unobstructed channel sufficiently large to permit substantial water flow adjacent said sixth surface when it rests upon the ground.
