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.
Claims28
An integrated shoreline reinforcement system comprising at least one row of ballasted precast concrete boxes approximately parallel to said shoreline, with at least two rows of ballasted concrete boxes attached approximately perpendicular to said at least one row of boxes paralleling said shoreline to form groins and define horizontal beach spaces between adjacent groins, wherein the horizontal beach spaces between said groins are covered with filter cloth and concrete mat sections laid thereon and wherein at least one precast inverted “T” member is attached to the seaward end of each of said groins and the upper seaward corner of the endmost seaward “T” member of each of said groins is bevelled to prevent damage to boats in their vicinity.
A precast concrete box for construction of seawalls, breakwaters and other structures, which has the form of a rectangular parallelepiped, and comprises at least two separate inner compartments of substantially equal volume which can be independently flooded or blown, enclosed on all sides and comprising means for flooding same with water and for subsequently expelling said water using air pressure or pumping means.
A precast concrete box for construction of seawalls, breakwaters and other shoreline structures, enclosed on all sides and comprising means for flooding same with water and for subsequently expelling said water using drains, air pressure or pumping means, comprising at least two separate inner compartments which can be independently flooded or blown, further comprising valve means adapted to equalize at least one of air pressure and liquid contents between said separate compartments.
A set of intermodal precast concrete boxes for assembly into structures, each box having the form of a rectangular parallelepiped and having at least one dimension adapted to fit conveniently into at least one transportation mode 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 defining larger and smaller boxes 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 and each box is completely enclosed except for mechanical means for flooding and sinking and blowing and surfacing said boxes from underwater.
A precast concrete bridge box having the overall form of a rectangular parallelepiped with at least five surfaces completely enclosed, the sixth surface comprising the longest dimension of said box and the two longest surfaces adjacent thereto being partially cut out to form an unobstructed channel sufficiently large to permit substantial water flow adjacent said sixth surface when it rests upon the ground, which is fitted with anti-scour means attached to the lower wall on at least one side which is to be exposed to water.
A precast concrete bridge box having the overall form of a rectangular parallelepiped with at least five surfaces completely enclosed, the sixth surface comprising the longest dimension of said box and the two longest surfaces adjacent thereto being partially cut out to foam an unobstructed channel sufficiently large to permit substantial water flow adjacent said sixth surface when it rests upon toe ground, further comprising at least one conduit passage cast into said box substantially perpendicular to said channel and connecting two surfaces of said box.
