The deteriorated piling is severed below the mud line and a cast-in-place concrete column is positioned between the severed piling and the overhead supporting member. Any required length of column is formed by suspending a preformed base section in water over the severed piling, securing a form member to the top edge of the base section, spraying quick-setting concrete over the form member, which sets in seconds, and adding progressive additions of form member and concrete while lowering the hollow column into place over the severed piling until contact is made with the overhead structure. An integral, hollow concrete column is formed functioning as a load-bearing piling.，下面是Method of replacing piling专利的具体信息内容。
1. A method of providing a load-bearing, cast-in-situ concrete piling, comprising: providing a concrete base member adapted to be secured to a sound bottom piling stub whose upper end is just below the mud line; securing an elongated, hollow, concrete form tube to the top of the base member; applying a layer of quick-setting concrete completely over the outer surface of the form tube and its intersection with the base member of sufficient thickness to form a hollow, loadbearing concrete column; suspending the base member and hollow column in the water above and over the piling stub; lowering the integral base and column into contact with the piling stub; securing the base to the piling stub; and securing the upper end of the column to an overhead support member, the elongated, hollow, concrete form tube extending from the base member to just below the overhead member so as to form a continuous load-bearing concrete column extending from the piling stub to just below the overhead member.
2. The method of claim 1 wherein the column is secured to the overhead member by applying a layer of quick-setting concrete around the intersection of the concrete column and the overhead member.
3. A method of providing a load-bearing, cast-in-situ concrete piling as a replacement for deteriorated piling, comprising: severing and removing the deteriorated section of a piling between the mud line and the overhead member with which the deteriorated piling has been in contact, leaving a sound bottom piling stub; suspending a precast concrete base member adapted to fit over and be secured to the piling stub in the water above and over the piling stub; securing a first elongated, tubular concrete form to the upper portion of the base member; applying a layer of quick-setting concrete completely over the outer surface of the form tube and its intersection with the base member of sufficient thickness to form a hollow, load-bearing concrete column integral with the base, the layer of concrete terminating just below the upper terminating edge of the tubular form; lowering the base member and the integral, upwardly extending, hollow concrete column into contact with the piling stub of the severed section while progressively securing additional tubular concrete forms to the upper terminating edges of each successive form with application of quick-setting concrete completely around the outer surfaces of each additional form so as to form a continuous, load-bearing, hollow concrete column extending from the stub to the overhead member, and securing the concrete column to the stub and overhead member.
4. The method of claim 3 wherein the base member and hollow column are secured by filling the area surrounding the base and any voids between the base member and the stub of the piling with concrete.
5. The method of claim 3 wherein the concrete form tube consists of a non-metallic, laminated fiber sheet impregnated with bitumen.
6. A method of providing a load-bearing, cast-in-situ concrete column as a replacement for a deteriorated piling, comprising: severing and removing the deteriorated section of a piling between the mud line and an overhead member with which the deteriorated piling has been in load-bearing contact so as to leave a sound bottom piling stub; positioning a floating working platform in the water over and above the piling stub; suspending a prefabricated, steel-reinforced concrete base member in the water adjacent the platform over the piling stub, the base member having a lower section adapted to fit over and be secured to the piling stub and an upper, reinforced, hollow concrete column extending above the waterline; securing a first elongated, tubular concrete form to the upper terminating edge of the column of the base member; securing a section of concrete reinforcing material around and spaced from the tubular form; applying a continuous layer of quick-setting concrete completely around the outer surface of the concrete form and reinforcing material sufficient in thickness to form a load-bearing structure, the concrete layer terminating just below the upper terminating edge of the tubular form; lowering the formed concrete column and base member into the water until contact of the base is made with the piling stub while progressively securing, between the waterline and the overhead member, successive tubular forms to the upper terminating edge portion of each succeeding form with application of reinforcing material and a layer of quick-setting concrete completely around the outer surface of each succeeding form to form a continuous, hollow, load-bearing concrete column extending between the piling stub and the overhead member; and securing the concrete column to the piling stub and overhead member.
7. The method of claim 5 including filling the hollow interior of the concrete column from the bottom up with concrete.
8. The method of claim 5 wherein the concrete column is secured to the overhead member by applying a layer of quick-setting concrete around the intersection of the concrete column with the overhead member.
9. A cast-in-situ concrete replacement piling extending between and in load-bearing contact with a sound piling stub and an overhead support member comprising: a concrete base member resting on the sound lower Section; a hollow concrete form tube extending upwardly to just below the overhead support member; and a layer of reinforced concrete completely surrounding the tubular form tube integral with the base and extending into load-bearing contact with the underside of the overhead member.
10. The piling of claim 9 wherein a vertical cross-section of the concrete base member exhibits a U-shaped configuration, the legs of the U adapted to fit over the piling stub and wherein the base member includes a concrete inlet port extending therethrough for injection of concrete to fill any voids between the base member and the piling stub.
