Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
136 words
IN A PROCESS OF LINING THE WALLS OF EXCAVATIONS, SAID PROCESS COMPRISING FORMING INJECTION CONDUITS ALONG THE WALLS OF AN EXCAVATION, INSERTING A REINFORCING TUBE INTO THE EXCAVATION IN SPACED RELATION WITH THE WALLS THEREOF POURING CONCRETE BETWEEN THE TUBE AND EXCAVATION WALLS SUCH THAT THE REINFORCING TUBE AND CONCRETE UPON SETTLING FORM A LINING BODY, CONVEYING PRESSURE FLUID THROUGH THE INJECTION CONDUITS AND DISCHARGING THE FLUID BETWEEN THE EXCAVATION WALLS AND THE OUTER SURFACE OF THE LINING BODY TO FORM A GAP THEREBETWEEN AND EXERT RADIALLY INWARD PRESSURE ON THE LINING BODY AND RADIALLY OUTWARD PRESSURE ON THE WALLS OF THE EXCAVATION, AND THEN INTRODUCING A SETTABLE SUBSTANCE INTO THE GAP THUS FORMED SO THAT SAID SUBSTANCE SETS IN SAID GAP AND MAINTAINS THE PRESSURE ON THE WALLS OF THE EXCAVATION AND THE LINING BODY.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
110 words
APPARATUS FOR LINING THE WALLS OF AN EXCAVATION COMPRISING A PLURALITY OF ENDWISE ABUTTING LINING BODIES TIGHTLY FITTED WITHIN THE WALLS OF SUCH ESCAVATION, INJECTION CONDUITS EXTENDING LENGTHWISE OF SAID BODIES BETWEEN THE WALLS OF THE EXCAVATION AND THE BODIES AND HAVING SPACED OUTLET OPENINGS FOR DISCHARGING SETTABLE MATERIAL UNDER PRESSURE BETWEEN THE BODIES AND THE WALL TO FORM A GAP BETWEEN THE WALLS AND SAID BODIES AND EXERT PRESSURE ON THE WALL AND THE LINING BODIES, EACH LINING BODY BEING CONSTITUTED BY A CONCRETE RING WITH A REINFORCING TUBE ON THE INNER SURFACE THEREOF, AND FURTHER INJECTION CONDUITS MOUNTED ON THE REINFORCING TUBE BETWEEN THE TUBE AND CONCRETE RING.
