FIELD: construction. ^ SUBSTANCE: pneumatic curb comprises external and internal shells of elastic material tightly fixed on base and installed one against each other at a fixed distance, nozzle of air suction installed in upper part of external shell. Main difference of suggested structure from analogs consists in the fact that external shell has a hydrophobic coat, and cavity produced between shells is filled with dry fiber-reinforced sand mix tempered in process of erection with a mortar of early-strength binder (for instance, laitance). ^ EFFECT: short-lived components are not used in structure subject to durable storage. ^ 1 cl, 2 dwg |
