THREE-DIMENSIONAL FRAME HAVING CELLULAR STRUCTURE FOR GROUND CONSOLIDATION (VARIANTS) AND BAND FOR FRAME PRODUCTION (VARIANTS) Russian patent published in 2008 - IPC E02D17/20 

FIELD: construction, particularly ground consolidation during road building on bases formed of structurally unstable grounds, for road, pit slope, river bank and hydraulic structure consolidation and so on.

SUBSTANCE: in both variants band is made of polymeric material and has cuts uniformly distributed at spaced apart locations along band length. The cuts are transversal to longer band edge. Each cut has depth equal to half of band width b_s±5%. Cut width is not less than band thickness. In the first variant another band half has depressions opposite to each cut. Each depression has depth h_d=(0.1÷0.2)b_s. Distance between extreme cuts and shorter band edge is equal to 0.2÷1.0 m. In the second variant orifices are formed from both sides of each cut and are located close to cut and to band edge. Two orifices are made opposite to said orifices and located near opposite band edge so that distance between extreme cuts and shorter band edge is equal to 0.2÷1.0 m. In both variants three-dimensional frame includes longitudinal and transversal polymeric bands, which define quadrangular, preferably rectangular, cells. Spacing between cut centers in longitudinal band is equal to or differs from that of transversal bands. Longitudinal bands are laid so that cuts face upwards and receive transversal bands, which are inserted in longitudinal ones so that their cuts face downwards and create joints. In the first variant three-dimensional frame comprises bands, which are made in accordance with the first band production variant. Polymeric strips are placed in longitudinal band depressions and are connected to transversal bands. Transversal band depressions receive polymeric strips fastened to longitudinal bands. In the second frame production variant band made in accordance with the second variant is used. Fastening members, which pivotally connect longitudinal and transversal bands with each other, are located in orifices made in upper three-dimensional frame part, namely in ones created in transversal and longitudinal bands near cuts of longitudinal bands, as well as in orifices made in lower three-dimensional frame part, namely in ones formed in transversal and longitudinal bands near transversal band cuts.

EFFECT: increased tensile strength of the band and decreased material consumption.
