TECHNOLOGICAL COMPLEX FOR ERECTION OF HYDRAULIC ENGINEERING WORK Russian patent published in 2015 - IPC E02B3/06 E02B17/00 E01D21/00 

FIELD: construction.

SUBSTANCE: invention relates to devices for the performance of works in hydraulic engineering construction and can be used for erection of bridge pile foundations, platforms, transhipping complexes and berthing facilities in water areas. A technological complex for the erection of a hydraulic engineering work (HEW) comprises a working platform 1, a set of tools for its erection. The HEW includes the pile piers 2 with a grillage 3 mounted on them, made of slabs. The service platform 1 is designed in the form of a longitudinal horizontal building slipway, equipped with equipment and assembly elements for the installation of HEW. The set of tools for the erection of the HEW includes a lifting device, a device for mounting the pile supports of the HEW foundation with the section buildup of the HEW grillage openings and a module of final assembly works. The lifting device is designed as a crane for heavy loads 5. The device for mounting the pile supports includes an aligning frame 6, aligned by the crane 5 to the horizon on a design axis by length and width of the span, with an external conductor 7 mounted on it. One end of the aligning frame 6 is installed on a transverse metal girder 8 of the HEW span already mounted, and the second external end is installed on two pairs of support columns 9 and 10 provided with hydraulic actuators. The first pair of the support columns 9 is installed on the ground of bottom vertically, and the columns of the second pair 10 are installed at an angle of 15-20° to the vertical columns 9. The conductor 7 is provided with apertures 11 designed in the form of sleeves to arrange the pile piers 2 in the design position by means of the crane 5 with subsequent their immersion with precast shell to the desired depth into the ground of the bottom and by fixing with retainers disposed in the apertures of the conductor 7. At the upper ends of the pile piers 2 there is a transverse metal girder 8, mounted by the crane 5 and fixed by a weld joint. Metal orthotropic plates 4 are installed and fixed by weld joints on the transverse girders 8 of the HEW sections already mounted and remounted. At the ends of the transverse metal girder 8 of the HEW span already mounted, a pair of temporary support jacks for supporting the additional support pairs of columns 13 and fixed by a weld joint, is provided. The additional support pairs of columns 13 are designed integrally with the conductor frame 6 and arranged in pairs on its bottom side along the longitudinal beams 12 with a step in accordance with formula: l = L / (n + 1), where l - distance between the pairs of additional support columns, L - length of the conductor frame, n - number of pairs of additional support columns.

EFFECT: expansion of arsenal of hardware and trouble-free operation when changing the length of spans, reduction of construction terms and reduction of the work complexity.
