During the past experienced silo work, we installed many silos from 50ton, 100ton, 200ton, 500ton, up to 5000ton, we have meet many question from customer, the most frequent question is the silo installation. Following is some brief introduction of the bolted silo installation for reference:
2. Connect the first layer of silo wall plate (according to the design thickness). Based on the design of the connecting method connect by screw holes and silo top stiffening ring. Fixed installation of lifting frame according to foundation design.
3. Install silo roof plate and ladder, silo roof man hole, air hole, guardrail. The flange to connect bolt must be paint waterproof glue for preventing rain enter to silo when rainy season. If need silo catwalk between two or more silos, we should install transit channel steel, catwalk steel frame, diagonal bracing and cross arm on the catwalk frame position in the first layer plate of silo roof, in order to install silo catwalk
4.According to designed thickness of silo plate and stiffener, install them layer by layer from up and down. It requests top layer outside, and under layer inside when connected silo plate. Fixed the stiffeners by splint. The bolt screwing strength shall meet the request, should not miss bolt or unfasten phenomenon, The bolt must be with waterproof rubber mat, all of gaps between plates shall be put sealing joint strip before connection and guarantee same thickness.
5. According to the designed steel plate layers and thickness install the silo from up to bottom layer by layer, meanwhile install the silo outside ladder. After installation the silo, each stiffener shall be corresponding to base foundation embedded part ( or steel cone connecting plate), strictly locate according to designed center distance. When finished perpendicularity adjustment, to weld the stiffener and embedded part, it requests complete real welding which conform to national regulation, not allowed spot welding, solder skips and not knock on dregs.
