Based on the size of the reservoir, I calculated the dimensions of the bridge. The distance between the banks of our pond is 1.3 m. Therefore, the length of the bridge is 1.6 m, and the width is 65 cm..
Elements for lateral «bearing» supports were cut out of four boards 1, b m long. Sections of boards were pulled in pairs on long screws — two arcs were obtained. They were sanded and treated with wood preservative.
The grooved floorboard was sawn into pieces 65 cm long. The longitudinal ends were slightly obliquely cleaned with a plane, so that when laying the boards end-to-end, not in a plane, but at an angle (the bridge is humped!) There was no gap between them.
Between the side support arcs, taking into account the radius of curvature, the bars — «steps» were fixed. «Transverse» boards were laid on top and screwed to the bars and side arcs using self-tapping screws.
We sawed a beam for the handrail (8 pcs. 1 m each), screwed the posts to the side arches. On the upper edge of the racks, a thin strip for the screed was launched, bending it and fixing it with self-tapping screws.
We prepared a place for the installation of the bridge when the foundation pit was concreted — on both sides of the pond, a brick foundation was provided in the form of steps. They put roofing material on them for waterproofing and threw a bridge over the isthmus of the pond.
For stability, side supports were made. From below, pieces of steel profile were attached to them so that the wood of the supports did not touch the ground and did not rot. And then the profile was concreted into the ground.
The bridge was completely painted, first with protective impregnation, then decorative, the lower part of the bridge was additionally treated with Kuzbass — varnish.
