FIELD: construction.
SUBSTANCE: invention relates to the field of ground construction, namely, to construction of foundations of buildings and structures, in particular, to flexible leave-in-place forms for solid foundations. The leave-in-place flexible form for a solid foundation comprises a closed reservoir for concrete with a filler neck. The specified reservoir for concrete is made of a tight rubberised material and has dimensions and configuration in the working condition of being fully filled with concrete as corresponding in plan to dimensions and configuration of solid plane foundations for buildings and structures. The reservoir for concrete along the perimeter is equipped with an additional form - a shaper of the external side wall of the solid foundation, which is made of a rubberised material in the form of a tight reservoir, with the possibility of its filling with liquid until pouring of concrete into its reservoir via the filler neck installed on the additional form. The specified reservoir of the additional form has on the cross section in the working condition a closed curved shape with a flat vertical wall in the area of coupling with the inner surface of the reservoir for concrete, on the upper part of which there is an air nozzle with a tap, made as capable of supplying or removing air in process of concrete pouring. The form is attached to the support surface by fixing elements.
EFFECT: expansion of functional capabilities due to manufacturing of a solid foundation of arbitrary shape with a flat surface and vertical walls, simplified technology of form assembly and reduced labour intensiveness of foundation manufacturing.
