EXCAVATION AND GROUND STRUCTURE FORMATION METHOD AND DEVICE (VARIANTS), AS WELL AS SAW SUPPORT AND BAR CHAIN Russian patent published in 2008 - IPC E02F3/00 

FIELD: construction, particularly surface and underground construction, ground consolidation and waterproofing operations.

SUBSTANCE: production method involves using stone-crushing bar and rope mechanisms to excavate ground, to create forms and drainage, to erect foundations, to produce wall materials, to erect building structures, gutters, manifolds, wells, buried structures, to consolidate and reinforce ground. Also disclosed are modernization variants and structural production, which provides structure creation in planes having irregular shapes. Erection methods are retaining wall, drilling-and-mixing, injection, form creation, separate concreting and cast-in-place molding technology. Several structures may be formed with the use of the same equipment.

EFFECT: increased excavation efficiency and capacity, possibility to create thin-walled three-dimensional structures with crossing planes.
