BUILDING AND CONSTRUCTION ERECTING METHOD, AND DEVICE FOR METHOD'S IMPLEMENTATION Russian patent published in 2009 - IPC E02D27/00 

FIELD: construction industry.

SUBSTANCE: invention refers to construction industry and can be used for levelling non-uniform foundation settlements of buildings and constructions both during their construction and operation. Method of erecting the building/construction involves making of multi-layer foundation, as to height, with subsequent erection thereon of the building/construction above the foundation. Foundation is made by laying on the base of concrete bedding and by erecting thereabove along the surface area of the foundation of the specified number of monolithic or reinforced concrete load-carrying sections-plates with pre-forming of intermediate protective waterproofing layers and layers of reinforcement geosynthetic material above concrete bedding, thus forming an intermediate material layer with the specified parametres between them, which compensates foundation settlements. In load-carrying foundation plates throughout their thickness there formed are channels which are open on edges, and tubes are installed in them and have widening on lower ends and which are located in material layer compensating the foundation settlements, and preferably in plan in the places of maximum design settlements and deflections of the foundation, including under load-carrying supporting structural members of the building/construction - under columns and/or walls, and upper tube ends are arranged in access area; after that, the foundation along its perimetre and waterproofing is tightened. During erection and operation of the building/construction and/or during building works, including earth works near the building/construction, which cause settlements and/or tilts and/or deformations of foundation and/or building/construction, through upper tube ends there performed are staged and/or simultaneous injections of hardening material with specified characteristics into intermediate layer compensating the foundation settlements under excess pressure which is more than vertical specific pressure of the foundation on the base, which is determined by the calculation and/or as per the current measurement results of foundation settlements. After each injection is completed, tubes are cleaned and plugged in lower part, and then, plugged with plugs from above. Injections are stopped after the specified level of decreasing settlements and/or deformations of the building/construction is reached. After concrete bedding layer is laid, first, layer of reinforcing geosynthetic material is laid on the foundation material, thus forming the folds compensating its tension; granular material layer is laid on that material, on which there installed are the tubes equipped, as the widening, with flat external washers on lower end, and then waterproofing layer is laid above washers so that upper tube ends can pass through that layer. Places of tube passage through insulation are sealed, and upper tube ends are taken out above waterproofing at the distance providing their passage through total lengths of load-carrying sections-plates of the foundation at the level below the floor of the building/construction with the possibility of accessing them through inventory access holes made in the floor in order to tightly connect to them the actuator creating pressure in injected hardening material. Then the frame is made of reinforcement and framework is made, and the latter is filled with concrete; at that, sections-plates of the foundation in plan up to the construction frame made from reinforcement are divided with movement joints in the places of increased design stress at joints of the housings of the building/construction, which have different number of stories, and at joints of foundation plates divided with movement joints, prior to their erection, there formed in waterproofing layer are compensating folds in order to maintain its continuity at non-uniform settlements of neighbouring foundation plates of the building/construction parts with different number of stories. When the foundation is completed, its load-carrying sections-plates together with waterproofing are tightened along the perimetre. The device for implementing the method is also proposed.

EFFECT: reducing labour input and material consumption when building the foundation, increasing carrying capacity, decreasing tilts and deformations of erected building/construction, as well as providing continuity of waterproofing at non-uniform settlements of housings of the building/construction with different number of stories both during construction and operation.
