Abstract

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.

Description

The invention relates to the field of construction and can be used to correct uneven precipitation of the foundations of buildings, structures both during their construction and during operation.

Uneven precipitation of the foundations of buildings and structures is the main reason leading to disruption in the operation of elevator equipment, the appearance of deformations in the elements of the frame of structures, the appearance of cracks in the elements of the supporting structures, and their partial or complete failure.

A known method of repairing a building, structure [1], which includes cutting the foundation into sections with subsequent compression of the soil under these sections to reduce precipitation of the building, structure, by creating cavities between the foundation and the base and placing elastic containers in them with partially filling the cavities with a working medium, and the remaining volume of the hardening material and the supply of the working medium under pressure after hardening of the hardening material.

A disadvantage of the known solution lies in its low efficiency, and also in that it does not provide sufficient reliability to reduce precipitation, because when it is used, the base soils are compacted after the foundation precipitation has occurred, therefore, only those precipitations and heels that develop over time can be reduced, moreover, the known method is intended for single use.

A known method of leveling the foundation of a building, structure [2]. The method includes drilling vertical boreholes in the foundation slab through which thermoplastic material is injected into openings in the bottom of the foundation body, followed by partial extraction of the thermoplastic material and filling the cavities formed with bulk material.

A disadvantage of the known solution is that it does not provide sufficient reliability and efficiency when reducing precipitation, leveling banks, deformations and deflections of the foundation of a building, structure, because when using this method, the soil of the base is compacted, mainly after the precipitation of the foundation has occurred, therefore, it is possible to reduce only those precipitation and heels that develop over time.

The prototype of the invention in terms of the method essentially solved the problem and the number of common essential features is the method of construction of a building, structure [3].

The method provides for the implementation of a multilayer foundation in height, followed by the erection of the structure of the upper structure of the building, structure, the foundation being performed by laying on the concrete foundation and erecting on top of it one or more in height and / or area of monolithic and / or precast / or prefabricated reinforced concrete slabs with the preliminary formation of a waterproofing layer on top of the concrete preparation, and under the upper slab and / or slabs before it or their implementation, an intermediate layer of hardening material and between the layers of the reinforcing geosynthetics formed between the bottom and top of this layer, and the characteristics of the hardening material are determined by the dependence given in [3]. In the upper plates, over their entire thickness, channels are open that are open at the top and bottom with the installation of tubes in them, the lower ends of which have broadenings, which are placed in the intermediate layer, while the channels and tubes are preferably placed in plan in places of the greatest settlement and base deflections, in including under the supporting supporting structural elements of the building, structure, columns and / or walls, and the upper ends of the tubes are placed in the access zone, after which, along the perimeter of the foundation, the zone of the intermediate layer and / or hydrois foundation voltages are sealed, and during the construction and / or operation of the building, structure, and / or during construction, including earthworks near the building, structures causing precipitation and / or banks, and / or deformation of the power elements of the foundation and / or buildings, structures, through the upper ends of the tubes in the upper plate, stage-by-stage and / or simultaneous injection of the hardening material into the intermediate layer is performed with the formation of a gap and / or delamination in this layer and filling of the formed gap with injectable hardening m material under pressure exceeding the specific pressure of the foundation, structure, on the base, also determined by the dependence given in [3].

A disadvantage of the known solution is the complexity and material consumption of the construction of multilayer monolithic or prefabricated reinforced concrete intermediate plates between the base and the upper foundation plates, because the material consumption of such a foundation to ensure its strength is excessively large. Another drawback is the need for a significant strengthening of the foundation in areas of significant stress and strain both in the basement bearing plates and in the connecting structures of the upper structure at the junctions of the main building, structures with significantly higher number of storeys with extensions having significantly lower number of storeys, due to their unequal sediment both under its own weight during the construction process, and additionally from the payload during operation. The problem of reliability of the integrity of the waterproofing in the area of joints of load-bearing reinforced concrete slabs in terms of uneven foundation settlement has also not been solved.

The technical task of the present invention is to reduce the complexity and material consumption during the construction of the foundation, eliminating the possibility of unacceptable stresses and deformations both in the foundation and in the connecting elements of the building, structure, and in ensuring their integrity when aligning the rolls and deformations of the foundation, as well as the building, structure , both in the process of their construction and operation, and in ensuring the integrity of the waterproofing.

The technical problem posed in terms of the method of building a building, construction, is solved due to the fact that it provides for the implementation of a multilayer foundation with the subsequent construction of supra-foundation structures of a building, structure, and the foundation is performed by laying concrete preparation on the base and erecting one or more of it over the area more monolithic or precast monolithic and / or precast reinforced concrete bearing sections-slabs with the preliminary formation of intermediate protective layers of waterproofing and reinforcing geosynthetic material, with the formation between them of an intermediate compensating settlement of the basement of the material layer with the given parameters, while in the bearing foundation slabs, channels open to the bottom and top to form tubes widening at their lower ends, which are placed in plan preferably in places of the greatest settlement precipitation and foundation deflections, including under the supporting structural elements of the building, structure, columns and / or walls, the lower ends of the pipes OK is placed in the compensating layer of the material, and the upper ends of the tubes are placed in the access zone, after which the foundation along its perimeter and waterproofing are sealed, while during the construction and operation of the building, structure, and / or in the production of construction, including earthworks near the building, structure causing precipitation and / or banks, and / or deformation of the foundation and / or building, structure, through the upper ends of the tubes, stage-by-stage and / or simultaneous injections of hardening material with given characteristics in daily foundation layer compensating subsidence under excess pressure exceeding the vertical specific pressure of the foundation on the foundation, determined by calculation and / or according to the results of current measurements, foundation sediments, and at the end of each injection, the tubes are cleaned and tamped in the lower part, and then closed with plugs, and the injections stop after reaching a predetermined level of reduction of sediment and / or deformation of the building, structure, according to the invention on the prepared soil base after laying concrete on the preparations first lay a layer of reinforcing geosynthetic material with the formation of folds compensating for its stretching, lay a layer of granular material on this material, onto which tubes equipped as widening with flat outer washers at the lower end are installed, and then a waterproofing layer with the formed in it according to it is laid over the washers according to plan the holes so that the tubes pass through these holes, after which the places where the tubes exit through the insulation are sealed, and the upper ends of the tubes more than waterproofing to a distance that ensures that they pass the total thickness of the bearing sections of the foundation plates at a level below the floor of the building, structure, with the possibility of approaching them through inventory hatches formed in the floor, to tightly connect the actuator to them, creating pressure in the injected hardening material and then build the frame from the reinforcement and formwork, after which the formwork is poured with concrete, and the base section sections in the plan are separated by expansion joints in m before construction of the frame from the reinforcement There are high calculated stress state at the joints of buildings, structures with different number of storeys, and at the joints of foundation plates separated by expansion joints, compensating folds in the waterproofing layer are formed before they are erected to maintain its integrity in case of uneven precipitation of adjacent foundation plates of different-floor parts of the building, structures, at the same time, at the end of the construction of the foundation, its bearing sections-plates along the perimeter, together with waterproofing, are sealed.

Before laying the geosynthetic material on the concrete preparation, sand and / or granular material is added, and the folds in the layer of geosynthetic material and in the waterproofing layer are treated with anti-adhesive material, preventing them from sticking and gluing. Injections are repeated as necessary in the event of unacceptable additional precipitation, and / or rolls, and / or deformations of the foundations arising after the construction of the building, structure, due to additional deformations of the base.

The prototype of a device that implements the inventive method of building a building, structure, in essence is a device that implements a method of building a building, structure [3]. The device includes a multilayer foundation laid on a prepared soil foundation on which the structure of the building’s upper structure and structure is erected, the foundation layers consisting of sand and / or concrete foundation preparation, protective waterproofing and reinforcing layers of geosynthetic fabric, one or more in height and / or by the area of the supporting monolithic or reinforced concrete sections-slabs, as well as the layer compensating the settlement of the foundation with a filler with specified parameters, laid between the layers of geosynthetically fabric under the upper bearing plates, filled under pressure as the deformations, deflections and rolls of the foundation are fixed with hardening material with specified characteristics. In the upper bearing plates of the foundation, through channels are opened, open from above and below, with pipes running through them, mainly with expansion at the lower end, placed in plan in places of the greatest settlement precipitation and deflection of the foundation plates, including under the supporting structural components of the building, structure , - columns and / or walls. The lower ends of the tubes are in contact with the compensating layer, and the upper ends are passed through the basement bearing plates in places accessible for connection to inventory equipment to enable the hardening material to be pumped under pressure. The device is equipped with devices for cleaning the tubes after each injection, plugging the tubes in the lower part, as well as a sealed plug on top during their preservation, as well as devices for the hermetic connection to the inventory equipment making the injection.

A disadvantage of the known solution is the material consumption and the complexity of the construction of the intermediate bearing layers of the foundation in height, which slightly affects the strength of the main upper foundation plates and does not eliminate the possibility of unacceptable deformations of the foundation and the structure of buildings, structures, in the adjoining zones of multi-storey buildings, as well as the integrity of waterproofing at uneven precipitation of foundation slabs.

An object of the invention in terms of the device, as well as in the method part, is to reduce the complexity and material consumption during the construction of the foundation, eliminating the possibility of unacceptable deformations in the connecting power elements of both the foundation and in different-floor fragments of the building, structure, due to their uneven precipitation, as well as ensuring reliability and efficiency when leveling rolls and deformations, as well as the integrity of the foundation waterproofing, both during the construction of a building, structure, and in the process of their operation.

In the layer of geosynthetic fabric, folds compensating for its stretching and ensuring its integrity are formed, processed, as well as folds of waterproofing, with a material that prevents them from sticking and sticking. Pockets are formed at the exit points of the upper ends of the tubes in the slab sections for hermetically connecting injection equipment to the tubes, as well as for installing plugs that are simultaneously hatches that cover openings formed in the floor of the building or structure. Each of the tubes is equipped with a technological inventory swab made of an elastic material that prevents sticking to the tube material, which is installed in the lower part of the tube during their preservation in the intervals between injections, fixed on the lower end of the ramrod, the upper end of which protrudes from the top of the tube and is placed in the cavity, formed in the plug equipped with a sealing ring.
