Abstract
The invention relates to a method for constructing anti-deformation building in sink area. First, laying clay layer or sand underlay layer when the dig depth has reached preset depth; layering and compressing; constructing rigid or flexible base above the clay layer or sand underlay layer; then arranging sliding layer; building basic circular beam above the sliding layer; at last constructing upper wall above the basic circular beam. The invention can effectively improve the whole rigidity and strength of building to restrict the sink, incline, curve and the additional stress generated by horizontal deformation of ground; therefore, it can confirm the safety of building with simple operation, lower cost, less accommodation of infield, and practicability.
Description
One, technical field
The present invention relates to construction method for deformation resistant building foundation in subsidence area, be particularly useful for the mine worked-out section newly constructed house, also be applicable to the reinforcing of above goaf existing building thing.
Two, background technology
Coal is the main energy sources of China, and in the primary energy consumption of China, coal accounts for about 70%.Because coal is after underground extraction, its top covering layer loses support, causes that the above goaf face of land produces mobile and distortion.Move and the distortion on the face of land directly have influence on the basis of building, thereby cause building to destroy.
In recent years, since the minimizing of underground storage, the expansion of underground mining scope, and the limit of mining in the many mining areas of China extends to below the intensive village and city gradually, contradiction between mine underground mining and the ground people's normal life is more and more outstanding, has a strong impact on the sustainable development in mining area; On the other hand, along with expanding economy, the increasing of population, the activity space that people live increases gradually.Because the fundamental realities of the country that China has a large population and a few land, many mining areas are exactly mining collapse area except that basic farmland, and carrying out building construction at mining collapse area has become inevitable.But carry out building construction at mining collapse area and have potential safety hazard, and only adopt at present the mining measure that reduces surface deformable to be difficult to guarantee the safety of above ground structure, therefore studying mining subsidence has become current urgency problem to be solved to the damage and the protection thereof of building.
Three, summary of the invention
In view of the deficiency that prior art exists, the purpose of this invention is to provide a kind of simple in structurely, resistance capacity to deformation is strong, and is effective, the deformation resis tant structure basis that cost is low.
Construction method for deformation resistant building foundation in subsidence area of the present invention:
Step poly-one: the excavation ground reaches projected depth in the subsidence area, lays argillic horizon or sand cushion and compaction in layers on ground;
Step poly-two: construction basis on argillic horizon or sand cushion;
Step poly-three: lay sliding layer on basic top;
Step poly-four: the foundation ring girder of above sliding layer, constructing, on foundation ring girder, build the top body of wall then by laying bricks or stones.
Described sliding layer adopts asphalt felt or malthoid sandwich material; Rigid foundation can be adopted in the basis, also can adopt flexible foundation, and rigid foundation is with free stone masonry, brick build or plain concrete is built and formed; Flexible foundation is built with steel concrete and is formed.In each unit scope of building, sliding layer is provided with on the plane on whole basis, same absolute altitude upper edge.
Construction method for deformation resistant building foundation in subsidence area of the present invention adopts flexible measures such as sand cushion and horizontal slip layer can effectively absorb the additional forces that face of land horizontal distortion causes, has increased the integral rigidity and the intensity of building effectively.These measures have improved the resistance to deformation and the shock resistance of building effectively; protected building effectively; can save a large amount of land resources; take to eliminate the flexible measure of distortion and the rigidity measure of resistance to deformation; can be in the subsidence area or the safe and reliable deformation resis tant structure of the mining area construction that will exploit from now on; reach the sustainable development that takies, makes things convenient for mining area life of farmers, maintenance mine of saving land resources, reducing the arable land; have higher economy and society benefit, and have practicality widely.
Four, figure explanation
Accompanying drawing is deformation resis tant structure foundation structure figure of the present invention.
Among the figure: 1. ground, 2. clay or sand cushion, 3. basis, 4. sliding layer, 5. foundation ring girder, 6. top body of wall, 7. backfill.
Five, the specific embodiment.
Below in conjunction with accompanying drawing one embodiment of the present of invention are further described:
Construction method for deformation resistant building foundation in subsidence area of the present invention: at first reach projected depth according to designing requirement excavation ground 1, adopt clay or medium sand construction clay or sand cushion 2 then, adopt the thickness of clay liner or sand cushion should not be lower than 1000mm and 500mm, and answer compaction in layers, the basis 3 of constructing successively again.Rigid foundation or flexible foundation 3 can be adopted in the basis, and rigid foundation can be with free stone masonry, brick build or plain concrete is built and formed; Flexible foundation can be built with steel concrete and be formed.Lay sliding layer 4 on basis 3, construction foundation ring girder 5 is built top body of wall 6 then by laying bricks or stones on foundation ring girder 5 above sliding layer 4, and the construction flooring is with backfill 7 filling foundation ditches, until all structures and the building operations of finishing building.In each unit scope of building, whole basic 3 plane is provided with sliding layer 4 in same absolute altitude upper edge, sliding layer is as a kind of flexible measure of earthquake-proof influence, and sliding layer 4 adopts asphalt felt or malthoid sandwich material, and sandwich material can adopt graphite powder, mica sheet.Whole building foundation is made of the clay on ground 1, the ground 1 or sand cushion 2, basis 3, sliding layer 4, ground collar tie beam 5 and top body of wall 6.
