Abstract
The utility model discloses a deformation-resisting building foundation in a gob area. The deformation-resisting building foundation in the gob area solves the difficult problem of rebuilding deformation-resisting houses on the gob area on site. The deformation-resisting building foundation in the gob area comprises a building foundation body (1) and a cement mortar bedding cushion (3). A felt layer (2) is arranged between the building foundation body (1) and the cement mortar bedding cushion (3), and a broken stone cushion (4) is arranged under the cement mortar bedding cushion (3). The deformation-resisting building foundation in the gob area enables the building foundation body and structures at the upper portion of the building foundation body to well coordinate with a foundation by changing the building foundation. Thus, a building is prevented from being damaged.
Description
Technical field
The utility model relates to a kind of building foundation, particularly a kind of basis of the building of constructing on the ground of coal mine gob.
Background technology
Coal mining not only can cause the destruction of underground soil layer, and makes the minery above ground structure also be subject in various degree destruction.Changing the address builds a house to the land resources today in short supply of a kind of extravagant hope often, and rebuilding on the spot Antiwarp house on minery becomes major measure.The seam mining depression causes the earth's surface distortion, and then make subgrade reaction produce distortion, the basis has just lost mechanical balance with ground, causing building top structural mechanics balance destroys, destroying at first appears in the weak link in structure, releases energy, and then forms again new balance, and then the distortion aggravation, destroy further serious.The destruction essence of building is the result of building foundation and superstructure and ground self-control, can utilize the mechanism of building foundation and superstructure thereof and ground self-control to make up the building foundation at minery, become the at present heat subject of structure foundation area research.
Summary of the invention
The utility model provides a kind of Deformation Resisting Buildings Constructed on Goaf building foundation, has solved a difficult problem of rebuilding on the spot Antiwarp house on minery.
The utility model is to solve by the following technical programs above technical problem:
A kind of Deformation Resisting Buildings Constructed on Goaf building foundation comprises building foundation and cement mortar bedding cushion, is provided with the malthoid layer between building foundation and cement mortar bedding cushion, is arranged with hardcore bed at cement mortar bedding cushion.
The thickness of described cement mortar bedding cushion is 20 millimeters, and the thickness of described hardcore bed is 500 millimeters.
The utility model is by the basis that changes building building foundation and superstructure and ground thereof to be coordinated well, thereby avoids the destruction of building.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
A kind of Deformation Resisting Buildings Constructed on Goaf building foundation comprises building foundation 1 and cement mortar bedding cushion 3, is provided with malthoid layer 2 between building foundation 1 and cement mortar bedding cushion 3, is arranged with hardcore bed 4 at cement mortar bedding cushion 3.
The thickness of described cement mortar bedding cushion 3 is 20 millimeters, and the thickness of described hardcore bed 4 is 500 millimeters.
By the failure mechanism of building in mining area as can be known: the destruction of building is derived from the mining subsidence caused earth's surface distortion of minery, and Adopts measure is intended to extenuate, absorbs and resists this kind distortion in the design so, the essence in Here it is the injecting treatment of mining zone.The essence of this technology is that the guiding distortion is concentrated, and absorbs most of earth's surface deformation energy, improves the non-deformability of building.Artificial forms plane of weakness in building superstructure or foundation, adopt the earth's surface distortion that causes in order to absorption portion, or transmission and the expansion of blocking-up earth's surface distortion, make building have enough earth's surface distortion compliance, thereby reduce subsidiary stress in the structure and possible distortion.
Specific construction step of the present utility model is: at first, divide into the hardcore bed of 500 millimeters thick at the concrete cushion on basis, then, constructing concrete bed course on hardcore bed, at last, concrete cushion on the basis arranges the horizontal slip layer one, and the sliding layer way is to do in the cement mortar of 20 millimeters thick to spread 2 layers of malthoid.
Claims (2)
1. Deformation Resisting Buildings Constructed on Goaf building foundation, comprise building foundation (1) and cement mortar bedding cushion (3), it is characterized in that, between building foundation (1) and cement mortar bedding cushion (3), be provided with malthoid layer (2), be arranged with hardcore bed (4) at cement mortar bedding cushion (3).
2. a kind of Deformation Resisting Buildings Constructed on Goaf according to claim 1 building foundation is characterized in that the thickness of described cement mortar bedding cushion (3) is 20 millimeters, and the thickness of described hardcore bed (4) is 500 millimeters.
