Embodiment 1

[0034] 1) The site is flat.

[0035] The site is leveled to the design elevation, and when the site soil is leveled, use a road roller to roll back and forth until there is no trace. After the site is leveled, drainage should be done well.

[0036] 2) Make the arch groove.

[0037] Make an arch groove on the foundation soil 2, check the size after the arch groove is formed, and control the error within 10mm. After the arch groove is completed, the exposure time should be reduced as much as possible, and the sun, rain and water immersion should be strictly prevented to avoid deformation of the arch groove.

[0038] 3) Pour and pound the cushion.

[0039] C20 fine stone concrete is used as the cushion layer, and the thickness of the fine stone concrete cushion layer is 50cm, so as to eliminate the size error of the soil tire as much as possible in the cushion layer.

[0040] 4) Set up arch plate 1 formwork.

[0041] The radius of the arch plate 1 is the same as the column d...

Embodiment 2

[0059] 1) The site is flat.

[0060] The site is leveled to the design elevation, and when the site soil is leveled, use a road roller to roll back and forth until there is no trace. After the site is leveled, drainage should be done well.

[0061] 2) Make the arch groove.

[0062] Make an arch groove on the foundation soil 2, check the size after the arch groove is formed, and control the error within 10mm. After the arch groove is completed, the exposure time should be reduced as much as possible, and the sun, rain and water immersion should be strictly prevented to avoid deformation of the arch groove.

[0063] 3) Pour and pound the cushion.

[0064] C20 fine stone concrete is used as the cushion layer, and the thickness of the fine stone concrete cushion layer is 50cm, so as to eliminate the size error of the soil tire as much as possible in the cushion layer.

[0065] 4) Place the prefabricated arch 1.

[0066] The radius of the prefabricated prefabricated arch plate...

Abstract

The invention discloses an arch bar foundation the foundation plate of which comprises a plurality of arch bars with arch sections. As the arch bar shape of the arch bar foundation of the invention has better structural stiffness and better stability than the plate shape of the traditional foundation, capabilities of horizontal force resistance, slippage resistance, differential settlement reduction and the like of the foundation are improved. The invention also provides a construction method of the arch bar foundation, comprising the following steps: 1) leveling the land; 2) producing arch groves; 3) casting and pounding a cushion coat; 4) arranging an arch bar moulding board; 5) arranging a foundation beam moulding board; 6) binding the arch bar and foundation beam steel; 7) casting andpounding arch bar concrete; and 8) casting and pounding foundation beam concrete.

Description

technical field [0001] The invention relates to an arch slab foundation. It also relates to the construction method of the arch slab foundation. Background technique [0002] The arched slab structure is a simple space thin-walled structure, which bears the action of the space force system and has a short force transmission route. At present, the arched slab structure is mainly used for the upper structure. The common foundation structure adopts flat plate structure, which is simple in structure type, but its structural rigidity is worse than that of arched plate structure. In addition, the stability of the arch slab foundation is stronger than that of the flat structure, which can increase the ability of the foundation to resist horizontal force, resist slippage and reduce differential settlement. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for constructing an arched slab foundation, and the rigid...
