Abstract
The utility model provides a silo foundation. The silo foundation comprises a plurality of foundation piles (1) and a bearing platform (2) fixed on the top of the foundation piles (1), wherein the bearing capacity of the foundation piles (1) distributed in the middle of the bearing platform (2) is greater than that of the foundation piles (1) distributed on the circumferential part of the bearing platform (2). Because the bearing capacity of the foundation piles (1) distributed in the middle of the bearing platform (2) is greater than that of the foundation piles (1) distributed on the circumferential part of the bearing platform (2), non-uniform settling of the bearing platform (2) can be relieved even under the condition that the load in the middle of a silo is greater than that of the circumferential part, and a pile top counterforce can be distributed on the foundation piles (1) as uniformly as possible.
Description
Technical field
The utility model relates to silo, particularly, relates to a kind of silo ground.
Background technology
Silo is for the warehouse of storing loose unpacked material, is divided into agriculture silo and industrial silo two large classes.The agricultural silo is used for having grain in reserve, feed equigranular and granular material; The industry silo is used for storing the loose unpacked materials such as coke, cement, salt, sugar.Because the mechanization silo can shorten the loading and unloading flow process of material, reduce operation and maintenance cost, eliminate heavy packed operation, be conducive to mechanization, automated job, so little by little be promoted and use at agriculture field and industrial circle.
Existing silo ground spaces out usually according to the restriction of foundation pile minimum spacing, and even, isometric, equal diameter lays out pile, and mainly adjusts the uniformity of foundation pile counter-force by the stiffness contribution of equal thickness cushion cap.Along with the superstructure load increases, cushion cap is more and more thicker, and size is also increasing.Under above-mentioned design principles, even under equally distributed load action, the cushion cap sedimentation also is, and butterfly sedimentation broad in the middle, that periphery is little distributes, and stake top counter-force is the shape of a saddle that interior stake is large, skirt piles are little and distributes.Because silo is commonly used to load heavier material, thus the load of silo mid portion usually greater than the load of peripheral part, thereby cause above-mentioned phenomenon even more serious.
The utility model content
The purpose of this utility model provides a kind of silo ground, and this silo ground can be alleviated the differential settlement of cushion cap.
To achieve these goals, the utility model provides a kind of silo ground, this silo ground comprises the stake of many foundation and is fixed on the cushion cap at described foundation pile top, wherein, be distributed in the bearing capacity of described foundation pile of described cushion cap mid portion greater than the bearing capacity of the described foundation pile that is distributed in described cushion cap peripheral part.
Preferably, described cushion cap has the first boss, and this first boss is arranged on the soffit of peripheral part of described cushion cap, is provided with first group of foundation pile below described the first boss.
Preferably, described cushion cap also has the second boss, and this second boss is arranged on the soffit of mid portion of described cushion cap, is provided with second group of foundation pile below described the second boss.
Preferably, the distribution density of described second group of foundation pile is greater than the distribution density of described first group of foundation pile.
Preferably, in described second group of foundation pile the cross-sectional area of every foundation stake of at least a portion foundation pile all greater than the cross-sectional area of every foundation stake in described first group of foundation pile.
Preferably, the cross-sectional area of all foundation piles all equates in described first group of foundation pile, the cross-sectional area of all foundation piles all equates in described second group of foundation pile, and in described second group of foundation pile the cross-sectional area of single foundation pile greater than the cross-sectional area of single foundation pile in described first group of foundation pile.
Preferably, described the second boss is positioned at the position, middle of described cushion cap, described cushion cap also has the 3rd boss, the 3rd boss is arranged on the soffit of mid portion of described cushion cap and between described the first boss and the second boss, is provided with the 3rd group of foundation pile below described the 3rd boss.
Preferably, the distribution density of described the 3rd group of foundation pile is greater than the distribution density of described first group of foundation pile and less than the distribution density of described second group of foundation pile.
Preferably, in described the 3rd group of foundation pile cross-sectional area of every foundation stake of at least a portion foundation pile all greater than the cross-sectional area of every foundation stake in described first group of foundation pile and all less than the cross-sectional area of every foundation stake in described second group of foundation pile.
Preferably, the cross-sectional area of all foundation piles all equates in described first group of foundation pile, the cross-sectional area of all foundation piles all equates in described second group of foundation pile, the cross-sectional area of all foundation piles all equates in described the 3rd group of foundation pile, and in described the 3rd group of foundation pile cross-sectional area of single foundation pile greater than the cross-sectional area of single foundation pile in described first group of foundation pile less than the cross-sectional area of single foundation pile in described second group of foundation pile.
Preferably, described the first boss is annular, and described the second boss is rectangle, and described the 3rd boss is two, the both sides that these two the 3rd boss are strip and lay respectively at described the second boss.
Owing to being distributed in the bearing capacity of described foundation pile of described cushion cap mid portion greater than the bearing capacity of the described foundation pile that is distributed in described cushion cap peripheral part, even so in the situation of load greater than the load of peripheral part of silo mid portion, also can alleviate the differential settlement of cushion cap, a top counter-force can be tried one's best distribute at foundation pile equably.
