Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. The components of embodiments of the present invention, as generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the present invention, presented in the accompanying drawings, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Examples
Referring to fig. 1 and 2, the present embodiment proposes an above-ground and underground unified storage structure 10, which includes a lower silo body 11 and an upper dome 12. The bin side wall 13 of the lower bin body 11 covers the pit wall 15 of a conical pit which is dug from the ground and has a large upper part and a small lower part, and the bin side wall 13 encloses a conical accommodating cavity 16. The upper dome 12 is an upwardly convex thin shell structure, such as provided in the form of a spherical shell. The upper dome 12 defines an upper receiving space 17. The upper dome 12 covers the upper end opening of the conical receiving cavity 16. The upper receiving space 17 communicates with the tapered receiving chamber 16. In this embodiment, the upper edge of the bin side wall 13 is provided with an annular base beam 18, and the upper dome 12 is supported and connected to the annular base beam 18.
The underground and overground combined storage warehouse structure 10 in the scheme can store more materials by fully utilizing the conical accommodating cavity 16 which is limited by the structure and is positioned underground and the upper accommodating space 17 on the ground. Moreover, the supporting force of the pit wall 15 of the underground part conical pit to the side wall 13 of the silo and the pressure of the material stored in the conical accommodating cavity 16 are balanced and offset, the requirement on the self structure bearing capacity of the side wall 13 of the silo is reduced, and no obvious internal force effect is generated in the structure of the side wall 13 of the silo. The structure with lower strength and bearing capacity can be used for storing and supporting more materials, and the stress condition of the storage structure is good. In addition, the temperature of the underground part is constant, which is beneficial to the storage of materials.
The conical shaped pit and the conical shaped receiving cavity 16 in this embodiment may be conical or pyramidal. Also, the conical well, conical receiving cavity 16 need not be completely conical, but may be enlarged at its point to provide other structural configurations. As shown, the bottom of the cone-shaped pit is enlarged to form a lower space 19, and the side walls and bottom wall of the lower space 19 are also constructed as a concrete wall structure. The bottom of the conical accommodation chamber 16 is defined by a horizontal silo bottom wall 20, and the silo bottom wall 20 is supported at intervals on a bottom wall 22 of the conical pit through a vertical support 21.
Storehouse diapire 20 is equipped with vertical discharge gate 23, and transfer passage 24 has been seted up in the outside of storehouse lateral wall 13, and transfer passage 24 upper end is led out ground, the lower extreme extends to and is corresponding to discharge gate 23 below. The conveying channel 24 has a conveying device 25 therein. The lower end of the conveyor 25 may extend between the bottom wall 20 of the silo and the bottom wall 22 of the conical pit and correspond to the lower end of the discharge opening 23.
The conveyor 25 in this embodiment may be configured to include a conveyor belt 26 disposed along the conveyor path 24 and a conveyor cart 27 attached to the conveyor belt 26, the conveyor cart 27 being capable of receiving material from the discharge port 23 and discharging the material along the conveyor belt 26 to the ground.
Of course, as is known, the outlet 23 is only open when dispensing is required, and closed when not required. To achieve this opening or closing function, a conventional opening and closing structure 28 can be used, and will not be described in detail.
In this embodiment, optionally, a pressure reducing cone 29 is disposed at a bottom middle position of the conical accommodation cavity 16, and the pressure reducing cone 29 is a conical body with an upward pointed end. In this scheme, through setting up decompression awl 29, can hold the vertical pressure part decomposition of chamber 16 bottom to the toper with the material of storage and shift to storehouse lateral wall 13 to reduced the material and concentrated in the vertical pressure that the chamber 16 bottom was held to the toper, the pressure distribution of material is more reasonable. A pressure relief cone 29 may be provided to be supported above the bottom wall of the channel.
In this embodiment, the cartridge sidewall 13 optionally comprises an upper tapered section 30 and a lower tapered section 31 connected one above the other. The angle between the lower conical section 31 and the horizontal plane is larger than the angle between the upper conical section 30 and the horizontal plane. If the angle between the upper conical section 30 and the horizontal plane is set to 45 deg., the angle between the lower conical section 31 and the horizontal plane is set to 60 deg.. The mode of setting so is in order to improve the reasonable distribution of material. The reason is that the upper material pressure is relatively small, so the upper tapered section 30 with a smaller included angle can share the material pressure with a larger specific gravity. And relatively, the material pressure of lower part is great, and great contained angle can reduce the proportion of the material pressure that lower tapered section 31 storehouse lateral wall 13 shared to make whole storehouse lateral wall 13 about the pressure-bearing situation reasonable.
In this embodiment, the lower portion of the upper dome 12 is thicker than the upper portion, and the line of demarcation between the upper and lower portions may be the line of demarcation between the highest level line 33 and the upper dome 12 to ensure that the portion of the upper dome 12 that may be required to withstand the pressure of the material is thick enough.
The upper dome 12 in this embodiment is provided as a concrete shell dome, which is formed by applying the following method:
the coating fabric film material is fixed on the lower bin body 11, and particularly can be fixed on an annular basic beam;
inflating the membrane and keeping the constant pressure state in the membrane as construction load support;
spraying a bonding layer on the inner surface of the membrane;
spraying a polyurethane foam layer;
and (5) spraying concrete for molding after the layered steel bars are bound.
The lower bin body 11 in this embodiment is formed by the following steps: excavation of a foundation pit, initial spraying and leveling, initial spraying of a structural layer, binding of bottom layer reinforcing steel bars, middle spraying of the structural layer, binding of surface layer reinforcing steel bars and final spraying of the structural layer. Of course, other conventional casting methods may be used.
Case comparison analysis:
the following takes a repository design of the storage function of the E.C. headquarters item 475,000m3 as an example, and performs a comparative analysis of the conventional scheme and the present scheme.
In order to meet the requirements, a traditional floor-type warehouse is adopted, and a plurality of concrete warehouses need to be designed simultaneously to meet the storage requirements. According to long-term experience, a circular landing zone library of 60m diameter is cost-effective. If the ground round warehouse with the diameter of 60m and the height of 31m is used as a comparison scheme, the thickness of the cylindrical wall is 550mm, the top of the warehouse is of a grid structure, and the bottom of the warehouse is transported by 3 underground galleries. The storage capacity of a single bank is 98810m3, and 5 banks are needed to meet the storage requirement.
By adopting the scheme, one library can solve the problem. The ground structure is a concrete thin shell dome with the diameter of 124m and the rise of 40m, the thickness of the upper part is 0.15m, and the thickness of the lower part is 0.46m (taking the highest material level line as a boundary line); the underground is a funnel-shaped concrete bin (detailed in figures 1 and 2) with the same diameter (124 m), depth of 68m, thickness of 0.53m and inclination angle of 45 degrees (the bottom section is 60 degrees).
According to calculation, the total consumption of concrete, reinforcing steel bars and steel structures in the traditional scheme is 36930m3, 7668 tons and 1130 tons. The engineering dosage of the novel structural form is 16532m32582 tons of steel bars.
By adopting the scheme, the consumption of concrete engineering is about 44.8 percent of the engineering quantity of the traditional method, the consumption of steel bars is 33.7 percent of the traditional method, and 1130 tons of steel structure consumption is saved, thereby greatly reducing the engineering quantity and further reducing the investment cost.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
