Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0055] The present invention provides a semi-underground material warehouse and a material warehouse design method. Figures 1 to 7 A specific embodiment of a semi-underground material warehouse and a material warehouse design method provided by the present invention.

[0056] like Figure 1 and Figure 3As shown, an embodiment of the present invention provides a semi-underground material warehouse 100, including a warehouse body 1 that can be partially embedded underground, the warehouse body 1 having a storage cavity 11 therein, the storage cavity 11 being divided into a plurality of chambers by a partition wall 2, a plurality of partition walls 2 being provided, and the plurality of partition walls 2 being spaced apart along the length direction of the warehouse body 1, a plurality of discharge ports 12 communicating with the storage cavity 11 being spaced apart at the bottom of the warehouse body 1 along its length direction.

[0057] In the present invention, the storage chamber 11 is provided in the silo 1 that can be partially embedded in the ground. The storage chamber 11 is divided into multiple chambers by a partition wall 2. There are multiple partition walls 2, and the multiple partition walls 2 are arranged at intervals along the length direction of the silo 1. The bottom of the silo 1 is arranged at intervals along its length direction with multiple discharge ports 12 that are connected to the storage chamber 11. This application digs a foundation pit in the construction site, sets the material warehouse in the foundation pit, and makes the material warehouse partially embedded in the ground to form the semi-underground material warehouse 100. The self-weight of the soil excavated from the site is used to offset the load of the material warehouse and reduce the additional stress of the foundation, which is similar to the principle of buoyancy of a ship. Compared with the existing material warehouses set on the ground, the amount of foundation treatment engineering can be significantly reduced.

[0058] In order to prevent the material from accumulating in the corners of the storage chamber 11, in some embodiments, as Figure 2 As shown, the two side walls of the lower part of the silo 1 in the width direction are inclined downward toward the direction close to the discharge port 12. In this way, since the two side walls of the lower part of the silo 1 are inclined downward, the material slides along the inclined surface toward the discharge port 12 under the action of its own weight, which can prevent the material from accumulating in the corner of the storage cavity 11 on the one hand, and improve the efficiency of material discharge on the other hand. Specifically, the inclined surface can be formed by secondary pouring and slope leveling in the bottom plate of the material storage, and the bottom plate of the material storage is made into a flat bottom plate, or it can be directly formed by primary pouring and slope leveling of the bottom plate of the material storage.

[0059] Furthermore, in order to improve the material discharging efficiency, in some embodiments, Figure 1As shown, the semi-underground material warehouse 100 also includes a material-dispensing device 3 provided in each of the chambers, the material-dispensing device 3 includes a guide structure 31, a connecting structure 32 and a material-dispensing portion 33, the guide structure 31 includes a first guide portion 311, a second guide portion 312 and a third guide portion 313 connected end to end in sequence, the second guide portion 312 extends along the width direction of the warehouse body 1, the first guide portion 311 and the third guide portion 313 are respectively connected to the two side walls of the warehouse body 1 in the width direction, and are connected to the second guide portion 312 and the third guide portion 313 respectively. The connection of the guide portion 312 is inclined downward along the width direction of the warehouse body 1, and the connecting structure 32 includes a connecting seat 321 and a mounting portion 322. The connecting seat 321 is slidably set on the guide structure 31, and the mounting portion 322 is rotatably installed on the connecting seat 321, and the axial direction of the rotation of the mounting portion 322 extends along the height direction of the warehouse body 1. The material-pickling portion 33 is rotatably installed on the mounting portion 322, and the lower part of the chamber of the storage chamber 11 is within the effective area of ​​the material-pickling portion 33. In this way, the first guide portion 311 and the third guide portion 313 are tilted downward to avoid the insufficient length of the material-pickup portion 33, which causes the material-pickup end to be unable to contact the corner of the material storage chamber 11. At the same time, the connecting seat 321 is slidably arranged on the guiding structure 31, and the mounting portion 322 is rotatably mounted on the connecting seat 321. The material-pickup portion 33 is rotatably mounted on the mounting portion 322, so that the action range of the material-pickup portion 33 covers the entire material storage chamber 11 below the connecting structure 32, so that the material-pickup end of the material-pickup portion 33 can contact various positions at the bottom of the material storage chamber 11, avoiding material accumulation. In addition, the material-pickup portion 33 can be used to push the materials at various positions in the material storage chamber 11 to the top of the discharge port 12, thereby improving the material discharge efficiency.

[0060] Furthermore, in some embodiments, the material shifting portion 33 is retractable, so that the material shifting portion 33 is more flexible and controllable.

[0061] In some embodiments, Figure 1As shown, the semi-underground material warehouse 100 also includes a feeding device 4 arranged in the warehouse body 1, and the feeding device 4 includes a material transporting part 41 and a plurality of material distributors 42. The material transporting part 41 is arranged to move in the length direction of the warehouse body 1, and each material distributor 42 is arranged in each chamber and reciprocates in the width direction of the warehouse body 1. The moving stroke of the material transporting part 41 passes directly above the material distributor. The material is transported to the corresponding chamber according to different types by the material transporting part 41, and the material is output to the material distributor 42. The material distributor 42 transports the material to both sides of the chamber respectively, so that the material falls into the chamber, thereby achieving uniform feeding and preventing the semi-underground material warehouse 100 from tilting as a whole in the case of uneven feeding.

[0062] Furthermore, in some embodiments, both side walls of the storage chamber 11 are provided with level meters, which can detect the material heights on both sides of the storage chamber 11, and adjust the feeding position according to the height difference to achieve uniform feeding, thereby preventing the semi-underground material storage 100 from tilting as a whole due to uneven feeding.

[0063] In some embodiments, Figure 1 As shown, the semi-underground material warehouse 100 also includes a discharge device 5, which includes an electric control valve 51 and a discharge conveyor belt 52. The electric control valve 51 can cover the discharge port 12. The discharge conveyor belt 52 is arranged below the discharge port 12 and extends along the length direction of the warehouse body 1. The electric control valve 51 and the discharge conveyor belt 52 are both electrically connected to the controller. When the material needs to be discharged, the discharge conveyor belt 52 is first controlled to run, and then the electric control valve 51 is controlled to open, so that the material is discharged from the discharge port 12. This arrangement avoids the accumulation of materials between the discharge port 12 and the discharge conveyor belt 52, which on the one hand causes the discharge conveyor belt 52 to be damaged, and on the other hand causes the material to be broken, affecting the subsequent utilization.

[0064] In some embodiments, the semi-underground material warehouse 100 further includes two maintenance platforms 6, which are respectively arranged on the two outer side walls of the warehouse body 1, and the two maintenance platforms 6 extend along the length direction of the warehouse body 1 and are arranged opposite to each other in the width direction of the warehouse body 1. By arranging two maintenance platforms 6 on the outer side walls of the warehouse body 1, it is convenient for workers to inspect various components on the top of the warehouse body 1, and on the other hand, the out-of-plane stiffness of the side wall of the warehouse body 1 can be increased, and the deformation of the side wall under the action of the material pile load can be reduced, thereby strengthening the structural strength of the warehouse body 1.

[0065] Those skilled in the art will appreciate that the above structure does not constitute a limitation on the semi-underground material storage 100 , and may include more or fewer components than those described above, or a combination of certain components, or a different arrangement of components.

[0066] like Figure 4 As shown, an embodiment of the present invention provides a material warehouse design method, which is used for the semi-underground material warehouse 100 described in the above items, and the material warehouse design method includes the following steps:

[0067] Step S10: Determine the length and width of the material warehouse according to the project site process layout.

[0068] It should be noted that on the actual project site, there may be restrictions on the length and width of the material warehouse, and the engineer can use this to determine one of the length and width.

[0069] Step S20: Calculate the bottom area of ​​the material warehouse according to the length of the material warehouse and the width of the material warehouse.

[0070] It should be noted that the bottom area of ​​the material storage can be directly calculated according to the area formula.

[0071] Step S30: Obtain the designed full load weight of the material warehouse.

[0072] It should be noted that the designed full load weight is determined by engineers based on the weight of the materials to be stored and the weight of the silo itself.

[0073] Step S40: Determine the bulk density of the excavated soil according to the soil quality of the site.

[0074] It should be noted that the average density of the soil can be determined according to the soil quality of the site, and the soil bulk density can be calculated based on the average density of the soil.

[0075] Step S50: Obtain a preset underground depth of the material storage and use it as the current foundation depth.

[0076] Step S60: Obtain the designed maximum deformation of the material warehouse.

[0077] It should be noted that the designed maximum deformation is determined according to the allowable deformation of the equipment at the inlet and outlet interface of the material storage end.

[0078] Step S70: determining the final deformation of the foundation according to the bottom area of ​​the material storage, the designed full load weight, the soil bulk density and the current foundation depth.

[0079] It should be noted that, considering the rebound of the soil during the excavation of the foundation pit, the final deformation of the foundation plus the rebound deformation is the actual deformation. Since the rebound deformation is small and can be ignored, the final deformation of the foundation is used as the actual deformation for calculation.

[0080] Step S80: Compare the designed maximum deformation with the final deformation of the foundation, determine the deformation difference, and adjust the current foundation depth according to the deformation difference.

[0081] It should be noted that the deformation difference is the designed maximum deformation minus the final deformation of the foundation. If the deformation difference is less than 0, the current foundation depth is increased. If the deformation difference is greater than 0, the current foundation depth can be reduced to reduce the foundation pit depth and the amount of foundation pit excavation.

[0082] Step S90: repeating steps S70 to S80 until the deformation difference is greater than 0 and less than a preset threshold, and taking the current base depth as the minimum depth value.

[0083] It should be noted that in the actual design process, it is impossible to ensure that the deformation difference is exactly equal to 0. It is only necessary to ensure that the deformation difference is greater than 0. At the same time, in order to save costs, the foundation depth should not be too deep. A preset threshold can be set. When the deformation difference is greater than 0 and less than the preset threshold, the foundation depth at this time is taken as the minimum depth value within a reasonable range.

[0084] In this embodiment, the length and width of the material warehouse are first determined according to the process layout of the project site, the bottom area of ​​the material warehouse is calculated according to the length and width of the material warehouse, and then the designed full load weight of the material warehouse is obtained. Then, the bulk density of the excavated soil is determined according to the soil quality of the site, and then the preset underground depth of the material warehouse is obtained and used as the current foundation depth to obtain the designed maximum deformation of the material warehouse. Then, the final deformation of the foundation is determined according to the bottom area of ​​the material warehouse, the designed full load weight, the bulk density of the soil and the current foundation depth. Then, the designed maximum deformation is compared with the final deformation of the foundation to determine the deformation difference, and the current foundation depth is adjusted according to the deformation difference. Finally, the above two steps are repeated until the deformation difference is greater than 0 and less than the preset threshold, and the current foundation depth is used as the minimum depth value.

[0085] refer to Figure 5 , Figure 5 Schematic diagram of the flow chart of the second embodiment of the material warehouse design method of the present invention.

[0086] Based on the first embodiment described above, the material warehouse design method of this embodiment further includes, after step S90:

[0087] S100: Obtain the designed empty weight of the material warehouse.

[0088] S110: Obtain the groundwater depth at the project site.

[0089] S120: Obtain groundwater bulk density.

[0090] It should be noted that the groundwater depth and the groundwater density are determined based on the groundwater conditions of the actual project site.

[0091] S130: Determine a maximum depth value according to the designed empty weight, the groundwater depth, the groundwater density and the bottom area of ​​the silo.

[0092] It should be noted that the material silo is in a state of large deformation for a long time, which will affect the service life of the material silo, so it is necessary to increase the foundation depth of the material silo. However, too large a foundation depth will lead to excessive earthwork volume, which will increase the project cost, and it is necessary to consider the anti-floating problem when the material silo is completely empty. Therefore, there is a maximum depth value of the material silo under the anti-floating condition.

[0093] It should be noted that the designed empty weight is set to G1, the gravity acceleration of the construction site is g, and the groundwater depth is set to h w , the groundwater density is set to γ w , the bottom area of ​​the material storage is set as A, the buoyancy of the groundwater on the material storage is set as F, the maximum depth value is set as H, at the maximum depth, 1.05F = Gg, the calculation formula of the buoyancy is F = (Hh w )γ w A.

[0094] The maximum depth value can be calculated by substituting the designed empty weight, the groundwater depth, the groundwater density and the bottom area of ​​the silo into the above formula.

[0095] In this embodiment, the designed empty weight of the silo is first obtained, and then the groundwater depth and groundwater density of the project site are determined according to the actual groundwater conditions of the project site. Finally, the designed empty weight, the groundwater depth, the groundwater density and the bottom area of ​​the silo are substituted into the buoyancy formula to calculate the maximum depth value.

[0096] refer to Figure 6 , Figure 6 Schematic diagram of the flow chart of the third embodiment of the material warehouse design method of the present invention.

[0097] Based on the first embodiment described above, the material warehouse design method of this embodiment includes, in step S70:

[0098] Step S71: Calculate the average base stress of the silo according to the designed full load weight and the bottom area of ​​the silo.

[0099] It should be noted that the average base stress (KPa) is set to P, the designed full load weight is G2, the gravitational acceleration is g, the bottom area is A, and the calculation formula for the average base stress is P=G2g / A.

[0100] Step S72: Calculate the average additional stress of the base according to the average stress of the base, the bulk density of the soil and the current foundation depth.

[0101] It should be noted that the additional foundation stress (KPa) is set to P0, the average base stress (KPa) is set to P, and the soil bulk density (KN / m 3 ) is set to γ, the current foundation depth is set to h, and the calculation formula for the additional foundation stress is: P0=P-γh.

[0102] Substituting the obtained average stress of the base, the bulk density of the soil and the current foundation depth into the above calculation formula, the additional stress can be obtained. The additional stress refers to the soil pressure increased relative to the initial state before the excavation of the foundation pit. Since the original site is stable, it is this increased pressure that causes the subsequent compression settlement.

[0103] Step S73: Determine the total number of divided soil layers according to the current foundation depth.

[0104] Step S74: Obtain the average additional stress coefficient within the depth range from the bottom surface of the foundation to the upper and lower boundaries of each soil layer.

[0105] It should be noted that the average additional stress coefficient can be determined by engineers by referring to relevant design manuals or design specifications.

[0106] Step S75: Obtain the compression modulus of each layer of soil under the foundation bottom surface.

[0107] It should be noted that the compression modulus of each layer of soil can be obtained by referring to the geological survey report of the engineering project.

[0108] Step S76: Obtain the distance from the bottom surface of the foundation to the bottom surface of each soil layer.

[0109] It should be noted that steps S73 to S76 can be executed simultaneously without strict sequence restrictions, and can be executed in other sequences.

[0110] Step S77: Calculate the foundation deformation according to the average additional stress, the total number of soil layers, the compression modulus of each soil layer, the distance from the bottom surface of each soil layer to the bottom surface of the foundation, and the average additional stress coefficient.

[0111] It should be noted that the foundation deformation (mm) is set to S', the number of soil layers is set to n, and the compression modulus (MPa) of the i-th layer of soil under the foundation bottom is set to E si , the distance (m) from the bottom of the foundation to the bottom of the i-th soil layer is set to z i The average additional stress coefficient of the foundation soil from the bottom of the foundation to the bottom of the i-th soil layer is set as The additional foundation stress (KPa) is set as P0, and the foundation deformation calculation formula using the layered summation method is:

[0112]

[0113] The foundation deformation can be calculated by substituting the obtained additional stress, the total number of soil layers, the compression modulus of each soil layer, the distance from the bottom surface of each soil layer to the bottom surface of the foundation and the average additional stress coefficient into the above calculation formula.

[0114] Step S78: Obtaining empirical coefficients for settlement calculation.

[0115] It should be noted that the empirical coefficient for settlement calculation is determined by engineers based on regional settlement observation data and experience. When there is no regional experience, it can be determined by referring to relevant design manuals or specifications based on the equivalent value of the compression modulus within the deformation calculation depth range and the additional stress of the foundation.

[0116] Step S79: Calculate the final deformation of the foundation according to the foundation deformation and the settlement calculation empirical coefficient.

[0117] It should be noted that the final deformation of the foundation is set to S, and the empirical coefficient for settlement calculation is set to ψ s , the foundation deformation is set to S', and the final foundation deformation calculation formula is S = ψ s S'.

[0118] By substituting the obtained values ​​of the foundation deformation and the settlement calculation empirical coefficient into the above calculation formula, the final deformation of the foundation can be calculated.

[0119] refer to Figure 7 , Figure 7 Schematic diagram of the flow chart of the fourth embodiment of the material warehouse design method of the present invention.

[0120] Based on the first embodiment described above, the material warehouse design method of this embodiment further includes, after step S90:

[0121] Step S100: Obtain the stock of materials to be stored.

[0122] It should be noted that the average density of the material can be obtained by conducting experiments based on the type of material, and the amount of material to be stored can be estimated based on the weight of the material when the warehouse is fully loaded and the average density of the material.

[0123] Step S110: Obtain the natural angle of repose of the material to be stored.

[0124] It should be noted that the natural repose angle can be obtained through experimental calculation based on values ​​such as the particle size of the material.

[0125] Step S120: Calculating the material storage height according to the material storage amount and the natural repose angle.

[0126] It should be noted that the material storage capacity is the material volume. When the material warehouse is fully loaded, the shape of the material is approximately a triangular prism. If the material volume and the natural angle of repose are known, the storage height can be calculated by the volume formula.

[0127] Step S130: calculating the distance between adjacent discharge ports 12 according to the material storage height and the natural repose angle.

[0128] It should be noted that the storage height is set to H l , the natural repose angle is set to θ, the spacing is set to L, and the calculation formula is L = 2H l cotθ.

[0129] In this embodiment, experiments are first conducted based on the type of material to obtain the average density of the material, and the material storage capacity to be stored can be estimated based on the material weight when the material bin is fully loaded and the material average density, and then the natural angle of repose of the material to be stored is obtained, and then the storage height is calculated based on the material storage capacity and the natural angle of repose, and finally the distance between adjacent discharge ports is calculated based on the storage height and the natural angle of repose.
