Description

Anti-floating underground building
Technical Field
The present disclosure relates to an anti-floating underground building.
Background
In many areas, the anti-floating water level is very high, so the anti-floating underground building needs anti-floating measures, and usually, long anti-floating piles and anti-floating anchor rods are adopted, or earth is covered on the top plate of the anti-floating underground building and pressed, or earth is filled on the bottom plate of the anti-floating underground building or concrete is used for balancing weight, and the like. However, these measures are expensive, and some soil is soft and not suitable for uplift piles and uplift anchor rods, and a huge cost is paid when the measures are forcibly adopted. The method for earthing and balancing the weight on the top plate or the bottom plate of the anti-floating underground building can increase huge load to the garage, so that the structural concrete and the reinforcing steel bars of the anti-floating underground building are greatly increased, and finally, the manufacturing cost is high and potential safety hazards exist.

According to one embodiment of the present disclosure, a floating-resistant underground structure is provided. The anti-floating underground structure may include a floor, a sidewall, and a roof. The inner space of the underground building is formed by at least a bottom plate, a side wall and a top plate, wherein the bottom plate is positioned at the bottom of the inner space, the top plate is positioned at the top of the inner space, and the side wall forms the side wall of the inner space. Wherein the bottom plate, the side walls, the top plate, etc. may be provided in a waterproof structure, and may be made of reinforced concrete.
According to the embodiment of the disclosure, the anti-floating underground building can be used as an underground garage, an underground mall, an underground storage space and the like. The anti-floating underground building can be of a one-layer structure or a structure with more than two layers. Each layer may comprise a bottom plate, a top plate and side walls, wherein the top plate of a lower layer will constitute the bottom plate of an upper layer.
According to a further embodiment, the interior of the anti-floating underground building may be provided with support columns which may be fixed at the location of the floor and used for supporting the roof structure, each floor space may include support columns for more than two floors of the structure, and each support column for each floor space in the entire anti-floating underground building may be an integral structure from top to bottom.
In the present disclosure, the anti-floating underground structure may further include a weight body, wherein the weight body may be disposed at a lower portion of the floor, wherein when the anti-floating underground structure is of one-story structure, the weight body may be disposed at a lower portion of the floor of the one-story structure, and when the anti-floating underground structure is of two-story structure, the weight body may be disposed at a lower portion of the floor of the lowest-story structure. The weight body may extend from an outer bottom of the floor toward the foundation by a predetermined distance. Wherein the distance can be determined according to construction conditions and/or the anti-floating strength required by the counterweight body. In prior art, under the circumstances of carrying out anti-floating through the bottom plate, exert the counter weight at the upper portion of bottom plate, the pressure-bearing that will lead to the bottom plate like this is very big, causes the influence to the structure of whole building very easily to produce the potential safety hazard, moreover under this condition, because exert the counter weight on the bottom plate, will inevitably influence the floor height of building inside, will cause the sense of depression like this, under this condition, if keep the floor height that should have, will certainly lead to the fact the increase of construction cost.
The counterweight body can be fixedly connected with the bottom plate or integrally formed. The counterweight body may be designed to resist the upward buoyancy of the groundwater to prevent the anti-floating underground structure from floating upward. Wherein the weight body is arranged below the bottom plate and deep into the foundation. Compared with various anti-floating modes in the prior art, the anti-floating device is low in cost, high in practicability, good in reliability and better in anti-floating effect. For example, the method can avoid the net height requirement or the structural load problem caused by a ballast method, can avoid the problem caused by the limitation of actual conditions in the engineering pile anti-floating technology, and can also well avoid various problems caused by adopting an open drainage method in a drainage and dewatering method.
In the disclosure, the anti-floating effect can be realized by the counterweight body, and the anti-floating effect can be realized by the anti-pulling device additionally. In this case, the anti-floating of the underground building can be realized through the counterweight body and the anti-pulling device at the same time. The anti-floating device is added on the basis of the counterweight body to realize anti-floating together, so that the number of the anti-floating device can be effectively reduced to achieve the expected anti-floating effect. For example, N uplift devices may be required for an underground building to achieve a desired uplift effect, but by adding an uplift device on the basis of a counterweight body, the number N can be substantially reduced. It should be understood by those skilled in the art that in the case of using only the uplift device for anti-floating, a large number of uplift devices are required, but the construction of the uplift device is complicated and the construction period is long, and the uplift device is greatly affected by the soil quality of the foundation.
Thus, where the weight body is used in conjunction with a uplift device, the weight body may provide a first uplift force, and the uplift device may provide a second uplift force (which may be, for example, an uplift force provided by an uplift pile, and/or an uplift anchor). The sum of the first and second anti-buoyancy forces may be taken as the overall anti-buoyancy force. Wherein the design value of the anti-buoyancy formed by multiplying the sum of the integral anti-buoyancy and other anti-buoyancy by the coefficient is larger than the buoyancy value. The other anti-floating force can be, for example, anti-floating force formed by the weight of the building itself, such as the self weight of the underground building, the weight of the earth covering, and the like, and even the anti-floating force provided by the object contained in the building. The predetermined coefficient may be a coefficient preset according to actual conditions. The above-mentioned buoyancy value is an anti-buoyancy required to resist the floating of the underground structure, wherein the buoyancy value can be considered according to the circumstances of the ground water level and the like.
Thus, according to further embodiments of the present disclosure, the anti-floating underground structure may further include an anti-uplift device. The uplift device can be in the form of an uplift pile and/or an uplift anchor rod, the number of the uplift devices is one or more than two, and when more than two uplift devices exist, the uplift devices are used for providing second uplift force together. One end of the anti-pulling device can be configured to be fixedly connected with the bottom plate, wherein the joint of the anti-pulling device and the bottom plate can be subjected to waterproof treatment. One end of the anti-pulling device can be fixedly connected with the counterweight body, and can also be subjected to waterproof treatment. In particular, the uplift pile and/or the uplift anchor rod can be connected with the bottom plate to form a whole, so that the anchoring force transmission requirement and the node waterproof construction requirement are met. The other end of the uplift device may extend downward along the foundation of the underground structure by a predetermined length, wherein the predetermined length of extension is related to the uplift force that the uplift device needs to provide. In the present disclosure, the predetermined depth that the weight body extends downward toward the foundation will be less than the predetermined length that the uplift device extends downward toward the foundation.
The uplift devices can be uniformly distributed below the bottom plate, and can also be arranged in key anti-floating areas of underground buildings.
According to specific embodiments of the present disclosure, the counterweight body may be a counterweight pier, a counterweight block, a counterweight strip, and/or an integral counterweight body. Under the condition that the counterweight bodies are counterweight piers, counterweight blocks and/or counterweight strips, the counterweight bodies are distributed uniformly or non-uniformly under the bottom plate at intervals. In addition, a horizontal beam can be arranged at the lower part of the bottom plate, and the horizontal beam can be arranged at the top or near the top of the counterweight pier, the counterweight block and/or the counterweight strip so as to realize structural reinforcement. The shapes of the counterweight piers, the counterweight blocks and/or the counterweight strips are regular shapes or irregular shapes. In the case where the weight body is an integral weight body, the integral weight body is provided in all regions or in some regions of the bottom plate. The number of the integral balance weight bodies is more than one. The shape of the integral counterweight body is regular or irregular.
In addition, the counterweight body is provided with or not provided with reinforcing steel bars. And under the condition that the reinforcing steel bars are arranged in the counterweight body, the reinforcing steel bars in the counterweight body are connected with the bottom plate, and/or the support columns in the anti-floating underground building, and/or the side wall of the anti-floating underground building. In addition, the reinforcing steel bars in the counterweight body are connected with the reinforcing steel bars of the bottom plate, and/or the reinforcing steel bars of the support columns in the anti-floating underground building, and/or the reinforcing steel bars of the side wall of the anti-floating underground building. The counterweight body is concrete, cement mixing soil, broken stone cement mixing soil and/or a pressure grouting consolidation body. For example, in the present disclosure, the weight body may be cast first, and then the bottom plate may be cast on the weight body, at which time the reinforcing bars of the weight body may be connected with the reinforcing bars of the bottom plate, and if the uplift device is present, the uplift device may be disposed before or after the weight body is cast, and the bottom plate may be disposed after the weight body and the uplift device are disposed.
When the anti-floating underground building is one layer, the top plate is filled with soil or is not filled with soil, and when the anti-floating underground building is more than two layers, the top plate of the uppermost anti-floating underground building is filled with soil or is not filled with soil.
Various specific embodiments of the present disclosure will be described below with reference to the accompanying drawings. It should be noted that the common parts of the embodiments may be mutually referred to, and the above-mentioned contents may also be referred to the respective embodiments.
< example one >
Fig. 1 shows a schematic diagram according to an embodiment of the present disclosure.
As shown in fig. 1, according to one embodiment of the present disclosure, a float-resistant underground structure is provided. The anti-floating underground structure 100 may include a bottom plate 110, a sidewall 120, and a top plate 130. The interior space of the underground building is formed by at least the bottom plate 110, the side walls 120 and the top plate 130, wherein the bottom plate 110 is located at the bottom of the interior space, the top plate 120 is located at the top of the interior space, and the side walls 130 form the side walls of the interior space. Among them, the bottom plate 110, the sidewalls 120, the top plate 130, and the like may be provided in a waterproof structure, and may be made of reinforced concrete.
According to this embodiment, the anti-floating underground structure 100 may be used as an underground garage, an underground mall, an underground storage space, or the like. The anti-floating underground structure 100 may have a one-story structure or a structure having two or more stories. Each layer may include a bottom plate 110, a top plate 130, and sidewalls 120, wherein the top plate of a lower layer will constitute the bottom plate of an upper layer.
Further, the interior of the anti-floating underground structure 100 may be provided with support columns (not shown), which may be fixed at the positions of the bottom plates 110 and used for supporting the roof structure, each floor space may include support columns for more than two floors, and each support column for each floor space in the entire anti-floating underground structure may be an integral structure.
In this embodiment, the anti-floating underground building 100 may further include a weight body 140, wherein the weight body 140 may be disposed at a lower portion of the floor of a one-story structure when the anti-floating underground building 100 is the one-story structure, and the weight body 140 may be disposed at a lower portion of the floor of a lowest-story structure when the anti-floating underground building is the two-story structure.
As shown in fig. 1, the weight bodies 140 may have an irregular shape, and the number of the weight bodies and/or the extension depth of the weight bodies may be set according to the anti-buoyancy force required to be provided by the weight bodies 140.
In the present embodiment, the weight body 140 may extend a predetermined distance from the outer bottom of the base plate 110 toward the ground. Wherein the distance can be determined according to construction conditions and/or the anti-floating strength required by the counterweight body. In prior art, under the circumstances of carrying out anti-floating through the bottom plate, exert the counter weight at the upper portion of bottom plate, the pressure-bearing that will lead to the bottom plate like this is very big, causes the influence to the structure of whole building very easily to produce the potential safety hazard, moreover under this condition, because exert the counter weight on the bottom plate, will inevitably influence the floor height of building inside, will cause the sense of depression like this, under this condition, if keep the floor height that should have, will certainly lead to the fact the increase of construction cost.
The weight body 140 may be fixedly connected to the base plate 110 or integrally formed therewith. The weight body 140 may be designed to resist the buoyancy of the groundwater to prevent the anti-floating underground structure 100 from floating. Wherein the weight body 140 is disposed under the bottom plate 110 and deeply into the ground. Compared with various anti-floating modes in the prior art, the anti-floating device is low in cost, high in practicability, good in reliability and better in anti-floating effect. For example, the method can avoid the net height requirement or the structural load problem caused by a ballast method, can avoid the problem caused by the limitation of actual conditions in the engineering pile anti-floating technology, and can also well avoid various problems caused by adopting an open drainage method in a drainage and dewatering method.
In the present disclosure, while the weight body 140 achieves the anti-floating effect, the anti-floating effect may be additionally achieved using the anti-pulling device 160. In this case, the anti-floating of the underground structure can be simultaneously achieved by the weight body 140 and the anti-floating device 160. The anti-floating device 160 is added on the basis of the counterweight body 140 to realize anti-floating together, so that the number of the anti-floating devices 160 can be effectively reduced to achieve the expected anti-floating effect. For example, N uplift devices 160 may be required for an underground building to achieve a desired uplift effect, but by adding the uplift devices 160 on the basis of the weight body 140, the number N may be substantially reduced. It should be understood by those skilled in the art that in the case of using only the uplift device 160 for anti-floating, a large number of uplift devices 160 are required, but the construction of the uplift device 160 is complicated and the construction period is long, and the uplift device 160 is greatly affected by the soil quality of the foundation.
Thus, where the weight body 140 is used in conjunction with the uplift device 160, the weight body 140 may provide a first uplift resistance, while the uplift device 160 may provide a second uplift resistance (e.g., which may be an uplift resistance provided by an uplift pile, and/or an uplift anchor). The sum of the first and second anti-buoyancy forces may be taken as the overall anti-buoyancy force. Wherein the design value of the anti-buoyancy formed by multiplying the sum of the integral anti-buoyancy and other anti-buoyancy by the coefficient is larger than the buoyancy value. The other anti-floating force can be, for example, anti-floating force formed by the weight of the building itself, such as the self weight of the underground building, the weight of the earth covering, and the like, and even the anti-floating force provided by the object contained in the building. The predetermined coefficient may be a coefficient preset according to actual conditions. The above-mentioned buoyancy value is an anti-buoyancy required to resist the floating of the underground structure, wherein the buoyancy value can be considered according to the circumstances of the ground water level and the like.
Therefore, according to further embodiments of the present disclosure, the anti-floating underground structure may further include an anti-uplift device 160. The uplift devices 160 may be in the form of uplift piles and/or uplift bolts, and the number of the uplift devices 160 is one or more than two, and when there are more than two uplift devices 160, the more than two uplift devices 160 collectively provide the second uplift force. One end of the anti-pulling device 160 may be configured to be fixedly connected with the base plate 110, wherein a waterproof treatment may be performed at the connection of the two. One end of the anti-pulling device 160 may be fixedly connected to the weight body 140, or may be subjected to a waterproof treatment. In particular, the uplift pile and/or the uplift anchor rod may be integrally connected to the base plate 110 to meet both the anchoring force transfer requirement and the waterproof construction requirement of the node. The other end of the uplift device 160 may extend downward along the foundation of the underground structure by a predetermined length, wherein the predetermined length of extension is related to the anti-floating force that the uplift device 160 needs to provide.

Fig. 2 shows a schematic diagram according to an embodiment of the present disclosure.
As shown in fig. 2, according to one embodiment of the present disclosure, a float-resistant underground structure is provided. The anti-floating underground structure 200 may include a bottom plate 210, a sidewall 220, and a top plate 230. An interior space of the underground building is formed by at least the bottom plate 210, the side walls 220 and the top plate 230, wherein the bottom plate 210 is located at the bottom of the interior space, the top plate 220 is located at the top of the interior space, and the side walls 220 form the side walls of the interior space. Among them, the bottom plate 210, the sidewalls 220, the top plate 230, and the like may be provided in a waterproof structure, and may be made of reinforced concrete.
According to this embodiment, the anti-floating underground structure 200 may be used as an underground garage, an underground mall, an underground storage space, or the like. The anti-floating underground structure 200 may have a one-story structure or a structure having two or more stories. Each layer may include a bottom plate 210, a top plate 230, and sidewalls 220, wherein the top plate of a lower layer will constitute the bottom plate of an upper layer.
Further, the interior of the anti-floating underground structure 200 may be provided with support columns (not shown), which may be fixed at the positions of the bottom plates 210 and used for supporting the roof structure, each floor space may include support columns for more than two floors, and each support column for each floor space in the entire anti-floating underground structure may be an integral structure.
In this embodiment, the anti-floating underground building 200 may further include a weight body 240, wherein the weight body 240 may be disposed at a lower portion of the floor of a one-story structure when the anti-floating underground building 200 is the one-story structure, and the weight body 240 may be disposed at a lower portion of the floor of a lowest-story structure when the anti-floating underground building is the two-story structure.
As shown in fig. 2, the weight body 240 may have a regular shape, for example, the regular shape may be a square, a rectangle, a circle, a triangle, a diamond, or a special shape. The number of the weight bodies 240 and/or the extension depth of the weight bodies may also be set according to the anti-floating force that the weight bodies 240 need to provide.
In the present embodiment, the weight body 240 may extend a predetermined distance from the outer bottom of the soleplate 210 toward the foundation. Wherein the distance can be determined according to construction conditions and/or the anti-floating strength required by the counterweight body. In prior art, under the circumstances of carrying out anti-floating through the bottom plate, exert the counter weight at the upper portion of bottom plate, the pressure-bearing that will lead to the bottom plate like this is very big, causes the influence to the structure of whole building very easily to produce the potential safety hazard, moreover under this condition, because exert the counter weight on the bottom plate, will inevitably influence the floor height of building inside, will cause the sense of depression like this, under this condition, if keep the floor height that should have, will certainly lead to the fact the increase of construction cost.
The weight body 240 may be fixedly connected to the base plate 210 or may be integrally formed. The weight body 240 may be designed to resist the buoyancy of the groundwater to prevent the anti-floating underground structure 200 from floating. Wherein the weight body 240 is disposed under the floor 210 and deep into the ground. Compared with various anti-floating modes in the prior art, the anti-floating device is low in cost, high in practicability, good in reliability and better in anti-floating effect. For example, the method can avoid the net height requirement or the structural load problem caused by a ballast method, can avoid the problem caused by the limitation of actual conditions in the engineering pile anti-floating technology, and can also well avoid various problems caused by adopting an open drainage method in a drainage and dewatering method.
In the present disclosure, while the weight body 240 achieves the anti-floating effect, the anti-floating effect may be additionally achieved using the anti-pulling device 260. In this case, the anti-floating of the underground structure can be simultaneously achieved by the weight body 240 and the uplift device 260. The anti-floating device 260 is added on the basis of the counterweight body 240 to realize anti-floating together, so that the number of the anti-floating device 260 can be effectively reduced to achieve the expected anti-floating effect. For example, N number of uplift devices 260 may be required for an underground structure to achieve a desired uplift effect, but by adding the uplift devices 260 on the basis of the weight body 240, the number N may be substantially reduced. It should be understood by those skilled in the art that in the case of using only the uplift device 260 for anti-floating, a large number of uplift devices 260 are required, but the construction of the uplift device 260 is complicated and the construction period is long, and the uplift device 260 is greatly affected by the soil quality of the foundation.
Thus, where the weight body 240 is used in conjunction with the uplift device 260, the weight body 240 may provide a first uplift resistance, while the uplift device 260 may provide a second uplift resistance (e.g., which may be an uplift resistance provided by an uplift pile, and/or an uplift anchor). The sum of the first and second anti-buoyancy forces may be taken as the overall anti-buoyancy force. Wherein the design value of the anti-buoyancy formed by multiplying the sum of the integral anti-buoyancy and other anti-buoyancy by the coefficient is larger than the buoyancy value. The other anti-floating force can be, for example, anti-floating force formed by the weight of the building itself, such as the self weight of the underground building, the weight of the earth covering, and the like, and even the anti-floating force provided by the object contained in the building. The predetermined coefficient may be a coefficient preset according to actual conditions. The above-mentioned buoyancy value is an anti-buoyancy required to resist the floating of the underground structure, wherein the buoyancy value can be considered according to the circumstances of the ground water level and the like.
Therefore, according to further embodiments of the present disclosure, the anti-floating underground structure may further include an anti-uplift device 260. The uplift devices 260 may be in the form of uplift piles and/or uplift bolts, and the number of the uplift devices 260 is one or more than two, and when there are more than two uplift devices 260, the more than two uplift devices 260 provide a second uplift force together. One end of the anti-pulling device 260 may be configured to be fixedly connected with the base plate 210, wherein a waterproof treatment may be performed at the connection of the two. One end of the anti-pulling device 260 may be fixedly connected to the weight body 240, or may be subjected to a waterproof treatment. In particular, the uplift pile and/or the uplift anchor rod may be integrally connected to the base plate 210, which may not only meet the anchoring force transmission requirement, but also meet the waterproof construction requirement of the node. The other end of the uplift device 260 may extend downward along the foundation of the underground structure by a predetermined length, wherein the predetermined length of extension is related to the anti-floating force that the uplift device 260 needs to provide. In the present disclosure, the predetermined depth that the weight body 240 extends downward toward the foundation will be less than the predetermined length that the uplift device 260 extends downward toward the foundation.
The uplift devices 260 may be uniformly distributed under the bottom plate 210 or may be placed in a heavy uplift area of an underground building.
According to this embodiment, the weight body 240 may be a weight pier, a weight block, and/or a weight strip. The weight bodies 240 are uniformly or non-uniformly distributed spaced apart from each other under the soleplate 210. In addition, a horizontal beam may be provided at the lower portion of the bottom plate 210, and the horizontal beam may be provided at or near the top of the weight pier, the weight block, and/or the weight bar for structural reinforcement. The shapes of the counterweight piers, the counterweight blocks and/or the counterweight strips are regular shapes or irregular shapes.
In addition, the weight body 240 may be provided with a reinforcing bar 241 or may not be provided with a reinforcing bar. In the case where the reinforcing bars are provided in the weight body 240, the reinforcing bars in the weight body 240 are connected to a floor, and/or a support column in the anti-floating underground structure, and/or a sidewall of the anti-floating underground structure. In addition, the reinforcing bars of the weight body 240 are connected with the reinforcing bars of the bottom plate, and/or the reinforcing bars of the support columns of the anti-floating underground structure, and/or the reinforcing bars of the side walls of the anti-floating underground structure. The counterweight body 240 is concrete, cement-mixed soil, gravel cement-mixed soil, and/or a pressure grouting consolidation body. For example, in the present disclosure, the weight body 240 may be cast first, and then the chassis may be cast on the weight body 240, at which time the reinforcing bars of the weight body 240 may be connected with the reinforcing bars of the chassis, and if the uplift device 260 is present, the uplift device 260 may be disposed before or after the weight body 240 is cast, and the chassis 210 may be disposed after the weight body 240 and the uplift device 260 are disposed.
When the anti-floating underground building is one layer, the top plate is filled with soil or is not filled with soil, and when the anti-floating underground building is more than two layers, the top plate of the uppermost anti-floating underground building is filled with soil or is not filled with soil.
