Description

Underground building and underground garage

Technical Field

The disclosed embodiment relates to an underground building and an underground garage.

Background

The underground structure is affected by the buoyancy of the underground water, so that additional anti-buoyancy force needs to be provided to resist the change of the underground water in the design process of the underground structure.

The anti-floating method commonly adopted at present is a counterweight method, an anti-floating pile or an anti-floating anchor rod. In the counter-weight method, the self weight of the underground building is increased to resist the buoyancy of underground water, for example, earth can be backfilled on the upper roof of the underground building by backfilling on the bottom plate, but the internal space of the building is greatly sacrificed in the case of the bottom plate earth covering or the bearing pressure of the underground building is increased in the case of the top earth covering. The anti-floating pile mainly utilizes the friction between the side surface of the anti-floating pile and the foundation soil body to resist the buoyancy of underground water, the effect of the anti-floating pile has great relation with the pile length, the pile diameter, the pile shape and the surrounding geological conditions, and because the manufacturing cost of the anti-floating pile is high, the anti-floating pile is generally used in places with larger anti-floating area, such as columns, walls and the like, and is greatly influenced by environmental conditions and construction conditions. The anti-floating anchor rod is an anchoring body formed by the anchor rod and mortar, so that the binding force of the anchoring body and a rock-soil layer is ensured, and the anti-floating capacity of an underground building can be improved.

Moreover, the water level of the underground or the ground surface of some areas is very high; the underground or surface water level of some regions varies greatly along with seasons or weather; the water level fall of the rich water period and the dry water period of some areas is large; for example, the rich water period is short, and the water level is low most of the time. Therefore, the ground water level situation of each region is very complicated, and the ground water level has a great influence on underground buildings. Even a brief rise in the ground water level can pose a huge threat to the buoyancy of the underground building, thereby destroying the building structure. Therefore, the anti-floating measures of underground buildings are very important. In the existing modes, automatic adjustment cannot be carried out according to the actual condition of the water level. In addition, water resources are precious, and in the traditional underground building structure, even if the underground water level is high, the underground water level cannot be utilized, so that the precious water resources are not reserved completely.

According to one embodiment of the present disclosure, an underground structure is provided. The underground structure may include a floor, side walls, and a roof. The inner space of the underground building is formed by at least a bottom plate, side walls 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 walls form the side walls of the inner space. Wherein, bottom plate, side wall and roof etc. all can set up waterproof construction to can be made by reinforced concrete. According to the embodiment of the present disclosure, the underground building can be used as an underground garage, an underground mall, an underground storage space, an underground office space, and the like. And the underground building can be a one-layer structure or a structure with more than two layers. Each floor may include a floor, a roof and side walls, wherein the roof of the underlying underground structure will constitute the floor of the overlying underground structure. In addition, support columns may be provided in the anti-floating underground space to support the associated structure, for example, support columns may be provided between the upper deck and the lower deck to support the upper deck, etc., and in addition, in the presence of intermediate floors, intermediate floors may also be supported by support columns, for example, sandwich panels of a compound garage (as described herein below). When the underground building is one floor, the top plate is filled with soil or is not filled with soil, and when the underground building is more than two floors, the top plate of the uppermost underground building is filled with soil or is not filled with soil.

According to embodiments of the present disclosure, a water storage anti-floating facility and a counter weight anti-floating facility may be included. The water storage anti-floating facility is arranged above the bottom plate, near the bottom plate or outside the underground building, and can receive underground water from the outside of the underground building to adjust the water level of the underground water, so that the buoyancy formed by the underground water to the building is controlled. For example, when the groundwater rises, the groundwater outside the building can be made to flow out, so that the rising of the water level of the groundwater is restrained, and accordingly, the buoyancy generated by the groundwater is reduced. The counterweight anti-floating facility is arranged at the lower part of the bottom plate, and counterweight anti-floating force is provided by a counterweight body fixedly connected with or integrally formed with the bottom plate. That is, in the present disclosure, in addition to other anti-buoyancy force by the weight of the building itself, etc. (e.g., anti-buoyancy force by the self weight of the underground building, the weight of the earth covering, etc.), in the present disclosure, additional anti-buoyancy force is provided by reducing the buoyancy force by the groundwater by the water storage anti-floating facility and the counter weight anti-floating facility.

The water storage anti-floating facility in the present disclosure can receive and contain groundwater according to the water level condition of groundwater outside the underground building so as to automatically adjust the buoyancy formed by the groundwater.

The water storage anti-floating facility may include a water storage unit and an intake pipe. The water storage unit may be disposed on or near the floor, or may be disposed outside the underground structure (e.g., the water storage unit may be disposed on an upper portion of a ceiling (e.g., an uppermost ceiling) of the underground structure). In the present disclosure, in addition to suppressing water buoyancy by taking out underground water outside the building, anti-buoyancy may be provided to the underground building by the weight of water stored in the storage unit. The water storage unit serves to store groundwater collected from the outside of the underground building, and the stored groundwater may also be further used. The water storage unit may be in the form of a water storage tank disposed between the base plate and the ground of the underground building. The water storage unit can also be in the form of a water storage cabin, the lower part of the water storage cabin is a bottom plate, and the upper part of the water storage cabin is the ground inside an underground building, namely, an interlayer space formed by the bottom plate and the ground can be used as the water storage cabin.

Groundwater may be introduced into the water storage unit through the intake pipe. The inlet pipe may include an inlet port and an overflow port. The number of the water storage units is at least one, each water storage unit is provided with a corresponding water inlet pipeline, and the number of the water inlet pipelines corresponding to each water storage unit is one or more than two. The water inlet may be provided on the outside of the floor and/or the outside of the side walls. The water inlet may be designed to allow groundwater outside the underground building to flow into the water storage unit through the intake pipe via the water inlet. The number of the water inlets can be one or more, that is to say, the number of the water inlets can be more than one for each water storage unit. In addition, the filter device can be further included and is arranged at or near the water inlet so as to filter the underground water entering the water inlet pipeline. Wherein the filter means may be square, rectangular, circular or any other suitable shape.

The overflow is provided inside or outside the underground building and is designed to have a predetermined height equal to or less than a designed anti-floating water level critical value of the underground building so as to be effectively controlled when buoyancy generated by groundwater, which is dischargeable into the water storage unit through the intake pipe and the overflow, approaches a certain value. In order to effectively suppress the buoyancy generated by the groundwater, the intake pipe and the overflow vent are designed such that the buoyancy generated by the groundwater of a predetermined height (e.g., a peak height) cannot exceed the anti-buoyancy design value of the underground structure. Wherein, a control valve can be arranged at the position of the overflow port, and the control valve can be automatically opened or manually opened. For example, in case of automatic opening, if it is detected that the water level of the underground structure reaches or approaches a certain value (for example, a design anti-floating water level critical value), the control valve may be automatically opened to allow the groundwater to flow into the water storage unit, and in addition, in the present disclosure, the groundwater may be discharged to the outside of the underground structure through the water inlet, the water inlet pipe, and the overflow port.

The water inlet pipeline also comprises a water intake port, the height of the water intake port is lower than the preset height of the overflow port, and the underground water can be taken out from the outside of the underground building through the water intake port. The height of the water intake port may be set to be slightly higher than the height of the top of the water storage unit. The water intake may also be provided with a control valve so that the control valve can be opened when the user needs to take water from outside the underground building.

Still further, a transparent pipe may be further included, the transparent pipe being in fluid communication with the water inlet pipe to make the water levels of the two coincide, so that the water level of the groundwater is determined by observing the water level of the transparent pipe, and a corresponding control may be performed accordingly. The transparent tube can be marked with scales.

The periphery of the bottom plate and/or the lateral wall of underground building is provided with the district of permeating water, and the district of permeating water is set up by local, intercommunication setting and/or comprehensive setting, and wherein, local setting means sets up the district of permeating water in above-mentioned outlying part, and comprehensive setting means sets up the district of permeating water in whole periphery, and the intercommunication setting means can set up a plurality of districts of permeating water and these district of permeating water are linked together. The permeable region may be in the form of a permeable layer, a permeable gutter and/or a permeable tube, or may be in any other suitable form. In the disclosed embodiment, the filter device and the water inlet of the water inlet pipe may be disposed in the water permeable region.

Furthermore, the water storage device can further comprise water taking pipelines for discharging water in the water storage units, and the number of the water taking pipelines corresponding to each water storage unit is more than one. The water intake line includes an inlet end and an outlet end. The inlet port is disposed inside the water storage unit, for example, the inlet port may be disposed near the bottom of the water storage unit. A water pump may be provided at the inlet end. The outlet port may be located outside the water storage unit and/or outside the underground structure, for example the outlet port may be located inside the underground structure or outside the underground structure, for example through the overburden, extending above the external ground.

Through above-mentioned anti facility that floats of water storage, can give the building with wisdom, dissolve the harm that the water buoyancy of rich water period brought and store water, can change the harm into the treasured and utilize like this, can accomplish automatic digestion water buoyancy, automatic water storage function, the water of storing becomes resistance anti-floating again, more importantly has sponge city and wisdom city function to reduce the quantity of resistance to plucking the device by a wide margin, can shorten construction period effectively, reduce construction cost etc..

The counterweight anti-floating facility can be arranged at the lower part of the bottom plate, and the counterweight anti-floating force is provided by a counterweight body fixedly connected with or integrally formed with the bottom plate. For example, in the case of a one-story underground building, the counter weight anti-floating facility may be provided below the floor, and in the case of a two-story or more underground building, the counter weight anti-floating facility may be provided below the lowermost floor. In particular, the counter weight anti-floating facility may be in the form of a counter weight body.

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 the prior art, under the condition that the counter weight is applied to the upper part of the bottom plate to resist floating, the pressure bearing of the bottom plate is large, the structure of the whole building is easily affected, and therefore potential safety hazards are generated. In addition, the application of the counterweight on the bottom plate inevitably affects the floor height inside the building, which causes a sense of depression, and if the ideal floor height is maintained, the building cost is inevitably increased.

The counterweight body can be fixedly connected with the bottom plate or integrally formed. The counterweight body may provide a second type of anti-buoyancy to resist uplift of the groundwater to prevent uplift of the subterranean structure. Wherein the counterweight body is arranged below the bottom plate and extends 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 other problems in the prior art.

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. In case that the reinforcing bars are provided in the weight body, the reinforcing bars in the weight body are connected with the floor, and/or the support pillars in the underground structure, and/or the side walls of the underground structure. 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 underground building, and/or the reinforcing steel bars of the side walls of the underground building. The counterweight body is concrete, cement mixing soil, broken stone cement mixing soil and/or a pressure grouting consolidation body.

Further, on the basis of the water storage anti-floating facility and the counterweight anti-floating facility, an anti-pulling device in the prior art can be combined to provide anti-pulling anti-floating force. Because the water storage anti-floating facility and the counterweight anti-floating facility can have obvious effect on the anti-floating of the underground building. In the case of additionally adding the uplift device, the additional guarantee can be provided for the anti-floating of the underground building. And the anti-pulling and anti-floating force is provided by matching with the water storage anti-floating facility and the counterweight anti-floating facility, so that the number of anti-pulling devices can be effectively reduced, and the expected anti-floating effect is achieved. For example, N uplift devices may be required for one underground building to achieve a desired uplift effect, but by adding the uplift devices on the basis of water storage and counter-weight uplift facilities, the number N can be greatly 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, according to further embodiments of the present disclosure, the uplift devices may be in the form of uplift piles and/or uplift bolts, and the number of the uplift devices is one or more than two, when there are more than two uplift devices, the more than two uplift devices to collectively provide uplift buoyancy. 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.

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.

The underground building 10 may include: a bottom plate 110, a side wall 120, a water storage 130 and an inlet pipe 140. In addition, the underground structure may also include a top plate 150, so that the bottom plate 110, the side walls 120, and the top plate 150 may form the underground structure. The underground structure is a one-story type underground structure or an at least two-story type underground structure. In the one-story type underground building, the bottom plate 110 of the below-described storage 130 may be the bottom plate 110 of the underground building, and in the two-story or more type underground building, the bottom plate 110 of the below-described storage 130 may be the bottom plate 110 of the lowermost underground building. Further, a soil cover layer 160 may be provided on the top plate 150 of the underground building, for example, a soil cover layer 160 may be provided on the uppermost top plate 150 of the underground building in the form of two or more stories. Of course, it will be understood by those skilled in the art that the covering may be absent, or a building or the like may be provided. In addition, support columns may be provided in the underground building to support a roof or the like, for example, the support columns may be provided between the roof and the floor, and an intermediate floor may be supported by the support columns.

The bottom plate 110 may constitute the bottom of the underground structure, and the side walls 120 may constitute the side walls of the underground structure, wherein the bottom plate 110 and the side walls 120 may be made waterproof to prevent groundwater outside the underground structure from penetrating into the underground structure.

The water storage anti-floating facility may comprise a water storage tank and an inlet pipe. The storage 130 may be provided on or near the floor 110 or may be provided outside the underground structure, and the storage 130 is used to store groundwater collected from outside the underground structure, and the groundwater may be further used. Wherein the reservoir 130 may be formed as an open-topped vessel or the top may be closed. The reservoir 130 is disposed on the floor of the base plate, or both above and below the floor of the base plate.

The inlet pipe 140 may include an inlet port 141 and an overflow port 142. The number of the water storage 130 is at least one. In the case of a plurality of tanks, a plurality of tanks may be distributed in the space of the underground building. Each water storage 130 is provided with a corresponding water inlet pipe 140, and the number of the water inlet pipes 140 corresponding to each water storage 130 is one or more than two. The water inlet 141 may be disposed outside the bottom plate 110 and/or outside the sidewall 120.

The water inlet 141 may be designed to allow groundwater outside the underground building to flow into the water reservoir 130 through the inlet pipe 140 via the water inlet 141.

A filtering device 143 may be further included, and the filtering device 143 is disposed at or near the water inlet 141 to filter the groundwater introduced into the intake pipe 140. Wherein the filter 143 may be square, rectangular, circular or any other suitable shape.

The overflow 142 is provided inside or outside the underground building and is designed to have a predetermined height, which is equal to or less than a design anti-floating water level critical value of the underground building, so that it can be effectively controlled when buoyancy generated by groundwater, which can be discharged into the water storage tank 130 through the intake pipe 140 and the overflow, approaches an anti-floating design value of the underground building. In order to effectively control the buoyancy generated by the groundwater, the intake pipe 140 is designed such that the buoyancy generated by the groundwater at the peak height cannot exceed the anti-buoyancy design value of the underground building. Wherein, a control valve can be arranged at the position of the overflow port, and the control valve can be automatically opened or manually opened.

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 300 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 300 needs to provide. In the present disclosure, the predetermined depth that the weight body 210 extends downward toward the foundation will be less than the predetermined length that the uplift device 300 extends downward toward the foundation. The uplift devices 300 may be uniformly distributed under the bottom plate 110 or may be disposed in a heavy uplift region of an underground building.

Fig. 13 shows a schematic diagram according to another embodiment of the present disclosure. The embodiment of fig. 13 differs from the embodiment of fig. 9 in that in the embodiment of fig. 9 the weight bodies are weight piers, weights, and/or weight bars, whereas in the embodiment of fig. 13 the weight bodies may be shaped as unitary weight bodies. It should be noted that the description of the embodiment that is the same as the embodiment of fig. 9 is not repeated in this embodiment. In the embodiment of fig. 13, the weight 210 may be a solid weight. The integral weight body can be irregular in shape, and the number of the weight bodies and/or the extension depth of the weight bodies can be set according to the anti-buoyancy force required to be provided by the weight bodies.

Fig. 14 shows a schematic diagram according to another embodiment of the present disclosure. The embodiment of fig. 14 is different from the embodiment of fig. 13 in that while the water storage anti-floating facility and the counterweight anti-floating facility realize anti-floating, the anti-floating device 300 can be additionally adopted to realize anti-floating at the same time. It should be noted that the description of the embodiment that is the same as the embodiment of fig. 13 is not repeated in this embodiment. In the embodiment of fig. 14, the anti-floating of the underground building can be realized by the water storage anti-floating facility, the counterweight anti-floating facility and the uplift device 300 at the same time. The anti-floating device 300 is added on the basis of the water storage anti-floating facility and the counterweight anti-floating facility to realize the anti-floating together, so that the number of the anti-floating devices 300 can be effectively reduced to achieve the expected anti-floating effect. For example, N uplift devices 300 may be required for one underground building to achieve a desired uplift effect, but the number N may be greatly reduced by adding the uplift devices 300 on the basis of water storage and counter-floating facilities. It should be understood by those skilled in the art that in the case of using only the uplift device 300 for the anti-floating, a large number of uplift devices 300 are required, but the construction of the uplift devices 300 is complicated and the construction period is long, and the uplift devices 300 are greatly affected by the soil property of the foundation. According to further embodiments of the present disclosure, the uplift devices 300 may be in the form of uplift piles and/or uplift anchors, and the number of the uplift devices 300 is one or more than two, and in case that there are more than two uplift devices 300, the more than two uplift devices 300 collectively provide uplift buoyancy. One end of the anti-pulling device 300 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 300 may be fixedly connected to the weight body 210, 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 300 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 300 needs to provide. In the present disclosure, the predetermined depth that the weight body 210 extends downward toward the foundation will be less than the predetermined length that the uplift device 300 extends downward toward the foundation. The uplift devices 300 may be uniformly distributed under the bottom plate 110 or may be disposed in a heavy uplift region of an underground building.

Fig. 15 shows a schematic diagram according to another embodiment of the present disclosure. The embodiment of fig. 15 differs from the embodiment of fig. 13 in that the shape of the integral weight body is irregular in the embodiment of fig. 13, whereas the shape of the integral weight body is regular in the embodiment of fig. 15. It should be noted that the description of the embodiment same as that of fig. 9 and 13 is not repeated in this embodiment. In the embodiment of fig. 15, the weight 210 may be an integral weight, wherein the integral weight may be a regular shape, for example, the regular shape may be a square, a rectangle, a circle, a triangle, a diamond, or a special shape, and the number of weights and/or the extension depth of the weights may be set according to the anti-buoyancy force required to be provided by the weights.

Fig. 16 shows a schematic diagram according to another embodiment of the present disclosure.
