Description

Technical Field

[0001] This application relates to the technical field of building construction, and particularly relates to a bottom plate structure of a sluice chamber for urban underground space. Background Art

[0002] The bottom plate structure of urban underground space is an important part of underground buildings, equivalent to the ground on the bottommost layer of the building, usually made of materials such as reinforced concrete. It bears the load from the upper structure and transfers it to the foundation. Common underground spaces generally include basements, underground parking lots, sluice chambers, etc.

[0003] Since the weight of the underground space is lighter than the original soil mass in this area and is in a compensatory state for a long time, the anti - floating problem of the bottom plate needs to be considered. Otherwise, it may cause the bottom plate to bulge and crack. Therefore, during the construction process, most of the time, anti - floating anchor rods are installed at the bottom of the bottom plate to improve the anti - floating ability of the bottom plate and avoid potential safety hazards caused by the cracking of the bottom plate.

[0004] However, during the actual use process, when installing anti - floating anchor rods to support the bottom plate, it is mostly necessary to drill anchor holes in the soil layer at the bottom of the bottom plate, then place the anchor rods in the holes, and then pour cement mortar into the anchor holes. However, during the process of pouring the mortar, the anchor rods cannot be well stabilized, making the anchor rods prone to tilt, thereby reducing the pull - out resistance of the anchor rods and increasing the risk of cracking of the bottom plate. For this reason, this application provides a bottom plate structure of a sluice chamber for urban underground space. Utility Model Content

[0005] The purpose of this application is to solve the problem that during the process of pouring mortar, the anchor rods cannot be well stabilized, making the anchor rods prone to tilt, thereby reducing the pull - out resistance of the anchor rods and increasing the risk of cracking of the bottom plate. This application provides a bottom plate structure of a sluice chamber for urban underground space.

[0006] This application specifically adopts the following technical solutions to achieve the above - mentioned purpose:

[0007] A bottom plate structure of a sluice chamber for urban underground space includes foundation soil. The top of the foundation soil is fixedly connected with a bottom plate body. The top of the bottom plate body is symmetrically and fixedly connected with a plurality of support columns. The top of the plurality of support columns is fixedly connected with a top surface. Drainage ditches are opened on all four sides of the bottom plate body. A sump is arranged in the middle of the drainage ditches. A drainage component is installed inside the sump. A plurality of foundation pile holes are opened inside the foundation soil. Anchor rods are installed inside the plurality of foundation pile holes. A stabilizing member is installed inside the anchor rods.

[0008] By adopting the above technical solution, the anchor rod can be stabilized inside the pile foundation hole by manipulating the stabilizing member inside the anchor rod. Subsequently, cement mortar is poured into the pile foundation hole. The support of the stabilizing member for the anchor rod can effectively improve the overall anti-floating effect and stability of the anchor rod, thereby improving the safety of the bottom plate body. The drainage component inside the catch basin discharges the groundwater to the outside, thereby reducing the buoyancy effect of the groundwater on the bottom plate body, reducing the possibility of cracking of the bottom plate body, and greatly improving the service life of the bottom plate body.

[0009] Further, a plurality of first drain pipes are uniformly and fixedly connected to the top of the drainage ditch. The other ends of the plurality of first drain pipes are connected to the underground soil. The bottom of the drainage ditch is fixedly connected with a second drain pipe, and the other end of the second drain pipe is located inside the foundation soil.

[0010] By adopting the above technical solution, through the first drain pipes at the top and the second drain pipe at the bottom of the drainage ditch, the groundwater can enter the drainage ditch in an organized manner, and the groundwater level can be controlled within a predetermined range.

[0011] Further, the drainage component includes two drain pipes symmetrically and fixedly connected inside the catch basin. Water pumps are fixedly connected to both of the two drain pipes, and the top ends of the drain pipes penetrate through the top of the top surface.

[0012] By adopting the above technical solution, through the operation of the water pumps, the groundwater accumulated inside the catch basin is pumped to the outside through the drain pipes, thereby reducing the buoyancy effect of the groundwater on the bottom plate body, reducing the possibility of cracking of the bottom plate body, and greatly improving the service life of the bottom plate body.

[0013] Further, a fixing plate is fixedly connected to one side inside the catch basin. A guide rod is fixedly connected to the bottom of the fixing plate. A floating ball is slidably connected to the guide rod. A pressure sensor is fixedly connected to the bottom of the fixing plate, and the pressure sensor is electrically connected to an external controller.

[0014] By adopting the above technical solution, as the water level rises, it will drive the floating ball to contact the pressure sensor. At this time, after the pressure sensor receives the pressure, it will start the operation of the water pump through the external controller.

[0015] Further, the stabilizing member includes a bidirectional threaded rod rotatably connected inside the anchor rod. A knob is fixedly connected to the top of the bidirectional threaded rod. Two threaded sleeves are symmetrically threadedly connected to the bidirectional threaded rod. A plurality of groups of support plates are uniformly fixedly connected to the two threaded sleeves. One end of each of the two support plates is hinged to a hinge rod, and the end of the hinge rod away from the support plate is hinged to a connecting column.

[0016] By adopting the above technical solution, the rotation of the bidirectional threaded rod will cause the two threaded sleeves to gradually approach each other. When the two threaded sleeves gradually approach each other, they will push multiple hinged rods to rotate, thereby pushing out multiple fitting plates from the inside of the guiding groove.

[0017] Furthermore, a plurality of guiding grooves are formed on the anchor rod, and one end of the connecting column is fixedly connected with a fitting plate, and the shape and size of the fitting plate are the same as those of the guiding groove.

[0018] By adopting the above technical solution, through the cooperation of multiple fitting plates, the overall anti-floating effect and stability of the anchor rod can be effectively improved, thereby improving the safety of the bottom plate body.

[0019] Furthermore, a reinforcing nail is fixedly connected to one end of the fitting plate.

[0020] By adopting the above technical solution, when the outer wall of the fitting plate is in contact with the inner wall of the pile foundation hole, the reinforcing nail will be inserted into the internal foundation soil.

[0021] Furthermore, a waterproof curtain is fixedly connected to the outer wall of the bottom plate body.

[0022] By adopting the above technical solution, the waterproof curtain can block groundwater and reduce the influence of groundwater on the bottom plate body.

[0023] In summary, the present application includes at least one of the following beneficial effects:

[0024] 1. In the present application, a pile foundation hole, an anchor rod and a stabilizing member are provided. By controlling the stabilizing member inside the anchor rod, the anchor rod can be stabilized inside the pile foundation hole. Subsequently, cement mortar is poured into the pile foundation hole. The support of the stabilizing member to the anchor rod can effectively improve the overall anti-floating effect and stability of the anchor rod, thereby improving the safety of the bottom plate body.

[0025] 2. In the present application, a drainage ditch and a drainage component are provided. Through the first drain pipe at the top and the second drain pipe at the bottom of the drainage ditch, groundwater can enter the inside of the drainage ditch in an organized manner. The drainage component inside the catch basin discharges the groundwater to the outside, thereby reducing the buoyancy effect of groundwater on the bottom plate body and reducing the possibility of cracking of the bottom plate body, greatly improving the service life of the bottom plate body.

Detailed implementation manners

[0032] The following will Figures 1-4 further describe this application in detail.

[0033] The embodiment of this application discloses a bottom plate structure of a lock chamber for urban underground space.

[0034] Referring to Figure 1 and Figure 2 , a bottom plate structure of a lock chamber for urban underground space includes foundation soil 1, a bottom plate body 2 is fixedly connected to the top of the foundation soil 1, a plurality of support columns 3 are symmetrically and fixedly connected to the top of the bottom plate body 2, a top surface 4 is fixedly connected to the top of the plurality of support columns 3, drainage ditches 5 are opened on the four sides of the bottom plate body 2, a sump well 6 is arranged in the middle of the drainage ditch 5, a drainage assembly 7 is installed inside the sump well 6, a plurality of foundation pile holes 10 are opened inside the foundation soil 1, anchor rods 11 are installed inside the plurality of foundation pile holes 10, a stabilizing member is installed inside the anchor rod 11, a plurality of first drain pipes 8 are evenly and fixedly connected to the top of the drainage ditch 5, the other ends of the plurality of first drain pipes 8 are connected to the underground soil, a second drain pipe 9 is fixedly connected to the bottom of the drainage ditch 5, and the other end of the second drain pipe 9 is located inside the foundation soil 1, and waterproof curtains 12 are fixedly connected to the outer walls of the bottom plate body 2.

[0035] During construction, first, a plurality of foundation pile holes 10 are formed inside the foundation soil 1. Subsequently, a plurality of anchor rods 11 are placed inside the foundation pile holes 10. At this time, by controlling the stabilizer inside the anchor rod 11, the anchor rod 11 can be stabilized inside the foundation pile holes 10. Then, cement mortar is poured into the foundation pile holes 10. The support of the stabilizer for the anchor rod 11 can effectively improve the overall anti-floating effect and stability of the anchor rod 11, thereby improving the safety of the bottom plate body 2. After the installation of the anchor rod 11 is completed, the bottom plate body 2, the support columns 3, and the top surface 4 can be laid in sequence to complete the construction of the entire underground space. In addition, during daily use, since the foundation soil 1 usually contains abundant groundwater, it is easy to form a "basin pool effect" inside the foundation soil 1, resulting in inconsistent deformation between the bottom plate body 2 and the top surface 4, which may cause large-area cracking of the bottom plate body 2. Therefore, drainage ditches 5 are respectively provided around the bottom plate body 2. Through the drain pipe 8 at the top and the drain pipe 9 at the bottom of the drainage ditch 5, the groundwater can enter the inside of the drainage ditch 5 in an organized manner, and the groundwater level can be controlled within a predetermined range. Subsequently, the groundwater entering the inside of the drainage ditch 5 will be guided into the inside of the sump 6, and the groundwater will be discharged to the outside through the drainage component 7 inside the sump 6, thereby reducing the buoyancy effect of the groundwater on the bottom plate body 2 and reducing the possibility of cracking of the bottom plate body 2, greatly improving the service life of the bottom plate body 2.

[0036] Refer to Figure 1 and Figure 3 As shown in FIGS. 7 and 8, the drainage component 7 includes two drain pipes 71 symmetrically and fixedly connected inside the sump 6. Water pumps 72 are fixedly connected to both of the two drain pipes 71. The top ends of the drain pipes 71 penetrate through the top of the top surface 4. One side inside the sump 6 is fixedly connected with a fixing plate 73. A guide rod 74 is fixedly connected to the bottom of the fixing plate 73. A floating ball 75 is slidably connected to the guide rod 74. A pressure sensor 76 is fixedly connected to the bottom of the fixing plate 73. The pressure sensor 76 is electrically connected to an external controller.

[0037] During use, when the groundwater enters the inside of the sump 6 through the drainage ditch 5, it will gradually accumulate in the sump 6. At this time, according to the buoyancy of the groundwater, the floating ball 75 will rise inside the guide rod 74. As the water level rises, the floating ball 75 will be driven to contact the pressure sensor 76. At this time, after the pressure sensor 76 receives the pressure, it will start the water pump 72 to operate through the external controller to pump the groundwater accumulated inside the sump 6 to the outside through the drain pipe 71, thereby reducing the buoyancy effect of the groundwater on the bottom plate body 2 and reducing the possibility of cracking of the bottom plate body 2, greatly improving the service life of the bottom plate body 2.

[0038] Refer to Figure 2 and Figure 4, the stabilizing member includes a bidirectional threaded rod 111 rotatably connected inside the anchor rod 11. A knob 112 is fixedly connected to the top of the bidirectional threaded rod 111. Two threaded sleeves 113 are symmetrically and threadedly connected to the bidirectional threaded rod 111. Multiple groups of support plates 114 are fixedly connected to the two threaded sleeves 113 evenly. Wherein, hinge rods 115 are hinged on the opposite surfaces of every two support plates 114. One end of the hinge rod 115 away from the support plate 114 is hinged with a connecting column 116. Multiple guiding grooves 117 are formed in the anchor rod 11. One end of the connecting column 116 is fixedly connected with a fitting plate 118. The shape and size of the fitting plate 118 are the same as those of the guiding groove 117. A reinforcing nail 119 is fixedly connected to one end of the fitting plate 118.

[0039] When in use, first rotate the knob 112 to drive the bidirectional threaded rod 111 to rotate. Due to the rotation of the bidirectional threaded rod 111, the two threaded sleeves 113 will gradually approach each other. When the two threaded sleeves 113 gradually approach each other, it will push multiple hinge rods 115 to rotate, thereby pushing multiple fitting plates 118 out of the guiding groove 117 until the outer wall of the fitting plate 118 is in close contact with the inner wall of the pile foundation hole 10. When the outer wall of the fitting plate 118 is in contact with the inner wall of the pile foundation hole 10, the reinforcing nail 119 will be inserted into the foundation soil 1. Through the cooperation of multiple fitting plates 118, the overall anti-floating effect and stability of the anchor rod 11 can be effectively improved, thereby improving the safety of the bottom plate body 2.

[0040] The implementation principle of the bottom plate structure of a lock chamber for urban underground space in this embodiment is as follows: First, multiple pile foundation holes 10 are formed in the foundation soil 1, and then multiple anchor rods 11 are placed inside the pile foundation holes 10. At this time, rotate the knob 112 to drive the bidirectional threaded rod 111 to rotate. Due to the rotation of the bidirectional threaded rod 111, the two threaded sleeves 113 will gradually approach each other. When the two threaded sleeves 113 gradually approach each other, it will push multiple hinge rods 115 to rotate, thereby pushing multiple fitting plates 118 out of the guiding groove 117 until the outer wall of the fitting plate 118 is in close contact with the inner wall of the pile foundation hole 10. When the outer wall of the fitting plate 118 is in contact with the inner wall of the pile foundation hole 10, the reinforcing nail 119 will be inserted into the foundation soil 1. Through the cooperation of multiple fitting plates 118, the overall anti-floating effect and stability of the anchor rod 11 can be effectively improved, thereby improving the safety of the bottom plate body 2. After the anchor rods 11 are installed, the bottom plate body 2, the support columns 3 and the top surface 4 can be laid in sequence to complete the construction of the entire underground space;

[0041] In addition, during daily use, since the foundation soil 1 usually contains abundant groundwater inside, it is easy to form a "basin pond effect" inside the foundation soil 1, resulting in inconsistent deformation between the bottom plate body 2 and the top surface 4, which may cause large-area cracking of the bottom plate body 2. Therefore, drainage ditches 5 are respectively provided around the bottom plate body 2. Through the drain pipe 8 at the top and the drain pipe 9 at the bottom of the drainage ditch 5, the groundwater can enter the interior of the drainage ditch 5 in an organized manner, and the groundwater level can be controlled within a predetermined range. When the groundwater enters the interior of the catch well 6 through the drainage ditch 5, it will gradually accumulate in the catch well 6. At this time, according to the buoyancy of the groundwater, the floating ball 75 will rise inside the guide rod 74. As the water level rises, the floating ball 75 will be driven to contact the pressure sensor 76. At this time, after the pressure sensor 76 receives the pressure, it will start the operation of the water pump 72 through an external controller to pump the groundwater accumulated in the catch well 6 to the outside through the drain pipe 71, thereby reducing the buoyancy effect of the groundwater on the bottom plate body 2 and reducing the possibility of cracking of the bottom plate body 2, greatly improving the service life of the bottom plate body 2.
