Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to an anti-buoyancy structure for underground engineering that is easy to assemble. Background Technology

[0002] Underground engineering refers to underground civil engineering projects constructed below ground level for the development and utilization of underground space resources. It includes underground houses and structures, underground railways, highway tunnels, underwater tunnels, underground utility tunnels, and pedestrian underpasses. Waterproofing is crucial for underground engineering projects, and should follow the principle of "combining prevention, drainage, interception, and blocking, adapting to local conditions, and comprehensive management." Furthermore, the construction of underground projects is subject to the buoyancy of groundwater, which may lead to damage to the building's foundation slab, cracking at beam-column joints, and other issues. Therefore, groundwater drainage and anti-buoyancy measures are extremely important for underground engineering projects, necessitating a convenient and modular anti-buoyancy structure.

[0003] Chinese patent document CN216194972U discloses an anti-buoyancy structure for underground engineering, including a valve plate, an anchor rod frame, and a water removal component. The anchor rod frame extends into and is fixed to the inside of the valve plate. A water removal component, movably connected to the inside of the anchor rod frame, is pre-installed on the inside of the anchor rod frame. The water removal component includes a stabilizing frame, a straight rod, a water-pulling block, and a skirt. In this anti-buoyancy structure for underground engineering, the anchor rod frame extends into and is fixed to the inside of the valve plate. The water removal component inside the anchor rod frame is a movable part. When there is groundwater in the underground where the anchor rod frame is located, the groundwater can seep into the inside of the anchor rod frame. By lifting the water removal component upwards, the groundwater accumulated inside the anchor rod frame can be removed, thus achieving the anti-buoyancy effect. After the entire device is installed, groundwater removal operations can be carried out adaptively according to needs. The operation process is simple, and the removal of groundwater can effectively improve the anti-buoyancy effect of underground engineering and ensure the overall stability of the building.

[0004] The existing technology has the following problems:

[0005] While easy-to-assemble underground anti-buoyancy structures are designed for easy splicing, it is inconvenient to excavate, splice, and fix multiple devices during use, resulting in inconvenience in use.

The outer walls of the left and right portions of the two connecting components are fixedly installed to the inner cavities of the opposing portions of valve plate 1 and valve plate 2, respectively.

[0012] Preferably, an L-shaped small block is fixedly connected to the left part of the upper surface of the L-shaped block one, and the outer wall of the L-shaped small block one is movably sleeved with the inner cavity of the valve plate one. An L-shaped small block two is fixedly connected to the right part of the upper surface of the L-shaped block two, and the outer wall of the L-shaped small block two is movably sleeved with the inner cavity of the valve plate two.

[0013] Preferably, the connecting assembly includes a U-shaped clamping plate, the inner wall of which is respectively engaged with the outer walls of L-shaped clamping block one and L-shaped clamping block two, the outer wall of which is engaged with the inner cavity of the opposite portion of valve plate one and valve plate two, and screw one is threadedly connected to the inner cavity of the left and right portions of the U-shaped clamping plate, the outer walls of the two screws one being threadedly connected to the inner cavity of the opposite portion of valve plate one and valve plate two, respectively.

Then, under the action of two screws one, the U-shaped locking plate is fixed in the inner cavity of the opposite part of valve plate one and valve plate two respectively. Through the action of the U-shaped locking plate, L-shaped locking blocks one and two are restricted and fixed, thereby completing the splicing. In particular, the action of small L-shaped locking blocks one and two further increases the restrictive force when L-shaped locking blocks one and two press against valve plate one and valve plate two, thereby improving the stability of the splicing.

Then, a fixing rod is inserted through the inner cavity of the guide rod and moved to one side of the fixing rod. Under the action of the two fixing rods, the fixing rod more firmly supports and secures valve plate one and valve plate two, facilitating installation. The screws further secure the fixing block within the inner cavity of the guide rod, thus restricting and fixing the fixing rod, improving stability while facilitating installation and disassembly.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] like Figure 1 As shown, a conveniently assembled anti-buoyancy structure for underground engineering includes a valve plate 1, a valve plate 2 overlapping the right side of the valve plate 1, two splicing components 3 slidably connected to the inner cavities of the left parts of both valve plate 1 and valve plate 2, two splicing components 4 slidably connected to the inner cavities of the right parts of both valve plate 1 and valve plate 2, the opposing surfaces of the two splicing components 3 and the two splicing components 4 located in the middle are interlocked, two connecting components 5 are interlocked to the outer walls of the two splicing components 3 and the two splicing components 4 located in the middle, the outer walls of the left and right parts of the two connecting components 5 are fixedly installed to the inner cavities of the opposing parts of valve plate 1 and valve plate 2, respectively, and fixing components 6 are fixedly connected to the lower surfaces of the central parts of both valve plate 1 and valve plate 2.

[0028] First, under the action of fixing component 6, valve plate 1 is fixed. Then, valve plate 2 is fixed to the right side of valve plate 1. Next, the two splicing components 4 on the right side of valve plate 1 are moved and flipped, so that the two splicing components 4 move into the inner cavity of the left side of valve plate 2. Then, the two splicing components 3 on the left side of valve plate 2 are flipped and moved, so that the inner wall of the two splicing components 3 can be engaged with the inner wall of the two splicing components 4. Then, connecting component 5 is engaged with the outer wall of the two splicing components 3 and the two splicing components 4, and the connecting component 5 is fixed, thereby restricting the splicing components 3 and 4. Through the action of splicing components 3, splicing components 4 and connecting component 5, valve plate 1 and valve plate 2 can be stably spliced ​​together.

[0029] like Figure 2 , Figure 3As shown, splicing component 1 3 includes a limiting rod 31, the front and rear parts of the outer wall of the limiting rod 31 are slidably connected to the inner cavity of the valve plate 1, and an L-shaped locking block 32 is fixedly connected to the middle of the outer wall of the limiting rod 31, the outer wall of the L-shaped locking block 32 is locked to the inner cavity of the valve plate 1; splicing component 2 4 includes a limiting rod 41, the front and rear parts of the outer wall of the limiting rod 41 are slidably connected to the inner cavity of the valve plate 2, and an L-shaped locking block 42 is fixedly connected to the middle of the outer wall of the limiting rod 41, the outer wall of the L-shaped locking block 42 is locked to the inner cavity of the valve plate 2.

[0030] When the right side of valve plate 1 overlaps with the left side of valve plate 2, firstly rotate and stand up the L-shaped locking block 32 on the left side of valve plate 2, then rotate and stand up the L-shaped locking block 42 on the right side of valve plate 1. Next, move the L-shaped locking block 42 to the left and then flip it over so that the upper surface of the L-shaped locking block 42 overlaps with the bottom of the inner cavity of valve plate 1. Then, move the L-shaped locking block 32 to the right and flip it over so that the upper surface of the L-shaped locking block 32 overlaps with the bottom of the inner cavity of valve plate 2. At this time, the inner walls of the opposite parts of the L-shaped locking block 32 and the L-shaped locking block 42 interlock with each other, thereby connecting and restricting valve plate 1 and valve plate 2.

[0031] The left part of the upper surface of L-shaped block 32 is fixedly connected to L-shaped small block 33. The outer wall of L-shaped small block 33 is movably sleeved with the inner cavity of valve plate 1. The right part of the upper surface of L-shaped block 42 is fixedly connected to L-shaped small block 43. The outer wall of L-shaped small block 43 is movably sleeved with the inner cavity of valve plate 2.

[0032] Through the action of L-shaped small clamp 33 and L-shaped small clamp 43, when L-shaped small clamp 32 and L-shaped small clamp 42 press against each other, the restraining force can be further increased, thereby improving the stability of the splicing.

[0033] like Figure 4 As shown, the connecting component 5 includes a U-shaped clamping plate 51. The inner wall of the U-shaped clamping plate 51 is respectively engaged with the outer walls of L-shaped clamping block 32 and L-shaped clamping block 42. The outer wall of the U-shaped clamping plate 51 is engaged with the inner cavity of the opposite part of valve plate 1 and valve plate 2. The inner cavities of the left and right parts of the U-shaped clamping plate 51 are threaded with screws 52. The outer walls of the two screws 52 are respectively threaded with the inner cavities of the opposite part of valve plate 1 and valve plate 2.

[0034] The U-shaped clamp 51 is snapped onto the outer wall of the flipped L-shaped clamp 32 and L-shaped clamp 42, thus restricting the L-shaped clamp 32 and L-shaped clamp 42. Then, under the action of the two screws 52, the U-shaped clamp 51 is fixed in the inner cavity of the opposite part of the valve plate 1 and valve plate 2 respectively. Through the action of the U-shaped clamp 51, the L-shaped clamp 42 and L-shaped clamp 32 are restricted and fixed, thereby completing the splicing.

[0035] like Figure 5 As shown, the fixing component 6 includes a fixing rod 61, the upper surface of which is fixedly connected to the lower surface of the valve plate 1. Two symmetrical auxiliary components 62 are fixedly connected to the inner cavity of the fixing rod 61, and the two auxiliary components 62 are located between the splicing component 3 and the splicing component 4. The two auxiliary components 62 include two guide rods 621, the outer walls of the upper part of the two guide rods 621 are fixedly connected to the inner cavities of the left and right parts of the valve plate 1 respectively. A fixing insert rod 622 is inserted into the inner cavity of the guide rod 621, and a fixing block 623 is fixedly connected to the upper surface of the fixing insert rod 622. The outer wall of the fixing block 623 is engaged with the inner cavity of the upper part of the guide rod 621.

[0036] The fixing rod 61 enables the valve plate 1 and valve plate 2 to be initially fixed. Then, the fixing rod 622 is passed through the inner cavity of the guide rod 621 and moved to one side of the fixing rod 61. Under the action of the two fixing rods 622, the fixing rod 61 can more stably support and fix the valve plate 1 and valve plate 2, thus facilitating operation during installation.

[0037] like Figure 6 As shown, the inner cavity of the fixing block 623 is threaded with two screws 624, and the outer walls of the lower part of the two screws 624 are respectively threaded with the inner cavity of the guide rod 621.

[0038] The screw 624 allows the fixing block 623 to be fixed in the inner cavity of the guide rod 621, thereby fixing the fixing rod 622, improving stability and facilitating installation and disassembly.

[0039] The working principle of this utility model is as follows: First, the fixing rod 61 initially fixes valve plate 1 and valve plate 2. Then, the fixing rod 622 passes through the inner cavity of the guide rod 621 and moves to one side of the fixing rod 61. Under the action of the two fixing rods 622, the fixing rod 61 can more stably support and fix valve plate 1 and valve plate 2. When the right side of valve plate 1 overlaps with the left side of valve plate 2, firstly, rotate and stand up the L-shaped locking block 32 on the left side of valve plate 2, then rotate and stand up the L-shaped locking block 42 on the right side of valve plate 1. Then, move the L-shaped locking block 42 to the left and flip it over so that the upper surface of the L-shaped locking block 42 overlaps with the bottom of the inner cavity of valve plate 1. Then, in the same way, move the L-shaped locking block 32... Move to the right and flip it over so that the upper surface of L-shaped block 32 overlaps with the bottom of the inner cavity of valve plate 2. At this time, the inner walls of the opposite parts of L-shaped block 32 and L-shaped block 42 interlock with each other. Then, the U-shaped plate 51 is snapped onto the outer wall of the flipped L-shaped block 32 and L-shaped block 42, thus restricting L-shaped block 32 and L-shaped block 42. Then, under the action of the two screws 52, the U-shaped plate 51 is fixed in the inner cavity of the opposite parts of valve plate 1 and valve plate 2. Through the action of the U-shaped plate 51, L-shaped block 42 and L-shaped block 32 are restricted and fixed, thus completing the splicing. Through the action of L-shaped block 32, L-shaped block 42 and U-shaped plate 51, valve plate 1 and valve plate 2 can be stably spliced ​​together.
