Description

Technical Field

[0001] The utility model relates to the technical field of protective structures, in particular to a water-stopping protective structure for a foundation pit used in foundation construction. Background Art

[0002] A protective structure is a structural form designed to protect a system, equipment or structure from the external environment or internal conditions. Its design and application are extensive and involve many fields, including but not limited to mechanical engineering, civil engineering, construction engineering and nuclear power plant safety systems.

[0003] At present, in order to prevent groundwater from seeping into the foundation pit, operators generally use water-stopping protection structures to keep the inside of the foundation pit dry. However, the water-stopping protection structure simply blocks the groundwater outside the foundation pit and is unable to drain the accumulated water. This causes the inner wall of the foundation pit to be in a wet state for a long time, resulting in a decrease in the overall stability of the foundation pit and causing safety issues such as slippage and collapse of the foundation pit slope. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that when the above-mentioned equipment is in use, the stability of the foundation pit is reduced due to the inability to discharge the accumulated water, and thus a water-stopping protection structure for the foundation pit in foundation construction is proposed.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a water-stopping protection structure for foundation pits in foundation construction, comprising a base plate, the outer wall of the base plate is fixedly installed with two hinges, a support plate is fixedly installed between the outer walls of the two hinges, the top of the base plate is fixedly installed with four threaded holes, the inner walls of the four threaded holes are threadedly connected with an adjusting threaded rod, the top of the base plate is provided with two sliding grooves, the inner walls of the two sliding grooves are movably embedded with sliders, the outer walls of the two sliders are provided with threaded holes, the inner walls of the two threaded holes are threadedly connected with adjusting threaded rods, and the outer walls of the two adjusting threaded rods are movably inserted into the inside of the base plate, the tops of the two sliders are fixedly installed with ear blocks with holes, and the inner walls of the two ear blocks with holes are movably inserted with connecting force arms.

[0006] Preferably, the outer walls of the two connecting force arms are movably sleeved with two ear blocks with holes, and the outer walls of the two ear blocks with holes are fixedly connected to one side of the outer wall of the support plate.

[0007] Preferably, a group of circular holes is opened on one side of the outer wall of the support plate, and a group of water pipes are fixedly inserted into the inner surface walls of the group of circular holes.

[0008] Preferably, two guide rails are fixedly mounted on one side of the outer wall of the support plate, and circular grooves are formed on the tops of the two guide rails.

[0009] Preferably, the inner surface walls of the two circular grooves are movably inserted with a rotating shaft, and the outer surface walls of the two rotating shafts are fixedly sleeved with a baffle.

[0010] Preferably, a second slide block is movably inserted into the inner surface walls of the two guide rails, and the bottoms of the two baffles are in contact with the tops of the second slide block.

[0011] Preferably, a water tank is fixedly installed between the outer walls of the two sliding blocks 2, and a handle is fixedly installed on one side of the outer wall of the water tank.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] 1. In the utility model, after the device closely fits the baffle plate with the inside of the foundation pit, the groundwater accumulated in the soil can be discharged through a group of water pipes and enter the vertical interior below for unified collection and treatment. The device can timely discharge the accumulated water on the inner wall of the foundation pit to prevent the slope of the foundation pit from being washed and soaked by groundwater for a long time, thereby maintaining the shear strength of the soil and the overall stability of the foundation pit. Timely discharge of groundwater can also reduce the corrosion of the device by accumulated water, thereby extending the service life of the device. The operating box rotates the baffle plate and the rotating shaft, and the water tank can be quickly removed by the handle to prevent the groundwater inside the water tank from overflowing and causing water accumulation inside the foundation pit.

[0014] 2. In the utility model, by rotating and adjusting the threaded rod 2, the support plate can be driven to move and fit with the inner wall of the foundation pit, thereby avoiding deformation and displacement of the inner wall of the foundation pit and improving the stability of the foundation pit. When the device is in use, the operator can rotate the adjusting threaded rod 1 to drill into the soil to prevent the device from being displaced during use and affecting the results of use.

[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides a foundation pit water-stopping protection structure for foundation construction, including a bottom plate 1, two hinges 2 are fixedly installed on the outer wall of the bottom plate 1, a support plate 3 is fixedly installed between the outer walls of the two hinges 2, four threaded holes 4 are fixedly installed on the top of the bottom plate 1, the inner walls of the four threaded holes 4 are all threadedly connected with an adjusting threaded rod 5, two slide grooves 6 are provided on the top of the bottom plate 1, the inner walls of the two slide grooves 6 are movably embedded with a slider 7, and the outer walls of the two sliders 7 are provided with A threaded hole 28, the inner walls of the two threaded holes 28 are threadedly connected with an adjusting threaded rod 29, and the outer walls of the two adjusting threaded rods 29 are movably inserted into the interior of the bottom plate 1, the tops of the two sliders 17 are fixedly installed with a perforated ear block 10, the inner walls of the two perforated ear blocks 10 are movably inserted with a connecting force arm 11, the outer walls of the two connecting force arms 11 are movably sleeved with a perforated ear block 212, and the outer walls of the two perforated ear blocks 12 are fixedly connected to one side of the outer wall of the support plate 3.

[0024] The effect achieved by the entire embodiment 1 is that the operator first fits the device to one side of the inner wall of the foundation pit, and then rotates and adjusts the threaded rod 5 to make it rotate and drill into the soil under the action of the threaded hole 4 to prevent the device from being displaced during use and affecting the waterproof effect. After the operator rotates and adjusts the threaded rod 29, the threaded rod 29 can be adjusted to make the ear block 10 with holes move together through the slider 7, and push the connecting force arm 11 to start moving. The connecting force arm 11 pushes the support plate 3 to the inner wall of the foundation pit through the ear block 2 with holes 12, so that it is tightly fitted with one side of the inner wall of the foundation pit, preventing the foundation pit from collapsing, landslides, etc., and improving construction safety.

[0025] Embodiment 2, as Figure 2-Figure 4 As shown, it is characterized in that: a group of circular holes 13 are opened on one side of the outer wall of the support plate 3, a group of water pipes 14 are fixedly inserted on the inner wall of the group of circular holes 13, two guide rails 15 are fixedly installed on one side of the outer wall of the support plate 3, circular grooves 16 are opened on the tops of the two guide rails 15, and rotating shafts 17 are movably inserted on the inner walls of the two circular grooves 16, and baffles 18 are fixedly sleeved on the outer walls of the two rotating shafts 17, and sliders 19 are movably inserted on the inner walls of the two guide rails 15, and the bottoms of the two baffles 18 are in contact with the tops of the sliders 19, a water tank 20 is fixedly installed between the outer walls of the two sliders 19, and a handle 21 is fixedly installed on one side of the outer wall of the water tank 20.

[0026] The effect achieved by the entire embodiment 2 is that the support plate 3 can prevent groundwater from penetrating into the interior of the foundation pit, prevent groundwater from pouring into the foundation pit, and affect the construction safety and progress. The groundwater accumulated on one side of the outer wall of the device can flow into the water tank 20 through the water pipe 14. The accumulated water can be discharged in time through the water pipe 14 to prevent the soil on one side of the inner wall of the foundation pit from being soaked in water for a long time, thereby reducing the stability of the foundation pit. When the operator needs to remove the water tank 20, the baffle 18 can be driven to rotate by the rotating shaft 17, so that the baffle 18 cancels the limit on the slider 19. Then the operator can remove the water tank 20 through the handle 21, and pour out the accumulated water in time to prevent the accumulated water from overflowing into the interior of the foundation pit and causing inconvenience to the workers' construction.

[0027] Working principle: When the device is in use, the operator can fit one side of the outer wall of the device with one side of the inner wall of the foundation pit, and then rotate the adjusting threaded rod 5 to drill into the ground to fix the device, and then rotate the two adjusting threaded rods 9 in the same direction to make it start to rotate inside the bottom plate 1. When the adjusting threaded rod 9 rotates, it will drive the slider 7 of the outer wall to rotate together, and the slider 7 will move under the action of the slide groove 6, driving the top ear block 10 with holes to move together. When the ear block 10 with holes moves, it will drive the connecting force arm 11 to start moving, and the connecting force arm 11 makes the ear block 2 with holes 12 move upward. The ear block 2 with holes 12 will push the support plate 3 to start moving, so that it starts to rotate on the outer walls of the two hinges 2 and connects with the inner wall of the foundation pit. One side fits tightly, so that the inside of the foundation pit remains stable. The support plate 3 can also prevent groundwater from penetrating into the inside of the foundation pit, causing excessive water accumulation inside the foundation pit to affect the construction. When the groundwater reaches one side of the outer wall of the support plate 3, it can flow through a group of water pipes 14, and then the groundwater flows out from the inside of the water pipes 14 and falls into the water tank 20 below. The water tank 20 can collect the groundwater in a unified manner. When there is too much groundwater in the water tank 20, the operator can rotate the shaft 17 so that the shaft 17 starts to rotate inside the circular groove 16. The shaft 17 will cause the baffle 18 to rotate together. Then the operator can move the water tank 20 through the handle 21, so that the slider 19 can be pulled out from the inside of the guide rail 15, which is convenient for the operator to pour out the groundwater inside the water tank 20.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
