Description

Technical Field

[0001] This utility model relates to the field of groundwater isolation technology in red beds, specifically a groundwater isolation construction structure for red beds. Background Technology

[0002] When the excavation depth of the foundation pit reaches a certain depth, it will reach the location of the red soil layer. Red soil generally has the characteristics of high porosity and high water content. The high porosity of red soil means that there are more voids in the same volume. This characteristic has a great impact on water infiltration and storage.

[0003] Existing technologies often have the following drawbacks: During construction, moisture in the laterite layer can easily seep into the foundation pit through pores, potentially leading to excessive water accumulation. Current water-stopping measures typically use sheet piles as waterstops on the sidewalls of the foundation pit. Because foundation pits are generally large, a large number of sheet piles are usually required. Moreover, to ensure the water-stopping effect, the sheet piles need to be tightly connected without large gaps. Each sheet pile needs to be welded to the adjacent sheet piles, and the welding quality must meet the requirements. This greatly increases the welding workload. Because the welding time for sheet piles is too long, the foundation pit remains in an ineffective water-stopping state for an extended period, allowing water from the laterite layer to continuously seep into the foundation pit. As the water accumulation increases, it affects construction conditions and delays the construction progress.

[0004] Therefore, this utility model provides a construction structure for waterproofing red-layer groundwater. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the cumbersome and time-consuming process of installing water-stop plates in the foundation pit through welding, and to propose a construction structure for water-stopping construction of red-layer groundwater.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a groundwater-proof construction structure for red-bedded groundwater, comprising a water-proof frame, the water-proof frame being composed of several water-proof plates, the two sides of the water-proof plates being wedge-shaped surfaces, the wedge-shaped surfaces of adjacent water-proof plates being compatible, and grooves being provided on the wedge-shaped surfaces of both sides of the water-proof plates, two trapezoidal frames being fixedly connected to one side of the water-proof plate, the two trapezoidal frames being respectively close to the two ends of the water-proof plate, and locking blocks being inserted into the adjacent trapezoidal grooves on the surfaces of the two water-proof plates, an extension arm being fixedly connected to the surface of the locking block, and a threaded rod being threaded through the surface of the extension arm, and a triangular plate being rotatably connected to the end of the threaded rod near the water-proof plate, the size of the triangular plate being compatible with the size of the groove.

[0007] The effects achieved by the above-mentioned components are: to facilitate the installation of the waterproofing plate, reduce the installation time, prevent a large amount of water from seeping from the sidewalls of the foundation pit into the area inside the foundation pit, and thus improve the efficiency of construction work.

[0008] Preferably, a round rod slides through the surface of the extension arm, and one end of the round rod is fixedly connected to the surface of the triangular plate.

[0009] The effect achieved by the above components is that the movement of the triangle causes the round rod to slide within the extension arm, and the extension arm restricts the movement path of the round rod, thereby restricting the movement path of the triangle and preventing the triangle from rotating during movement.

[0010] Preferably, a sealing gasket is fixedly connected to the surface of the triangular plate, and the surface of the sealing gasket is uniformly provided with diamond-shaped grooves. The sealing gasket is made of rubber.

[0011] The effect achieved by the above components is as follows: the triangular plate will press the sealing gasket at the position where the water-proof plates are attached, so that the sealing gasket can easily cover the joint of the water-proof plates, thereby improving the airtightness of the joint between the water-proof plates. When the sealing gasket is attached, it will be squeezed by the triangular plate. The sealing gasket will be easily deformed due to the diamond groove on its surface, thereby further improving the sealing effect of the sealing gasket.

[0012] Preferably, the inner wall of the baffle plate is provided with a cavity, and a plurality of water inlet strips are uniformly fixedly connected to one side of the baffle plate. A plurality of water inlet holes are uniformly opened on the inclined surface of the water inlet strips. The water inlet holes are connected to the cavity. A plurality of water pumping pipes are connected to one side of the baffle plate. The ends of the plurality of water pumping pipes away from the baffle plate are connected to a water collection pipe. The arc surface of the water collection pipe is connected to a connecting pipe.

[0013] The effect achieved by the above-mentioned components is as follows: water seeping out of the foundation pit will flow into the drainage ditch, and then flow into the cavity opened in the baffle plate through the water inlet hole on the surface of the water inlet strip. When the water pump is started, water will enter the water collection pipe from the water pumping pipe, and then enter the water pump from the water collection pipe into the connecting pipe, thereby pumping out the water seeping out of the area enclosed by the baffle plate in the foundation pit. This avoids the need to put the water pump into the foundation pit and move its position repeatedly to pump water, thereby reducing the workload of the workers.

[0014] Preferably, a display rod is slidably inserted into the surface of the water-blocking plate, one end of the display rod is fixedly connected to a float, and the other end of the display rod is fixedly connected to a display panel.

[0015] The effect achieved by the above components is as follows: the float will move the display rod by the rise of the water level in the cavity, and the movement of the display rod will move the display panel. By observing the height of the rise of the display panel, the construction personnel can understand the water level in the cavity, and thus make it easier for the staff to control the start and stop of the water pump according to the water level, so as to avoid the water pump being turned on when the water volume is too low, thus avoiding the waste of energy used by the water pump.

[0016] Preferably, the surface of the display rod is covered with a filter screen, and both ends of the filter screen are fixedly connected to the inner wall of the water-proof plate.

[0017] The above components achieve the following effect: the float moves within the filter screen, and the filter screen prevents sludge from entering the cavity through the water inlet and hindering the movement of the float.

[0018] In summary:

[0019] 1. In this utility model, by setting up a water-proof structure, a drainage groove is opened near the wall in the foundation pit. Then, several water-proof plates are placed in the drainage groove, so that the water-proof plates are respectively attached to the side walls of the foundation pit. At this time, the wedge-shaped surfaces of adjacent water-proof plates are all in contact with each other. Then, a locking block is placed into the adjacent trapezoidal groove. After the locking block is inserted into the trapezoidal groove, the threaded rod is rotated. The rotation of the threaded rod will move within the extension arm by means of the thread. The movement of the threaded rod will drive the triangular plate to move closer to the water-proof plate. When the triangular plate moves to the appropriate position, the triangular plate will simultaneously lock into two grooves and apply pressure to the two water-proof plates. The triangular plate reaches the position of the water-proof plate, thereby further limiting the water-proof plate and preventing the water-proof plate from tilting at the bottom due to pressure. By confining the water-proof plate within the foundation pit, the water seeping from the side walls of the foundation pit is prevented from flowing into the foundation pit. This convenient method of installing the water-proof plate reduces the installation time required and prevents a large amount of water seeping from the side walls of the foundation pit into the area inside the foundation pit, thereby improving the construction efficiency.

Detailed Implementation

[0026] Reference Figure 1 As shown, this utility model provides a technical solution: a water-proof construction structure for red-layer groundwater, including a water-proof frame, which is composed of several water-proof plates 1. The two sides of the water-proof plate 1 are wedge-shaped surfaces, and the wedge-shaped surfaces of adjacent water-proof plates 1 are matched. Grooves 7 are opened on the wedge-shaped surfaces on both sides of the water-proof plate 1. Two trapezoidal frames 2 are fixedly connected to one side of the water-proof plate 1. The two trapezoidal frames 2 are respectively close to the two ends of the water-proof plate 1. A locking block 3 is inserted into the adjacent trapezoidal grooves on the surface of the two water-proof plates 1. An extension arm 4 is fixedly connected to the surface of the locking block 3. A threaded rod 5 is threaded through the surface of the extension arm 4. A triangular plate 6 is rotatably connected to the end of the threaded rod 5 close to the water-proof plate 1. The size of the triangular plate 6 is matched with the size of the groove 7. The water-proof plate 1 is installed in a convenient way, which reduces the installation time and prevents a large amount of water from seeping from the side wall of the foundation pit into the area inside the foundation pit, thereby improving the construction efficiency.

[0027] Reference Figure 2 and Figure 3 As shown in this embodiment: a round rod 8 slides through the surface of the extension arm 4. One end of the round rod 8 is fixedly connected to the surface of the triangular plate 6. The movement of the triangular plate 6 will cause the round rod 8 to slide within the extension arm 4. The extension arm 4 restricts the movement path of the round rod 8, thereby restricting the movement path of the triangular plate 6 and preventing the triangular plate 6 from rotating during movement. A sealing gasket 9 is fixedly connected to the surface of the triangular plate 6. The surface of the sealing gasket 9 is uniformly provided with diamond-shaped grooves. The sealing gasket 9 is made of rubber. The triangular plate 6 will press the sealing gasket 9 at the position where the water-proof plates 1 are attached. The sealing gasket 9 can easily cover the joint of the water-proof plates 1, thereby improving the airtightness of the joint between the water-proof plates 1. When the sealing gasket 9 is attached, it will be squeezed by the triangular plate 6. The sealing gasket 9 will easily deform due to the diamond-shaped grooves on its surface, thereby further improving the sealing effect of the sealing gasket 9.

[0028] Reference Figure 4 and Figure 5As shown, specifically, the inner wall of the baffle plate 1 is provided with a cavity 10. Several water inlet strips 11 are uniformly fixedly connected to one side of the baffle plate 1. Several water inlet holes 12 are uniformly opened on the inclined surface of the water inlet strips 11. The water inlet holes 12 are connected to the cavity 10. Several water pumping pipes 13 are connected to one side of the baffle plate 1. The end of the several water pumping pipes 13 away from the baffle plate 1 is connected to a water collection pipe 14. The arc surface of the water collection pipe 14 is connected to a connecting pipe 15. The water seeping out of the foundation pit will flow into the drainage ditch, and then flow into the cavity 10 opened in the baffle plate 1 from the water inlet holes 12 on the surface of the water inlet strips 11. When the water pump is started, the water will enter the water collection pipe 14 from the water pumping pipe 13, enter the connecting pipe 15 from the water collection pipe 14, and then enter the water pump. This will pump out the water seeping out of the area enclosed by the baffle plate 1 in the foundation pit, avoiding the need to constantly move the water pump in the foundation pit to pump water, thereby reducing the workload of the workers. A display rod 16 is slidably inserted into the surface of the baffle plate 1. One end of the display rod 16 is fixedly connected to a float 17, and the other end is fixedly connected to a display panel 18. The float 17 moves the display rod 16 as the water level in the cavity 10 rises, which in turn moves the display panel 18. By observing the height the display panel 18 rises, construction personnel can determine the water level in the cavity 10, allowing them to control the start and stop of the water pump based on the water level, thus preventing the pump from running due to insufficient water and wasting energy. A filter screen 19 is fitted onto the surface of the display rod 16. Both ends of the filter screen 19 are fixedly connected to the inner wall of the baffle plate 1. The float 17 moves within the filter screen 19 as it moves, preventing sludge from entering the cavity 10 through the inlet hole 12 and hindering the movement of the float 17.

[0029] The working principle is as follows: When construction is required on the foundation pit, a drainage groove is first opened near the wall inside the pit. Then, several water-resistant plates 1 are placed into the drainage groove, so that the water-resistant plates 1 are respectively attached to the side walls of the foundation pit. At this time, the wedge-shaped surfaces of adjacent water-resistant plates 1 are in contact with each other. Then, the locking block 3 is placed into the adjacent trapezoidal groove. After the locking block 3 is inserted into the trapezoidal groove, the threaded rod 5 is rotated. The rotation of the threaded rod 5 will move within the extension arm 4 by means of the thread. The movement of the threaded rod 5 will drive the triangular plate 6 to move closer to the water-resistant plate 1. The movement of the triangular plate 6 will drive the round rod 8 to slide within the extension arm 4. The extension arm 4 restricts the movement path of the round rod 8, thereby restricting the movement path of the triangular plate 6, thus preventing the triangular plate 6 from rotating during movement. When the triangular plate 6 moves to the appropriate position, it will simultaneously engage the sealing gasket 9 into the two grooves 7 and apply pressure to the two water-blocking plates 1. At this time, the water-blocking plates 1 will cause the sealing gasket 9 to fit tightly against the two water-blocking plates 1 at the contact position. The triangular plate 6 reaches the position of the water-blocking plate 1, thereby further limiting the water-blocking plate 1 and preventing it from tilting at the bottom due to pressure. By restricting the water-blocking plate 1 within the pit, The sealing gasket 9 serves to prevent water seeping from the sidewalls of the foundation pit from flowing into the pit. It also covers the joint between the water-proof plates 1, improving the airtightness of the joint. During installation, the sealing gasket 9 is compressed by the triangular plate 6, and its surface, with its diamond-shaped grooves, easily deforms, further enhancing its sealing effect. After the water-proof plates 1 are installed, the water pump is connected to the connecting pipe 15. The foundation pit is then surrounded by the water-proof plates 1, and water seeping from the pit flows into the drainage ditch, then into the water-proof plates through the inlet holes 12 on the surface of the inlet strip 11. Within the cavity 10, the float 17 moves the display rod 16 as the water level rises. The float 17 moves within the filter screen 19, and the display rod 16 moves the display panel 18. By observing the height of the display panel 18, the construction personnel can determine the water level within the cavity 10 and control the start and stop of the water pump. When the display panel 18 rises to a certain height, the water pump is started, and water enters the collection pipe 14 from the pumping pipe 13, then the connecting pipe 15 from the collection pipe 14, and finally enters the water pump, thereby pumping out the water seeping out within the area enclosed by the baffle plate 1 in the foundation pit.
