[0024] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0025] This utility model provides a pressure relief well with a permanent pressure relief effect through improvement. The technical solution of this utility model is as follows:

[0026] like Figures 1-5 As shown, a pressure relief well with permanent pressure relief effect includes a base plate 1, a pressure relief well 3 inside the base plate 1, and a floor slab 2 poured on the base plate 1. Before pouring the floor slab 2, a 500mm*500mm size (the size can be adjusted according to the actual site conditions) is reserved at the position of the pressure relief well 3. The concrete floor slab 2 is not poured, and an opening is reserved for later installation of a cover plate 9. The well also includes:

[0027] Steel plate 4 is fixedly connected inside pressure relief well 3. Pressure relief pipe 5 is fixedly connected to steel plate 4. Ball valve 6 is installed on the upper part of pressure relief pipe 5. Ball valve 6 serves as a pressure regulating device. High-strength grout 7 is installed on steel plate 4 to seal the periphery of pressure relief pipe 5. Cover plate 9 is movably inserted into the ground 2. Through multi-layer structure design and end installation of ball valve 6, water can be directly connected for pressure relief in the future, achieving a long-term stable pressure relief effect. Moreover, leakage at pressure relief well 3 can be repaired in time, reducing leakage at ground 2.

[0028] Furthermore, such as Figure 2 and Figure 4 As shown, four slots 8 are provided on the ground 2, and a groove 10 is provided inside the cover plate 9. The cross section of the groove 10 is in the shape of a cross.

[0029] Furthermore, such as Figures 2-4 As shown, four locking plates 11 are slidably connected in the groove 10. The four locking plates 11 are respectively adapted to the four locking slots 8. Four limiting posts 12 are fixedly connected to the four locking plates 11 respectively. The limiting posts 12 are arranged in a ring array with the center of the rotating plate 15 as the center.

[0030] Furthermore, such as Figure 3 As shown, multiple connecting plates 13 are fixedly connected to the four plates 11 respectively. The two adjacent connecting plates 13 are symmetrical about the corresponding plates 11. Multiple springs 14 are fixedly connected to the multiple connecting plates 13 respectively. The multiple springs 14 are fixedly connected inside the cover plate 9.

[0031] Furthermore, such as Figures 1-5 As shown, a rotating plate 15 is rotatably connected to the cover plate 9. The rotating plate 15 has four limiting grooves 16 and four limiting posts 12 are respectively located in the four limiting grooves 16. When the rotating plate 15 is rotated, the limiting posts 12 will move in the limiting grooves 16 as it rotates, causing the locking plate 11 to move inward and away from the locking groove 8, thus releasing the restriction on the cover plate 9.

[0032] Furthermore, such as Figures 1-5 As shown, the rotating plate 15 has a slot 17. The cross-section of the slot 17 is a regular hexagon. Only a hexagonal screwdriver of a specific size can be inserted into the slot 17 to drive the rotating plate 15 to rotate, thus preventing unauthorized personnel from opening the cover plate 9 and operating the ball valve 6, which could cause danger.

[0033] The specific working method is as follows: Before pouring the concrete floor 2, a 500mm*500mm opening (the size can be adjusted according to the actual site conditions) is reserved at the location of the pressure relief well 3. The concrete floor 2 is not poured, and an opening is reserved for the later installation of the cover plate 9. The pressure relief pipe 5 is vertically installed as the main pressure relief channel. A steel plate 4 is welded to the bottom of the pressure relief pipe 5 for reinforcement. The steel plate 4 is welded to the inside of the pressure relief well 3 to ensure structural stability. A ball valve 6 is installed on the upper part of the pressure relief pipe 5 as a pressure regulating device. During the flood season, the ball valve 6 can be directly opened to drain water and relieve pressure. Finally, high-strength grout 7 is used to seal the perimeter of the pressure relief pipe 5. Then, a hexagonal screwdriver of a specific size is inserted into the slot 17, and the rotating plate 15 is rotated, causing the limiting groove 16 to rotate. Since the limiting post 12 is located in the limiting groove 16, the limiting post 12 moves with the rotation of the rotating plate 15, causing the clamping plate 11 to move towards the cover plate 9. When the clamping plate 11 is fully embedded in the cover plate 9... After placing the cover plate 9 into the pre-reserved opening, align the retaining plate 11 with the retaining groove 8, then pull out the hex screwdriver. The connecting plate 13 will reset under the action of the spring 14, causing the retaining plate 11 to move outward, so that the retaining plate 11 is embedded in the retaining groove 8, fixing the cover plate 9 at the opening to prevent unauthorized personnel from opening the cover plate 9 and operating the ball valve 6, which could cause danger. When maintenance is needed later, repeat the above operation to embed the retaining plate 11 into the cover plate 9, and the cover plate 9 can be removed for easy water diversion maintenance later.

[0034] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
