Description

Technical Field

[0001] This utility model relates to the field of road construction technology, and in particular to an emergency drainage device for subway station foundation pit engineering. Background Technology

[0002] Emergency drainage systems for subway station foundation pits are crucial equipment for ensuring the safety and smooth progress of subway foundation pit construction. During subway construction, foundation pits are susceptible to water accumulation due to groundwater and rainwater. If not drained promptly, this can threaten the stability of the foundation pit and construction safety. These emergency drainage systems typically consist of high-efficiency water pumps, drainage pipes, and a water level monitoring system. The water pumps have powerful pumping capabilities, quickly removing accumulated water from the foundation pit. The drainage pipes are rationally laid out and designed to ensure smooth drainage, and some even utilize anti-clogging materials or structures to reduce the risk of blockage by silt and debris. The water level monitoring system can monitor the foundation pit water level in real time, automatically activating the drainage system when the water level reaches a set threshold, achieving intelligent drainage.

[0003] Currently, in existing technologies, water storage tanks are placed on the foundation pit for water storage. After grouting is required, the weight of the water storage tank will increase, causing it to sink deeper into the ground. Moreover, the water inrush in the foundation pit will cause the surrounding soil to soften, making the bottom of the water storage tank sink too deep into the ground, which will make it difficult to remove the water storage tank later. In particular, if the water storage tank drains too quickly, it will overturn the tank due to its own weight, causing the water to overturn the tank.

[0004] To address the problems in the existing technology, an emergency drainage device for subway station foundation pit engineering is provided. Utility Model Content

[0005] In view of this, this utility model proposes an emergency drainage device for subway station foundation pit engineering to solve the problems of the water storage tank sinking too deep into the ground after the weight is increased and the water surge overturning the water storage tank.

[0006] The technical solution of this utility model is implemented as follows: This utility model provides an emergency drainage device for subway station foundation pit engineering, including a water storage tank. A drainage pipe is welded to the upper end of the water storage tank. A closing valve is provided on the upper end of the drainage pipe, and grouting pipes are welded to both sides of the upper outer surface of the drainage pipe. A circular ring plate is welded to the lower end of the water storage tank. Rotating slots are opened at equal angles on the outer ring surface of the circular ring plate. Square long plates are fixedly connected inside the multiple rotating slots. Support components are provided on the outer side of the multiple square long plates. The lower end of the water storage tank is fitted inside the concrete, and the lower end of the water storage tank presses against the ground.

[0007] Furthermore, the support assembly includes a rotating plate with a groove on its upper part and a square slot on the bottom surface of the groove, which is fixedly engaged with the outer side of the square plate.

[0008] Furthermore, the groove slides within the rectangular plate on both sides.

[0009] Furthermore, a meshing hole is provided inside the lower end of the rotating plate. A screw is meshed inside this meshing hole.

[0010] Furthermore, a pressure plate is fixedly connected to the lower end face of the screw, and a support ball is connected to the lower end face of the pressure plate. The lower part of the outer surface of the support ball presses against the concrete above.

[0011] Furthermore, a handle is fixedly connected to the upper surface of the pressure plate at equal angles in a ring, and a knocking block is fixedly connected to the outer surface of the pressure plate at equal angles in a ring.

[0012] The present invention has the following advantages over the prior art:

[0013] (1) The emergency drainage device for subway station foundation pit project disclosed in this utility model prevents the rotating plate from shaking in the support by fastening the square long plate and the square slot, strengthens the fixation of the water storage tank, and after the rotating plate, screw and support ball are closed, the rotating plate is prevented from shaking randomly during the disassembly of the water storage tank, and the problem of the rotating plate colliding with the water storage tank is also avoided.

Detailed Implementation

[0023] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0024] like Figure 1 As shown, combined with Figure 2-4This utility model discloses an emergency drainage device for subway station foundation pit engineering, including a water storage tank 1. A drain pipe 11 is welded to the upper end of the water storage tank 1. A closing valve 12 is provided on the upper end of the drain pipe 11, and grouting pipes 13 are welded to both sides of the upper outer surface of the drain pipe 11. A circular ring plate 2 is welded to the lower end of the water storage tank 1. The outer ring surface of the circular ring plate 2 is provided with rotating slots 21 at equal angles. A square long plate 22 is fixedly connected inside the multiple rotating slots 21. Support components 3 are provided on the outer side of the multiple square long plates 22. The lower end of the water storage tank 1 is fitted inside the concrete, and the lower end of the water storage tank 1 presses against the ground. First, move the rotating plate 31 upwards, allowing the square slot 312 to disengage from both sides of the square plate 22. The square plate 22 then moves into the interior of the slide 311. Next, slowly rotate the rotating plate 31 downwards, causing the interior of the slide 311 to rotate downwards onto the outside of the square plate 22. Because the original length of the rotating plate 31 and screw 32 is higher than the lower end of the water tank 1, after the rotating plate 31 rotates downwards 180 degrees, the top of the slide 311 abuts against the upper surface of the square plate 22. The lower part of the outer surface of the support ball 34 faces the top of the concrete. Then, the worker turns the screw 32 counterclockwise using the handle 331, causing the screw 32 to be under force. The screw 32 is engaged counterclockwise inside the engagement hole 313, causing it to extend downwards. Simultaneously, the screw 32 drives the pressure plate 33 and the support ball 34 downwards. After the support ball 34 contacts the top of the concrete, the screw 32 is continued to be turned counterclockwise. Due to the force blocking the support ball 34, the downward force of the screw 32 is transmitted to the rotating plate 31, causing the rotating plate 31 to move upwards. As the rotating plate 31 gradually moves upwards, the square slot 312 engages with both sides of the square long plate 22. At this point, the screw 32 is stopped from being turned. The adjacent support assembly 3 follows the same working steps as above. After multiple support balls 34 provide support, the installation of the water storage tank 1 is completed. To increase the weight of the water storage tank 1, the water in the water storage tank 1 is first pumped out using the grouting pipe 13, and then cement is mixed in. The solidified cement adds weight to the water storage tank 1. After the water storage tank 1 is filled with gushing water, the closed valve 12 is opened through the automatic drainage system, and then the drainage pump is started to discharge the water in the water storage tank 1.

[0025] In this embodiment, the support assembly 3 includes a rotating plate 31. The upper part of the rotating plate 31 has a sliding groove 311, and the bottom surface of the sliding groove 311 has a square locking slot 312. The square locking slot 312 is fixedly engaged with the outer side of the square elongated plate 22. This helps prevent the rotating plate 31 from wobbling during support, strengthens the fixation of the water storage tank 1, and prevents the rotating plate 31 from wobbling randomly during the disassembly of the water storage tank 1 after the rotating plate 31, screw 32, and support ball 34 are retracted. It also avoids the rotating plate 31 from colliding with the water storage tank 1 during reciprocating movements.

[0026] In this embodiment, the sliding groove 311 is internally slidably fitted to both sides of the square long plate 22. When the water storage tank 1 is inserted too deeply into the ground during installation, the outer side of the original support ball 34 touches the ground and cannot rotate to 180 degrees, thus failing to properly support the operation of the water storage tank 1. At this time, by lifting the rotating plate 31 upward, the sliding groove 311 slides upward to both sides of the square long plate 22, allowing the rotating plate 31 and the support ball 34 to smoothly rotate downward 180 degrees, effectively preventing the outer side of the support ball 34 from getting stuck on the ground, improving functionality and practicality.

[0027] In this embodiment, the lower end of the rotating plate 31 has an engagement hole 313. A screw 32 is engaged inside the engagement hole 313, which facilitates the support of the water storage tank 1.

[0028] In this embodiment, a pressure plate 33 is fixedly connected to the lower end face of the screw 32, and a support ball 34 is connected to the lower end face of the pressure plate 33. The lower part of the outer surface of the support ball 34 presses against the concrete. This helps to keep the water storage tank 1 at the same height, effectively preventing the lower end of the water storage tank 1 from inserting too deeply into the ground, making it easier and more convenient to remove the water storage tank 1 later. Moreover, it prevents the water storage tank 1 from overturning due to rapid drainage, effectively strengthening the stability of the water storage tank 1.

[0029] In this embodiment, a handle 331 is fixedly connected to the upper surface of the pressure plate 33 at equal angles, and a knocking block 332 is fixedly connected to the outer surface of the pressure plate 33 at equal angles. The worker uses a hammer to strike the knocking block 332, causing the engagement hole 313 and the screw 32 to engage clockwise. The supporting ball 34 gradually moves upwards. After the supporting ball 34 leaves the concrete, the square slot 312 disengages from both sides of the square long plate 22. Then, the worker lifts the rotating plate 31 upwards. After the rotating plate 31 rotates 180 degrees, the supporting ball 34 is positioned above the water storage tank 1. Simultaneously, the square slot 312 engages with both sides of the square long plate 22, thus achieving the retraction of the rotating plate 31, screw 32, and supporting ball 34.

[0030] The working principle of this utility model is as follows:

[0031] In this invention, firstly, a layer of concrete is laid on the ground around the foundation pit, and then the water storage tank 1 is placed inside the concrete. Figure 3As shown), the lower end of the water storage tank 1 is inserted into the edge of the pit, thus forming a sealed state. Then, the rotating plate 31 is moved upward first, so that the square slot 312 is disengaged from both sides of the square long plate 22. The square long plate 22 moves into the interior of the slide groove 311. At this time, the rotating plate 31 is slowly rotated downward by hand, and the interior of the slide groove 311 rotates downward to the outside of the square long plate 22. Because the original length of the rotating plate 31 and the screw 32 is higher than the lower end of the water storage tank 1, after the rotating plate 31 rotates downward by 180 degrees, the top of the slide groove 311 abuts against the upper surface of the square long plate 22. The lower part of the outer surface of the support ball 34 faces the top of the concrete. The worker then turns the screw 32 counterclockwise through the handle 331. The screw 32, under force, engages counterclockwise with the inside of the engagement hole 313, causing the screw 32 to extend downward. At the same time, the screw 32 drives the pressure plate 33 and the support ball 34 downward. After the support ball 34 touches the top of the concrete, the screw 32 is turned counterclockwise. Because the support ball 34 is resisted, the downward force of the screw 32 is transmitted to the rotating plate 31, causing the rotating plate 31 to move upward. As the rotating plate 31 gradually moves upward, the square slot 312 engages with both sides of the square plate 22 (e.g., Figure 4 As shown), at this time, stop turning the screw 32. The adjacent support component 3 is in the same working steps as above. After multiple support balls 34 provide support, the installation of the water storage tank 1 is completed, followed by the installation of the subsequent automated drainage system, connecting pipes, etc.

[0032] When it is necessary to increase the weight of the water storage tank 1, the water in the water storage tank 1 is first pumped out using the grouting pipe 13, and then cement is mixed. The solidified cement adds weight to the water storage tank 1. In order to prevent the water storage tank 1 from moving downward and inserting too deeply into the ground, multiple support balls 34, multiple rotating plates 31, and multiple screws 32 are used to support the water storage tank 1 to keep it at the same height.

[0033] If the water tank 1 is full, the automatic drainage system opens the closed valve 12 and starts the drainage pump to discharge the water tank 1. If the water tank 1 is discharged too quickly, it will affect the weight of the water tank 1. Multiple support balls 34 are used to prevent the water tank 1 from being overturned.

[0034] During the disassembly of the water storage tank 1, due to the increased resistance to engagement of the meshing hole 313 and screw 32 after prolonged use, as well as the added weight of the cement, it is difficult for workers to manually turn the screw 32 clockwise using the handle 331. At this point, the worker uses a hammer to strike the striking block 332, causing the meshing hole 313 and screw 32 to mesh clockwise. The supporting ball 34 gradually moves upward. After the supporting ball 34 leaves the top of the concrete, the square slot 312 disengages from both sides of the square plate 22. Then, the worker lifts the rotating plate 31 upward. After the rotating plate 31 rotates 180 degrees, the supporting ball 34 is located at the top of the water storage tank 1. At the same time, the square slot 312 engages with both sides of the square plate 22, thereby achieving the retraction of the rotating plate 31, screw 32, and supporting ball 34.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
