Description
Technical Field
[0001] The present application relates to the technical field of ground-connected wall construction, and in particular to a water bag sealing structure for underground continuous wall joints. Background Art
[0002] Underground continuous wall, also known as ground-connected wall, is a mature underground building structure. With the development of modern construction projects, especially in the construction of underground structures such as subway stations, underground shopping malls, underground garages and other projects, underground continuous wall, as the retaining structure of Central Asia, its construction quality and efficiency are crucial to the success of the entire project.
[0003] The construction method of the ground-connected wall is generally as follows: use an excavator to dig a slot section in the underground jump where the ground-connected wall is pre-installed, then install an I-beam vertically in the slot section, then install a pre-welded steel cage between the connected I-beams, and then pour concrete into the steel cage. In order to facilitate the lowering of the steel cage into the slot of the I-beam, the outer contour of the steel cage generally leaves a gap with the slot wall of the I-beam. When pouring concrete, the concrete flows along the gap between the leading steel cage and the slot wall to the unconstructed rear width area, resulting in an unsafe structure of the ground-connected wall and increasing the construction difficulty of installing the ground-connected wall in the rear width area. For this reason, in the prior art, a flexible water bag is installed in the back slot of the I-beam of the ground-connected wall, that is, in the rear width to solve the concrete bypass problem, and the flexible water bag is hoisted out by a crane after the concrete in the steel cage is solidified.
[0004] When the water bag is hoisted out, the outer surface of the water bag needs to be cleaned. Under the current circumstances, manual cleaning is often used. However, the flexible water bag is in a cylindrical state when it is hoisted out. When cleaning the cylindrical water bag, workers often have to move around the water bag to clean the surface of the water bag. Cleaning is very inconvenient and the cleaning effect is not good. The concrete remaining on the surface of the water bag will reduce the service life of the water bag after solidification. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this application is to provide an underground continuous wall joint water bag sealing structure, which is used to solve the technical problems in the existing technology that the water bag needs to be manually cleaned during the lifting process, the cleaning is not thorough and inconvenient, and the concrete remaining on the surface of the water bag will reduce the service life of the water bag after solidification.
[0006] The above object of the present application is achieved through the following technical solutions: An underground diaphragm wall joint water bag plugging structure includes a cleaning device. The cleaning device includes a base, which is arranged above the outlet of the water bag. A circular through-hole is opened on the base, and the circular through-hole is communicated with the outlet of the water bag. A cleaning ring is installed on the base, and the cleaning ring is coaxial with the circular through-hole on the base. A telescopic device is arranged inside the cleaning ring, and a cleaning nozzle is arranged on the telescopic device.
[0007] By adopting the above technical solution, after the concrete in the steel cage solidifies, before lifting the water bag, the cleaning device needs to be installed above the installation opening of the water bag. When the water bag is lifted, the water bag is placed in the middle of the telescopic device. Start the water pump, and the cleaning nozzle cleans the water bag. It changes from manual cleaning to automatic cleaning. The cleaning nozzle installed on the telescopic device can clean the surface of the water bag in all directions, with thorough cleaning and high cleaning efficiency, which can ensure the service life of the water bag.
[0008] A further optimized solution is that the telescopic structure includes a telescopic spring, which is fixedly installed on the inner wall of the cleaning ring and is perpendicular to the inner wall of the cleaning ring. The other end of the telescopic spring is fixedly installed with a telescopic plate, and a cleaning nozzle is installed on the telescopic plate.
[0009] By adopting the above technical solution, since the water bag is in a lifted state, the radius of the water bag gradually increases from top to bottom. When the water bag passes through the cleaning device and is lifted out, the telescopic plate can abut against the surface of the water bag. During the process of lifting out the water bag, the continuously increasing outer surface of the water bag will squeeze the telescopic plate. At the same time, the rebounding force of the telescopic spring can keep the telescopic plate in contact with the outer surface of the water bag. At the same time, the telescopic plate can initially scrape the concrete slurry on the outer surface of the water bag, thus ensuring the cleaning effect.
[0010] A further optimized solution is that a high-pressure water pipe is connected to the cleaning nozzle, the other end of the high-pressure water pipe is connected to a high-pressure water pump, and the other end of the high-pressure water pump is connected to a water storage tank.
[0011] By adopting the above technical solution, the high-pressure water pump provides cleaning water for the cleaning nozzle.
[0012] A further optimized solution is that multiple telescopic devices are provided.
[0013] By adopting the above technical solution, multiple telescopic devices and multiple cleaning nozzles installed on the telescopic devices clean the surface of the water bag at the same time, increasing the cleaning efficiency and ensuring the cleaning effect.
[0014] A further optimized solution is that multiple said telescopic devices are distributed in a spiral shape.
[0015] For a further optimized solution, a protective layer is fixedly installed at the lower end of each telescopic plate, and the protective layer is a rubber layer.
[0016] By adopting the above technical solution, multiple telescopic devices are distributed in a spiral shape, and a protective layer is installed at the lower end of each telescopic plate, which can ensure that adjacent protective layers do not affect each other.
[0017] For a further optimized solution, the base, the cleaning ring, the telescopic spring and the telescopic plate are all made of stainless steel material.
[0018] By adopting the above technical solution, the stainless steel material can effectively avoid the corrosion of the base, the cleaning ring, the telescopic spring and the telescopic plate, and delay the service life of the cleaning device.
[0019] For a further optimized solution, a handle is installed on the base.
[0020] By adopting the above technical solution, it is convenient for the transportation and handling of the cleaning device.
[0021] For a further optimized solution, through holes are formed in the base, and pins are installed in the through holes.
[0022] By adopting the above technical solution, the base is fixed to the bottom surface using pins, which increases the stability of the cleaning device during operation.
[0023] In summary, the present application at least includes the following beneficial technical effects:
[0024] 1. When the concrete in the steel reinforcement cage solidifies, before lifting the water bag, the cleaning device needs to be installed above the water bag installation port. When the water bag is lifted, the water bag is placed in the middle of the telescopic device. The water pump is started, and the cleaning nozzle sprays water on the water bag for cleaning. The manual cleaning is changed to automatic cleaning. The cleaning nozzles installed on the telescopic device can clean the surface of the water bag in all directions, with thorough cleaning and high cleaning efficiency, which can ensure the service life of the water bag.
[0025] 2. By setting the telescopic spring and the telescopic plate, since the water bag is in a state of being lifted out, the radius of the water bag gradually increases from top to bottom. When the water bag passes through the cleaning device and is lifted out, the telescopic plate can abut against the surface of the water bag. During the lifting process of the water bag, the continuously increasing outer surface of the water bag will squeeze the telescopic plate. At the same time, the rebounding force of the telescopic spring can keep the telescopic plate in contact with the outer surface of the water bag. At the same time, the telescopic plate can initially scrape the concrete slurry on the outer surface of the water bag, thereby ensuring the cleaning effect.
[0026] 3. By setting multiple telescopic devices and multiple cleaning nozzles installed on the telescopic devices, the multiple cleaning nozzles simultaneously clean the surface of the water bag, increasing the cleaning efficiency while ensuring the cleaning effect.

Detailed implementation manners
[0030] The following further elaborates on the present application with reference to the accompanying drawings.
[0031] Embodiment, referring to Figure 1 and Figure 2 , an underground diaphragm wall joint water bag plugging structure, including a cleaning device. The cleaning device includes a base 1, the base 1 is arranged above the outlet of the water bag, a circular through hole is opened on the base 1, the circular through hole is communicated with the outlet of the water bag, a cleaning ring 2 is installed on the base 1, the cleaning ring 2 is coaxial with the circular through hole on the base 1, a telescopic device 3 is arranged inside the cleaning ring 2, a cleaning nozzle 4 is arranged on the telescopic device 3, a high-pressure water pipe 5 is connected to the cleaning nozzle 4, the other end of the high-pressure water pipe 5 is connected to a high-pressure water pump 6, and the other end of the high-pressure water pump 6 is connected to a water storage tank 7. After the concrete in the steel cage solidifies, before lifting the water bag, the cleaning device needs to be installed above the water bag installation opening. When the water bag is lifted, the water bag is placed in the middle of the telescopic device 3. Start the water pump, and the cleaning nozzle 4 cleans the water bag. It changes from manual cleaning to automatic cleaning. The cleaning nozzle 4 installed on the telescopic device 3 can clean the surface of the water bag in all directions, with thorough cleaning and high cleaning efficiency, which can ensure the service life of the water bag.
[0032] In the embodiment of the present disclosure, the telescopic structure includes a telescopic spring 30. The telescopic spring 30 is fixedly installed on the inner wall of the cleaning ring 2 and is perpendicular to the inner wall of the cleaning ring 2. The other end of the telescopic spring 30 is fixedly installed with a telescopic plate 31, and a cleaning nozzle 4 is installed on the telescopic plate 31. Since the water bag is in a state of being lifted out, the radius of the water bag gradually increases from top to bottom. When the water bag passes through the cleaning device and is lifted out, the telescopic plate 31 can abut against the surface of the water bag. During the lifting process of the water bag, the continuously increasing outer surface of the water bag will squeeze the telescopic plate 31. At the same time, the rebounding force of the telescopic spring 30 can keep the telescopic plate 31 in contact with the outer surface of the water bag. At the same time, the telescopic plate 31 can initially scrape the concrete slurry on the outer surface of the water bag, thereby ensuring the cleaning effect.
[0033] In order to increase the cleaning efficiency and ensure the cleaning effect, in the embodiments of the present disclosure, a plurality of telescopic devices 3 are provided, and cleaning nozzles 4 are installed on the telescopic plates 31 of each telescopic device 3. The plurality of cleaning nozzles 4 simultaneously clean the circumferential outer surface of the water bag, which can increase the cleaning efficiency while ensuring the cleaning effect.
[0034] Specifically, the plurality of telescopic plates 31 are spirally distributed, and a protective layer 32 is fixedly installed at the lower end of each telescopic plate 31. When hoisting the water bag, the plurality of telescopic plates 31 abut against the surface of the water bag, and the plurality of telescopic plates 31 abut against the surface of the water bag in a spiral shape, and protective layers 32 are fixedly installed at the upper and lower ends of each telescopic plate 31. Each protective layer 32 is in an arc shape. In this way, when the telescopic plate 31 is compressed, the protective layer 32 can effectively ensure contact with the surface of the water bag and can pre-scrape the concrete slurry on the surface of the hoisted water bag.
[0035] Specifically, the telescopic protective layer 32 is a rubber layer. When scraping the concrete slurry on the surface of the water bag, the rubber layer can prevent scratches on the surface of the water bag, thereby affecting the service life of the water bag. And the rubber layer has elasticity and can fit well with the surface of the water bag, increasing the efficiency of scraping the concrete slurry on the surface of the water bag.

[0037] In the embodiments of the present disclosure, in order to facilitate the transportation and handling of the cleaning device, a handle 8 is installed on the base 1.
[0038] In the embodiments of the present disclosure, in order to increase the stability of the cleaning device during operation. A through hole 10 is provided on the base 1, and a pin 11 is installed in the through hole 10 to fix the base 1 and the ground using the pin 11.
[0039] In the specific implementation process, before the water bag is hoisted out, the cleaning device is installed above the installation opening of the water bag, the cleaning device and the ground are fixed using the pin 11, then the high-pressure water pipe 5 is connected to the cleaning nozzle 4, and then when the water bag passes through the cleaning device, the high-pressure water pump 6 is started. While the water bag is being hoisted out, the cleaning nozzle 4 cleans the circumferential surface of the water bag. After the cleaning is completed, the high-pressure water pipe 5 is disassembled and assembled, the pin 11 is pulled out, and the cleaning device is moved to the storage area.
[0040] The embodiments of the present specific implementation manners are all preferred embodiments of the present application, and do not limit the protection scope of the application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
