[0002] The underground continuous wall is a structure widely used in the field of construction. The rubber waterstop joint box is a device for fixing the rubber waterstop to achieve better construction effect of the underground continuous wall. During the use of the rubber waterstop joint box, it is found that there is a weak part on the concrete wall after the construction is completed and the joint box is removed. The concrete at this part is extremely easy to fall off due to the too thin thickness. This not only destroys the aesthetics of the underground continuous wall, but also has a certain influence on the construction quality. Figure 1 As shown in the figure, it is a top view of the rubber waterstop joint box currently in use. The shaded part in the figure is the pouring position of the concrete, and the areas A and B in the figure are the weak parts of the concrete wall. Figure 1 In the prior art, a bevel design exists at the bottom of the joint box for the convenience of demolding, and the concrete at this part is more prone to damage and needs to be filled later. Therefore, a device needs to be designed to solve this problem. SUMMARY

[0019] The specific embodiments of the present application are described in further detail below with reference to the accompanying drawings. The accompanying drawings are used to illustrate the present application, but are not used to limit the scope of the present application.

[0020] As shown in Figure 2 A rubber waterstop joint box bladder device 20 of the present application is divided into two parts, ground and underground. The underground part includes a box and a bladder, and the ground part includes a water pump and a flow control valve. The underground part is arranged on both sides of the joint box. The box is a closed structure as a whole, and has only one cavity in which the bladder is placed. The water pump and the flow control valve are installed outside the box and connected to the underground part through pipelines.

[0021] As shown in Figure 3 A rubber waterstop joint box bladder device of the present application includes a box 1, a bladder 2, a flow control valve 3, a water pump 4 and other auxiliary components.

[0022] The box 1 is a metal welded box placed on both sides of the joint box. It has a cavity inside, and the two steel plates on the outside have a plurality of long round holes through which the bladder 2 can be ejected from the box 1. The steel plate on the top surface of the box has two round holes through which the pipeline passes to connect the ground and underground parts. The box 1 can make the concrete wall have an aesthetic appearance and a regular structure, and prevent the concrete wall from having a thin wall. At the same time, it also avoids the direct contact between the bladder 2 and the concrete wall, to a certain extent, to protect the bladder.

[0023] Specifically, the box 1 is a metal welded part, and the box 1 is welded by six steel plates. The top plate 11 has two round holes as water inlet and outlet channels of the bladder 2. One of the round holes is used as a water inlet channel and connected to the flow control valve 3, and the other round hole is used as a water outlet channel and connected to the water pump 4. The side plate 12 and the side plate 13 have uniformly distributed through holes arranged in a linear arrangement, and the through holes are long round holes.

[0024] The material of the bladder 2 is rubber and fiber cloth, which needs to ensure its sealing property. The size of the bladder 2 should be as large as possible to fill the cavity of the box, and must cover the long round holes on the two steel plates in the box.

[0025] The water pump is a component structure, which can pump water from a low place to a high place. The water pump is connected to the bladder through a pipeline, and the specification of the pipeline is determined by the depth of the underground continuous wall.

[0026] The flow control valve is arranged on another pipeline connected to the bladder 2, which can control the speed of water input into the bladder 2.

[0027] When the bladder device and the joint box are placed in the ground wall groove section, the large surface of the box 1 is in contact with the side wall of the joint box, and the small surface is in contact with the concrete to be poured. Water is sent into the bladder 2 through the water inlet channel, and the flow rate of water is controlled by the flow control valve 3 until the bladder 2 is slightly full.Figure 4 As the long hole on the box 1 is basically covered by the bladder 2, the external concrete slurry cannot enter the box 1 in large quantities.

[0028] When the external concrete wall is formed, water continues to be sent into the bladder 2 from the water delivery channel until the bladder 2 is in a fully filled state, as shown in Figure 5 The bladder 2 is fully filled and pushes out the long hole at the facet, pushing the concrete wall, so that the box 1 is separated from the concrete wall.

[0029] Then the water pump 4 is started to pump out the water in the bladder 2 from the water pumping channel, so that the bladder 2 is retracted into the box 1, preventing the bladder 2 from being damaged when the bladder lifting device is lifted. After pumping, the bladder device is lifted out of the ground wall slot section.

[0030] In addition, when the device is removed, the water pump 4 is adjusted to cycle the water inlet and outlet action back and forth, so that the bladder 2 is in a cycle of expansion and contraction. The bladder 2 can repeatedly stretch and contract at the opening, thereby assisting the separation of the box 1 and the concrete and the joint box.
