Description

Technical Field

[0001] The utility model relates to the technical field of pre-pressurized water bags, in particular to a pre-pressurized water bag air-lift drainage bag. Background Art

[0002] Pre-pressure water bag is also known as test pressure water bag or pre-pressure water bag. Its products are widely used in the construction of railway and highway bridges, airport terminals. During the bridge construction phase, pre-pressure testing of bridge load is a key task in the inspection of engineering quality compliance. The traditional method is to pile up iron cans or sandbags on the bridge for actual pressure testing. It takes a lot of manpower and material resources to move a large number of these load-bearing items from a low place to the bridge.

[0003] During the construction of roadbed preloading water bags, due to roadbed filling materials, half-cut and half-filled roadbed treatment, mechanical equipment and construction technology, environmental factors and special geological conditions, after the water bag preloading is completed, the preloading ground will be uneven and bumpy, which will easily affect the quality and life of the water bag and leak after being punctured. When the preloading is unloaded, there will be a part of residual water in the water bag, which makes it difficult to discharge the residual water. It needs to be manually drained through a series of methods such as moving, lifting, and squeezing, which increases physical labor and labor consumption, seriously affects the unloading and exit time, and affects the construction progress. Utility Model Content

[0004] In view of the deficiencies of the existing technology in the above-mentioned background technology, the purpose of the utility model is to provide a pre-pressurized water bag air lift drainage bag to prevent water leakage when the pre-pressurized water bag receives water, and to quickly drain water during pre-pressurization unloading, thereby saving manpower, improving efficiency, and shortening the unloading and exit time.

[0005] Compared with the prior art, the technical solution of the utility model is:

[0006] A pre-pressurized water bag air lift drainage bag comprises a drainage air bag body, one side of the drainage air bag body is connected to an air inlet pipe, a one-way valve is fixedly installed on the air inlet pipe, a water bag body is arranged on the drainage air bag body, the top of the water bag body is connected to a water inlet, a water inlet pipe is threadedly connected to the water inlet, and a locking ring is sleeved at the connection between the water inlet and the water inlet pipe.

[0007] As a further solution of the utility model, a mounting seat is installed inside the water inlet, and two groups of the mounting seats are symmetrically arranged along the central axis of the water inlet. A fixing frame is fixedly installed between the two groups of the mounting seats, and a filter is fixed on the fixing frame.

[0008] As a further solution of the present invention, the locking ring includes a locking ring body and a locking washer, the locking washer is fixedly mounted on the locking ring body, and the locking ring body and the locking washer are integrally formed.

[0009] As a further solution of the utility model, a threaded opening is provided on the locking gasket.

[0010] As a further solution of the utility model, limited guardrails are fixed on both sides of the drainage airbag body.

[0011] As a further solution of the utility model, one side of the water bag body is connected to a drain pipe.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] (1) The utility model has a drainage airbag body, and there are limit guardrails on both sides of the drainage airbag body to prevent the drainage airbag body from rolling. One side of the drainage airbag body is connected to an air inlet pipe, and a one-way valve is fixedly installed on the air inlet pipe. Before the construction of the pre-pressurized water bag, the drainage airbag body is first flattened and laid, and the water bag body is installed on the drainage airbag body. Such an arrangement can prevent the water bag body from being damaged, protect the water bag body, and extend the service life of the water bag body. At the end of the pre-pressurization period, the one-way valve is opened to allow the air inlet pipe to inflate the drainage airbag body. The one-way valve is provided to prevent the gas from escaping, thereby raising the height of one side of the water bag body. When the pre-pressurization is unloaded, the water can be quickly drained, so that no part of the water will remain in the water bag body, saving manpower, improving efficiency, and shortening the unloading and exit time.

[0014] (2) The utility model ensures the sealing performance between the water inlet pipe and the water inlet through the cooperation between the locking ring body and the locking gasket, and can also ensure the tightness between the water inlet pipe and the water inlet.

[0015] (3) The utility model uses a fixing frame fixedly installed between the mounting seats to install the filter screen inside the fixing frame, and uses the filter screen to filter out large particles in the water to prevent sand and gravel from accumulating in the water bag.
