Description

Technical Field

[0001] The utility model belongs to the technical field of hole-forming devices, and in particular relates to a hole-forming device for prefabricated beam prestressed channels. Background Art

[0002] The extraction rods used in high-speed rail prefabricated beams are relatively heavy and stored in a messy manner on site. Professional extraction teams and equipment must be hired when inserting them. The extraction rods themselves cannot expand. If they are pulled out too early, the concrete will fall off due to unsolidification, causing the channel to become smaller or partially blocked. If they are pulled out too late, the pressure of the concrete itself will make it difficult to pull out the extraction rods, or even impossible to pull them out. Since the intelligent telescopic extraction tube can be easily pulled out by the principle of its own expansion, a prefabricated beam prestressed channel hole-making device is proposed.

[0003] For example, a Chinese patent with publication number CN218928138U discloses a prestressed hole forming device and a prefabricated T-beam, wherein the prestressed hole forming device comprises a pull-out piece, which is arranged in a mold of the prefabricated T-beam through positioning steel bars, and the pull-out piece is a flexible hollow pipe with steel strands arranged inside. There are multiple positioning steel bars, which are arranged at intervals along the length direction of the prefabricated T-beam to fix the installation position of the pull-out piece, and the pull-out piece is made of rubber material.

[0004] The existing technical documents have the following problems:

[0005] The existing technical documents have some shortcomings when used, such as: after inflation, due to the vibration of the vibrating rod or the pressure of concrete, the hose will leak in serious places, and the pressure relief will cause the hole to be blocked, resulting in the inability to find the hose leak in the first time, thereby reducing the success rate of construction, and the plastic corrugated pipe or metal corrugated pipe cannot be coiled during transportation, and occupies a large space, so it occupies a large space during transportation. In view of this, we propose a prefabricated beam prestressed hole forming device. Utility Model Content

[0006] The purpose of the utility model is to provide a prefabricated beam prestressed channel hole forming device to solve the above-mentioned technical problems, so as to achieve the effect of timely detecting hose leakage and conveniently remedying the hose.

[0007] In view of this, the utility model provides a prefabricated beam prestressed channel hole forming device, including a pipe body, and also including: the inner wall of the pipe body is fixedly provided with a secondary pressurization layer of the pipe body, the inner wall of the secondary pressurization layer of the pipe body is fixedly provided with an outer rubber layer of the pipe body, the inner wall of the outer rubber layer of the pipe body is fixedly provided with a second pressurization layer of the pipe body, the inner wall of the second pressurization layer of the pipe body is fixedly provided with a first pressurization layer of the pipe body, the inner wall of the first pressurization layer of the pipe body is fixedly provided with an inner rubber layer of the pipe body, the outer rubber layer of the pipe body and the inner rubber layer of the pipe body are made of natural synthetic rubber, one side of the pipe body is sleeved with a socket, one side of the interior of the socket is penetrated and installed with an external threaded seat, one side of the external threaded seat is penetrated and installed with an air stop valve, the other side of the external threaded seat is fixedly installed with an air bag, a connecting pipe is penetrated and installed on one side of the air stop valve, a pressure gauge is fixedly installed on the top of the connecting pipe, a gas filling pipe is penetrated and installed on one side of the connecting pipe, and a sealing seat is fixedly installed on the other side of the pipe body.

[0008] Based on the above structure, through the coordinated use of the air filling pipe, the air bag and the pressure gauge, during the construction, if the pipe body is found to be leaking, the leakage can be discovered in time through the changes in the pressure gauge, and the internal air bag can be inflated to support the external pipe body to achieve the purpose of hole formation. Because there is an internal air bag as secondary protection, the hole formation rate of this product can be said to be 100%, and it can be recycled for more than 200 times, which greatly saves costs and stops working. The pipe body can be folded and coiled during transportation, thereby reducing the space volume occupied by the pipe body during transportation and facilitating transportation.

[0009] Preferably, a tube core is fixedly provided on the inner wall of the rubber layer in the tube body. The tube core is made of rubber material, and the tube core is utilized to enhance the flexibility and pressure resistance of the pipeline.

[0010] Preferably, a valve is sleeved on the surface of the gas filling pipe, the valve is made of stainless steel, and the opening and closing of the gas filling pipe is controlled by the valve.

The pressure gauge is convenient for detecting the pressure change in the pipe. The internal pressure of the pipe determines the external diameter of the pipe. Therefore, the external size of this product is determined by the internal air pressure, so as to meet the designed hole size. Then, the connecting pipe is conveniently disassembled and installed through the air stop valve, and then the air bag is conveniently inflated through the air filling pipe. Through the coordinated use of the air filling pipe, the air bag and the pressure gauge, if a leak is found during construction, During work, it can detect air leakage in time through the changes in the barometer and stop working, thereby improving the success rate of construction. Compared with the corrugated pipes and rubber extraction rods currently used, the pipe body can save more than 40% in material costs alone and can be reused more than 100 times. The replaced intelligent telescopic pulling pipe can also be deflowed to prepare rubber powder and then made into other rubber products, which can promote the recycling of resources and greatly improve the economic benefits.
