Description

Technical Field

[0001] This utility model relates to the field of grouting pipeline cleaning technology, and in particular to a grouting fluid pipeline transportation and launching device. Background Technology

[0002] During tunnel boring machine (TBM) excavation, gaps appear between the tunnel segments and the soil as the TBM advances, requiring simultaneous grouting to fill these gaps. Simultaneous grouting involves a mixture of liquid A and liquid B, which are cement slurry and water glass, respectively. To ensure a continuous supply of liquid A during excavation, it is pumped via pipeline. However, as the pipeline extends further, the cement component in the liquid A tends to adhere to the pipe walls, potentially causing blockages over time. This not only hinders TBM progress but also necessitates significant manpower and resources for subsequent pipeline cleaning.

[0003] In existing technologies, pipe cleaning balls are used to clean pipes, but filling and recycling these balls is inconvenient and affects the efficiency of synchronous grouting in tunnel boring machines. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a grouting fluid pipeline transportation and launching device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A grouting fluid pipeline transportation and launching device includes a grouting pipeline and a flow meter. The inlet end of the grouting pipeline is connected to a vertical pipe. A connecting flange corresponding to the flow meter is provided on one side of the upper part of the vertical pipe. A ball valve is provided at the top of the vertical pipe. A launching port is provided at the top of the ball valve. A sealing cap is provided on the launching port. A recovery device is provided at the outlet end of the grouting pipeline. The recovery device includes an interception net, an inspection cover, and a spherical shell. A slag discharge valve is connected to the lower side of the spherical shell. The interception net is set at the grouting outlet of the spherical shell.

[0007] Preferably, one side of the flow meter is connected to a delivery pump, and the flow meter is connected to the upper part of the thick pipe.

[0008] Preferably, one end of the grouting pipe is connected to the lower end of the thin pipe, and the other end of the grouting pipe is connected to the spherical shell.

[0010] Preferably, the tamping rod is vertically disposed in the middle of the inner side of the spherical shell, and the lower end of the tamping rod extends to above the slag discharge valve.

[0011] The beneficial effects of this utility model are as follows: Compared with the prior art, this utility model sets a vertical pipe at one end of the grouting pipe as a ball launching device, and sets up a ball valve and a sealing cap for double sealing protection. It can quickly fill the pipe cleaning ball, pump cement slurry through a delivery pump, squeeze the pipe cleaning ball, and efficiently clean the pipe deposits, ensuring the cement slurry delivery efficiency.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0015] Reference Figure 1-2 A grouting fluid pipeline transportation ball launching device includes a pipeline cleaning ball, a grouting pipeline 5 and a flow meter 3. The pipeline cleaning ball is pushed by external force, such as compressed air, liquid pressure or mechanical traction, to move in the grouting pipeline 5 and clean the deposits in the pipeline. The pipeline cleaning ball is usually made of corrosion-resistant and highly elastic material. One side of the flow meter 3 is connected to a delivery pump, which is connected to an A liquid storage tank for pumping A liquid, i.e. cement slurry. The inlet end of the grouting pipe 5 is connected to a vertically installed vertical pipe 4. The vertical pipe 4 includes a thick pipe 41 and a thin pipe 42. The thick pipe 41 is located on the upper side of the thin pipe 42. The thin pipe 42 has the same diameter as the grouting pipe 5. The inner diameter of the thick pipe 41 is larger than the inner diameter of the thin pipe 42. The diameter of the pipe cleaning ball is between the inner diameter of the thick pipe 41 and the inner diameter of the thin pipe 42. The pipe cleaning ball is clearance-fitted with the thick pipe 41 and interference-fitted with the thin pipe 42. A connecting flange corresponding to the flow meter 3 is provided on one side of the upper part of the vertical pipe 4. The flow meter 3 is connected to the upper part of the thick pipe 41 through the connecting flange. A ball valve 2 is provided at the top of the vertical pipe 4. The inner diameter of the ball valve 2 channel is equal to the inner diameter of the thick pipe 41 to facilitate the passage of the pipe cleaning ball. A ball launching port is provided at the top of the ball valve 2 for inserting the pipe cleaning ball. When the delivery pump works, the pipe cleaning ball is launched with the help of liquid pressure. During the advance of the pipeline, the sediment in the pipeline is cleaned. A sealing cover 1 is provided on the launching port. A cavity is reserved between the sealing cover 1 and the ball valve 2 for temporarily storing the pipe cleaning ball. The sealing cover 1 combined with the ball valve 2 provides double protection to prevent cement slurry from overflowing. A recovery device 6 is provided at the outlet end of the grouting pipe 5 for recovering the pipe cleaning ball. The recovery device 6 includes an interception net 62, an inspection cover 63, and a spherical shell 64. One end of the grouting pipe 5 is connected to the lower end of the thin pipe 42, and the other end of the grouting pipe 5 is connected to the spherical shell 64 to realize the flow of cement slurry. The interception net 62 is set at the grouting outlet of the spherical shell 64. A slag discharge valve 7 is connected to the lower side of the spherical shell 64. The slag discharge valve 7 is used to discharge sediment fragments and mud, and at the same time recover the pipe cleaning ball. The inspection cover 63 is detachably mounted on the upper side of the spherical shell 64. The inspection cover 63 is equipped with a quick-release cover 61. A tamping rod 65 is mounted on the lower side of the quick-release cover 61. The tamping rod 65 is vertically mounted in the middle of the inner side of the spherical shell 64. The lower end of the tamping rod 65 extends to the top of the slag discharge valve 7. The intercepting net 62 and the tamping rod 65 are used to intercept the cleaned sediment and pipeline cleaning balls. At the same time, the tamping rod 65 can be used to clean the sediment and debris accumulated inside the spherical shell 64.

[0016] In this embodiment, after the grouting pipe 5 has been working for a period of time, it is cleaned regularly. The delivery pump is turned off or its power is reduced to decrease the cement slurry flow. The sealing cap 1 is opened, and a pipe cleaning ball is inserted into the launching port. The sealing cap 1 is closed, and the ball valve 2 is opened. The pipe cleaning ball passes through the ball valve 2 and falls into the coarse pipe 41, blocking the thin pipe 42. The ball valve 2 is closed, and the delivery pump pumps cement slurry to squeeze the pipe cleaning ball into the thin pipe 42. With the help of liquid pressure, the pipe cleaning ball is launched. As the cleaning ball moves forward in the pipeline, it cleans the deposits in the pipeline. The intercepting net 62 and the tamping rod 65 block the outlet end of the grouting pipe 5, preventing large particles of sediment and pipe cleaning balls from passing through. A recovery pipe is connected to the lower side of the slag discharge valve 7, or a mud container is placed to recover the sediment and pipe cleaning balls, avoiding environmental pollution and increased cleaning costs. The slag discharge valve 7 is opened to discharge the sediment, and the tamping rod 65 is used to assist in cleaning the mud and recovering the pipe cleaning balls. After cleaning is completed, the slag discharge valve 7 is closed, the normal power of the delivery pump is restored, and grouting continues.
