Description

Technical Field

[0001] This utility model relates to the field of cutting fluid injection technology, specifically a multi-layer pressurized water ultra-deep TRD waterstop curtain cutting fluid injection device. Background Technology

[0002] In the construction of ultra-deep (e.g., depth greater than 50 meters) TRD waterstop curtains, the cutting box needs to traverse complex strata with varying permeability, such as sand layers, clay layers, etc., from top to bottom.

[0003] Currently, cutting fluid is usually injected into the cutting box during operation to prevent the tank wall from collapsing or the grout from surging. However, the cutting fluid currently injected is relatively simple. When used in gravel layers, its viscosity and wall protection ability may be insufficient, leading to tank wall collapse. When used in clay layers, its viscosity is too high, making it difficult to pump and diffuse, easily forming a "mud bag" phenomenon. Furthermore, the excessive flow resistance can cause abnormally high grouting pressure, leading to grout surging. Utility Model Content

[0004] The purpose of this invention is to provide a multi-layer pressurized water ultra-deep TRD waterstop curtain cutting fluid injection device to overcome the shortcomings of the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-layer pressurized ultra-deep TRD waterstop curtain cutting fluid injection device, comprising a housing, and further comprising: an injection channel fixedly connected to the top of the housing, with one end of the injection channel communicating with the inner cavity of the housing; multiple pipes arranged in a circumferential array and fixedly connected to the injection channel, with each injection channel having a sealing component; and a switching assembly comprising a rotating frame rotatably connected to the injection channel, a water-passing plate fixedly connected to the rotating frame, and a connecting pipe slidably connected to each pipe in turn.

[0006] Preferably, each of the pipes includes a first pump pipe connected to the injection channel and an inlet pipe communicating with the injection channel, and the first pump pipe and the corresponding inlet pipe are connected in an L-shape.

[0007] Preferably, each of the sealing components includes: a receiving tube, which is fixedly connected to the corresponding pipe, with one end being a closed end and the other end being an open end, the open end of the receiving tube communicating with the pipe; a sealing block, which is slidably connected inside the receiving tube; and a first spring, one end of which is fixedly connected to the closed end of the receiving tube and the other end of which is fixedly connected to the sealing block, and the process of the first spring restoring its elastic deformation drives the sealing block to seal the liquid inlet end of the inlet tube.

[0008] Preferably, each of the receiving tubes and the inlet tubes are coaxially and fixedly connected.

[0009] Preferably, the inlet end of each of the first pump tubes is connected to an external storage tank via a first hose, and each storage tank stores cutting fluid of different concentrations.

[0010] Preferably, a first motor is fixedly connected to the top of the housing, and the output shaft of the first motor is fixedly connected to the rotating frame.

[0011] Preferably, a first cylinder is fixedly connected to the rotating frame, the telescopic end of the first cylinder is fixedly connected to the connecting pipe, and a push rod that abuts against the corresponding sealing block is fixedly connected to the connecting pipe.

[0012] Preferably, the box is equipped with a drain pump, and the outlet end of the drain pump is connected to the injection channel of the cutting box through a liquid guiding hose.

[0013] In the above technical solution, this utility model provides a multi-layer pressurized water ultra-deep TRD waterstop curtain cutting fluid injection device. The type of cutting fluid injected varies depending on the geological formation. First, a first motor drives a rotating frame to rotate a water-passing plate until the connecting pipe aligns with the corresponding inlet pipe. Then, a first cylinder drives the connecting pipe to slide relative to the water-passing plate until the push rod abuts against the sealing block inside the corresponding inlet pipe. The telescopic end of the first cylinder then continues to move the sealing block, connecting the first pump pipe to the corresponding inlet pipe. Based on this, the cutting fluid can be injected into the tank from the corresponding external storage tank through the pump in the first pump pipe. In summary, this device can spray the cutting fluid from the corresponding storage tank into the cutting trench to prevent trench wall collapse or slurry overflow. Furthermore, different concentrations of cutting fluid can be sprayed according to different permeability of the geological formation to achieve better protective effects. Furthermore, when the first cylinder drives the push rod to retract, the elastic force of the first spring restoring its elastic deformation drives the sealing block to reset, thereby cutting off the connection between the first pump pipe and the corresponding inlet pipe. The entire process can achieve that the connecting pipe is only connected to one pipe, while other pipes are automatically sealed to prevent the mixing of cutting fluid of other concentrations.

Detailed Implementation

[0017] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0018] Please see Figure 1-5 This utility model provides a multi-layer pressurized ultra-deep TRD waterstop curtain cutting fluid injection device, including a housing 1, an injection channel 2, multiple pipes 3, and a switching component 5. The injection channel 2 is fixedly connected to the top of the housing 1, and one end of the injection channel 2 is connected to the inner cavity of the housing 1. The multiple pipes 3 are arranged in a circumferential array and fixedly connected to the injection channel 2, and each injection channel 2 is provided with a sealing component 4. The switching component 5 includes a rotating frame 51 rotatably connected to the injection channel 2, a water passage plate 52 is fixedly connected to the rotating frame 51, and a connecting pipe 53 that is slidably connected to each pipe 3.

[0019] Each pipe 3 includes a first pump pipe 31 connected to the injection channel 2 and an inlet pipe 32 connected to the injection channel 2, and the first pump pipe 31 and the corresponding inlet pipe 32 are connected in an L-shape.

[0020] Each sealing component 4 includes: a receiving tube 41, which is fixedly connected to the corresponding pipe 3, with one end being a closed end and the other end being an open end, the open end of the receiving tube 41 communicating with the pipe 3; a sealing block 42, which is slidably connected inside the receiving tube 41; and a first spring 43, one end of which is fixedly connected to the closed end of the receiving tube 41, and the other end of which is fixedly connected to the sealing block 42, and the process of the first spring 43 restoring its elastic deformation drives the sealing block 42 to seal the liquid inlet end of the inlet pipe 32. It should be noted that the sealing block 42 is cylindrical, and the length of the sealing block 42 in the circumferential direction is greater than the diameter of the first pump pipe 31, so that the sealing block 42 can simultaneously seal the inlet pipe 32 and the receiving tube 41, preventing the cutting fluid from flowing into the inlet pipe 32 and the receiving tube 41 under the sealed state.

[0021] Each receiving tube 41 is coaxially and fixedly connected to its corresponding inlet tube 32. It should be noted that the receiving tube 41 and the inlet tube 32 are made of the same type of pipe 3.

[0022] Each of the first pump pipes 31 has its inlet end connected to an external storage tank (not shown in the figure) via a first hose, and each storage tank stores cutting fluid of different concentrations.

[0023] The top of the housing 1 is fixedly connected to a first motor 9, and the output shaft of the first motor 9 is fixedly connected to the rotating frame 51.

[0024] The rotating frame 51 is fixedly connected to a first cylinder 6, the telescopic end of the first cylinder 6 is fixedly connected to a connecting pipe 53, and a push rod 7 that abuts against the corresponding sealing block 42 is fixedly connected to the connecting pipe 53. It should be noted that the water passage plate 52 has a through-hole for the rod of the first cylinder 6 to pass through.

[0025] The box 10 is equipped with a drain pump 8, and the outlet end of the drain pump 8 is connected to the injection channel of the cutting box 1 through a liquid guiding hose.

[0026] Specifically, the above workflow is as follows: when the cutting box is cutting the stratum, the cutting fluid in the external storage tank needs to be sprayed sequentially through the corresponding pipe 3, injection channel 2, tank body 1, and finally through the injection channel, so as to prevent the tank wall from collapsing or the slurry from surging up.

[0027] Based on this, the cutting fluid injected varies depending on the geological formation. Therefore, the first motor 9 drives the rotating frame 51 to rotate the water-passing plate 52 until the connecting pipe 53 aligns with the corresponding inlet pipe 32. Then, the first cylinder 6 drives the connecting pipe 53 to slide relative to the water-passing plate 52 until the push rod 7 abuts against the sealing block 42 inside the corresponding inlet pipe 32. Afterwards, the telescopic end of the first cylinder 6 continues to move the sealing block 42, connecting the first pump pipe 31 with the corresponding inlet pipe 32. Based on this, the cutting fluid can be injected from the corresponding external storage tank into the tank 1 via the pump in the first pump pipe 31. In summary, the cutting fluid from the corresponding storage tank can be sprayed into the cutting groove to prevent groove wall collapse or slurry overflow. Furthermore, different concentrations of cutting fluid can be sprayed according to different geological formations with varying permeability to achieve better protective effects. Furthermore, when the first cylinder 6 drives the push rod 7 to retract, the elastic force of the first spring 43 restoring its elastic deformation drives the sealing block 42 to reset, thereby cutting off the connection between the first pump pipe 31 and the corresponding inlet pipe 32. The entire process can achieve that the connecting pipe 53 is connected to only one pipe 3, while other pipes 3 are automatically sealed to prevent the mixing of cutting fluid of other concentrations.

[0028] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
