Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more schemes or examples.

[0021] like Figures 1 to 3 As shown, an embodiment of the present invention proposes a slipform device for channel construction, which includes: a slipform-formed steel sleeve body 1 and a piston shield body 2; the piston shield body 2 is installed in the slipform-formed steel sleeve body 1, and the slipform-formed steel sleeve body 1 is used for channel slipform construction. In actual use, by abutting the cutter disc body on the channel slipform with the piston shield body 2, the cutter disc body on the channel slipform will be guided to move along with the movement of the piston shield body 2, thereby greatly improving the service life of the equipment. At the same time, its guided movement will also achieve precise guidance and controllability in the reception work of the channel slipform, which is beneficial to the speed of receiving the channel slipform.

[0022] In this embodiment, the piston shield 2 comprises a front cover plate 21, a rear cover plate 22, and a support cylinder 23. The front cover plate 21 is mounted on the rear cover plate 22 and forms a cylindrical body with two open ends. The support cylinder 23 is mounted on the surface of the rear cover plate 22 at least once, and the output shaft of the support cylinder 23 can abut against the inner wall of the slip-formed steel sleeve body 1. In practice, this design ensures that the piston shield 2 is easily replaceable, significantly extending the service life of the entire device. Furthermore, the smooth periphery facilitates the sliding of the piston shield 2 within the slip-formed steel sleeve body 1. The support cylinder 23 also provides a buffer, reducing impact on the piston shield 2.

[0023] In this embodiment, the slipformed steel sleeve body 1 is further provided with a track 11 and a spring steel brush 12. The spring steel brush 12 is mounted above the inner wall of the slipformed steel sleeve body 1 and is engageable with the piston shield 2. The track 11 is disposed within the slipformed steel sleeve body 1 and is in sliding engagement with the piston shield 2. In practice, the spring steel brush 12 serves the purpose of scrubbing the surface of the piston shield 2 to reduce sediment interference. Furthermore, the track 11 ensures the orderly sliding of the piston shield 2, thereby ensuring the proper reception and guidance of the channel slipform.

[0024] In this embodiment, the slip-formed steel sleeve body 1 is also equipped with a spring steel plate sealing brush 13; this spring steel plate sealing brush 13 is mounted at the front end of the slip-formed steel sleeve body 1 and is detachably connected to the slip-formed steel sleeve body 1 using bolts. In actual design, this design provides preliminary cleaning and filtration of dirt and other substances in the piston shield body 2, thereby extending the actual service life of the equipment.

[0025] In this embodiment, a lubrication mechanism 3 is further included; the lubrication mechanism 3 includes a grease injection line 31 and a grease line 32. The grease injection line 31 and the grease line 32 are both disposed between the spring steel brushes 12 for lubricating the spring steel brushes 12. In practice, this design improves the lubrication between the spring steel brushes 12.

[0026] In this embodiment, a pre-embedded steel ring 4 is also included, which is arranged in the excavation direction of the outer forming sleeve and can abut against the spring steel plate sealing brush 13. In actual use, this mechanism is for guidance, facilitating the positioning and alignment of the above-mentioned other devices and the channel sliding mold.

[0027] In this embodiment, the slip-formed steel sleeve body 1 is further provided with multiple positioning pins 14, which are located at the sleeve opening and extend forward for insertion into pre-reserved holes 100 in the embedded wall. In practical applications, this design ensures the slip-formed steel sleeve body 1 is securely fixed and further enhances the guiding effect.

[0028] In this embodiment, the slipformed steel sleeve body 1 is assembled from at least one section of steel sleeve 10. In actual use, the split design adopted can splice slipformed steel sleeve bodies 1 of different lengths according to the size and length of the channel slipform, greatly expanding the scope of application.

[0029] In this embodiment, a buffer cylinder 5 is further included, which is disposed within the steel sleeve 10 and is located away from the embedded steel ring 4. In actual use, this design complements the support cylinder 23 described above, achieving secondary buffer support and further extending the actual service life of the piston shield 2.

[0030] In this embodiment, a support assembly 6 is further included, and the support assembly 6 includes a support column 61, and the support column 61 is used to support the steel sleeve 10. In actual use, the support column 61 is used to fix the entire device.

[0031] In actual work, the piston shield body 2 is first compressed into the interior of the slipformed steel sleeve body 1, and then the mortar is injected into the slipformed steel sleeve body 1; then the channel slipform is started to abut against the mortar, and the mortar is continuously cut. In this way, the piston shield body 2 behind the mortar will be effectively retreated under the guidance of the guide rail, thereby guiding the channel slipform and facilitating the acceptance of the channel slipform.
