Description

Technical Field

[0001] The utility model relates to the technical field of sea reclamation construction, in particular to a groove milling device. Background Art

[0002] With the progress of urbanization, the demand for urban land is increasing. Some cities increase urban land supply by reclaiming land from the sea, and many cities build airports on reclaimed land. Reclaimed land is usually soft marine clay. Under long-term immersion and scouring by seawater, the reclaimed land is easily liquefied, causing soil erosion and instability. Therefore, it is necessary to carry out foundation treatment on the reclaimed soft soil layer.

[0003] When the foundation treatment is carried out on the reclaimed stratum used for the airport, an underground continuous wall is usually constructed in the reclaimed stratum to reinforce the reclaimed stratum. In the construction of the underground continuous wall, a milling device is required to excavate the reclaimed stratum for the construction of the underground continuous wall. When the milling device is used to excavate the reclaimed stratum, it may be necessary to carry out the construction without stopping the flight. Therefore, there is a certain limit on the height of the milling device. The current milling device is relatively high and cannot meet the needs of non-stop construction. Utility Model Content

[0030] The technical solution of the utility model is that the mounting end of the support arm 21 is hinged to the mounting area, and then a telescopic arm 22 is arranged. The connecting end of the telescopic arm 22 is hinged to the mounting area, and the telescopic end of the telescopic arm 22 is hinged to the support arm 21. A guide pulley 43 is installed at the supporting end of the telescopic arm 22. One end of the traction rope 42 passes through the guide pulley 43 and is connected to the mounting seat 31. The other end of the traction rope 42 is connected to the traction member 41. By tightening or releasing the traction rope 42 by the traction member 41, the mounting seat 31 and the cutter 32 on the mounting seat 31 can be driven to rise or fall, thereby excavating the reclamation stratum. By extending or shortening the telescopic arm 22, the support arm 22 can be driven to rotate around the mounting end of the support arm 22, so that the supporting end of the support arm 22 rises or falls. When the slot milling device 100 of the utility model performs foundation treatment on the reclamation stratum used for the airport, it only needs to shorten the telescopic arm 22 to reduce the height of the supporting end, so that the height of the slot milling device 100 is reduced, thereby meeting the needs of non-stop construction.
