Technical Field

The invention relates to the field of hydraulic engineering, in particular to an underwater automatic chiseling device.

Background

The caisson is a deep foundation, is mainly used for wharfs, breakwaters and the like, is of a box-type structure, is internally provided with a partition plate, is filled with sand or rock blocks during construction, and is capped by a capping plate at the top to form a bearing and vertical wall structure of a main body. In areas with harsh environments, the caisson surface often falls off due to the effects of temperature, wave impact and the like, which affects the safety of wharfs or breakwaters, and therefore needs to be maintained. At present, underwater concrete pouring is also mature, but for repairing the caisson, the underwater maintenance mode is still low in efficiency, and one of the main reasons for the low underwater maintenance efficiency of the caisson is roughening treatment before concrete pouring.

Most of existing chiseling machines are used on land, even if a chiseling head can be used underwater, because of the wind and wave, existing mechanical equipment cannot be used underwater, and underwater operation must be performed manually, or a caisson is lifted out of the water surface to perform chiseling operation. No matter the operation is carried out underwater or lifted out of the water surface, the operation is very troublesome, the side surface of the caisson with the length of 10m × 2.6m is often constructed, when the scabbling depth is 0.04m, more than 6 hours are needed, time and labor are wasted, certain potential safety hazards exist in underwater construction, and the caisson is damaged secondarily due to the fact that the caisson is moved in the construction of lifting out of the water surface.

Therefore, an underwater roughening device is highly needed, which can safely and rapidly perform roughening treatment on the caisson and improve the working efficiency.
