The utility model discloses the structure, simple to operate with the connection that grid base can be very convenient in row mud device below, it is little to occupy space, does not need very complicated structural support and fixes. The cross-shaped spray head can complete vertical striking and lateral striking, massive cement fragments possibly occurring in the tubular pile can be struck in multiple directions, the striking effect is improved, and the blocking condition in the use process of equipment in the tubular pile is effectively avoided. The cross spray head is firm and durable, the effect of cleaning the broken high-hardness deposition layer in the pipe pile is obvious, the cross spray head can be well combined with sludge discharge cleaning equipment, and the breaking and cleaning work of the high-hardness deposition layer in the pipe pile is effectively solved.
