Description
Technical field
The present invention relates to engineering machinery field, specifically annular pitch excision pressure paving all-in-one machine.
Background technique
There are the urban operating mechanisms inspection shafts such as many draining, electric power, water supply on urban road.Benefit, more is being repaired to well lid
It when changing, needs the bituminous pavement excision around well lid, existing excision is mechanical generally to carry out drip excision using cutting machine.
But cutting machine needs to rotate multi-turn and thicker bitumen layer could be cut to biography excision, efficiency is slow.And the joint-cutting of cutting machine is
Vertical joint-cutting, worker need to stick up the pitch of excision out using tools such as crowbars, have a joint-cutting very narrow, sometimes crowbar
Also it is difficult to stick up out, cutter can only be reused by edge and cut off a fritter, it so just can easily be by the annular pitch of excision
Subsequent lower shovel removes cleaning, entire pitch reset procedure inefficiency.
And well lid be installed after also need to dig out slot hole carried out filling and leading up covering with new pitch.Fill and lead up covering
Pitch also needs to be compacted just may be used.So small-scale asphalt compaction work is not suitable for large-scale compacting machinary, for example presses
Road machine.But it can be good at completing compacting task in the prior art either with or without a kind of machinery.So worker can only put template
Onto compacting pitch, template then is beaten with tup and carries out asphalt compaction, but compaction is far from enough, and generally presses
Pitch after reality keeps not concordant with road surface, pit or convex slope occurs, will appear vibration when vehicle crosses.
As stated above, there are many practical property in the excision of entire annular bituminous sheaths, pressure paving work, but not yet very
Good solution.
