Description
Technical field
The present invention relates to engineering machinery field, a kind of particularly push-bench drill bit used in the jacking construction of rock stratum,
Or a kind of push-bench containing the drill bit.
Background technology
Rock stratum push-bench runs into that the loss of micro- weathered rock formation cutter head hard alloy is larger may to damage knife in drilling process
Head, the average factory that need to return push pipe machinery per 90 meters or so of jacking changes a cutter head, about 510,000 yuan of cutter head expense is changed every time, together
When, because single jacking distance is shorter, need to set multiple received wells in construction, to ensure that push-bench is smoothly appeared, so significantly
Increase construction period and construction cost.Often occur causing head to be stuck in hole because tool bit abrasion is excessive in construction, can only pass through
Heavy excavation manually exists to hanging out head to driving, causes construction delay, increases working measure expense.
In i.e. present city rock stratum jacking construction, the cutter head that conventional rock stratum push-bench is used has the disadvantage that：
1st, cutter head abrasion are big, and reduction cutter head cuts ability, and single jacking is apart from short.
2nd, cutter head abrasion are big, easily occur because cutting bit freezing in the not enough hole of power, because mechanical dimension is smaller, head without repairing storehouse,
Heavy excavation can only be carried out hang out head to be repaired.
3rd, single jacking distance is shorter, need to set substantial amounts of received well, active well, increase construction cost and construction period.
4th, cutter head is worn away greatly, is added up jacking apart from shorter, is returned factory and change cutter head frequency height, increase construction cost and construction work
Phase.
