Description
Technical field
The present invention relates to the mechanical related more particularly to one kind of underground construction directly to pull out from precast hollow component hollow space
Out can undergauge bit.
Background technique
Pile foundation construction method is mainly by artificial digging pile at present, and Driven Piles, static pressed pile, cast-in-situ bored pile etc. are several, people
Work caisson low efficiency, construction personnel's degree of risk are high；Noise pollution is serious in Driven Piles work progress, strictly restricts its hair
Exhibition；Though static pressed pile has low noise, free of contamination feature, its soil compaction effect is obvious, and in cannot entering, macro scar so that
High-intensitive prefabricated pile bearing capacity is not fully played；Cast-in-situ bored pile uses mud off, and mud contamination is serious.One
Kind can undergauge bit and its construction method can effectively solve the above difficulty.
Summary of the invention
It is an object of the present invention to provide one kind can undergauge bit and its construction method.To solve the above problems, can undergauge bit
It constructs for precast hollow component, construction without squeezing soil not only may be implemented, but also can choose whether whitewashing liquid, dry powder or other reinforcings
Material etc. is reinforced to improve bearing capacity, can also be entered rock construction, be obtained the high bearing capacity of precast hollow component sufficiently
Play, reduce cost, can undergauge bit cutting construction, after pile sinking can undergauge extract, it is convenient to construct, high-efficient.
The present invention is realized by following technical approach:
One kind can undergauge bit and its construction method, the drill bit mainly includes six square joints, moving vane one, fulcrum spiral shell
Bolt, shaft, anchor ear, inserted pin special, moving vane two, spray orifice one, moving vane three, plate tooth, spray orifice two, spray orifice three, described six
Square joint is connect with drilling rod, moving vane one, moving vane two, and moving vane three is installed by pivot bolt and inserted pin special
On respective anchor ear, the plate tooth is mounted on moving vane three, and the spray orifice is arranged on shaft.
The drill bit is mainly used for the precast hollow component that internal diameter is greater than 400mm.
It can elbow-board tooth, pick on the moving vane.
The drill bit sets multiple spray orifices, and difference can jet, whitewashing and spray powder.
The inserted pin special when precast hollow component sinks in place, be sheared under the pulling force that extraordinary stake machine provides it is disconnected or
It is self-possessed by pile body and cuts, realizes vanes retract.
1) setting-out, extraordinary stake machine are in place；
2) large size prefabricated hollow unit is inserted in drilling rod by dismounting drilling rod, connection can undergauge bit, at this time can undergauge bit
Moving vane one, moving vane two, moving vane three are open configuration；
3) mechanical driver unit, lower turn of cutting, as needed can whitewash simultaneously liquid, air or dry powder are opened；
4) to after designed elevation, above mention can undergauge bit, hale shearing inserted pin special, moving vane one, moving vane two,
Moving vane three retracts, and is close to shaft；
5) propose drilling rod, reinstall can inserted pin special on undergauge bit, move back to next construction location and repeat front 1)
~5) step is constructed.
Compared with prior art, the present invention provide one kind can undergauge bit and its construction method, have the advantage that
1, using piling construction after the digging of drill bit elder generation, noiseless in work progress, without squeezing soil, effect on environment is small；
2, high-strength plate tooth, pick can be inlayed on drill bit moving vane, can carries out constructing into rock, holds prefabricated components
It carries power to be not fully exerted in firm hard formation, reduces construction cost；
3, drill bit is designed using more spray orifices, can be selected according to geological conditions spray slurries, dry powder or other reinforcement materials into
Bearing capacity of single pile is reinforced and improved to row；
4, can undergauge bit cutting construction, after pile sinking can undergauge extract, it is convenient to construct, and pile sinking is high-efficient.
