Description
Technical field
The present invention relates to rig field, be specifically related to a kind of multi-functional reamer.
Background technology
Underground hole expansion work mainly uses at trenchless engineering.Trenchless technology, external title TT technology, i.e. TrenchlessTechnology, also known as horizontal directional drilling technology, refers to a kind of techniques and methods detecting, check, repair, change and lay various subsurface utility (pipeline and cable) when not excavating earth surface.Start from the horizontal directional drilling pipelaying techniques (also known as no-dig technique pipelaying techniques) of nineteen seventies, be commonly used to river crossing, water channel, street, speedway, railway, airport, runway, river shoal, island, architectural complex, the conduit carrying out the laying of oil, natural gas, Natural Water, sewage and other fluids and electric power and telecommunication cable is laid.No-dig technique guide digging pipeline installation is at traditional pipe jacking method and the pipe-laying technique that directed horizontal drilling laying-out tube process basis can not be introduced modern guiding technique and grow up.Its sequence of construction is roughly: utilize the pipelayer rig being placed in ground, along waiting that the planned course spreading line is first drilled to a pilot hole (pilot hole), then use the drilling rod passed through, at unearthed end, reamer is installed and return expansion, be extended to the diameter of applicable production pipe laying, then pipeline to be laid is drawn in hole, under the prerequisite not destroying landforms, realize pipeline construction.
When there is lock of tool drilling in tradition reamer, because reamer is oppositely without cutting power, now oppositely can draw reamer become reaming construct in a difficult problem, the construction risk that simultaneous is larger, has therefore had influence on efficiency of construction.
Board-like reamer is mainly used in the reaming construction on the stratum such as argillic horizon, sandy soils, pebble layer, backfill, slag stone.Because reamer wearing and tearing often need to change reamer in no-dig technique reaming drilling construction, and the just part wears that the reamer changed has, not structural damage.
Suitable centralizer or central positioner all should being installed additional before reamer when no-dig technique reaming is crept into, to reduce the unstability in drilling process, reducing the stressed drilling rod in front because swinging the lateral stress caused.Centralizer generally has several forms such as pipeloop formula centralizer, tub centralizer, straightedge centralizer and roller centralizer.Wherein pipeloop formula central positioner is applicable to various stratum, is a kind of wide spectrum locator.Wherein have a kind of pipeloop formula central positioner adopting the correcting of two-stage guard ring, its retainer surfaces is welded with tungsten carbide solder flux or local seting welding carbide carries out surface peening, and the structure of this pipeloop formula central positioner is very similar to the structure of board-like reamer.
Summary of the invention
For the defect existed in prior art, the object of the present invention is to provide a kind of multi-functional reamer, namely described multi-functional reamer can use as board-like reamer, can use again as pipeloop formula centralizer.
For reaching above object, the technical scheme that the present invention takes is: a kind of multi-functional reamer, comprise mandrel, described mandrel is quill shaft, and described mandrel one end is male connection, and the other end is female adapter, described mandrel is arranging a rubber ring near described male connection place, described mandrel two ends are all provided with dividing plate, are provided with water cavity pipe between described dividing plate, and described mandrel two ends external surface is respectively provided with six sprinkling seats; Floor, evenly distributed six pieces of described floors around described mandrel, described floor is trapezoidal plate, and described floor is provided with two trapezoidal holes, and described trapezoidal hole is arranged along floor axial symmetry; Pipeloop, described pipeloop is set on described floor; Pick, described pick is detachable to be arranged on the inclined-plane, both sides of described floor.
On the basis of technique scheme, described female adapter and described male connection match.
On the basis of technique scheme, described dividing plate is provided with some partition board holes.
On the basis of technique scheme, described collar surfaces is welded with tungsten carbide solder flux.
On the basis of technique scheme, described sprinkling seat is evenly distributed around described mandrel, is provided with hole for water spraying in described sprinkling seat.
Compared with prior art, the invention has the advantages that:
(1) the multi-functional reamer in the present invention, namely can use as board-like reamer, can be used as again pipeloop formula centralizer and uses.
(2) there is pick in positive and negative two faces vertically with the multi-functional reamer in the present invention, realize the reaming work of two different directions, therefore effectively can solve reamer jammed problem in the process of pulling back.
