Description
Technical field
It is specifically a kind of recyclable swollen the utility model is related to a kind of anchor pole reinforced for geotechnical engineering or mine
Pipe anchor pole.
Background technology
Anchor pole is common tool during geotechnical engineering is reinforced.Suspension roof support is in constructing tunnel, foundation pit construction and stability of slope
Property reinforce in using more.Existing anchor pole type is more, widely applied in construction mainly to have tube-expanding type, swollen shell-type to stick
Eliminant, reverse wedge formula etc..There are following three big disadvantages for these support anchor rods, first, anchor force is relatively low, second is that not recyclable or return
It is big to receive difficulty, third, complicated construction technique.Apply at present it is more be swollen shell-type and adhesive type anchor pole, swollen shell anchor pole is by one
Determining means makes to open into the swollen shell in the anchor pole tail portion of drilling.This expansion sleeve bolt advantage is simple for process, is easy to construct, and at
This is low, the disadvantage is that anchor force is smaller, effect is poor.Adhesive type anchor pole is anchored by bottom powder stick, and advantage is that anchor force is larger,
The disadvantage is that cost is higher and not recyclable.
Many engineerings are to use anchor pole temporary supporting, are also disappeared since engineering construction terminates its effect, largely not recyclable
Anchor pole is stored in underground, not only influences ambient enviroment, occupies big quantity space, while can also influence similar engineer operation.It considers
Economy and recyclability are developed, are an inexorable trends using recoverable anchor rod.
Invention content
The purpose of this utility model is to provide a kind of recoverable tube expansion anchor poles, its anchor force is big, and constructing operation is simple,
Critical piece is recyclable, reduces construction cost.
The technical solution of the utility model is as follows：
A kind of recoverable tube expansion anchor pole, it is made of pull rod, hollow ram, tube expansion and expansion cone；Above-mentioned pull rod is
With the externally threaded body of rod, upper end is four prisms cylinder, and lower end connects pull rod and expands cone；Hollow ram be with female pipe,
The lower end of hollow ram connects push rod and expands cone；The lower part pull rod that above-mentioned tube expansion is sleeved on pull rod expands on cone, above-mentioned hollow
Pushing rod sleeve is on pull rod, and the push rod of hollow ram lower end expands cone and is against tube expansion upper end, and hollow ram upper end is collet, is being drawn
Bar top sets pallet and nut.
Above-mentioned tube expansion is highstrenghtpiston, and tube expansion is internally provided with expander, and expander is equipped with expansion joint (E.J.).
The utility model has the advantage of：1, this anchor-holding force of anchor bolt is big, and rotating rod can be such that the push rod at tube expansion both ends expands
Big cone and pull rod expand cone and enter tube expansion, and then tube expansion is made fully to expand.Tube expansion squeezes to form friction anchoring power with country rock.
2, easy to operate with this anchor pole, as long as hollow ram is fixed, rotating rod can, facilitate construction.3, critical piece pull rod, in
Empty push rod can recycle completely, at low cost.
Description of the drawings
Fig. 1 is the utility model embodiment overall structure diagram；
Fig. 2 is the drawbar structure diagram of the utility model embodiment；
Fig. 3 is the utility model embodiment hollow ram structural schematic diagram；
Fig. 4 is the utility model embodiment tube expansion cross-sectional view；
The dilating principle figure of Fig. 5 the utility model embodiments tube expansion in the case where expanding cone effect.
Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings.
By Fig. 1~5 it can be seen that this recoverable tube expansion anchor pole, it is by pull rod 1, hollow ram 4, tube expansion 6 and expands cone
Body is constituted；Above-mentioned pull rod 1 is with the externally threaded high intensity body of rod, and upper end is four prisms cylinder, is facilitated using mechanical rotation, lower end
Even pull rod expands cone 7；Hollow ram 4 is with female double-strength pipe, and the lower end of hollow ram connects push rod and expands cone
5；The lower part pull rod that above-mentioned tube expansion 6 is sleeved on pull rod expands on cone 7, and above-mentioned hollow ram 4 is sleeved on pull rod 1, hollow ram
The push rod of lower end expands cone 5 and is against 6 upper end of tube expansion, and hollow ram upper end is collet 10, and pallet 3 and nut are set on pull rod top
2。
It can see by Fig. 1, Fig. 4, Fig. 5, above-mentioned tube expansion is plastics, and tube expansion is internally provided with expander 8, and expander sets 1
Expansion joint (E.J.) 9, two expansion body spaces 11.Expander both ends are grading structure.
Pull rod expand cone 5 and push rod expand cone 7 can under pull rod and push rod turning effort jacking tube expansion 6, by with
The extruding of expander 8 causes expansion joint (E.J.) 9 to become larger and then tube expansion is made to expand, and the tube expansion after expansion forms frictional force anchoring with shoulder bed effects.
Reversely back-outing hollow ram 4 can make pull rod expand cone 5 and push rod expansion cone 7 and expand the extruding disappearance of body 8, and tube expansion 6 is extensive
Home shape disappears with country rock frictional force, that is, realizes recycling.
Pull rod 1, hollow ram 4 and tube expansion 6 are assembled and are inserted into drilling, is then rotated by drill hole of drilling machine first when construction
Vising the collet 10 of hollow ram 4 while pull rod 1 with spanner prevents from rotating, until pull rod cannot rotate.Again by pallet 3
It is fastened with bolt 2.Reversely rotate the recycling that anchor pole can be realized in pull rod 1.
