Specific implementation mode
Here meaning existing for the bending slot further illustrated the present invention first, referring to attached drawing, heavy wall of the invention expansion
The wall thickness of pipe 5 is shown in that Fig. 5 is N times that the wall thickness of traditional thin-walled expansion tube 2 is shown in Fig. 2, with the increase of expansion thickness of pipe wall, is pulled out with moving back
The screw rod 1 of gradient voussoir is difficult to allow to the tube wall distending that its pico- distending to be inherently lost to too many nut tightening
Energy, that is, tighten nut this moment not instead of in the useful work for doing enhancing anchoring ability, doing confrontation or perhaps doing
Overcome the energy of intensity, rigidity of heavy wall expansion tube itself etc., however the tightening ability of nut 3 be it is limited, more what
Condition when the wall thickness increase of expansion tube to a certain extent when, it is its pico- distending is nearly all very difficult, needless to say look to it
Significantly distending realizes firm anchoring, thus, be exactly development and application that it hinders the prior art, therefore,
In order to solve this problem, the present invention is provided with bending slot 4, so, bending slot in the outer surface of upper of heavy wall expansion tube

The intensity, rigidity and toughness for opening part, on the other hand realize saving material, and the apparent size of the present invention is allowed to become smaller；Certainly, will
The end and outer surface of distending part are designed to edge of a knife shape, while being heat-treated to it, and then meet to anchoring hole
The cutting requirement from base expanding and base expanding from drilling or to anchoring hole bottom；By being heat-treated to distending part, can also realize
The purpose of flexible anchoring, flexible anchoring here is significantly thing, including further passes through sensor and read anchoring
Mechanical Data etc. does not just discuss here as space is limited.
In order to save material, the thick upper for the material saved being used in other words increase distending part is gone, this hair
The bright cross-sectional shape for further providing heavy wall expansion tube is that petal type shape is shown in Fig. 8, which is to pass through distending part
Open slot 11 is classified as the quartering, in practical applications, should be determined according to the size of the cross section of heavy wall expansion tube, transversal
Face is bigger, and tube wall is thicker, and petal is more, and the number of open slot is more, is easy bending in this way；It certainly, will be under open slot
End, which is done, expands circular hole processing, and so, then the stress concentration that can be further reduced at bending slot is not easy to be torn at bending slot
It splits.
In order to further reduce the cost, by the present invention heavy wall expansion tube be divided into up and down two parts, top be metal or
Anchor head made of Materials with High Strength, anchor head are located in location nut 10, and lower part is that pipe 12 is padded made of plastics or economic materials, should
Pad pipe ensure that screw rod is placed in the middle in anchoring hole, thus meet the application requirement of grouting and reasonable mechanical etc.,
See Figure 10.
In order to enhance anchoring effect, anti-skidding coarse or quil ratchet is made into the outer surface of the distending part of heavy wall expansion tube
Processing.
In order to further enhance anchoring effect, the anchor head is made into up and down the Double-anchor-head shape of distending simultaneously, sees Figure 13
And Figure 14.
In order to meet extensive use, it will move back and pull out gradient voussoir 6 and make with female independent shapes, it can be on screw rod 8
It is mobile, while raised anti-skidding muscle 9 is set on the side surface that gradient voussoir is pulled out in described moving back, see Fig. 7 and Figure 10, the protrusion
Anti-skidding muscle is in the open slot 11 above heavy wall expansion tube；Sub warhead is made it is, of course, also possible to will move back and pull out gradient voussoir
Shape is shown in Figure 12, pushes moving back for bullet shape to pull out gradient voussoir 16 so that heavy wall expansion tube distending by screw rod；Further become
It changes, also screw rod top can directly be made to not threaded bar, the end of bar is bullet shape, bar and heavy wall expansion tube
Lower part not threaded hole be fitted close, so directly percussion screw rod lower end so that heavy wall expansion tube distending.
According to different requirement or purpose is used, sets screw rod bottom end to tack, square toes, hexagon socket head or interior
Hexagonal flange, outer-hexagonal or outer-hexagonal flange face, internal-external hexagon or internal-external hexagon flange face, a word or cross recess are additional
