Description
Technical field
The present invention relates to geotechnical engineering, especially a kind of prestress anchorage cable can mend tensioning anchor seal structure.
Background technique
It is highly developed that prestress anchorage cable technology is applied to geotechnical engineering reinforcing, but for a long time, prestressing force is damaged
Mistake problem is not solved very well, and the accident of reinforcing engineering failure is caused to happen occasionally after loss of prestress, individual provinces and regions
Therefore application of the prestress anchorage cable in the permanent works such as side slope, foundation pit is also limited.Prestressed anchor cable anchorage all used in the past
Concrete sealing off and covering anchorage needs to cut steel strand wires extra outside anchor head, in this way, for loss of prestress for end socket beauty before sealing off and covering anchorage
Need to mend the anchor cable of tensioning since anchor cable remaining outside anchor head is shorter, tensioning machine clamp can not clamp, and cannot achieve benefit tensioning, together
When, concrete sealing off and covering anchorage is removed very difficult.Loss of prestress cannot mend tensioning, will jeopardize engineering safety.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of prestress anchorage cables can mend tensioning anchor seal structure, in anchor cable
Occur quickly carrying out benefit tensioning when loss of prestress, it is ensured that rock-reinforcing engineering safety, and realize that geotechnical engineering is reinforced dynamic
State design and Dynamic Construction.
The technical solution adopted by the present invention to solve the technical problems is as follows:
A kind of prestress anchorage cable of the invention can mend tensioning anchor seal structure, including billet, anchorage and anchor cable, anchorage have
The anchor cable hole of circumferentially spaced-apart setting, it is characterized in that: the anchor cable rear portion passes through anchor cable hole and exposure anchorage end face certain length, with
Anchorage forms the casing being detachably connected and closes anchor cable exposure section in the inner, casing back-end closure, and anti-corrosion is perfused in inner cavity
Grease;It is detachably connected shield on the billet, which surrounds anchorage, casing in the inner.
Ring groove with anchor cable hole coaxial line is set on the anchorage end face, and ring groove is inserted into casing front end, and logical
Connected structure is crossed to be detachably connected with anchorage formation.
The invention has the advantages that the closing safeguard structure of anchor cable can be dismantled, and anchor cable rear portion exposure anchorage end face
Certain length can quickly carry out benefit tensioning when loss of prestress occurs in anchor cable, it is ensured that rock-reinforcing engineering safety, and realize rock
The dynamic design and Dynamic Construction of native engineering reinforcement;Have the characteristics that it is firm it is practical, economical, construction it is quick and convenient, have and preferably push away
Wide application prospect, and meet the requirement of environmental protection.

Specific embodiment
Present invention will be further explained below with reference to the attached drawings and examples.
Referring to Figures 1 and 2, it includes billet 10, anchorage 11 that a kind of prestress anchorage cable of the present invention, which can mend tensioning anchor seal structure,
With anchor cable 20, anchorage 11 has the anchor cable hole 12 of circumferentially spaced-apart setting, and 20 rear portion of anchor cable passes through anchor cable hole 12 and exposure anchor
Have 11 end face certain lengths.It forms the casing 30 being detachably connected with anchorage 11 to close 20 exposure section of anchor cable in the inner, casing
Anti-corrosion grease 31 is perfused in inner cavity, prevents the steel strand wires of anchor cable 20 from corroding for 30 back-end closures.It is detachable on the billet 10
Shield 50 is connected, which surrounds anchorage 11, casing 30 in the inner, plays protective action.Closing outside anchor cable 20
Safeguard structure can be dismantled, and 20 rear portion exposure anchorage end face certain length of anchor cable, can be fast when loss of prestress occurs in anchor cable
Speed carries out benefit tensioning, it is ensured that rock-reinforcing engineering safety, and realize dynamic design and Dynamic Construction that geotechnical engineering is reinforced.
Referring to Figure 1 and Figure 3, the ring groove 13 with 12 coaxial line of anchor cable hole, casing 30 are set on 11 end face of anchorage
Ring groove 13 is inserted into front end, and is detachably connected by connected structure and the formation of anchorage 11, to facilitate construction.Connected structure can
It is a kind of structure connected structure the simplest, i.e., the described grafting knot shown in Fig. 4 to use the diversified forms such as spring arch clasp
Structure includes the card slot being set on 13 side wall of ring groove, and the ring-like boss in setting 30 front end side wall of casing, card slot, ring
Type boss is corresponding and is adapted.Casing 30 is made of plastic material, has certain flexibility.
Referring to Figures 1 and 2, ventilation hole 52 is arranged in the both lateral sides of the shield 50, and drain hole is arranged in bottom bottom position
53.The main function of ventilation hole 52 is to prevent temperature in sealing off and covering anchorage too high, plays cooling effect.Similar blinds in 52 structure of ventilation hole
Well format, upside imperforation, lower opening avoid rainwater from entering in shield 50.The effect of drain hole 53 is to exclude extreme item
Enter the ponding in shield 50 under part.The shield 50 is made of stainless steel, aluminium alloy or engineering plastics.
Referring to Figures 1 and 2, also settable coaxial dynamometer 40, coaxial dynamometer 40 between the billet 10, anchorage 11
