Description
Technical field
Present invention relates particularly to the construction methods of glass multiple anchor cable muscle, glass multiple anchor cable and anchor pole.
Background technique
Bolt support technology structure is simple, easy for construction, low in cost, stability is good, strong applicability, compared to traditional
Using the support system of concrete material, advantage of the mooring rod technique in terms of cost, duration, applicability is more apparent, especially faces
The supporting facility of when property, and with the propulsion of urbanization process, underground parking, underground tunnel, subterranean commercial area, underground
The engineerings such as railway, high-lager building basement are more and more, engineering specifications more sophisticated, and anchor pole process costs are low, short time limit, apply
Work noise is small, and than the high request that traditional support pattern more meets city ground anchorage, but disposable support anchor rod can be in the soil body
In leave the materials such as reinforcing bar, steel strand wires, steel wire, difficulty also is increased to later planning engineering construction while wasting material,
Virtually cause the one kind " pollution " in engineering construction place.People devise Recyclable anchor rope thus, and Recyclable anchor rope is current
Mainly have mechanical, rotary and three kinds of hot melten type.
Mechanical Recyclable anchor rope controls the physical aspect of supporting body in anchor rod anchored section mechanically to adjust
The connection type of anchor pole and anchoring body, in the anchor rod anchored stage, supporting body is closely coupled with anchoring body, passes through bottom bearing and friction
Power provides the anchor force of anchor pole, tears core recovery stage open in anchor pole, by artificial regulatory, reduces supporting body volume, keeps bottom bearing big
Width reduces, so that anchor rod body be extracted out.But usually using in situation, anchor pole tensioning fixation for a period of time after, be difficult to pass through people
Supporting body volume is reduced in work regulation, and the ratio that anchor pole tears core recycling open is lower.
Rotary Recyclable anchor rope refers to that the soap-free emulsion polymeization body of rod, in rotary type, passes through in anchoring body after anchor pole use
One end of the body of rod is turned round in tensioning, recycles anchor rod body, due to having larger bending in supporting body when the body of rod tears core recycling open, is recycled
The body of rod out basically can not be reused.
Hot melten type Recyclable anchor rope technology refers to that anchor rod body overall length or anchoring section are viscous by hot melt material and anchoring body
Knot together, after anchor pole use, by heating to anchor rod body or heating to the cooling fin being embedded in hot melt material, makes
Hot melt material is converted to semisolid even liquid by solid-state and recycles out anchor rod body to reduce anchor rod body friction,
But this method stability is poor, and when usual anchor pole pore-forming, aperture is little, the bond effect between hot melt material and the soil body
Difference causes anti-pulling of anchor bar less than normal, and anchor rod body is powered when heating, and the heat-conductive characteristic of the body of rod is unstable, general anchor pole bar
When body is shorter, the heat diffusivity of the body of rod is fine, and when anchor rod body is partially long, the fusing effect of hot melt material is not satisfactory.
Glass fibre reinforced composion (Glass Fiber Rein Forced Polymer, abbreviation GFRP) is a kind of
Glass fibre reinforced composion is convenient for cutting, by glass fibre and resin through heat fusion into using glass fibre composite wood
Expect stake, be used for cable bolting structure, can saving steel, protect environment, and can fundamentally solve the problems, such as corrosion of component, to rear
Phase engineering does not influence, and does not need to recycle.
