Abstract
The invention discloses an anti-corrosion prefabricated grouting anchor rod for a highly corrosive environment. The anti-corrosion prefabricated grouting anchor rod comprises a reinforcing steel bar. The reinforcing steel bar is sleeved with a protective casing. A clearance is reserved between the protective casing and the reinforcing steel bar. The clearance is filled with an anti-corrosion binding material to form a solid cylindrical object, then the cylindrical object stretches into an anchor rod drilling hole, and cement paste is poured in to form the anchor rod. According to the anti-corrosion prefabricated grouting anchor rod, the reinforcing steel bar is sleeved with the protective casing, and the clearance between the protective casing and the reinforcing steel bar is filled with the anti-corrosion binding material to be connected into a solid whole; due to arrangement of two anti-corrosion layers, corrosion resistance of the reinforcing steel bar is greatly improved, the reinforcing steel bar can be effectively prevented from being corroded under a severe environment condition, and therefore the service life is prolonged, and durability of the engineering structure is greatly improved; moreover, for the reason that anti-corrosion binding paste is used for binding the reinforcing steel bar and the protective casing, enough high binding force is guaranteed between the protective casing and the reinforcing steel bar, the requirements for anchor rod reinforcing steel bar corrosion resistance and pulling resistance in relevant industry standards can be met, and huge economic benefits and social benefits are achieved.
Description
Technical field
The present invention relates to a kind of anchor pole, particularly to a kind of corrosion-resistant prefabricated grouted rock bolt for strong corrosive environment.
Background technology
Urban development speed is increasingly faster now, and high-rise and building gets more and more, and basement increases the most therewith.?
Under water buoyancy, the independent basement of high-rise periphery or band low layer annex basement usually need to utilize anchor pole anti-floating.
Anchor pole is the anchoring system that pulling force is delivered to stable rock stratum or the soil body, and its one end is connected with engineering works,
The other end gos deep in stable rock stratum or the soil body.Some anchor pole is divided into free segment and anchoring section, there is also only anchoring section
Situation, free segment is the shank portion utilizing elastic elongation that pulling force passes to anchoring body；Anchoring section refer to by injecting cement paste or
Pulling force is delivered to around rock stratum or the shank portion of the soil body by machinery.Composition anchor pole must possess three below factor: 1.
One tensile strength is higher than the body of rod of Rock And Soil；2. body of rod one end can be in close contact with Rock And Soil and form friction (or bonding) resistance
Power；3. the body of rod is positioned at the other end outside Rock And Soil and can form the Radial resistant force to Rock And Soil.
Anchor pole reinforcing bar is frequently utilized in anchor pole as a kind of above-mentioned body of rod.Hole in rock stratum with the soil body, anchor pole reinforcing bar
It is placed in armature boring, then constitutes anchor pole by grouting cement mortar.Anchor pole reinforcing bar is embedded in rock stratum and the soil body, making of it
The durability of self is depended on the life-span.Affect anchor pole reinforcing bar durability because have, prestressing force tonnage is excessive, material, construction work
Skill is improper and environmental corrosion etc., and wherein, the maximum factor of impact is corrosion, the corrosion of the durability of anchor pole reinforcing bar and anchor pole reinforcing bar
Destructiveness has direct relation.
The measure of existing raising anchor pole reinforcing bar corrosion resistance has: be (1) coated with (resin) plating (zinc) anticorrosion at anchor pole rebar surface
Layer, but coating operation can only be carried out in professional factory, and anchor pole reinforcing bar is in transport and work progress, and anticorrosive coat is easily rubbed
Scratch destruction, thus it cannot be guaranteed that Corrosion Protection；The most also have and use the plastic material of highly corrosion resistant and corrosion-resistant steel bar (stainless
Steel reinforcing bar, rare earth reinforcing bar etc.) substitute anchor pole reinforcing bar, but, both materials costly, cause construction cost higher, it is impossible to
It is widely popularized applicable.
