Description
Technical field
The present invention proposes a kind of inflation soil compaction anchor pole, soil property or protection, reinforcing and the rescue of soft soil-slope available for building foundation pit supporting engineering.Common grouted anchor bar can be replaced, engineering application value is high.
Background technology
Existing anchor pole is mainly preexisting hole grouted anchor bar, relies on the rubbing action between the slip casting Seed harvest and Rock And Soil of anchoring section and produces anchor force.General preexisting hole grouted anchor bar has following three shortcomings：One is that under given geological conditions, the increase of anchor force can only be by increasing the parameters such as bolt diameter, length, and the tune increasing of these parameters result in huge economic waste, increases rock-bolt length sometimes and is also limited by peripheral space；Two be that the lacing wire of anchor pole and slip casting Seed harvest are all deposited in the soil body of underground after anchoring task is completed, and the later development to the periphery underground space, which is utilized, causes obstacle.Three be that bolt grouting construction is completed and slip casting Seed harvest is reached after some strength, could form anchor force, cause construction speed slow；The completion moreover, anchor pole is once constructed, anchor force can not then increase, and when the dangerous situations such as sliding trend occurs in side slope, it is entirely possible to avoid the further unstability of side slope if can take measures to adjust the anchor force for increasing anchor pole.
Inflation anchor bar can effectively solve the above mentioned problem of grouted anchor bar.But existing inflation anchor bar is all much that rubber fixation colligation is formed into anchoring section in hollow pull rod, the problem of being primarily present two aspects：One is the failure to limitation rubber pneumatic bag expands to two ends, and air bag diameter increases during air pressure increase, and termination position is to aperture bottom hole dilatancy, the easy Explosive Failure of air bag, therefore air bag internal pressure very little, and anchor force is low；Two be that the side rubber of air bag is directly contacted with anchor hole Tu Bi, and anchor force needs all to be delivered on rubber so that deformation of the air bag along pull bar direction is very big, and to a certain extent, the wall thickness for also resulting in air bag rubber is thinning for pulling force increase, so as to occur Explosive Failure.Therefore, conception at present only with respect to inflation anchor bar and test report, the rarely seen engineer applied on inflation anchor bar.
A kind of inflation soil compaction anchor pole proposed by the present invention has following features：One is to be provided with front and rear end-stopping plate, side guard plate and rubber sheath for air bag, it can adapt to large range of be radially expanded deformation (air bag expansion generally reaches more than 2 times of diameters), and the termination extrusion linear deformation after air bag expansion is effectively limit, therefore can be with the blowing pressure of augmented airbag；Two be to set side soil compaction steel disc for air bag, and soil compaction steel disc is compressed anchor hole Tu Bi and produces frictional force by air bag, and frictional force is passed to pull bar (or lacing wire) by soil compaction steel disc again, and air bag rubber no longer tension is also just difficult thinning failure；Three be lose heart after inflation soil compaction anchor pole can realize complete recovery.Therefore inflation soil compaction anchor pole can avoid the defect of preexisting hole grouted anchor bar and existing inflation anchor bar completely.
