Specific embodiment
The technical solution of the patent is explained in further detail With reference to embodiment.
Fig. 1-6, a kind of slope reinforcement rod piece, including rod piece ontology, nut and backing plate are please referred to, during the rod piece ontology is
The empty body of rod and rod piece ontology is made of nut construction section, the front end body of rod and the rear end body of rod, nut and backing plate mating can be mounted on
On the body of rod of front end, it can be realized the perfusion of slurry by hollow lever, be provided with several connecting holes on the rear end body of rod, connecting
It is connected with the fiber hose of inner hollow at hole, seepage hole is provided on fiber hose, slurry enters it from the perfusion of rod piece body interior
Afterwards, fiber hose can be entered by connecting hole, impassioned fiber hose is propped up to extend to inside soil body, into inside fiber hose
A part of slurry can also be oozed out from seepage hole to be combined with soil body realization.
The end of the rear end body of rod is connected with several fiber hoses, and fiber hose energy after injecting slurries is arranged in end
So that the entire body of rod is further extend into inside soil body, increases the dynamics of anchoring.
Several slurry outlets that can go out slurries are offered on the front end body of rod, the setting of slurry outlet can be such that slurry enters
To the space of rod piece ontology and the opinion of pore-forming, guarantee the effect of entire rod piece ontology when in use.
The fiber hose is mounted on connecting hole by way of pasting.
The connecting hole is evenly arranged, and casing is connected on one end sealing other end of fiber hose, after casing is sheathed on
Side pole body is simultaneously fixed on the door through an adhesive method on the body of rod of rear end and guarantees that fiber hose is corresponding with connection hole site.
Described sleeve pipe can be connect with a plurality of fiber hose simultaneously.
A kind of application method of slope reinforcement rod piece, comprising the following steps:
It punches to form pore-forming step 1: carrying out side slope；It carries out mortar to mix and stir to form forming slurry, and guarantees gathering materials most in slurry
Big partial size is less than the 1/2 of connecting hole aperture；The selection of aggregate size will guarantee the energy after being injected into rod piece body interior that gathers materials
Enough smoothly enter in fiber hose；
Step 2: rod piece ontology is inserted into the pore-forming in the first step, and guarantee the rear end body of rod the Inner Front End body of rod outside, this
Fiber hose is attached to rod piece outer body under state；Before injecting slurry, fiber hose be it is softer, bar can be attached to
On part outer body side, it can guarantee that rod piece ontology early period is smoothly inserted into the inside of pore-forming in this way；
Step 3: successively installing backing plate and nut in nut construction section；
Step 4: from the forming slurry from the outside port of rod piece ontology into the internal high pressure of the rod piece ontology injection first step,
Stop slip casting when grouting amount and grouting pressure reach design requirement, when actual high-voltage injects slurry, to combine Different field
Design requirement carry out high-pressure slip-casting, the requirement of design can be reached in this way.
Tensioning fixation is also carried out after the completion of entire high-pressure slip-casting, reaches the 75% of predetermined strength in concretion body strength
And more than 15MPa after, carry out pre- tensioning, need to carry out pre- tensioning before formal tensioning, the tensioning of design requirement is reached after locking
Lock value, locking load should be higher than that tensioning lock definite value, according to the regulation to stress loss, the 1.1- of general desirable tensioning lock definite value
1.2 again.
Maximum particle diameter of gathering materials in the first step slurry is less than the 1/3 of connecting hole aperture.
The present invention connects the fiber hose for being provided with multiple seepage holes, shape between fiber hose and rod piece ontology on rod piece ontology
At the structure for being similar to tree root, as the root system stretched out from rod piece ontology peripheral wall, expands rod piece ontology and contact the effect of the soil body
Area is added significantly to anchor force；Stretch fiber hose using high pressure in slip casting, the rear slurry of fiber hose stretching, extension can
It is oozed out from seepage hole, the range for extending slurries in the soil body is bigger, and it increases anchor pole and contacts the active area of the soil body, enhancing
The mechanical strength and globality of the soil body, make rod piece ontology specifically better consolidation effect.
Rod piece ontology connects fiber hose, and fiber hose is made of soft high fiber strength strains, and tube wall is provided with tiny infiltration
Hole.
Rod piece ontology uses high-pressure slip-casting, and under high-pressure slurry effect, fiber hose such as tree root are protruded into the soil body, and pass through
Tube wall pore permeates slurries, solidifies tube wall surrounding soil.
The present invention ensure that the connection of fiber Grouting Pipe Yu rod piece ontology by the way that fiber hose to be connect with rod piece ontology
Power；By hollow rod piece ontology to fiber hose high-pressure slip-casting, fiber Grouting Pipe is protruded into the soil body, slurries are soft by fiber
The exudation of pipe pipe peripheral wall seepage hole, solidification is contacted with surrounding soil, is increased anchoring section and is contacted the active area of the soil body, is significantly increased
The anchor force of anchor pole.
The preferred embodiment of the patent is described in detail above, but this patent is not limited to above-mentioned embodiment party
Formula within the knowledge of one of ordinary skill in the art can also be under the premise of not departing from this patent objective
It makes a variety of changes.
