Abstract
The invention relates to a method for constructing the sand pulp one-tie expanding anchor rod, and a relative device, wherein in traditional method, since the sand mud has lubricant function on the hole to reduce the friction, the main strength of anchor rod is low, and the cement pulp has high cost; in said invention, the anchor rod driller drills to the design depth, then drawing out the driller and pouring sand pulp or fine concrete, to form hole, and mounting anchor rod main bar, drawing back to complete the expanding head for three times, while the pouring pressure is between 0.5-9Mpa.
Description
Technical field:
The present invention relates to a kind of sand-filling one-step-forming enlarged anchor pile construction method and device thereof.
Background technology:
Behind the anchor pole traditional method elder generation preexisting hole that uses in the building foundation pit supporting at present, the skyhook reinforcing bar, cement injection becomes anchor pole again, this job practices operation is many, quality be difficult for to guarantee, moisture anchor pole in the soil layer particularly is earlier with behind the mud off, the skyhook reinforcing bar, cement injection clear hole displacement again, because mud has the frictional force of lubrication anchor pole to reduce to the hole, anchor pole main body intensity is low, cement paste cost height, shortcomings such as construction period length.
Summary of the invention:
The purpose of this invention is to provide and a kind ofly finish from creeping into to pour into once, technology is new, and quality is good, sand-filling one-step-forming enlarged anchor pile construction method that efficient is high and device thereof.
Above-mentioned purpose realizes by following technical scheme:
Annotate sand and once expand an anchor rod construction method, it is characterized in that: carry brill behind the jumbolter drilling to completion, annotate mortar or fine-stone concrete when carrying brill, the limit is carried and is bored marginal not mortar or fine-stone concrete pore-forming, lay anchor pole master muscle again, pull back then and finish enlarged footing, retract to send to and come and go more than three times, form complete mortar enlarged footing, grouting pressure is between 0.5～9Mpa.
Once expand an anchor pole device, its composition comprises: anchor pole master muscle, one group of bracing frame, on the described anchor pole master muscle hinge point is installed, describedly be fixed with one group of bracing frame that enlarges the ironwork leaf and be installed on the described hinge point, the termination of described bracing frame lower end is expanded with return and is stretched the spring tension, angle≤60 of bracing frame upper end and the formation of anchor pole master muscle °, lower end and anchor pole master muscle form≤30 °, upper end+lower end≤90 °.
This technical scheme has following beneficial effect:
1. sand-filling one-step-forming enlarged anchor pile construction method of the present invention and device thereof directly inject mortar without mud when becoming bolthole in water layer is arranged, and have guaranteed hole quality, and undergauge does not avoid mud off to reduce the phenomenon of frictional force.
2. sand-filling one-step-forming enlarged anchor pile construction method of the present invention and device thereof are finished from creeping into to pour into once, and the construction link program is few, and speed of application is fast,, technology is new, and quality is good, the efficient height.
3. sand-filling one-step-forming enlarged anchor pile construction method of the present invention and device thereof, resistance to plucking frictional force height, noise is little, below 30 decibels.
4. sand-filling one-step-forming enlarged anchor pile construction method of the present invention and device thereof, construction costs is low, saves cost.

The specific embodiment of the present invention:
Embodiment 1:
Annotate sand and once expand an anchor rod construction method, carry brill behind the jumbolter drilling to completion, annotate mortar or fine-stone concrete when carrying brill, the limit is carried and is bored marginal not mortar or fine-stone concrete pore-forming, lay anchor pole master muscle again, pull back then and finish enlarged footing, retract to send to and come and go more than three times, form complete mortar enlarged footing, grouting pressure is between 0.5～9Mpa, when retracting anchor pole and become major part to have any problem, can adopt vibrating hammer and hydraulic tongs to send into and retract at skyhook, more can guarantee the formation quality of major part.Should work continuously at infusion mortar (fine-stone concrete or cement paste), should again creep into 500mm more than when resting midway and overlap.
Embodiment 2:
Embodiment 1 a described anchor pole device that once expands, its composition comprises: anchor pole master muscle 1, one group of bracing frame 5, on the described anchor pole master muscle 1 hinge point 3 is installed, the described bracing frame 5 that is fixed with one group of expansion ironwork leaf 2 is installed on the described hinge point 3, and spring 4 tensions are stretched with the return expansion in the termination of described bracing frame 5 lower ends, and enlarging ironwork leaf 2 can freely swing, be installed in the mortar body that pore-forming has poured into once expanding an anchor pole device, reintroduce 500mm after hanging down to the hole and form enlarged footing.
Embodiment 3:
The described anchor pole device that once expand of embodiment 2, angle≤60 that bracing frame 5 upper ends and anchor pole master muscle 1 form °, lower end and anchor pole master muscle 1 form≤30 °, upper end+lower end≤90 °.Bracing frame 5 lower ends put the return expansion and stretch spring 4, utilizing the return expansion to stretch spring 4 strains, by hinge point 3 expansion ironwork leaf 2 is outwards upheld, spring tension is 0.5～2Kg, when anchor pole master muscle 1 is installed in the hole, enlarge ironwork leaf 2 and play the leading truck effect at the bottom of the hole, expansion ironwork leaf still is not less than 1/3 part and is embedded in the anchor pole main body.
Claims (2)
1. a notes sand once expands an anchor rod construction method, it is characterized in that: carry brill behind the jumbolter drilling to completion, annotate mortar or fine-stone concrete when carrying brill, the limit is carried and is bored marginal not mortar or fine-stone concrete pore-forming, lay anchor pole master muscle again, pull back then and finish enlarged footing, retract to send to and come and go more than three times, form complete mortar enlarged footing, grouting pressure is between 0.5～9Mpa.
