Helical Pile los yog av Ntsia Hlau

Helical Pile los yog av Ntsia Hlau:

Helical pawg yog ib daim ntawv ntawm prefabricated sib sib zog nqus foundation. Raws li hinted nyob rau hauv nws lub npe, helical pawg txawv los ntawm lwm lub hauv paus sib sib zog nqus thiab yog qhov tseem ceeb tshaj plaws rau muaj spiraling hniav raws lawv shafts, as opposed to muaj ib tug kuj zoo li zoo li cov pawg tsav thiab micropiles.

Qee lwm lub npe rau helical pawg muaj xws li helical piers, helical anchors, ntsia hlau pawg, thiab ntsia hlau hauv paus. Txawm hais tias tej zaum yuav muaj qee qhov sib txawv me me hauv kev sib tw npe, cov npe no feem ntau siv sib hloov. Yam tsawg kawg nkaus, lub hauv paus ntsiab lus ntawm tag nrho cov no tseem zoo ib yam.

Drilled Cast-in-Place Concrete Piers:

• 12" diam piers
• 6'-0" sib sib zog nqus piers rau (2) Rov qab ceg; 5'-0" sib sib zog nqus piers rau (2) Pem hauv ntej ceg
• Rebar tawb yuav tsum tau (ntau npaum li cas nyob ntawm seismic tsim qeb ntawm qhov chaw)

Tsav Steel Piles:

• W6x7 pawg assumed (4 "dav los ntawm 6" sib sib zog nqus nrog ib tug steel luj ntawm 7 lbs. ib ko taw)
• 7'-3" sib sib zog nqus pawg rau (2) Rov Qab Ob txhais ceg; 6'-0" sib sib zog nqus pawg rau (2) Pem hauv ntej ceg

• Txhua pawg helical los yog av ntsia hlau yog nruab rau hauv thaj tsam ntawm 5 mus rau 6 ft. (ib txwm).
• Load xeem yuav tsum tau siv qhov tsawg kawg nkaus ntawm kev nyab xeeb ntawm 1.5 thiab feem ntau siab dua thaum tsuas yog xaiv tus naj npawb ntawm cov thauj tog rau nkoj (ib lub chaw tsim khoom thauj tog rau nkoj).
• Muab cov ntsiab lus ntawm cov khoom kuaj sim mus rau Tus Kws Lij Choj Cov Ntaub Ntawv rau kev tshuaj xyuas, kev pom zoo, thiab xa mus rau qhov kev txiav txim plaub ntug.

Earth Anchor:

• Txhua lub thauj tog rau nkojtsavmus txog 2 ft. tob (nruab nrab rau feem ntau Osprey installations)
• Load test Back Leg anchors rau 1400 lbs. thiab pem hauv ntej ceg anchors rau 500 lbs. (Qhov tseem ceeb ntawm kev nyab xeeb ntawm 1.5).
• Muab cov ntsiab lus ntawm cov khoom kuaj sim mus rau Tus Kws Lij Choj Cov Ntaub Ntawv rau kev tshuaj xyuas, kev pom zoo, thiab xa mus rau qhov kev txiav txim plaub ntug.
