Screw piles gaw, kaja ai hte grup yin hpe n hkra ai npawt nhpang ladat langai hku nna, aten kadun nta ni, nhtoi htoi ai jak ni, matut mahkai nta ni hte kaga shara ni hta grai lang ma ai. Shanhte hpe gawgap na matu loi ai hte ngang kang ai hkam sharang lu ai atsam hpe jaw ya ai. Raitim, tatut jai lang ai shaloi, bungli masing a shimlum lam hte hkam kaja lam hpe hkam la lu na matu lawu na madung myit yu ra ai lam ni hpe atsawm sha hkan sa ra ai.
1. Ga hte seng nna htuk manu ai lam hpe jep joi ai lam
Screw piles ni a hkam sharang lu ai atsam gaw lamu ga masa hte grai matut mahkai nga ai. Ga garan ginhka ai lam, n-gun n-gun jat ai lam, ga npu na hka madang ni hpe sawk sagawn na matu, ga n-gun n-jaw shi yang, lamu ga masa hpe atsawm sha sawk sagawn ra ai. Soft soils ni hta grau galu ai pile (sh) grau kaba ai diameter ni ra ai, hard rock formation ni hta gaw screw galaw ai hpe karum na matu hte jak rung ni grai law hkra n-gun n rawng ai (sh) pile hkra machyi ai lam hpe koi lu na matu pre-drilling galaw ra na re.
2. Pile hpe hkrang shapraw nna lata la ai lam
Htap htuk ai pile arung arai (ga shadawn, n-gang, concrete-coated n-gang) hte thread pitch hpe n-gun ra ai lam ni hpe madung tawn nna lata la na. Pile diameter, galu kaba ai, thread amyu ni hpe jahpan hku nna dawdan ra ai, dai hku nna pullout hte compressive n-gun ni gaw design madang ni hte maren rai na matu re. Hka lim ai shara ni hta lang na matu, hka lim ai hpe ninghkap ai -coating (sh) galvanizing ra ai.
3. Gawgap ai lam hpe hkang ai
Gawgap ai shaloi, n-gun n-gun shayawm ai majaw, n-gun shayawm ai atsam yawm mat na hpe koi lu na matu, nlung n-gun (verticality) gaw 1% kaw na n-htum mat hkra sadi ra ai. Screwing speed gaw grai lawan ai majaw ga hpe n hkra hkra (sh) pile deformation n byin hkra maren sha rai ra ai. Hard interlayer (sh) n kaja ai ninghkap ai lam ni hkrum katut yang, operation ni hpe jahkring kau nhtawm, hpa majaw byin ai hpe sawk sagawn ra ai. Atik anang screw galaw ai majaw, pile hpe daw mat chye ai.
4. Quality hpe jep joi nna hkap la ai lam .
Gawgap ngut ai hpang bearing capacity hpe chyam yu ra ai. Masha law malawng lang ai ladat ni hta static load chyam dinglik ai (sh) dynamic shang wa ai ladat ni lawm ai. Pile shang wa ai sung ai shara gaw hkrang shapraw ra ai lam ni hte maren rai kun ngu ai hpe jep yu nna, grup yin ga hta grai ahkyak ai shingbyi shara (sh) n-gun n rawng ai shara ni nga ai kun ngu ai hpe yu yu ra ai.
5. grup yin hte shimlam masat masa ni
Gawgap ai shara hta ahkang n lu ai ni n shang wa hkra sadi jaw ai kumla ni hpe mara da ra ai. Hpaji masa hku nna hkala nba n byin hkra, jak rung ni hpe jai lang ai shaloi, kungkyang ai masha ni galaw ra ai. Katsi katsang rai mat ai nlung npan baw ni (sh) htu shaw la ai ga ni hpe atsawm sha kabai kau nna grup yin hpe hkra machyi ai lam n law hkra galaw ra ai.
Tsun ga nga yang, screw pile gawgap ai shaloi, sut masa hte kam hpa mai ai akyu ni hpe hkum tsup hkra hkam la lu na matu, lamu ga masa, hkrang shapraw ai lam, hte masat da ai lam ni hpe myit yu ra ai, dai hte rau, grai sawng ai ladat hpe hkang zing nna hkap la ra ai.
