Mhedziso yeAnchor Hollow Steel Bars
Anchor hollow simbi mabara anogadzirwa muzvikamu zvine hurefu hwakareba hwe2.0, 3.0 kana 4.0 m. Iyo yakajairwa yekunze dhayamita yesimbi isina masimbi inotangira kubva pa30.0 mm kusvika 127.0 mm. Kana zvichidikanwa, masimbi asina maburi anoenderera mberi nekubatanidza nzungu. Mhando dzakasiyana dzezvibooreso zvezvibayiro zvinoshandiswa zvichienderana nerudzi rwevhu kana dombo. Imba yesimbi isina mhango iri nani pane bhaa yakasimba ine yakafanana-chikamu-chikamu nzvimbo nekuda kwemaitiro ayo ari nani ekuumbwa maererano nebuckling, denderedzwa uye kukotama kuoma. Mhedzisiro ndeyepamusoro buckling uye flexural kugadzikana kwehuwandu hwakafanana hwesimbi.

Zvishandiso zveSelf Drilling Anchor Rods
Mumakore achangopfuura, nekuwedzera kuri kuda kwerutsigiro rwe geotechnical, michina yekuchera yagara ichigadziridzwa uye kugadzirwa. Panguva imwe cheteyo, mari yebasa nerendi yakawedzera, uye zvinodikanwa zvenguva yokuvaka zvave zvichikwira zvikuru. Pamusoro pezvo, kushandiswa kwekuzviboorera pachezvako zvibatiso zveanchor mumamiriro ejoloji angangoita kudonha ane zvakanakisa anchoring mhedzisiro. Izvi zvikonzero zvakakonzera kuwedzera kupararira kwekushandiswa kweself drilling hollow anchor rods. Self drilling hollow anchor rods inonyanya kushandiswa mune zvinotevera zviitiko:
1. Inoshandiswa se prestressed anchor rod: inoshandiswa muzviitiko zvakaita semateru, kuchera pasi pevhu, uye anti floating kutsiva tambo dzeanchor. Self drilling hollow anchor rods inodonhedzwa kusvika pakadzika hunodiwa, uye ipapo kupera grouting kunoitwa. Mushure mekusimba, kukakavara kunoshandiswa;
2. Inoshandiswa sema micropiles: Self drilling hollow anchor rods inogona kudonhedzwa uye grouted pasi kuti iite micropiles, inowanzoshandiswa mumhepo magetsi ekugadzira shongwe nheyo, nheyo dzeshongwe dzekutumira, nheyo dzekuvaka, kuchengetedza nheyo dzemadziro, nheyo dzemabhiriji, nezvimwewo;
3. Inoshandiswa pazvipikiri zvevhu: inowanzoshandiswa kutsigirwa kwemateru, kutsiva simbi yesimbi yakagadzika tsvimbo, uye inogonawo kushandiswa kune yakadzika nheyo gomba tsigiro yemateru;
4. Inoshandiswa kugadzira zvipikiri zvematombo: Mune mamwe materu ematombo kana tunnel dzine mamiriro ekunze akanyanya kana kuti majoini ekuzviboorera wega, maburi anchor rods anogona kushandiswa pakuboora uye kugadzira kubatanidza matombo ematombo pamwechete kuti agadzirise kugadzikana. Somuenzaniso, materu ematombo emigwagwa mikuru nenjanji angangodonha anogona kusimbiswa, uye mashedhi epombi echinyakare anogonawo kutsiviwa kuti asimbiswe pakuzaruka kwemugero wakasununguka;
5. Kusimbisa kwekutanga kana kutonga kwenjodzi. Sezvo nguva yekutsigira yepakutanga geotechnical rutsigiro system inowedzera, izvi zvigadziriso zvekutsigira zvinogona kusangana nemamwe matambudziko anoda kusimbiswa kana kurapwa, senge deformation yenzvimbo yepakutanga, kugadzika kwehwaro hwepakutanga, uye kusimudzwa kwenzira yemugwagwa. Self drilling hollow anchor rods inogona kushandiswa kudhiraivha mune yepakutanga materu, hwaro, kana nzira yemugwagwa, nezvimwewo, yekugadzira uye kubatanidzwa kweakatsemuka, kudzivirira kuitika kwenjodzi dze geological.
