Tekinoroji yekuvaka yerefu spiral yakafinhwa murwi

1. Yakareba spiral drilled cast-in-place mirwi kazhinji inoshandisa superfluid kongiri, ine kuyerera kwakanaka. Matombo anogona kumira mukrete pasina kunyura, uye hapazovi nekusarura. Zviri nyore kuiisa mucheji yesimbi; (Superfluid kongiri inoreva kongiri ine kudonha kwe20-25cm)

2. Murwi muromo hauna ivhu rakasununguka, kudzivirira matambudziko akajairika ekuvaka akadai sekuputsika kwemurwi, kuderedzwa kwedhayamita, uye kudonha kwegomba, uye kuve nechokwadi chekuvaka mhando nyore;

3. Kugona kwakasimba kupinda muzvikamu zvevhu rakaoma, kukwirira kwemurwi mumwe chete kubereka, kugona kwekuvaka kwakanyanya, uye kushanda kuri nyore;

4. Ruzha rwakaderera, hapana kuvhiringidza kuvagari, hapana chikonzero chekudzivirirwa kwedhaka rusvingo, hapana kuburitsa kusvibisa, hapana kusvinwa ivhu, uye nzvimbo yekuvaka yakabudirira;

5. Yakakwirira yakazara mabhenefiti uye yakaderera mari yeinjiniya zvichienzaniswa nemamwe marudzi emirwi.

6. Kuverengera kwekugadzira kweiyi nzira yekuvaka kunotora nzira yakaoma yekuchera uye grouting murwi wekugadzira, uye iyo dhizaini kuverenga indekisi inofanira kutora iyo yakaoma yekuchera uye grouting pile index (iyo index kukosha yakakura kupfuura iyo yedhaka inochengetedza madziro kuchera uye zvishoma. kupfuura iyo yemurwi wakagadzirwa).

2. Chikamu chekushandisa:

Inokodzera kuvaka mirwi yenheyo, makomba ehwaro, uye yakadzika tsime tsigiro, inokodzera kuzadza maseru, silt layer, jecha layer, uye gravel layers, pamwe neakasiyana ivhu akaturikidzana nemvura yepasi. Inogona kushandiswa kugadzira mirwi mumamiriro ezvinhu akashata akadai semavhu akapfava evhu uye machira ejecha. Murwi dhayamita kazhinji pakati 500mm uye 800mm.

3, Maitiro musimboti:

Long spiral drilling pile imhando yemurwi unoshandisa refu spiral drilling rig kuboora maburi kusvika pakakwirira dhizaini. Mushure mekumisa kuchera, buri rekongiri papiipi yemukati yekubooresa inoshandiswa kubaya superfluid kongiri. Mushure mekubaya jekiseni kune dhizaini murwi wekumusoro, tsvimbo inobviswa kudzvanya keji yesimbi mumurwi wemuviri. Pakudira kongiri kumusoro kwemurwi, kongiri yakadirwa inofanira kudarika pamusoro pemurwi ne50cm kuti ive nechokwadi chekusimba kwekongiri kumusoro kwemurwi.
