Ongororo yeMakomba ekuchera ePrecast Piles uye Drill Pipe dzeCast-In-Place Piles -1

Zvinoenderana nenzira dzakasiyana dzekuvaka, mirwi inogona kukamurwa kuita precast mirwi (prestressed pombi mirwi) uye yakakandwa-mu-nzvimbo mirwi (drill-pipe cast-in-place piles). Ose ari maviri anoshandiswa zvakanyanya muvhu rakapfava nheyo uye yakadzika-yakavigwa nheyo. Ivo vane hunhu hwekubereka kwepamusoro, kugadzikana kwakanaka, diki pekugara, uye kushomeka kwekushandisa kwezvinhu uye vanogona kunyatsosangana nesimba rechivako, deformation, uye kugadzikana. Iwo marudzi maviri emapiru ane hunhu hwawo, nzira dzekuvaka dzakasiyana, midziyo yemuchina yakasiyana, uye hunyanzvi hwekuvaka. Mashandisirwo azvo uye mashandisirwo azvo zvinosiyaniswa. Ichi chinyorwa chichaenzanisa aya marudzi maviri emapitu uye kuongorora zvakanakira, zvazvakaipira, uye mashandisiro azvo kuti zvione kana kusarudza prestressed pombi mirwi kana kufinhwa.

Prestressed pombi murwi ihollow pombi muviri mutete kongiri prefabricated chikamu chakagadzirwa pre-tensioning tekinoroji, high-speed centrifugal steam kuporesa nzira yekuumba nekuwedzera yakanyanya-inoshanda yekudzikisa mvura. Iyo inonyanya kuumbwa necylindrical murwi muviri, endplate, uye simbi hoop.

Murwi wakafinhwa murwi wakagadzirwa nekuboora gomba panzvimbo yeinjiniya, kuchera gomba panotsemuka ivhu, kuisa furemu yesimbi mugomba remurwi, uye ipapo kudira kongiri mumurwi.

Iyo prestressed pombi mirwi uye kufinhwa mirwi inofananidzwa uye kuongororwa kubva pamaonero emuchina, mamiriro ekuvaka, tekinoroji yekuvaka, uye mutengo wekuvaka.

Mechanism

Prestressed pombi mirwi inogona kusvika pahudzamu hunodiwa neku drill pombi pressure. Munguva yekuunganidza, ivhu rakatenderedza muviri wemurwi rinosvinwa kunze, zvichikonzera kuporesa kwemvura yepore, kusimudza, uye kudzvanywa kwepashure munguva pfupi. Muvhu, kushushikana kuchakanganisa chiyero chezvivakwa zviripo, zviri mukati uye deformation yemigwagwa. Panguva imwecheteyo, inosvina murwi wekuvaka wakapedzwa kuti iite kukukurwa nekuyangarara.

Drill pombi yakaboora mirwi inogadzirwa neyakaoma kana madhaka ekuchengetedza nzira. Munguva yekugadzirwa kwepore uye kuumbwa kwemirwi, mirwi yakakomberedza haina kusvina pavhu, uye haizokonzeri zvakanyanya kukwira kwemvura muvhu. Naizvozvo, kuvakwa kwemirwi hakuzokanganisa kuchengetedzwa kwezvivakwa zviri pedyo nemigwagwa. Naizvozvo, kana zvichienzaniswa neakadzvanyirirwa mapaipi epombi, mirwi yakabhowekana ine hunhu hwekusazunguzika, hapana compaction athari, uye kushomeka kwezvivakwa zvakatenderedza. Asi simba rekongiri uye kugona kwekutakura kwemuviri wemurwi zvakaderera uye kugadzirisa kwakakura.

Kana iwe uchifarira tungsten carbide rods uye uchida rumwe ruzivo uye ruzivo, unogona KUBATA NESU nerunhare kana tsamba kuruboshwe, kana kuti TUMUMA MAIL pazasi peji.
