In high-speed railway construction, concrete quality is directly related to the safety and durability of the structures. As a critical component of this infrastructure, high-speed railway concrete mixing plants must meet technical standards far exceeding those required for ordinary commercial concrete production (such as those defined by ASTM International or the American Concrete Institute). This article will provide an in-depth analysis of the four core technical requirements for high-speed railway Masana'antar haɗa siminti.
1. Ultimate Uniformity in High-Speed Railway Concrete Mixing Plants
Muhimman Alamu na Fasaha:
– Mafi ƙarancin lokacin haɗawa: ≥120 daƙiƙu
– Bukatun daidaito: Koyofishin ƙarfi na bambanci ≤5%
– Kulawar iya aiki: Asarar laka ≤20mm/h
Cikakken nazarin fasaha:
Tsarin haɗin siminti da ake amfani da shi a muhimman sassan tsarin dogo mai saurin gaske (kamar faranti na layin CRTS III, sandunan akwatin da aka ƙara ƙarfi, ginshiƙan gada, da sauransu) yana da rikitarwa, kuma yaduwar isasshen magungunan rage ruwa masu inganci da ƙananan haɗe-haɗe yana da matuƙar muhimmanci. Lokacin haɗawa na daƙiƙa 120 shi ne mafi ƙarancin iyaka da aka tabbatar ta hanyar kwaikwayon motsin ruwa da gwaje-gwaje masu yawa, yana tabbatar da:
– Cika danshi a ƙwayoyin siminti da daidaitaccen martanin haɗewar ruwa
– Rarraba daidai na kwayoyin maganin rage ruwa a cikin tsarin
– Samuwar tsari mai dorewa na tsarin kumfa-ƙanana
– Cire warewa da zubar jini gaba ɗaya
II. Tsarin Auna Daidai: Babban Ci Gaban Fasaha a Cikakken Sarrafa Daidaito Mai Motsi
Jadawalin Kwatantrawa na Ka'idar Daidaito:
Rukuni na Kayan Aiki Ka'idar Jirgin ƙasa mai sauri (kuskure mai motsi) Ka'idar Kasuwanci Gabaɗaya (kuskure mara motsi) Kalubalen Fasaha
Yashi da ƙananan duwatsu ≤±2% ≤±2% Babban bambance-bambancen gudun kwararar kayan yana sanya sarrafa motsi ya zama da wahala
Kayan siminti ≤±1% ≤±1% mannewar foda, ragowar, da rashin aiki suna shafar daidaiton motsi
Haɗaɗɗiyar Ruwa ≤±1% ≤±1% Raguwar matsin lamba a bututun yana shafar daidaiton motsi
Sinadaran ƙari ≤±1% ≤±1% Matsanancin laka da ƙaramin ƙima suna sanya sarrafa motsi ya zama da wahala
Muhimman abubuwa game da Fasahar Daidaito Mai Motsi:
Sarrafa daidaito mai motsi muhimmin alama ce don auna matakin fasaha na masana'antar haɗawa. Ba kamar daidaito na tsaye ba, daidaito mai motsi yana nuna:
– Dorewar tsarin ciyarwa yayin aiki ba tare da tsayawa ba
– Ƙarfin amsa na na'urar gano abubuwa a ainihin lokaci (yawan ɗaukar samfur ≥ 100Hz)
– Algorithms na tsarin sarrafawa na ci gaba (sarrafawar PID mai daidaitawa)
– Tsarin hana tsangwama na tsarin inji
III. Cika dijitalizashin dukkan tsari: bin diddigin inganci da tsarin gargadi na farko mai hankali
Tsarin haɗin bayanai:
Matakin tattara bayanai na ainihin lokaci
– Cikakken bayanan samarwa na kowace gaurayawar siminti
– Kula da yanayin aiki na kayan aiki
– Kula da yanayin muhalli (zazzabi, danshi)
2. Matakin Sarrafa Gajimare
– Binciken manyan bayanai da hasashen yanayi
– Ganewar hankali ta tsarin alamu marasa al'ada
– Samarda rahoton inganci mai fannoni da dama
3. Matakin Hulɗar Aikace-aikace
– Nuna ainihin lokaci a cibiyar sa ido ta mai shi
– Isar da bayanin gargaɗi na wayar hannu
– Raba bayanai da raka'o'in sa ido
Tsarin Gargaɗin Farko Mai Hankali:
– Gargaɗi Mataki na 1 (Karkacewar Ma'auni): faɗakarwa na ji da na gani, sa ido ba tare da tsayawa ba
– Gargaɗi Mataki na 2 (Barnatarwar Yanayi): Sanarwar SMS, tsoma baki na hannu
– Gargaɗi Mataki na 3 (Matsananciyar Keta): Rufe kai tsaye, bin diddigin inganci
IV. Dorewar Kayan Albarkatu: Gudanarwa ta Gabatarwa na Sarrafa Tushen
Takaddun Fasaha na Tsufa na Siminti:
– Sarrafa Zazzabi: Zazzabin Shigarwa ≤ 60°C
– Lokacin tsufa: ≥ awanni 72
– Ingantattun Ayyuka:
– An rage zafin kololuwar dumama jiki da 15–20%
– An rage raguwa ta farko da 25–30%
– An inganta dacewa sosai da sinadaran haɗawa
Fasahar daidaita adadin danshi a cikin haɗin yashi da ƙananan duwatsu:
– Ka'idojin ajiya: Ajiya bisa yankuna, wanda aka shigo da shi na farko, shi ne ke fita na farko
– Lokacin daidaitawa: ≥ awanni 72
– Algorithm na Rage Ruwa: Daidaitawa ta atomatik bisa ga adadin danshi a ainihin lokaci
Kimar Fasaha: Ta hanyar tsauraran matakan sarrafa kayan albarkatu tun farko, an cimma abubuwa masu zuwa:
– An inganta daidaiton sarrafa rabo na ruwa da siminti zuwa ±0.01
An rage karkatar ma'auni na ƙarfin siminti zuwa ƙasa da 1.5 MPa.
– Alamar ɗorewa (ƙimar yaduwar ion na chloride) an inganta ta da 30%
