\"VacuumPreloading\"<\/figure>\n\n\n\n

Preloading vakum mungkin kelihatan mudah dalam pembinaan. Walau bagaimanapun, kawalan yang lemah terhadap butiran boleh dengan mudah menyebabkan isu kualiti seperti tahap vakum yang tidak mencukupi, penempatan semula yang tidak mencukupi, kebocoran udara dan pemadatan yang tidak sekata, yang akan menjejaskan penerimaan projek.<\/p>\n\n\n\n

Sembilan Kecacatan Kualiti Paling Kerap dalam Pembinaan Preloading Vakum<\/strong><\/strong><\/p>\n\n\n\n

Masalah 1: Tahap vakum yang rendah atau tidak stabil di bawah membran\u00a0<\/strong><\/h2>\n\n\n\n

Punca: <\/strong>Membran penutup yang rosak, sambungan kimpalan yang lemah, kebocoran udara di sempadan parit penutup dan rangkaian paip yang tersumbat. Penyelesaian: <\/strong>Periksa membran secara menyeluruh untuk kerosakan dan kimpal semula untuk membaiki kebocoran. Padatkan parit penutup dengan penyelenggaraan kelembapan dan kawal ketat kualiti pembinaan dinding penutup untuk memastikan ketat. Bersihkan rangkaian paip saliran untuk mengekalkan kedap udara.<\/p>\n\n\n\n

Masalah 2: Penempatan semula tempatan yang tidak sekata dan pemadatan berbeza-beza<\/strong>\u00a0<\/h2>\n\n\n\n

Punca: <\/strong>Jarak yang tidak sekata antara saluran vertikal pra-fabrikasi, kedalaman pemanduan yang tidak konsisten, rangkaian paip tempatan yang tersumbat dan sifat tanah berlapis. Penyelesaian: <\/strong>Kawal ketat kedudukan dan kedalaman saluran, baiki rangkaian paip yang tersumbat, dan susun saluran yang lebih padat di zon lemah.<\/p>\n\n\n\n

Masalah 3: Pembengkakan dan kolam air pada membran penutup<\/strong> <\/h2>\n\n\n\n

Punca:<\/strong> Tapak tidak sekata, pengaliran air yang lemah dan tekanan negatif tempatan yang tidak sekata. Penyelesaian: <\/strong>Lakukan pelapisan tapak yang halus terlebih dahulu, optimakan kecerunan saluran paip, salurkan kolam air pada membran tepat pada masanya, dan baiki membran jika perlu.<\/p>\n\n\n\n

Masalah 4: Tarikan balik, pecah atau deviasi saluran vertikal pra-fabrikasi<\/strong><\/h2>\n\n\n\n

Punca:<\/strong> Pengendalian mesin pemasukan saluran yang tidak betul, tanah yang terlalu keras atau lembut, kelajuan pembinaan yang berlebihan. Penyelesaian: <\/strong>Standardkan pengendalian peralatan, kawal kelajuan pemanduan, dan ulang pembuatan di tempat yang tidak memenuhi syarat.<\/p>\n\n\n\n

Masalah 5: Penggunaan tenaga yang tinggi dan kecekapan rendah pam vakum<\/strong>\u00a0<\/h2>\n\n\n\n

Punca: <\/strong>Ketiadaan pengasing air-gas, kebocoran udara dalam rangkaian paip dan usia peralatan. Penyelesaian: <\/strong>Pasang sistem pengasing air-gas untuk mengurangkan kehilangan dari pencampuran air-gas. Periksa peralatan secara berkala dan semak titik kebocoran udara.<\/p>\n\n\n\n

Masalah 6: Penempatan selepas pembinaan yang berlebihan<\/strong><\/h2>\n\n\n\n

Punca: <\/strong>Tempoh penstabilan tekanan yang tidak mencukupi, penutupan mesin sebelum tahap pemadatan memenuhi keperluan, tahap vakum yang sentiasa rendah. Penyelesaian:<\/strong> Laksanakan penstabilan tekanan dengan ketat mengikut keperluan reka bentuk. Hentikan operasi hanya apabila data stabil dan memenuhi piawaian.<\/p>\n\n\n\n

Masalah 7: Perpindahan mendatar yang berlebihan<\/strong> <\/h2>\n\n\n\n

Punca: Bebanan tekanan negatif yang terlalu cepat dan kekurangan sekatan tanah sekeliling. Penyelesaian: <\/strong>Naikkan tahap vakum secara perlahan-lahan, berikan beban secara berperingkat dan tingkatkan pemantauan sekeliling.<\/p>\n\n\n\n

Masalah 8: Kesan penambahbaikan yang lemah di tepi zon pengukuhan<\/strong>\u00a0<\/h2>\n\n\n\n

Punca:<\/strong> Pengedap sempadan yang tidak mencukupi dan penurunan tekanan negatif yang teruk. Penyelesaian:<\/strong> Perdalam dan lebarkan parit pengedap, dan padatkan saluran menegak pra-fabrikasi di sempadan dengan betul untuk menggantikan kehilangan tekanan negatif.<\/p>\n\n\n\n

Masalah 9: Penempatan selepas pembinaan yang tidak mencukupi<\/strong>\u00a0<\/h2>\n\n\n\n

Punca: <\/strong>Jarak yang lebih luas atau kedalaman saluran yang tidak mencukupi berbanding reka bentuk, tahap vakum yang tidak memenuhi piawaian dan masa beban berterusan yang tidak mencukupi. Penyelesaian: <\/strong>Susun saluran menegak pra-fabrikasi pada jarak yang direka dan kedalaman pemanduan. Bangunkan dinding pengedap dan fabrik penapis dengan betul, kekalkan parit pengedap dan membran untuk mencapai tahap vakum yang direka. Laksanakan beban berterusan seperti yang ditetapkan dan lakukan pelepasan hanya selepas memenuhi kriteria penerimaan.<\/p>\n\n\n\n
