Preloading vakum mungkin terlihat sederhana dalam konstruksi. Namun, kontrol yang buruk terhadap detail dapat dengan mudah menyebabkan masalah kualitas seperti tingkat vakum yang tidak cukup, settlement yang tidak memadai, kebocoran udara, dan pemadatan yang tidak merata, yang akan mempengaruhi penerimaan proyek.<\/p>\n\n\n\n

Sembilan Cacat Kualitas Paling Sering Terjadi dalam Konstruksi Preloading Vakum<\/strong><\/strong><\/p>\n\n\n\n

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

Penyebab: <\/strong>Membran penutup yang rusak, sambungan las yang lemah, kebocoran udara di batas saluran penutup dan jaringan pipa yang tersumbat. Solusi: <\/strong>Periksa membran secara menyeluruh untuk kerusakan dan lakukan pengelasan ulang untuk memperbaiki kebocoran. Padatkan saluran penutup dengan pemeliharaan kelembapan dan kendalikan secara ketat kualitas konstruksi dinding penutup untuk memastikan kedap udara. Bersihkan jaringan pipa drainase untuk menjaga kedap udara.<\/p>\n\n\n\n

Masalah 2: Settlement lokal yang tidak merata dan pemadatan diferensial<\/strong>\u00a0<\/h2>\n\n\n\n

Penyebab: <\/strong>Jarak antar drain vertikal prefabrikasi yang tidak merata, kedalaman penggerusan yang tidak konsisten, jaringan pipa lokal yang tersumbat, dan sifat tanah berlapis. Solusi: <\/strong>Kendalikan secara ketat posisi dan kedalaman drain, perbaiki jaringan pipa yang tersumbat, dan atur drain yang lebih rapat di zona lemah.<\/p>\n\n\n\n

Masalah 3: Menggelembung dan genangan pada membran penutup<\/strong> <\/h2>\n\n\n\n

Penyebab:<\/strong> Lokasi tidak merata, drainase yang buruk, dan tekanan negatif lokal yang tidak merata. Solusi: <\/strong>Lakukan pengurugan lokasi secara halus sebelumnya, optimalkan gradien drainase jaringan pipa, alirkan genangan di atas membran secara tepat waktu, dan perbaiki membran jika diperlukan.<\/p>\n\n\n\n

Masalah 4: Tarik kembali, pecah, atau deviasi drain vertikal prefabrikasi<\/strong><\/h2>\n\n\n\n

Penyebab:<\/strong> Operasi mesin pemasangan drain yang tidak tepat, tanah yang terlalu keras atau lembut, kecepatan konstruksi yang berlebihan. Solusi: <\/strong>Standarisasi operasi peralatan, kendalikan kecepatan penggerusan, dan ulang pengeboran di posisi yang tidak memenuhi syarat.<\/p>\n\n\n\n

Masalah 5: Konsumsi energi tinggi dan efisiensi rendah dari pompa vakum<\/strong>\u00a0<\/h2>\n\n\n\n

Penyebab: <\/strong>Tidak adanya pemisah air-gas, kebocoran udara di jaringan pipa, dan peralatan yang menua. Solusi: <\/strong>Lengkapi sistem pemisah air-gas untuk mengurangi kehilangan dari pencampuran air dan gas. Periksa peralatan secara rutin dan periksa titik kebocoran udara.<\/p>\n\n\n\n

Masalah 6: Penurunan pasca konstruksi yang berlebihan<\/strong><\/h2>\n\n\n\n

Penyebab: <\/strong>Durasi stabilisasi tekanan yang tidak cukup, penghentian operasi sebelum tingkat konsolidasi memenuhi persyaratan, tingkat vakum yang terus-menerus rendah. Solusi:<\/strong> Lakukan stabilisasi tekanan secara ketat sesuai dengan persyaratan desain. Hentikan operasi hanya ketika data stabil dan memenuhi standar.<\/p>\n\n\n\n

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

Penyebab: Pemuatan tekanan negatif yang terlalu cepat dan pembatasan tanah sekitar yang tidak cukup. Solusi: <\/strong>Naikkan tingkat vakum secara perlahan, terapkan beban secara bertahap dan perkuat pemantauan di sekitar.<\/p>\n\n\n\n

Masalah 8: Efek perbaikan yang buruk di tepi zona penguatan<\/strong>\u00a0<\/h2>\n\n\n\n

Penyebab:<\/strong> Segel batas yang tidak memadai dan penurunan tekanan negatif yang parah. Solusi:<\/strong> Perdalam dan perlebar parit segel, serta padatkan drainase vertikal prefabrikasi di batas-batas untuk mengkompensasi kehilangan tekanan negatif.<\/p>\n\n\n\n

Masalah 9: Penurunan konstruksi yang tidak cukup<\/strong>\u00a0<\/h2>\n\n\n\n

Penyebab: <\/strong>Jarak yang lebih lebar atau kedalaman drainase yang tidak cukup dari yang dirancang, tingkat vakum yang tidak memenuhi standar dan waktu beban yang tidak memadai. Solusi: <\/strong>Atur drainase vertikal prefabrikasi pada jarak dan kedalaman penggerusan yang dirancang. Bangun dinding penutup dan kain filter dengan benar, pertahankan parit segel dan membran untuk mencapai tingkat vakum yang dirancang. Lakukan beban berkelanjutan sesuai spesifikasi dan lakukan pelepasan beban hanya setelah memenuhi kriteria penerimaan.<\/p>\n\n\n\n
