Projek penambahbaikan tanah lembut di tapak bergantung sepenuhnya kepada aliran kerja yang berstandard. Dokumen ini menyusun urutan pembinaan lengkap bagi prapemampatan vakum, merangkumi persediaan pra-binaan sehingga penerimaan selesai. Ia berfungsi sebagai rujukan praktikal untuk kakitangan teknikal dan pengurusan pembinaan.<\/p>\n\n\n\n

Urutan Pembinaan Keseluruhan:<\/strong> <\/p>\n\n\n\n

Pembersihan tapak dan perlevelan \u2192 Pengukuran dan penandaan \u2192 Pemasangan saluran menegak pra-fabrikasi \u2192 Pembinaan rangkaian saliran mendatar \u2192 Pembinaan sistem penutup \u2192 Pemasangan dan pengujian peralatan \u2192 Pam vakum dan penstabilan tekanan \u2192 Pemantauan proses penuh \u2192 Pembongkaran dan penerimaan<\/p>\n\n\n\n

Langkah 1: Pembersihan Tapak dan Perlevelan<\/strong> <\/p>\n\n\n\n

Buang rumpai, lumpur dan sisa binaan dari tapak. Perlevelkan tanah dan hapuskan ketulan dan lekukan. Elakkan objek tajam menusuk membran penutup dan sediakan asas yang rata untuk operasi seterusnya.<\/p>\n\n\n\n

Langkah 2: Pengukuran dan Penandaan<\/strong>\u00a0<\/p>\n\n\n\n

Lakukan susun atur tepat mengikut lukisan reka bentuk. Tandakan kedudukan pemasangan saluran menegak pra-fabrikasi, laluan paip saliran dan sempadan zon penambahbaikan. Tetapkan penanda yang jelas untuk memastikan jarak dan kedalaman mematuhi spesifikasi reka bentuk.<\/p>\n\n\n\n

Langkah 3: Pemasangan Saluran Menegak Pra-fabrikasi<\/strong> <\/p>\n\n\n\n

Gunakan mesin pemasang saluran khas untuk penempatan dan pemasangan. Kawal ketat kedalaman pemasangan, kecondongan dan jarak. Elakkan penarikan semula saluran, keretakan dan ketidaksejajaran. Potong dan pasang saluran selepas selesai untuk memastikan saluran saliran tidak tersekat.<\/p>\n\n\n\n

Langkah 4: Pembinaan Rangkaian Saliran Mendatar<\/strong> <\/p>\n\n\n\n

Pasang hos penapis fleksibel dan rangkaian paip utama-cawangan. Sambungkan saluran menegak kepada paip cawangan dengan tepat. Susun atur paip secara sekata dengan cerun yang munasabah, bebas dari simpulan dan penyumbatan untuk membentuk sistem saliran yang bersambung sepenuhnya.<\/p>\n\n\n\n

Langkah 5: Pembinaan Sistem Penutup<\/strong> <\/p>\n\n\n\n

Pasang geotekstil asas untuk melindungi sistem saliran, diikuti oleh membran penutup berlapis-lapis. Lembaran sambungan membran dipatri dengan kukuh menggunakan fusi termal. Selitkan tepi membran ke dalam parit penutup dan padatkan untuk penutupan rapat bagi menghapuskan titik kebocoran udara.<\/p>\n\n\n\n

Langkah 6: Pemasangan dan Pengujian Peralatan<\/strong> <\/p>\n\n\n\n

Pasang pam vakum, pemisah air-gas dan instrumen pemantauan. Sambungkan sistem paip dan periksa secara menyeluruh litar dan prestasi penutup. Lakukan pengujian tanpa beban untuk mengesahkan operasi peralatan yang normal.<\/p>\n\n\n\n

Langkah 7: Pam vakum berterusan dan penstabilan tekanan<\/strong> <\/p>\n\n\n\n

Mulakan pam vakum rasmi dan tingkatkan tekanan vakum secara beransur-ansur. Kekalkan tekanan negatif yang stabil melebihi 80\u202fkPa dengan operasi berterusan; elakkan penutupan secara sewenang-wenangnya. Ambil langkah perlindungan tapak yang sesuai.<\/p>\n\n\n\n

Langkah 8: Pemantauan dan Kawalan Proses Penuh<\/strong>\u00a0<\/p>\n\n\n\n

Pantau secara berterusan tekanan vakum di bawah membran, penempatan permukaan, tekanan air pori dan pergeseran tanah mendatar. Catat data harian dan laraskan keadaan pembinaan berdasarkan hasil pemantauan.<\/p>\n\n\n\n

Langkah 9: Pengosongan dan Penerimaan<\/strong> <\/p>\n\n\n\n

Kosongkan dan matikan peralatan apabila tahap penggabungan, penempatan dan kapasiti beban memenuhi keperluan reka bentuk dan kekal stabil selama lebih dari tujuh hari. Keluarkan fasiliti, susun dokumen dan lengkapkan penerimaan selesai.<\/p>\n\n\n\n

Kesimpulan<\/strong> <\/p>\n\n\n\n

Pengisian vakum adalah teknik utama untuk penambahbaikan tanah lembut kawasan yang luas. Setiap prosedur kerja secara langsung menentukan prestasi pengukuhan. Pelaksanaan ketat aliran kerja piawai dan kawalan ketat terhadap pengaliran, penutupan, pam vakum dan pemantauan dapat mengurangkan risiko kualiti secara berkesan dan memastikan pengukuhan tanah lembut memenuhi jangkaan reka bentuk.<\/p>\n\n\n\n
