Hướng dẫn thi công và nghiệm thu hệ thống cấp thoát nước nhà cao tầng

Hướng dẫn thi công và nghiệm thu hệ thống cấp thoát nước nhà cao tầng • Phần 1: Giới thiệu chung về hệ thống cấp thoát nước trong nhà • Phần 2: Quy Trình thi công • Phần 3: Quy trình nghiệm thu hoàn công • Phần 4: Tiêu chuẩn nghiệm thu bàn giao, các bước nghiệm thu hoàn công • Phần 5: Các bài học kinh nghiệm HTCN tăng áp trực tiếp : có hoặc không có két nước Ưu điểm : Đơn giản, tiết kiệm chi phí đầu tư Nhược điểm : Hệ thống hoạt động không ổn định dễ xảy ra sự cố, không an toàn cho các thiết bị dùng nước, hạn chế chiều cao tầng lấy nước HTCN phân vùng (phổ biến hay dùng): Có bể chứa nước ngầm, trạm bơm, két nước và các hệ thống van giảm áp Ưu điểm : + Đảm bảo cấp nước đến mọi thiết bị ổn định và đủ áp + Đảm bảo kỹ thuật, dễ vận hành quản lý + Hạn chế máy bơm, tốn điện và người quản lý, giảm tiếng ồn do bơm + Kết hợp tốt mỹ quan kiến trúc ngôi nhà Nhược điểm : + Chi phí đầu tư cao
