Investigation of Faults and Effective Factors in Wastewater Systems Using CCTV Camera Data

Abstract

In wastewater systems, the different types of failures such as collapse, reverse slope, clogging, incorrect building connection, lubrication, cracks and so on occur. These failures are caused by different factors such as physical, operational and environmental factors. Failures that occur constantly in older systems, cause continuous maintenance and repair work in the street. The frequency of these failures increases the operating cost of the system and disrupts normal operating conditions. In this study, it is aimed to investigate the structural defects and the factors that cause them in wastewater systems based on closed circuit TV (CCTV) camera images. For this, the wastewater system serving in Yeşilyurt and Battalgazi districts, which are central districts of Malatya province, has been chosen as the application area. Factors such as pipe length, pipe slope, percentage of structural defect and occupancy rate exceeding that could cause deterioration in wastewater systems were determined and data of these factors were obtained by methods such as field studies, CCTV and project reading. When the field data is analyzed, if the pipe slope is low, sedimentation occurs in the line and the flow capacity decreases over time. As a result, according to the results given in the graph and the table, the quality of workmanship (manufacturing, bedding material, slope appropriate to the project), environmental effects (traffic), physical and hydraulic factors have been effective in increasing the structural defect rate.

CCTV Kamera Verileri Kullanılarak Atıksu Sistemlerinde Meydana Gelen Arızaların ve Etkili Faktörlerin İncelenmesi

Abstract

Atıksu sistemlerinde zamanla çökme, ters eğim, tıkanma, yanlış bina bağlantısı, yağlanma, çatlak vb. arızalar meydana gelmektedir. Bu arızalar, fiziksel, işletme ve çevresel gibi farklı faktörlere bağlı olarak oluşmaktadır. Özellikle eski sistemlerde sürekli meydana gelen arızalar sonucu sokakta sürekli bakım onarım çalışmalarının yapılmasına neden olmaktadır. Bu arızaların sıklığı sistemin işletme maliyetini arttırmakta ve normal işletme koşullarını bozmaktadır. Bu çalışmada, atıksu sistemlerinde kapalı devre televizyon (CCTV) kamera görüntüleri esas alınarak tespit edilen yapısal kusurlar ve bunlara sebep olan faktörlerin incelenmesi amaçlanmıştır. Bunun için Malatya ili merkez ilçeleri olan Yeşilyurt ve Battalgazi ilçelerinde hizmet veren atıksu sistemi uygulama alanı olarak seçilmiştir. Atıksu sistemlerinde bozulmalara sebep olabilecek boru uzunluğu, boru eğimi, yapısal kusur yüzdesi ve doluluk oranı aşımı gibi faktörler belirlenmiş ve bu faktörlere ait veriler saha çalışmaları, kanal görüntüleme ve proje okuma gibi yöntemlerle elde edilmiştir. Saha verileri incelendiğinde, boru eğimi düşük olduğunda hat içinde çökelmeler oluşmakta ve akış kapasitesi zamanla düşmektedir. Sonuç olarak grafik ve Çizelgede verilen sonuçlara göre, yapısal kusur oranının artmasında, işçilik kalitesi (imalat, yatak malzemesi, projeye uygun eğim verilmesi), çevresel etkiler (trafik), fiziksel ve hidrolik faktörlerin etkili olduğu görülmüştür.
