Problems solved by technology
However, the sampling of sediments in urban sewage pipes is relatively poor in implementation. At present, the commonly used sampling method in China is manual downhole sampling. Due to the presence of H2S, CH4 and other dangerous gases in the sewage pipe network, the downhole sampling personnel need to carry out necessary protection work. Even so, this sampling method is also very dangerous, and the protection work is relatively cumbersome

Abstract
The invention relates to a city sewage pipeline sediment sampling apparatus, which comprises a lateral rod and a telescopic vertical rod, wherein the vertical rod and the telescopic lateral rod are connected by adopting a cylindrical pin, a traction rope is connected between the vertical rod and the lateral rod, and controls an angle of the lateral rod relative to the vertical rod, and the lower portion of the other end of the lateral rod relative to the cylindrical pin forms a wire connection with a trowel. According to the present invention, risk caused by the traditional artificial downhole mud sample sampling method and complexity of the preparatory measures are solved, it is completely ensured that operators perform sampling operations under a safe environment, the apparatus has characteristics of simple operation and simpleness, the sampled sediment sample has representativeness, and important significances are provided for operator safety protection and research of sewage pipeline network bottom mud formation and transformation.
Description
technical field [0001] The invention belongs to the technical field of sewage pipe network sampling, and relates to the sampling of sewage pipes, in particular to an urban sewage pipe sediment sampling device. Background technique [0002] After long-term operation of the urban sewage pipe network, due to long-term sedimentation, changes in water quality and quantity, unreasonable design, construction and other reasons, a relatively dense sediment layer will be formed at the bottom of the sewage pipe. The formation of sediment layer will reduce the water flow capacity of the sewage pipe network, leading to problems such as sewage overflow. At the same time, the heavy metals, nutrients and refractory organic matter enriched in the sediment layer will be released into the water phase when the conditions are suitable, causing the deterioration of the water quality in the pipe network, thereby affecting the normal operation of the downstream sewage treatment plant. Based on the...
