Integrated inspection well for monitoring flow of urban drainage pipeline and detection method

Abstract

The invention discloses an integrated inspection well for urban drainage pipeline flow monitoring and a detection method. The integrated inspection well comprises a vertical shaft, and a buried drainage pipeline is arranged at the bottom of the vertical shaft; a telescopic rod is hinged to the top of the inner wall of the buried drainage pipeline, a flowmeter fixing base is hinged to the end of the telescopic rod, hinged shafts at the two ends of the telescopic rod are both in the horizontal direction and are both perpendicular to the axis of the buried drainage pipeline, and a flowmeter is detachably installed on the flowmeter fixing base. The detection method comprises the following steps of telescopic rod adjustment, flowmeter installation, height adjustment, installation and debugging, detection and the like. The method has the advantage that the accuracy of the flow monitoring data can be improved. Even under the condition that the well chamber of an existing drainage inspection well is complex in condition, the flowmeter can be installed at the preset position, the problems that the flowmeter of the existing drainage inspection well is difficult to install and the flowmeter cannot be installed at the preset position in a traditional supporting rod installation mode are solved, the flow measurement precision is improved, and the measurement result is more accurate.

Description

technical field [0001] The invention relates to the field of flow monitoring of urban drainage pipes, in particular to an integrated inspection well and a detection method for flow monitoring of urban drainage pipes. Background technique [0002] With the increasing development of smart drainage pipe network projects, in order to grasp the operation of urban drainage pipe network, it is necessary to monitor the flow of drainage pipes in real time. Flow monitoring data can provide important information for drainage system management personnel to make decisions. For example, based on the monitored flow and liquid level information, problems such as rain and sewage mixing and external water inflow and infiltration can be diagnosed. In recent years, due to heavy rainfall or continuous rainfall, the urban drainage system is overloaded, resulting in waterlogging and waterlogging disasters in the city. By installing flowmeters in the drainage pipes, it is possible to know the hydra...
