Example Embodiment

[0089] Example 1: Combining Figure 1 to Figure 3 Illustrating this embodiment, the pipeline 100 to be tested provided in this embodiment, that is, the inner diameter of the reinforced concrete pipeline is set to 1.5m, the pipe length is set to 3m, and the corrosion solution is 5% dilute sulfuric acid. The movable adjustment detection platform 3 has a bearing side length of 0.8m and a bearing mass of 150kg. The height of the first adjustment bracket 321 and the second adjustment bracket 322 can be adjusted in a range of 0.3-0.8m, and the adjustment rod 313 can be adjusted in a range of 0-3m. The reinforced concrete pipe is lying on the support bearing of the wooden pile, and the corrosion solution gathers the lower part of the reinforced concrete pipe. The two-end blocking device 1 is fixed on both ends of the reinforced concrete pipeline by blocking plates 11 and bolts, and a corrosion-resistant rubber ring with a width of 4 mm is pasted in the middle for sealing.

Example Embodiment

[0090] Example 2: Combination figure 1 and figure 2 Describing this embodiment, in the present invention, the movable detection platform is installed on the movable slide rail 311 through the movable pulley 314, and the adjustable rod 313 can be pushed to change the measurement position of the movable detection platform 3 in different sections of the reinforced concrete pipeline, and the first adjustment bracket can be adjusted. The height of 321 and the second adjusting bracket 322 can be changed and the height of the test platform 3 can be adjusted and moved, and a guardrail 315 is provided around the test table 312 to ensure the safe operation space of personnel and equipment.

Example Embodiment

[0091] Embodiment 3: After the sulfuric acid / sulfate corrosion is completed, the sulfuric acid corrosion solution in the reinforced concrete pipeline can be emptied through the corrosion solution circulation device 2, and after dredging and cleaning, the corrosion characteristics of the inner wall of the corrosion solution circulation device 2 are tested in turn. and residual mechanical properties.

[0092]According to the above method, the corrosion status of the corroded pipeline can be detected and monitored at the same time during the corrosion process, the continuity of the internal corrosion status of the reinforced concrete can be ensured, and the safety distance between the personnel and the corrosion layer and corrosion products can be ensured during the test process. To ensure the safety of personnel, it is feasible and safe to use sulfuric acid / sulfate and other precursor chemicals for corrosion and life cycle monitoring of large-diameter reinforced concrete pipeline...

Abstract

The invention provides an auxiliary detection system and detection method for a drainage pipeline in a corrosive environment, and belongs to the technical field of pipeline detection. The corrosion solution circulating device is used for being connected with a to-be-detected pipeline and filling the to-be-detected pipeline with a corrosion solution to form a corrosion environment in the to-be-detected pipeline; and the movable adjusting detection platform is located in the to-be-detected pipeline and can move along the to-be-detected pipeline in at least three dimensions to detect the to-be-detected pipeline. According to the embodiment of the invention, the real-time detection of the pipeline condition in the corrosion environment is realized, the detection dimensions are multiple, the comprehensive detection of each dimension of the pipeline can be realized, the accuracy and authenticity of the detected and acquired data are ensured, the input and output times of the corrosion solution can be reduced, and the detection efficiency is improved. And a test scheme for the residual performance and the life cycle of the pipeline in the corrosion environment has feasibility and continuity.

Description

technical field [0001] The invention relates to the technical field of pipeline detection, in particular to an auxiliary detection system and detection method for drainage pipelines in a corrosive environment. Background technique [0002] As an important part of the municipal infrastructure, the urban drainage network has the functions of collecting, transporting and discharging rainwater and sewage. It is the underground lifeline of the city and is closely related to the safety of the city and the living environment. However, due to the systematic and complex characteristics of the pipe network, coupled with the long history of the urban drainage pipe network, harsh environment, intricate and long service time, etc., the problems of aging and corrosion of the pipe network are more prominent, and the structural attenuation and damage accumulation are serious. , directly affect the operation safety of the pipeline network, and even cause major accidents, resulting in casualt...
