Simulation test system for safety inspection of pipe gallery drainage system

Abstract

The invention provides a safety detection platform and a test method for a pipe rack affiliated drainage system. The platform comprises four constituent parts: a pipe rack bin drainage system model, awater flow input device, a water flow output device and a test system. The water flow input device is connected with a top entrance of the pipe rack bin drainage system model through a pipeline; thewater flow output device is connected with a top exit of the pipe rack bin drainage system model through a pipeline; the water flow output device outputs water flow into the water flow input device toform a circulating loop. The test systems are dispersed in the water input and output pipelines and the pipe rack drainage system model in a form of sensor, and finally all acquired signals are inputinto a data acquisition machine for information processing. The test system can simulate a test of displacement and operation state parameters of a submersible pump after water enters the pipe rack bin. The system has relatively high generality, the input water flow parameters are flexible and variable, the test result is visual and credible, and a strong basis can be provided for the design andoperation maintenance of the pipe rack drainage system.

Description

technical field [0001] The invention belongs to the field of safety testing of the drainage system of ancillary facilities of a pipe gallery, and specifically refers to a model test system and a test method for a drainage system in a pipe gallery cabin. Background technique [0002] The construction of the pipe gallery involves many aspects such as waterproof design, construction, and materials. Although in the construction design and construction stage of the underground pipe gallery, according to the concept of focusing on prevention, combining rigidity and softness, multiple lines of defense, adapting measures to local conditions, and comprehensive management, the waterproof design and construction of the project are carried out by combining drainage and blocking, but the underground pipe gallery The biggest problems, such as deformation joints, construction joints, and leakage of wall pipes, have not been completely resolved, and have plagued the construction and mainten...

Problems solved by technology

[0003] At present, scholars mostly use computational fluid dynamics software to simulate the drainage process of the drainage system. In most cases, the theory is based on an ideal model. The numerical simulation results are often not combined with the actual engineering, resulting in evaluation results that do not conform to the actual working conditions of the drainage system.
