R&D and application of water pressure test equipment for kilometer-level horizontal directional boreholes
摘要
Abstract
Traditional water pressure test equipment has many limitations in data collection and test operation,and it is difficult to meet the needs of high-precision projects.This paper introduces a set of water pressure test methods and equipment suitable for kilometer-level horizontal directional holes,which incorporates an advanced automatic collection system,integrates high-precision sensors and intelligent control modules,innovatively designs the water-stop plug structure.This set of equipment can directly measure the actual pressure of the test section excluding pipeline losses.It can also judge the sealing performance of the test section and improve the test reliability.The key parameters in the test process can be recorded in real-time,continuously and accurately,avoiding problems such as manual operation errors and untimely data collection.The design of the new water-stop plug reduces the accident rate.The supporting test method is optimized according to the characteristics of the intelligent complete set of equipment,realizing the automatic operation and efficient management of the test.According to the test data,the water level elevation of the test section in the horizontal hole of the water pressure test can be accurately calculated.Verified by practical engineering applications,this new type of water pressure test equipment and test method significantly improve the reliability and accuracy of test data,enhance the work efficiency,provide more scientific and accurate basic data for geological surveys and engineering designs in fields such as geotechnical engineering,water conservancy and hydropower engineering,which have important engineering application value and popularization significance.关键词
