Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0017] A method for measuring groundwater parameters in basic engineering based on pressure tracer. A pressurization hole and more than one tracer measurement hole are drilled on the target to be measured according to the measurement index requirements, and the drilled pressurization hole and tracer measurement The depth of the hole reaches or exceeds the bottom plate of the aquifer, then use the water injection pipe to apply pressure water to the pressurized hole, install a measuring tube with a pressure sensor in the tracer hole, and finally repeat the direction according to the requirements of the measurement item and measurement accuracy. The pressurized hole is filled with pressure water, and the measured pressure value in the measuring tube and its time parameters are sent to the corresponding calculation module of the computer for processing to ob...

Abstract

The method comprises: using the feature of the pressure, that is the pressure can be fast transferred in underground water continuous medium, and be rapidly sensed, and be easy to be measured, to form a seepage pressure field; wherein, the pressure is used as a tracer; a pressure sensor is used to sense the correlated relation between the increased / decreased amounts of the tracer and the stratum medium; making GRS positioning, wireless data transmission; automatically generating and controlling pressure source; seepage database integration; computer analysis, calculation and recognition in order to display the hydrogeology engineering construction element under different boundary condition.

Description

technical field [0001] The invention relates to a basic engineering measurement technology, in particular to a method and system for measuring groundwater parameters, in particular to a method and system for measuring groundwater parameters in basic engineering based on pressure tracing. Background technique [0002] As we all know, the measurement of hydrogeological parameters involves all aspects of underground engineering construction. As long as there is groundwater seepage, it will affect the stability and construction of foundation projects. How to ensure the design and construction of foundation engineering, the prevailing method is indoor sampling and field on-site measurement to obtain the permeability parameters of strata with different structures. At present, there are mainly three types of methods for measuring and using groundwater parameters in field foundation projects: one is the pumping test method, which involves drilling a large-caliber underground and se...
