Abstract
The invention relates to a novel method for measuring underground water flowing direction in the field of geological engineering, hydrological water resource, water resource protection and the like, in particular to a method and a device for multi-directionally collecting water samples. The method fixedly connects more than two water sample collectors capable of collecting water samples at the same specific depth to the periphery of a positioning block, and water sample collecting holes set by at least two water sample collectors in the water sample collectors fixed on the positioning block have different water inletting directions so as to collect the water samples in the different directions and at the specific depth. Therefore, through the technical proposal, the device and the method can effectively prevent the mixing of water samples at the non-specific depth in the process of putting the collector, and only collect the water samples at the specific depth and in different directions. In addition, the device for multi-directionally collecting the water samples has the characteristics of convenient carrying and use, flexible and reliable manual operation, difficult damage, smallvolume and the like.
Description
Technical field
The present invention relates to a kind of method and apparatus of multi-directionally collecting water samples, belong to technical fields such as Geological Engineering, underground water scientific and engineering, hydraulic engineering, hydrographic water resource, water environment protection.
Background technology
When carrying out the flow directional detection of water, can in water, drop into certain tracer agent, tracer agent is wandering downstream with flowing of water, makes the tracer concentration difference on the different directions in the water, can calculate the flow direction of water according to the tracer concentration on the different directions.
The water sample that will simply gather underground water surface or surface water body surface is very simple nothing the matter, but the water sample of gathering different directions on the following certain depth in ground water level or surface water body surface is just very difficult, because before collector is rendered to certain depth, be easy to sneak into the water on the nonspecific degree of depth, actual acquisition to be the mixed sample that comprises water on the different depth.
In the prior art, only occur gathering the collecting device that is regardless of the directivity water sample on certain degree of depth, as FFS_A type ground water fixed depth sampler and spring pressure-cliping device for fetching water from.
FFS_A type ground water fixed depth sampler is by the development of Chinese geologic examination research institute, and it is made up of collector, air bag and ground qi of chong channel ascending adversely and pumping equipment.2 air bags lay respectively at the top and bottom of collector, during use collector and 2 air bags are put into predetermined depth synchronously, qi of chong channel ascending adversely equipment by ground carries out qi of chong channel ascending adversely to air bag then, air bag is sticked out closely to be contacted with the wall of a borehole, the sneaking into of air bag upper and lower water in preventing to hole drawn water with the ground pumping equipment after isolating upper and lower water fully, thereby reaches the purpose of water sample on certain degree of depth of collection, the water sample that is collected is with regard to one, and is non-directional.This sampler complicated operation difficulty, efficient is very low, poor reliability, and can only in boring, use.
Spring pressure-cliping device for fetching water from is to design before 2006, and it is constituted jointly by internal diameter less upper shell and the bigger lower shell of internal diameter, and lower shell is made up of inverted cone surface, sealing through hole, steel ball and the depression bar that can move up and down in cylindrical shell again.Depression bar also passes through nut, the loose connection of nut by upper straight rod and following straight-bar.Be provided with carrying handle type activity card article, draw-in groove, cavity etc. in the upper shell.This sampler structure is complicated, unstable properties, and the degree of depth that can get is limited, generally can not surpass the 50m degree of depth.
Therefore, for now, also there are not multidirectional water sampling device of a kind of special use or method, can prevent to sneak in the collector launch process water sample on the nonspecific degree of depth, and only gather on the certain depth and the different directions water sample, and this has greatly limited to the scientific technological advance in the relevant water body research field, is a big technical barrier of being badly in need of solution in this area.
Summary of the invention
