Description

A kind of device and method for tiltedly boring formula acquisition small water bed mud in bank
Technical field
The present invention relates to soil environment monitoring fields, and in particular to it is a kind of bank tiltedly bore formula acquisition Sediments device and Method.
Background technique
The system protection of scenery with hills and waters Tianlin County lake grass and reparation have become government action guide and whole society's common recognition.It is protected in system In shield and repair process, soil is important protection and repairs object, and soil quality is the important finger of Eco-Environmental Synthetic Analyses Mark.Therefore, in National land space restoration of the ecosystem, ECOLOGICAL ENVIRONMENTAL MONITORING, farmland construction evaluation, Geological environment treatment, water pollution control In the process, acquisition pedotheque necessitates program.According to the opposite occurrence status of soil and water body, land can be divided into Soil under soil and water body.Wherein, the pedotheque of land can directly take, more convenient.In contrast, due to water Body covering, bed mud are soft, and the acquisition of soil (Sediments) is then more difficult in water body.
Sediments are acquired, mainly there is acquisition, contactless device acquisition after acquisition of manually paddling, draining drainage.Preceding two It is big that kind method needs manpower and time cost to expend, and in practical soil monitoring, contactless device is mostly used to acquire bed mud.This In a little equipment, there is a device that bed mud is extracted based on piston principle, e.g., a kind of column for acquiring shallow Sediments adopts mud dress It sets, Authorization Notice No. CN203811422U;A kind of device and its acquisition method acquiring Sediments undisturbed, application publication number CN107817124A.Besides the device that soil is freezed and lifted under water body, e.g., a kind of sampling wild water sediment side Method and its device, application publication number CN102445363A.Besides grab type vertically grabs the device of bed mud, and e.g., box depth Water-bed mud stratified sampler, Authorization Notice No. CN203824800U.
These types of equipment has in common that they are vertical types, that is, is all that sample devices hangs down when sampling The straight water surface is put into water body, acquires bed mud.This requires utilize boat-carrying, mechanical assist device when acquiring Sediments Sampling apparatus is sent to above sampled point and is sampled.However, for small water, such as stream, water channel, farmland, swag Deng, water body, small and poor connectivity, is unfavorable for the entrance and transition of ship, mechanical assist device, is just difficult to realize Sediments Vertical type sampling.Therefore, the sampling of small water bed mud becomes technical problem.
Technical solution
In view of the above-mentioned problems, the present invention is intended to provide a kind of bank tiltedly bore formula acquisition small water bed mud device and method, Overcome the problems, such as that vertical type sampling apparatus is difficult to carry out during small water substrate sludge sampling, provide it is a kind of it is simple and feasible, The effectively device and operating method of acquisition small water bed mud.
