The invention provides an undisturbed soil column sampler for salt marsh wetland, which comprises a storage pipe, a lifting rod, a reciprocating plug, a rubber plug, a steel ring and a fixing device; the inside of the storage pipe is provided with a reciprocating plug, which is fixedly connected with the front end of the lifting rod, a rubber plug is arranged at the upper end of the storage pipe, and a rubber plug is provided at the middle part of the rubber plug. A ventilation hole is arranged on the rubber plug when the lifting rod moves up and down, a fixing device is arranged on the upper part of the rubber plug on the lifting rod, a steel ring is also arranged on the outer wall of the upper end of the storage pipe, the steel ring is fixed by two and a half rings through screws, and the outer side of the steel ring is symmetrically arranged with a handle; the lower end of the storage pipe is a sampling port, and a ring is arranged at the sampling port. Shape cutter or sample cover. The sampler has the following beneficial effects: the sample is taken out by the vacuum state formed between the reciprocating plug and the sample, the sampling depth and the sampling diameter exceed the existing sampler; the sample is less compacted during the sampling process, the sample has good authenticity and integrity, high cleanliness, and can more truly reflect the geology.

盐沼湿地的未扰动土壤柱样取样器
本专利技术涉及盐沼湿地地质调查与研究
,具体涉及一种盐沼湿地的未扰动土壤柱样取样器。
技术介绍
沉积物0-100cm深度是盐沼湿地演化发育的重要地层,对该深度的盐沼湿地土壤取样非常必要。盐沼湿地常被芦苇等典型盐沼湿地植被覆盖,并且植被密度大,芦苇根在土壤近表面形成一层结实的须根层,现有的取样器穿透该层困难。盐沼湿地比较松软,现有的取样器容易造成样品深度失真。另外,现有的取样器里面的土壤样品后期获得是通过用切割机切开取样器后取出样品,切割机刀片极易与土壤样品接触,并切割的取样器会产生粉末,都在一定程度上污染了土壤样品,不利于后期工作的开展。对于地质取样,一次获取的样品越多,测试分析参数越多,取样深度越深,研究的年代越久远,越有利于科学研究,这就要求一次取样过程中可能取到更多的样品,更深的样品。现有的取样器一般靠土壤的粘性和与取样器之间的摩擦力将样品带出,对于柱状样品来说,土壤体积越大,自重越大,靠土壤的粘性和与取样器之间的摩擦力无法取到较深的样品,因此,现有的取样器的取样深度较浅,取样直径较小。沉积物0-100cm深度是盐沼湿地演化发育的重要地层,对该深度的盐沼湿地土壤取样非常必要。目前还没有一种有效的取样工具能快速有效的取得0-100cm盐沼湿地的未扰动土壤样品。
技术实现思路
本专利技术的目的在于针对现有土壤取样器取样深度较浅,取样直径较小的问题,提供一种用于盐沼湿地的未扰动土壤柱样取样器,取样深度可达120cm,样品直径可达10cm,特别适合盐沼湿地0-100cm深度取样。本专利技术是采用以下的技术方案实现的:一种盐沼 ...
