Abstract

The invention relates to an amphibious soil profile gas in-situ collecting device, which comprises an outer protecting tube and an inner sampling tube which are made of polrvinyl chloride, wherein air vents are fully distributed on a wall of the outer protecting tube and a wall of the inner sampling tube; a waterproof and breathable film made of polyethylene is pasted on an outer wall of the inner sampling tube in a sealing way; a gauze is pasted outside the waterproof and breathable film; two ends of the outer protecting tube and the inner sampling tube are respectively sealed by adopting a first silicone plug and a second silicone plug with the middle part being provided with a gas conduit in a penetrating way; one end of the gas conduit is stretched into the middle part of the inner sampling tube; and the other end of the gas conduit is extended out of the outer protecting tube and is sealed by a third silicone plug. The device is simple and convenient to manufacture and use, is convenient to recover and utilize, has low cost, durability, good waterproofness, high air permeability and larger sample volume, is amphibious, can be applied in soil with high contents of rocky soil and sand grains, and can be used for effectively preventing a field installation process, plant roots and soil animals from damaging the device.

Description

The soil profile gas original-position collecting device that a kind of floods and droughts is dual-purpose
Technical field
The present invention relates to belong to the gas collecting apparatus field, be specifically related to the dual-purpose soil profile gas original-position collecting device of a kind of floods and droughts.
Background technology
Sampling pipe or silicone tube carry out the field installation in the general direct employing of existing soil profile gas original-position collecting device; Be prone to when not only having waterflooding that permeable ponding, air penetrability are low, gaseous diffusion stablize the shortcoming that required time is grown, the gas collecting amount is few; And suffer the destruction of installation process, root system of plant and soil toy easily, in the high soil of chisley soil or sand grain content, very easily damage.
Summary of the invention
Technical matters to be solved by this invention is: to the deficiency of above-mentioned prior art; A kind of good waterproof performance, the dual-purpose soil profile gas original-position collecting device of floods and droughts that air penetrability is high are provided, can effectively prevent open-air installation process, root system of plant and soil toy destruction device.
In order to solve the problems of the technologies described above, the technical scheme that the present invention adopted is: the soil profile gas original-position collecting device that a kind of floods and droughts is dual-purpose, and it comprises interior sampling pipe; Should expire air hole by interior sampling pipe wall cloth; Be characterized in: also comprise outer protection tube, the full air hole of this outer protection tube wall cloth, sealing of sampling pipe outer wall is pasted with waterproof ventilated membrane in this; This waterproof ventilated membrane is provided with gauze outward; An end that is somebody's turn to do outer protection tube and interior sampling pipe adopts the sealing of first silica gel plug, and the other end adopts middle second silica gel plug sealing that is equipped with gas conduit, and an end of this gas conduit stretches into interior sampling pipe middle part; The other end extends upward after stretching out outside the outer protection tube, and its port adopts the sealing of the 3rd silica gel plug.
Said waterproof ventilated membrane is processed by the high-molecular polythene material.Said gas conduit is processed by the PVC flexible pipe.Said gauze is 300 purpose nylon gauzes.
So, the waterproof ventilated membrane that this device adopts the high high-molecular polythene material of air penetrability to process guarantees air permeability and good simultaneously in waterproof; This waterproof ventilated membrane covers gauze outward can effectively prevent root system of plant and the soil toy destruction to waterproof ventilated membrane; Outer protection tube can also be protected interior sampling pipe effectively, and the scraping that receives sand grains in the soil with sampling pipe in preventing when mounted destroys.
This device making, easy to use, the convenient recycling, cost is low; Good waterproof performance, air penetrability height; Sampling amount is bigger, and fieldworthiness is good, but floods and droughts is dual-purpose; Also can be used in the high soil of chisley soil and sand grain content, can effectively prevent open-air installation process, root system of plant and soil toy destruction device.

Embodiment:
Referring to Fig. 1 and Fig. 2, the present invention is a kind of soil profile gas original-position collecting device, and it comprises outer protection tube 1 and interior sampling pipe 2; Should protect tube wall and the full air hole 11,21 of interior sampling pipe wall cloth outward, and see Fig. 3 and Fig. 4, (can seal stickup through water-proof silica-gel) pasted in sealing of sampling pipe 2 outer walls in this has waterproof ventilated membrane 3; This waterproof ventilated membrane 3 is processed by the high-molecular polythene material; Outside this waterproof ventilated membrane 3 gauze 4 is set, in the present embodiment, this gauze 4 is 300 purpose nylon gauzes.One end of this device adopts 5 sealings of first silica gel plug; In the middle of adopting, the other end is equipped with second silica gel plug, 7 sealings of gas conduit 6; One end of this gas conduit 6 stretches into interior sampling pipe 2 middle parts; The other end extends upward after stretching out outside the outer protection tube 1, and its port 61 adopts 8 sealings of the 3rd silica gel plug, and this gas conduit 6 is processed by the PVC flexible pipe.
During use; With the pre-buried certain depth of device to soil profile; After a period of stabilisation, sampling pipe 2 inside in the gas in the soil aperture gets into through diffusion, the aqueous water in the soil then is blocked in outside the pipe by the waterproof ventilated membrane 3 that the high-molecular polythene material is processed.Adopt the syringe of band syringe needle to pierce through the 3rd silica gel plug 8 that extends to the outer gas conduit 6 of outer protection tube; Through slowly bleed, exhaust; Gas in the interior sampling pipe 2 is fully mixed; Slowly extract 10ml gas appearance, the gas of adopting is transferred in Dewar bottle or the airbag and is stored, and also directly sealing injection device syringe needle stores.
