The bottom connection of mud pipe；Described hard spring housing is taking the outside of mud pipe, the described top of hard spring and the top of looped pipeline
Portion is connected, and the bottom of hard spring is with taking the outer wall of mud frustum cone side to be connected；
Described outer sleeve, looped pipeline and lower surface is in same level when taking mud frustum in the raw, it is described
Spring in its natural state in a state of nature；
The top of described outer sleeve is provided with external casing joint, for connecting external sleeve pipe；Described looped pipeline top
Portion is provided with external looped pipeline joint, and for connecting external looped pipeline, rotating handles is connected with the top of described external looped pipeline；Described
Take mud tube top portion to be provided with outside first to access mud pipe joint, mud pipe is accessed outside for connecting.
Pasted moreover, the lower surface of described hold-down support is provided with travel(l)ing rest, during described travel(l)ing rest nature
Hold-down support bottom surface is closed, perpendicular to the lower surface of hold-down support during working condition.
Moreover, the material of the hold-down support and travel(l)ing rest is stainless steel, described outer sleeve, looped pipeline, take mud pipe,
Hard spring, mud round platform, external looped pipeline are taken, mud Guan Jun is accessed outside and uses PC materials.
Moreover, according to requirements, the quantity of described external sleeve pipe is 0, the quantity of described external looped pipeline is 1
Individual, the described outer quantity for accessing mud pipe is 2.
Moreover, the outer surface of described external looped pipeline is provided with scale, the depth that looped pipeline penetrates bed mud can be determined.
Moreover, when described looped pipeline penetrates bed mud, hard spring is in compressive state.
The step of when the utility model uses, is as follows：
(1) travel(l)ing rest is opened, perpendicular to hold-down support, according to depth of water situation, external appropriate number of external sleeve pipe,
External looped pipeline and access mud pipe outside.After being completed, sampling assembled casing is vertically penetrated in water, after it is stable, will be revolved

Power is poor；Sampling initial stage, residue in and take air in mud pipe and river to be inhaled into extraction device；Upper lift handle, depresses plunger, this
When water check valve open, air and river are discharged；
(5) after repeating (4) for several times, the river bottom mud that is enclosed in looped pipeline will gradually be inhaled into and take mud pipe, access mud pipe outside
Until in extraction device；
(6) in sampling latter stage, due to the loss of bed mud, the bed mud height reduction in looped pipeline so that take mud round platform hard
Gradual snap looped pipeline lower surface, hard spring gradually tend to nature in the presence of matter spring, and the apparent phenomenon shows as extracting
Behavior becomes more easily, and it is river to draw up material almost all, now, takes mud process to terminate；
(7) after taking mud to terminate, pull down access mud pipe outside successively, sampling assembled casing is then proposed from bed mud, is torn open
Unload；To pull down it is outer access mud pipe, be sequentially connected extraction device, close water check valve, extrude the outer mud sample accessed in mud pipe and enter
Enter in sampling bottle, so far, take mud process all to terminate.
Exemplary description is done to the technical solution of the utility model above, it should explanation, do not departing from this skill
In the case of the core of art scheme, any simple deformation, modification or other skilled in the art can not spend creation
Property work equivalent substitution each fall within the protection domain of this patent.
