The requirement of shape water sample, lays the foundation to analyze the construction stratum before various engineering constructions；Can be in designated depth fast sampling, it is to avoid
Collection mixed sample, while avoid people from directly contacting water sample.
Brief description of the drawings
Fig. 1 is section of structure of the present utility model；
Section of structure when Fig. 2 is the utility model use state.
Embodiment
The utility model feature and other correlated characteristics are described in further detail by embodiment below in conjunction with accompanying drawing,
In order to the understanding of technical staff of the same trade：
As shown in Figure 1-2,1-8 is marked to be expressed as in figure：Upper sleeve 1, breather valve 2, connector 3, loose collar 4,
Drive pipe 5, permeable madreporic canal 6, fixing clasp 7, circular cone probe 8.
Embodiment：As shown in figure 1, the quick water fetching device being pressed into the present embodiment by static cone penetration equipment mainly includes
Upper sleeve 1, drive pipe 5, permeable madreporic canal 6 and circular cone probe 8, wherein circular cone probe 8 are fixedly mounted on the bottom of drive pipe 5
End, is easy to be pressed into the soil body by static cone penetration equipment, the inside of drive pipe 5 is built in as the permeable madreporic canal 6 of screen pipe, on
The top of parts casing pipe 1 and permeable madreporic canal 6 is connected.
As shown in figure 1, being installed with fixing clasp 7 in the bottom of permeable madreporic canal 6, fixed at the top of drive pipe 5
Loose collar 4 is installed, the external diameter of fixing clasp 7 is less than the internal diameter of loose collar 4.As shown in Fig. 2 under the lifting of upper sleeve 1,
Permeable madreporic canal 6 stretches out in drive pipe 5.As permeable test tube 6 gradually stretches out drive pipe 5, the extreme position of stroke is being stretched out
Place, fixing clasp 7 is close to loose collar 4, and now permeable madreporic canal 6 can not continue to stretch out, and it stretches out stroke by fixing clasp 7 with living
Cooperation institute between rotating ring 4 is spacing, it is to avoid permeable madreporic canal 6 is drawn out from drive pipe 5.
As shown in figure 1, be installed with connector 3 on the top of permeable madreporic canal 6, permeable madreporic canal 6 by connector 3 with it is upper
Parts casing pipe 1 is connected to a fixed.Be provided with the middle part of connector 3 can external connecting negative pressure device breather valve 2, breather valve 2 with it is permeable
The tubular body of madreporic canal 6 constitutes connection.When permeable madreporic canal 6 is overall is completely disposed at the inside of drive pipe 5, connector 3 is with living
