4th, breather valve 5, tracheae snap ring 6, connector 7, loose collar 8, hollow bushing 9, permeable madreporic canal 10, fixing clasp 11, circular cone probe
12。
As shown in figure 1, the quick water fetching device being pressed into the present embodiment by static cone penetration equipment include upper sleeve 4,
Hollow bushing 9, permeable madreporic canal 10 and circular cone probe 12, wherein circular cone probe 12 are fixedly mounted on the bottom of hollow bushing 9, are easy to
The soil body is pressed into by static cone penetration equipment, the inside of hollow bushing 9, upper sleeve are built in as the permeable madreporic canal 10 of screen pipe
4 are connected with the top of permeable madreporic canal 10.
As shown in figure 1, permeable madreporic canal 10 bottom end seal and be installed with fixing clasp 11, in hollow bushing 9
Top is installed with loose collar 8, and the external diameter of fixing clasp 11 is less than the internal diameter of loose collar 8.As shown in Fig. 2 in upper sleeve 4
Lifting under, permeable madreporic canal 10 stretches out in hollow bushing 9.As permeable test tube 6 gradually stretches out hollow bushing 9, stroke is being stretched out
Extreme position, fixing clasp 11 is close to loose collar 8, and now permeable madreporic canal 10 can not continue to stretch out, and it stretches out stroke quilt
Cooperation institute between fixing clasp 11 and loose collar 8 is spacing, it is to avoid permeable madreporic canal 10 is drawn out from hollow bushing 9.
As shown in figure 1, be installed with connector 7 on the top of permeable madreporic canal 10, permeable madreporic canal 10 by connector 7 with
Upper sleeve 4 is connected to a fixed.Be provided with breather valve 5 at the middle part of connector 7, breather valve 5 with the body of permeable madreporic canal 10
Portion constitutes connection.When permeable madreporic canal 10 is overall is completely disposed at the inside of hollow bushing 9, connector 7 and the close phase of loose collar 8
Patch, it is to avoid in process of press in, underground water is entered among permeable madreporic canal 10.
