The breach of shape, by by sophisticated alignment notch insert body when, plug-in unit radially outward pushes away drainage element, so that drainage element prolongs
Stretch out body.
The utility model is further arranged to：The plug-in unit is hollow tubular structure, and the external diameter of plug-in unit is less than the interior of body
Footpath, the surface distributed of plug-in unit have inlet opening.
By using above-mentioned technical proposal, plug-in unit can also be used as drainage channel in itself, reduce to body internal drainage space
Occupancy；The external diameter of plug-in unit is less than body internal diameter so that plug-in unit will not extrude drainage element completely body, and drainage element one end is located at
In body, the other end is external positioned at this, convenient to introduce this external water in body.
The utility model is further arranged to：The bottom of the body is provided with the locating slot for being used for being embedded for tip.
By using above-mentioned technical proposal so that fixed when plug-in unit is fixed in body more solid and reliable.
The utility model is further arranged to：Chisel is provided with gutter, the diaphragm seal extension around the soft soil foundation
To gutter and stick the bottom wall and madial wall in gutter.
By using above-mentioned technical proposal, the water that gutter can be used for guiding vacuum suction apparatus to extract out is with discharging weak soil
Base；Simultaneously diaphragm seal extend in the gutter in and it is interior be lining in gutter, can not only prevent oozing under water in gutter, while can
To be fixed using water to diaphragm seal.
The utility model is further arranged to：Geotextiles are equipped between the diaphragm seal and sand bedding course.
By using above-mentioned technical proposal, can avoid scraping breakage between diaphragm seal and sand bedding course.
In summary, the utility model few, single displacement hull radiation scope that provides a kind of unit volume displacement hull dosage
Wide soft soil foundation discharge structure.
