Port 23,20 inner hollow of jet stream tube body forms the jet stream inner cavity that front and back is connected with fluid inlet 21, fluid outlet 22 respectively, excellent
Selection of land, fluid inlet 21 and fluid outlet 22 are in arrangement before and after same axial orientation, and jet stream inner cavity is in turn divided into along axial direction
Circular cone contraction section 24, flat segments 25 and circular cone diffuser 26, circular cone contraction section 24 connect with fluid inlet 21, and fluid passes through fluid
After entrance 21 enters, circular cone contraction section 24, flat segments 25 and circular cone diffuser 26 are passed sequentially through, it is most outside through fluid outlet 22 afterwards
Discharge.Water sucting port 23 is located at the side wall of jet stream tube body 20, and being located on the outside of circular cone contraction section 24 in jet stream tube body 20 has ring
Shape inner cavity 27, annular cavity 27 are connected with water sucting port 23, and the intersection of circular cone contraction section 24 and flat segments 25 forms annular
Port, so that jet stream inner cavity is connected with annular cavity, i.e., water sucting port 23 is also connected to jet stream inner cavity.
In order to enable realizing smoothly connection, row between the vertical drain and water sucting port 23 that are formed in draining plate body 10
10 bottom of water plate body is socketed with the box body 30 that catchments, and catchment 30 bottom end opening of box body, and forms grafting port and insert with water sucting port 23
It connects.
Wherein, fluid inlet 21 and fluid outlet 22 are respectively connected with fluid conduit systems 28 respectively, and fluid conduit systems 28 stretch out soft
Soil base, the fluid conduit systems 28 connected by fluid inlet 21 can inject high pressure gas to the jet stream inner cavity of jet stream tube body 20
Or high-pressure water body.
Preferably, the fluid conduit systems 28 of left and right two are integrally formed in 10 left and right sides of draining plate body, i.e. draining plate body
10 left and right sides are respectively fixed with two fluid conduit systems 28, when draining plate body 10 is combined with draining plate body 10, the stream of left and right two
The port of body canal 28 forms with corresponding fluid inlet 21,22 grafting of fluid outlet be tightly connected respectively.
Preferably, the top opening of draining plate body 10 can be sealed processing, will be drained when by water sucting port 23
When the pore water discharge gathered in plate body 10, the water level drained in plate body 10 is reduced, due to being sealed at the top of draining plate body 10, so that
Certain vacuum degree can be generated inside draining plate body 10, and then the pore water seepage flow in soft soil foundation is further accelerated to enter draining
Inside plate body 10, drainage efficiency is improved.
It realizes that the method for soft soil foundation precipitating, pre-pressing is as follows by above-mentioned forced-ventilated water for prepressing device: plate body 10 will be drained and penetrated
The combination connection of flow tube body 20, is squeezed into soft soil foundation by plate construction, and the fluid conduit systems 28 of left and right two stretch out soft soil foundation,
Under the effect of underground water head pressure difference, the pore water in soft soil foundation can constantly flow into convergence through draining plate body 10, work as row
