The utility model has the advantages that this soft foundation discharge fixing is in strong drain bar, draining plate body is inserted into soft soil foundation, in hydraulic pressure
Under the effect of power difference, pore water seepage flow enters in the vertical drainage channel constituted between core plate and filter membrane, when water level in drain bar body
It is higher to form Venturi effect in jet pipe body so that water pressure subtractive hour, is passed through high-pressure fluid by conduit, it will be vertical
Pore water in drainage channel is sucked out and passes through the conduit of other side and discharges, so that vertical drainage in-channel water position
Reduce, again draining plate body and around that water pressure is formed between weak soil is poor so that seepage flow enters pore water from weak soil again
In drain bar body, so repeats, achieve the effect that soft soil foundation quick-discharging consolidation from top to bottom.
Detailed description of the invention
The present invention is described further with reference to the accompanying drawings and examples；
Fig. 1 is the cross section structure schematic diagram of first embodiment of the invention；
Fig. 2 is the cross section structure schematic diagram of second embodiment of the invention；
Fig. 3 is the structural schematic diagram that draining plate body and jet stream tube body are used cooperatively in the embodiment of the present invention.
Specific embodiment
Referring to Figures 1 and 2, the strong drain bar of soft foundation discharge fixing of the present invention, including draining plate body, drain plate body packet
The filter membrane 30 for including core plate 10 and being coated on outside core plate 10, wherein core plate 10 is connected in length and breadth by lateral plate body 11 and longitudinal plate body 12
It constitutes, forms cross-shaped structure, it is logical that the gap between core plate 10 and filter membrane 30 constitutes the vertical drainage entered for pore water seepage flow
Road 14, when draining plate body insertion soft soil foundation in, water pressure difference effect under, pore water can seepage flow enter core plate 10 and filter membrane
In the vertical drainage channel 14 constituted between 30.10 left and right sides of core plate is vertically respectively equipped with the conduit 13 for fluid flowing,
The setting fixed form of conduit 13 have it is a variety of, can be fixed for detachable connection, at this point, conduit 13 can it is separately fabricated plus
Work, molding conduit 13 directly snap onto the gap between adjacent longitudinal plate body 12；Or be integrally formed and fix, it leads
By being integrally formed, the position of conduit 13 can be preferably vertical in the left and right sides according to practical adjustment for pipe 13 and core plate 10
To on the end face of plate body 12.
Preferably, the filter membrane 30 being coated on outside core plate 10 is set as Nian Jie with longitudinal plate body 12, and specifically, adjacent longitudinal direction
The marginal end portion of plate body 12 constitutes tooth-shape structure, and filter membrane 30 is bonded on the tooth tip of tooth-shape structure, thus, vertical drainage channel 14
It is divided into multiple adjacent but mutually independent unit area, in this way, during draining plate body insertion soft soil foundation, even if portion
Filter membrane 30 is divided to be scratched, the entire function of draining plate body is also unaffected, the unit area where other undamaged filter membranes
Interior vertical drainage channel 14 still can work on.
Wherein, lead line can also be preset in the conduit 13 of 10 two sides of core plate, lead line under the effect of external force may be used
To pull out, the surface of lead line has scale numerical value, after draining plate body squeezes into soft soil foundation, it is only necessary to ground to pull out
Lead line can read the length of insertion portion draining plate body from the scale on lead line, and easy to operate, measurement is accurate.
Draining plate body of the invention is used cooperatively with jet stream tube body 20, realizes the quick-discharging consolidation of soft soil foundation.
Referring to Fig. 3, jet stream tube body 20 is respectively provided with fluid inlet 21, fluid outlet 22 and water sucting port 23, jet stream tube body
20 inner hollows form the jet stream inner cavity that front and back is connected with fluid inlet 21, fluid outlet 22 respectively, it is preferable that fluid inlet 21
It is in front of and after same axial orientation and arranges with fluid outlet 22, jet stream inner cavity is in turn divided into circular cone contraction section 24 along axial direction, puts down
Straight section 25 and circular cone diffuser 26, circular cone contraction section 24 connect with fluid inlet 21, fluid by fluid inlet 21 entrance after, according to
It is secondary by circular cone contraction section 24, flat segments 25 and circular cone diffuser 26, most discharged afterwards through fluid outlet 22.Water sucting port 23
Positioned at the side wall of jet stream tube body 20, being located on the outside of circular cone contraction section 24 in jet stream tube body 20 has annular cavity 27, in annular
Chamber 27 is connected with water sucting port 23, and the intersection of circular cone contraction section 24 and flat segments 25 forms ring port, so that penetrating
Stream inner cavity is connected with annular cavity, i.e., water sucting port 23 is also connected to jet stream inner cavity.
Wherein, the fluid inlet 21 of jet stream tube body 20 is connected with the conduit 13 of wherein side, fluid outlet 22 in addition
The conduit 13 of side is connected, and water sucting port 23 is connected with vertical drainage channel 14, by draining plate body and 20 groups of jet stream tube body
Connection is closed, is squeezed into soft soil foundation by plate construction, the pore water under the effect of underground water head pressure difference, in soft soil foundation
Can seepage flow enter in vertical drainage channel 14, when water level is higher so that when water pressure subtractive is small in vertical drainage channel 14, pass through
Conduit 13 is passed through high-pressure water body through fluid inlet 21, and high-pressure water body is flowed by jet stream inner cavity, when by circular cone contraction section 24, produces
Raw Venturi effect, flow velocity are speeded so that low pressure is generated at annular cavity 27, to constantly will vertically arrange by water sucting port 23
It is intracavitary in the pore water inspiration jet stream gathered in aquaporin 14, as high-pressure water body is discharged through fluid outlet 22 together, such as
This reduces water level in vertical drainage channel 14, and formation water pressure is poor between recovery draining plate body and surrounding weak soil again, makes
Pore water enter in vertical drainage channel 14 from seepage flow in weak soil again, so repeat, thus reach soft soil foundation by up to
The effect of lower quick-discharging consolidation.
Embodiments of the present invention are explained in detail above in conjunction with attached drawing, but the present invention is not limited to above-mentioned embodiment party
Formula within the scope of knowledge possessed by those of ordinary skill in the art can also be before not departing from present inventive concept
Put that various changes can be made.
