Description
Technical field
The present invention relates to soft foundation processing technology field more particularly to a kind for the treatment of of soft foundation drainpipes and mating drain bar.
Background technique
In soft base vacuum preloading process, needs to take the water in soft base away using vacuum pump, generally pass through draining
It manages with drain bar and realizes, drainpipe need to be embedded in the medium coarse sand bed course of 50cm thickness, and plastic draining board one end is inserted into soft base,
Other end need to manually be bound on drainpipe, and vacuum pump is directly connected to drainpipe, vacuum transmission path be successively drainpipe,
Sand bedding course, plastic draining board, Soft Soil Layer, each transmission link can have the loss of vacuum transmitting, to influence treatment of soft foundation
Effect.The generally circular in cross section section pvc pipe of current drainpipe, there is a non-woven geotextile filter membrane outside, pipe shaft use bellows fashion with
Ground inhomogeneous deformation is adapted to, has the pumping draining small hole penetrated that should meet the pumping draining between sand bedding course, sand in tube wall
Bed course is generally the medium coarse sand of 50cm or so thickness, and in Large-area Vacuum Preloading processing engineering, sand dosage is big, greatly increases engineering
Cost.
Summary of the invention
To overcome drainpipe used by existing treatment of soft foundation and drain bar to need to fill a large amount of medium coarse sands, vacuum is caused to pass
Pass loss big, low efficiency, labor intensity and it is at high cost the deficiencies of, the technical problems to be solved by the present invention are: providing a kind of true
The treatment of soft foundation drainpipe and mating drain bar that sky loss is small, at low cost, installation and drainage efficiency are high.
The technical solution adopted by the present invention to solve the technical problems is:
Treatment of soft foundation drainpipe and mating drain bar, the drainpipe include interconnected water delivery section and linkage section, institute
The bottom for stating linkage section is equipped with bayonet, the upper end of the drain bar can clamping be sealed at the bayonet of linkage section.
Further, the both ends of the bayonet length direction are respectively equipped with a support bar, the upper and lower ends of support bar
Be connected respectively with linkage section top and bottom, the inside of the support bar is equipped with the first fixed tooth, the two sides of the drain bar be equipped with
The second fixed tooth that first fixed tooth matches.
Further, the material of the support bar is rigid plastics.
Further, being equipped with sealing block on the outside of the bayonet of the linkage section, a circle is equipped with along bayonet on the sealing block
Towards the groove below linkage section, seal weatherstrip is equipped in the groove.
Further, the water delivery section of the drainpipe and the radial section of linkage section are semicircle.
Further, the water delivery section of the drainpipe is bellows.
The beneficial effects of the present invention are: installation effectiveness is high, and stable connection can using the direct clamping of drain bar and drainpipe
It leans on, vacuum transmission path can be made directly to reach drain bar from drainpipe, greatly reduce the true of sand bedding course link in traditional handicraft
Sky loss, semi-circular cross-section drainpipe need the medium coarse sand of making less, both reduce engineering compared with typical circular section drainpipe
Cost, and improve construction efficiency.

Specific embodiment
The following further describes the present invention with reference to the drawings.
As shown in figs. 1 to 6, treatment of soft foundation drainpipe and mating drain bar of the invention, the drainpipe include mutually interconnecting
Logical water delivery section 1 and linkage section 2, the bottom of the linkage section 2 are equipped with bayonet 21, and the upper end of the drain bar 3 can clamping sealing
At the bayonet 21 of linkage section 2.The clamping sealing means can be used plastics interference fit and realize.
Use process of the invention is: drain bar 3 being inserted into soft base first, then arranges drainpipe, and will draining
The upper end water outlet of plate 3 is inserted at the bottom bayonet 21 of linkage section 2, is re-layed a small amount of medium coarse sand, is finally started vacuum pump,
The water in soft base is taken away by drainpipe and drain bar 3.
In order to improve the reliability that drain bar 3 is connect with linkage section 2, set respectively at the both ends of 21 length direction of bayonet
There is a support bar 4, as shown in figure 3, the upper and lower ends of support bar 4 are connected with 2 top and bottom of linkage section respectively, the support bar 4
Inside be equipped with the first fixed tooth 41, as shown in figure 4, the two sides of the drain bar 3 are equipped with and match with the first fixed tooth 41
Second fixed tooth 31, as shown in Figure 5.Wherein the preferably upper lateral tooth flank of the first fixed tooth 41 is horizontal, the inclined form of the downside flank of tooth,
And the second fixed tooth 31 is then exactly the opposite, upper lateral tooth flank inclination, the downside flank of tooth is horizontal, which can be convenient for the insertion card of drain bar 3
Mouth 21, and can prevent drain bar 3 from falling off.
The material of the support bar 4 is rigid plastics.Using rigid plastics, on the one hand can be deformed using plastotype being inserted into and
Dismantle drain bar 3, on the other hand can play certain supporting role to linkage section 2, avoid linkage section 2 deform and influence drainpipe with
The connection situation of drain bar 3.
In order to improve the efficiency of draining, other than the reliability that drainpipe to be guaranteed is connect with drain bar 3, it is also necessary to as far as possible
Consume of the vacuum in transmittance process is reduced, that is, improves the leakproofness of connection, therefore, further embodiment is in the linkage section
It is equipped with sealing block 5 on the outside of 2 bayonet 21, encloses as shown in fig. 7, being equipped with one along bayonet 21 on the sealing block 5 towards under linkage section 2
The groove 51 of side, the groove 51 is interior to be equipped with seal weatherstrip 52.Due to traditional plastic draining board, such as SPB-C plastic draining board
Solar absorber surface be equipped with slot tooth, outside is also cased with filter membrane 6, and being directly connected with the bayonet 21 of linkage section 2 will appear gap, influences very
Sky transmitting.After increasing sealing block 5, during plugging, the filter membrane 6 in outside can compress to be stacked into groove 51 plastic draining board
It is interior, and play the role of improving leakproofness under the action of seal weatherstrip 52, prevent silt from entering drainpipe from bayonet 21.
The generally circular in cross section pipe of traditional drainpipe, and the present invention for the ease of with 3 grafting of drain bar, by the drainpipe
It is semicircular structure type that water delivery section 1 and linkage section 2, which are designed to radial section,.Semicircular pipe also has some other
Advantage, for example, it is big with contact area of ground, it is not easy to roll and influence the connection with drain bar 3, and drainpipe height is lower, it can
Reduce the laying depth of plain soil.In addition, in order to adapt to the fluctuations of geology during treatment of soft foundation, by the drainpipe
Water delivery section 1 uses bellows.
The present invention transmits vacuum using the direct clamping of drain bar and drainpipe, reduces sand bedding course ring in traditional handicraft
The vacuum leak of section, semi-circular cross-section drainpipe need the medium coarse sand of making less, drop significantly compared with typical circular section drainpipe
Low engineering cost, improves construction efficiency, has good practicability and application prospect.
