Description
Technical field
The utility model belongs to engineering construction technology field, is related to soft base drain treatment apparatus, more particularly, to one
Kind integral plastic drainage board.
Background technique
In project of reclamation by pumping filling, the features such as bleeding, consolidation time after barged-in fill hydraulic reclamation are slow, intensity is low, engineering is given
Construction brings serious influence.In order to shorten consolidation time, rate of consolidation, the pre-plugged certain depth in soft base are promoted
Draining etc., to expand ground vertical drainage ability.The process of soft base discharging consolidation is the process that the super hydrostatic pressing of pore water dissipates,
The namely process of water exudation.The hole that water first passes through soil enters plastic draining board and then reaches sand bedding course, finally by rubble
French drain enters sump, using water pump will catchment well water be drawn through bright ditch be discharged it is over-the-counter.
Existing plastic draining board structure generally comprise the core plate with numerous longitudinal drainage slots and be wrapped in core plate or more and
The filter membrane of two side external surfaces, existing in following major defect: the junction of filter membrane and core plate is easy to loosen sliding, and work is unstable
It is fixed；Filter membrane under confining pressure easily collapses, and blocks longitudinal drainage slot；The spacing of draining tooth socket is smaller, and (mainly fearness filter membrane easily collapses not
Dare to increase spacing), impeded drainage.
Summary of the invention
The main purpose of the utility model is to provide a kind of filter membranes to consolidate in conjunction with the junction of core plate, the filter under confining pressure
The not givey integral plastic drainage board of film.
To achieve the above objectives, the present invention adopts the following technical solutions:
A kind of integral plastic drainage board including the core plate with numerous longitudinal drainage slots and is wrapped in core plate or more and two sides
The filter membrane of outer surface；It is characterized in that the filter membrane is through hot melt adhesion on core plate, the filter membrane is equipped at intervals with lateral loops
Shape stirrup.
Further,
The core plate is width 100mm, the rectangular slab of thickness 5mm, the spacing of transverse annular stirrup set by the filter membrane
For 10mm；The adjacent spacing of the longitudinal drainage slot of the core plate is 3mm, and the sidewall thickness of rhone is 1mm.
Compared with the prior art, the beneficial effects of the utility model are as follows:
Since the filter membrane is through hot melt adhesion on core plate, the filter membrane is equipped at intervals with transverse annular stirrup.In this way
Can make filter membrane and core plate is combined into firm monolithic construction, and junction is very secured, and the filter membrane under confining pressure is made to be not easy to collapse,
And the adjacent spacing of longitudinal drainage slot can be made to increase, guarantee drain bar functional reliability to reach, increases logical draining section
Area, hence it is evident that drainage efficiency is improved, explains cost, it is splendid through test effect.Test result: meet hydraulic reclamation depth pay, work
Phase it is short and require foundation bearing capacity high engineering specifications under, guarantee to meet the longitudinal flowing water measuring of drain bar not less than 75cm2/ s with
And filter membrane infiltration coefficient is not less than 4.5 × 10-3The requirement of cm/s.
Detailed description of the invention
Fig. 1 is the utility model embodiment structural schematic diagram (perspective view).
Fig. 2 is the front portion structure enlarged diagram of Fig. 1.
Fig. 3 is the overlooking structure diagram of Fig. 1.
Specific embodiment
Referring to Fig. 1~3, a kind of integral plastic drainage board including the core plate 3 with numerous longitudinal drainage slots and is wrapped in core
Plate up and down and two side external surfaces filter membrane 2；It is characterized in that the filter membrane 2 is the filter through hot melt adhesion on core plate 3
Film 2 is equipped at intervals with transverse annular stirrup 1.
The core plate 3 is width 100mm, the rectangular slab of thickness 5mm, between transverse annular stirrup 1 set by the filter membrane 2
Away from for 10mm；The adjacent spacing of the longitudinal drainage slot of the core plate 3 is 3mm, and the sidewall thickness of rhone is 1mm.
The detection data that plastic draining board described in the present embodiment is given below is as follows:
The detection data table of 1 the utility model plastic draining board of table
The index of the provable the present embodiment of testing result has made marked progress.
Plastic draining board described in the utility model is given below installs and uses mode:
The utility model drain bar is inserted into soft layer with board-plugging device, forms vertical drainage system, and in plastic row
At the top of water plate then setting sand bedding course loads, native pore water is along plastic draining board as horizontal drainage channel in foundation surface
The groove of plate, which rises, overflows ground, to accelerate the infall process of soft foundation, ground is made to obtain densification reinforcing.
(1) drain bar is installed
According to the depth requirements of design plate, intubation length is set, and carries out and should insert drain bar depth mark.Drain bar
It interrupts inside sleeve pipe, is fixed on the bolt of sleeve bottom, while tensing drain bar, by drain bar and bolt from casing
Between frictional force link together, bolt is extracted out from sleeve opening and drain bar end when above mentioning, and casing proposes, drain bar is by soil
Pressure stays in ground.
(2) immersed tube plate
Drain bar is packed into reel, and drain bar is introduced into inserted link by the pulley on door frame.Casing is checked before plate
Verticality guarantees plate verticality within 1.5%.Drain bar is drawn from insertion rod end, is turned back, bar dowel (stake on folder
It is inserted on stake position when the setting-out of position), it is ordered with trigger is ordered.Drain bar is tensed, by insertion rod align piles position.Vibration is opened by insertion rod
It is pressed into ground.Make upper obvious mark according to the red paint of projected depth on casing, reaches projected depth (in advance in insertion rod with red
Paint draws upper mark) after insertion rod is extracted.Then drain bar is anchored in bottom hole by bar dowel.
(3) plastic draining board and head processing are cut
When promoting casing, when sleeve bottom leaves sand face 50cm, drain bar manually is cut off from sleeve bottom, in Base with Sand Gravel Cushion
Drain bar is cut in embedment gravel at the above 25cm.Then it will be left behind draining wrench bending and inject nozzle.The plastic row being plugged
People's sand bedding course is buried on water plate, top, and embedment length is greater than 0.5m or meets design requirement.
