Abstract
The invention discloses an improved draining plate. Transverse lateral supporting plates and longitudinal supporting plates are additionally arranged on the basis of the structural form of a plate core of a traditional draining plate, so that the rigidity of the plate core of the draining plate is improved, the deformation resisting capability of the draining plate is improved, and thus the influence of deformation of the draining plate on the draining amount is weakened. The plate core and a filter membrane are bonded through the transverse lateral supporting plates and prevented from sliding and deforming, so that the draining plate is not likely to be blocked, and strengthening efficiency is higher. The draining plate is made of degradable materials, so that the problems that settlement continues, the subsurface structure is damaged, and soil is contaminated are solved. Besides, the improved draining plate is simple in technology, and factory operation improvement is facilitated.
Description
Technical field
The invention belongs to treatment of soft foundation band drain technical field, relate in particular to one and can promote draining, improve consolidation effect, and the modified band drain of degradable environmentally-friendly.
Background technology
At present, more often use band drain to carry out draining in treatment of soft foundation, see attached Fig. 1 and 2, traditional band drain is made up of plate core (1) and filter membrane (2).Wherein plate core (1) with multiple by the center brace panel (1-1) of a horizontally set are vertically fixed in center brace panel (1-1) and the groove tooth (1-2) of spaced set and form, teeth groove (4) (gap between teeth groove and adjacent castellations) is as the passage of foundation soil body drainage exhaust, filter membrane (2) is coated on plate core (1) outside, and the effect playing anti-filter prevents from the soil body particle from entering plate core blocking.But find in Practical Project: band drain can occur bending and deformation along with the sedimentation of ground, the phenomenon such as be even distorted, fold, and greatly can weaken the drainage effect of band drain; Conventional discharge plate only has the tip of plate core teeth groove and filter membrane to contact with each other, and less contact area makes the two be difficult to paste, and the two is slippage mutually easily, easily makes soil body particle enter plate in-core and alluvial blocking occurs; After basement process completes, band drain in ground is still the passage that the soil body continues consolidation draining, can cause continuation sedimentation, and the band drain left over meeting contaminated foundation soil property, there is impact to underground structure in future (stake, ground-connecting-wall etc.), jeopardize upper building safety.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide one can promote draining, improve consolidation effect, and the modified band drain of degradable environmentally-friendly.
The present invention is achieved by the following technical solutions:
A kind of modified band drain, comprises plate core and filter membrane, and it is outer that filter membrane is coated on plate core, and described plate core comprises center brace panel, groove tooth, cross side gripper shoe and longitudinal supporting plate; Wherein, center brace panel is arranged on the centre position of whole plate core, and groove tooth equally spacedly vertical interlaced is fixed in center brace panel; Described cross side gripper shoe is symmetricly set on the both sides of center brace panel, and cross side gripper shoe is fixedly connected with the two ends of groove tooth; The both sides of described longitudinal supporting plate are connected with cross side gripper shoe.
In technique scheme, described cross side gripper shoe is inclined flat pattern entity structure, and the wide of cross side gripper shoe is 1-3cm.
In technique scheme, cross side gripper shoe is along longitudinal spaced set of band drain.
In technique scheme, described longitudinal supporting plate is entity structure, its height and the distance that band drain is contour, length equals distance between adjacent groove tooth, width equals between two cross side gripper shoes.
In technique scheme, longitudinal supporting plate is positioned on the wide trisection line of whole band drain plate.
In technique scheme, cross side gripper shoe is connected with filter membrane.
In technique scheme, described plate core adopts degradation plastic to make, and filter membrane adopts biodegradable fiber to make.
The using method of described modified band drain: band drain is longitudinally vertically set in (or nuzzling in advance) soft foundation, the top of band drain is connected with suction vaccum drainage means, make to produce negative pressure in band drain by inhaling vaccum drainage means, thus impel the moisture in soft foundation to enter into teeth groove through filter membrane, and upwards discharge moisture content along teeth groove.
Advantage of the present invention and beneficial effect are:
The first, by increasing cross side gripper shoe and longitudinal supporting plate on the form of structure basis of conventional discharge plate plate core, improve the rigidity of band drain plate core, improving its non-deformability, therefore weaken band drain and be out of shape the impact that displacement is brought.The second, both plate core and filter membrane are mutually bondd by cross side gripper shoe, prevent sliding deformation therebetween, thus band drain is not easily blocked, reinforcing efficiency is higher.3rd, the material of band drain is changed to degradable material, solves the problem continuing sedimentation, harm underground structure and pollute soil property.In addition, the technology of the present invention is simple, is convenient to factory's operations improvement.
