Abstract
The utility model relates to a device for discharging and dredging water for buildings, structures, landscape engineering, etc., which belongs to the technical field of capital construction engineering. The utility model is in a plate-shaped structure which is composed of a bottom plate, a tapered convex table of the bottom plate, and filter layer non-woven cloth, wherein water can pass through the filter layer cloth which prevents the pass of mud particles, and permeated water flows through a gap of the convex table to be discharged. The plate for discharging and dredging water can be used in places where excess water in mud needs to be discharged, for example the utility model can discharge and dredge water above or under a foundation of a building, water behind the side wall of a retaining wall and an underground foundation, water under a football court and a lawn, water in a subway and a tunnel, etc. By using the device, the water discharging and dredging effect is obviously improved. The utility model has the advantages of convenient construction, short construction period and low engineering cost.
Description
The utility model belongs to the capital works technical field, is a kind of hydrophobic devices of draining such as building and structures and afforestation project that are used for.
As everyone knows, a kind of good effective draining draining system is to the construction period of capital works or afforestation project, and all there is material impact in the normal use and the life-span thereof of building and structures.For example, above the basis of building or below, below the road foundation, retaining wall is subjected to piezometric surface etc. that drainage blanket is set, and helps improving its application life.Traditional white-out water mode is to make of brick stone etc. to lead filtering layer, and more is with cobble or rubble, ballast aggregate, brickbat etc. as the drainage layer, unnecessary moisture content white-out to the appointed place.This white-out water mode effect is not satisfactory.And the time is long slightly, and silt stops up the white-out water layer easily.
The purpose of this utility model be to provide a kind of be used for building etc. and structure and greening substrate, road bases be difficult for by silt stop up, the effective draining steam trap connection of white-out water.
The draining steam trap connection that is used for building and structures etc. of the utility model design is made up of plastic cement base plate and filtering layer nonwoven (geotextiles).Wherein, base plate is provided with the tapered bosses of the equal altitudes of Discrete Distribution, and the filtering layer nonwoven is bonding to be covered on the end face of tapered bosses.Can glued joint between filtering layer cloth and the tapered bosses.As shown in Figure 1.The drainage board that forms a whole like this.The effect of filtering layer nonwoven is to allow the water can infiltrate, and prevents that the earth particulate from seeing through, thereby avoids aquaporin to stop up.Convex on the base plate can support the pressure that the drainage board both sides are subjected to, and the space between the convex is used for unimpeded draining.
The drainage board of the utility model design, convex wherein can be the taper shape, also can the side's of being cone-shaped, also can be other shapes, comparatively suitable is the taper shape.
In the above-mentioned drainage board, the thickness of base plate is generally 0.6-1.5mm.The bottom maximum gauge of tapered bosses is 10mm-50mm, and top diameter is the 5/10-7/10 of base diameter.The height of convex is 10mm-50mm.Less its of diameter is highly lower, and bigger its of diameter is highly also higher.Convex is Discrete Distribution on base plate.Usually, diameter is less, and is highly lower, and the distribution density of convex is bigger; Diameter is bigger, and is highly higher, and convex density is less.Usually, the centre distance of convex is 15-90mm.
Above-mentioned drainage board also can be designed to the form of two-sided convex, promptly all is evenly distributed with tapered bosses in the two sides of a base plate, and one deck filtering layer nonwoven is gluedd joint at the top of both sides convex equally, as shown in Figure 2.The drainage board of this two-sided convex needing can be used for the occasion of both sides white-out water.Also can only glued joint one deck filtering layer nonwoven at a pleurapophysis platform top.This drainage board can be used for occasions such as afforestation, roadbed.
The plastic material of the available anti-HI high impact of the base plate of above-mentioned drainage board (comprising convex), anti-high pressure for example, uses polystyrene material, punch forming.At present, a monoblock drainage board area can be 1120 * 600mm.During use, its splicing can be laid.
Base plate and convex in the above-mentioned drainage board are generally thin wall construction.In order to increase the compressive strength of convex, waling can be set in the convex side.The quantity of each convex reinforcing rib is generally the 2-5 bar, is distributed in the side of convex, as shown in Figure 3.
The drainage board of the utility model design, it mainly acts on is hydrophobic, draining, this drainage board all can be used in all places that needs to discharge excessive moisture in earth, adopts cobble or ballast aggregate to come place hydrophobic, draining to need to use this drainage board especially especially originally.For example: the following white-out water on top (underground garage) of (1) building foundation or basis, (2) retaining wall and underground foundation side wall white-out water behind; (3) roof garden, the white-out water under football field and the greening lawn; (4) the white-out water in subway, tunnel; (5) the white-out water of road foundation, dykes and dams, high mountain bank protection, or the like.
Compare as the situation of drainage layer with adopting cobble, adopt this drainage board to have following superiority: white-out water effect is obviously improved, and has avoided the obstruction of silt particulate to the flowing water space; Weight greatly alleviates, and installation is convenient, can shorten construction period, reduces construction costs.
Embodiment: adopt the high impact polystyrene plastic plate, thickness 10mm, the design one side has garden conuli platform, evenly distributes, convex base diameter 10mm, top diameter 6mm, height 12mm, the convex center distance is 18mm.One time punching molded.Area 1120 * 600 (mm), its compressive strength reaches 600KPa.Filtering layer adopts the polypropylene fibre terylene non-woven fabric, and the top of glueing joint convex on base plate promptly gets required drainage board.
Fig. 1 is drainage board structure (section) figure of single face convex.
Fig. 2 is drainage board structure (section) figure of two-sided convex.
Fig. 3 is provided with the diagram of reinforcing rib for convex.
Number in the figure: 1 is base plate, and 2 is the tapered bosses on the base plate, and 3 is the filtering layer nonwoven, and 4 is reinforcing rib.
