Description

A kind of novel drainage plate

Technical field

The utility model relates to building, afforestation project field, is specially a kind of novel drainage plate.

Background technology

At present, the band drain made from plastic material is widely used in building field, as: the draining under roof and the ground, the waterproof of the interior wall face of underground construction, engineerings such as draining are protected in golf course, roof, the greening of road both sides.But existing band drain structural strength and supporting capacity are all poor, when being rolled by weight or stressedly being very easy to be extruded damage when excessive, have a strong impact on the performance of drainage.The most function ratio of existing in addition drainage plate is more single, can only draining there be water storage function, aspect the water conservation of preserving moisture, especially in engineerings such as place plantation, roof greening, because the thin ability of self regulating of soil layer is low, plant of being planted and flowers are also easily withered dead.The product of energy drainage is also arranged in the market, but all be to be spliced by fritter, the manufacturing cost height, construction is complicated, easily causes seepage.

Therefore, in order further to improve the supporting capacity and the structural strength of present drainage plate, accomplish can water conservation again can draining, construction is simple.It is a kind of rational in infrastructure that the utility model provides, and mechanical property is good, is convenient to be shaped, and makes simply multi-functional drainage plate.

Summary of the invention

The scheme that the utility model adopted is: a kind of novel drainage plate, the two-sided concave-convex pyramid plate body of making for plastics.The pyramid plate body can utilize methods such as mold pressing, plastic uptake and roll extrusion, on entire plate/sheet material, be processed into the staggered pyramid stage body that highly equates of a series of two-sided concave-convexes, there is v-depression to connect mutually between the adjacent frustum of a pyramid body unit, and pyramid stage body top is a facet, and its structure can be made into triangular pyramid, rectangular pyramid and polygonal pyramid stage body.

Lay is easy to seep water on the drainage plate during construction Composite Permeability filtration beds such as geotextiles.

Because it is that the polygonal pyramid stage body constitutes that pyramid plate body described in the utility model adopts the two-sided concave-convex pyramidal shape, and is that integral body processes, and interacts on the structure, supports mutually, has constituted a firm integral body.Have very big advantage at aspects such as energy absorption and dissipation, have good resistance to compression mechanical property.Because a series of concavo-convex pyramid stage bodies staggered, that highly equate are arranged on the pyramid plate body, there is v-depression to connect mutually between the adjacent frustum of a pyramid body unit, but water supply and draining and ventilative, therefore sunk pyramid stage body (V-shaped groove is with the lower part) has just constituted the retaining groove, and unnecessary like this water can be discharged from the v-depression between the frustum of a pyramid body unit.Simultaneously, can collect water unnecessary in the soil in the sunk pyramid stage body and be stored, realize the regulating pondage aqueous vapor, the function of the water conservation of preserving moisture.From manufacturing the stereochemical structure that the polygonal pyramid stage body is made up of several planes, owing to be shaped as polygonal pyramid platform shape, forming technology is simple easily, be difficult for tearing when being shaped, and materials are economized, cost is low, product defects is few, the easily demoulding in preparation process, but continuous high-efficient production.Lay filtering layer geotextiles during construction is passed through to stop the earth particulate, thereby is avoided passage to block, and makes the duct draining unimpeded.

The remarkable excellent results of a kind of novel drainage plate described in the utility model is:

1) mechanical property excellence, but load-bearing be not afraid of and jam on, be a kind of resistance to compression, high-strength light and multifunctional novel drainage plate of new construction;

2) energy drainage regulating pondage aqueous vapor, the water conservation of preserving moisture is a kind of novel drainage plate that is widely used in fields such as construction work and afforestation of city;

3) manufacture craft is simple, be convenient to be shaped, and be a kind of low cost new drainage plate of suitable large-scale mass production.

The specific embodiment

Shown in Fig. 1,2,3,4, pyramid plate body described in the utility model is to form through processes such as mold pressing, plastic uptake and roll extrusion with monoblock plastic plate or sheet material, upper and lower surface is a series of concavo-convex staggered pyramid stage bodies that highly equate, concavo-convex adjacent inclined-plane 2 is shared, thereby form the interdependent each other two-sided concave-convex frustum of a pyramid shape structural entity that interacts, the frustum slant edge junction of projection can form v-depression 3, and the pyramid unit on the monoblock pyramid plate body is connected mutually.The taper stage body of projection can be triangular pyramid, rectangular pyramid and polygonal pyramid shape stage body.

Mechanical property, drainage performance that the physical dimension of the unit pyramid stage body on the pyramid plate body and the material of selected sheet material or sheet material, thickness directly influence prepared pyramid plate body and the complexity that shapes, to take all factors into consideration when therefore preparing, carry out design alternative.

For mechanical properties such as the resistance to compression that improves novel drainage plate, bending resistances, pyramid plate body both sides also can be bonded with impregnation grid cloth or metal, nonmetal sieve plate, to strengthen the performance of drainage plate, adapt to the needs (as shown in Figure 5) of some special occasions.

Described permeatable filter layer is certain thickness composite material, is 100～250g/ square metre nonwoven as geotextiles or specification, covers on the drainage plate, passes through in order to stop the earth particulate, thereby avoids passage to block, and makes the duct draining unimpeded.

Below in conjunction with specific embodiment the utility model is described further.

Example 1, as shown in Figure 1 and Figure 2, a kind of novel drainage plate described in the utility model is the polypropylene plastics sheet material that the pyramid plate body can adopt 0.5mm, be rolled into width certain-length pyramid plate body coiled material arbitrarily through heating and forming rolls press, direct lay during site operation is that 100～250g/ square metre nonwoven is laid on the pyramid core version at last with specification.

Example 2, as shown in Figure 5, rolled epoxy resin adhesive with evenly being coated with on the little frustum of a pyramid of the obtained pyramid plate body plane 1, and the impregnation grid cloth 5 of the pre-soaked resin matrix of 1mm sticked together with the pyramid plate body, put into the enhancement mode drainage plate of hot press heating, pressurization or normal temperature cure system, under its effect, play invigoration effect, improved the mechanical properties such as resistance to compression bending resistance of drainage plate.The nonwoven that during site operation with specification is 100～250g/ square metre again is laid on the drainage plate.

When example 3, the construction of drainage plate lay, the seam of two or two pyramid plate bodys adopts the form of overlap joint.If when being bonded with the impregnation grid cloth on pyramid plate body two surfaces, impregnation grid cloth relativity shift certain size, the little frustum of a pyramid of part is respectively reserved on two sides on the pyramid plate body, shown in Fig. 6 a, Fig. 6 b, the mutual overlap joint of seam when for laying the drainage plate being installed, anti-sealing is from drainage plate seam crossing seepage.

Example 4, the pyramid stage body above the pyramid plate body described in the utility model also can be made and be processed into the truncated cone shape, and embodiment is the same.
