Abstract
A pervious pipe for dewatering from soft foundation, soil, or earth structure is composed of the osmotic filer layer and the pipe with pervious holes or slits, and features that on said pipe there are convex strips for forming the drainage channels between adjacent convex strips. Its advantages are high water permeability and high dewatering efficiency.
Description
One), technical field
The present invention relates to a kind of water-permeable pipe of getting rid of infiltration.
Two), background technology
At present, in engineerings such as building, agricultural, often must carry out the draining of the soil body or structure inside, as dewatering, the row's of cutting underground water, soft basic draining or the like.In these drainage workss, relatively commonly used have a kind of draining central layer that has rhone, the outsourcing permeatable filter layer is formed band drain (as shown in Figure 1, Fig. 1-1 is the schematic cross-section of Fig. 1), the shortcoming of this band drain is: under extraneous soil pressure or other Construction traffics act on pressure effect on the soil, drainage channel between the rhone often is compressed, shown in Fig. 1-2, band drain is embedding dark more, extraneous load action is big more, compress greatly more, the drainage space of rhone is just more little, and its drainability is also just more little.
The water-permeable pipe that other is made up of a kind of ported sub outsourcing geotextile, as shown in Figure 2.Its drainage principle is: extraneous infiltration is infiltrated in the water-permeable pipe by the hole on the water-permeable pipe and is come draining, water-permeable pipe with holes is in order to guarantee the intensity of pipe itself, the general less than 10% of its percent opening, therefore, extraneous infiltration is extremely low by the efficient that permeable pore infiltrates in the water-permeable pipe, although bigger gutter cavity is arranged, do not bring into play its due effect.Be provided with more permeable hole or seam owing to water-permeable pipe with holes in addition, so its intensity reduction, vertically the bend resistance ability on descends greatly.
Three), summary of the invention
The object of the present invention is to provide a kind of overcome above band drain and water-permeable pipe shortcoming, make up the high water penetrating pipe with strip projected parts of permeability rate height, drainage efficiency of its advantage.
The object of the present invention is achieved like this: the water-permeable pipe that comprises permeatable filter layer and band permeable hole or seam, it is characterized in that described band permeable hole or seam water-permeable pipe are provided with and the strip projected parts of pipe ring to the direction that intersects, and form permeable rhone between the strip projected parts.
The cross sectional shape of described strip projected parts can be rectangle, arc, cast;
Can be provided with permeable hole on the described strip projected parts;
Can also be provided with the strip projected parts of endless tube on the described water-permeable pipe;
Strip projected parts on the described water-permeable pipe can be formed lattice shape;
Be provided with horizontal stiffener in the described water-permeable pipe, also can be the bellows that hoop is strengthened;
Can swathe on the described water-permeable pipe and support the outer thread that covers permeatable filter layer, thread can be formed lattice pattern earlier and wrap up;
Described water-permeable pipe can be tubular type, and the rectangle cast also can be the cast that a plurality of drainage pipes are combined in a formation;
Can clog dank material in the described water-permeable pipe;
The material of described permeatable filter layer can be geotextile;
Water penetrating pipe with strip projected parts of the present invention can be provided with impervious barrier according to actual conditions on the part area, and makes the part area of water-permeable pipe of the present invention permeable.
The present invention compared with prior art has the following advantages: 1, strip projected parts plays the reinforcing rib effect: strip projected parts vertically plays reinforcing rib to water-permeable pipe, and vertical bend resistance ability of water-permeable pipe is strengthened greatly; 2, form permeable rhone effect between the strip projected parts: form rhone between strip projected parts and the strip projected parts, play the effect of band drain; 3, strip projected parts improves permeability rate greatly: strip projected parts supports the permeatable filter layer of outsourcing, the permeability rate of water-permeable pipe is greatly improved, and band drain with drainage channels for certain width, when band drain is rolled into when tubular, its water permeable area is bigger than the water permeable area of plate band drain, this is that the pipe radius that the plate of the radius ratio rhone bottom surface of the formed pipe of rhone end face forms grows the height of a strip projected parts rhone because the strip projected parts of rhone has certain altitude; 4, water penetrating pipe with strip projected parts has overcome the shortcoming separately of band drain and water-permeable pipe, brought into play advantage separately: because the rhone that strip projected parts forms on the tube wall has bigger water permeable ability, can be in short distance enter and drain in the pipe and advance water in the rhone thoroughly by permeable hole on the tube wall or seam, given full play to the high advantage separately of water permeable ability of the high and rhone of the big draining cavity drainability of pipe, and overcome the water permeable ability of water-permeable pipe with holes low with the low shortcoming of drainability of band drain with drainage channels; 5, increased infiltration pressure reduction, improved drainage efficiency: the permeable efficient of well-known water-permeable pipe is to be decided by the inside and outside water pressure difference of pipe, because advancing water in the rhone thoroughly can be in short distance enter in the pipe by permeable hole discrete on the tube wall or seam and drains, therefore can there be pressure differential in the outer infiltration of the rhone of raised item formation and permeatable filter layer all the time, extraneous infiltration can be infiltrated in the rhone endlessly and enter in the water-permeable pipe and be drained, certainly rhone also can be arranged part water, thereby permeable efficient and drainage efficiency are further improved; 6, quicken the infiltration effect: when the water in the rhone flows in the gutter by permeable hole or seam, can form certain suction around hole or the seam, quicken the infiltration of extraneous infiltration; 7, drainability is insensitive to compressive strain: when the permeatable filter layer that covers on the rhone that raised item forms is compressed, to the almost not influence of its drainability, not only there is not any influence, on the contrary owing to water permeable ability slightly being strengthened, because draining mainly is at the pipe internal drainage with increasing of extraneous contact area.And for drainage channels band drain, how many permeatable filter layers is compressed between rhone, and how many its drainabilities just reduces, if permeatable filter layer is compressed to and is attached on the rhone base plate, then its drainability will total loss; 8, cost can reduce significantly: the present invention can effectively utilize bamboo to make water penetrating pipe with strip projected parts, thereby the cost of water-permeable pipe is reduced significantly; 9, help the connection of water-permeable pipe; 10, the loaded down with trivial details operation that original water-permeable pipe needs a lot of connectors has been saved in method of attachment of the present invention, and body itself can directly connect, and is very convenient.
