In article the question of what it is better to use as the filtering cloth which will be required if for arrangement of stormwater drainage system the drainage pipe 110 in the filter is used will be considered: geotextiles or coir fiber. The main kinds of pipes used for the organization of drainage system, feature of their choice and application on the country site and also quotations on purchase of expendables for construction will be considered.
Types of drainage pipes for withdrawal of underground waters: price and classification
Any country site irrespective of whether it will be used for cultivation of vegetable cultures or it is acquired under building for residential building, needs laying of drainage system. This system represents the extensive pipeline put under the surface of soil and performing function of the removing communications transporting storm waters out of borders of the site.
Elements of such removing systems first of all are classified by material type.
The modern range of pipes is divided into the groups including the products made on basis:
- ceramics (the pipe having perforated surface);
- asbestos cement.
Pay attention! Use of pipes for drainage and stormwater drainage system is obligatory if you want to keep base part of the house. Quite often storm waters waterlog cellars with preservation, cellars and the basis of residential unit, provoking development of dampness and fungus, forming of cracks and other damages.
The price of pipes for stormwater drainage system depends on material of production, diameter, length and other parameters. Asbestos-cement and stoneware is practically not used today because of large number of shortcomings in comparison with their plastic analogs.
The main lack of asbestos-cement pipes in addition to low utilization properties — their ponderousness. Compare data from this table with the prices of retail of drainage pipes of 110 mm and more from plastic to feel difference between these materials.
Drainage pipe 110 in the filter: geotextiles and coir fiber
Despite the extensive choice of the sizes, drainage pipes 110 in the filter are used most often at laying of storm system of the sewerage and drainage. The filtering material increases overall performance of all system.
Use of drainage pipes 110 with the geotextile filter or other option of the filtering material allows to detain large garbage, grains of sand and small particles of dirt. Having bought such products for the organization of drainage system, you will significantly reduce the speed of internal silting and will increase pipeline life cycles.
For wrapping of pipes the special cloths representing the nonwoven fabric having hygroscopic properties are usually used. Cloths are divided into groups on type of material which can be natural or artificial.
Pay attention! The efficiency of the filter is based on its flow capacity calculated in microns. On this indicator it is possible to calculate the particle size which the filter is capable to detain: 1 microns = 0.0001 cm. The highest flow capacity at the straw filter – 12000 microns, possesses the lowest polyester – 180-240 microns.
Among consumers drainage pipes in geotextiles and coir fiber are considered as the most popular. Geotextiles at the same time as the filtering material have flow capacity in the range of 450-700 microns. Most often it is applied on clay and sandy soils. Thanks to excellent operating ability, this kind of covering on pipes is not exposed to decomposition.
The coefficient of flow capacity equal 700 microns is inherent in the products enveloped by coir fiber. Such pipeline is usually laid in sandy, agricultural types of soil and also peat. Unlike the previous option, material gives in to decomposition.
Coir fiber and geotextiles: the prices of drainage pipes in the filter of 110 mm
Geotextiles represent nonwoven, and in rare instances the woven cloth executed on the basis of threads from polyair or polypropylene. Options of products where both kinds of these threads are used meet.
Geotextiles are widely used in medicine and production of pieces of furniture for the house, however this type of material has found the most extensive application in construction. Many producers of drainage pipes have already estimated advantages of geotextiles therefore the most part from them gradually refuses use of coir fiber and other filters.
Helpful advice! The low price of drainage pipe 110 for running meter – one of powerful advantages of the products enveloped by geotextiles. Use this favorable property to save expenses on construction of drainage system.
Advantages of pipes to stormwater drainage system in geotextiles: material properties
The price of drainage pipe of 110 mm in the geotextile filter – not the only advantage of products.
This option of material has also other advantages:
- the high steam permeability promoting uniform distribution of air and interfering development of harmful microorganisms;
- resistance to rolling down, damage or flaking;
- the increased resistance to influence of high temperatures;
- low indicator of combustibility;
- invulnerability to influence of insects and other live organisms which habitat is the soil;
- ability to effectively perform the functions throughout long term;
Pay attention! If you decide to buy drainage pipes for withdrawal of underground waters with the geotextile filter, in the absence of essential loadings this material is capable to serve almost also long, as well as all installed system.
What else can be bought pipes for stormwater drainage system with geotextiles
Geotextiles are perfectly combined with any kinds of drainage pipes. But complete with polymeric products it is capable to bring the maximum quantity of advantages.
Polymeric communications can be made of different raw materials:
At sale there are also plain, perforated and corrugated pipes. At the same time depending on constructional features distinguish drainage pipes two-layer and single-layer.
Features of drainage corrugated pipes in the filter geotextiles of 110 mm
Corrugated products have uneven ridge surface. Such pipes are issued with the special openings performing function of the filter. They perfectly are suitable for the organization of drainage systems and the stormwater drainage system located under the surface of the soil.
Helpful advice! Use properties of corrugated products for forming of the pipeline of irregular shape with turns. Thanks to flexible structure, these pipes allow to refuse application of fitting when mounting system. Besides they provide high-quality and simple connection with wells.
The majority of corrugated products is made using polyvinylchloride or low-pressure polyethylene. They have the special marking allowing to be guided quickly in assortment.
If you intend to buy drainage pipe for the construction, corrugated products can be both with the filter, and without it.
Drainage pipes in geotextiles: how to stack the pipeline by rules
Observance of all rules of technology of laying of the pipeline assumes right choice of materials. If you are mistaken at the initial stage, work should be redone.
Before buying pipes for drainage ditch and other elements of system, it is necessary to make predesigns. Important role is played by indicator of rigidity and flexibility. Specialists recommend to buy rigid pipes for the organization of the superficial pipeline while for mounting of the buried system it is better to take flexible options of products.
The pipes having nonflexible design are characterized by high rate of ring rigidity. He points to extent of deformation of product which can arise in case of strong mechanical influence.
Pay attention! Nonflexible pipes have the sizes within 6-12 m. While flexible options of products can have length about 40-50 m.
Ring rigidity (interpretation of markings on pipes):
|Digital value, SN||Maximum length of burying, m|
|16||more than 10|
Nonflexible pipes keep durability even in case of soil shift. The expenses connected with need to buy additional nodal parts for the organization of turns of the pipeline belong to shortcomings of similar designs. T-couplers for drainage pipe of 110 mm, branches, couplings concern them. Producers offer the nodal parts suitable under the main diameters of products: 110, 160, 200, 250 and 315 mm.
Features of laying of drainage pipes with geotextiles
In the course of transportation of pipes it is necessary to observe accuracy as well as at their mounting. If for any reason material sustains even single damage, in the future this pipe section will be exposed to continuous contamination, and the procedure of drainage will be violated and will become uneven.
Many producers release pipes with cover in the form of geotextiles. It substantially facilitates mounting process. The technology of installation of system supposes also independent wrapping of products cloth which can be bought separately.
Not all types of geotextiles which are available on sale can pass water therefore not each kind of material is suitable for laying of drainage pipes the hands. Suitable option are the polypropylene cloths received in the needled way and consisting only of monothreads.
Rules of treatment of geotextiles:
- it is better to carry out unpacking of geofabric at the latest moment as influence of ultraviolet reduces utilization properties of material. It is for the same reason recommended to perform all works with cloth very quickly;
- the trench has to be in advance prepared, cleaned, have smooth edges. Thanks to it you exclude any probability of damage of geofabric in the course of laying of the pipeline;
- material keeps within most freely, but at the same time on its surface there should not be waves and folds;
- geotextiles should be cut on cloths of the suitable size in advance. They have to block drainage course around pipe with an overlap (0.3-0.6 m);
- material needs to be filled up with crushed stone at once. That in the course of tamper of embankment not to damage geofabric, thickness of layer has to be not less than 0.25-0.3 m.
When the cloth is wrapped, its edges are fixed thanks to the return filling of ditch with sand or the soil. For the rest the work technique with cloth does not differ from normal mounting of storm system with already enveloped pipes.
