Characteristics of the trench for buried plastic pipes

Realization of the trench It will be excavated up to the line of the soil provided that the soil is uniform; if the rigid elements are not covered such as stones, rocks, old bricks, etc., it will be necessary to excavate below the soil to perform the following filling. […]

The need for systems of integrated plastic pipes

The transformation of the plastic materials by extrusion (pipes) or by injection (fittings) allow us working with very tight manufacturing tolerances that make it easy the tightness of the different elements of plastic material which are part of a water network (sewer, supply, etc.). Such small tolerances can’t be got with other kinds of materials, for example of cast concrete. […]

Refurbishment of irrigation channels with plastic pipes

The American crab builds its shelters in the ditches of soil, producing its damage. We can also find concrete ditches in bad state and in many other cases, the proliferation of algae which obstructs the conductions by reducing the flow and the functionality of the outlets. […]

More about the characteristics of the trenches for buried plastic pipes

I believe that it is very interesting what was commented by JUAN ANTONIO PEÑA MARRUFO, Design Engineer, within the group of LinkedIn AIDT (Spanish Association of Engineers and Designers of Pipes) so here I reproduce the text, extended with some image that I have looked for this occasion. The comment is related to the published posts about trenches and their supports and that you can see in: […]

Vacuum sewerage systems outside buildings

The Vacuum Sewerage Systems are mainly used in the areas where the use of gravity systems is too expensive or in environmentally sensitive areas. They are reliable and flexible systems, and normally cheapest than the alternative systems in difficult areas. The infiltration and exfiltration are not produced in the vacuum systems. These systems are generally in coastal areas with a high rate of water and flat surface or in other areas where it is too difficult or expensive to install a [...]

AseTUB Card. The Quality Mark of the Installer of plastic pipes

The most important factor The most important factor in an installation of plastic pipes is the QUALITY OF THE INSTALLATION, that is, the result of having performed according to the normative and procedures of good practice applicable in each case, for this it is essential to know them through a specific training. There is no point in having a good pipe if we install it incorrectly. […]

2) Hydraulic dimension of the sewerage network

Slopes The slopes will be adapted, as far as possible, to the topography of the area. Normally it is taken the general rule that the slope must not exceed 4 m/km (4 o/oo), but sometimes it results very difficult to keep it. It is frequently used drop shafts or rapids to reduce the slope, but when it is not possible, it is necessary to provide abrasion resistant materials. […]

1) Hydraulic Dimension of the Sewerage Network

Previous criteria Normally, the pipes of the sewerage networks of waste waters, work at partially filled section and in a system of flow free, entering in charge at a certain period of time, in determine conditions of simultaneously or of excess of flow over the design ones and in situations of cleaning or unblocking under pressure of the conducts. […]

Structured pipes for sewerage without pressure

Being: SN =    Nominal Stiffness (kN/m2) E    =    Coefficient of elasticity (N/mm2) I     =    Moment of inertia (mm4/mm) Dm =    Medium Diameter (mm) Structured pipes They are products that have an ideal design, regarding to the quantity of used material to comply with the physical and mechanical requirements according to the normative: […]
