VAZQUEZ ORTIZ, Carlos Alejandro  e  PASTRAN BELTRAN, Carlos Gregorio. Drainage beds under the drain lines Guadalajara metropolitan area (GMA). Tecnura [online]. 2013, vol.17, n.38, pp.82-96. ISSN 0123-921X.

This paper presented a modified construction procedure for interior drainage lines and municipal network. One of the problems that affect the roads and buildings of the GMA is the failure of this structure due to tunnels in the ground support. This is caused by water leaks in the drains lines due to the water pressure flow that came from the soil piping due to the saturation of the ground support and consequently decreasing the resistance. In this paper it has been proposed the inclusion of a drainage bed, composed of a layer of pumitic sand, which could compromise the main GMA. This material develops high permeability and good resistance if it is compacted. Also, it has been included the installation of grids at certain distance to avoid the loss of fine particles due to piping. Moreover, a polyethylene layer has been added to the drainage bed, which prevents water leaking thought the ground support.
