An improved structure for a pile of Sand mold for vertical drainage and Poor Soil Drainage reinforcing Structure formed by such a device to incorporate the latter 3-99Zo a wrapper for this structure, and an apparatus for driving the same Soil

摘要

It discloses a Drainage structure and a device for placement of the same to the reinforcement of weak soil, and the devices which are used in the development of drainage.The Invention provides a Drain casing that has a part and a part of reinforcement, as well as unaenvoltura rectangular drainage.Furthermore, The Invention provides the Disclosure of a Drainage structure and a device placement in which the effective Drainage RADIUS is Uniform.The same way, The Invention provides a Pipe Guide To Bury the polygonal envolturasin produce Twisting one of the envelope,And a Drive device to install the drainage granprofundidad perpendicularly to a weak Soil without any Distortion of the Housing Guide.In this way, the device placement of drainage and Drainage aparatospara form, maximize the drainage effect and accelerate the rapid subsidence.
