Integrated thin type plastic drainage plate and foundation vertical drainage system

Abstract

The invention provides an integrated thin type plastic drainage plate. The integrated thin type plastic drainage plate comprises a core plate and a filter film; the core plate comprises a base plate and a plurality of supporting plates; the base plate is a long-strip-shaped flat plate; the plurality of supporting plates are symmetrically arranged on the two sides of the base plate and are vertical to the base plate; the supporting plates extend along the length direction of the base plate; the filter film encloses the outer side of the core plate in an adhering mode; the thickness of the formed integrated thin type plastic drainage plate is less than 3.5 mm; the cross section of each supporting plate is shaped like an isosceles trapezoid; and the width of one end far away from the base plate is less than that of one end close to the base plate. According to the integrated thin type plastic drainage plate provided by the invention, the structure shape and the design layout of the supporting plates in the core plate are optimized, and the longitudinal water passing quantity of the integrated thin type plastic drainage plate is greatly increased on the premise of determining the chemical properties of the core plate and the filter film; meanwhile, the thickness numerical value can be controlled and the drainage efficiency of the integrated thin type plastic drainage plate is greatly improved. On the basis, the invention also provides a foundation vertical drainage system.

Description

technical field [0001] The invention relates to the technical field of soft foundation material equipment, in particular to an integral thin plastic drainage board and a foundation vertical drainage system. Background technique [0002] Plastic drainage board (belt), its cross-sectional structure usually has various shapes such as wave type and harmonica type. In the middle is an extruded plastic core plate, which is the skeleton and channel of the drainage belt. Its cross section is parallel cross, and the two sides are wrapped with non-woven geotextile as a filter layer. Drainage is a good vertical channel for silt, silty soil, flush fill soil and other saturated viscous and miscellaneous fill soils to be treated with drainage consolidation method for soft foundation, which greatly shortens the consolidation time of soft soil. Generally, the one with a width of 10cm is called a drainage belt, and the one with a width of not less than 100cm is called a drainage board. [...
