Plastic drainage plate and foundation heating circulation system formed by end connectors of plastic drainage plate

Abstract

The invention discloses a plastic drainage plate and a foundation heating circulation system formed by end connectors of the plastic drainage plate. The foundation heating circulation system comprises the plastic drainage plate, wherein the plastic drainage plate comprises a core plate and a filter membrane wrapping the core plate; the core plate is formed by connecting a plurality of relatively independent channel pipes side by side; drainage channels are formed in the space between the filter membrane and the outer walls of the channel pipes of the core plate; internal channels are formed in internal channels of the channel pipes; the bottom end of the plastic drainage plate is connected with the bottom end connector; all the channel pipes of the plastic drainage plate communicate with an inner cavity of the bottom end connector; the top end of the plastic drainage plate is connected with the top end connector; the interior of the top end connector is divided into two independent inner cavities; the two inner cavities are provided with leading-out connectors correspondingly; and hot water enters one half of the channel pipes of the plastic drainage plate from a circulation water inlet of the top end connector, flows into the inner cavity of the bottom end connector along the channel pipes, then enters the other half of the channel pipes, circulates back to the top end connector from bottom to top and is drained out of a circulation water outlet of the top end connector.

Description

technical field [0001] The invention belongs to the technical field of plastic drainage boards and soft soil foundation drainage, and in particular relates to a foundation heating circulation system composed of plastic drainage boards and their end joints. Background technique [0002] The plastic drainage board (belt) is composed of a plastic core with a longitudinal drainage channel and a permeable filter cloth. The core is generally made of polyethylene, polypropylene and other plastics, and the permeable filter cloth is generally polyester, vinylon and polypropylene. Short fiber impregnated non-woven geotextile or long fiber hot-melt non-woven geotextile. The drainage board can collect the water in the surrounding soil whose water pressure is higher than that in the board into the board and discharge it to the set place, so as to reduce the moisture content in the surrounding soil, so as to improve the strength of the soil and reduce the deformation of the soil .
