TUBE WITH PLASTIC VERTICAL DRAIN AND METHOD OF SOFT SOIL CONSOLIDATION USING TUBE WITH PLASTIC VERTICAL DRAIN

摘要

A pipe with mellow soil and a plastic vertical sewer of an improved method are arranged to raising problem, such as the droning or loss of discharge capacity, it is by installing a plastic vertical sewer with the pipe in the earth and excluding water by pipe, it reduces cost and water is excluded and using atmospheric pressure as load by a pipe, shorten one period merged by rapidly excluding water, is loaded compared with natural drainage by banking. One plastic vertical sewer (30) is formed the outside of a filter (10b) for internal or existing plastic vertical sewer by one pipe (40) of addition, and wherein the bottom of pipe is made of the filter (40a) for preventing a pipe of the influx of grogs and fixed discharge efficiency. One improved method of mellow soil includes the following steps:: by a mandrel shoes (20) to the plastic vertical sewer end that joined a pipe, penetrating joined the plastic draining belt of the pipe in the earth and is installed to prescribed depth, use a shell, shell is drawn then up, so that manufacturing plastic vertical sewer stays in the earth; The pipe of connection plastic vertical drains to a drain pipe (40b) above the ground, and manufacture drain pipe is against a sump (80) and generates negative pressure to pipe, excludes underground water by pipe and is added to plastic vertical sewer.
