Water penetrating pipe with strip projected parts and connection methods

Abstract

A pervious pipe for dewatering from soft foundation, soil, or earth structure is composed of the osmotic filer layer and the pipe with pervious holes or slits, and features that on said pipe there are convex strips for forming the drainage channels between adjacent convex strips. Its advantages are high water permeability and high dewatering efficiency.

Description

1) Technical field [0001] The invention relates to a permeable pipe for eliminating water seepage. Two), background technology [0002] At present, in civil and agricultural projects, it is often necessary to drain the interior of soil or structures, such as lowering the groundwater level, intercepting and draining groundwater, and drainage of soft foundations. In these drainage projects, a drainage core board with a drainage groove is commonly used, and the drainage board is composed of a permeable filter layer (such as figure 1 as shown, Picture 1-1 for figure 1 sectional schematic diagram), the disadvantage of this kind of drainage board is that under the external earth pressure or the pressure of other construction vehicles acting on the soil, the drainage channels between the drainage grooves are often compressed, such as Figure 1-2 As shown, the deeper the drainage board is buried, the greater the external load, the greater the compression, the smaller the drainag...

Problems solved by technology

In these drainage projects, a drainage core board with a drainage groove is commonly used, and the drainage board is composed of a permeable filter layer (such as figure 1 as shown, Picture 1-1 for figure 1 sectional schematic diagram), the disadvantage of this kind of drainage board is that under the external earth pressure or the pressure of other construction vehicles acting on the soil, the drainage channels between the drainage grooves are often compressed, such as Figure 1-2 As shown, the deeper the drainage board is buried, the greater the external load, the greater the compression, the smaller the drainage space of the drainage channel, and the smaller the drainage capacity

The principle of drainage is: external seepage penetrates into the permeable pipe through the holes on the permeable pipe to drain water. In order to ensure the strength of the pipe itself, the opening rate of the perforated pipe is generally less than 10%. Therefore, the external seepage penetrates into the permeable pipe through the holes of the permeable pipe The efficiency is extremely low, although there is a large drainage pipe cavity, it cannot play its due role

In addition, because there are more permeable holes or seams on the perforated permeable pipe, its strength is reduced, and the bending resistance in the longitudinal direction is greatly reduced.
