Referring to fig. 2, it is a schematic cross-sectional structure of an embodiment of the modified high polymer blind ditch pipe of the present application.
Referring to fig. 3, an exploded view of an embodiment of the present application is shown for a modified geopolymer blind pipe.
As can be seen from fig. 1 to 3, the modified high polymer blind ditch pipe provided in the embodiments of the present application includes an outer filter element 200, a geotextile 100 coated outside the outer filter element 200, an inner filter element 300, wherein,
the outer layer filter element 200 and the geotextile 100 are both cylindrical tubular structures;
the inner filter element 300 is positioned inside the outer filter element 200;
an interlayer gap 400 is arranged between the inner filter element 300 and the outer filter element 200;
a drainage channel 500 is arranged in the inner layer filter element 300;
the drainage channel 500 has a cylindrical cavity structure.
As can be seen from the above technical solutions, the modified high polymer blind ditch pipe provided in the embodiment of the present application includes the outer layer filter element 200, the inner layer filter element 300 and the geotextile 100, and the functional functions of each part are described as follows:
geotextile 100: the geotextile 100 is coated on the outer surface of the outer-layer filter element 200, and water flow of surrounding soil layers can enter the blind ditch through the good air permeability and water permeability, so that soil particles, fine sand, small stones and the like can be effectively isolated, and the stability of water and soil engineering can be kept.
Outer filter element 200: the outer-layer filter element 200 is of a cylindrical tubular structure and has certain structural strength, so that the modified high polymer blind ditch pipe is prevented from being extruded and deformed by a soil layer after being arranged underground; meanwhile, the outer filter element 200 provides a passage for water in the surrounding soil layer to enter the modified high polymer blind ditch pipe.
Inner filter element 300: the inner filter element 300 is positioned inside the outer filter element 200, the interlayer gap 400 is formed between the inner filter element 300 and the outer filter element 200, and the inner filter element 300 can move freely in the middle of the outer filter element 200; the inner filter element 300 is provided with the drainage channel 500 therein, and the inner filter element 300 provides a function of allowing moisture to enter the drainage channel 500 from the outer filter element 200.
The drainage channel 500: the water filtered by the outer filter element 200 and the inner filter element 300 is collected by the drainage channel 500, and the drainage channel 500 is a cylindrical cavity, so that the water can be discharged orderly and rapidly by using the gravity of the water.
Optionally, in this embodiment, the inner filter element 300 is a cylindrical tubular structure, and the outer diameter of the inner filter element 300 is smaller than the inner diameter of the outer filter element 200.
Further, since the inner diameter of the outer filter element 200 is constant, the outer diameter of the inner filter element 300 is inversely proportional to the size of the interlayer space 400. When the outer diameter of the inner filter element 300 is small, the interlayer gap 400 is too large, which leads to the failure of the inner filter element 300; on the contrary, when the outer diameter of the inner filter element 300 is close to the inner diameter of the outer filter element 200, the interlayer space 400 is too small, which results in a narrow movable space of the inner filter element and low drainage efficiency. In this embodiment, the outer diameter of the inner filter element 300 is optimized to 3/4 of the outer filter element 200.
As can be seen from the above technologies, the working principles of the modified high polymer blind ditch pipe provided in the embodiments of the present application under the general condition and the special condition are respectively as follows:

In special cases.
When the water amount entering from the modified high polymer blind ditch pipe in the peripheral direction is different and the water amount of one side is larger, the water contained in the side cannot immediately pass through the inner filter element after passing through the outer filter element, and the water is continuously collected between the inner filter element and the outer filter element, so that the inner filter element gradually moves to the opposite side, and meanwhile, the interlayer gap moves to the side; this part of the water in the interlayer space will on the one hand move in the interlayer space in the discharge direction and on the other hand successively pass through the inner filter element into the drainage channel while moving in the discharge direction.

Optionally, the porosity of the inner filter element 300 is greater than the porosity of the outer filter element 200.
Further, because the outer diameter of the inner filter element 300 is smaller than the inner diameter of the outer filter element 200, and the porosity of the inner filter element 300 is larger than that of the outer filter element 200, the water passing through the inner filter element 300 in unit time is equal to that of the outer filter element 200, so that the water stagnation is reduced, and the water drainage efficiency is ensured.
Optionally, the thickness of the outer filter element 200 is 15-40 mm.
Further, the thickness of the outer filter element 200 is too thick, which results in slow water filtration process and affects drainage efficiency; in addition, the outer filter element needs to maintain certain strength to prevent extrusion deformation, and therefore, the thickness of the outer filter element 200 is preferably 15-40mm in this embodiment.
Optionally, the thickness of the inner filter element 300 is 10-20 mm.
Further, in this embodiment, the thickness of the inner filter element 300 is preferably 10-20mm, which can accelerate the water passing through the inner filter element 300, and is also beneficial for the inner filter element 300 to move on the outer filter element 200, so that the interlayer gap 400 moves to the water collection position more quickly.
According to the technical scheme, the modified high polymer blind ditch pipe provided by the embodiment of the application comprises: the filter comprises an outer-layer filter element 200, geotextile 100 coated outside the outer-layer filter element 200 and an inner-layer filter element 300, wherein the outer-layer filter element 200 and the geotextile 100 are both cylindrical tubular structures; the inner filter element 300 is positioned inside the outer filter element 200; an interlayer gap 400 is arranged between the inner filter element 300 and the outer filter element 200; a drainage channel 500 is arranged in the inner layer filter element 300; the drainage channel 500 is a cylindrical cavity structure; the inner filter element 300 is a cylindrical tubular structure, and the outer diameter of the inner filter element 300 is smaller than the inner diameter of the outer filter element 200. According to the blind ditch structure provided by the embodiment, when the water amount entering from the periphery of the plastic blind ditch in a filtering mode is different and the water amount on one side is larger, the blind ditch structure can gradually move to the opposite side through the inner-layer filter element and move the interlayer gap to the side; the part of water in the interlayer gap moves towards the discharge direction in the interlayer gap on one hand, and on the other hand, the part of water moves towards the discharge direction and simultaneously enters the drainage channel through the inner-layer filter element on the other hand, the blind ditch of the structure effectively avoids the stagnation of water, enables the water to be discharged in a shunting manner, and improves the drainage efficiency.

in general. The operation principle in general is the same as that of the first embodiment, and is not described herein.
In special cases.
When the water amount entering from the modified high polymer blind ditch pipe in the peripheral direction is different and the water amount of one side is larger, the water content of the side is prone to be collected to the interlayer gap position due to relatively larger resistance of the inner layer filter element after passing through the outer layer filter element, at the moment, the inner layer filter element rotates to the direction, and the interlayer gap gradually turns to the side with larger water content; this part of the water in the interlayer space will on the one hand move in the interlayer space in the discharge direction and on the other hand successively pass through the inner filter element into the drainage channel while moving in the discharge direction.
