Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a kind of net drainage device for soil, in which a groove is provided in a drainage plate, and a large amount of rainwater or groundwater in the soil structure can be drained to immediately reduce the earth pressure, thereby improving the stability of the soil structure. The present invention relates to a type of net drainage device for ground processing, which is maintained to prevent ground movement.

[Prior art]

 In the soil structure formed by the conventional earth process net and the earth filling used in many earth processes, the arrangement of the drainage network will increase or decrease the earth pressure in the soil structure and stabilize the earth filling. And severely affect ground movement. The drainage networks currently used in the civil engineering industry to effectively receive and discharge rainwater and groundwater in soil structures are shown in Figs. 5 to 7, where the drainage network 5 is A plurality of drainage strips 50 are joined so as to intersect vertically and horizontally. As shown in FIGS. 6A and 6B, the drainage strip 50 includes one concave strip 511, two bundles of high tension polyester fiber bundles 512, 513, and a drainage zone 514. The concave strip 511 is formed by using a metal mold to cover the outer layer of the two bundles of high tensile force resin fiber bundles 512, 513, which are held at an appropriate distance in the middle by the polymer 501. . At the center of the upper surface of the concave strip 511, there is one groove 502 in the longitudinal direction, and the drainage strip 514 is formed by inserting a drainage zone 514 into the groove 502 using a device. The drainage zone 514 is a kind of mesh, and is made porous, and has a function of absorbing and discharging rainwater and groundwater in the soil structure as needed.

The above-mentioned conventional mesh net drainage device for soil absorbs rainwater and groundwater in a soil structure by a mesh hole of a drainage zone 514 fitted in a groove 502 provided at the center of a concave strip 511. And discharges. However, the space of the net hole of the drainage zone 514 is considerably limited, and it is not possible to immediately discharge a large amount of rain or groundwater in the soil structure caused by heavy rain or the like. When the water content reached saturation, the frictional force between the drainage network and the soil decreased relatively, and the earth pressure increased rapidly, causing the relative movement and collapse of the soil in the soil structure.

[Problems to be solved by the invention]

 In view of the above-mentioned drawbacks of the conventional drainage network for soil, the present invention has an object to provide a kind of drainage device for soil which can effectively discharge a large amount of rainwater or groundwater in a soil structure efficiently. And

Specifically, an object of the present invention is to provide a kind of net drainage device for soil in which a drainage plate is provided with a drainage tank type groove having a maximum drainage space.

Another object of the present invention is to provide a kind of drainage tank type net drainage device for soil which is effective for providing a drainage layer on a drainage plate and enhancing the stability of the soil structure. Yes.

[0007]

[Means for Solving the Problems]

 The invention according to claim 1 is directed to a net drainage device for soil composed of a plurality of drainage strips 10 and a plurality of connecting strips 20 joined so as to intersect, wherein the drainage strips 10 are one concave strip. 11, composed of a plurality of high tensile strength polyester fiber bundles 12 and one drainage layer 13, the plurality of high tensile strength polyester fiber bundles 12 are buried longitudinally in the concave plate strip 11, A plurality of grooves 111 are provided in the longitudinal direction on the upper surface of the concave plate 11, and the drainage layer 13 is joined on the concave plate 11 so as to cover the upper surface of the concave plate 11. The recessed groove 111 of the plate strip 10 has the largest drainage space, and has the above-mentioned configuration, which is a net drainage device for soil.

[0008]

[Embodiment of the invention]

 The mesh drainage device for soil of the present invention is formed by joining a plurality of drainage plates and a plurality of connecting plates so as to intersect, wherein the drainage plate includes one concave plate and a plurality of drainage plates. A high tensile tensile strength polyester fiber bundle and one drainage layer are included, and the plurality of high tensile tensile strength polyester fiber bundles are provided in a concave strip, and are longitudinally disposed on the upper surface of the concave strip. A concave groove is provided, and a drainage layer is joined so as to cover the upper surface of the concave plate, thereby forming the drain plate. The grooves in the drainage strip have the largest drainage space and immediately and efficiently discharge a large amount of rainwater or groundwater in the soil structure, maintain the stability of the soil structure, and prevent ground movement and collapse. .

【Example】

 As shown in FIGS. 1 to 4, the net drainage device for soil 1 of the present invention is formed by joining a plurality of drainage strips 10 and a plurality of connecting strips 20 so as to intersect. As shown in FIGS. 2, 3, and 4, the drainage strip 10 is composed of one concave strip 11, a plurality of polyester fiber bundles 12 having high tensile strength, and one drainage layer 13. I have. The plurality of high tensile force polyester fiber bundles 12 are provided in the concave plate 11, a plurality of concave grooves 111 are provided on the upper surface of the concave plate 11, and the drainage layer 13 is formed in the concave plate 11. It is joined to the upper surface of The plurality of grooves 111 of the drainage strip 10 have the largest drainage space and can smoothly discharge a large amount of rainwater or groundwater in the soil structure, and maintain the stability of the soil structure.

[Effect of the invention]

 5 to 7 show an embodiment of a drainage network currently used in the civil engineering industry, in which a drainage zone 514 fitted in a middle groove 502 of a concave strip 511 is provided. The space is slightly the space of the net hole between the groove 502 and the drainage zone 514, so that the amount of water that can be drained in a unit time is considerably limited, and the drainage speed is also affected by the bent net hole. It was not possible to quickly drain large amounts of rainwater or groundwater from soil structures. On the other hand, the drainage strip 10 of the present invention has a drainage layer 13 joined to the upper surface of a concave strip 11 having a plurality of high tensile strength polyester fiber bundles 12 therein. The drainage space of the groove 111 in the drainage strip 10 is larger than the drainage network embodiment used in the current civil engineering industry shown in FIGS. 5 to 7. That is, in the conventional drainage network, the drainage band 514 is fitted in the entire space of the groove 502 of the concave strip 511, whereas in the present invention, the plurality of grooves 111 have the largest drainage space, Drainage can be performed smoothly by increasing the amount of drainage per unit time.
