specific Embodiment approach 1

[0029] Specific implementation mode one: as figure 1 , figure 2 As shown, this embodiment discloses a material seepage control device, including a soil column test device 1, a water inlet pipe 4, a constant pressure water supply martensitic bottle 6, a water injection port 8, an electronic water gauge 9 and a data recording device 10;

[0030] The soil column test device 1 comprises a loam cake and a square layered transparent stuffing box, the square layered transparent stuffing box is set to six layers from top to bottom, each layer of stuffing box can be disassembled, and the bottom plate of each layer of stuffing box is It is a permeable board, and the six-layer packing box is sequentially laid with a protective layer 101, a sand cushion layer 102, a seepage reduction layer 103, a reverse filter layer 104, a permeable stone layer 105 and a crushed gravel block layer 106; Installed on the upper end of the stuffing box on the top layer, the upper cover is provided with ven...

specific Embodiment approach 2

[0031] Specific implementation mode two: as figure 1 , figure 2 As shown, this embodiment is a further description of specific embodiment 1. The protective layer 101 is made of gravel; ) is laid (slightly flattened and compacted); the reverse filter layer 104 is laid by fine sand (with a particle size of 0.075 mm to 0.25 mm); the permeable stone layer 105 is laid by permeable stone, and the permeable Stone (diameter is 20cm) wraps 3-5 layer along side with non-woven fabric (and fine-tunes flatness); Described crushed gravel block layer 106 is laid by crushed gravel block (particle diameter is 1.2-2.8cm).

specific Embodiment approach 3

[0032] Specific implementation mode three: as figure 1 , figure 2As shown, the present embodiment is a further description of specific embodiment two. The permeability-reducing layer 103 is made of 15% Na-based bentonite+0.25% coconut shell fiber (length 2cm)+84.75% of the test area. It is paved after mixing ordinary soil (the composite soil formed by mixing bentonite and plant fiber has good seepage reduction performance, and can also improve the unconfined compressive strength of the soil, which is beneficial to the water demand and flood discharge of the natural environment on both sides of the river. , with certain ecological benefits).

The device and the method are used for material seepage control.

Description

technical field [0001] The invention belongs to the technical field of material seepage control, in particular to a material seepage control device and an application method thereof. Background technique [0002] Engineering seepage reduction technologies are mainly divided into vertical seepage reduction and horizontal seepage reduction. At present, the main horizontal seepage reduction measures in the world can be divided into river hardening treatment seepage reduction, composite geomembrane seepage reduction, clay seepage reduction, and bentonite waterproof blanket seepage reduction. And five kinds of composite soil materials for reducing seepage. Composite soil seepage reduction is a method of sandy soil seepage reduction formed by the use of various materials, such as triple soil seepage reduction, cement submerged soil seepage reduction and curing agent soil seepage reduction, etc., mainly depends on the properties of additives and natural sand and gravel soil materia...
