In order to achieve the purpose, the utility model provides a pair of anti-seepage structure at bottom of artifical stream brook, specific implementation scheme is as follows:

an artificial brook bottom anti-leakage structure comprises a ditch, wherein the bottom of the ditch is arranged in a step shape, a lower packing layer, an anti-leakage layer and an upper packing layer are sequentially arranged in the ditch from bottom to top, the lower packing layer is a sand layer with the thickness of 2.5-5cm, the anti-leakage layer is a flexible liner film layer, and the upper packing layer is a pond mud layer or a planting soil layer with the thickness of 5-10 cm; the anti-seepage layer is laid on the bottom wall and the side wall of the ditch, anchoring ditches are dug on the outer portions of two sides of the ditch, the anti-seepage layer extends into the anchoring ditches from the bottom of the ditch through the two side walls of the ditch, and heavy matter layers used for compressing the anti-seepage layer are arranged in the anchoring ditches.

As a further improvement of the utility model, the flexible liner film of the impermeable layer is a high-density polyethylene impermeable film.

As a further improvement, the transition of the step of irrigation canals and ditches bottom is circular-arc or low-angle setting, for the diapire of the irrigation canals and ditches is laminated smoothly to the barrier layer.

As a further improvement, the anchoring ditch is provided with a small angle or a circular arc shape, so that the impervious layer is smoothly laminated in the anchoring ditch.

As a further improvement of the utility model, the heavy layer is a masonry layer or at least 8cm soil layer.

Based on the technical scheme, the utility model discloses for prior art, lay the lower packing layer that comprises thickness 2.5-5 cm's sand through the bottom at the irrigation canals and ditches, lay the barrier layer that high density polyethylene prevention of seepage membrane constitutes under on the packing layer, then lay the last packing layer that comprises pond mud or planting soil in the barrier layer top, form artificial irrigation canals and ditches basement, utilize the good mechanical characteristic of high density polyethylene of barrier layer, prevent that the barrier layer from leading to the fracture because inhomogeneous settlement, the condition of seepage takes place, and the construction mode is simple convenient, construction quality detects easily, the cost is low, construction degree of difficulty and construction cost have been reduced effectively. The artificial brook stream bottom seepage prevention device has the advantages of simple structure, convenience and quickness in construction, low manufacturing cost and high seepage prevention performance, and effectively solves the problems that landscape water in the brook is lost due to seepage of the artificial brook stream bottom, at least later-stage greening is not attractive, water quality of the brook cannot be improved, and other buildings are affected.

Detailed Description

The utility model discloses an artificial brook stream bottom anti-seepage structure is explained with the attached drawing.

As shown in fig. 1, this antiseep structure is at bottom of artificial stream brook, including irrigation canals and ditches 1, 1 bottom of irrigation canals and ditches is the echelonment setting, lower packing layer 2, barrier layer 3 and the last packing layer 4 that set gradually from bottom to top have been laid in irrigation canals and ditches 1, barrier layer 3 by the outside setting of irrigation canals and ditches 1 is extended to both sides to the bottom of irrigation canals and ditches 1.

The lower packing layer 2 is a sand layer with the thickness of 2.5-5cm, and the lower packing layer 2 is evenly and flatly paved at the bottom and two side walls of the ditch 1.

The impermeable layer 3 is a flexible liner thin film layer paved by adopting a high-density polyethylene impermeable film, the impermeable layer 3 is paved on the lower packing layer 2, and two ends of the impermeable layer extend to the outside of the ditch 1.

The upper packing layer 4 is a pond mud layer or a planting soil layer with the thickness of 5-10cm, and the upper packing layer 4 is laid on the impermeable layer 3 and used for planting aquatic plants or placing stones to arrange landscapes.
