Embodiment Construction

[0027] The present invention will be further described below in conjunction with accompanying drawing:

[0028] Such as figure 1 As shown in , it is a schematic structural diagram of the protective structure used for the slope of the black soil erosion ditch.

[0029] The protective structure for black soil erosion ditch slope of the present invention comprises geotextile 2 laid on the groove bottom 11 and slope 12 of trench 1, and the upper and lower ends of geotextile 2 are respectively provided with upper bending part 21 and lower bending part. The upper backfill groove 33 is arranged at the connection part of the folded part 22, the slope 12 and the ground plane 13, and the lower backfill groove 34 is arranged at the groove bottom 11, and the upper bent part 21 and the lower bent part 22 are buried in the upper backfilled groove 33 and the lower In the backfill groove 34 ; the upper backfill groove 33 and the lower backfill groove 34 are respectively filled with backfill ...

Abstract

The invention discloses a protection structure for a black land erosion gully slope and a construction method. The protection structure comprises geotechnical cloth laid at a groove bottom and the slope of a groove, the upper end and the lower end of the geotechnical cloth are provided with an upper bent part and a lower bent part correspondingly, an upper backfill groove is formed in a connecting portion of the slope and a ground plane, and a lower backfill groove is formed in the groove bottom, the upper bent part and the lower bent part are correspondingly embedded in the upper backfilling groove and the lower backfilling groove; the upper backfill groove and the lower backfill groove are filled with backfill soil; the construction method comprises the steps that soil body data and water flow characteristic information of the groove are obtained, and construction preparation is conducted; the upper backfill groove and the lower backfill groove are excavated in the connecting portion of the slope and the ground plane and the groove bottom correspondingly according to the soil mass data; and the size of the geotechnical cloth is selected according to the soil body data. According to the protection structure for the black land erosion gully slope, the problem that the ditch on the black land cannot be effectively prevented from being eroded in the prior art can be solved, the structure is simple, the cost is low, and the protection effect is good.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a protective structure and a construction method for the slope of a black soil erosion ditch. Background technique [0002] Black soil is mainly distributed in Northeast China, where the climate is relatively cold, and the main plants are annual or deciduous plants. Ditches on black soil are easily affected by both running water and climate, causing serious erosion problems. [0003] Common anti-erosion methods in general areas, such as planting vegetation on slopes or hardening and pouring slopes, are difficult to apply to black soil areas. Because of the climatic factors on the black land, most of the vegetation will be killed by the severe cold in winter, and then washed away by running water after the spring thaws; and the plants in high latitudes grow slowly, so the method of planting vegetation is actually very ineffective. On the one hand, the cost of hardening...
