Fixing method of sponge city sunken micro-terrain

Abstract

The invention discloses a fixing method of sponge city sunken micro-terrain. The fixing method comprises the following steps that S010, the lower portions of L-shaped reinforcing soil blocking strips are attached to a micro-terrain soil body with modeling correction completed, and the upper portions of the L-shaped reinforcing soil blocking strips penetrate lawn seams to be perpendicular to the micro-terrain soil body; S020, turf is laid to cover the lower portions of the L-shaped reinforcing soil blocking strips; and S030, soil nails are adopted for penetrating the turf to nail the L-shaped reinforcing soil blocking strips into the micro-terrain soil body. According to the fixing method, modeling steadiness of the micro-terrain soil body in sponge city building is guaranteed, and meanwhile the survival rate of new plant greening is increased.

Description

technical field [0001] The invention relates to the field of sponge city construction, and more specifically, relates to a method for fixing submerged micro-topography of the sponge city. Background technique [0002] At present, the construction of sponge cities has begun to be vigorously promoted and applied in China. There are a large number of micro-topographic structures set up in it, such as rain gardens, ecological dry creeks, and sunken green spaces. After the construction of this type of structure is completed, when the soil is not completely deposited and the root system of the vegetation is firm, it is easy to cause soil landslide loss under the action of rainwater erosion, resulting in a decrease in the survival rate of newly planted vegetation and a decrease in the overall aesthetics of the micro-topography , which has a greater impact on the construction of sponge cities. [0003] In the construction of sponge city reconstruction, a large number of micro-topog...

Problems solved by technology

After the construction of this type of structure is completed, when the soil is not completely deposited and the root system of the vegetation is firm, it is easy to cause soil landslide loss under the action of rainwater erosion, resulting in a decrease in the survival rate of newly planted vegetation and a decrease in the overall aesthetics of the micro-topography , which has a greater impact on the construction of sponge cities

[0003] In the construction of sponge city reconstruction, a large number of micro-topographic structures are mostly excavated manually and mechanically due to the construction technology. After the excavation is completed, the slope is manually repaired. In the early stage, the root system of the plants did not go deep into the soil to stabilize the soil. When the rain hits, the unstabilized soil will be washed away, resulting in the deformation of the micro-topographic soil structure and not achieving the aesthetic effect. At the same time, the lack of nutrient soil for the vegetation will reduce the survival rate of the vegetation.
