Problems solved by technology

After water is discharged from the drain hole on the concrete wall, it is easy to efflorescence along the wall surface, which affects the durability of the structure and affects the appearance; the scattered flow of the concrete drain hole is easy to cause erosion of the backfill soil in front of the retaining wall, which will cause damage over time. Part of the backfill soil in front of the wall is lost, the foundation at the toe of the wall is softened, and the bearing capacity is reduced

Embodiment Construction

[0040] In order to make the above and other objects, features and advantages of the present invention more comprehensible, preferred embodiments of the present invention will be described in detail below together with the accompanying drawings.

[0041] The invention provides a retaining wall for constructing a sponge city, the section of which is as follows figure 1 As shown, the retaining wall is a concrete structure wall, and a greening structure is arranged on the outside of the retaining wall. On the water filter layer 4, plants can be planted in the soil layer 3, a layer of permeable geotextile is arranged between the soil layer 3 and the water filter layer 4, and the wall in the flower tank 2 has the outlet of the water delivery pipe 15 and the water collection pipe 16 entrance.

[0042] The retaining wall may include one or more rows of planters 2, so that when rainwater overflows the top of the retaining wall, rainwater can be collected.

[0043] Planter 2 is a rein...

Abstract

The invention relates to a retaining wall for constructing a sponge city and a construction method thereof. The retaining wall is a concrete structure wall, a solar power system is arranged on the top of the retaining wall, flower troughs are arranged on the outside of the retaining wall, and the wall A water delivery pipe, a water collecting pipe and a water suction pipe are arranged inside, a water storage tank is arranged under the wall body, a water pump is arranged in the water storage tank, the water pump is connected with the water suction pipe, and the water storage tank is connected with the urban drainage system at the same time. The invention makes full use of solar energy, which is a huge amount of energy, has ingenious design and convenient construction, and is used for building an intelligent sponge city.

Description

technical field [0001] The invention belongs to the technical field of urban drainage and waterlogging prevention and greening landscape, and in particular relates to a retaining wall for constructing a sponge city and a construction method thereof. Background technique [0002] There are many retaining structures in today's cities, the most important ones are retaining walls, which are mostly concrete components and have a cold and hard appearance. After water is discharged from the drain hole on the concrete wall, it is easy to efflorescence along the wall surface, which affects the durability of the structure and affects the appearance; the scattered flow of the concrete drain hole is easy to cause erosion of the backfill soil in front of the retaining wall, which will cause damage over time. Part of the backfill soil in front of the wall is lost, the foundation at the toe of the wall is softened, and the bearing capacity is reduced. [0003] Sponge city is a new generat...
