Description

Technical Field

[0001] The utility model belongs to the field of water conservancy projects, and more specifically, relates to a repair structure for a rigid slope protection. Background Technique

[0002] The development trend of ecological revetments is gradually from functional rigid revetments to green plant-type ecological revetments; from simple planar linear distributions to multi-dimensional spatial plant belt distributions; and from simple ecological revetment engineering measures to the combination of engineering and biological measures to create biodiversity and enhance the visual beauty of the landscape. Currently, the commonly used ecological revetments mainly include: interlocking block grass planting slope protection, ecological block retaining walls, ecological bin sheet piles, etc. However, some existing revetments are still membrane bag concrete slope protection, grouted stone slope protection or plain concrete slope protection, with poor ecological properties and being extremely inconsistent with newly built ecological revetments.

The repair structure is provided with a curved landscape wall on the slope protection, and the slope protection is covered by a geotextile and a geocell on the curved landscape wall. Green plants are planted in the geocell to meet the environmental protection concept of green and low-carbon. A water and soil exchange hole is also provided on the slope protection to ensure the survival rate of the green plants.

[0004] To achieve the above purpose, the utility model provides a repair structure for a rigid slope protection, including:

[0013] The utility model provides a repair structure for a rigid slope protection, and its beneficial effects are as follows: The repair structure can repair and transform on the basis of the existing slope protection. After the transformation, green plants can be matched in the geocell, which conforms to the development concept of green and low-carbon. And during the construction of this repair structure, there is no need to set up cofferdams, and only the curved landscape wall is needed to block the impact of river water. In this way, the construction is more convenient, and the cost can be effectively controlled. In addition, water and soil exchange holes can be arranged at intervals in the existing concrete-filled fabric formwork slope protection structure, which is beneficial to the growth and survival of plants in the geocell.

[0019] The following will describe the preferred embodiments of the present utility model in more detail. Although the following describes the preferred embodiments of the present utility model, it should be understood that the present utility model can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present utility model more thorough and complete, and to be able to fully convey the scope of the present utility model to those skilled in the art.

[0020] The present utility model provides a repair structure for a rigid slope protection, including:

[0021] A curved landscape wall is arranged on the slope protection, and water and soil exchange holes are arranged at intervals on the slope protection;

[0022] A geotextile is arranged between the curved landscape wall and the slope protection, and a geocell is arranged on the upper surface of the geotextile.

[0023] Specifically, a curved landscape wall is set along the shoreline of the slope protection. The water in the river is blocked by the curved landscape wall, so there is no need to set up cofferdams during the renovation process, which facilitates construction. A geotextile is laid on the backwater side of the curved landscape wall, and the geotextile also covers the original slope protection. A geocell is set on the upper surface of the geotextile, and green plants are planted in the geocell, which can carry out greening renovation on the slope protection. In addition, water and soil exchange holes are set in the slope protection under the geocell, which can realize the water and soil exchange in the geocell and extend the survival time of the green plants.

[0024] Optionally, the curved landscape wall includes stress piles and connecting plates. The stress piles are arranged at intervals along the shoreline of the slope protection. The connecting plates are connected to the tops of the stress piles, and the backwater side of the connecting plates is connected to the geotextile.

[0025] Specifically, the construction of the curved landscape wall is to drill holes at equal intervals on the slope protection first, then arrange the stress piles and install the connecting plates on the stress piles. The connecting plates are arranged on the backwater side of the stress piles, and the connecting plates and the slope protection are connected through the geotextile. In this way, the river water passing through the curved landscape wall can be blocked, preventing soil erosion and ensuring the normal growth of the green plants in the geocell.

[0026] Optionally, the slope protection is a molded bag concrete slope protection, and the geotextile is laid at one end of the molded bag concrete slope protection close to the curved landscape wall.

[0027] Specifically, this repair structure is an improvement on the existing molded bag concrete slope protection. In addition to setting up the curved landscape wall, geotextiles are also set at the connection between the curved landscape wall and the molded bag concrete slope protection, which is convenient for subsequent installation of geocells and planting of green plants, making the repaired slope protection meet the environmental protection requirements of green and low-carbon.

[0028] Optionally, a soil covering layer is set on the upper surface of the molded bag concrete slope protection, and a geocell is set on the upper surface of the soil covering layer.

[0029] Specifically, in addition to laying the geotextile on the backwater side of the curved landscape wall, a soil covering layer and a geocell are also formed on the molded bag concrete slope protection, which can improve the anti-scouring ability and durability. By adopting the structural form of the curved landscape wall and the geotextile, it is possible to plant plants on the upper part of the existing rigid slopes such as the membrane bag concrete. The geocell can also reduce the scouring of the water flow.

[0030] Optionally, the height of the geocell is not less than 15 cm.

[0031] Optionally, the geocell is covered with planting soil, and the thickness of the planting soil is not less than 20 cm.

[0032] Specifically, the geocell is filled with planting soil, and the height of the planting soil is higher than that of the geocell, which is beneficial to the growth of the green plants.

[0033] Optionally, gravel is set in the water and soil exchange holes.

[0034] Specifically, the water-soil exchange holes can achieve the water-soil exchange between the water body and the soil in the geocell, provide a good growth environment for green plants, and through the gravel in the holes, the ability to resist water flow scouring can be improved, avoiding soil loss.
