Embodiment Construction

[0024] The idea, specific structure and technical effects of the present invention will be further described below in conjunction with the accompanying drawings, so as to fully understand the purpose, features and effects of the present invention.

[0025] Such as figure 1 Shown, the construction method of reinforced soil drainage composite type slope protection of the present invention, concrete construction steps are as follows:

[0026] Step 1: Excavate the slope to be protected. The slope body to be protected is excavated into at least one graded slope, and the slope protection structure 10 is correspondingly laid outside the graded slope; platforms 20 are arranged between the graded slopes, and the width of the platform 20 is at least 2m. A platform intercepting ditch 21 is set on the platform 20.

[0027] The present invention adopts a multi-level slope protection structure and widens the platform width between the multi-level protection slopes, and sets up multi-level...

Abstract

The invention discloses a construction method for a reinforced soil drainage composite revetment structure. The method includes the following steps that first, a slope body to be protected is excavated; second, the revetment structure is laid on the surface of the excavated slope body and comprises a gravel drainage layer, a reinforced soil layer and a slope protection layer, in particular, the gravel drainage layer is laid on the surface of the slope body, the reinforced soil layer is arranged outside the gravel drainage layer, then a slope toe wall is adopted for reinforcing the bottom of the slope body, and the slope protection layer is laid outside the reinforced soil layer ultimately; and third, after the slope protection structure is laid, green plants are planted on the slope protection layer. Compared with the prior art, the construction method has the advantages of being simple in structure, convenient to construct, economical in cost, excellent in protecting effect and the like.

Description

technical field [0001] The invention belongs to the technical field of geotechnical engineering, and in particular relates to a construction method for reinforced soil drainage compound slope protection. Background technique [0002] Expansive soils such as red clay have the characteristics of water absorption and shrinkage, and expansive soil slopes are prone to cracks, and the formation of cracks is the main factor affecting slope instability. When the expansive soil slope encounters heavy rain and other weather, it is very easy to cause geological disasters in the deep cutting section. Expansive slopes often suffer from disasters such as collapses and landslides due to weather and other reasons. Once they occur, they will have a great impact on the lives of local people and construction projects. Therefore, it is very necessary to carry out protective treatment on the expansive slope to avoid damage such as slope instability. However, the existing protection structures ...
