Problems solved by technology

However, this method is only suitable for sandy slopes. Due to the small particles and poor permeability of clay slopes, it is difficult for cementing fluid to penetrate into the slope, and the protective layer formed is not effective.

Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0024] like figure 1 As shown, a kind of scour-resistant and permeable ecological protective surface of cohesive soil slope includes cohesive soil slope 1, sand and gravel protective layer 2 cemented on the surface and bottom of cohesive soil slope 1, and the cohesive soil slope 1 slope Vegetation that grows through the sandstone protection layer 2.

[0025] Vegetation is common grass5.

[0026] The sand and gravel protective layer 2 is formed by cementing the mixture of sand and gravel through the cementing solution 10. The thickness of the sand and gravel protective layer 2 on the slope is 1 cm to 2 cm, and the thickness of the sand and gravel protective layer 2 at the bottom of the slope is...

Abstract

The invention discloses a scouring-resistant permeable ecological protection surface for cohesive soil slopes and a construction method thereof. The protection surface comprises a cohesive soil slope,sand-gravel protective layers cemented to the surface and the bottom of the cohesive soil slope and vegetation growing through the sand-gravel protective layer from the surface of the cohesive soil slope. The invention also discloses a construction method of the protection surface at the same time. The protection surface disclosed by the invention has the advantages that the sand-gravel protective layers, clay and the vegetation form an integer so as to form an ecological slope with high drainage property and strong soil conservation capacity; compared with slope protecting structures such asconcrete and the like, the protection surface disclosed by the invention is ecological and friendly to environment, short in construction period and low in cost; compared with a plant slope protecting layer, the sand-gravel protective layers have the advantages of certain scouring resistance, better drainage property and stronger ability to resist harsh environment; in addition, the problem thatmicrobial cementation technology is difficult to be applied to clay slopes is solved; and the construction process is simple and the quality is controllable.

Description

technical field [0001] The invention relates to a scour-resistant and permeable ecological protective surface of a cohesive soil slope and a construction method thereof, belonging to the technical field of slope care. Background technique [0002] Slope protection is a very important project in various engineering fields. Common slope protection methods include engineering slope protection and plant slope protection. Engineering slope protection includes masonry slope protection, riprap slope protection, concrete slope protection, etc. Although this slope protection method has high reliability and strong adaptability, it has high cost, long construction period, and high requirements for raw materials. Plant slope protection is to protect and reinforce the surface of the slope by planting plants and using the interaction between plants and rock and soil (root anchorage), so that it can not only meet the requirements for the stability of the slope surface, but also restore th...
