Cast-in-place greening concrete construction method for inland waterway

Abstract

The invention discloses a cast-in-place greening concrete construction method for an inland waterway, which comprises the following steps of: 1) flattening and compacting a slope surface to be protected, and ensuring that the compaction degree is more than 90%; (2) aggregate, cement, water and a special additive are put into a stirring machine in sequence on site to be mixed to prepare greening concrete, the greening concrete is evenly poured on the slope surface according to the specified thickness, and surface holes are formed through a hole forming machine; (3) after maintenance is conducted for 5-7 days, planting soil and a water-retaining agent are scattered in surface holes and the slope surface; 4, grass seed sowing or turf laying is conducted on the part above the normal water level of the side slope, according to different gradients, slope lengths and soil types, the appropriate laying thickness and surface hole parameters of the cast-in-place greening concrete are provided, cost reduction and labor saving are facilitated, filtering and erosion of side slope soil can be reduced, water and soil flowing water can be reduced, and damage such as side slope landslide can be prevented.

Description

technical field [0001] The invention relates to the technical field of greening concrete slope protection, in particular to a cast-in-place greening concrete slope protection for inland waterways. Background technique [0002] The traditional slope protection forms of inland waterways mainly include rubble rubble, cast-in-place concrete, interlocking bricks, ecological cages, etc. The existing slope protection methods have poor structural stability and low ecological landscape benefits, and have a great impact on the slope soil and surrounding environment. , is not conducive to ecological sustainable development. In addition, due to wave erosion and water infiltration, the commonly used prefabricated component slope protection is prone to collapse, piping and other damages, increasing maintenance costs. In addition, the measures of laying textile materials such as geotextiles on the slope to maintain soil and water have many durability problems, the service life is short, a...

Problems solved by technology

[0002] The traditional slope protection forms of inland waterways mainly include masonry rubble, cast-in-place concrete, interlocking bricks, ecological cages, etc. The existing slope protection methods have poor structural stability and low ecological landscape benefits, which have a great impact on the slope soil and surrounding environment , is not conducive to ecological sustainable development

Moreover, due to wave erosion and water infiltration, commonly used prefabricated component forms of slope protection are prone to collapse, piping and other damage, increasing maintenance costs

In addition, laying textile materials such as geotextiles on the slope to maintain water and soil has many durability problems, the service life is short, and there is no long-term consideration

[0003] At present, there are many studies on cast-in-place greening concrete, such as CN106759389A discloses a construction method of cast-in-place greening concrete, which is beneficial to plant growth by opening vegetation holes on the surface, but it does not have different slopes and soil types in the slope environment. , pouring thickness and surface hole parameters (ie hole depth, hole diameter, hole spacing) design research, only proposed a surface hole technology, did not specify the parameters of specific applicable scenarios
