A kind of potassium magnesium phosphate cement-based ecological retaining wall block and preparation method thereof

Abstract

The invention relates to the field of ecological retaining wall blocks, in particular to a potassium phosphate magnesium cement-based ecological retaining wall block and preparation method therefor. The block is provided with a block shell, a high water absorbent resin particle material bag, an arid plant, a plant soil, and a potassium phosphate magnesium cement-based ceramsite permeable concretefilling material. The block shell comprises a water storage bin, a vegetation bin, communication holes, a partition plate, a bottom rib plate, an anchoring hole, and connecting steel wires. The blockshell is cast from potassium phosphate magnesium cement-based fiber mortars, and pre-embeds connecting steel wires. The bottom rib plate, the communication holes, and the partition plates are designedby a mold when the block shell is cast, and the blocks are connected together by anchoring rods and connecting steel wires. According to the potassium phosphate magnesium cement-based ecological retaining wall block and the preparation method therefor, the weight of the block is greatly reduced with the filling material and the high water absorbent resin particle material bag by arranging the water storage bin and the vegetation bin, the water storage and sewage filtering effects of the block are improved, and the block has the characteristics of water storage, sewage filtering, plant growth,soil blocking, convenience in transportation and installation and the like.

Description

technical field [0001] The invention relates to an ecological retaining wall block, in particular to a potassium magnesium phosphate cement-based ecological retaining wall block and a preparation method thereof. Background technique [0002] The ecological retaining wall is a kind of retaining wall that can not only play the role of ecological protection, but also have the function of landscape, and can prevent soil erosion. Ecological retaining walls have broad market development prospects and can be fully applied in urban river improvement. Ecological retaining walls have become the focus of research in recent years, such as Chinese patent application number 2014800225501, Chinese patent application number 2010105995696, Chinese patent application number 2017100835616, Chinese patent application number 2015107739574, and Chinese Various retaining wall blocks are disclosed in the patent, but these retaining wall blocks all have problems in varying degrees. The block struc...

Problems solved by technology

Although gravel resources are not as severe as river sand, they are also non-renewable resources.

In addition, the hydration of cement in ordinary concrete produces a large amount of Ca(OH)2, which is easy to dissolve in a humid environment, affecting plant growth, and the dissolved Ca(OH)2 adheres to the concrete surface, affecting the effect of landscape decoration

In short, ordinary concrete has the disadvantages of large consumption of natural resources, long production cycle, and poor ecological function.

[0004] Municipal solid waste incineration will produce 20% to 30% of fly ash, ash and other residues, which are currently mainly disposed of through landfill, which is likely to cause secondary pollution
