Embodiment 1

[0028] Processing of rockery:

[0029] (1) Mold making: the mold includes an outer mold and an inner mold, and the mold is made according to the established rockery structure;

[0030] (2) Construction waste crushing: the construction waste is made into a powder with a particle size of less than 2mm after coarse crushing and fine crushing;

[0031] (3) Mixing: add the above-mentioned 137kg waste concrete construction waste, 24kg polycaprolactone, 38kg Portland cement, 12kg nano-calcium carbonate, 2kg naphthalene-based water reducer, and 3kg aluminate coupling agent to the mixture in proportion machine, and add water to adjust the solid content of the resulting mixture to 70%, mix evenly, and obtain the rockery processing material;

[0032] (4) Pouring: import the above-mentioned materials into the mold, insert the vibrating rod into the mold, vibrate and tamp the material, and replenish the material until the material is tamped and flush with the opening of the mold;

[0033...

Embodiment 2

[0037] The difference between embodiment 2 and embodiment 1 is the change of raw material consumption.

[0038] Processing of rockery:

[0039] (1) Mold making: the mold includes an outer mold and an inner mold, and the mold is made according to the established rockery structure;

[0040] (2) Construction waste crushing: the construction waste is made into a powder with a particle size of less than 2mm after coarse crushing and fine crushing;

[0041] (3) Mixing: add the above-mentioned 132kg waste concrete construction waste, 21kg polycaprolactone, 36kg Portland cement, 10kg nano-calcium carbonate, 2kg naphthalene-based water reducer, and 2kg aluminate coupling agent to the mixture in proportion machine, and add water to adjust the solid content of the resulting mixture to 70%, mix evenly, and obtain the rockery processing material;

[0042] (4) Pouring: import the above-mentioned materials into the mold, insert the vibrating rod into the mold, vibrate and tamp the material...

Embodiment 3

[0047] With embodiment 1 as contrast, the embodiment 3 that replaces nano-calcium carbonate with equal amount of nanometer talcum powder is set, and all the other processing operations are exactly the same as embodiment 1.

Abstract

The invention discloses a method for preparing a garden rockery by utilizing construction waste regeneration, which relates to the technical field of rockery processing, and comprises the following steps: (1) manufacturing a mold, (2) crushing construction waste, (3) mixing materials, (4) carrying out pouring, (5) carrying out structural densification treatment, (6) carrying out demolding, and (7)carrying out modifying. According to the invention, the construction waste is used as a main material, and auxiliary materials such as polycaprolactone and the like are used for processing to preparethe rockery, so that the reasonable reutilization of the construction waste is realized, and the manufactured rockery is good in appearance quality, high in environmental protection property, good incompression resistance and high in water-retaining property, and facilitates cultivation of green plants on the rockery, so that the environment is beautified and purified.

Description

Technical field: [0001] The invention relates to the technical field of rockery processing, in particular to a method for preparing garden rockery by recycling construction waste. Background technique: [0002] Rockery is a mountain built with soil, stone and other materials for the purpose of landscaping in the garden. Rockery has various landscaping functions, such as forming the main landscape or terrain skeleton of the garden, dividing and organizing the garden space, arranging courtyards, revetments, slope protection, soil retaining, and setting up natural flower beds. It can also be combined with garden buildings, garden roads, sites and garden plants to form a changing landscape, so as to reduce the artificial atmosphere, add natural interest, and make the garden buildings blend into the landscape environment. Therefore, rockery has become one of the characteristics of Chinese natural landscape gardens. [0003] The development of modern garden rockery is different ...
