rockery is a mountain constructed with materials such as soil and stone for landscaping in a garden. The rockery has various landscaping functions, such as forming a main scene or a terrain skeleton of a garden, dividing and organizing garden space, arranging courtyards, revetments, slope protection and soil retaining, and arranging a natural flower bed. The landscape architecture can be combined with garden buildings, garden roads, fields and garden plants to form a scene rich in changes, so that artificial atmosphere is reduced, natural interests are added, and the garden buildings are converged into a landscape environment. Therefore, rockery is one of the characteristics of representing the natural landscape garden of china.
The development of modern garden rockery is different from that of garden rockery, and the trend of diversification and synthesis is presented. The classical rockery is limited to stone materials, construction technical conditions and the like, and has certain limitation in the creation aspect of landscape. But the development of modern construction technology and artificial stone materials gradually makes it possible to create changeable and rich mountain and stone landscapes. Especially for the creation of large-scale and large-volume stone mountains, the inspiration of creation can be absorbed from the natural landform morphological characteristics and combination characteristics. The material is cement, mortar, concrete, glass fiber reinforced plastic, organic resin and GRC (glass fiber cement with low alkalinity), so that the plastic stone is formed in modern gardens. The advantages of the plastic stone are that the shape is random and changeable, the size can be large or small, the color can be changed, the weight is light, the stone is saved, the plastic stone works with modern interest are saved, and the plastic stone is especially suitable for places with limited construction conditions or limited bearing conditions.
The construction waste (waste concrete construction waste and brick-concrete construction waste) accounts for the largest proportion of the total amount of various construction wastes, and is the main object of resource treatment and utilization of the construction waste at present. At present, waste concrete construction waste and brick-concrete construction waste are mainly processed into recycled coarse aggregate and recycled fine aggregate, and are used for producing concrete, mortar, concrete bricks and inorganic mixtures in road engineering. At present, the generation amount of construction waste is large, and if the construction waste is unreasonably utilized, the environment is seriously influenced. The processing of the rockery needs various inorganic materials, and in order to realize the application of the construction waste in the rockery processing, the invention provides a rockery processing method taking the construction waste as a main material.
The invention content is as follows:
the invention aims to solve the technical problem of providing a method for preparing a garden rockery by utilizing construction waste regeneration, which not only realizes the regeneration and the utilization of the construction waste, but also ensures that the prepared rockery has strong environmental protection property and good appearance quality and use quality.
The technical problem to be solved by the invention is realized by adopting the following technical scheme:
a method for preparing a garden rockery by utilizing construction waste regeneration comprises the following steps:
(1) manufacturing a mold: the die comprises an outer die and an inner die, and the die is manufactured according to a set rockery structure;
(2) crushing the construction waste: carrying out coarse crushing and fine crushing on the construction waste to prepare powder with the granularity of less than 2 mm;
(3) mixing materials: adding the construction waste powder, polycaprolactone, Portland cement, nano water-absorbing filler, naphthalene water reducer and aluminate coupling agent into a mixer in proportion, adding water to adjust the solid content of the obtained mixture to 60-70%, and uniformly mixing to obtain a rockery processing material;
(4) pouring: introducing the materials into a mold, inserting a vibration rod into the mold, tamping the materials through vibration, and supplementing the materials until the materials are leveled with an opening of the mold after being tamped;
(5) and (3) structural densification treatment: placing the cast mould in a heat treatment chamber, heating to 130-140 ℃ at a heating rate of 5-10 ℃/min, preserving heat until water in the material is volatilized, transferring into a cold treatment chamber, cooling to-5 ℃ at a cooling rate of 5-10 ℃/min, preserving heat, standing for 0.5-2h, and naturally recovering to room temperature;
(6) demolding: separating the outer mold and the inner mold to obtain a rockery crude product;
(7) modification: and (4) performing surface finishing on the produced rockery crude product to obtain a rockery finished product.
The method utilizes the principle of expansion with heat and contraction with cold, and adopts the operation of temperature programming and temperature programming to densify the internal structure of the manufactured rockery, thereby avoiding the occurrence of a gap structure inside the rockery and further enhancing the mechanical properties, particularly the compressive strength, of the manufactured rockery.
The construction waste is selected from one of waste concrete construction waste and waste brick mixed construction waste.
The nano water-absorbing filler is selected from one of nano calcium carbonate and nano talcum powder.
The mass ratio of the construction waste powder, polycaprolactone, Portland cement, nano water-absorbing filler, naphthalene water reducer and aluminate coupling agent is 100-150:10-30:25-50:10-20:1-10:1-10, preferably 120-140:15-25:35-45:10-15:1-5: 1-5.
The polycaprolactone is prepared by ring-opening polymerization of caprolactone under the condition of taking metal organic compound as catalyst and dihydroxy or trihydroxy as initiator, and belongs to polymeric polyester; the mechanical property of the manufactured rockery is improved by adding the polycaprolactone, so that the novel application of the polycaprolactone in the processing of the rockery is realized, and the environment is not polluted because the polycaprolactone has biodegradability.
In order to further improve the water absorption performance of the nano calcium carbonate as the nano water absorption filler and further facilitate the cultivation of green plants in the manufactured rockery, the invention also carries out surface modification on the nano calcium carbonate, and the specific technical scheme is as follows:

The quantity ratio of the nano calcium carbonate to the polyglutamic acid is 10: 0.5-2.
The invention takes polyglutamic acid as a surface modification treatment agent of the nano calcium carbonate, and prepares a novel substance, namely the nano calcium carbonate with the surface coated with the polyglutamic acid through the modification treatment, the substance absorbs water by utilizing the polyglutamic acid coated on the surface after meeting water, and the water begins to permeate into the calcium carbonate when the water absorption of the polyglutamic acid on the surface reaches the maximum, so that the water absorption of the calcium carbonate is greatly improved, meanwhile, the polyglutamic acid coated on the surface also endows the water-locking capacity, the water absorbed in the calcium carbonate under the high-temperature natural environment is prevented from being quickly lost due to evaporation, and the cultivation of plants on rockery is facilitated.
The invention has the beneficial effects that: the rockery is prepared by processing the construction waste serving as the main material and the auxiliary materials such as polycaprolactone and the like, so that the construction waste is reasonably recycled, and the adverse effect on the environment after the construction waste is discarded is avoided; the manufactured rockery has good appearance quality and strong simulation, and presents vivid scenes; the environment-friendly property is strong, and harmful substances cannot be generated to the environment in the using process; meanwhile, the artificial hillock has good compression resistance and strong water retention, and is beneficial to cultivation of green plants on rockery, thereby beautifying and purifying the environment.
