Description

Technical Field

[0001] The present invention belongs to the technical field of building construction engineering, and in particular relates to a three-dimensional ecological structure system of a residential quarter and a construction method thereof. Background Art

[0002] With the continuous development of urbanization and the continuous improvement of people's requirements for living environment, the ecological livability of residential communities has gradually become an important consideration in purchasing a house; new residential buildings are gradually developing towards a three-dimensional garden ecological residential structure system. This type of residence adopts the design concept of a three-dimensional sky garden, and greening design is carried out on the roof, balcony and public areas of the community to build a multi-dimensional ecological green home.

[0003] Although three-dimensional ecological housing has emerged, its number is small and it is still in the trial and promotion stage. Experience in design and construction is immature, and some designs have been found to be unscientific during use, resulting in occasional problems. For example, residential greening ecological design is mainly based on individual buildings, and a systematic design has not yet been carried out for all buildings and ground in the entire community, resulting in poor greening effects. Waterproof structures such as roof balconies are still designed based on traditional planted roofs. The green areas such as roofs and balconies have insufficient drainage capacity, which makes it easy for planting soil to be lost in extreme rainstorms, thereby contaminating walls and indoor floors. At the same time, the washed soil easily clogs the drainage system. Green areas such as roofs and balconies have difficulty in achieving water retention and growth. The water content of the planting soil is low under the scorching sun, and plants lack water for survival, resulting in low survival rates. Summary of the Invention

[0019] The present invention also provides a construction method for the three-dimensional ecological structure system of a residential area, comprising the following steps:

[0020] Step S1: Complete the water storage tank and drainage tank according to the design drawings, and pre-assemble the elbow pipe and plate filter and install them in the designated position;

[0021] Step S2: mixing high-calcium fly ash-based foamed geopolymer lightweight concrete according to the required mix ratio, and paving a first high-calcium fly ash-based foamed geopolymer lightweight concrete structure layer, a second high-calcium fly ash-based foamed geopolymer lightweight concrete structure layer, and a third high-calcium fly ash-based foamed geopolymer lightweight concrete structure layer of designed thickness on the roof, balcony, and basement top plate, respectively;

[0022] Step S3: Prioritize the application of the roof greening system by preparing a W-OH solution with a concentration of 10% to 12% to form a first W-OH water-insulating buffer layer. When preparing the W-OH solution, control the water temperature between 2°C and 5°C to ensure that the W-OH solution does not set quickly.

[0023] Step S4: construct the balcony greening structure layer by layer according to the design requirements, and simultaneously install the connecting vertical pipes to construct the facade drainage connection structure;

[0024] Step S5, construct ground greening and drainage structure, first complete the construction of sedimentation tank and buried drainage ditch at the designated location, then construct the third high-calcium fly ash-based foamed geopolymer lightweight concrete structure layer (43), and prepare a 10%~12% concentration of W-OH solution to apply the third W-OH water-proof buffer layer, after the third W-OH water-proof buffer layer is formed, the third coarse sand water storage layer and planting soil are immediately constructed, and the sidewalk slabs are simultaneously laid; when laying the planting soil, ensure that the structure meets the design requirements.

[0025] The beneficial effects of the embodiments of the present invention are:

[0026] (1) Three-dimensional ecological structure and systematic drainage structure: The three-dimensional design of roofs, balconies and ground greening effectively improves the integrity and mutual correlation of the ecological structure. The systematic design of roofs, balconies and ground drainage structures can fully utilize and quickly collect and drain rainwater, thereby improving the ecological greening effect of the community.

[0027] (2) Spraying low-concentration W-OH on the surface has the effects of impact resistance, erosion resistance and water retention: low-concentration W-OH (modified hydrophilic polyurethane) is used to spray the surface of lightweight planting soil in the roof greening system and balcony greening system. As an impact-resistant, erosion-resistant and water-retaining layer on the surface of the planting soil, it can prevent the lightweight planting soil from being impacted by rainwater and becoming compacted. While ensuring the normal growth of plants, it can also improve the anti-erosion ability of the planting soil and prevent the planting soil from being washed and splashed by rainwater. The washed soil is easy to settle and block the drainage system, and the splashed soil is easy to pollute the wall. At the same time, the roof is equipped with a three-dimensional storage and drainage system, which can effectively store the collected rainwater and is not easy to volatilize. The excess rainwater is introduced into the connecting vertical pipe through the drainage system. The rainwater collection and discharge system in the roof and balcony greening system can play the role of rapid collection and discharge, preventing rainwater from gathering and seeping into the interior and exterior walls.

[0028] (3) The combined application of new materials can reduce the weight of the structure and optimize the use effect: the use of high-calcium fly ash-based foamed geopolymer lightweight concrete combined with W-OH water-insulating buffer layer can effectively reduce the weight of concrete, and the setting of W-OH water-insulating buffer layer reduces the thickness of the concrete layer. The W-OH water-insulating buffer layer is a flexible gel that can adapt to the temperature stress caused by the volume change of concrete material due to temperature changes between day and night, winter and summer. At the same time, the W-OH water-insulating buffer layer is made of high-concentration W-OH solution and is constructed using a spraying process. It can easily carry out waterproofing work on roofs, balconies and basement roofs. The W-OH water-insulating buffer layer has a significant anti-seepage effect and can improve the frost resistance of roof concrete.

[0029] (4) By setting up an energy dissipation ring, the impact of water hammer can be effectively prevented: by optimizing the design of the bent joint pipe and adding an energy dissipation ring structure, the impact of high-drop water flow on the roof on the pipe body can be effectively avoided, resulting in reduced pipe life and pipe breakage, effectively extending the service life of the drainage riser.

[0030] (5) Spraying special coatings to enhance the pipe's hydrophobic and anti-fouling capabilities: By spraying heat-resistant hydrophobic and anti-fouling coatings on the inner walls of the bend pipes and vertical pipes in the vertical drainage connection structure, the pipe surface can have a super hydrophobic and anti-fouling capability similar to that of a lotus leaf, preventing silt from adhering to the inner wall of the pipe. This can effectively prevent calcification and silt from adhering to the pipe wall during long-term drainage, causing the pipe body to increase in weight, reduce the inner diameter of the pipe, and reduce the drainage capacity. In addition, the heat-resistant hydrophobic material can remain active in the high temperature environment in summer, which can further expand the scope of use of the pipe.

[0031] (6) The ground adopts a wavy planting soil structure, which is conducive to the growth of large green seedlings: The ground greening system adopts a wavy planting soil structure to increase the greening area. At the same time, trees and shrubs can be planted at the crest of the ground wave, which can provide more nutrients and water. Herbaceous plants are planted at the trough of the wave. At the same time, the trough can be used as a deposition area for fallen leaves of trees and shrubs, which is convenient for cleaning leaves. BRIEF DESCRIPTION OF THE DRAWINGS
