Description

Technical Field

[0001] The invention belongs to the technical field of building construction engineering, and specifically relates to a three-dimensional ecological structure system and a construction method for a residential quarter. 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 areas 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 construct a multi-dimensional ecological green home.

[0003] Although three-dimensional ecological houses have appeared, their number is small and they are still in the trial and promotion stage. The experience in design and construction is not mature yet. Some designs are found to be not scientific enough during use, which leads to some problems from time to time during use. For example, the greening ecological design of residential buildings is mainly carried out in individual buildings, and the systematic design of buildings and ground in the whole community has not been carried out, resulting in poor greening effect; waterproof structures such as roof balconies are still designed with traditional planting roofs as templates, and the drainage capacity of green areas such as roofs and balconies is insufficient. It is easy to lose planting soil in extreme rainstorm environments, thereby polluting walls, indoor floors, etc. At the same time, the washed soil is easy to clog the drainage system; it is difficult to achieve water retention growth in green areas such as roofs and balconies. The water content of planting soil is low under the sun, and plants lack water for survival, resulting in low survival rate. Summary of the invention

[0023] Step S1, complete the water storage tank and drainage tank according to the design drawings, and assemble the elbow pipe and plate filter in advance and install them to the designated position;

[0024] Step S2, mixing high-calcium fly ash-based foamed geopolymer lightweight concrete according to the ratio requirements, and paving the first high-calcium fly ash-based foamed geopolymer lightweight concrete structure layer, the second high-calcium fly ash-based foamed geopolymer lightweight concrete structure layer and the third high-calcium fly ash-based foamed geopolymer lightweight concrete structure layer of designed thickness on the roof, balcony and basement top plate respectively;

[0027] Step S5, constructing 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% to 12% concentration of W-OH solution to apply the third W-OH waterproof buffer layer, and after the third W-OH waterproof buffer layer is formed, the third coarse sand water storage layer and planting soil are carried out immediately, and the sidewalk slabs are laid at the same time; when laying the planting soil, ensure that the structure meets the design requirements.

[0028] The beneficial effects of the embodiments of the present invention are:

[0029] (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.

[0030] (2) Spraying low-concentration W-OH on the surface has the effects of impact resistance, scouring 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, scouring-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-scouring ability of the planting soil and prevent the planting soil from being scoured and splashed by rainwater. The scour 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.

[0031] (3) The combined application of new materials can reduce the deadweight of the structure and optimize the use effect: the use of high-calcium fly ash-based foamed geopolymer lightweight concrete combined with W-OH waterproof buffer layer can effectively reduce the weight of concrete, and the setting of the W-OH waterproof buffer layer reduces the thickness of the concrete layer. The W-OH waterproof buffer layer is a flexible gel that can adapt to the temperature stress caused by the volume change of concrete materials due to the temperature changes between day and night, winter and summer. At the same time, the W-OH waterproof buffer layer is made of high-concentration W-OH solution and is constructed by spraying technology. It can easily carry out waterproofing construction on roofs, balconies and basement tops. The W-OH waterproof buffer layer has a significant anti-seepage effect and can improve the frost resistance of roof concrete.

[0032] (4) By setting up an energy dissipation ring, the impact of water hammer can be effectively prevented: By optimizing the design of the curved joint pipe and adding an energy dissipation ring structure, the high-drop water flow on the roof can be effectively prevented from impacting the pipe body, causing problems such as reduced pipe life and pipe breakage, thereby effectively extending the service life of the drainage riser.

[0033] (5) Spraying special coatings to enhance the pipe's water-repellent and anti-fouling capabilities: By spraying heat-resistant water-repellent and anti-fouling coatings on the inner walls of the curved connecting pipes and connecting vertical pipes in the vertical drainage connection structure, the pipe surface can have super-strong water-repellent and anti-fouling capabilities similar to the surface of lotus leaves, preventing silt from adhering to the inner wall of the pipe. This can effectively prevent the increase in pipe weight, reduction in pipe inner diameter, and decreased drainage capacity caused by calcification and silt adhering to the pipe wall during long-term drainage. In addition, the heat-resistant water-repellent material can remain active in the high temperature environment in summer, which can further expand the scope of use of the pipe.

[0034] (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 crests of the ground, which can provide more nutrients and water. Herbaceous plants are planted in the troughs. At the same time, the troughs can be used as the deposition area of ​​fallen leaves of trees and shrubs, which is convenient for cleaning leaves. BRIEF DESCRIPTION OF THE DRAWINGS
