[0033] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] The present invention belongs to the field of green building engineering construction, especially a method of dust control during the construction phase combined with closed precipitation, and the design of water collection and recycling facilities is used in the project operation and maintenance phase to achieve non-disposable use of resource equipment, which can become fixed equipment after the project is completed.

[0035] according to Figure 2Schematic diagram of the effect of the integrated system for recycling and utilizing grey water during the construction and use phases of the gymnasium. During the construction phase, the underground continuous wall groundwater sealing measures and the open ditch plus water collection well dewatering method are adopted for the water stop curtain. The grey water recovered by the 12-water stop curtain flows to the 6-water collection well through the 8-drainage ditch and enters the water recycling and utilization integrated system. The water recycling and water treatment system of the gymnasium construction site includes 7-water recovery module, 5-sedimentation module, 4-depth module and 3-water reuse (reservoir) module. Among them, the 7-water recovery module is connected to the 6-water collection well to collect the grey water discharged by the water stop curtain. The grey water flowing into 6-is first filtered out by preliminary filtration of larger waste residues and wastes, and then flows into the 5-sedimentation module for the next purification treatment. The other end is connected to the 14-wastewater output end and flows into the municipal pipe network. After preliminary treatment, the water source flowing into the 5-sedimentation module is left to settle in the sedimentation module, and then enters the 4-depth module. After the activated carbon adsorbs the suspended matter in the water, it becomes a usable clean water source, and flows through the pipeline to the 3-recovery water reuse (water tank) module for storage and use according to on-site needs.

[0036] At the same time, during the construction phase, rainwater can also enter the system for purification and recycling. The recycled rainwater passes through the 9-rainwater recycling pipeline and directly enters the 5-sedimentation module. After sedimentation, it undergoes the same treatment steps as the recycled water recycled by the water-stop curtain. The above is the process of recycling recycled water, purifying it into usable clean water and storing it.

[0037] The purified clean water is stored in 3-reservoir. The clean water utilization path in the construction stage is ① through 10-recycled water utilization pipeline in the construction stage, where the rainwater is purified and passed through the pipeline design, and the recycled water can be directly used for flushing toilets, washing cars at the construction site, and sprinkling water on site to control dust. The water that has been treated or meets the water quality requirements can be used for greening, structural maintenance water, and concrete test block maintenance water, etc. Utilization path ② through 13-fire water pipeline, it can be used for fire water in the construction stage.

[0038] The construction site water treatment system, rainwater recycling pipeline and fire water pipeline in the construction phase can be directly applied to the project operation and maintenance phase. Clean water utilization methods in the operation and maintenance phase ① The precipitation of the water collection well of the water-stop curtain in the original construction phase can be transformed into 15-spray nozzles, and used for the maintenance of the lawn and green plants in the gymnasium through the 11-water utilization pipeline in the operation and maintenance phase. Clean water utilization method ② Through the 13-fire water pipeline, it can be used for fire water in the operation and maintenance phase.

[0039] The innovations of this invention are: ① Integration of groundwater and rainwater recovery and utilization during the construction phase; ② Recovery and purification equipment and some pipelines during the construction phase can be used for rainwater recovery and utilization during the project operation and maintenance phase; ③ Use BIM technology to display the results of the recovery system, clearly showing the direction of the pipeline, the three-dimensional effect of the integrated system, and the direction of the water flow.

[0040] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
