Compared with the traditional cast-in-situ shear wall structure, it is mainly reflected in that the peripheral shear wall, infilled wall, air-conditioning board and staircase are precast in the factory, assembled on site, poured concrete or grouted after pouring, Combine them to form an integral structure with good stress; The vertical connection of the stressed shear wall adopts the sleeve grouting method, the connecting reinforcement is inserted into the sleeve, and the high-strength grouting material is poured in the middle to achieve the effective connection of the reinforcement.

The water treatment of the project has the following working modes: the initial runoff and rainwater with heavy pollution are discharged.

After the later runoff and rainwater are collected, the water treatment processes such as “flocculant → integrated rainwater processor → dosing disinfection” are adopted.

The project collects rainwater from the roof, green space and roads of the community.

Advantages and disadvantages of precast integral system (cast-in-situ concealed column and precast wallboard): shear wall structure system is conducive to rational spatial distribution; High prefabrication rate; Compared with PCF system, it has high efficiency and low construction difficulty.

The roof rainwater is collected by the rainwater bucket and discharged to the outdoor building apron or rainwater open ditch through the rainwater pipeline, and then collected by the rainwater inlet and discharged to the outdoor rainwater treatment system for treatment and reuse.

04 Vanke green project planning characteristic light environment 4.1.4 the residential building layout ensures the requirements of indoor and outdoor sunshine environment, daylighting and ventilation, and meets the requirements of the sunshine standard of residential buildings in the current national standard code for planning and design of urban residential areas (GB50180).

When there are 4 or more living spaces, at least 2 living spaces meet the requirements of sunshine standard.

It is a new connection method, and the sleeve and high-strength grouting material are new materials.

According to the calculation, for the project with PC structure, compared with the cast-in-situ structure, the consumables per 100 square meters of construction area are 437kg less steel, 0.35m3 less wood, 600kg less cement and 1420kg less water.

Rainwater collection plan the rainwater collection of this project directly uses the rainwater pipeline in the community to collect rainwater.

The annual rainwater collected in the community is 15343.55m3/a.

Today’s share is: Vanke three-star green precast building technology Vanke precast building 01 Vanke green project overview Vanke Dijie international block B project is located in Beicai Town, Pudong New Area, with Yuqing road in the East and Yuqiao road in the south.

Technical measures for high energy saving rate design ① the filler wall is designed with sand aerated block, with excellent thermal performance ② the outer window is made of plastic steel Low-E hollow glass, and the heat transfer coefficient and shading coefficient are much better than the conventional design ③ polystyrene board internal insulation, thermal bridge strengthening treatment ④ fine decoration, floor slab, partition wall and air conditioning efficiency are higher than the standard requirements ⑤ good building orientation and small window wall ratio, All directions are below 0.4.

Moreover, the precast house has the advantages of good seismic performance, fast construction speed, small occupied area, beautiful appearance and so on.

Among them, the integrated rainwater processor integrates micro treatment units such as sedimentation and filtration, and the treated rainwater is connected to the outdoor water pipe network.

After calculation, the annual energy consumption of buildings 7 ~ 14 in Shanghai Vanke Dijie international city is lower than 80% of the annual energy consumption of reference buildings, meeting the “4.2.10 heating and / or air conditioning energy consumption shall not be higher than 80% of the value specified in the national and local building energy efficiency standards” in the evaluation standard for green buildings (GB / t50378-2006).

Representative project: Dijie B phase II 7#-14# this project is designed for assembled integral residence (PC structure).

02 Project Green compliance green building design logo self-assessment results (three-star residential construction) 03 Vanke green building technology highlights 1 Performance comparison between assembled integral residence (PC structure) PC residence and traditional residence: the development process of industrialization of Shanghai Vanke Vanke industrialization technology system Shanghai Vanke considers the characteristics of the project and the needs of technological innovation.

The rainwater collection area is 33524.98m2.

After many discussions and selection, it does not use the skilled internal pouring external hanging system and PCF system to explore a new precast shear wall system.

The outer wall of the rainwater reuse pipeline is light green; Automatic control device shall be adopted for the treatment system and water supply system of rainwater reuse treatment pump house, and manual control shall be set at the same time; The water quality of rainwater reuse shall meet the provisions of the water quality standard for urban miscellaneous water (GB / T18920-2002).

The project is located in Shanghai and belongs to the climate zone of hot summer and cold winter.

Energy conservation and environmental protection through the use of new materials and new connection technology, the assembly of integral housing improves the construction quality, greatly reduces the energy consumption in the construction process, and has obvious effects of water saving, reducing construction waste and dust suppression.

After treatment, the collected rainwater is used for greening irrigation, site flushing and garage flushing.

Wheel Spacer

There are 8 buildings participating in this evaluation, which are composed of sub items such as buildings 7 ~ 14 in phase II and underground garage.

The rainwater utilization is 10878.5m3/a, and the utilization rate of non-traditional water source reaches 10.19%.

4.5.1 at least one living space in each house meets the requirements of sunshine standard.

Rainwater from outdoor sites and roads is collected by rainwater inlets or open ditches.

The annual rainfall is 1248.7mm for non-traditional water sources in Shanghai.

Acoustic environment the project implements the class II standard in gb3096-2008 acoustic environment quality standard, and the surrounding monitoring points meet the requirements..
