Description

A water-saving building facade greening structure

technical field

The utility model belongs to the technical field of building facade greening, in particular to a water-saving building facade greening structure.

Background technique

With the advancement of urbanization, the increasing building density hinders the direct contact between people and natural plants, which is not conducive to physical and mental health, and at the same time brings a series of problems such as the urban heat island effect. Increasing the green area of plants in buildings is one of the effective ways to solve these problems. Due to the limitations of urban land and the high cost of building space, it is impossible to carry out large-scale plane greening. Therefore, vertical greening on building facades is used to increase the greening rate. , can effectively save land resources and building space. However, there have been many technical problems that have been difficult to break through for a long time, such as structural safety problems, planting construction problems, water supply and drainage problems, maintenance and management difficulties, etc., which have plagued the development of vertical greening on building facades. At present, domestic vertical greening is roughly divided into wall-attached, frame-attached, prefabricated green wall or planting trough, but these forms are not suitable for use on building facades due to factors such as high cost and difficult maintenance and management.

Utility model content

The purpose of the utility model is to provide a water-saving building façade greening structure, which has a reasonable structural design and simple and safe installation and maintenance.

In order to achieve the above object, the utility model adopts the following technical solutions:

The end of each drip irrigation water distribution pipe is connected to a drip irrigation hose with several water outlet holes. The drip irrigation hose is placed in the planting module. On the upper part of the box body, a drip irrigation tank is provided at a position corresponding to the water outlet hole of the drip irrigation hose on the planting module box body.

As an improvement of the above-mentioned greening structure, the main water inlet pipe is sequentially connected with the water pump and the water storage tank, and the water storage tank receives rainwater and household sewage for washing.

detailed description

The preferred mode of the present utility model will be further described in detail below in conjunction with the accompanying drawings.

The utility model mainly uses the combination of the planting module and the frame to realize wall greening. Specifically, each planting module box is fixed on the frame through reasonable lap joints, and the wall greening is drip-irrigated in combination with the collection and reuse of rainwater and sewage. Please refer to Figure 1-3, the vertical height of a single planting module box 9 is controlled between 1000-1200mm, the planting module box 9 is hollow and filled with planting matrix, and the inner diameter and thickness of the planting module box 9 is designed to be 100mm.

Please refer to Fig. 4, each above-mentioned planting module box 9 is provided with planting holes 6 on the outside of the disposal direction, which are convenient for planting. 9 are arranged in a staggered manner, and the distance between the adjacent planting holes 6 is about 15cm. When planting, the plants need to be fixed on the vertical plane with a sponge, so that the stable growth of the plants can be guaranteed, and the loss of the growth substrate can be avoided.

Since the planting module is located on the vertical wall, natural rainwater cannot enter the planting medium, and a supporting water system is required for irrigation. Rainwater and household sewage can be collected for watering green plants on the façade. Therefore, it is necessary to design a water tank or a water storage bucket and a water pump near the water source, and the water pump is connected to the main water inlet pipe 1, and the main water inlet pipe 1 transports rainwater to each planting module through a plurality of drip irrigation water distribution pipes 32, and each drip irrigation water distribution pipe 32 The end is communicated with the drip irrigation hose 31 with some outlet holes, the drip irrigation hose 31 is placed on the top of the planting module casing 9, and the planting module casing 9 is provided with a drip irrigation tank 33 at a position corresponding to the outlet hole of the drip irrigation hose 31.

The drip irrigation hose 31 is generally made of soft PE material, and normally uses a 16mm diameter pipe. Each water outlet hole on the drip irrigation hose 31 can effectively prevent clogging through patch treatment. The drip irrigation pipe does not have high requirements on the performance of the water pump, and the power of 370W and the head of 3000mm can meet the needs. The distance of each water outlet hole is 200mm, and the water output of each hole is 2.5L/h. It is not appropriate to water too much each time. The module has good water retention and requires less water. Drip irrigation can not only be placed on the surface of the substrate, but also can be buried in the substrate without affecting the work. The laying length of a single pipe can reach up to 500m.

Considering the load-bearing structure of the connection between the façade greening module and the wall, the substrate for plant growth cannot directly use pastoral soil. Pastoral soil not only has a high potential risk of pests and diseases, but also has a heavy quality. Long-term planting is prone to soil compaction, which is not conducive to the long-term growth of plants. Therefore, the selected planting nutrient substrate must have important characteristics such as light weight, loose and moderate. The growth substrate is made of peat soil, cinder, and sawdust mixed at a ratio of 1:1:1. This kind of light substrate is not only light in weight, large in water holding capacity, good in ventilation, and conducive to plant growth, but also cheap in price. The density of ordinary soil is about 2.6-2.8t/m ³ , but the density of this kind of substrate is generally only 0.4-0.6t/m ³ , even when the substrate is saturated with water, the density will not exceed 0.8t/m ³ , so this kind of The light matrix will not cause too much impact on the load bearing of the frame.

During construction and installation, the building wall body 8 pre-embeds metal connectors 10 along the vertical direction at intervals of 600-900 mm during the masonry process. The purlins 2 in the vertical direction are welded to the connectors 10, so as to provide a stable foundation for the installation of the planting modules. The planting matrix 5 is filled in the planting module box 9, and the green plants 7 are implanted in the box in sequence, and the gap between the planting holes 6 and the green plants 7 is tightly plugged with a sponge. Then the planting module box 9 with green plants is installed on the purlin 2 through the buckle 4 . The module size and installation density can be adjusted appropriately according to the size of the wall and the type of green plants. Finally, the main water inlet pipe 1 connected to the rain and sewage collection device is arranged along the direction of the purlin 2. One end of the main water inlet pipe 1 is connected to the rainwater and sewage collection tank and the water pump in the equipment room, and the other end is connected to the drip irrigation distribution pipe 32 and the drip irrigation hose in turn. 31. Arrange the drip irrigation hose 31 along the drip irrigation groove 33 at the top of the planting module box 9. Of course, the drip irrigation hose 31 here can also be selected to be directly embedded in the planting matrix 5 .

The above embodiment is only a description of the preferred implementation of the utility model, not to limit the scope of the utility model. Without departing from the design spirit of the utility model, those of ordinary skill in the art made the technical solution of the utility model Various modifications and improvements should fall within the scope of protection determined by the claims of the utility model.
