Description

Technical Field

[0001] The invention relates to the technical field of foundation pit slope management, in particular to a foundation pit slope greening structure. Background Art

[0002] The foundation pit is an earth pit excavated at the foundation design location according to the base elevation and foundation plane dimensions. Before excavation, the excavation plan should be determined based on geological and hydrological data and the conditions of nearby buildings on site, and waterproofing and drainage work should be done. For those who excavate deeper or have buildings nearby, the foundation pit wall protection method and the shotcrete wall protection method can be used to prevent the outer soil layer from collapsing. With the improvement of people's environmental awareness and the development of related disciplines (such as restoration ecology and soil and water conservation engineering), people are increasingly aware of the necessity and feasibility of restoring the original vegetation on the slope while carrying out slope protection. The use of organisms (mainly plants) alone or in combination with other structures to protect and green the slope has become a goal pursued by the engineering community.

[0003] The existing slope greening structure is unable to collect rainwater, resulting in the need for manual watering of the plants on the slope, which is time-consuming and labor-intensive, reduces work efficiency, and cannot meet the requirements of use. Therefore, in view of the above situation, there is an urgent need to develop a foundation pit slope greening structure to overcome the shortcomings in current practical applications. Summary of the Invention

[0004] The purpose of the present invention is to provide a foundation pit slope greening structure to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A foundation pit slope greening structure, comprising:

[0007] slope;

[0008] A greening mechanism, the greening mechanism being fixedly connected to the slope and used for planting green plants;

[0009] Water guide troughs are symmetrically arranged on both sides of the greening mechanism and located on the slope to divert rainwater;

[0010] An irrigation mechanism connected to the slope and the water channel for collecting and spraying rainwater;

[0011] Wherein, the irrigation mechanism includes:

[0012] A support box, the support box is fixedly connected and arranged inside the slope;

[0013] A water storage assembly is provided inside the support box and is connected to the water channel for storing and transporting rainwater;

[0014] Spraying components, which are symmetrically arranged on both sides of the greening mechanism and connected to the slope;

[0015] A control assembly is provided inside the support box and is connected to the water storage assembly, and is used to drive the water storage assembly to purify rainwater;

[0016] The transmission assembly is arranged between the control assembly and the spray assembly, and is used to cooperate with the control assembly to drive the spray assembly to achieve rotary watering of green plants.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] When the device is running, green plants are planted on the green plant mechanism. The water guide trough can not only guide the rainwater, but also recycle the excess water in the green plant mechanism. The water enters the inner side of the water storage component along the water guide trough. The water storage component can not only store the rainwater, but also drive the rainwater to flow and purify the rainwater before transportation to avoid clogging of the equipment. The rainwater is sent to the inner side of the spray component and sprayed out from the spray component. On the one hand, the control component can drive the water storage component to realize self-cleaning of the water storage component, and on the other hand, it can drive the spray component through the transmission component to realize rotary spraying, so that the water in the green plant mechanism can be sprayed by the water storage component. The green plants on the slope can be fully watered. Compared with the slope greening structure in the prior art, the present application cannot collect rainwater, resulting in the need for manual watering of the slope plants for subsequent watering, which is time-consuming and labor-intensive, reduces work efficiency, and cannot meet the use requirements. By setting up a watering mechanism and cooperating with the greening mechanism, rainwater can be recycled and the green plants can be watered. The excess water in the watering process can also be recycled, thereby improving the utilization rate of water resources. There is no need for manual water transportation for watering operations, which saves time and labor, improves work efficiency, and meets the use requirements. BRIEF DESCRIPTION OF THE DRAWINGS
