Construction Technology of Shotcrete Machine for Foundation Pit Support

Construction Technology of Shotcrete Machine for Foundation Pit Support

1. foundation pit support shotcrete machine support technology. Engineering technology: slope after slope excavation-dowel, erection of steel frame-suspended steel wire mesh-shotcrete. The length of the steel bar is 14mm, the length is 1500mm @ 1500*1500mm distribution, the depth is 1400mm, and the exposed 100mm. 6 @ 1500mm * 1500mm keel reinforcement. Galvanized steel wire mesh (20*20mm) with 8# steel wire diameter of 2 mm is used vertically and horizontally, sprayed into concrete, and treated by wet method. The diameter of coarse aggregate is 5-10mm, and the surface layer is sprayed twice to ensure the safety of slope. Full.

Wet spray manipulator introduction and manufacturers

Wet spray manipulator introduction and manufacturers

Concrete wet shotcreting machine is the key equipment for concrete shotcrete anchor support construction. Compared with the traditional dry shotcreting machine operation, it can reduce the dust concentration outside the machine edge and nozzle, and effectively reduce the health hazards to workers. Wet spray manipulator is a kind of mechanical equipment for concrete spray support in traffic tunnels, hydraulic tunnels, mine roadways, underground plants, military facilities and other projects. More importantly, the use of concrete wet spray manipulator operation, with a low degree of resilience, can greatly improve the construction efficiency, and because the water cement ratio is easy to control, can greatly improve the quality of shotcrete, reduce labor, effective cost savings.

Selection of Spray Planter for Slope Greening

Selection of Spray Planter for Slope Greening

When many customers first entered the spraying and planting industry, they were faced with the two problems of purchasing the spraying device and selecting the manufacturer. The slope greening spraying machine was originally a niche proprietary machine, so many customers had heard of such equipment. Due to the lack of understanding of the sowing machine, facing the different rhetoric of the salesmen of various manufacturers, I was at a loss for a while. I didn't know who to trust and which manufacturer's products to choose.

Construction Technology of Slope Greening Spraying Machine

Construction Technology of Slope Greening Spraying Machine

The construction of expressways, railways, mines, water conservancy and other projects is often accompanied by a large number of earth and stone excavations. These earth and stone excavations destroy the original vegetation, cause a large number of exposed slopes, cause serious soil erosion and unbalanced ecological environment. The slopes formed in such projects rely on the power of nature itself to restore the ecological balance, which often takes a long time, or even cannot be fully restored. Therefore, the slope must be protected and ecologically protected by the slope greening spraying machine. Greening treatment can prevent slope damage, soil erosion, conserve water, purify air, and beautify the environment.

Construction and Application of Spray Planter

Construction and Application of Spray Planter

According to the soil composition of each area and the requirements of vegetation on the root soil, the spraying machine can supplement the lack of elements and nutrients in the soil to facilitate the growth of vegetation. The thickness of the rooted soil of the three-dimensional drainage and flexible ecological slope project reaches more than 0.3 meters, which fully meets the thickness of the vegetation soil layer required by the local garden standards, and provides a good soil environment for the growth of various herbaceous and woody plants.

Application of slope greening spraying machine

Application of slope greening spraying machine

What is slope greening? 1. slope greening is a new ecological slope protection method, which can effectively protect the exposed slope. Combined with traditional civil engineering slope protection (reinforced anchor, hanging net, grid, etc.), it can effectively restore and protect the ecological vegetation of the slope. 2. slope greening utilization: with the rapid development of economy and society, China's capital construction speed, transportation, water conservancy, mining, power and other construction projects, a large number of exposed slopes have been formed. Slope greening can beautify the environment, save water resources, prevent soil erosion and landslide, and purify the air.

Spray machine to prevent power shortage

Spray machine to prevent power shortage

In the process of operation, when the soil spraying machine is running, it will encounter the situation that the oil inlet distance is not enough due to insufficient power. If the throttle valve of the engine is in a large position and the injection angle is appropriate, it is most likely that the pipeline is not smooth enough, and the lower pipeline can be dredged at this time. In addition, it can also be prevented by the following methods. Today, the sprayer manufacturer will introduce it.

Technical characteristics of foundation pit support shotcrete machine

Technical characteristics of foundation pit support shotcrete machine

Foundation pit support shotcrete machine is the use of compressed air, the concrete mixture according to a certain proportion to a certain proportion of spray to the surface, and a certain speed of spray to the surface, so that the formation of concrete support layer. In recent years, shotcrete technology is widely used in construction, railway tunnels, mine shaft construction, slope reinforcement and other fields because of its simple process, unique construction effect, economic and rapid construction.
