Concrete cutting refers to the use of tools such as hydraulic wall saws, electric disc saws, rhinestones or road cutters to cut concrete components, walls, pavements and other facilities and equipment made of hard and solid concrete materials, adjust the size, etc. Construction Technology. It has the characteristics of strong cutting ability, non-destructive static force, high efficiency, water cooling, and no construction dust. The concrete cutting machine is composed of six parts: a frame, a turning table, a cross-cutting mechanism, a horizontal cutting car, a hydraulic system and an electric control system.
The frame is composed of left and right longitudinal beams, cross beams, columns, racks, pointed rails, etc. The main function is to make the horizontal cutting car move horizontally on the track and the cross-cutting mechanism to move vertically on the track; the cross-cutting mechanism is composed of It is composed of cross-cutting frame, transmission and spanning device, guide wheel, swing device, cutting wire, etc. The transmission and crossing device drives the cross-cutting frame to cut the blank vertically, and the cutting wire swings in both directions at the same time; the horizontal cutting car is composed of the frame, the scraper device, the edge trimming device, the transmission device, the hanging column, the grooved wheel group, and the Pinglun group. And other composition. Two sets of grooved wheels and two sets of flat wheels are installed on both sides of the horizontal cutting car. The transmission device drives the horizontal cutting car to walk back and forth on the pointed rail and the flat rail to realize horizontal cutting and "breadhead" cutting; the turning table consists of a turning frame, The cart, the trolley, the turning main cylinder and the walking cylinder, etc., whose function is to use the blank placed horizontally on the turning table to flip forward 90° and move to the cutting position for horizontal, vertical cutting and six-sided cutting , After cutting, turn back to the starting position; the hydraulic system is composed of oil station, motor, oil pump, various valves, pipe joints, etc. The main function is to make the turning table turn 90° smoothly and accurately, and the cart and trolley move to the corresponding position synchronously; the electrical control system realizes the manual and automatic control of all actions according to the requirements.
Current Situation Analysis and Prospect Forecast of Concrete Cutting Industry
The concrete cutting machines used in modern society mainly include electric and fuel oil. Electric cutting machines include rechargeable and battery-powered types. Because industrial cutting machines often need to work for a long time, fuel-based cutting machines are more commonly used. The fuel market share reached 75.27% in 2019. In the future, under a series of high requirements for environmental protection and energy saving, electric cutting machines are expected to have an upward trend.
In recent years, concrete cutting technology has developed vigorously with the acceleration of urbanization, and urban construction has been changing with each passing day. For example, in terms of transportation, the ground can no longer meet the traffic demand. Urban traffic extends upwards to elevated and light rails, and downwards to subways. New road planning and construction inevitably require the demolition, reconstruction and reuse of old facilities. Traditional demolition construction methods such as pneumatic pick chiseling and gas cutting or directional blasting often cannot meet some special requirements for construction. In engineering, modern urban life, people pay more attention to safety, efficiency, and environmental protection. Traditional blasting technology will cause serious damage to the main structure of the project, and will cause considerable noise, which will interfere with the normal rest of the residents to a certain extent. Reinforced concrete cutting technology has greatly improved these problems. It basically produces no noise when used, and has higher safety. It can achieve precise cutting, avoid the destructiveness caused by blasting, and truly achieve the goal of scientific demolition and green demolition to a certain extent. This reduces construction costs. After a long period of development in the industry, urban construction is increasingly inseparable from advanced reinforced concrete cutting methods. In 2015, the market value of the concrete cutting industry was 744 million U.S. dollars, and by 2019, it had risen to 875 million U.S. dollars.
Developed countries in Europe and the United States have developed earlier and better in national infrastructure construction. The huge demand for concrete cutting machines in the downstream market stimulates the rapid development of the industry. Europe is the main producer of concrete cutting saws. In 2019, the market share of the concrete cutting industry is as high as 41.61%, the market is in a relatively stable state. The economically backward countries such as the Middle East and Africa are slow in terms of national infrastructure and industrial development. The low demand in the downstream market directly leads to the recession of the concrete cutting industry. As of 2019, the Middle East and Africa region was only 1.43. %, but with the rapid economic development and the acceleration of the process of globalization, there is huge room for development in backward areas. China is the most potential concrete cutting market. With the rapid economic development in recent years, it has become the world's second largest economy. However, China’s per capita disposable income is still only about 1/4 of that of high-income countries, and it still has a relatively high Large room for development, the market share of the concrete cutting industry in 2019 is 19.13%.
The Impact of COVID-19 on the Concrete Cutting Industry
Since the outbreak of COVID-19 in early 2020, the virus has spread all over the world and the spread is extremely wide. The impact of the epidemic in different industries is different. During the epidemic, governments of various countries have introduced a series of measures such as extending holidays and delaying operations to control the flow of people and reduce the occurrence of cross-infection. Many companies cannot carry out normal production and operation. The downstream of the concrete cutting industry, such as the construction industry, was greatly affected by the epidemic, which in turn hit the concrete cutting industry. The market value of the concrete cutting industry in 2020 is 8.75 US dollars, which is a slight drop from the 826 million US dollars in 2019. This is the first time the industry's market value has fallen in recent years. The impact of COVID-19 on the concrete cutting industry is expected to be only temporary. After the epidemic is restored, it will continue to show its development vitality.
