Nowadays, land resources in most cities are very scarce, especially in large cities, where housing prices remain high. It can be seen that there are land resources. Now with the opening of the three-child policy to compensate for the aging of the population, the population must be more Now there are more. For those cities with more people and less land, how should land resources be managed? So the land can be filled with high-rise buildings, and the bottom is also very exciting, many underground shopping malls, underground parking lots, and even underground tunnels, etc., because in this way, the use of land resources can be maximized.

Therefore, in order not to occupy more public road resources in many big cities, many railways are being constructed underground. A city forms two passages between the upper and lower sides. The main road above is the fast-moving main road and the subway trains below are high-speed. The utilization rate of land resources is higher, and for transportation, this is another transportation tool. In fact, there are many such cases, like highway tunnels, underground parking garages, etc., but the difficulty of underground construction is definitely It is more difficult than the elevated one, so how do we fix it? Unexpectedly, the excavator long fronts boom can also be used in this way.

Because all aspects of underground exploration are required, we need to use the strength of the excavator long fronts boom. In addition to the conventional excavation, it can also help with the cement pouring, because its effective length can well complete the arched foundation. , The current excavator long fronts boom is not like an ordinary excavator, so it has many more functions. In the infrastructure projects of various countries, there are still many cases of using the excavator long fronts boom. For it, the construction machinery industry is also the same as before love.
