Let's talk about the intelligent construction of pavement engineering today!

Intelligent, unmanned, and digital are the mainstream improvement directions of the global manufacturing industry1978Japan has developed the world's first intelligent construction robot since then40After years of development, the research and development technology of foreign intelligent equipment has become more and more mature.

The more typical intelligent building equipment can be divided into two categories: road and bridge construction equipment and housing construction equipment. In terms of road and bridge construction, intelligent equipment is mainly divided into compaction, paving, excavation and testing equipment.

The domestic pavement engineering construction field is more in terms of intelligent detection, including compaction detection, intelligent flatness detection, etc., and then feedback to the construction party to adjust the construction process through the detection results, but it has been silent for many years in intelligent construction.

Nearly two years have benefited from the state's pairs“Made in China"The turnThe requirements of upgrading and the focus on research and vigorous promotion of major domestic machinery manufacturers, the intelligent, digital and unmanned construction of domestic pavement engineering has promoted the rapid progress of the work.

The status quo in the field of intelligent pavement construction in China

The domestic research on the intelligent construction of pavement engineering is still in the experimental stage, and has not yet been put into large-scale production. Major machinery manufacturing companies and supporting industrial chain suppliers have invested in higher R & D costs, some of the stronger pavement construction units are also full of expectations for intelligent construction, supply and demand both sides of the joint force, intelligent pavement construction field research is in the ascendant, in general, the reasons for the transformation of domestic pavement intelligent construction are mainly the following aspects:

01workercapitalsourcestrictInsufficient weight

The traditional pavement construction industry is a typical manpower-intensive industry, and with the acceleration of urbanization across the country, the construction market has received a lot of policy support.

self1998Since the country opened up the real estate market, the entire construction industry has continued to a full extent20years of rapid development-During the expansion period, it was just consumed1950-1980this30years of the country“baby boom”The demographic dividend generated. But with1980With the decline in the number of births and the improvement of living standards, more and more workers have begun to flee the hard work of the construction industry.

At present, the most troublesome problem of various construction enterprises is the shortage of workers, and a common phenomenon is that the main labor force on the construction site in the country is more40-60The middle-aged and elderly, the young strong labor force is very little, and in recent years, this phenomenon has intensified, as a small volume, low output value but large demand for workers in the road construction industry, there is a huge gap in worker resources, which has led to the strong demand for intelligent, unmanned construction of various road construction enterprises.

02Overtaking in corners of traditional manufacturing

The development of construction machinery manufacturing industry is carried out simultaneously with the growth of the construction market, represented by a number of excellent domestic construction machinery manufacturing companies such as Sany, XCMG, Zoomlion, etc., which have made great progress in the past ten years, among which Sany Group is settled in the world's top 500 enterprises, representing China's top construction machinery manufacturing level.

But at the same time, it is necessary to deeply realize that the general level of the domestic machinery manufacturing industry is lower than that of Germany, the United States, Japan and other old industrial powers200Years of industrial accumulation, all kinds of technical personnel, manufacturing experience have reached a very high level, in a short period of time to achieve overnight transcendence is very difficult; On the other hand, it is subject to the constraints of the demand-side market of the construction industry, which mostly relies on experience and the improvement of traditional processes, and the demand for new machinery and new methods is not strong.

This leads to the domestic machinery manufacturing industry is more focused on the imitation and transformation of similar foreign countries, although it can compete for the market through cost performance, but it is also easy to be suppressed by the technology of foreign enterprises, domestic machinery manufacturing companies want to achieve corner overtaking at the technical level, unmanned, intelligent mechanical construction is the most suitable racing track.

On the one hand, pavement engineering is already a sunset industry in developed countries in Europe and the United States, and the other party's R&D investment is insufficient. On the other hand, the domestic demand for labor caused by the shortage of labor provides a good stage for the research of unmanned and intelligent machinery. Therefore, many domestic machinery manufacturing companies are gearing up, hoping to complete their efforts and reach the international leading level in one fell swoop through the track of unmanned construction.

Intelligent construction of domestic pavementcollarOutlook for domains

Made in China2025It is a national action plan for the implementation of a manufacturing power, which is clear“Made in China”To to“Made in China”In the transformation, it is necessary to actively promote the technological transformation and upgrading of traditional industries and improve the added value of science and technology in the manufacturing industry. Therefore, the introduction of intelligent means in the traditional construction industry is in line with the requirements of the national environment, and its prospects are very impressive.

For the intelligent construction of pavement, the future development direction will be reflected in the following specific aspects:

  The first is to establish a complete set of unmanned products and digital construction systems.That is, through the combination of the cloud platform and complete sets of unmanned equipment, the whole process of unmanned processing, unmanned transportation, unmanned amortization construction, and unmanned acceptance is realized
