Competition pattern, concentration analysis and development trend of foundation pit support industry
Foundation pit support engineering is one of the indispensable and important projects in geotechnical engineering, which can generally be divided into foundation treatment, pile foundation engineering and foundation pit support. The service face of foundation pit engineering involves almost all geotechnical engineering fields, such as housing construction, transportation, municipal, water conservancy and other engineering fields.
With the rapid development of China's economic construction and the acceleration of urbanization, the available land resources in cities are becoming increasingly tight, and striving for building space at high altitude and underground has become a normalized scene of urban construction. In this context, high-rise, super high-rise buildings and underground space in urban construction in large quantities, more and more deep foundation pit projects, foundation pit support projects are developing in the direction of large depth and large area. Generally, deep and large foundation pits are usually located in the center of dense cities, close to buildings, traffic arteries, subway tunnels and various underground pipelines, etc., the construction site is tight, the construction conditions are complex, and the construction period is tight, resulting in the difficulty of the design and construction of foundation pit enclosure engineering is getting bigger and bigger, and the requirements for environmental protection in the construction process are getting higher and higher, that is, the overall presentation of "large area, deep excavation, tight land, and close to surrounding buildings (structures)" and other characteristics, which put forward new requirements and challenges to foundation pit support technology.
, the development trend of foundation pit support industry
With the increase of building scale and building density in China, the demand for the utilization of underground space is gradually increasing. The design planning and comprehensive construction and construction projects of various large-scale public buildings, residential buildings, urban underground transportation, underground comprehensive pipe corridors and other projects emerge in an endless stream, providing a relatively broad market space for the geotechnical engineering industry and also putting forward higher requirements for foundation pit support; At the same time, with the development of new technologies such as digitalization, informatization, and the Internet of Things, it has also injected new technical impetus into traditional geotechnical engineering construction. Taking science and technology as the support point, building industrialization, informatization and intelligence as the direction, and embarking on a low-carbon economy is the development direction of the geotechnical engineering industry. The future development trend of China's geotechnical engineering industry will reflect the following characteristics:
1) Green buildings bring development opportunities to the industry.
In recent years, the state has paid more and more attention to the development of green buildings, actively promoted the application of new technologies in the field of geotechnical engineering, and promoted the transformation and upgrading of the construction industry in the direction of sustainable development. The "14th Five-Year Plan" for the development of the construction industry continues the orientation of green buildings, emphasizing the establishment of green construction policies, technologies and implementation systems, the implementation of green construction standard systems, and the full implementation of green construction in first-class investment projects and large-scale public buildings.
In the future, the design and construction of geotechnical engineering need to follow the requirements of green buildings and green construction, fully realize energy conservation and emission reduction, and reduce environmental pollution. New energy-saving and environmentally-friendly construction methods will be promoted, such as the SMW construction method with energy-saving and environmental protection characteristics and the reverse construction technology. According to the "Implementation Plan for Carbon Peak in the Building Materials Industry", the foundation pit support process with high carbon emissions will be limited, and the construction method with energy saving and environmental protection characteristics will be favored. As a representative of sustainable development and circular economy green construction method, the TRD construction method has obvious advantages in reducing the cost and can bring more development opportunities to the field of geotechnical engineering.
2) Standardization of construction technology and widespread use of prefabricated buildings.
There are some problems in the development process of the construction industry, such as extensive development mode, low labor productivity, high energy consumption and high emissions, non-standard market order, low overall construction quality, and frequent engineering quality and safety accidents. In order to solve these problems, the "14th Five-Year Plan for the Development of the Construction Industry" proposes a series of measures.
Prefabricated component technology is widely used in developed countries, but there is still a lot of room for promotion in China. Through the research and development and application of standardized construction technology and low-energy consumption and low-emission prefabricated component technology, it can effectively promote energy conservation and emission reduction in the construction industry. Among them, prefabricated buildings are a manifestation of standardized construction technology, and the plan proposes that by 2025, prefabricated buildings will account for more than 30% of new buildings, while controlling the discharge of construction waste, and initially forming a market mechanism for construction waste treatment and reuse.
In the field of foundation pit support, the construction of underground enclosure system in the future will also tend to be prefabricated and standardized. The prefabricated foundation pit support technology has many advantages, such as large overall stiffness, light weight, fast and convenient installation and dismantling, and reusability, which helps to save construction period and cost, and achieve the environmental protection and energy-saving goal of green construction.
3) The penetration rate of intelligent and digital industries has increased.
With the development of the Internet, the application of BIM technology in the construction industry has become increasingly popular, which has promoted the development of the construction industry in the direction of personalization, customization and intensification, and realized the sharing of data and information in the upstream and downstream of the industrial chain. New technologies such as cloud computing, Internet of Things, artificial intelligence, 5G and construction robots are combined with BIM technology to promote the innovation of the construction industry information market. In April 2020, the Ministry of Housing and Urban-Rural Development proposed to promote the BIM drawing review model, which promoted the integrated application of BIM technology in the whole process of engineering construction.
In the future, with the in-depth application of artificial intelligence, big data, cloud computing, and Internet of Things technologies in the construction field, it will promote the modernization, scientific and intelligent management of geotechnical engineering, and improve the level and efficiency of refined management of engineering projects and industries. This will help to implement sustainable development concepts and measures throughout the life cycle of geotechnical engineering, and promote the transformation of geotechnical engineering from "construction" to "intelligent manufacturing".
The concentration of foundation pit support industry has been improved
The geotechnical engineering industry is affected by geological conditions, and there are great differences in the applicable machinery and equipment, construction technology and management methods in different regions. In the early days, there was regional protection in the construction industry, which led to low concentration in the geotechnical engineering industry, small enterprise scale, limited technical level, and competition mainly relying on first-class advantages.
With the progress of science and technology and the development of the market economy, professional enterprises with rich project experience, high technology level and good reputation can expand in different regions, and the industry concentration gradually increases. As the construction conditions of geotechnical engineering become more complex, the building grade is improved, and the requirements for construction efficiency, energy saving, environmental protection and quality are getting higher and higher, and traditional competition methods such as competition are difficult to meet the demand. Technologically advanced, safe, efficient, and environmentally friendly companies will gain more market share.
In the process of expanding the market scale and increasing market share, geotechnical engineering enterprises that cooperate closely with public construction projects, science and technology enterprises and general construction contractors will stand out, enhance their comprehensive strength, and increase industry concentration.
, foundation pit support industry competition pattern
According to the national public service platform for construction market supervision, there are more than 5,000 enterprises with first-class qualification for professional contracting of foundation and foundation engineering, and the market is relatively scattered and the competition is very fierce.
From the perspective of competitive business types, the enterprises currently participating in the competition of foundation pit support engineering mainly include the following three categories:
In terms of scale, there are mainly the following three echelons:
Due to the different geological structures in various places, the difference in the technical requirements of the required foundation and foundation engineering is greater than that of the main ground project, so the foundation and foundation engineering industry is still dominated by regional competition. At present, some regional industry-leading enterprises have been formed in various regional markets, such as Sinochem Geotechnical, Shanghai Foundation Engineering Group, Zhejiang Geology and Mineral Engineering Co., Ltd. and Dongtong Geotechnical, etc., which have strong influence and market share in the region. As a highly specialized subdivision industry and regional radius limitations, most foundation and foundation engineering enterprises lack the strength of cross-regional operation, and only a few enterprises belonging to large state-owned enterprise groups have the ability to conduct business nationwide.
With the strengthening of the planning and supervision of industry technical standards, the trend of breaking down regional barriers in the construction industry under the unified national market, coupled with the continuous improvement of building environmental protection requirements, some enterprises with high technical level, stable service quality, high-quality customer system, core technology and new construction methods, new equipment and new materials research and development and application have more adequate development opportunities, and the geotechnical engineering industry has gradually entered a transition period of industry integration, and the industry concentration will be improved to a certain extent in the future. Customer resources and business opportunities will also be inclined to some enterprises with excellent technology, good reputation, strong research and development, and good service, so that the geotechnical engineering industry will gradually move towards the road of standardization and technological innovation, and finally form a benign competition situation of technical competition and service competition rather than simple competition.
