Current situation and development trend of building construction technology?

The development of construction industry has a great influence on economic development. The level of construction technology is an important index to measure the level of construction industry. In recent years, China's building technology has made great progress in all aspects, and a number of new technologies and new processes have been independently developed in building technology. Here, Zhong Da Consulting Bidding Teacher will answer your questions for your reference.

I. Overview of current construction technology in China 1. It is summarized that China's current construction technology is developing rapidly, which can basically reach the same level as the international construction industry and belongs to relatively advanced construction technology. The following is a brief analysis of several specific construction technologies. (1) Pile foundation technology in building construction technology. Pile foundation is the most widely used form in building construction technology, in which cast-in-place piles are widely used because of their Excellence, while concrete precast piles are seldom used because of their many defects. The main advantage of cast-in-place pile is that it is not limited by soil, and the diameter and length of pile are not limited. At present, there have been cast-in-place piles with a diameter of three meters, a length of 104nl and a bearing capacity exceeding 10,000 kn in the construction industry. In recent years, the main methods suitable for underwater operation are long spiral drilling and pressure grouting, but the diameter and length of piles are limited and cannot be fully reinforced. Mudhole pile is the most widely used pile type in high-rise buildings, which has strong applicability and is combined with other technologies. After improvement, it will be more distinctive, and it will be matched with cast-in-place pile technology in building construction technology. In the aspect of bearing capacity of pile foundation, computer technology is used for accurate dynamic monitoring. (2) Foundation pit supporting system. Foundation pit is an important link in building construction, especially the rapid increase of high-rise buildings in recent years, which makes foundation pit technology more important. High-rise buildings require deep foundation pits, and the foundation pit supporting engineering requires combining factors such as environment, climate, soil and groundwater to achieve waterproof, soil-proof and firm purposes. Therefore, the selection of foundation pit supporting system needs to be extremely cautious, depending on various conditions. In China's construction industry, there are mainly two kinds of foundation pit supporting systems: one is soil nailing wall system, which can reduce the project cost to 40% to 60% of the traditional foundation pit supporting system. This system is mainly suitable for sites with low water level and soft soil. The second is the top-down arch wall system, which excavates in layers like soil nailing wall, and at the same time, the construction cost can be reduced to 50% to 70% of the traditional support system, and more non-soft soil sites are used. In the space support system, the effective control of groundwater has rich experience in China, and the compound method is adopted in China. Generally speaking, the technology of foundation pit support in China is not mature enough and needs more progress and development. 2. The technology of making concrete with new materials. In the construction industry at home and abroad, cement has become the most important structural material in construction engineering, and concrete made of cement has the advantages of high strength and minimum energy consumption, which has been unanimously affirmed by the construction industry at home and abroad. High-strength concrete is widely used in high-rise buildings because of its high strength and high deformation modulus, which can achieve multiple beneficial purposes such as changing the column spacing in buildings, reducing the number of bottom columns in high-rise buildings, unifying specifications, reducing the amount of materials used to make formwork, reducing construction time, ensuring safety and improving the usability of high-rise buildings. 3. Using new materials to improve the technical level of waterproof engineering In recent years, China's independent research and development of new waterproof engineering technologies has made great progress, and some even formed a complete process. The new construction technology mainly includes hot melt method. Through the application of various new materials in waterproof engineering technology, some loopholes and disadvantages of traditional waterproof engineering construction technology are perfected, making waterproof engineering more perfect. The newly developed roof waterproof technology has made obvious progress in the construction technology of waterproof engineering in China. Second, the future development direction of building construction technology in China 1. New materials have many advantages in replacing traditional materials, which can be improved to make up for the shortcomings of traditional building materials, and new building materials can replace some traditional building materials as the main materials in the future development. In the future, it is necessary to conduct more in-depth research on high-performance concrete as a new building material, comprehensively develop all the characteristics and advantages of this material, and apply it to building projects. At the same time, actively and effectively promote new materials in construction projects, reduce traditional materials with high energy consumption and high cost, and improve the utilization rate of building materials and chemical products suitable for construction projects. 2. Comprehensive application of computer technology and building technology Computer technology has changed human beings and society, and the application of computer technology system in the building industry will bring all-round development of the building industry, which is the future development direction of building technology. At present, computer technology is widely used in building engineering, such as the management of various materials and accurate measurement. The application of computer technology has the following multiple benefits: automation, reducing personnel cost and energy; Improve the construction efficiency of building engineering; Accurate specification data to ensure the engineering quality; Connect with the network, realize the goal of modernization, etc. In the future, computer technology will be more widely used in all kinds of management and engineering projects of construction projects, and it will be the mainstream trend to make construction projects meet international standards through the Internet. 3. Constantly improving the industrialization degree of building industrialization requires that the improvement of productivity be accelerated by using advanced equipment and production technology on the premise of advanced technology. To improve building industrialization, it is required to replace traditional technologies and products with advanced, new and efficient technologies and products, improve project quality, reduce energy consumption and pollution, completely replace manual labor, and finally improve the industrialization level of building technology. 4. Improve the productivity of building construction technology with advanced science and technology. In today's society, science and technology are developing with each passing day, and science and technology are the primary productive forces. Building construction technology should catch the train of science and technology, and be good at using the latest scientific and technological achievements to improve building construction technology. The new construction technology is mainly carried out in the following aspects: energy saving and environmental protection technology, consuming a lot of energy and polluting the environment. Through the in-depth study of energy-saving and environmental protection technologies, the purpose of solving energy and reducing pollution is achieved; Underground space technology, underground space can complete the effective use of land and save the construction land area. Improve the application rate of new building technologies, make the latest building technologies be specifically and widely used in the building industry, and make scientific and technological achievements better serve production. To sum up, China's construction technology has made greater and faster progress in recent years, but it has not yet reached the highest international level. The progress and development of building construction technology also require builders to follow the main direction of building construction technology development, improve the level of building science and technology by developing new technologies, new materials and widely applying computer technology, and make unremitting efforts for the development of China's building industry.
