1. 1 Overview of high-rise civil buildings
With the rise of the construction industry in China, high-rise buildings have gradually entered people's field of vision. High-rise buildings not only save urban land resources, but also promote urban economic development. /kloc-high-rise civil construction shall be carried out for buildings with a height of more than 0/0. It is precisely because of the height problem of high-rise buildings that it once brought difficulties to construction. Civil construction technology is a difficult technology, which brings great challenges to high-rise buildings. For example, due to the foundation problems of high-rise buildings in construction, there are certain technical requirements for foundation protection and excavation, and a little carelessness will affect the construction quality. This reflects the importance of civil construction technology, which participates in the whole construction process of high-rise buildings. Therefore, we must carefully choose the civil construction technology and adopt a reasonable scheme to complete an excellent architectural work.
1.2 analysis of construction characteristics of high-rise civil engineering
High-rise civil buildings are construction with higher difficulty coefficient than ordinary buildings, and the construction characteristics are diverse. First, it has the characteristics of high-altitude construction. High-rise building construction, as its name implies, is aerial work. In the process of construction, due to the height of the building, the transportation of materials is also directly vertical transportation with equipment at high altitude. According to various aerial work methods, the fire prevention and the safety of workers during aerial work should also be considered. Second, it has the characteristics of large engineering quantity and large volume.
High-rise building is a huge construction project, which has the characteristics of large engineering quantity. At the same time, due to the intervention of construction personnel, it needs to be constructed according to the design draft, which forms the characteristics of large engineering quantity. Third, it has the characteristics of large foundation depth. Because high-rise buildings are large buildings, the foundation needs to bear more weight than ordinary buildings, so the design foundation depth is greater; Fourth, it has the characteristics of complex and diverse construction conditions. Every building is unique, and it is impossible to refer to the previous building completely. Civil works should be carried out according to the geographical location and related requirements of high-rise buildings. We should not only ensure the quality of the project, but also take corresponding protective measures.
2 disadvantages of current high-rise buildings and civil buildings
2. 1 Foundation construction technology and quality problems.
A building with guaranteed quality has a solid foundation, and the quality of the foundation directly determines the quality of high-rise buildings. Even the highest floor must pay attention to the foundation construction. The higher the floor, the higher the requirement for foundation technology. This is the so-called "economic base determines the superstructure". Of course, the economic base here refers to the foundation. Therefore, when carrying out high-rise buildings, we must attach great importance to foundation construction and lay a solid foundation before starting the subsequent construction.
In the current high-rise building construction, due to the time problem, most of the construction process only pays attention to efficiency. Some construction units only use simple foundation piles for construction, not realizing that unstable foundation will cause accidents, and there is no special treatment for special positions. Under such construction conditions, there has been a serious crisis in high-rise buildings. Therefore, we should attach great importance to the technology and quality of foundation and take various measures to fill the foundation.
2.2 The modeling design of high-rise buildings lacks rationality.
With the development of modern architecture, aesthetics has been fully reflected in architecture. With the development of society, people have a new concept of pursuing beauty and put forward higher requirements for architecture. According to these preconditions, some architects have made new breakthroughs in appearance unilaterally, but their architectural works are not practical. For example, in some architects' architectural works, the lighting of buildings can not meet the requirements of modern life, and there are also some problems in the design of drainage pipes and vents. The adoption of such design drawings will not only affect the daily life of users, but also affect their service life. Therefore, the modeling design of high-rise buildings must be considered reasonably, and the design scheme combining aesthetics with practicality should be adopted.
2.3 construction technology can not meet the requirements of high-rise buildings.
The pace of life is improved with the development of society, and in the process of high-rise building construction, the development and renewal of its technology should also be continuously improved with the development of society. Although it is necessary to pay attention to efficiency in the construction process, it is necessary to consider both efficiency and project quality. Due to the tight construction time, the construction workers reduced the construction procedures, which directly affected the project quality. At the same time, the construction technology of construction personnel will directly affect the quality of the project, so it is necessary to have higher requirements for the construction technology of construction personnel. In other words, we have superb construction technology while ensuring sufficient physical strength. Through the further requirements of construction technology, it laid the foundation for the construction quality of high-rise buildings. Only the construction technology that meets the requirements of high-rise building construction can complete the construction with good quality and quantity.
3 the application of civil building technology in high-rise buildings
3. 1 Application of anti-seepage construction technology
In the construction technology of anti-leakage, it is mainly the anti-leakage of wall, roof and kitchen and bathroom. In the wall anti-leakage construction technology, keeping the wall clean and tidy is the premise of construction. After bricklaying, wall painting is the main way to prevent leakage. When daubing concrete, it is necessary to maintain the uniformity of the whole wall, and choose waterproof building materials to ensure the anti-seepage performance of the wall; The construction technology of roof leakage prevention mainly depends on the secondary painting on the wall coated with concrete. The quality of coating and waterproofing membrane is the main factor that determines the roof leakage prevention.
After selecting high-quality materials, apply them in strict accordance with the construction specifications and carry out construction according to the time requirements, which can protect the roof and prevent roof leakage. In the kitchen and bathroom, it is the easiest to leak water. Therefore, the size of the hole that needs to be reserved must be strictly designed during construction. According to its size, the gap around the hole should be carefully filled with cement to prevent leakage. After the construction is completed, it is necessary to carry out leakage test. If there is leakage, measures should be taken in time to make up for it.
3.2 Application of Foundation Construction Technology
Deep foundation pit supporting technology and bored pile technology are common technologies in foundation construction. According to the social appeal for environmental protection, the use of soil nailing wall in deep foundation pit support technology obviously conforms to the slogan of environmental protection. It has the characteristics of simple construction and low capital consumption, and this technology is gradually accepted by people. In the process of foundation construction, excavator is the main object of earthwork excavation of deep foundation pit, and excavation is carried out in various ways to reduce the influence of space-time effect on retaining wall and prevent its deformation. Cast-in-place pile technology is one of the traditional foundation construction technologies. Its bearing capacity is relatively strong, which can lay a solid foundation for subsequent high-rise buildings.
3.3 the application of concrete engineering construction technology
Concrete engineering is an important project in building construction, which closely links the structure in the building with other structures and ensures the stability of the whole building project. Every construction process of concrete engineering will affect each other. If one of the technical problems is not handled properly, it will directly affect the engineering quality. Therefore, in the construction, it is necessary to ensure the rationality of the structural design of concrete engineering and ensure that the concrete engineering has a fixed processing capacity for its structure. Strictly control the quality of cement and sand, other materials will directly affect the performance of concrete.
