Housing construction technology, the maximum reflects the embodiment of housing construction quality and using function, such as the stability of the foundation and the safety degree of the main structure, within the housing ventilation and lighting structure reasonable degree. With the gradual refinement of the housing construction project, the construction project management is also becoming more complex. Therefore, in the construction of housing construction, the need for continuous accumulation of experience, the construction of housing construction technology for the adaptability of innovation.
Analysis on the construction technology of 1 building construction
1.1 basic construction technology in building construction
In the construction of housing construction, the basic technology including pile foundation technology, two kinds of deep foundation pit technology. For pile foundation technology, with the continuous development of society, the cause of housing rising, the pile foundation technology is in the continuous improvement, now pile foundation technology application scope widely, on the soil is low, able to withstand greater gravity. Moreover, the external demand is also very little. In recent years, the application of concrete filling pile technology is more extensive, this technology is a new technology in the pile foundation. The implementation of this technology not only reduces the volume of the pile, but also can effectively reduce the cost.
1.2 concrete engineering construction technical requirements
Because of the current housing construction, concrete casting has been widely but the pouring method. Therefore, to measure the level of a country's housing construction, the level of development of the concrete industry is one of the criteria for testing. With the use of concrete technology in our country, the new technology of concrete is also constantly pushed out. But in the process of concrete application, we must solve the alkali aggregate reaction, in the construction process, as far as possible the use of high standard expansion agent, water reducing agent, as well as salt and control of sand and gravel content and gradation. In the process of concrete, the first choice of low basic water-based materials should be selected. National Research in this area is constantly expanding, research and development of a high strength and high performance concrete, in order to facilitate the construction process in the selection of more quality materials. Technology of prestressed concrete is also constantly improving, this kind of construction technology not only can reduce the thickness of the floor, the height of the building itself is reduced, but also can reduce the weight of the building.
In view of the concrete construction quality requirements of the guarantee measures, can be divided into the following aspects:
(1) the construction of concrete construction. In the construction process, the configuration of the concrete construction is particularly important, concrete configuration need after calculation of the data of professional and technical personnel, in order to effectively can configure and use, for this step, necessary to have a very meticulous to ensure accurate numerical configuration; (2) pouring concrete construction mechanical device. In construction, according to the concrete construction site using the usage of construction equipment configuration, should have the relevant departments to carry out strict audit and supplies, such as concrete site supplied points, the construction site of the pump truck, backup power supply for construction, concrete construction tanker timely access to the construction site; (3) of concrete on site propulsion. In site concrete way forward, should take the ramp to promote, layered vibrating method, in order to ensure the safety and stability of the future use of concrete, construction safety coefficient is ascended to the highest value; (4) pouring concrete detection. According to the on-site detection of concrete pouring process, it should be using large volume concrete temperature microcomputer automatic test instrument, to facilitate concrete construction and testing the difference in temperature, ensure the concrete normal subsequent play effect, prevent in housing construction, large temperature difference between inside and outside, resulting in building crack problem, the service life of the buildings and the use of functions. Only through the above comprehensive testing methods and operation process, the concrete application in the project performance is complete, for the subsequent use of the guarantee.
2 problems and corrective measures in the housing construction project
2.1 quality treatment of building foundation
For housing construction in the current situation is concerned, not the introduction of relevant quality requirements of the mandatory requirements. In the construction of many buildings, construction workers hands and not to local address detailed investigation report, usually by reference near already existing building design data for the structure design of the building itself and construction, due to the construction design is not rigorous, housing construction to bring great security risks. As far as this problem is concerned, we need to pay attention to the geographical and basic design must be strictly cautious, so reasonable and safe.
The correct approach should be on building the actual land on-site investigation, and according to that survey data, access to relevant geological data, multiple comprehensive factors, in the foundation design of building structure. In many housing construction, the foundation of most of them are based on the experience of their own design, such an approach to the use of housing construction in the future to bury a lot of security risks. Only on the foundation of the soil in depth research can correspond to different construction conditions to take the appropriate measures to save. Anyway, in the foundation needs to be emphasized is according to the local geology and humane conditions, types of building structures, around the type of environment, working conditions, comprehensive analysis and selection the best foundation design.
2.2 housing water seepage treatment
In the building, the water seepage problem is one of the common problems, because in the process of use of housing, the causes of water seepage, there are many, for example, anti seepage material quality specifications lower, the anti seepage construction technology is not complete, the housing internal pipeline maintenance is not timely problems will affect the housing waterproof quality. In the construction process, the integrity of the waterproof project directly determines the water seepage in the use of housing in the case of the possibility of the size of the. Solve the problem of water seepage in the housing construction project, it should be found that the most fundamental reason to make the quality of housing waterproof project to be improved. In order to improve the quality of waterproof housing, in addition to a good design concept, but also need to have excellent material equipment, only in this way can improve the water seepage problems.
2.3 housing wall cracks remedial treatment
The wall cracks are caused by the concrete construction is not in accordance with the standard. It is divided into two parts: the concrete in the process of settlement, plastic subsidence caused by cracks, configuration process of concrete slump spent. In the concrete pouring process, the surface moisture evaporating rapidly, resulting in concrete due to the nature of its own rapid contraction, hydration heat caused by cracks; second, cracks due to temperature stress, factors produced by this kind of reason is because in the concrete pouring process, internal hydration heat is not easy to discharge, resulting in concrete internal temperature rise rapidly, temperature difference between inside and outside are increasing rapidly, resulting in high strength concrete surface, resulting in cracks.
In view of the above situation should be in concrete mixing process is strictly prohibited free water, according to the plastic of the improvement measures, should be in after the completion of the construction of concrete, to give the necessary maintenance, as far as possible to reduce slump, the lower the rate of sand and aggregate in strict control of concrete mixing mud. For temperature caused cracks, should be in the selection of concrete, strictly control the reaction heat of hydration, reduce the heat produced in the concrete pouring process, in this process, should also stop concrete in the reaction process of outside heat absorption. In the process of transportation and storage, it should be possible to carry out the treatment of shading as far as possible, in order to prevent the concrete from warming up under natural conditions. If the problem is caused by the construction should professionals assess and detection, and the construction workers for on-site guidance, prevent a project to appear this kind of problem, and to the project immediately to take remedial measures.
3 conclusion
In the construction of housing construction problems are caused by the small oversight of the construction safety hazards. In the new era of social and economic development, housing construction industry has been steadily advancing, the safety of housing construction projects directly linked to the safety of people living. So, the Department should constantly update a better, more environmentally friendly resources. At the same time, it should on the housing construction related personnel of regular training, and in the construction of, should constantly guide construction personnel in accordance with construction specifications and requirements of the construction work, and resolutely put an end to cut corners in every link, strictly prohibited late safety hazards caused by blind construction, from the fundamental guarantee for the housing security for the country and the people.
