Description

Technical Field

[0001] The invention relates to a concrete structure slipform construction system, in particular to a concrete structure slipform construction system under high temperature and large temperature difference between positive and negative surfaces, and belongs to the technical field of building construction methods. Background Art

[0002] Slipform construction is the most commonly used method in the construction of concrete structures.

[0003] Slipform construction of concrete structures has been rapidly developed and widely used due to its high degree of mechanization, fast construction speed, small site footprint, guaranteed safe operation, strong integrity of the completed project structure, and good seismic performance. It is an environmentally friendly construction method with significant economic and social benefits.

[0004] The slipform construction system of concrete structure usually includes: lifting system, mold system, operating platform system and auxiliary facilities system.

[0005] Correspondingly, the slipform construction of the concrete structure usually includes: binding of built-in steel bars of the concrete structure, fixing of the slipform construction enclosure and lifting frame in place, making and positioning of internal and external formworks of the concrete structure, installing internal and external operating platforms of the slipform construction, lifting of internal and external formworks of the concrete structure and installation of control devices, pouring of concrete of the concrete structure, lifting of internal and external formworks and removal of internal and external formworks of the concrete structure.

[0006] Slipform construction of concrete structures has its unique advantages. However, since concrete structures constructed using slipforms are often large in size, not only will the concrete itself generate heat and expand during the solidification and strengthening process, but the concrete structure will also be affected by the environment. For example, in hot seasons or hot areas, especially in desert areas with high temperature, little rain and strong sunlight, when slipform construction of concrete structures is carried out, the usual slipform construction method will be severely tested. In those areas, the summer temperature is as high as 50°C or above, and the temperature difference between day and night and the temperature difference between the yin and yang sides can reach dozens of degrees. Slipform construction under such ambient temperatures is very likely to cause quality accidents such as concrete cracking due to high temperature and temperature difference.

[0007] In addition, when slipform construction of concrete structures is carried out in desert areas with strong sunlight, the huge temperature difference between the sunny and shady sides caused by the sun can cause the strength of the concrete on the sunny side to increase too quickly, while the strength of the concrete on the shady side increases slowly. This can lead to the concrete strength increasing asynchronously, causing collapse or cracking during the concrete lifting process. In severe cases, the slipform construction can no longer be carried out.

[0008] In the prior art, there are some special and valuable methods for slipform construction in high temperature and large temperature difference environments, such as:

[0009] The invention patent (application number: CN201010279909.7) disclosed in the "Concrete Silo Slipform Temperature Control Method in High Temperature Environment" includes: a. concrete mix design, setting concrete slump; b. selection of concrete raw materials; c. lowering the temperature during concrete mixing and transportation; d. controlling the supply rhythm of concrete, setting the concrete supply in place in minutes according to the demand for one concrete slide;

[0010] The invention patent (application number: CN201210539585.5) discloses the method of slipform construction in a high temperature and large temperature difference environment. The concrete is prepared in sections according to the air temperature, and the amount of admixture and ice used are adjusted in sections. The speed of concrete slipform pouring is controlled in sections according to the air temperature, and the strength of the concrete out of the mold is taken as the standard. The template is intermittently lifted for slipform construction according to the temperature difference.

[0011] The invention patent application (application number: CN201210119464.5) discloses a method for construction of slipforms in high temperature environments. The method includes: selecting suitable admixtures; dividing the daily temperature into time segments according to the large temperature difference between day and night, and then setting the concrete mix ratio in segments; adding ice cubes when mixing concrete, mixing with concrete tankers, etc., to reduce the temperature of concrete entering the mold; adopting an intermittent lifting process during slipforms; covering the surface of the poured concrete with cotton felt and adopting annular spraying maintenance measures;

[0012] The invention patent application (application number: CN201810441300.1) discloses a method for cooling the silo slipform template under high temperature environment, which includes the following steps: a. setting an ice water system for the slipform platform; b. setting a template insulation layer, wherein: when the template cooling system is working, ice water is sprinkled on the template on the inner and outer hangers of the slipform to cool it down, and the white absorbent cotton cloth wrapped around the steel template absorbs water, so that the steel template is cooled as a whole, and the concrete in the template is cooled down, which effectively avoids the excessive increase of concrete temperature under high temperature conditions, effectively reduces the surface temperature of concrete, ensures the quality of concrete in silo slipform construction under extremely high temperature climates, reduces the impact of extremely high temperature weather, and ensures the continuity of silo slipform pouring;

[0013] The invention patent application (application number CN201810502152.X) discloses a cooling device for a cylindrical wall sliding formwork and a cooling and moisturizing system, wherein the cooling device includes a water storage device, an ice water storage device, and a spraying device. The water in the water storage device is transported to the ice water storage device, and then the water in the ice water tank is sprayed onto the sliding formwork through the spraying device, thereby cooling the sliding formwork. The cooling and moisturizing system includes a sliding formwork system, a heat insulation and moisturizing system, and a cylindrical wall sliding formwork cooling device. The system uses ice water spraying for cooling, which effectively reduces the temperature difference between the formwork surface and the inside of the concrete, thereby keeping the internal and surface temperatures of the concrete consistent, and the solidification time of the concrete inside and outside consistent, which plays a key role in accurately grasping the formwork lifting time and controlling cracking caused by the inconsistent solidification time of the concrete inside and outside.

[0014] However, although the above-mentioned prior art has provided some special methods for slipform construction in an environment with high temperature and large temperature difference, and has achieved good results, it has not provided a clear solution or direct method inspiration on how to overcome the problem of severe temperature difference between the positive and negative sides of the concrete structure caused by strong sunlight, resulting in asynchronous strength growth of the positive and negative sides of the concrete, causing concrete collapse or cracking during the concrete lifting process. Summary of the invention

When the temperature sensed by the temperature sensing device exceeds the specified temperature, the valve of the ice water tank is opened to release ice water and pour it onto the thermal insulation geotextile through the sprinkler pipe until the temperature on the thermal insulation geotextile reaches the specified requirement.

[0027] Furthermore, the thermal insulation geotextile is cut according to the size of the rib separation area on the back of the template, and then four layers of the cut thermal insulation geotextile are overlapped and placed in the rib separation area on the back of the template and fixed with wooden strips.
