Embodiment Construction

[0067] The present invention will be further described in detail below in conjunction with test examples and specific embodiments. However, it should not be understood that the scope of the above subject matter of the present invention is limited to the following embodiments, and all technologies realized based on the content of the present invention belong to the scope of the present invention.

[0068]

[0069] Prepare four model installations "from small to large". Such as Figure 1-Figure 4 as shown, figure 1 It is a wooden model A design drawing, figure 2 It is the design drawing of wooden model B. The dimensions of wooden model A and wooden model B are both 100cm×100cm×50cm. The only difference is the location of the pouring gate. image 3 It is the design drawing of the small model of the plexiglass compartment. The size of the small model of the plexiglass compartment is 150cm×150cm×75cm. Figure 4 It is a three-dimensional drawing of the plexiglass wall model, ...

Abstract

The invention relates to a performance verification method of high-fluidity concrete of a steel shell, which is characterized by including steps of designing multiple models with different sizes; orderly selecting corresponding models from small to big, and carrying out the test of the high-fluidity concrete. Specific to the construction technique requirement of the high-fluidity concrete of the steel shell, the method applies multiple models orderly to verify the influences of the concrete matching ratio, pouring method, pouring speed and other technical parameters on the concrete filling state one by one, evaluate the high-fluidity concrete filling property, optimize the high-fluidity concrete matching ratio, adjust the construction technical parameter and other factors, and realize thehigh-quality processing and application of the concrete.

Description

technical field [0001] The invention relates to a method for verifying the fluidity of concrete, in particular to a method for verifying the performance of steel-shell high-fluidity concrete, which belongs to the field of building construction. Background technique [0002] The steel-shell immersed tube forms a combined structure by outsourcing the steel shell and the concrete filled in it. The immersed tube joints have an internal space of 0.5m 3 ~13.5m 3 Different individual steel compartments (or compartments) are processed and spliced ​​to form walls, roofs, bottom plates and end panels. After assembly, they are called integral structures, and then concrete is poured into the steel compartments to improve the overall integrity of the pipe joints. stiffness and strength. At present, there is no engineering application case of steel shell immersed tube concrete in China. [0003] In order to ensure the integrity between the steel shell and the concrete, the gap between ...
