Problems solved by technology
[0004] The purpose of the present invention is to overcome the problem existing in the prior art that the prefabricated fair-faced concrete components are installed in coastal areas, such as coastal bridges, sea-crossing bridges, artificial islands, etc., and the air humidity is relatively high, and long-term rainfall is extremely harmful to concrete. ; For the prefabricated fair-faced concrete components with high appearance requirements and high installation precision, the traditional pouring method is time-consuming, laborious, and inefficient, and the above-mentioned deficiencies, a fair-faced concrete pouring method is provided

Embodiment
[0027] Such as figure 1 Shown, a kind of fair-faced concrete pouring method of the present invention comprises the following steps:
[0028] A. Concrete is poured by hoisting the hopper into the mold, and the height of the discharge is controlled not to exceed 20cm, so as to avoid a large amount of concrete slurry splashing;
[0029] B. The pouring of prefabricated fair-faced concrete components is divided into three layers, and the pouring of each layer does not exceed 30cm. Every time a layer of pouring is completed, an attached vibrator is used to vibrate once to prevent resonance and damage the formwork. The vibrator is set at the bottom of the mold, and its force is transmitted from bottom to top;
[0030] C. After all the concrete pouring of the prefabricated fair-faced concrete components is completed, the plug-in vibrator is used for re-vibration, and the plug-in vibrator is quickly inserted and slowly pulled out to assist in the discharge of air bubbles;
[0031] D....

The invention discloses a water concrete pouring method. The water concrete pouring method comprises the steps that A, a material hopper is used to hoist concrete to enter a mold for being poured; B,material distributing pouring of a precast water concrete member is divided into three layers, and an attachment type vibrorammer is used to vibrating-ram as each layer of material distributing pouring is completed; C, after all concrete pouring of the precast water concrete member is completed, an inserting-in type vibrorammer is used to vibrate again; D, after the vibrating ramming is completed,primary concrete face finishing is conducted, and it is ensured that the surface of the concrete and a template are aligned; E, after 3-5 hours, secondary concrete face finishing is conducted after the initial coagulation of concrete, and the concrete is pressed to be compacted; and F, finally, slurry increasing and face finishing are conducted after the final concrete coagulation. By means of the water concrete pouring method, the attachment type vibrorammer is used to vibrating-ram the concrete thoroughly without dead angles, by being combined with the inserting-in type vibrorammer for vibrating-ramming, the concrete is uniform and dense, the concrete finished product member is straight and smooth in linear, the visual effect is white and clear and is in a mirror face, the touch feelingis smooth and delicate, any concrete appearance defect does not exist, and the method is simple in step, convenient to use and good in effect.
Description
technical field [0001] The invention relates to the field of civil engineering, in particular to a clear water concrete pouring method. Background technique [0002] Fair-faced concrete has been developed in my country since the 1970s. Due to the objective demand for green buildings and the continuous improvement of people's awareness of environmental protection, the idea of returning to nature is deeply rooted in the hearts of the people. As we all know, the water absorption rate of the concrete surface is relatively high. In the natural environment, the concrete will be damaged by sunlight, ultraviolet rays, acid rain, oil gas, oil pollution, etc., and gradually lose its original appearance. The concrete will also be neutralized and destroyed over time. , its surface effect will become increasingly dirty, affecting the view. Therefore, 60% of fair-faced concrete depends on the quality of concrete pouring, and 40% depends on the transparent protective spraying constructi...
