As shown in fig. 1, the invention provides a flow chart of a concrete vibrating method with a more complex structure for a reinforced embedded part, which specifically comprises the following steps:
s10: establishing a three-dimensional model of the concrete structure, and dividing the three-dimensional model at equal heights to form a plurality of pouring sections;
s20: dividing each pouring section into a plurality of vibrating areas, and numbering the vibrating areas;
s30: planning embedded parts in each vibrating area, and avoiding position planning vibrating points of the embedded parts;

s50: and pouring each pouring section from bottom to top in sequence, vibrating at the position of a vibrating point by using a vibrator, and monitoring the vibrating state in real time, and if abnormal conditions exist, timely processing.
It should be noted that, the pouring of column concrete adopts the car pump to pour, and every 6 posts are a set of, circulation unloading. When the column top is used for discharging, the free falling height is not more than 2m, for example, more than 2m, a string cylinder is additionally arranged, and ash is uniformly discharged. And (3) casting the column concrete once, finishing casting height exceeding the beam bottom by 2cm, and removing the column concrete when the beam is constructed. And (3) after the concrete strength reaches 1.2Mpa, performing construction joint treatment, removing the floating slurry layer until stones are exposed, and washing the concrete with water. Before the concrete is poured, cement mortar with the thickness of 5-10 cm and the same mixing proportion of the concrete and the stone is deducted, so that the cement mortar is combined with the lower concrete tightly. When the concrete is poured in layers, the layering thickness is controlled within 500mm. When the concrete is poured, the pouring speed of the pumped concrete is high, and the column part template needs to be corrected for the second time, namely, the correction is performed again after the concrete is poured. The casting layering thickness is as follows: the thickness of the pouring layer is less than or equal to 1.25 times of the length of the action part of the vibrating rod. In the invention, 50 vibrating bars are adopted in the concrete pouring process of the middle column, the length of an acting part is 38.5cm, and the layering thickness of the concrete is 450mm. And (3) manufacturing a concrete pouring thickness control rod on site, detecting at any time, and adjusting the concrete pouring thickness. When concrete is dusted, the flashlight is used for lighting and reading data on the thickness control rod, so that the casting thickness is controlled. The vibration time of concrete vibration is determined by observing that the surface of the concrete is flooded with slurry, no obvious sinking occurs, no bubbles occur any more, and the concrete vibration is required to be compact.
When the beam and plate concrete is poured, a scaffold board is paved on the special steel bar split heads to serve as a pouring horse way so as to prevent the steel bars from being stepped on and deformed. The beam and the slab are poured simultaneously, the pouring method starts to make the cement from one end, the vibrating hands are closely matched, the concrete is kept to advance along the bottom of the beam by a slurry-driving method, the beam is poured in layers according to the height of the beam, and the beam and the slab are poured together after reaching the bottom of the slab. The vibrator and the flat vibrator are matched for vibration, the vibrator is inserted and pulled slowly, and the insertion points are even. The face adopts the flat vibrator, and with the laser leveling machine flattening along with vibrating, the artifical cooperation flattening in local corner, smears the benefit and prohibits the person to trample. The beam column joint steel bars are dense, small vibrating bars with phi 30 are used for vibrating, and small steel bars are prepared for manual auxiliary vibrating.
In the above technical solution, in step S10, the step of dividing the three-dimensional model into equal heights to form a plurality of pouring segments specifically includes:
the height of each pouring section is determined according to the structural characteristics of the concrete structure and the density of the reinforcing steel bars, and the height of each pouring section is 1.25 times of the length of the acting part of the vibrator, and the maximum height is not more than 500mm.
Further, in the above technical solution, step S20 specifically includes the following steps:
the method comprises the steps of firstly, establishing a coordinate system so that the height direction of the concrete structure coincides with the z-axis of the coordinate system, the length direction coincides with the x-axis, and the width direction coincides with the y-axis;
dividing each pouring section into a plurality of vibrating areas;
and thirdly, recording an x coordinate, a y coordinate and a z coordinate at the central position of each vibrating area as the serial numbers of the vibrating areas.
Further, in the above technical solution, the rule for planning the vibration point in step S30 is as follows:
(1) Selecting the vibration density by combining the slump of the concrete;
(2) Selecting vibrating time by combining the self-fluidity of the concrete;
(3) Selecting a vibrating mode by combining the construction requirement of the concrete and the shape of the concrete;
(4) Selecting vibration points according to the volume, shape and arrangement condition of the steel bars of the concrete, the type, parameters and application range of the vibrator and the environmental conditions of the poured concrete, such as the temperature, wind speed and humidity of the concrete;
after the vibration points are planned, the coordinates of each vibration point are recorded based on a coordinate system.
The vibration density refers to the number of vibrations to be applied to the concrete per unit time. The size of the vibration density reflects the full degree of vibration, and has great influence on the compactness, strength and performance of concrete. In general, the vibration density is closely related to the slump of concrete, and concrete having a large slump requires a large number of vibration times. In the construction process of different concretes, proper vibrating density should be selected to realize the best compacting effect.
Proper vibrating time is selected, so that the fluidity of the concrete can be utilized to the greatest extent, and the compaction of the concrete is promoted. Before vibrating, the concrete should be properly waited for self-flowing, and the vibrating is started after the self-flowing reaches a preset height, so that the concrete can be vibrated in the optimal fluidity state, and the cavities and defects in the concrete are effectively reduced.
The vibration mode is usually edge vibration, comprehensive vibration, internal vibration and the like.

(1) The embedded parts are arranged at intervals, at intervals and in distribution so as to avoid overlapping;
(2) The embedded part is arranged to be parallel to the main stress direction of the concrete, so that the structural performance of the embedded part is improved to the greatest extent.
