[0022] Embodiment 2, on the basis of embodiment 1, as Figure 8 , Fig. 9As shown, pouring concrete and vibrating are performed based on a multifunctional pouring pipe device 3, which includes: The pouring pipe 31 has an upper end connected to a discharge port of a concrete delivery device through a feed pipe (the concrete delivery device may be a concrete delivery pump; during concrete pouring, the concrete is delivered to the pouring pipe through a concrete delivery pump for pouring, which is a prior art, such as CN220132681U and CN219768655U). A through hole 3101 parallel to the pouring pipe 31 is provided in the middle of the shell 316. The through hole 3101 passes through the upper and lower ends of the shell 316. The through hole 3101 passes through the upper and lower ends of the shell 316. 01 is slidably sleeved on the outside of the pouring pipe 31 along the axial direction of the pouring pipe 31, a second through hole 3102 is set at the lower end of the left part of the shell 316, an elastic sleeve 32 is fixedly set in the second through hole 3102, and the vibrating rod 33 slides through the second through hole 3102 along the up and down direction, and the inner side of the elastic sleeve 32 is fixedly sleeved with the outer side of the vibrating rod 33, and the vibrating rod 33 is connected to the vibrating power device through the connecting pipe 4 (this is the prior art, such as CN220080824U, CN218375323U); A vertical telescopic rod 35, the upper end of which is connected to a connecting block 34 provided on the pouring pipe 31, and the lower end of which is connected to the upper end of the housing 316; the vertical telescopic rod 35 can be an electric telescopic rod or a manual telescopic rod; Two groups of left-right symmetrical sealing components, the left sealing component includes: a block 36, the left side of the block 36 is fixedly connected to the left inner wall of the shell 316, and the right side of the block 36 is provided with a slope 361 with a lower left side and a higher right side; a sealing block 37 slides along the left-right direction and penetrates the left side of the casting pipe 31, a horizontal connecting rod 38 is provided on the left side of the sealing block 37, a connecting block 2 39 is provided on the upper end of the horizontal connecting rod 38, a spring 310 is fixedly connected between the connecting block 2 39 and the left inner wall of the casting pipe 31, and an arc surface 381 is provided on the left side of the horizontal connecting rod 38, and the arc surface 381 is used to contact the inclined surface 361 on the corresponding side; Optionally, a block 2 311 is provided on the upper right side of the vibrating rod 33, and a slope 2 312 is provided on the right side of the block 2 311, and the slope 2 312 is lower on the left and higher on the right; a horizontal groove 315 is provided on the left side of the lower part of the casting tube 31, and the right part of the horizontal telescopic rod 313 is slidably connected to the horizontal groove 315, a spring 2 314 is connected between the horizontal groove 315 and the right end of the horizontal telescopic rod 313, and an arc surface 2 3131 is provided on the left end of the horizontal telescopic rod 313, and the arc surface 2 3131 is used to contact the slope 2 312.

[0023] The lower end of the pouring pipe 31 is detachably connected with a guide pipe 5, and the discharge direction of the guide pipe 5 can be toward the vibrating rod 33; The working principle and beneficial effects of the above technical solution are: 1. When pouring, if Figure 8As shown, the vibrating rod 33 is at a higher position, so as to avoid the vibrating rod 33 taking up more concrete pouring space; 2. When vibrating, Figure 8 On the basis of the above, the vertical telescopic rod 35 is controlled to extend downward, driving the shell 316 to move downward, and the vibrating rod 33 is driven downward by the elastic sleeve 32, so that the vibrating rod 33 is inserted into the vibrating position; and when the shell 316 moves downward until the arc surface 1 381 contacts the inclined surface 1 361, the shell 316 continues to move downward, and the arc surface 1 381 on the left and right sides and the corresponding inclined surface 1 361 are contacted and matched, so that the left and right horizontal connecting rods 38 are close to each other, until the right side of the sealing block 37 on the left contacts the left side of the sealing block 37 on the right, so that the left and right sealing blocks 37 seal the inner channel of the pouring pipe 31 where they are located, so as to realize the automatic stop of concrete downward discharge and pouring; When the shell 316 moves downward until the second arc surface 3131 contacts the second inclined surface 312, the shell 316 continues to move downward, and the contact between the second arc surface 3131 and the second inclined surface 312 causes the horizontal telescopic rod 313 to move rightward to compress the second spring 314. Due to the limitation of the compression performance of the second spring 314, the horizontal telescopic rod 313 cannot move rightward after moving to a certain position. At this time, the left part of the horizontal telescopic rod 313 limits the second block 311 to prevent the second block 311 from continuing to fall (especially when the vibrating rod 33 is disconnected from the shell 316, the above-mentioned limit prevents the vibrating rod 33 from falling); The length of the adjustable horizontal telescopic rod 313 can be adjusted to adjust the limiting height of the block 2 311 to meet different limiting requirements.

[0024] 3. The sealing of the channel in the casting pipe 31 and the downward movement of the vibrating rod 33 to a suitable position can be achieved through a vertical telescopic rod 35 and a driving member, so that the vibrating rod 33 can be inserted into the vibrating position and the control is convenient.

[0026] Specifically, the vibration effect evaluation value of each vibration test is calculated based on the following formula;

[0027] is the vibration effect evaluation value of the sth vibration test of the ith concrete sub-unit area corresponding to the kth concrete area sub-model that needs to be vibrated; is the mass of concrete in the ith concrete sub-unit area corresponding to the kth concrete area sub-model that needs to be vibrated; is the maximum distance between the center of the vibrating rod 33 and the i-th concrete sub-unit area corresponding to the k-th concrete area sub-model that needs vibration during the s-th vibration test of the i-th concrete sub-unit area corresponding to the k-th concrete area sub-model that needs vibration when the j-th vibrating rod 33 stays at the vibration position; e is a natural constant; The actual vibration frequency of the vibrating rod 33 when the j-th vibrating rod 33 stays at the vibrating position during the s-th vibration test of the i-th concrete sub-unit area corresponding to the k-th concrete area sub-model that needs to be vibrated; The actual amplitude of the vibrating rod 33 when the j-th vibrating rod 33 stays at the vibrating position during the s-th vibration test of the i-th concrete sub-unit area corresponding to the k-th concrete area sub-model that needs to be vibrated; is the total number of vibrating positions where the vibrating rod 33 stays during the s-th vibration test of the ith concrete sub-unit area corresponding to the k-th concrete area sub-model that needs to be vibrated; The vibration duration of each stop vibration position of the vibrating rod 33; When it is less than the first preset value, The value is 0 ( Large, poor vibration effect, no measurement); When it is greater than or equal to the first preset value, The value is 1, d is the evaluation setting coefficient; Q is the pouring speed of concrete; t is the unit time; It is the maximum vertical distance between the outlet of the pouring pipe during concrete pouring and the i-th concrete sub-unit area corresponding to the k-th concrete area sub-model that needs to be vibrated; is the concrete temperature before vibration; is the average temperature of the concrete after the s-th vibration test in the ith concrete sub-unit area corresponding to the k-th concrete area sub-model that needs to be vibrated; is the target temperature of the concrete; for Corresponding vibration effect evaluation coefficient (obtained based on a preset function or association table); for Corresponding vibration effect evaluation coefficient (obtained based on a preset function or association table); for Corresponding vibration effect evaluation coefficient (obtained based on a preset function or association table); for The corresponding target value; They are the first evaluation weight, the second evaluation weight, and the third evaluation weight (all values ​​are greater than 0 and less than 1); is the vibration effect correction coefficient of the sth vibration test of the ith concrete sub-unit area corresponding to the kth concrete area sub-model that needs to be vibrated; is the theoretical damping of the concrete to be vibrated; is the natural logarithm; The units 36 and 16 are both degrees Celsius.

[0034] It is the average value of the amplitude monitored by the vibration monitoring device during the current test duration; For combination The power correction coefficient obtained (obtained based on the preset corresponding parameter association table or obtained based on the preset function, the value is greater than -1 and less than 1); The standard deviation of the amplitude monitored by the vibration monitoring device during the current test duration; The maximum value of the amplitude monitored by the vibration monitoring device during the current test duration; The minimum value of the amplitude monitored by the vibration monitoring device during the current test duration; The number of times the absolute value of the difference between the two detection values ​​of the vibration monitoring device before and after the current test duration is greater than the preset amplitude difference; For combination The power correction coefficient obtained (obtained based on the preset corresponding parameter association table or obtained based on the preset function, the value is greater than -1 and less than 1); The beneficial effects of the above technical solution are: First, based on the current target vibration parameters of the concrete, the parameters of the vibrating motor, and the material parameters of the concrete (the material of the above concrete is a theoretical parameter or a test parameter), the theoretical power P required to achieve the target amplitude of the concrete under the condition that the vibrating motor can work normally is calculated. The current concrete vibration test duration is measured with the theoretical power as the actual working power of the vibrating motor, and the vibration monitoring device is controlled within the test duration. The amplitude of the vibrating rod 33 is monitored again. When the ratio of the average value of the amplitude monitored by the vibration monitoring device to the target amplitude of the concrete is less than or equal to a second preset value, an alarm is sounded through the alarm device. This indicates that the vibration effect of the current vibrating motor is abnormal and the vibrating motor needs to be repaired.

[0035] When the ratio of the average value of the amplitude monitored by the vibration monitoring device to the target amplitude of the concrete is greater than the second preset value and less than or equal to the third preset value (the third preset value is greater than the second preset value, and both the third preset value and the second preset value are less than 1), it means that the actual amplitude of the concrete still cannot reach the target amplitude of the concrete. This may be due to slight errors between the material parameters of the concrete in the formula and the actual ones and / or small changes in the long-term performance of the vibrating motor. In order to achieve the target amplitude of the concrete, it is necessary to adjust the actual working power of the vibrating motor to the target power to ensure the vibration effect on the concrete.
