Description

Technical Field

[0001] The present invention relates to the field of intelligent building construction and manufacturing, and in particular to a concrete cavity intelligent detection construction method and a vibration construction device. Background Art

[0002] Concrete is in a slurry state before solidification, and has both fluid and colloidal properties. After the concrete pump truck pours it into the mold, it will produce cavities, which will seriously damage the overall strength of the concrete after solidification.

[0003] Traditional methods use flat-plate vibrators or inserted vibrators to stir the setting concrete, increasing its fluidity and allowing the flowing concrete to fill the cavity. However, this method does not allow construction workers to monitor the location of the cavity or determine the filling status.

[0004] Patent publication number CN209920122U discloses a vibrator for vibrating precast concrete components, relating to the field of green concrete construction. The vibrator comprises a chassis, a motor mounted on the chassis via a motor mounting bracket, the motor output shaft extending through the chassis top wall and connected to a lifting mechanism, the lifting mechanism connected to one end of a moving rod, the other end of which extends through the chassis bottom wall and connected to a compacting mechanism located below the chassis, an outer rod disposed within the chassis, the outer rod having a cavity, a limit block disposed within the cavity, the limit block connected to one end of an inner rod, the other end of the inner rod extending through the chassis bottom wall and connected to the compacting mechanism, the inner rod being sleeved with a spring A, located between the chassis bottom wall and the outer rod. The device compacts the precast concrete components through the compacting mechanism, thereby preventing bubbles from forming within the precast concrete components and improving their strength. Furthermore, the device assists the compacting mechanism with the auxiliary vibration mechanism, further enhancing the compaction effect of the device.

[0005] However, the above solution cannot perform vibration filling construction on the cavity of the concrete to be solidified. Summary of the Invention

[0006] The purpose of the present invention is to overcome the above-mentioned problems existing in the prior art and to provide a concrete cavity intelligent detection construction method and a vibration construction device for performing vibration filling construction on the cavity in the concrete to be solidified.

[0007] In order to achieve the above technical objectives and the above technical effects, the present invention is implemented through the following technical solutions: A concrete cavity intelligent detection construction method, the detection construction method comprising: Detect and obtain the location of the cavity area of ​​the concrete to be solidified; Detect and obtain the spatial position and posture of the vibrator; The vibrating rod is moved to the construction position according to the position of the cavity area of ​​the concrete to be solidified.

[0008] Furthermore, the detecting and obtaining of the position of the cavity area of ​​the concrete to be solidified includes: Apply vibration waves to the concrete to be solidified. The echo of the vibration wave is detected to obtain the position of the cavity area of ​​the concrete to be solidified.

[0009] Furthermore, the step of applying vibration waves to the concrete to be solidified and detecting echoes of the vibration waves to obtain the position of the cavity area of ​​the concrete to be solidified includes: applying pulse vibration waves emitted at intervals to the concrete to be solidified; The edge of the cavity area of ​​the concrete to be solidified reflects the vibration wave to form a reflected wave; receiving a reflected wave reflected from an edge of a cavity area of ​​the concrete to be solidified, and analyzing the time, amplitude, and azimuth of receiving the reflected wave; According to the time, amplitude and azimuth of the received reflected wave, a reflection surface space model is constructed, wherein the reflection surface space model includes the edge of the cavity area of ​​the concrete to be solidified and the edge of the concrete mold. For pulse vibration waves with interval reflections, a spatial model of the reflection surface can be constructed based on the reception time, amplitude, and azimuth. The difference in reception time and the degree of amplitude attenuation can be used to determine the relative distance between the reflection point and the receiving position, and then the relative position can be determined in combination with the azimuth. The relative positions of all reflection points are combined to obtain the spatial model of the reflection surface. Screening out the edge of the cavity area of ​​the to-be-solidified concrete in the reflection surface space model to obtain the position of the cavity area of ​​the to-be-solidified concrete; When the vibration echo in the concrete to be solidified is attenuated to a level that does not affect the reception of the reflected wave at the edge of the cavity area of ​​the concrete to be solidified, the above steps are repeated to apply the pulsed vibration wave emitted at intervals to the concrete to be solidified.

[0010] Furthermore, the step of applying vibration waves to the concrete to be solidified and detecting echoes of the vibration waves to obtain the position of the cavity area of ​​the concrete to be solidified includes: Applying vibration waves with periodic phase changes to the concrete to be solidified. Compared with pulsed vibration wave detection, the continuous emission of phase-changing vibration waves can continuously detect the concrete to be solidified and issue construction instructions to construction workers in real time, further improving construction efficiency. The edge of the cavity area of ​​the concrete to be solidified reflects the vibration wave to form a reflected wave; Receive the reflected wave from the edge of the cavity area of ​​the concrete to be solidified, and analyze the time, amplitude, azimuth and phase of the received vibration wave; According to the reception time, amplitude and azimuth of the reflected wave with the same phase, a reflection surface space model is constructed, wherein the reflection surface space model includes the edge of the cavity area of ​​the concrete to be solidified and the edge of the concrete mold. Reflected waves with the same phase indicate that they were transmitted at the same time. In this case, a spatial model of the reflection surface can be constructed based on the receiving time, amplitude, and azimuth. The difference in receiving time and the degree of amplitude attenuation can be used to determine the relative distance between the reflection point and the receiving position. The relative position can then be determined in combination with the azimuth. The relative positions of all reflection points are combined to obtain the spatial model of the reflection surface. Screening out the edge of the cavity area of ​​the to-be-solidified concrete in the reflection surface space model to obtain the position of the cavity area of ​​the to-be-solidified concrete; When the initial phase echo of the vibration echo in the to-be-solidified concrete does not affect the reception of the reflected wave at the edge of the cavity area of ​​the to-be-solidified concrete, the phase cycle ends and is repeated.

[0011] Furthermore, the method of screening out the edge of the cavity area of ​​the concrete to be solidified in the reflection surface space model to obtain the position of the cavity area of ​​the concrete to be solidified includes: Differentiating the blurriness of edges in the reflecting surface spatial model; The physical interface at the edge of the cavity area of ​​the concrete to be solidified is the slurry-gas mixing area, which produces position jitter under the impact of the vibration wave, and the edge obtained by the reflected wave is relatively fuzzy; The physical interface of the edge of the concrete mold is a rigid concrete mold, which remains rigid under the impact of the vibration wave, and the edge obtained by its reflected wave is relatively clear; The fuzzy edge part in the reflection surface space model is used as the edge of the cavity area of ​​the concrete to be solidified; The position of the area occupied by the edge of the cavity area of ​​the concrete to be solidified is used as the position of the cavity area of ​​the concrete to be solidified.

[0012] Furthermore, the step of instructing the vibrating rod to move to the construction position according to the position of the cavity area of ​​the concrete to be solidified includes: Constructing a spatial position model of the concrete to be solidified according to the position of the cavity area of ​​the concrete to be solidified; Conduct operational simulation on the established spatial position model of the concrete to be solidified and plan the working path of the vibrating rod; Move the vibrating rod to the construction position according to the vibrating rod's working path instructions.

[0013] A concrete cavity intelligent vibration construction device, wherein the vibration construction device can at least implement any one of the above-mentioned detection construction methods.

[0014] Furthermore, the vibration construction device includes: A flat tray carrying a vibration generator, which sends vibration waves downwards and is also equipped with a reflected wave receiver; The vibration generator drives the vibration rod to generate vibration. It also includes an indicating device for indicating that the vibrating rod moves to a construction position.

[0015] Furthermore, the indicating device includes a spherical indicator light array located on the vibrating rod, which indicates the vibrating rod to move to the construction position according to the position and posture of the vibrating rod and the position of the cavity area of ​​the concrete to be solidified.

[0016] Furthermore, the indicating device includes a wearable device worn by the construction workers. The wearable device collects environmental images and superimposes the position image of the cavity area of ​​the to-be-solidified concrete on the environmental image, so that the construction workers can conveniently observe the cavity and its position in the to-be-solidified concrete in real time.

[0017] Vibration filling construction is carried out on the cavities in the concrete to be solidified; the position of the cavity area of ​​the concrete to be solidified, the spatial position and posture of the vibration rod are detected and obtained, and the vibration rod is moved to the construction position according to the position of the cavity area of ​​the concrete to be solidified, so as to eliminate the cavities in the concrete to be solidified in a targeted manner, improve construction efficiency, and effectively avoid the existence of cavities in the concrete, which affects the structural strength of the concrete after solidification.
