Description
Technical Field
The utility model relates to the technical field of bored concrete pile over-irrigation monitoring, in particular to a bored concrete pile over-irrigation monitoring device based on an actual resistivity measurement method.
Background
In the construction of the cast-in-place pile, the phenomenon of over-filling is ubiquitous, and the reasons are as follows: the height of the upper interface of the pure concrete is invisible when the concrete is poured; when concrete is poured, sediment at the bottom of the pile and impurities precipitated in slurry in the pouring process can be accumulated to a certain thickness on the surface of the concrete, and the pile head is easy to form laitance; continuous construction is needed in the pouring process, otherwise, bubbles are generated in the pile to influence the pile forming quality, and in order to ensure the pile quality, over-pouring treatment is carried out in actual construction. But need monitor super-filled concrete, avoid super-filling too much, cause the concrete waste.
Because the liquid level of the super-poured concrete on the construction site is uncontrollable, the super-pouring height is as high as 2-3 meters, the height of each pile is different frequently and is in a shape of a stone forest, so that concrete is wasted due to super-pouring, and more resources are consumed by removing redundant pile heads, so that the super-pouring is necessary to be effectively monitored, and the super-pouring amount is minimum on the premise of ensuring the quality of the piles. The general method for monitoring the super irrigation includes a volume method and a weight drop method. If the aperture of the pile hole is changed in the construction process, controlling the over-irrigation by a volume method to be impossible; the heavy hammer method is based on the experience of workers, and the measurement results vary from person to person, so that the heavy hammer method still has the possibility of generating more uneven super irrigation heights.
The resistivity can be used as a parameter for representing the strength of concrete, and technicians can judge the accurate positions of the concrete and a mud interface layer according to a resistivity conducting mechanism. Patent document CN201410833047.6 discloses a device for monitoring a concrete interface of a bored pile, which can test the electrical impedance and the sensitivity of concrete, slurry, water and other media in the underwater concrete pouring process of the bored pile, and realize the positioning of the concrete pouring interface by measuring the electrical impedance difference between water, slurry and concrete in the pouring process. However, in the pouring process, as the slurry and the concrete are turned over up and down, the fluid medium in the drill hole is changed greatly, the change of the electrical parameter value is violent and not stable, and the measurement of the electrical impedance of the monitoring device on the fluid medium is influenced.

However, the utility model needs to calibrate the concrete parameters before the concrete is poured, the difference between the measuring environment and the actual environment of the poured pile is large, and the preset value cannot be well matched with the concrete parameters in the pouring process; secondly, the device is only provided with a measuring point at the elevation position, and the pouring process of the concrete cannot be stopped immediately even if an alarm gives an alarm; in addition, the resistivity value of each batch of concrete is different, and the influence of the surrounding environment of the drill hole, particularly the steel reinforcement cage on the detection probe cannot be ignored.
