Description
Technical Field
The invention belongs to the field of civil engineering, relates to a slope monitoring technology, and particularly relates to an anti-slide pile deviation monitoring device and an anti-slide pile deviation monitoring method capable of automatically reading data, which are used for early warning the possible slide of a slope by monitoring the deviation of an anti-slide pile and wirelessly transmitting an alarm to a computer or a mobile phone terminal through induction.
Background
At present, the anti-slip body is mainly a cast-in-place anti-slip pile to prevent the sliding of the side slope, and the anti-slip pile has the impedance effect but cannot ensure that the sliding body of the side slope does not slide.
The slide-resistant pile is used as a main method for slope support, and has the following advantages: (1) higher slip resistance is obtained with smaller masonry amounts. Because the side slope supporting structure is often of a relatively large scale, compared with a retaining wall which needs dead weight to balance rock-soil pressure, the masonry amount is often large, and the reinforced concrete column slide-resistant pile which reasonably utilizes the tensile capacity of the reinforcing steel bars can reduce the masonry amount and simultaneously obtain better slide-resistant capacity. (2) The construction equipment is simple, the construction is safe and convenient, and the construction period is short. Because the construction excavation working face of the slide-resistant pile is small, and the slide-resistant pile can be simultaneously worked in rows, the construction technology is simple. At present, the construction system and the technology of the slide-resistant pile are quite mature. (3) The pile position can be flexibly arranged according to actual needs. Because the anti-slide piles are formed by arranging the reinforced concrete columns one by one, the anti-slide piles can be arranged to the most favorable position for resisting the landslide according to the requirement, and the anti-slide efficiency is increased. (4) When the pile hole is excavated, the geological condition can be directly checked.
The purpose of the anti-slide pile is to resist sliding displacement of the sliding mass. In order to ensure the safety of the side slope, the horizontal displacement increment and the sliding speed of the side slope body need to be observed regularly. The current common mainstream methods for monitoring slippage of the anti-slide pile include: total station monitoring, GPS monitoring, optical fiber sensor monitoring and the like.
The total station monitoring method has the following defects: (1) consuming manpower. Due to the use limitation of the total station, 2-3 persons are required to work simultaneously during observation, and unnecessary manpower is consumed. (2) Limited by the influence of the terrain. Often there is the afforestation on the slope body, because the growth of vegetation can shelter from the sight between total powerstation and the prism to lead to the observation result to appear the deviation. (3) The process is cumbersome. When using a total station, the equipment itself is relatively numerous and heavy and requires high set-up site conditions, which may create unnecessary complications if site geographical conditions are not ideal.
The GPS monitoring method has the following defects: (1) the accuracy is not high. (2) And (4) condition limitation. The method for GPS detection usually requires satellite positioning, and if the monitoring place has dense vegetation coverage, signals of a GPS can be influenced, so that the method cannot be continued. (3) The process is cumbersome. The GPS monitoring method requires many reference points and requires a large distance measurement.
The optical fiber sensor monitoring method has the following defects: (1) the cost is expensive. The optical fiber sensor belongs to a precise electronic sensing instrument, is more expensive than the common traditional instrument, and has a large number of anti-slide piles when put into use. The cost of using the optical fiber sensor is high. (2) And the maintenance of the instrument. Since the optical fiber sensor is a high-precision instrument, the life of the instrument can be greatly shortened under hostile geological environments and weather conditions, and the number of times of manual maintenance can be increased, thereby incurring additional costs. (3) The steps are cumbersome. When installing the fiber optic sensor, wiring is extremely cumbersome and the acquired data requires a complex series of system conversions.

step 3, adjusting the level bubble of the high-precision circular level bubble to a central position through the leveling support, and defining the position of the anti-slide pile at the moment as a vertical initial state;
step 4, connecting the signal detection device of the high-precision circular level bubble with a wireless communication module through a signal wire, and connecting the wireless communication module with a remote control center;
and 5, when the anti-slide pile inclines, the mercury liquid drop freely moves in the spherical groove under the action of self gravity, when the mercury liquid drop moves between the two circular ring scale marks, namely the two circular ring scale marks are conducted, the detection device sends out a detection signal through the wireless communication module, the position of the circular line of the mercury liquid drop is judged through the detection signal, so that the offset angle of the high-precision circular air level is read out, the offset distance of the anti-slide pile is calculated through the sine formula according to the offset angle and the direction of the high-precision circular air level, and when the offset distance of the anti-slide pile is greater than the designed maximum value, a danger early warning is sent out, and the anti-slide pile is reinforced or rebuilt.
