Description
Technical Field
The invention relates to the field of engineering construction, in particular to a combined device and a method for measuring pile depth, pile diameter and pile hole perpendicularity.
Background
The length of the concrete cast-in-place pile is large, generally up to dozens of meters or even larger, and the control of the perpendicularity and the diameter of a pile hole in the construction process is very important. The most common method for detecting the verticality on site is a plumb bob detection method, generally, a plumb bob is placed at the bottom along the edge of a pile opening, and the distance between the hole wall of each depth and a vertical line is observed by naked eyes, although the method is convenient to operate and simple in material use, the detection result is greatly influenced by human factors, the accuracy is poor, and when the pile is too long, human eyes cannot see; the most common method for detecting the diameter of the pile on site is to directly measure the diameter of the hole, and although the method is quick, the diameter of the hole replaces the diameter of the whole pile, so that the error is large.
The limitations of the plumb bob method have led a large number of construction technicians to study and discuss the perpendicularity measurement of cast-in-place piles, and the device for measuring perpendicularity by using the photoelectric distance meter, which is provided by the patent CN105927213A of Sunrong, Zhang courage and the like, has certain representativeness. The device includes the tripod and sets up the disc at tripod top, and the track is installed along its diameter department in the bottom of disc, and slidable mounting has laser emission and receiver on the track, and laser emission and receiver are along track uniform motion and perpendicular downward transmission laser signal and receive and meet the laser signal that drilling boundary was upwards reflected perpendicularly, measure the displacement on the track of laser emitter simultaneously, utilize right triangle's theorem to calculate the straightness that hangs down of stake. Compared with the traditional plumb bob method, the method has great advantages, but still has more defects:
1. the application range is narrow. If the cast-in-place pile deviates in different directions within the depth range, the whole pile cannot be probed by the vertically downward laser, and the accuracy of the measured data needs to be verified;
2. the accuracy of the instrument is low. Compared with the pulse type distance measuring instrument with the reflector, the pulse type distance measuring instrument without the reflector has the advantages that the accuracy of the measured data is reduced to some extent, the measured data is reduced along with the increase of the measured distance, the depth of a cast-in-place pile can reach dozens of meters generally, and the accuracy of the instrument is difficult to guarantee;
3. the measured data is single. The instrument can only realize the measurement of the verticality, and the main points of the quality control of the cast-in-place pile are the pile depth, the pile diameter and the verticality.
4. Determination of the geographical direction of pile inclination cannot be achieved. During site construction, detection is often separated from later reworking, and if the geographical direction of the inclined pile cannot be accurately recorded, certain difficulty is caused to the later reworking;
5. an accurate three-dimensional model of the pile cannot be formed from the measurement data. If a set of instruments can measure more accurate data, software is used for fitting the three-dimensional image formed by the pile in the later period, and the method has great guiding significance to the rework scheme.
Therefore, the current technical means can not well solve the measurement and detection problem of the cast-in-place pile.
