When the telescopic pipe is used, a line is pulled according to the datum point placed by the total station, a point is found on the line to serve as a starting point, the length of the telescopic pipe is fixed, the lengths are guaranteed to be the same, and the placing point can be performed.
The telescopic pipe comprises a fixed pipe, a first telescopic pipe and a second telescopic pipe which are sleeved together, wherein locking devices are arranged at the ends of the fixed pipe and the first telescopic pipe, so that the length of the telescopic pipe can be locked conveniently.
Preferably, the locking device is a butterfly bolt.
Furthermore, scales are arranged on the first telescopic tube and the second telescopic tube, and the stretching length of the telescopic tube can be visually seen.
Preferably, the sleeve is detachably connected with the telescopic pipe so as to replace sleeves with different diameters, adapt to slurry spraying piles with different diameters and meet the requirements of various working conditions.
The outer wall of the sleeve is provided with an inserting pipe which can be inserted with two ends of the telescopic pipe, and the inserting pipe is limited by a fixing bolt after being inserted with the telescopic pipe.
Compared with the prior art, the utility model has the following beneficial effects:
the three-point positioning device for the slurry spraying pile has a simple structure, and accurate positioning of the slurry spraying pile, and can ensure that three points form an equilateral triangle; the use is convenient, and the labor is saved; the device can be recycled, and construction cost is saved.

Detailed Description
The utility model will be further illustrated with reference to specific examples.
However, the description of the present utility model is merely an embodiment of a structural or even functional description, and the scope of the claims of the present utility model is not limited by the embodiments described herein.
For example, the embodiments may have various modifications and various forms, and it is to be understood that the scope of the claims of the present utility model includes equivalents capable of realizing the technical idea.
As shown in fig. 1 to 5, the present embodiment is realized by the following technical scheme: the telescopic pipe comprises three sleeves 1 and two telescopic pipes 2, wherein the telescopic pipes are made of stainless steel, so that corrosion resistance is improved, and service life under construction working conditions is prolonged. One end of each telescopic tube 2 is connected to the same sleeve, an included angle between the two telescopic tubes 2 is 60 degrees, and the other two sleeves are respectively connected to the other ends of the two telescopic tubes 2.
The telescopic tube 2 of this embodiment comprises a fixed tube 21, a first telescopic tube 22 and a second telescopic tube 23 which are sleeved together, the ends of the fixed tube 21 and the first telescopic tube 22 being provided with locking means 3 (butterfly bolts). The same parts forming the two sets of telescopic tubes 2 have the same length, scales are arranged on the first telescopic tube 22 and the second telescopic tube 23, the stretching length of the telescopic tubes can be visually seen, and the two telescopic tubes 2 are ensured to have the same length.
The sleeve 1 and the telescopic tube 2 of the present embodiment are detachably connected. Specifically, the outer wall of the sleeve 1 is welded with a plugging tube 11 which can be plugged with two ends of the telescopic tube 2, and after the plugging tube 11 is plugged with the telescopic tube 2, the telescopic tube is then plugged with a fixing bolt 4 for limiting. Thereby changing the sleeve with different diameters, adapting to the slurry spraying piles with different diameters and meeting the requirements of various working conditions.
When the telescopic pipe is used, a line is pulled according to the datum point placed by the total station, a point is found on the line to serve as a starting point, the length of the telescopic pipe is fixed, the lengths are guaranteed to be the same, and then the point placement can be performed.
