[0002] With the continuous promotion and application of prestressed concrete pipe piles (PHC), most of the pile foundations in building construction are currently constructed in the form of pipe pile construction. However, according to the traditional pipe pile construction process, the detection of the verticality of the pipe piles basically occurs in the three construction stages of pile positioning, pile sinking (after the pile body is 1 to 2 meters into the soil), and pile connection. The detection object is only the verticality of the pipe piles above the ground, and there is currently no practical detection method or device for the detection of the part below the ground. This results in the fact that after the pipe piles are built, there is no verticality inspection and review, so it is impossible to determine whether the piles have reached the quality standards and meet the requirements of supporting the upper structure, which brings certain quality and safety risks to the entire foundation project. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a device and method for detecting the verticality of a prestressed concrete pipe pile after it is formed. The device can be used to more efficiently solve the problem of detecting the verticality of a prestressed concrete pipe pile after it is formed. The device can be used to detect the verticality of the pile to determine whether the verticality of the pile meets the quality requirements. After a problem is found, rectification and correction can be carried out in time to ensure the quality of pile foundation construction.

[0004] The technical solution adopted by the present invention to solve the technical problem is as follows: a device for detecting the verticality of a prestressed concrete pipe pile after it is formed is provided, comprising a direction pointer, a leveling direction compass and a telescopic probe rod, wherein the upper end of the leveling direction compass is provided with a direction pointer, the middle part of the lower end of the leveling direction compass is rotatably connected with a telescopic probe rod, the upper end of the telescopic probe rod passes through the leveling direction compass and is connected with the direction pointer, the lower end of the leveling direction compass is evenly arranged with a plurality of reversible telescopic legs around the telescopic probe rod, the lower end of the telescopic probe rod is installed with a distance measuring device, the distance measuring device comprises a distance measuring transmitter and a receiver, and the direction pointer is provided with a distance measuring button for remotely controlling the distance measuring device.

[0005] As a supplement to the technical solution described in the invention, a bubble level is embedded and installed on the upper end of the leveling direction compass.

[0006] As a supplement to the technical solution described in the invention, a plurality of storage slots are evenly arranged around the telescopic probe rod at the lower end of the leveling direction compass, and a telescopic leg is rotatably connected in each storage slot.

[0007] As a supplement to the technical solution described in the invention, one end of the telescopic leg is rotatably connected to the inner wall of the retractable groove through a bearing.

[0008] As a supplement to the technical solution described in the invention, a bolt column is provided at the upper end of the telescopic probe rod, and a probe rod bolt hole matching with the bolt column is opened in the middle of the lower end of the direction pointer.

[0009] As a supplement to the technical solution described in the invention, a gasket is installed between the direction pointer and the level direction compass, and the gasket is sleeved on the bolt column.

[0010] As a supplement to the technical solution described in the invention, there are four directions on the leveling compass: east, south, west and north.

[0011] As a supplement to the technical solution of the invention, a data display screen is also installed on the direction pointer.

[0012] A detection method for a verticality detection device of a prestressed concrete pipe pile after pile formation, the specific operation steps are as follows:

[0013] Step 1: Align the bolt column of the telescopic probe with the probe bolt hole of the direction pointer and tighten it, then pass the combined telescopic probe through the leveling compass and rotatably connect it with the leveling compass, install a gasket between the direction pointer and the leveling compass, thus forming a detection device composed of the direction pointer, the leveling compass and the telescopic probe. Then, stretch the telescopic probe to the required length and hang it in the inner hole of the pile.

[0015] Step 3: There is a distance measuring button on the direction pointer that remotely controls the distance measuring transmitter and receiver on the telescopic probe. Adjust the direction pointer in turn according to the four directions of the level compass. The direction of the pointer is the direction in which the distance measuring transmitter and receiver on the telescopic probe are aligned. Press the distance measuring buttons one by one to record the data of the four directions transmitted on the data display screen.

[0016] Step 4: Finally, the verticality deviation of the four directions of the underground pile is calculated by combining the recorded data of the four directions with the standard section length of the telescopic probe extended into the underground part. The verticality deviation of the prestressed concrete pipe piles in the pile foundation project is allowed to be ≤1%. If the deviation is within the allowable range required by the specification, it means that the verticality of the pipe piles meets the quality requirements.

[0040] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0041] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" may include both "above" and "below". The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0042] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.
