Problems solved by technology
[0004] In view of the above-mentioned related technologies, the inventor believes that there are the following defects: the connection strength of the steel bar binding acoustic tube is low, and the sound After being impacted by the concrete slurry, the position of the measuring tube tends to deviate relative to the steel cage, which makes the distance between adjacent acoustic measuring tubes change, making it difficult for the acoustic measuring tube to detect at the specified position

Embodiment Construction
[0038] The embodiment of the application discloses a geotechnical engineering pile foundation quality detection structure.
[0039] The following is attached Figure 1-5 The application is described in further detail.
[0040] refer to figure 1 with figure 2 , the detection structure includes a plurality of detection tubes 1 and a positioning piece 2 . In this embodiment, the detection tubes 1 are acoustic tubes, and every four detection tubes 1 are installed in the reinforcement cage 7 through a set of positioning parts 2 . The reinforcement cage 7 is the structural main body of the cast-in-place pile. After the reinforcement cage 7 enters the cavity of the pit excavated on the foundation with the detection tube 1, the concrete slurry fills the pit and consolidates the reinforcement cage 7 to form a cast-in-place pile. At this time, the detection tube 1 passes through the ultrasonic wave in the cast-in-place pile to detect the quality of the molding at a specific positio...

The invention relates to a geotechnical engineering pile foundation quality detection structure and an application method thereof, and relates to the technical field of pile foundation quality detection. The detection structure comprises a plurality of detection pipes, wherein the detection pipes are located in a reinforcement cage used for forming a cast-in-place pile. The detection structure further comprises a positioning piece used for installing the multiple detection pipes at the same time, and the positioning piece comprises a plurality of installation plates and connecting plates; each installation plate is provided with a containing groove allowing the corresponding detection pipe to abut into, the installation plates are provided with abutting arc plates used for pressing and covering the detection pipes, and the abutting arc plates are fixedly connected with the installation plates; and the connecting plates are used for connecting the adjacent installation plates, and the connecting plates are matched with the inner side wall of the reinforcement cage in an abutting manner and are fixedly connected. The application method comprises the steps of positioning, installing and reinforcing. The geotechnical engineering pile foundation quality detection structure and the application method thereof have the effects that the connecting strength of the detection pipes on the reinforcement cage is effectively improved, and the detection stability of the detection pipes at the designated position is guaranteed.
Description
technical field [0001] The application relates to the technical field of pile foundation quality detection, in particular to a geotechnical engineering pile foundation quality detection structure and an application method thereof. Background technique [0002] In geotechnical engineering, the pile foundation is a pile structure that transmits the load of the superstructure downwards and ensures the stability of the superstructure through the strong bearing capacity of the deep foundation. Pile foundations can be divided into various types according to different forming methods, among which cast-in-situ piles are widely used and have relatively high application stability. The formation of cast-in-situ piles is divided into two steps. The first step is to drill a hole on the foundation. The second step is to put a steel cage in the hole and pour concrete slurry. After the concrete slurry is consolidated in the hole, that is Form cast-in-place piles. [0003] In order to dete...
