Description
Technical Field
[0001] The utility model belongs to the technical field of pile verticality monitoring, and particularly relates to a pile verticality monitoring device. Background Art
[0002] If there is a large deviation in the verticality of precast piles during the pile sinking process, it will have a great impact on the construction and use of the main structure. Excessive verticality deviation will cause eccentric force on the pile, which will cause deformation and breakage of the pile foundation. Uneven force can also easily cause uneven settlement of the foundation, causing structural damage and bringing serious safety and quality risks. At present, during the pile sinking process of precast piles, the verticality monitoring of the pile body relies on two theodolites to measure at 90°. This monitoring method has the following shortcomings:
[0003] First, the measurement efficiency is low, the cost is high, and it is not economical;
[0004] Second, due to the use of measuring instruments and numerical calculations, there are certain errors in the measurement results;
[0005] Third, monitoring is difficult to implement, and the monitoring process is affected by the level of measurement personnel and working conditions. Utility Model Content

[0013] As a preferred solution of the utility model, the number of the positioning structures is four, and the four positioning structures are evenly distributed along the circumferential direction on the inner side of the monitoring ring.
[0014] As a preferred solution of the utility model, the monitoring ring includes two semicircular rings, and the two semicircular rings are connected by a flange.
[0015] As a preferred solution of the utility model, the connecting rod includes a sleeve rod, one end of the sleeve rod is connected to the fixed rod, the other end of the sleeve rod is sleeved with a telescopic rod, and the other end of the telescopic rod is connected to the ball joint node. The telescopic rod can move relative to the sleeve rod, so that the length of the connecting rod can be adjusted. The connecting rod connects the monitoring ring to the fixed rod, and the connecting rod is adapted to the displacement of the monitoring ring by telescoping.
[0016] As a preferred solution of the utility model, a collar is fixed on the connecting rod, and the collar is sleeved on the fixed rod. The connecting rod can rotate relative to the fixed rod, so that the position of the monitoring ring is not restricted by the fixed rod, avoiding interference.
[0017] As a preferred solution of the utility model, the lower end of the fixing rod is a pointed end, so that it is convenient to bury the fixing rod near the pile hole.
[0018] The beneficial effects of the utility model are:
[0019] The monitoring ring of the utility model is set on the prefabricated pile, and the monitoring ring can rotate 360 degrees relative to the fixed rod through the ball joint node. When the pile body tilts during the pile sinking process, the monitoring ring moves synchronously with the pile body, so that the verticality monitored by the wireless inclination sensor on the monitoring ring is the actual verticality of the pile body. The monitoring ring is always set on the pile body, and the monitoring of the verticality of the pile body during the pile sinking process is continuous. The monitoring implementation operation is simple, and the monitoring process is not affected by the level of the measurement personnel and the working conditions. BRIEF DESCRIPTION OF THE DRAWINGS
