Abstract
Description
Technical Field
[0001] The utility model relates to a deep foundation pit retaining pipe pile, in particular to a tilt early warning monitoring device for the deep foundation pit retaining pipe pile. Background Art
[0002] Some deep foundation pits are surrounded by prefabricated prestressed concrete pipe piles. Concrete crown beams are cast on the tops of the prestressed concrete pipe piles. During the entire construction process of the foundation pit, the status of the prestressed concrete pipe piles needs to be monitored to ensure the safety of the construction in the foundation pit. The existing technology monitors the status of prestressed concrete pipe piles by measuring the verticality of the prestressed concrete pipe piles manually by inspectors using measuring instruments at irregular intervals on the ground outside the foundation pit, and collects the verticality data of the concrete pipe piles. Due to the wide working surface of the foundation pit construction and the complex on-site construction environment, data collection is not timely, and the on-site connection error between the measuring instrument and the prestressed concrete pipe piles is large, resulting in the inclination of the prestressed concrete pipe piles not being discovered in time, and the on-site early warning signal being issued with a lag, which affects the normal and safe construction work in the foundation pit. Summary of the invention
[0003] The utility model provides a tilt early warning monitoring device for deep foundation pit retaining pipe piles, which solves the technical problem that the on-site early warning signal is delayed and affects the normal and safe progress of construction work in the foundation pit.
[0004] The utility model solves the above technical problems through the following technical solutions:
[0005] A tilt early warning monitoring device for deep foundation pit retaining pipe piles comprises a deep foundation pit and a bubble level, wherein prestressed concrete pipe piles are arranged in the deep foundation pit, and a concrete casting crown beam is arranged at the top of the prestressed concrete pipe piles; embedded bolts are arranged on the top surface of the concrete casting crown beam, an observation box body is connected to the embedded bolts, and a bubble level is arranged in the observation box body; a reversible box cover is arranged on the upper port of the observation box body, and the reversible box cover is connected to the upper port of the observation box body through a hinge.
[0006] A bubble level mounting base is arranged on the bottom end surface of the observation box body, and the bubble level is arranged on the bubble level mounting base; three leveling nut embedding holes are respectively arranged on the bottom plate of the observation box body, and the three leveling nut embedding holes are arranged on a concentric circle, and leveling nuts are fixedly arranged in the leveling nut embedding holes, and leveling bolt legs are connected to the leveling nuts; a center through hole is arranged at the center of the bottom end surface of the observation box body, and the upper end of the embedded bolt passes through the center through hole and is connected with the locking nut.
[0007] The utility model sets an observation box body through the embedded bolts on the crown beam, and a bubble level is arranged in the observation box body. The bubble level is used to monitor the inclination displacement of the crown beam, so as to timely discover whether the retaining pipe piles have inclination displacement phenomenon, and timely warn. The permanent observation mechanism of the utility model realizes close monitoring of the retaining pipe piles. The operator can monitor at any time, which effectively reduces the time and labor cost of the monitoring work, and can timely discover the hidden dangers of the inclination of the retaining pipe piles. When the foundation pit construction is completed, the observation box body can be conveniently removed as a whole and transported to the next observation point for installation.
