Boring cast-in-situ pile plagioclase measuring early warning system and method based on video monitoring

Abstract

The invention discloses a boring cast-in-situ pile plagioclase measuring early warning system based on video monitoring. A monitoring module used for video monitoring is arranged opposite to a pile machine, a winch is arranged on one side of a base, multiple auxiliary pulleys are arranged on a support, a steel wire rope extends out of the winch to penetrate through the auxiliary pulleys to be connected with a punch hammer, a pile hole is formed in one side of the base, a steel casing is arranged on the top of the pile hole, the pile hole communicates with a mud pit through a mud pump, multiplemarkers are arranged on the steel wire rope, the monitoring module can record the lifting position and the swing position of the markers, the system and method adopt combination of the monitoring module and the markers, mounting is simple, use is convenient, vertical displacement and horizontal displacement data and the inclination angle of the needed markers can be collected at low cost and highefficiency, through the above data, the inclination angle of the plagioclase can be rapidly calculated, manpower and material resources can be saved, and the construction cost is saved.

Description

technical field [0001] The invention relates to the field of infrastructure construction, in particular to a video monitoring-based system and method for measuring and early warning of inclined rock of perforated piles. Background technique [0002] Pile foundation is the most commonly used form of deep foundation in foundation treatment, which has the characteristics of high bearing capacity and small foundation settlement. However, engineering practice has proved that the rock surface elevation in karst areas is complex and changeable, and there are often inclined rock faces. The piles passing through the inclined rock face often have problems such as hammer jamming, small footage or even no footage during rock entry construction. The actual problems of slow construction progress and increased construction cost are caused. At present, there are still few studies on the slope angle of slope rocks. [0003] The traditional method is to judge whether there is inclined rock ...

AI Technical Summary

Problems solved by technology

[0004] The entire construction process of perforated cast-in-situ piles requires the supervision of construction personnel throughout the process, which requires a lot of manpower and material resources, and there are large instability factors in human monitoring, and construction abnormalities cannot be found in time, resulting in construction quality problems, low efficiency, and high labor costs.

Moreover, the steel wire rope of the pile driver needs to be replaced regularly due to wear and aging during use, and the wear conditions of different construction environments vary greatly, so it is difficult to effectively grasp the timing of replacement
