Problems solved by technology
[0004] In order to overcome the deficiencies of the existing high formwork and mass concrete structure monitoring, such as manpower, waste of material resources, monitoring accuracy, low efficiency, and difficult monitoring of honeycomb pockmarks, the present invention provides a super large section high formwork and mass concrete structure The deformation monitoring and early warning method can effectively overcome the shortcomings of the above-mentioned conventional large-volume concrete structure deformation monitoring. It can not only monitor the tilt deformation caused by concrete load, wind load and vertical pole foundation settlement, but also further monitor the honeycomb on the concrete beam. In addition, this system also has the characteristics of early warning function, simple operation, convenient operation and high efficiency.

Embodiment Construction
[0034] The present invention will be further described below in conjunction with the accompanying drawings.
[0035] refer to Figure 1 to Figure 7 , a method for monitoring and early warning of deformation of super large-section high-support formwork and large-volume concrete structures, comprising the following steps:
[0036](1) Overhaul the circuit inside the monitor before installing the monitor. The overhaul method is to load batteries into the first power supply compartment 10 and the second power supply compartment 2, and then observe whether there is a current change in the tilting instrument;
[0037] (2) Refer to Figure 5 , Figure 5 The side view of the monitor of this device is shown. Before the installation of the monitor 1, firstly use the keyboard 17 and the screen 16 on the side of the instrument to number the monitors placed on the high formwork beam by a combination of English letters and numbers, so as to accurately monitor each section of the high form...

A large -scale cross -section high -decoration and high -volume concrete structure deformation monitoring and early warning method, including the following steps: (1) the circuit inside the monitor before installing the monitor;The keyboards and screens are numbered to the monitors placed on the high -end model through the combination of English letters and numbers; (3) After the monitor is maintained and installed, you can start monitoring the high -decoration concrete beam.When the high -supporting concrete beam changes due to the stress of concrete or other reasons, the beam body will produce a corresponding tiny bending deformation, then the internal liquid surface of the monitor at the bottom of the beam will change, causing the floating ball to generate a corresponding lift, which will affect the sliding resistor.The resistance value of the resistance, the resistance value of the sliding resistor, the voltage unchanged situation, can accurately reflect the current changes, and the instrument is reflected in the current response instrument.The present invention has early warning functions, simple and easy operation, convenient operation, and high efficiency.
Description
technical field [0001] The invention belongs to the technical field of building construction, and relates to a deformation monitoring and early warning method for super large-section high-support formwork and large-volume concrete structures, which is suitable for deformation monitoring of super-large-section high-support formwork and large-volume concrete structures. Background technique [0002] With the characteristics of large capacity, all-weather, and strong comfort, subway transportation has become an important way to solve the problem of urban public transportation. In order to take advantage of the multi-layered three-dimensional space of the subway station, a parking lot is usually set on the first floor of the subway, and the second floor is covered with a cover plate for comprehensive utilization and commercial development. Concrete structures, high-support formwork and large-volume concrete structures have strict quality control. Improper construction may cause ...
