Embodiment 1

[0066] Example 1, Ground subsidence monitoring

[0067] The scope of the front 10m and the rear 20m of the shield machine nose is observed once a day in the morning and evening, and progresses with the construction progress. Each monitoring is guaranteed to partially overlap with the last observation point for comparison. Monitoring points outside the range shall be observed once a week until stable. When the settlement or uplift exceeds the specified limit (-30 / +10mm) or the change is abnormal, increase the monitoring frequency and detection range, organize timely analysis of the cause of abnormal deformation, and take corresponding measures to control the deformation. High-precision instruments such as NA2002 automatic electronic level and indium steel ruler are used to monitor surface settlement.

Embodiment 2

[0068] Example 2, Ground building monitoring

[0069] Settlement monitoring of buildings within 10m and 20m behind the nose of the shield machine is carried out, once a day in the morning and evening, and once a week after the shield machine passes through the building, until it is stable. For dangerous buildings and buildings with more than four floors, the inclination measurement must be carried out while the settlement is monitored, and cracks must be monitored for buildings with cracks. Use SOKA total station, NA2002 automatic electronic level and indium steel ruler for high-precision monitoring. For important buildings, automatic recorders and finishing devices are used.

Embodiment 3

[0070] Example 3: Underground pipeline monitoring

[0071] Settlement detection of underground pipelines within 10m before and 20m behind the head of the shield machine is carried out, once a day in the morning and evening, and once a week after the past, until stable. The allowable deformation value of important pipelines such as gas pipelines and water pipelines will be confirmed in the pipeline survey after winning the bid. The monitoring of these pipelines should be strengthened. Use SOKA total station, NA2002 automatic electronic level and indium steel ruler for high-precision monitoring. When the maximum displacement value exceeds the maximum warning value, the alarm should be reported in time, countermeasures should be studied, and the measurement frequency should be encrypted to prevent unexpected events until effective measures are taken.

Abstract

The invention belongs to the building technological field and discloses an internet-based subway tunnel construction safety monitoring system. The internet-based subway tunnel construction safety monitoring system comprises a ground subsidence monitoring module, a ground building sinking and tilt monitoring module, an underground pipeline monitoring module, a pile foundation underpinning monitoring module, a communication channel and pump house construction monitoring module, an in-ground vertical displacement and horizontal displacement monitoring module, a groundwater water level monitoringmodule, a rock-soil and tunnel structure interaction monitoring module, and a pipe segment deformation monitoring module. The internet-based subway tunnel construction safety monitoring system provided by the technical schemes of the invention aims at safety detection. According to the internet-based subway tunnel construction safety monitoring system, monitoring objects are determined according to different engineering items; programs are designed according to the main indicators for the safety and stability of the monitoring objects; and the arrangement of monitoring points can fully reflectthe working states of the monitoring objects. With the internet-based subway tunnel construction safety monitoring system of the invention adopted, monitoring performance and precision can be satisfied, detection frequency can be reduced, detection components can be reduced, and monitoring costs can be decreased.

Description

Technical field [0001] The invention belongs to the field of construction technology, and in particular relates to a subway tunnel construction safety monitoring system based on the Internet. Background technique [0002] At present, the existing technology commonly used in the industry is as follows: [0003] With the advancement of technology and economic development, the urban rail transit system has also been used as an indicator to show that the country is superior in economy, society and technology. The vast majority of urban rail transit systems are high-volume and rapid urban public transportation systems used to carry commuter passengers in the city. In many cases, urban rail transit systems will be regarded as the backbone of urban transportation. Generally, the urban rail transit system is the method used by many cities to solve the problem of traffic congestion. Digging a tunnel under the ground is not an easy task, and it requires a lot of money and time, at least se...
