Description

A Multifunctional Auxiliary Equipment for Tunnel Monitoring

technical field

The utility model patent relates to a multifunctional tunnel monitoring auxiliary equipment.

Background technique

Tunnel monitoring and measurement is one of the three pillars of the new Austrian method, which plays an important role in the adjustment of construction technology, the selection of support structures and the selection of support structure parameters during tunnel construction. During tunnel construction, in order to ensure the stability of the surrounding rock around the tunnel and the safety of the tunnel itself, it is necessary to monitor and measure the tunnel during construction.

With the rapid development of urban subway tunnels, the monitoring work in tunnel construction has attracted more and more attention from the owners and construction parties. In tunnel monitoring and measurement work, tunnel vault settlement, tunnel convergence, and tunnel surface settlement are all must-test items for monitoring and measurement. Corresponding to different monitoring items, monitoring personnel need to use different monitoring equipment, so that monitoring personnel need to carry a large number of monitoring equipment, and the monitoring work is labor-intensive. Therefore, there is an urgent need for a device that integrates the devices in the current tunnel monitoring work.

At present, tunnel deformation monitoring is divided into two types: relative displacement monitoring and absolute displacement monitoring; relative displacement monitoring is to understand the deformation of the tunnel through the relative displacement between tunnel observation The coordinates of the points are used to understand the deformation of the tunnel, and a total station is usually used for monitoring.

In view of the fact that the height of the tunnel vault is above 5m, when the total station is used for monitoring, the tunnel vault can only be monitored in the form of pasting reflective sheets. The light in the tunnel is insufficient and the dust is large, so that the total station monitoring The accuracy is low and cannot meet the monitoring accuracy requirements. Moreover, total station monitoring is absolute displacement monitoring, which makes it necessary to frequently retest the base points in the tunnel during the monitoring process. Various conditions restrict the use of total stations in tunnel monitoring and measurement.

At present, relative displacement monitoring technology is widely used in tunnels. This monitoring method is to arrange three or five monitoring points in a section of the tunnel to form a triangular network (as shown in the figure below), and use the tunnel convergence meter to measure the length of the three sides. According to the triangle theorem Then the tunnel vault settlement is obtained. This method has high precision and is easy to operate. However, the extensometer is currently mainly used for monitoring the convergence in the horizontal direction. Due to the high vault of the tunnel, it is difficult to place the hook at one end of the extensometer on the vault during use, which greatly restricts the use of the extensometer.

The above factors indicate that the current monitoring equipment used in tunnel monitoring work is not enough to meet the needs of a large number of tunnel monitoring work. This utility model "a multi-functional tunnel monitoring auxiliary equipment" skillfully combines the currently commonly used upside-down ruler, tunnel convergence meter, and surface settlement tower ruler, and adds some beneficial structures at the same time, making the heavy monitoring work easier. Reduce the burden on monitoring personnel. The utility model can be used for tunnel vault settlement monitoring (upside-down ruler method), tunnel triangular section hypotenuse measurement (convergence meter method), and ground surface settlement monitoring. At the same time, assembly flashlights, LED lights and other components are used to overcome the adverse effects of the dark light in the tunnel on the monitoring work. Assembling a flexible connecting line ensures that when the device is used for monitoring by the upside-down ruler method, the ruler is guaranteed to be in the vertical position. In addition, a tripod is set to ensure that the device is in a vertical position when used for surface settlement measurement to reduce the burden on the ruler. It can be seen that the utility model can solve the above problems, reduce the labor intensity of monitoring personnel, save monitoring time, and further reduce monitoring costs. .
