Description

Technical Field

[0001] The invention belongs to the technical field of tunnel detection, in particular to a quality monitoring device for tunnel construction. Background Art

[0002] Tunnels are engineering buildings buried in the ground. They are a form of human use of underground space. The structure of a tunnel consists of two parts: the main building and ancillary equipment. The main building consists of a tunnel body and a tunnel door. The ancillary equipment includes a car shelter, fire-fighting facilities, emergency communications, and drainage facilities. Long tunnels also have special ventilation and lighting equipment.

[0003] The quality inspection of the tunnel waterproof layer is usually carried out by using a crack detector with a probe pen attached to the inner side of the tunnel to complete the inspection, so as to ensure the integrity of the waterproof layer and whether it is deformed.

[0004] The utility model patent application with the announcement number CN218268366U discloses a tunnel waterproof layer construction quality inspection mechanism, including a mobile vehicle, a handrail extending to the outside of the mobile vehicle is fixedly installed on one end of the mobile vehicle, and a detection component is arranged on the mobile vehicle, and the detection component includes a battery pack fixedly installed at the bottom of the mobile vehicle, and a first electric push rod is fixedly installed on the top of the mobile vehicle, and the first electric push rod is electrically connected to the battery pack. The tunnel waterproof layer construction quality inspection mechanism performs extended inspection by setting a mobile vehicle, a first electric push rod, a mounting plate, a crack detector and a probe pen, thereby replacing the inconvenience of the original staff manually measuring with the help of a working platform, and further provides a sliding plate and a spring in a fixed cylinder, so that the contact effect between the probe pen and the tunnel is good, and a support plate, an extension rod, a second electric push rod and a push plate are provided, so that the mounting plate can obtain an additional extension height, thereby improving the practicality of the device.

At this time, the position to be detected will not be covered by impurities, and the detection work can be carried out. The detection data information is displayed on the display, so that the agglomerated impurities attached to the detection position can be crushed and cleaned before the detection work, so as to avoid the situation where impurities cover the detection position and affect the detection results, thereby improving the detection accuracy.

The quality monitoring device for tunnel construction described in the present invention uses a water pump to extract water from the water tank, and sprays the water into the tunnel through a hose and an atomizing nozzle, so as to reduce dust in the tunnel. At the same time, the first motor can be used to drive the atomizing nozzle to rotate to adjust the spraying angle, thereby reducing dust in the tunnel, which is more environmentally friendly.

[0019] The present invention can break and clean the agglomerated impurities attached to the detection position before the detection work, so as to avoid the situation that the impurities cover the detection position and affect the detection result, thereby improving the detection accuracy; the tunnel can be dust-reduced, which is more environmentally friendly.
