Description

Technical Field

[0001] The utility model relates to the technical field of tunnel construction, in particular to a tunnel vault construction density detection device. Background Art

[0002] The construction process of tunnel vaults is usually to build the initial support first, and then to carry out secondary lining on the inner surface of the initial support. A protective structure such as a waterproof board will be set between the initial support and the secondary lining layer. The secondary lining layer needs to be kept close to the initial support, but it can also exert excessive pressure on the initial support to avoid structural problems with the initial support. In the current construction method of tunnel vaults, the construction of the secondary lining layer often relies only on calculated data and experience. The density between the initial support and the secondary lining layer is difficult to control, that is, it is difficult to judge whether the concrete is poured densely, which will have an adverse effect on the construction quality.

After the construction of the initial support 31 of the vault is completed, the density detection device can adhere the base belt 10 to the bottom surface of the initial support 31 through the adhesive part 12. Later, during the construction of the secondary lining, the pressure sensor 11 on the base belt 10 can detect the pressure between the secondary lining layer 32 and the initial support 31 in real time, and transmit the detection result to the display terminal 20 through the transmission structure of the base belt 10.

[0025] The pressure sensor 11 is widely used, and the transmission structure of the baseband 10 can adopt common structures such as signal lines. These structures are well known to those skilled in the art and will not be described in detail here.

[0026] As a preferred embodiment of the utility model, it may also have the following additional technical features:

[0027] In this embodiment, the display terminal 20 has a plurality of display units 21 corresponding to each pressure sensor 11. Each display unit 21 is used to display the detection result of the corresponding pressure sensor 11, so that it is convenient to check the detection result of each pressure sensor 11, and it is convenient to locate the position of pressure discomfort, which is convenient for use. In this embodiment, each display unit 21 displays the pressure detection result through an indicator light. By setting the expected pressure value, when the pressure value is too large or too small, the corresponding display light is activated to display the detection result. The structure is simple and reliable, the cost is low, and it is easy to manufacture and use. In other embodiments, the display terminal 20 also uses other commonly used display structures such as a display screen.

[0028] In this embodiment, there are multiple adhesive portions 12 that are spaced apart along the length direction of the base tape 10 , which helps to improve the adhesion of the base tape 10 to the bottom surface of the arch initial support 31 .

[0030] In this embodiment, the outside of the base band 10 is covered with a waterproof layer, which can prevent external water vapor from entering the pressure sensor 11 and the transmission structure and causing failure and damage to the density detection device, making it more reliable.

[0031] In this embodiment, the base belt 10 is flexible, which is convenient for storage and for adapting to the bottom shape of the arch initial support 31 , and is convenient for use.

[0032] The display terminal 20 can be provided with a signal output unit to facilitate the transmission of the detection data of each pressure detector to other monitoring equipment, facilitate remote monitoring and multiple monitoring, and help to further ensure the construction quality. The signal output unit can adopt a wired transmission method such as a transmission connector, or a wireless transmission structure such as a wireless output unit.
