That is, when hanging geotextile lining, workers use measuring points, manually marking lines, and measuring the spacing between washers. The problems are: first, the accuracy of the spacing between washers controlled by workers is not high when hanging geotextile; second, there is arbitrariness in the operation of this method, which makes it difficult to control the spacing of the hot-melt washers of the hung geotextile, the size is uneven, and the accuracy is poor; third, it leads to delays in construction progress, low work efficiency, and affects construction quality. Utility Model Content

[0003] In order to overcome the shortcomings of the above-mentioned prior art, the utility model provides an adjustable positioning device for tunnel secondary lining waterproof hot-melt washers, which can effectively control the spacing of geotextile hot-melt washers during the construction process of hanging geotextile, improve the accuracy of the spacing of hot-melt washers, and thus improve the quality of geotextile hanging.

[0004] The purpose of the utility model is achieved through the following scheme:

[0005] A tunnel secondary lining waterproof hot-melt gasket adjustable positioning device, composed of a device body, the device body includes a diamond-shaped frame composed of four support rods, the four end corners of the diamond-shaped frame are respectively provided with arc-shaped bayonet openings facing outwards, the top ends of every two corresponding arc portions of the arc-shaped bayonet are respectively connected to each other with connecting rods, and the middle of the connecting rod is provided with a handle.

[0006] The support rod is composed of a plug-in outer sleeve and an inner rod structure. A fastener is arranged at the pipe end of the outer sleeve, and a scale is arranged on the rod body of the inner rod.

[0007] The connecting rod is composed of a plug-in outer sleeve and an inner rod structure. A fastener is arranged at the pipe end of the outer sleeve, and a scale is arranged on the rod body of the inner rod.

[0008] The curvature of the arc-shaped bayonet matches the radius of the hot-melt gasket.

[0009] The device body is made of steel material.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. The diamond-shaped frame of the utility model is made according to the designed spacing of the hot-melt gaskets. The support rods and connecting rods adopt a plug-in structure, and their width and length can be adjusted at will. The setting of the scale makes it more effective to improve the accuracy of the gasket spacing, reducing the phenomenon of uneven spacing of the geotextile hot-melt gaskets due to random operation of workers, so that the waterproof board is evenly stressed and the construction quality of the secondary lining is improved.

[0012] 2. This device can position the hot-melt gasket at one time, solving the cumbersome operation procedures of manually marking lines and measuring spacing with a ruler in the prior art. One or two people can operate the positioning device at one time, which can reduce the number of construction workers and improve construction efficiency.

[0013] 3. The utility model is easy to manufacture and can be processed using leftover steel bars, which is low in cost and reduces material waste and can be recycled. BRIEF DESCRIPTION OF THE DRAWINGS
