The primary support of the tunnel can adopt shotcrete support, and quick-hardening concrete is sprayed on the surface of surrounding rock of the tunnel by using a spraying machine to form a concrete lining layer with a certain thickness, so as to play a role in support. When the self-adhesive waterproof board is adopted to waterproof a tunnel, the primary support of the tunnel needs to be arranged firstly, and then the self-adhesive waterproof board is installed on the support surface.
S3, fixing the self-adhesive cloth 1 on an initial support in a tunnel through an automatic nail shooting device, and simultaneously laying a plurality of adhesive tapes 4 in parallel along a longitudinal reference line 3 on the surface of the waterproof board body 2;
In the step, the automatic nail shooting device is utilized to fix the self-adhesive cloth in a common fixing mode, so that the self-adhesive cloth is prevented from shifting, and compared with other fixing modes, the nail shooting device is free from other pretreatment, and is simple and convenient to operate. Specifically, the distance between the fixed points of the shooting nails is 50-60 cm, the maximum span of the side wall to the arching line is 60-80 cm, the maximum span of the side wall to the top surface of the cover plate is 80-100 cm, and the bottom is 100-150 cm.

Further, the width of the waterproof board body is 4m, the length is formulated according to the paving length, no joint is needed in the paving range, if the lap joint is unavoidable, the lap joint is carried out by adopting the upper part to lean against surrounding rock and the lower part to lean against the line side, the paving of the self-adhesive waterproof board needs to be moderate in tightness, and the artificial water storage point formed by tearing or loosening too tightly is avoided.
In some embodiments of the present invention, in step S4, in order to assist in determining whether the self-adhesive cloth 1 is precisely aligned with the reference line 3 of the waterproof board body 2, a first magnetic attraction member 5 is disposed at the intersection of the grid lines of the self-adhesive cloth 1, and a second magnetic attraction member 6 is disposed at the intersection of the grid lines of the waterproof board body 2, and these two sets of magnetic attraction members can be automatically attracted and positioned by magnetic force.
In the aligning process of step S4, if the first magnetic attraction member 5 and the second magnetic attraction member 6 are aligned and attracted together, it can be determined that the alignment of the self-adhesive cloth 1 and the reference line 3 of the waterproof board body 2 is accurate, and if not all the attraction is performed, it is indicated that the reference line 3 still has deviation and needs to be adjusted. By utilizing the attraction condition of the magnetic attraction piece, the alignment precision can be rapidly judged, and repeated trial and error adjustment is avoided. When misalignment is detected, the position of the waterproof board body 2 needs to be adjusted until the two groups of magnetic attraction pieces are attracted, so that the reference line 3 is ensured to be completely aligned.
In addition, for the inspector, after the waterproof board body is adhered to the self-adhesive cloth, the suction effect of the first magnetic suction piece 5 and the second magnetic suction piece 6 is detected, and the suction effect can be used as a feedback standard for the overall arrangement quality of the finished waterproof board, if the suction rate of the magnetic suction piece is very high, if the suction rate reaches more than 95%, the quality reaches the standard, and if the suction rate is low, the problem in the previous adhering process can be judged, and the overall quality is influenced.

In order to further improve the construction precision and efficiency of the tunnel self-adhesive waterproof board, an intelligent sensor is embedded between the first magnetic attraction piece 5 and the second magnetic attraction piece 6, the intelligent sensor can sense the contact pressure between the magnetic attraction pieces, the alignment state between the waterproof board body 2 and the self-adhesive cloth 1 can be detected and confirmed, alignment data can be sent to mobile equipment of constructors in real time through Bluetooth or Wi-Fi, the constructors are allowed to monitor the bonding state remotely under the condition of no physical contact, and a detailed lattice point bonding diagram can be generated on a screen of the mobile equipment or a remote controller. The graphical interface not only visually displays the alignment of each intersection, but also accurately marks any misplacement. In this way, a constructor can quickly identify and locate any improperly aligned parts, greatly reducing the time and effort of manual inspection. In addition, the data provided by the intelligent sensing system can be used for generating construction reports and quality control records, and detailed data support is provided for later quality inspection and maintenance. Through the intelligent alignment technology, the construction accuracy is improved, the whole working flow is optimized, and the installation of the tunnel self-adhesive waterproof board is more efficient and reliable.
