Construction method used for tunnel road surface water seepage governance

Abstract

The invention relates to the field of road surface water seepage governance and discloses a construction method used for tunnel road surface water seepage governance. According to the disclosed construction method used for tunnel road surface water seepage governance, guiding drainage is performed by adopting an angle steel hole forming method, according to specific construction steps, a water outflow point and a water seepage range are looked over and determined; groove cutting is performed; a trapezoidal groove is formed; groove forming treatment is performed, and the trapezoidal groove is made to communicate with a water draining ditch; angle steel is arranged in the trapezoidal groove; filling of a gravel layer is performed; and road surface layer sealing is performed. According to theconstruction method, the angle steel is adopted for drainage, and the angle steel is firm in material, and not prone to damage due to vibration caused by a vehicle; expanding bolts are fixed to the two sides of the angle steel, but not the top of the angle steel in order to avoid that concrete damage is caused by the fact that construction is not proper, the angle steel is vibrated and bounces out, tires of passing vehicles are punctured, and accidents are caused; and the positions around the angle steel are filled with the gravel layer in order to prevent that due to the fact that the wateramount is too large or due to other factors, water flow reversely seeps, and discharging into the water draining ditch in time through a hole gap of the gravel layer can be achieved.

Description

technical field [0001] The invention relates to the field of pavement water seepage control, in particular to a construction method for tunnel pavement water seepage control. Background technique [0002] Tunnel water damage refers to the disturbance and harm of water encountered during the construction or operation of tunnels. Tunnel water damage during construction mainly refers to the damage caused by the groundwater or part of the surface water in the surrounding rock of the tunnel entering the tunnel in the form of leakage or gushing. [0003] For water seepage and water leakage in tunnels in operation, the lining of the tunnel will be damaged, the steel materials used to build the tunnel will also be corroded, some communication, lighting and other infrastructure of the tunnel will also be damaged, and the stability of the tunnel line will be damaged. Sexuality will have a serious impact, reducing the traction of the vehicle, and in severe cases, driving will be inter...

Problems solved by technology

[0003] For water seepage and water leakage in tunnels in operation, the lining of the tunnel will be damaged, the steel materials used to build the tunnel will also be corroded, some communication, lighting and other infrastructure of the tunnel will also be damaged, and the stability of the tunnel line will be damaged. Sexuality will have a serious impact, reducing the traction of the vehicle, and in severe cases, driving will be interrupted, which will seriously affect the safe operation of traffic and reduce the service life of the tunnel.

[0004] Using the traditional notch method to control water seepage is more effective for areas with clear seepage points, but the notch method is not effective in solving large-scale seepage due to the limited drainage area, and the pavement notch will affect the overall appearance and driving comfort. There are many deficiencies
