Detailed description of the invention

Below in conjunction with detailed description of the invention, the utility model is described in detail.

The utility model relate to a kind of can the waterproof and water drainage system of comprehensive maintenance tunneling drain, the ring direction drainpipe 1 of multiple tracks transverse direction is longitudinally set along tunnel inside tunnel just pneumatically placed concrete, in first pneumatically placed concrete, presets collection pipe access ring direction drainpipe 1; Bottom, ring direction drainpipe 1 both sides access longitudinal drainage pipe 2; Be embedded with longitudinal central row ditch 5 bottom tunnel center line, transverse drain 3 is set between longitudinal drainage pipe 2 and central row ditch 5.Both sides, tunnel inner road face are provided with longitudinal lateral drainage gutter 4, are provided with transverse drain 3 between lateral drainage gutter 4 and central row ditch 5.

Longitudinal drainage pipe 2 picks out inside secondary lining oblique longitudinal pipe maintenance pipe, end is longitudinal pipe manhole 6.Longitudinal drainage pipe 2 and the junction of transverse drain 3 pick out oblique transverse pipe and overhaul and manage inside secondary lining, and end is transverse pipe manhole 7.Longitudinal drainage pipe 2 and longitudinal pipe are overhauled pipe and are connected by tee junction.Longitudinal drainage pipe 2, transverse drain 3 and transverse pipe are overhauled pipe and are connected by four-way connection.On lateral drainage gutter 4, longitudinal separation is provided with multiple vertical lateral row ditch inspection-pit 8.On central row ditch 5, longitudinal separation is provided with multiple vertical central row ditch inspection-pit 9.

Structure work progress is:

1, after tunnel excavation, first shotcrete construction lining cutting, for leakage point or seepage point, arranges the diversion of 100-200cm collection pipe to ring direction drainpipe 1;

2, in lining cutting behind, lay longitudinal drainage pipe 2, the gradient is consistent with tunnel longitudinal gradient.Longitudinal drainage pipe 2 first half is the pvc pipe of band eyelet, is beneficial to the remittance of country rock water; Ring direction drainpipe 1 and longitudinal drainage pipe 2 all adopt threeway to connect, and lay geotextiles, splash guard, longitudinal drainage pipe 2 wraps up by splash guard.
