Abstract
The utility model relates to the technical field of tunnel construction, in particular to a maintainable drainage system used for a tunnel. The maintainable drainage system used for the tunnel comprises a tunnel side groove. Longitudinal drainage blind pipes which are distributed longitudinally and are connected in a subsection mode are arranged on the side wall of the tunnel, a plurality of circumferential drainage blind pipes which are distributed in parallel are arranged on an inverted arch of the tunnel, and each longitudinal drainage blind pipe and each circumferential drainage blind pipe are communicated with the tunnel side groove. The fact that the maintainable drainage system used for the tunnel is distributed along drainage blind grooves of the whole tunnel is more reasonable, and water-proof effect is improved. Due to the facts that the longitudinal drainage blind pipes and the circumferential drainage blind pipes are arranged in a subsection mode, and out-covering geotextile which is frequently-used is selected to be used for punching bellows, the maintainable drainage system used for the tunnel is good in water diversion and drainage performance, low in cost, convenient to disassemble and easier to maintain.
Description
Technical field
The utility model relates to tunnel construction technology field, particularly a kind of tunnel with safeguarding drainage system.
Background technology
Along with the fast development of modern railways, highway, especially in the mountain area, the tunnel, saves time back and forth between two places close to straight line, safer, become more and more common traffic ingredient.In the constructing tunnel process, tunnel drainage system is particularly important, is directly connected to the workmanship in tunnel, normally uses and safe operation.Tunnel drainage mainly is comprised of french drain and tunnel survey ditch at present, french drain is located on tunnel-side, french drain keeps at a certain distance away to be provided with gutter or to survey ditch with the tunnel and is connected, because french drain runs through whole tunnel, generally long, clear up more complicated when stopping up appears in french drain, and french drain is connected with tunnel survey ditch not sacrifices consisting of an ox, a sheep and a pig, easily leak when current are larger, change maintenance more difficult; Only contain in addition french drain and tunnel and survey the tunnel drainage system of ditch, tunnel invert does not have gutter to carry out diversion, draining, can't carry out effective draining to inverted arch.
The utility model content
Goal of the invention of the present utility model is: exist tunnel drainage system to carry out effective draining, problem difficult in maintenance to the tunnel for prior art, provide a kind of tunnel with safeguarding drainage system, this drainage system can effectively carry out draining, simple to operate, maintenance replacing convenience to the tunnel.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of tunnel is with safeguarding drainage system, comprise tunnel survey ditch, described tunnel-side be provided with along the tunnel vertically distribute, the longitudinal drainage blind pipe of connection segment, described tunnel invert is provided with the circle draining blind pipe of some sections parallel distributions, and every section described longitudinal drainage blind pipe, circle draining blind pipe all are communicated in described tunnel and survey ditch.
Preferably, every section longitudinal drainage blind pipe, circle draining blind pipe end is provided with bending part.
Preferably, adjacent two sections described longitudinal drainage blind pipes are spaced apart 8 ~ 10m.
Preferably, adjacent two sections described circle draining blind pipes are spaced apart 5 ~ 10m.
Preferably, described longitudinal drainage blind pipe, circle draining blind pipe are the punching bellows of outsourcing geotextiles.
Preferably, described circle draining blind pipe is connected in described tunnel invert surface by cement nail and narrow strip PE plate.
Preferably, described tunnel-side is provided with expansion bolt, and described longitudinal drainage blind pipe is fixed on described expansion bolt by clamp.
In sum, owing to having adopted technique scheme, the beneficial effects of the utility model are:
A kind of tunnel described in the utility model is with safeguarding drainage system, vertically distribute by being provided with on tunnel-side along the tunnel, the longitudinal drainage blind pipe of connection segment, be provided with the circle draining blind pipe of some sections parallel distributions at tunnel invert, every section longitudinal drainage blind pipe, circle draining blind pipe are provided with bending part and connect tunnel survey ditch, it is more reasonable that the weeper drain in whole tunnel distributes, and strengthened waterproof effect; Because longitudinal drainage blind pipe, circle draining blind pipe are subsection setup, and select outsourcing geotextiles punching bellows, this system has good water guide, drainage performance, and cost is lower, convenient disassembly, and maintenance is more prone to.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
As shown in Fig. 1-4, a kind of tunnel is with safeguarding drainage system, comprise tunnel survey ditch 2, described tunnel-side 1 be provided with along the tunnel vertically distribute, the longitudinal drainage blind pipe 3 of connection segment, described tunnel invert is provided with the circle draining blind pipe 4 of some sections parallel distributions, and every section described longitudinal drainage blind pipe 3, circle draining blind pipe 4 connect described tunnel and surveys ditch 2.
Wherein, every section longitudinal drainage blind pipe 3, circle draining blind pipe 4 ends are provided with bending part 5 and connect described tunnel and survey ditches 2, and circle draining blind pipe 5 adopts φ 50mm outsourcing geotextiles punching bellowss, and longitudinal drainage blind pipe 3 adopts φ 100 outsourcing geotextiles punching bellowss; Adjacent two sections circle draining blind pipes 4 arrange every 5～10m, and adjacent both ends longitudinal drainage blind pipe 3 arranges every 8～10m, and under the base area, steeping in water for reconstitution is educated the situation adjustment, and corner bevelling incoming tunnel lateral sulcus 2 is carried out in longitudinal drainage blind pipe 3 two ends and circle draining blind pipe 4 lower ends.
Carry out circle draining blind pipe 4 fixedly the time, its french drain position is undertaken by design in principle, but infiltration situation actual in the tunnel appropriately adjusts, pocket by the injection aspect and the place of EXIT POINT is arranged as far as possible, (be of a size of 8 * 20cm) and with cement steel nail, it followed closely in the tunnel invert surface, the steel nail spacing is made as 30～50cm to circle draining blind pipe 4 with PE plate fillet along the line.
Carry out again longitudinal drainage blind pipe 3 fixedly the time, its longitudinal drainage blind pipe 3 is pressed design code line so that the french drain position is accurately reasonable, the gradient that longitudinal drainage blind pipe 3 is installed is consistent with line slope; Adopt boring to locate, the locating hole spacing is at 30cm～50cm.Expansion bolt is squeezed into locating hole, encase longitudinal drainage blind pipe 3 with nonwoven, tie with tied silk, block longitudinal drainage blind pipe 3 with clamp, then be fixed on expansion bolt.
