Abstract
The invention relates to an in-tunnel prefabricated cable tube and a prefabricated water drainage pipe structure. In current tunnel engineering, the longitudinal cross-section of a water drainage ditch is commonly rectangular; a cable trough with a relatively small section area is formed in the outer side of the water drainage ditch; the water drainage ditch and the cable trough are made of concrete materials with relatively great dose, and cannot be flexibly changed when maintenance is needed once breakage happens. According to the invention, the prefabricated cable pipe and the prefabricated water drainage pipe are transversely arranged side by side at the inner side of a tunnel lining arch foot and the outer side of an inverted arch filling outer side; the outer side pipe wall of the prefabricated water drainage pipe is provided with a water drainage hole; a water guide tube is arranged in the tunnel surrounding rocks; the water guide tube is inserted into the water drainage hole; the diameter of the prefabricated water drainage pipe is greater than that of the prefabricated cable pipe; and the prefabricated water drainage pipe is positioned at the outer side of the prefabricated cable pipe. The conventional rectangular ditch cable trough is changed into a circular prefabricated pipe structure, and the manufacturing cost of the adopted fabricated pipe is obviously lower than the dose of concrete of the ditch cable trough, so that the cost is saved; and the prefabricated pipe is directly laid, so that the work of constructing ditch wall concrete, prefabricating a cover plate and the like is saved, and therefore, the construction is greatly convenient.
Description
Technical field
The present invention relates to a kind of novel cable and pass through tunnel and tunnel internal drainage structural system, be specifically related to prefabricated cable tube and prefabricated drain structure in a kind of tunnel.
Background technology
In existing tunnel engineering, tunnel drainage structure mainly uses the both sides inside tunnel-liner respectively to arrange the mode in a gutter, by the effect jointly such as splash guard, geotextiles, blind pipe, tunnel surrounding water is introduced gutter, outside discharge hole, it is provided with cable trough outside it, passes through tunnel for cabling.Longitudinal cross-section, gutter is the most rectangular, gutter and cable trough are concrete material, cover plate is armored concrete precast construction, large usage quantity, formwork erection difficulty during construction, difficulty of construction is relatively big, and progress is slow, take long in time limit, and ditch body is the most damaged, bottom of trench often produce ooze, disease of leaking, cover plate is prefabricated reinforced concrete, large usage quantity, occur breakage cannot exchange flexibly when needing repairing, owing to overall dimensions is relatively big, increase tunnel clearance section, cause investment waste, and occur breakage cannot exchange flexibly when needing repairing.
Summary of the invention
It is an object of the invention to provide prefabricated cable tube and prefabricated drain structure in a kind of tunnel, use drain pipe and cable tube, convenient construction and the later maintenance of prefabricated pipe form.
The technical solution adopted in the present invention is:
Prefabricated cable tube and prefabricated drain structure in tunnel, it is characterised in that:
Inside tunnel-liner arch springing, inverted arch fill be arranged side by side prefabricated cable tube and prefabricated drain pipe laterally outside, cross section is circle；
Outside prefabricated drain pipe, tube wall is provided with osculum, is provided with aqueduct in tunnel surrounding, and aqueduct inserts in osculum.
The caliber of prefabricated drain pipe is more than prefabricated cable tube, and prefabricated drain pipe is positioned at outside prefabricated cable tube.
Between inverted arch filling lateral ends and tunnel-liner arch springing, space, prefabricated cable tube and prefabricated drain pipe are set and are positioned at this space.
Prefabricated cable tube and prefabricated drain pipe are longitudinally made up of the splicing of more piece prefabricated tube coupling along tunnel, and joint is provided with inspection shaft.
The invention have the advantages that
1, the prefabricated pipe cost used is significantly lower than ditch cable trench concrete amount, cost-effective, reduces cost；
2, prefabricated pipe is directly laid, and eliminates the work such as construction furrow bank concrete, prefabricated cover plate, greatly facilitates construction, accelerating construction progress；
3, it is easy to check, change, the most easily finds that water outlet french drain is the most unimpeded, it is simple to maintenance, it is to avoid during operation, the phenomenons such as ditch results in blockage fallen into by cover plate；
4, the most antifreeze, pipe easily takes antifreezing measures, has superiority very much in severe cold area, it is to avoid ditch furrow bank breakage causes Common Diseases such as leaking, and cable tube fire protecting performance is good；
5, water pipe diameter can select flexibly according to water yield, exchange, and saves space, can reduce whole tunnel cross-section.
Accompanying drawing explanation
Fig. 1 is present configuration figure.
In figure, 1-inverted arch is filled, 2-prefabricated cable tube, the prefabricated drain pipe of 3-, 4-aqueduct.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the present invention will be described in detail.
Prefabricated cable tube and prefabricated drain structure in a kind of tunnel that the present invention relates to, inside tunnel-liner arch springing, inverted arch fills and 1 is arranged side by side prefabricated cable tube 2 and prefabricated drain pipe 3 laterally outside.Inverted arch is filled and is arranged space between 1 lateral ends and tunnel-liner arch springing, and prefabricated cable tube 2 and prefabricated drain pipe 3 are positioned at this space.The caliber of prefabricated drain pipe 3 is more than prefabricated cable tube 2, and prefabricated drain pipe 3 is positioned at outside prefabricated cable tube 2.Prefabricated drain pipe 3 caliber can be adjusted flexibly according to water yield, and the caliber of prefabricated cable tube 2 is adjusted flexibly according to the number of cables passed through tunnel.Outside prefabricated drain pipe 3, tube wall is provided with osculum, is provided with aqueduct 4 in tunnel surrounding, and aqueduct 4 inserts in osculum.
Prefabricated cable tube 2 and prefabricated drain pipe 3 are longitudinally made up of the splicing of more piece prefabricated tube coupling, and joint is provided with inspection shaft.
The present invention replaces traditional ditch cable trench set-up mode with small one and large one two concrete prefabricated pipes, and in terms of cost Control, difficulty of construction and later maintenance, the most relatively prior art has obvious advantage.
Present disclosure is not limited to cited by embodiment, and the conversion of any equivalence that technical solution of the present invention is taked by those of ordinary skill in the art by reading description of the invention, the claim being the present invention is contained.
