Description

Underground tunnel drainage structure

Technical Field

The utility model relates to a road construction technical field specifically is underground tunnel drainage structures.

Background

Tunnels are buildings that are built underground or underwater or in mountains, and that are used for motor vehicles to travel by laying railways or constructing highways. Can be divided into three categories of mountain tunnels, underwater tunnels and urban tunnels according to the positions of the tunnel bodies. A tunnel traversing from a mountain or under a hill to shorten the distance and avoid a large slope is called a mountain tunnel; an underwater tunnel for crossing a river or channel and passing under a river or sea floor; urban tunnels are used to pass through the ground of a city to meet the requirement of a railway to pass through a large city. The most constructed tunnels in the three categories are mountain tunnels. The tunnel need build drainage structures when the construction, but current drainage structures drainage efficiency is low, causes the inside ponding of tunnel easily to influence the vehicle current, for solving above-mentioned problem, we provide secret tunnel drainage structures.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an underground tunnel drainage structures possesses the efficient advantage of drainage, has solved current drainage structures drainage inefficiency, causes the problem of the inside ponding of tunnel easily.

In order to achieve the above object, the utility model provides a following technical scheme: underground tunnel drainage structures, including ground, the gravel layer has been laid at the top on ground, the bed course has been laid at the top on gravel layer, the basic unit has been laid at the top of bed course, the surface course has been laid at the top of basic unit, the surface course is the pitch layer, the drainage canal has all been seted up to the both sides at ground top, the width of drainage canal is fifty centimetres, the apron has been laid at the top of drainage canal, the width of apron is fifty centimetres, and apron length is eighty centimetres, the apron is made by the concrete.

Preferably, a support body is built on the top of the ground.

Preferably, a plurality of through grooves are formed in the cover plate, and the number of the through grooves is five.

Preferably, the center of the surface layer is convex.

Compared with the prior art, the beneficial effects of the utility model are as follows:

the utility model discloses a setting of ground, gravel layer, bed course, basic unit, surface course, drainage canal and apron has solved current drainage structures drainage inefficiency, causes the problem of the inside ponding of tunnel easily, and this drainage structures can effectively improve drainage efficiency, and avoids the inside condition that appears ponding of tunnel to guaranteed that the vehicle is normally current and improved this drainage structures's practicality.

FIG. 2 is a top view of the present invention;

FIG. 3 is a top view of the partial structure of the present invention;

fig. 4 is a partially enlarged view of a portion a in fig. 1 according to the present invention.

In the figure: 1. a ground surface; 2. a sandstone layer; 3. a cushion layer; 4. a base layer; 5. a surface layer; 6. a drainage channel; 7. A cover plate; 8. a support body; 9. a through groove.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the underground tunnel drainage structure includes a ground 1, a gravel layer 2 is laid on the top of the ground 1, a cushion layer 3 is laid on the top of the gravel layer 2, a base layer 4 is laid on the top of the cushion layer 3, a surface layer 5 is laid on the top of the base layer 4, the surface layer 5 is an asphalt layer, drainage channels 6 are respectively arranged on two sides of the top of the ground 1, the drainage channels 6 are fifty centimeters in width, a cover plate 7 is laid on the top of the drainage channels 6, the cover plate 7 is fifty centimeters in width, the cover plate 7 is eighty centimeters in length, and the cover plate 7 is made of concrete.

Further, the supporting body 8 is built at the top of the ground 1, and the broken stones can be effectively prevented from collapsing by the aid of the supporting body 8.

Further, a plurality of through grooves 9 have been seted up to the inside of apron 7, and the quantity that leads to groove 9 is five, leads to groove 9 through setting up, can effectively make ponding flow in the inside of drainage canal 6.

Furthermore, the center of the surface layer 5 is protruded, and accumulated water can effectively flow to two sides by arranging the protrusion.

The working principle is as follows: when there is ponding tunnel inside, because 1 arch on ground, water can flow to both sides to through the cooperation of logical groove 9 flow in to the inside of ditch 6, can carry out because of the drainage to ponding.
