Utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies of the prior art and provide a kind of tunnel drainage device,
It is discharged the water inside sump using the pattern that rectangle ditch, diversion drill by setting sump charge for remittance, and it is permanent to be able to satisfy
Administer the requirement of karst water.
In order to solve the above technical problems, the utility model proposes technical solution are as follows: a kind of tunnel drainage device is included in
Several being arranged at tunnel internal Karst water bursting mouth are interconnected and are used for the sump and rectangle ditch of charge for remittance, the rectangle ditch
One end is connected to the borehole wall of one of sump, and the other end is connected to tunnel Central drain, and the bottom of the sump is equipped with
The lower section of several diversions drilling, sump is equipped with scupper, and the diversion drilling is connected to scupper；The bottom of the sump
Portion is lower than the height of water burst mouth；The top of water burst mouth is arranged in the rectangle ditch.
As a further improvement of the above technical scheme: the well lid absolute altitude of the sump is flushed with tunnel road surface, is catchmented
Well is poured using armored concrete.
Further, the underface in the region of several sumps formation is arranged in the scupper.
Further, the quantity of the sump is four, and four sumps form rectangular configuration or square structure, sump
Quantity be mainly arranged according to issue, being set as four mouthfuls of The Small Wells mainly can be laid with two cover plates, the lid bigger than one piece
Plate is more advantageous to traffic safety.
Further, the quantity that diversion drills in each sump is 3-6.
Further, the quantity of the rectangle ditch is identical as the quantity of sump, or less than the quantity of sump, one is catchmented
Well is used with a rectangle ditch is unified.
The water discharge method of above-mentioned tunnel drainage device are as follows:
S1: digging several sumps at the Karst water bursting mouth in tunnel, the shaft bottom of sump is lower than water burst mouth；
S2: the aperture on the wherein borehole wall of one or several sumps opens up rectangle ditch, the end of rectangle ditch along this aperture
It is connected to tunnel Central drain；
S3: scupper is opened up at the following distance of sump；
S4: it is drilled with several diversions drilling in the bottom of each sump, the end of diversion drilling is connected to scupper.
As a further improvement of the above technical scheme: in the step S1 each sump be all made of armored concrete into
Row pours.
Further, diversion drilling is connected to scupper straight down in the step S4.
Compared with the prior art, the advantages of the utility model are:
1, the sump of the utility model can concentrate karst water and converge, and concentrate discharge；
2, the rectangle ditch of the utility model is connected to tunnel Central drain, makes full use of the Central drain row that tunnel is existing
Water；
3, scupper is arranged in the utility model below sump, and drills in bottom setting diversion of catchmenting, with draining
Hole communicates, and strengthens the discharge of karst water, and the quantity and size of diversion drilling can be depending on the size of water yield；
4, it is provided with well lid on the sump of the utility model, and is flushed with tunnel road surface, do not influence to run and facilitates inspection
It repairs.
