Or the hint device of indication or element must have specific orientation, with specific azimuth configuration and operation, be not therefore understood that
It is to restriction of the present utility model.Additionally, term " first ", " second ", " the 3rd " are only used for describing purpose, and it is not intended that
Instruction or hint relative importance.
In description of the present utility model, it should be noted that unless otherwise clearly defined and limited, term " phase
Even ", " connection " should be interpreted broadly, for example, it may be being fixedly connected or being detachably connected, or is integrally connected；Can
To be to be mechanically connected or electrical connection；Can be to be joined directly together it is also possible to be indirectly connected to by intermediary.For this
For the those of ordinary skill in field, concrete meaning in this utility model for the above-mentioned term can be understood with concrete condition.
Refer to Fig. 1, the tunnel drainage blind pipe of the present embodiment, the top half of tube wall is provided with into water along pipe shaft total length
Hole.Further as can be known from Fig. 2, the cross-sectional area of described inlet opening is gradually increased from outside to inside, namely inlet opening is expanded for loudspeaker
The form in hole.
Wherein, " from outside to inside " refers to towards on the direction of close described tunnel drainage blind pipe central axis, namely away from
Close to tunnel drainage blind pipe central axis is inner side, and apart from tunnel drainage blind pipe central axis remote be outside.
In the present embodiment, the impurity such as the grains of sand, soil can be avoided to enter into into water by arranging the inlet opening of this kind of form
There is blocking so that the grains of sand, soil etc. can enter in draining blind pipe with infiltration and finally discharge, thus ensureing after hole
The drainage effect of drainage system.
In the present embodiment, inlet opening is preferably centrosymmetric structure, for example round table-like, billiard table shape, prism-shaped etc..Refer to
Fig. 1, in the present embodiment inlet opening using round table-like form it should be appreciated that accompanying drawing do not constitute to water inlet pore structure limit
System.
Further, can smoothly discharge after entering tunnel drainage blind pipe to ensure the impurity such as the grains of sand, soil, towards
On the direction of described tunnel drainage blind pipe central axis, described inlet opening is towards the drainage direction of described tunnel drainage blind pipe
Opposite direction tilts.
Specifically, because the density ratio water of impurity is big, so impurity is typically directly vertical after entering tunnel drainage blind pipe
Sedimentation.And current then enter in tunnel drainage blind pipe along the incline direction of inlet opening, thus current obtain and tunnel drainage is blind
Manage initial flow rate in opposite direction so that current run to the upstream of impurity, and the impurity settling the most at last flushes out tunnel row
Water blind pipe.
Additionally, for the smooth discharge ensureing impurity, the medial wall of tube wall can also be correspondingly improved.Specifically,
On tube wall, along pipe shaft total length, the medial surface of described tube wall is inclined plane to the top half relative with described inlet opening, and described inclines
Inclined-plane tilts gradually downward along drainage direction.This inclined plane can play certain guiding function to the discharge of impurity, prevents
Impurity is deposited in tunnel drainage blind pipe and ultimately results in line clogging.Certainly it should be noted that in order to conformance with standard requires simultaneously
It is easy to manufacture, special adaptations are not done to the external shape of tunnel drainage blind pipe.
In order to ensure that tunnel drainage blind pipe can reduce groundwater pressure to the full extent, preferably inlet opening is in described tunnel
It is in that blossom type is distributed, please with further reference to Fig. 1 on draining blind pipe.Furthermore it is preferred that inlet opening is uniformly divided on tunnel drainage blind pipe
Cloth.And, inlet opening setting space, diameter are mated with draining blind pipe drainability.
In the present embodiment, tunnel drainage blind pipe is solid wall pipe, the winding pipe of inner wall smooth or the inwall light of inner wall smooth
Sliding double-wall corrugated pipe.Preferably, adopt solid wall pipe as a diameter of 50mm～120mm of tunnel drainage blind pipe；Work as tunnel drainage
Double-wall corrugated pipe is adopted during a diameter of 150mm～600mm of blind pipe.
The present embodiment also provides a kind of tunnel drainage system, including inspection shaft and tunnel drainage blind pipe, described tunnel drainage
Blind pipe connects with described inspection shaft, and described tunnel drainage blind pipe is above-mentioned tunnel drainage blind pipe.
In the present embodiment, between many described tunnel drainage blind pipes, and described tunnel drainage blind pipe and described inspection shaft
Between all can using three way cock connect.
Wherein, three way cock includes the first pipeline section, and the second pipeline section and that relatively described first pipeline section is symmetrical
Three pipeline sections.Once the second pipeline section or the 3rd pipeline section block, then common practice is to be dredged by the first pipeline section.But
It is in prior art, it is impossible to control its trend well, thus being likely to second after high pressure dredging shower nozzle inserts the first pipeline section
During pipeline section blocking, high pressure is dredged the final injection of shower nozzle and is put to being towards the 3rd pipeline section.In view of this, the present embodiment is first
It is provided with division board on the shaft section of pipeline section, and is provided with through hole on division board, thus division board is realizing high pressure is dredged
Shower nozzle does not interfere with the circulation of the water of three-port structure on the basis of guiding.
It is assumed that the first pipeline section is first end near one end of the second pipeline section (or the 3rd pipeline section) in the present embodiment, and another
One end is the second end.In order to effectively guide to high pressure dredging shower nozzle, then the second end of division board Edge Distance first pipeline section
Port must not be too far away, and is preferably isolated plate and extends directly into the second end port.Additionally, the of Edge Distance first pipeline section of division board
One end port nor too remote, and be preferably isolated plate and stretch out the first pipeline section and extend into the second pipeline section and the 3rd pipeline section
Intersection.Certainly, the setting of division board can not affect the connection between the second pipeline section and the 3rd pipeline section.
Embodiment of above is merely to illustrate this utility model, rather than to restriction of the present utility model.Although with reference to enforcement
Example has been described in detail to this utility model, it will be understood by those within the art that, to technology of the present utility model
Scheme carries out various combinations, modification or equivalent, without departure from the spirit and scope of technical solutions of the utility model, all should
Cover in the middle of right of the present utility model.
