Abstract

The invention relates to a drainage tunnel for ditch water treatment and a maintaining method. The drainage tunnel for ditch water treatment comprises a tunnel body; a partition wall is arranged at the bottom of the tunnel body in the length direction of the tunnel body, so that the tunnel body forms two water via channels; a lock chamber is disposed at an inlet of the tunnel body; two gates are disposed in the lock chamber; the gates are in one-to-one correspondence with the water via channels. According to the maintaining method for the drainage tunnel, the drainage tunnel is adopted; maintaining is performed when the flow is small in the dry season; during maintaining, one gate on one maintaining side descends, water flows from the other side of the partition wall; after the maintaining of the former side is finished, the gate of the former side is lifted up, and the other gate on the other side descends so as to perform maintaining of the other side of the partition wall in the drainage tunnel. According to the drainage tunnel for ditch water treatment and the maintaining method, maintaining can be conveniently performed; a single tunnel structure is adopted; the construction cost is low; implementation is easy; the method is particularly suitable for ditch water treatment drainage tunnel with long-time overflowing and large flow difference of the dry season and the flood season.

Description

For water discharge tunnel and the repair method of ditch water treatment
Technical field
The present invention relates to a kind of water discharge tunnel for ditch water treatment and repair method, be particularly useful for long-term overcurrent, the larger ditch water treatment water discharge tunnel of flow difference in withered flood season phase.
Background technology
When high-mountain gorge areas builds building, a large amount of wastes is had to need to deposit, at high-mountain gorge areas, generally need to leave on small-sized river course or raceway groove, and occupied river course or raceway groove generally have current to pass through, therefore, need when depositing waste to carry out ditch water treatment.General ditch-water process comprises checkdam and water discharge tunnel, and checkdam did not generally allow water, and meanwhile, checkdam reservoir area generally only has water discharge tunnel as the unique passage of sluicing, and therefore, water discharge tunnel needs long-term overcurrent.On mountain channel or raceway groove, bed load is enriched, and can produce wearing and tearing to barrel structure when it enters water discharge tunnel, serious generation destroys.
In current ditch water treatment, many employing layouts drainage tunnel, does not consider maintenance condition; Or enrich for bed load, river course that flow is larger adopts layout two drainage tunnels, wheel flows through water maintenance.For permanent ditch water treatment water discharge tunnel, if do not consider maintenance, once water discharge tunnel destroys, current will cover checkdam, slag field of destroying by rush of water, and consequence is serious; And adopting two water discharge tunnel wheels to flow through water maintenance, then cost is high, uneconomical.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of convenient maintenance and the low water discharge tunnel for ditch water treatment of cost.
For solving the problems of the technologies described above the technical solution adopted in the present invention be: for the water discharge tunnel of ditch water treatment, comprise tunnel body, the bottom of tunnel body is provided with partition wall along tunnel body length direction, make tunnel body form two and cross aquaporin, the import of tunnel body is provided with lock chamber, be provided with twice gate in lock chamber, gate is with aquaporin is corresponding one by one excessively.
Further: partition wall is vertically installed in the center position of tunnel body bottom portion.
Further: this body section of tunnel is circular arch stalk bottom roundings gateway opening type.
Further: tunnel inner body wall and partition wall external surface are equipped with wearing course.
Further: the base slope of tunnel body is set to abrupt slope.
Further: on the length direction of tunnel body, the height of partition wall tapers off trend from front to back.
Further: twice gate is interlaced arrangement shape on lock chamber length direction.
Correspondingly, the present invention also provides a kind of repair method of water discharge tunnel, and adopt the water discharge tunnel that the invention described above provides, the normal overcurrent of water discharge tunnel in flood season, overhauls when water flow in dry season is less; During maintenance, the first gate of lower maintenance side, current, from partition wall other side overcurrent, after treating the maintenance of this side, then are mentioned this side gate, a lower other side gate, are carried out the maintenance of the other side of water discharge tunnel mid-board.
The invention has the beneficial effects as follows: the present invention can more easily overhaul, and adopt single tunnel junction structure, cost is low, easy to implement, is particularly useful for long-term overcurrent, the larger ditch water treatment water discharge tunnel of flow difference in withered flood season phase.

Mark in figure: 1-tunnel body, 2-partition wall, 3-lock chamber, 4-gate.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in FIG. 1 to 3, the present invention includes tunnel body 1, the bottom of tunnel body 1 is provided with partition wall 2 along tunnel body 1 length direction, make tunnel body 1 form two and cross aquaporin, the import of tunnel body 1 is provided with lock chamber 3, be provided with twice gate 4 in lock chamber 3, gate 4 is with aquaporin is corresponding one by one excessively.
Preferably, partition wall 2 is vertically installed in the center position bottom tunnel body 1, makes two flows crossing aquaporin identical, more reasonable structure.And partition wall 2 height can be determined according to water flow in dry season, partition wall 2 side should be made to meet overcurrent requirement in dry season.
Preferably, tunnel body 1 section is circular arch stalk bottom roundings gateway opening type, and structure is simple, be easy to construction, and flow condition is better.
Preferably, tunnel body 1 inwall and partition wall 2 external surface are equipped with wearing course, can improve application life.
Preferably, the base slope of tunnel body 1 is set to abrupt slope, makes tunnel water surface curve be b 2type dropdown curve, reduces flow section.In the art, abrupt slope is the tunnel base slope that gradient is greater than the critical slope of current under design discharge.
Preferably, on the length direction of tunnel body 1, the height of partition wall 2 tapers off trend from front to back.In tunnel running, water surface curve reduces from front to back gradually, and therefore, barrel partition wall height can reduce along with water surface curve and reduce.Partition wall 2 is too high will increase construction investment, can reduce flow section in flood season simultaneously.
Preferably, as shown in Figure 4, twice gate 4 is interlaced arrangement shape on lock chamber 3 length direction.If twice gate 4 is arranged in parallel, partition wall 2 thinner thickness at this position, affects partition wall 2 intensity, in order to not affect partition wall 2 intensity, then can only increase partition wall 2 thickness.Adopt the mode of interlaced arrangement, then need not increase partition wall 2 thickness, can investment reduction.
And for the repair method of water discharge tunnel, adopt water discharge tunnel provided by the invention, the normal overcurrent of water discharge tunnel in flood season, overhaul when water flow in dry season is less; During maintenance, the first gate 4 of lower maintenance side, current, from partition wall 2 side overcurrent in addition, after treating the maintenance of this side, then mention this side gate 4, a lower other side gate 4, carry out the maintenance of the other side of water discharge tunnel mid-board 2.
The present invention can more easily overhaul, and adopts single tunnel junction structure, and cost is low, easy to implement, is particularly useful for long-term overcurrent, the larger ditch water treatment water discharge tunnel of flow difference in withered flood season phase.
