Abstract
The discharge structure of the tunnel limited drainage that the utility model provides, comprise be interconnected and diameter not wait two gutters, wherein gutter A diameter is less than gutter B, the sealing of described gutter A one end, the sealed end of gutter A stretches into gutter B, also comprise spring, be connected bottom described spring and gutter A sealed end, the gate valve sheet mated with gutter A cross-sectional sizes is provided with at the movable end of described spring, position on gutter A between bottom and gate valve sheet is provided with multiple delivery port, and described gate valve sheet is slidably connected in gutter A by stopper.The utility model structure is simple, not only has the effect of appropriate draining, can also eliminate the calcareous crystallization (or suspension sediment) being bonded at drainage pipe inside dexterously, is suitable for applying.
Description
Technical field
The utility model relates to a kind of discharge structure, particularly a kind of discharge structure being applicable to tunnel, limestone area limited drainage.
Background technology
The building of tunnel can change surrounding enviroment and obtain lithic drainage, requires higher or limestone area, will design tunnel drainage for the ecosystem.If do not establish drainage pipe in tunnel, underground water can produce very large pressure to liner structure, need during design significantly to strengthen lining thickness, cost is caused to raise, simultaneously, the excessive discharge of underground water also can bring harmful effect to surrounding environment, and the calcareous crystallization (or suspension sediment) in addition in tunneling drain blocks gutter, produces serious influence to tunnel drainage effect.Tunnel is through limestone area, because of calcareous Crystallization Plugging gutter, long-term draining is obstructed very large on tunnel structure impact, constantly increase at tunnel outer hydraulic pressure, the supporting drag of tunnel support structure also increases thereupon, when after tunnel support structure cracking, tunnel there will be infiltration drainage in various degree, potential potential safety hazard is produced to the operation in tunnel, in order to reduce the calcareous Crystallization Plugging gutter in the tunneling drain of limestone area, at present, enough attention are not caused to tunneling drain Crystallization Plugging when tunneling both at home and abroad, the process of the Crystallization Plugging problem in later stage is reckoned without in tunnel construction, therefore, design one spends draining in right amount, and the tunnel drainage structure that can solve Crystallization Plugging problem when later stage tunnel is runed is necessary.
Summary of the invention
For above-mentioned weak point of the prior art, the utility model provides a kind of discharge structure that can solve the appropriate tunnel limited drainage of Crystallization Plugging problem, draining.
To achieve these goals, the utility model provides following technical scheme: the discharge structure of a kind of tunnel limited drainage, comprise be interconnected and diameter not wait two gutters, wherein gutter A diameter is less than gutter B, the sealing of described gutter A one end, the sealed end of gutter A stretches into gutter B, also comprise spring, be connected bottom described spring and gutter A sealed end, the gate valve sheet mated with gutter A cross-sectional sizes is provided with at the movable end of described spring, position on gutter A between bottom and gate valve sheet is provided with multiple delivery port, described gate valve sheet is slidably connected in gutter A by stopper.
Can be found out by above technical scheme, the utility model structure is simple, when in gutter A, hydraulic pressure acquires a certain degree, hydraulic pressure will compress gate valve sheet, when gate valve sheet is depressed into after outfall, by the ponding of automatically discharging in catchment, after hydraulic pressure in gutter A reduces, spring will extend, spring drives gate valve sheet automatically will close delivery port, gutter A starts again to catchment, reach the effect of appropriate draining, the setting of stopper is in order to water plugging effect is better, the slidably reciprocating of stopper in addition, the calcareous crystallization (or suspension sediment) being bonded at drainage pipe inside can be cleared away dexterously, be suitable for applying.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
In accompanying drawing: 1-gutter A, 2-gutter B, 3-spring, 4-gate valve sheet, 5-delivery port, 6-stopper.
Detailed description of the invention
The utility model is further described below in conjunction with specific embodiment and accompanying drawing.
A kind of discharge structure of tunnel limited drainage as shown in Figure 1, comprise be interconnected and diameter not wait two gutters, wherein gutter A1 diameter is less than gutter B2, the sealing of described gutter A1 one end, the sealed end of gutter A1 stretches into gutter B2, also comprise spring 3, be connected bottom described spring 3 and gutter A1 sealed end, the gate valve sheet 4 mated with gutter A1 cross-sectional sizes is provided with at the movable end of described spring 3, position on gutter A1 between bottom and gate valve sheet is provided with multiple delivery port 5, described gate valve sheet 4 is slidably connected in gutter A1 by stopper 6.
When using on the spot, when in gutter A, hydraulic pressure acquires a certain degree, hydraulic pressure will compress gate valve sheet 4, when gate valve sheet 4 is depressed into after outfall 5, by the ponding of automatically discharging in catchment, after gutter A hydraulic pressure reduces, spring 3 will extend, spring 3 moves gate valve sheet 4 will close delivery port 5 automatically, gutter starts again to catchment, the effect of appropriate draining can be reached like this, the setting of stopper 6 is in order to water plugging effect is better, the contact area with gutter A1 inwall can be increased simultaneously, what prevent gate valve sheet 4 from bringing because of unbalance stress is crooked, whole discharge structure is caused normally to work, the slidably reciprocating of stopper 6 in addition, the calcareous crystallization (or suspension sediment) being bonded at gutter A1 inside can be cleared away dexterously, be suitable for applying.
Above the technical scheme that the utility model embodiment provides is described in detail, apply specific case herein to set forth the principle of the utility model embodiment and embodiment, the explanation of above embodiment is only applicable to the principle helping to understand the utility model embodiment; Meanwhile, for one of ordinary skill in the art, according to the utility model embodiment, detailed description of the invention and range of application all will change, and in sum, this description should not be construed as restriction of the present utility model.
