Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Underground conservation pool in tunnel, comprise inverted arch 5, inverted arch packed layer 51, supercrust 42, central inlet pipe 1 and central drain 31, described inverted arch 5 cross section is the arc of upper opening, described inverted arch packed layer 51 is arranged in the arc of inverted arch 5, described supercrust 42 is arranged on above inverted arch packed layer 51, described central inlet pipe 1 and central drain 31 are all arranged on below supercrust 42, described central inlet pipe 1 is arranged in inverted arch packed layer 51, water storage space 3 and grit chamber 2 is also offered in described inverted arch packed layer 51, described central inlet pipe 1, grit chamber 2, water storage space 3 and central drain 31 sequential communication, be provided with sand stop wall 21 between described grit chamber 2 and water storage space 3, between water storage space 3 and central drain 31, be provided with valve 32, lower than bottom water storage space 3 bottom described central drain 31, also comprise bleed off pipe 34, described bleed off pipe 34 one end is communicated with water storage space 3 top, and bleed off pipe 34 other end is communicated with central drain 31.
As shown in Figures 1 to 3, the effect of inverted arch packed layer 51 is the arc spaces filling and leading up inverted arch 5, and inverted arch packed layer 51 is provided with supercrust 42 above, and Pedestrians and vehicles can pass through on supercrust 42.The central inlet pipe 1 of this reservoir, grit chamber 2, water storage space 3 and central drain 31 are sequential communication, and central inlet pipe 1, grit chamber 2, water storage space 3 are all be arranged in the inverted arch packed layer 51 of underground in tunnel, and central drain 31 can according to circumstances be arranged in inverted arch packed layer 51, or be arranged on darker place.
As shown in Figure 4, when the muddy water containing a large amount of silt flows to grit chamber 2 from central water inlet pipe 1, due to the existence of sand stop wall 21, oarse-grained rubble silt sedimentation can fall into grit chamber 2; As shown in Figure 5, along with grit chamber 2 middle water level rises, current overflow from sand stop wall 21 and enter water storage space 3, and in water inlet, oarse-grained silt still can by sand stop wall 21 barrier deposition bottom grit chamber 2, and comparatively clean water enters water storage space 3; As shown in Figure 6, Open valve 32, then the water in water storage space 3 can flow into follow-up central drain 31 moment in a large number, thus realizes strong flushing effect to central drain 31, takes away the silt foreign material etc. in pipeline, makes it unobstructed.
Obvious, water stream channel between water storage space 3 and central drain 31 more spacious smooth-going being conducive to reduces streaming potential loss, developing result is better, so preferred, water storage space 3 and central drain 31 can adopt ramp 33 to be communicated with, and can be arranged on the position bottom lower than water storage space 3 bottom central drain 31, are namely to allow water storage space 3 and central drain 31 have certain altitude drop, current can be taken advantage of a situation and under, strengthen the scouring effect to central drain 31.
On the other hand, when not needing to rinse downstream central drain 31, after the water storage in water storage space 3 reach a certain height, central drain 31 can be flowed into along the bleed off pipe 34 shown in Fig. 3.
The effect of described sand stop wall 21 is that stoping silt to follow current enters water storage space 3, preferably, can be described sand stop wall 21 top higher than bottom central inlet pipe 1, be so more conducive to most of silt barrier deposition in grit chamber 2.
In order to increase the gross reservoir capacity of this underground conservation pool, preferably, can also be in described inverted arch packed layer 51, offer at least one secondary storage chamber 39, intercommunication pipe 391 is also provided with between described secondary storage chamber 39 and water storage space 3, described intercommunication pipe 391 one end is communicated with the lowest part of secondary storage chamber 39, intercommunication pipe 391 other end is communicated with water storage space 3, and intercommunication pipe 391 auxiliary connection storage chamber 39 one end is higher than the one end connecting water storage space 3.
After secondary storage chamber 39 is communicated with by intercommunication pipe 391 with water storage space 3, the water of water storage space 3 can flow in secondary storage chamber 39, so increase gross reservoir capacity, when Open valve 32 discharges water, the water in secondary storage chamber 39 can flow back to again water storage space 3 and flow in center water outlet pipe 31 again.As shown in Figure 1 in embodiment, the lowest part of secondary storage chamber 39 is communicated with by intercommunication pipe 391 with the lowest part of water storage space 3.
For the ease of removing the silt of deposition in grit chamber 2, can offer in the appropriate location of underground conservation pool and observe the facility such as well or access hole, preferably, can be that described inverted arch packed layer 51 also offers desanding raceway groove, described desanding raceway groove one end is communicated with grit chamber 2, and the desanding raceway groove other end leads to the ground in tunnel.Workman or machinery can be cleared up from desanding raceway groove grit chamber 2.
Described water storage space 3 can be that employing is cast-in-place, the prior art such as brick is built and is formed, can be preferably, described water storage space 3 is the box culvert structure of steel concrete, bottom box culvert and side is equipped with splash guard, box culvert inwall is coated with bituminous waterproofing material, and the seam crossing between box culvert and box culvert is embedded with waterstop and water expandable waterstop.
The box culvert structure of steel concrete can ensure that water storage space 3 top has sufficient intensity, meets vehicle pass-through in tunnel.Splash guard, the components such as waterproof material sealing rod can prevent reservoir from revealing.
Further, can also arrange pumping conduit 6, water storage space 3 lowest part is stretched in described pumping conduit 6 lower end, and pumping conduit 6 upper end is exposed from supercrust 42 top, and described pumping conduit 6 is also provided with water pump 61.The water extracted by pumping conduit 6 may be used for construction water or water for fire fighting etc.
