Description
Technical field
The utility model is related to groundwater velocity test device in a kind of Tunnel shaping latter tunnel surrounding.
Background technology
It is directed in recent years in constructing tunnel and proposes harnessing the river for " stifled row combining, based on stifled, limited drainage, environmental protection "
Theory, for the requirement of the groundwater resources and environment on protection path periphery, it is impossible to take under conditions of " based on row ", take
During the principle of " based on stifled, limited drainage ", the design to Tunnel Engineering bound pair tunnel water handling proposes new problem.It is substantial amounts of
Engineering practice shows, after tunnel excavation support, and groundwater occurrence there occurs huge change, crevice water, the pore water of country rock surrounding
Etc. hiding aquaporin as the deformation of country rock itself and the corrosion of water start redistribution.At present, the country lacks a kind of length
Phase feasible measure determines country rock groundwater velocity situation, and data supporting is provided for dynamic design parameter adjustment.
The content of the invention
For above-mentioned weak point of the prior art, the utility model offer one kind is simple in construction, can effectively survey
Try groundwater velocity test device in the tunnel surrounding of tunnel-liner behind surrounding groundwater velocity.
To achieve these goals, the utility model provides following technical scheme：Groundwater velocity in a kind of tunnel surrounding
Test device, including plate base and it is close to be arranged on flow velocity display, current meter, the water check valve on steel floral tube, the steel
Floral tube one end is provided with some force rods therewith at grade through base middle part on the base outer, described
Force rod is placed equidistant, and anchor pole normal thereto, the flow velocity display, current meter, sealing are provided with the force rod
Valve is located at base both sides respectively with anchor pole.
Preferably, the base includes the first billet, the second billet and the rubber being closely set between them
Backing plate.
Preferably, the base is square, force rod is provided with the middle part of four sides of base.
Preferably, the flow velocity display, current meter, water check valve are successively set on steel floral tube, water check valve is arranged at
Spray of molten steel tube end.
Preferably, second billet is located between the first billet and current meter.
The utility model can be seen that by above technical scheme simple in construction, the tunnel-liner back of the body can be effectively tested
Surrounding groundwater velocity, and then provide support for tunnel double-lining dynamic design parameter afterwards, effect is good, and the low suitable popularization of cost should
With.

Fast test device, when in use, steel floral tube 1 collect country rock surrounding underground water, and the system that force rod 6 and anchor pole 7 are constituted makes device
It can fix and point position, country rock periphery water flow velocity is tested through current meter and shown by flow velocity display 4, obtain related ginseng
Number, effect is good, cost is low, suitable popularization and application.
The technical scheme that the utility model example is provided is described in detail above, it is used herein specifically individual
Example is set forth to the principle and embodiment of the utility model example, and the explanation of above example is only applicable to help and understood
The principle of the utility model embodiment；Simultaneously for those of ordinary skill in the art, according to the utility model example, in tool
It will change in body embodiment and application, in summary, this specification content should not be construed as to this reality
With new limitation.
