Description
Technical field
This utility model relates to hydroelectric power plant, refers in particular to a kind of hydroelectric power plant dam observation device.
Background technology
Owing to dam is built in the fifties in last century, limited by Technical and economical level at that time, only devised the dam crest horizontal displacement of collimation line method observation dam at that time. To dam crest horizontal displacement observation facility be transformed by current specifications requirement, then there is following difficult point: first is from safety of dam body, difficulty of construction and cost, each monolith needing observation newly cannot be bored inverted vertical hole, adopt normal line method observation dam crest horizontal displacement. Second is affected by south weather owing to laser collimation in vacuum line method and atmospheric laser collimate method observation, and current successful example is less, and dam top trend is broken line type, and dam should not be adopted. Comprehensive analysis, intends adopting method of tension wire alignment that dam displacement monitoring is transformed. Due to the restriction by dam crest environmental condition; the design of original tension wire system is not good enough; steel wire protection sleeve pipe and each measuring point guard box of original tension wire system are all embedded under dam crest footpath; cannot ensure in measuring point guard box anhydrous time rainy for a long time; and artificial drainage workload is quite big, cannot ensure that tension wire is artificial completely and automated system properly functioning.
Summary of the invention
What this programme considered tension wire arranges impact dam facing is clean and tidy, attractive in appearance, and tension wire is placed in below footpath by this scheme, sets up new tension wire sleeve pipe to ensure Element of automatic control in wet condition properly functioning on original tension wire sleeve pipe.
For achieving the above object; technical scheme provided by the utility model is: a kind of hydroelectric power plant dam observation device; it includes the tension wire measuring box on the concrete pier being arranged on below footpath; it is provided with tensile-line instrument in tension wire measuring box; the tank wall of tension wire measuring box both sides is provided with seamless steel pipe; seamless steel pipe is set with tension wire protection pipe; tensile-line instrument top is provided with the tension side clamp groove of horizontal V-arrangement, and bracing wire body sequentially passes through tension wire protection pipe, seamless steel pipe extends in tension wire measuring box and is connected with tension side clamp groove.
Being provided with the base being made up of steel plate bottom described tension wire measuring box, tension wire measuring box bottom welding is on base, and the corner of base is provided with fixing threaded hole, and fixing threaded hole is fixed on concrete pier by corresponding expansion bolt.
Described tension wire protection pipe adopts coating steel pipe to make shaping.
This utility model has the features such as safe, applicable, has and well promotes and practical value, can produce good economic benefit and social benefit widely after popularization and application.
Accompanying drawing explanation
Fig. 1 is floor map of the present utility model.
Fig. 2 is cut-away view of the present utility model.
Detailed description of the invention
Below in conjunction with all accompanying drawings, the utility model is described in further detail, preferred embodiment of the present utility model is: referring to accompanying drawing 1 and accompanying drawing 2, hydroelectric power plant's dam observation device described in the present embodiment includes the tension wire measuring box 1 on the concrete pier 2 being arranged on below footpath, can also according to according to former tension wire observation station position, installing tension wire measuring box 1; Meanwhile, when end points, measuring point are buried underground need on concrete in advance joint bar, make the concrete pier of measuring point reflect the situation of this point completely; Being provided with tensile-line instrument 3 in tension wire measuring box 1, the tank wall of tension wire measuring box 1 both sides is provided with seamless steel pipe 4, and seamless steel pipe 4 is set with tension wire protection pipe 5, and tension wire protection pipe 5 adopts coating steel pipe to make shaping; Tensile-line instrument 3 top is provided with the tension side clamp groove 6 of horizontal V-arrangement, and the V-groove centrage of tension side clamp groove 6 is consistent with tension wire direction, and the horizontal elevation of V-groove should slightly above pulley top. Bracing wire body 7 sequentially passes through tension wire protection pipe 5, seamless steel pipe 4 extends in tension wire measuring box 1 and is connected with tension side clamp groove 6. Being provided with the base 8 being made up of steel plate bottom tension wire measuring box 1, tension wire measuring box 1 bottom welding is on base 8, and the corner of base 8 is provided with fixing threaded hole, and fixing threaded hole is fixed on concrete pier 2 by corresponding expansion bolt. The measuring point part of this programme is installed must be reliable, can accurately reflect the displacement of measuring point. And making measuring point as far as possible on same elevation, vertical error is within �� 5mm. Manpower comparing surveys matching requirements surveyors' staff must level and be perpendicular to tension wire direction. Measuring point, end points and wire body must have protection facility simultaneously. Protection pipe to be placed on support, adjacent two effective pipe collar or Flange joint, and measuring point protection to consider Radix Saposhnikoviae with being connected between pipeline.
The embodiment of the above is only the preferred embodiment of this utility model, not limits practical range of the present utility model with this, therefore all changes made according to the shape of this utility model, principle, all should be encompassed in protection domain of the present utility model.
