Embodiment:
Certain key water control project key construction is Concrete Face Rockfill Dam (crest elevation ▽ 410.0m, maximum height of dam 233m).
Vertical displacement observation is the big event of earth and rockfill dam safety monitoring, and being divided in dam dam body inside is three main monitoring sections, is respectively: horizontal 0+132.0m section, horizontal 0+212.0m section and horizontal 0+356.0m section.Five different elevations places at ▽ 235.0m elevation, ▽ 265.0m elevation, ▽ 300.0m elevation, ▽ 340.0m elevation and ▽ 371.0m elevation arrange 70 sedimentation measuring points altogether.Rockfill has been built 11 observation rooms 1 behind the dam, uses 5 pairs of sedimentation measuring points of water-pipe type settlement instrument to observe.
Water-pipe type settlement instrument needs equipment is replenished distilled water before observation, needs regularly to clean connecting pipeline simultaneously and carries out plant maintenance.Be necessary whole observation system is installed a cover automatic water supply system.
Whole automatic water supply system by preparation and retaining room 3, dam after aqueduct 2 and a plurality of observations room 1 form, in Fig. 3, tap water is made distilled water through distillation machine 12 and is stored in water storage box 9; Float valve 10 inlet end connect tap water water inlet pipe 11, water outlet end connects distillation machine 12 water inlet pipes, float valve 10 detects the water level of distilled water in the water storage box 9, the water inlet of control distillation machine, adopt the precision of float valve control not high, but good reliability, and the required precision to height of water level is not high in the native system, is reasonable selection so adopt float valve.Distillation machine has into water and controls function automatically, promptly when distillation machine water inlet back startup power work, quits work after cutting off the water supply.By the closed-loop control between water level-float valve-distillation machine, make the certain water yield of the automatic maintenance of distilled water in the water storage box 9.
In Fig. 2, aqueduct 2 is connected with the outlet of water storage box 9 behind the dam, by gravity with distilled water to observation room 1 in the equipment moisturizing.
The tubing of use is considered the requirement use PPR tubing of cleaning and can not be used coating steel pipe in the aqueduct 2 behind the dam, because dam crest to the ▽ 235.0m elevation observation station discrepancy in elevation reaches 175m, and the maximum working pressure of the PN2.0MPa that approaching civilian PPR tubing can reach.
Assault the calculation of pressure formula according to simple and easy water hammer:
Pwh＝PΔV/gc[P/gc(1/k+d/bE)]
-1/2
Pwh wherein: maximum assault pressure, P: liquid specific gravity, Δ V: change in flow, gc: gravity constant, K: liquid capacity modulus of elasticity, d: bore, b: pipe thickness, E: tubing matter bulk modulus.
Result of calculation shows the water hammer assault pressure superposition hydrostatic pressure that produces in the valve switch process, directly do not use the tubing connection can not satisfy safe requirement if add safeguard measure.
Adopting reducing valve and poppet valve to guarantee pipeline safety in this example, is the reducing valve 4 of 0.5Mpa at ▽ 310.0m elevation installation outlet pressure, and pipeline is divided into two sections from the centre, and the maximum hydrostatic pressure that each section bears is not more than 1.0 to 1.2MPa.Control water hammer pressure at ▽ 340.0m and the terminal poppet valve that 1.6MPa is installed of ▽ 235.0m elevation observation station pipeline, guarantee that tubing operates in the safe handling pressure limit.
Consider the dam site temperature temperature that may be below the freezing point in the winter time, the polyethylene foam thermal insulation casing is set outside water pipe, use the M7.5 mortar to bury, pipeline slope, road gesture on the way lays, and prevents the pipeline frost heaving failure.
Water supply tank 7 in the observation room 1 adopts stainless steel, and the top is provided with and partly renovates, and the side is provided with the water level observation tube, and the bottom is provided with atmospheric valve and overhauls.
System's operation control flow is seen Fig. 1, and figure hollow core arrow is represented distilled water, and solid arrow is represented control.
On dam water-pipe type settlement instrument 5, telemetering equipment has been installed, has been had the ability of real-time monitored.The instrument telemetering equipment is the master control of system's operation, when apparatus measures needs water, consumes the distilled water of storage in the water supply tank 7; Float valve is opened when the distilled water in the water supply tank 7 reduces to certain value, replenish by the water yield in the water storage box 9 in 2 consumption preparations of aqueduct behind the dam and retaining room 3, the water yield in the water storage box 9 is replenished automatically by the operation of the control of the float valve in it distillation machine.
Whole water system does not need manual intervention to move automatically; can give full play to the usefulness of telemetry system; when special operation conditions such as dam experience flood, earthquake, not can in time observe by the influence of meteorology, manpower factor; guarantee to obtain up-to-date safety monitoring data, for the dam safety operation provides decision-making foundation.
