A four-pipe water tube type sedimentation instrument, which consists of a sedimentation probe and an observation device located in the observation room. The bottom of the sedimentation probe is connected to a ventilation pipe and a drain pipe leading to the observation room. The improvement lies in the domestic For the first time, two water inlet pipes are used. There are two vertical water cups with a fixed overflow height difference inside the sinker head. The observation device has two measuring pipes. One end of the two water inlet pipes is respectively connected to the two water cups in the sinker head. , and the other ends are respectively connected to the two measuring tubes of the observation device. When measuring, fill the two water inlet pipes with water, and when the difference in the liquid level in the two measuring pipes is equal to the overflow height difference of the water cup in the settlement side head, record the readings of the two water inlet pipes respectively, and then measure the water at this point. settlement. The settlement instrument has the function of self-calibration of the measured value, which helps the observers to have a correct judgment on the measured value, and avoids the phenomenon of misleading the analysis of the observation data caused by blindly reading the untrue measured value; and greatly shortens the measurement time and improves the Measure efficiency.

Description

Four tubular type water-pipe type settlement instruments
Technical field
The utility model relates to a kind of instrument and equipment of monitoring the displacement of earth and rockfill dam internal vertical, belongs to dam displacement monitoring instrument field.
Background technology
At present, the water-pipe type settlement instrument of monitoring earth and rockfill dam internal vertical displacement has adopted connecting pipe principle, is made up of sedimentation gauge head, nylon tube, observation device etc.And the sedimentation gauge head adopts substantially is three-tube type, and promptly the bottom of gauge head tube connects three nylon tubes, and wherein one be water inlet pipe, is connected with observing vertical glass tube cashier's office in a shop, and this pipe overflow elevation in gauge head is represented the elevation of this measuring point; One is drainpipe, makes the interior unnecessary water of gauge head be discharged to the observation room; Another root is a snorkel, to guarantee air pressure and the external atmosphere pressure balance in the gauge head.But, in use there are following problems in traditional three-tube type sedimentometer: one, measuring method requires the measurement of each measuring point must be through water-filling fully, exhaust, and the measured value that just can read this point behind after a while stable thinks that promptly the overflow elevation water level of measuring point and water level in the observation vertical glass tube cashier's office in a shop are same elevation, this method defective is different with on-way resistance of differing that are subjected to communicating pipe length, be difficult to accurate judgement and when reach stable, could determine after must waiting considerable time, and measured value can't carry out self-correcting, and observed efficiency is low; Its two, construction is buried process or non-uniform settling underground and water inlet pipe takes place when big easily is blocked or leaks, then this measuring point promptly lost efficacy, and can't continue monitoring, and the probability that this situation takes place in engineering is used is higher.
Summary of the invention
Technical problem to be solved in the utility model is, overcome the above-mentioned shortcoming of existing three-tube type sedimentometer, four tubular type water-pipe type settlement instruments, for the same elevation in water level place in the overflow elevation water level of accurately judging measuring point and the vertical glass tube of observing cashier's office in a shop provides the school to survey means, shorten the Measuring Time of water-pipe type settlement instrument, improve efficiency of measurement, make the many water inlet pipes independently of water-pipe type settlement instrument measuring point simultaneously, even wherein a velamen decreases, also can measure, but not only the effect of measuring point backup had been surveyed but also had been played in the school by three traditional survey formulas.
In order to solve above technical matters: the utility model provides a kind of four tubular type water-pipe type settlement instruments, composition comprises: the sedimentation gauge head, be positioned at observation the room observation device, sedimentation gauge head bottom is connected with snorkel and the drainpipe that leads to the observation room, it is characterized in that, comprise two water inlet pipes, described sedimentation gauge head inside has the vertical water tumbler that two overflow discrepancy in elevation are fixed value, described observation device has two measuring tubes, one end of two water inlet pipes is connected with two water tumblers in the sedimentation gauge head respectively, and an other end is connected with two measuring tubes of observation device respectively.
During measurement,, wait to observe when the liquid level difference of elevation in two measuring tubes on the observation device equates with the water tumbler overflow discrepancy in elevation in the sedimentation side head in the room, write down the reading value of two water inlet pipes respectively, can measure the settling amount of this point two water inlet pipe water-fillings.
The beneficial effects of the utility model are as follows: because four tubular type sedimentometer gauge heads have adopted double water inlet pipes, so possessed measured value self-correcting function, help the observation personnel that measured value is had right judgement, avoided blindly reading untrue measured value and phenomenon that Structural Observed data Analysis is misled; Simultaneously, when observation is measured in the room, as long as when the water level discrepancy in elevation of same group of two measuring tubes equates with the water tumbler overflow discrepancy in elevation, just can reading, needn't pass through very long wait, shortened Measuring Time so greatly, improved efficiency of measurement; In addition, the snorkel of this sedimentometer, drainpipe and two water inlet pipes have constituted four tubular structures, and this four tubular structure is that system has increased a standby water inlet pipe, in case when a water inlet pipe breaks down, another root water inlet pipe can substitute it and use, and guarantees the normal operation of system.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the utility model four tubular type water-pipe type settlement instrument structural representations.
Embodiment
Four tubular type water-pipe type settlement instruments of present embodiment as shown in Figure 1, its composition comprises: sedimentation gauge head 1, be positioned at the observation device in observation room 2, sedimentation gauge head 1 bottom is connected with snorkel 3 and the drainpipe 4 that leads to observation room 2, its improvements are, also include two water inlet pipes 5,6, sedimentation gauge head 1 inside has the vertical water tumbler 7 that two overflow discrepancy in elevation are fixed value (H), 8, observation device has two measuring tubes, two water inlet pipes 5, an end of 6 respectively with sedimentation gauge head 1 in two water tumblers 7,8 connect, an other end respectively with two measuring tubes 9 of observation device, 10 connect.In this example, diameter, wall thickness, material, the equal in length of two water inlet pipes 5,6.Among the figure, horizontal dotted line is represented waterline, and when stablizing, the discrepancy in elevation of two waterlines is H.
As shown in Figure 1, snorkel 3 and drainpipe 4 and two water inlet pipes 5,6 have constituted four tubular structures, and it places in the protection tube 11, has played protective action.
During measurement, simultaneously to two water inlet pipe water-fillings, wait to observe when the liquid level difference of elevation in two measuring tubes on the observation device arrives H in the room, illustrate that then the overflow elevation water level of measuring point and the water level in the observation vertical glass tube cashier's office in a shop are same elevation, write down the reading value of two water inlet pipes respectively, can measure the settling amount of this point.
