Abstract
The utility model relates to an apparatus used for automatically measuring the nonuniform settlement of civil engineering and other relative vertical displacements. The apparatus is used for calculating the foundational nonuniform settlement and relative vertical displacements via using the horizontal property of a liquid level through a set of communicating pipelines arranged on a building (or a structure) foundation according to the height marks of the liquid surface at different positions. The height marks of the liquid surface at measuring points can be directly read on site, and a resistor can be added near the liquid surface for long-distance monitoring through a circuit. The utility model having the advantages of convenient operation and high precision can be used for providing a favorable tool for monitoring the quality of a construction system for long.
Description
The utility model relates to the device of a kind of automatic measurement civil structure foundation uneven settlement and other vertical displacements, is applicable to the long-term monitoring automatically of architecture quality in the industries such as civil engineering work, communications and transportation, water conservancy.
Along with the expansion of state fundamental construction scale, buildings and structures quantity sharply increase.Buildings, structures kind that different request for utilizations makes large scale, high-quality require increase.To the monitoring and the research of building system safety of structure, permanance, become the important topic on building circle.The non-uniform settling on structural system basis can cause the distortion of structure stress, major accident such as can cause rupture, collapse when serious, so be the key factor that influences security of civil engineering work system and permanance.Measuring the classic method of non-uniform settling, is the position of measuring a plurality of reference point with spirit-leveling instrument, thereby calculates sedimentation.This method needs more manpower and bigger workload, can't realize robotization.For some special buildingss and structures (as bridge, underground and submerged structure, complex appearance buildings etc.), classic method is difficult to implement.
The purpose of this utility model is a kind of horizontality of utilizing liquid surface of design, be fixed in the structural pipeline that is interconnected by one group, automatically the device of Fundamentals of Measurement non-uniform settling and other relative vertical displacements provides strong instrument for observing foundation settlement chronically, easily.
The purpose of this utility model is achieved by the following technical solution: the vertical relative displacement self-operated measuring unit of structure that the utility model is made up of pick-up unit, signal processing circuit, computational analysis device etc., pick-up unit is constituted by a plurality of liquid level displays, communicating pipe reaching the resistance device of vertically laying at the liquid level place, the bottom of a plurality of liquid level displays was connected with communicating pipe, and the resistance device output of vertically laying in a plurality of liquid level displays connects signal processing circuit.
The utility model can also directly insert by the resistance device of the change in resistance that liquid surface lifting brought among the liquid level display, and an end of above-mentioned resistance device places under the liquid level, and the other end exposes liquid level, and its two ends are connected to the input end of signal processing circuit.A plurality of liquid level displays place respectively among separately the shell, and its place's shell is fixed on the basis or member of buildings or structures.The shell limit wall of a plurality of liquid level displays has with display window transparent, the band scale.
The utility model compared with prior art has simple in structure, and is easy to operate, the measuring accuracy advantages of higher.
Description of drawings of the present utility model is as follows:
Fig. 1 is a structural representation of the present utility model.
Elaborate below in conjunction with structure of the present utility model and using method.As shown in Figure 1, the utility model is by pick-up unit, signal processing circuit 14,15, the vertical relative displacement self-operated measuring unit of structure that computational analysis device 16 grades are formed, pick-up unit constitutes by a plurality of liquid level displays 6,7, communicating pipe 3,5 reaching 8,9 of the resistance devices of vertically laying at the liquid level place, the bottom of a plurality of liquid level displays 6,7 was connected with communicating pipe 3,5, and resistance device 8,9 outputs of vertically laying in a plurality of liquid level displays 6,7 connect signal processing circuit 14,15.Among resistance device 14, the 15 direct insertion liquid level displays 6,7 by the change in resistance that liquid surface lifting brought, an end of above-mentioned resistance device 8,9 places under the liquid level, and the other end exposes liquid level, and its two ends are connected to the input end of signal processing circuit 14,15.Among the shell that a plurality of liquid level displays 6,7 place respectively separately, its place's shell is fixed on the basis or member of buildings or structures.The shell limit wall of a plurality of liquid level displays can be with display window transparent, the band scale.
The shell 1 and 2 of liquid level display firmly is fixed in the basis of structure or the A on the member, B two places.By 3 and 4 communicating pipes that constitute being fixed on 1 and 2 at two ends.In the bottom 3 of communicating pipe liquid 5 being housed, is air (or vacuum) in the top 4.The communicating pipe sealing is in case liquid evaporation.The position 6 that the two ends sectional dimension is bigger about communicating pipe and 7 is the liquid level display.When the basis at A, B two places took place property to sedimentation, the two ends liquid level changed with respect to the position of display, changed the relative settlement that can calculate A, B two places easily thus.
Liquid level can be obtained by following manner with respect to the magnitude signal that location of displays changes:
One on-the-spot directly observation.In this case, the limit wall of liquid level display is made by transparent material, and it is marked with scale.The testing staff directly reads the position of rule of two ends liquid level on the liquid level observer at the scene, calculates relative settlement.When adopting this method, the resistance wire 8 and 9 among the figure one, electrode 10,11,12 and 13, signal processing circuit 14 and 15 and device such as controlling computer 16 can save;
The observation of two long-distance remote controls.In such cases, employed liquid is conducting liquid.The vertical resistance wire of laying 8 and 9 are housed, resistance wire two ends extraction electrode 10,11,12 and 13 in the liquid level display 6 and 7.When liquid level was in certain altitude, the following resistance wire of liquid level partly was equivalent to short circuit.If add fixed voltage in two end electrodes, when liquid level changed, the resistance in the loop changed, and brought the variation of current value.The analog value input signal treatment circuit 14 and 15 of change in resistance quantizes, and numerical quantities is sent into the controlling computer 16 of far-end, can obtain the liquid level of monitored point, thereby judges the relative settlement at A, B two places.
Above-mentioned two kinds of observed patterns can suitably be selected according to the actual needs of engineering.
Foundation uneven settlement measurement mechanism described in this instructions may extend to three or three above check points and monitors simultaneously, promptly by prolonging communicating pipe, increasing liquid level display number, reaches the purpose that multiple spot is monitored simultaneously.
