Embodiment
In conjunction with Fig. 1 and Fig. 2, a kind of template lining water-holding capacity proving installation comprises base 1, is arranged on the inner cylindrical tube 2 on the base, the top cover 4 that is arranged on the cylindrical column casing 3 on the base and can moves up and down.Above-mentioned inner cylindrical tube is positioned at the cylindrical column casing and is provided with the cylindrical column casing is concentric.Be furnished with the vertical spring 5 of even number root in the annular space between inner cylindrical tube and cylindrical column casing, vertical spring is at least one group, in each group two vertical springs that are symmetric arrangement is arranged, and the lower end of each vertical spring is fixed on the base, and the upper end is fixed on the top cover.Preferably, the quantity of above-mentioned vertical spring can be 2,4,6,8,10 or 12 or the like; The upper end of above-mentioned each vertical spring can be provided with one section thread segment, links together through thread segment and the adjusting nut 6 that is positioned at top cover top, can make vertical spring with height such as cylindrical drum grade the time, be in the zero elongation state just through each adjustment of regulating nut.On top cover, offer the central hair hole; One vertical leading screw 7 passes the central hair hole and stretches into inner cylindrical tube; The upper end of vertical leading screw is provided with operating grip 8; The lower end is fixed with briquetting 9, and the inner bottom part of inner cylindrical tube is provided with the bottom pad plate 10 that is used to keep flat template lining 15, bottom pad plate be positioned at briquetting under; Preferably, it is round table-like that above-mentioned bottom pad plate becomes, its with the inner tube wall of inner cylindrical tube between formation wedge gap 11.Base is provided with the transverse drain 12 that is used for to extraneous draining, and a termination of transverse drain is gone into the inner bottom part of inner cylindrical tube, promptly inserts above-mentioned wedge gap.The arranged outside of cylindrical drum has Vertical surveyors' staff 13 outside, and Vertical surveyors' staff is fixed on the top cover.Offer the vertical slot 14 that is used to pick and place the template lining at inner cylindrical tube middle and upper part barrel and cylindrical column casing middle and upper part barrel.
Preferably, above-mentioned inside and outside cylindrical drum can adopt transparent material to process, and the barrel thickness of inner cylindrical tube is 3～5mm, and the barrel thickness of cylindrical column casing also is 3～5mm; The interior diameter of above-mentioned inner cylindrical tube can be 100～120mm, and the width of annular space can be 50～75mm; The main scale mark spacing of Vertical surveyors' staff is 1mm, and inferior scale mark spacing is 0.2mm; Above-mentioned vertical slot is between adjacent two springs, and length is 120～125mm, and wide is 10～15mm.
Principle of work of the present invention roughly is:
Regulate nut through adjustment and make all vertical springs be in the zero elongation state at the top cover lower edge during just with inside and outside cylindrical drum upper limb driving fit, this calls demarcation.Whether inspection Vertical surveyors' staff, transverse drain be in shape, and this calls inspection.
Through operating grip rotary vertical leading screw; The drive briquetting rises, and makes the bottom of briquetting be higher than the upper limb of vertical slot, and soaked saturated multi-disc (quantity is counted n) template lining is used the tweezers gripping; Send in the inner cylindrical tube through vertical slot, and the template lining is tiled on the bottom pad plate.
According to on-site concrete build high computational wall pressure size, calculate the spring elongation when reaching this wall pressure and on the outer tube wall of Vertical surveyors' staff and/or cylindrical column casing, mark out the relevant position according to the elasticity coefficient of every vertical spring and number of springs as the precalculated position.
Through the slow rotary vertical leading screw of operating grip, drive briquetting and descend then, pressure holding is tiled in the template lining on the bottom pad plate; The moisture of template lining is discharged, and the top cover vertical spring that moves and stretch on corresponding stops precession in this process when Vertical surveyors' staff reaches above-mentioned precalculated position; After leaving standstill 2 minutes, the vertical leading screw of derotation, make the top cover return after; And the drive briquetting rises; Make the bottom of briquetting be higher than the upper limb of vertical slot, press from both sides out the template lining from inner cylindrical tube, take by weighing the quality (m of template lining immediately with tweezers
1) and measure the area A of single-chip template lining, place baking oven under 45 ℃ of environment, to dry the template lining then to constant weight, take by weighing the quality (m of template lining once more
