Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described.
With reference to Fig. 1, mud sediment analyzer is made up of detector 1, wire rope 2, pulley 3, scalable armed lever 4, hand reel 5, tautness meter 6, vehicle frame 7, depth indicator 8, wheel 9.
With reference to Fig. 2, depth indicator 8 is a mechanical digital formula indicator.
With reference to Fig. 3, detector is by detection dish 11, and feeler 12, detector counterweight 13, scale 14, scale lock 15, feeler counterweight 16, suspension ring 17 are formed.
Fig. 1, Fig. 2 and Fig. 3 have provided an embodiment of the present utility model, the whole bundle of mud sediment analyzer except that detector 1, are installed on the dolly of being made up of vehicle frame 7 and wheel 9; Pulley 3 is fixed on the scalable armed lever 4; By suspension ring 17 tractions, wire rope 2 is connected on the hand reel 5 by pulley 3 one ends detector 1 by wire rope 2, and an end is connected on the suspension ring 17 of detector 1; There is clamping device hand reel 5 inside, and effective lay winding wire ropes 150m, in order to guarantee the measuring dark bored concrete pile sediment of 150m; Tautness meter 6 and mechanical digital formula depth indicator 8 are equipped with in zone in the dolly inside of wire rope 2 processes, and tautness meter 6 utilizes fluid pressure to realize.
As shown in Figure 3, feeler 12 and detection dish 11 are cylindrical; Detection dish 11 has a center pit, has one to coil the feeler 12 of 11 relative motions with detection in the hole, and feeler 12 is a slender cylinder, can slide up and down in center pit; 11 tops are coiled in detection can increase installation detection dish counterweight 13, and feeler 12 tops can increase installs feeler counterweight 16; Scale 14 is fixed on the feeler 12 by scale lock 15, and the resolution of scale 14 can be 1mm, and its maximum scale is 50cm.
During use, dolly is pushed near the boring (groove), opens the clamping device of hand reel 5 inside, when shaking the handle of hand reel 5, detector 1 can transfer or promote along boring (groove), by the hand reel 5 controlled motion speed on ground.Depth indicator 8 shows the degree of depth of detector 1 in mud, and tautness meter 6 also can indicate the resistance that detector 1 is subjected to simultaneously.
Scalable armed lever 4 can be extracted out from vehicle frame 7 in use, and the angle of one 30 degree of can upwards kicking up, and the time spent is not set level in the withdrawal vehicle frame 7.
The basis weight of detection dish 11 is that 20kpa sets by it to the sediment net pressure, also can be according to the height situation increase counterweight of the concrete perfusion first time.During original state the bottom surface of feeler 12 with survey card in same level, and be to move downward with the center pit, the basis weight on the feeler 12 is subjected to the setting of 1Mpa net pressure by feeler 12, also can increase counterweight according to actual conditions.Reaching on the sediment before the interface, feeler 12 and detection dish 11 descend in mud simultaneously, on reaching sediment during the interface, detection dish 11 stops to descend, and feeler 12 still continues to descend, feeler 12 also stops to descend when being subjected to more than the 1MP (counterweight that comprises increase) resistance up to feeler 12 bottom surfaces, the difference in height that this moment, feeler 12 bottom surfaces and detection were coiled between 11 cards is sediment thickness, show by scale 14, the meter full scale of scale is 0-50cm, and scale 14 is locked by scale lock 15 when promoting detector 1, and is no longer mobile, so when detector 1 was raised to ground, yardstick shown in the scale 14 still was the thickness of sediment.Can survey the sediment thickness scope is 0-50cm.
Survey the detection dish 11 of mud and sediment boundary (interface on the sediment), its weight is height and the weight and predefined according to the concrete perfusion first time, and this detection dish 11 is sinking and be suspended in interface on the sediment naturally in mud; Survey the feeler 12 of sediment and following undisturbed soil boundary (interface under the sediment), pass the center pit of detection dish 11,, set the weight of feeler 12, make feeler 12 sink to the original state soil layer with deadweight according to the undisturbed soil bearing capacity that has recorded.If the user allows to measure till the 1Mpa, also can be set at 1Mpa to the pressure of feeler.
The foregoing description of the present utility model can be realized with other variety of ways.For example, chute being set on the top of armed lever 4 comes guiding steel wire rope 2 in order to substitute the effect of pulley 3; Feeler 12 coils 11 routing motions by groove and detection and substitutes the motion of original feeler 12 in the center pit of detection dish 11; Take power-actuated method to substitute original manual mode to reel 5.
Below only be preferred embodiment of the present utility model, any modifications and changes of doing according to the utility model all should be included in the protection domain of the present utility model.
