Description
Technical field
It is especially a kind of for judging practical filling concrete the utility model relates to the filling concrete field in civil engineering
Height whether weight-driven in place.
Background technique
In foundation construction, it is often necessary to the concrete perfusion into pore-forming, the pore-forming refer to by drilling, punching, explosive expansion,
The hole that the modes such as immersed tube, artificial are constructed into, the process for filling concrete is usually that the bottom of pore-forming is inserted into a Grouting Pipe, then under
It is up in the milk, concrete liquid level can turn over from lower to upper at this time.
Encountered in practice of construction the soil body it is softer when, it is often necessary to drilling while carry out mud off, this is just formed
Mud layer in hole, and hole wall hack is fallen and hole in existing other impurities such as sand etc. will form laitance layer, that is,
It says, it, will outwardness three layers of different substance, the i.e. concrete layer of bottom, middle part in pore-forming during filling concrete
Laitance layer and the mud layer on top.
When the prior art fills concrete to pore-forming, one technical problem of objective reality that is, can not essence using existing technological means
Really know actual filling concrete height, in other words, prior art means can not accurately determine whether practical filling concrete height reaches and set
Calibration is high.Weight is tied up to lining rope lower end and weight hangs in pore-forming by the measurement method for such as utilizing weight and lining rope, and will
Lining rope is slowly transferred, and in the ideal situation, weight can sequentially pass through mud layer and laitance layer, and is eventually arrived at concrete layer and floated
On the interface of pulp layer, and got up by the complete jacking of concrete layer, causes lining rope relaxation that can not continue to transfer, in this way, worker is just
It can judge that weight has arrived at according to feel and fill concrete height, then slightly above mentioning lining rope keeps its exceptionally straight and read lining rope this moment
Length, can be obtained fill concrete height.But it is found in practice of construction, it is existing after viscosity also increases as laitance layer depth increases
The weight of technology, which may can not be successfully, passes through laitance layer, but is got up by the hovering of laitance jacking, in this way, the weight of the prior art is very
Concrete layer can not be extremely reached, therefore can not judge actual filling concrete height；Moreover even if weight smoothly reaches concrete layer,
Rely only on the experience, lining rope slackness and the specific feel of decentralization of worker only to judge, interference from human factor is too big, and pole is not smart
Really.
It certainly can also be high substantially to obtain a filling concrete according to total groundwater increment of concrete divided by the sectional area of drilling
Degree, but above-mentioned conversion method accuracy is too low, and due to the presence of reaming, pore-forming aperture is inconsistent to cause to be difficult to estimate, nothing
Method instructs practice of construction.So the prior art generally takes such as 1 meter of superfilled certain altitude of mode to construct, for example set
Fill concrete absolute altitude be 9 meters, it is necessary to be filled into 10 meters, with ensure fill concrete it is abundant, and then guarantee pile quality, but it is superfilled will necessarily
The waste for causing concrete material, leads to increased costs, does not also meet energy-saving and environment-friendly needs.
Utility model content
The technical problems to be solved in the utility model be to provide a kind of judgement it is accurate, easily and fast for judging reality

It has the advantage that.
The test philosophy of above-mentioned apparatus are as follows: with turning over for concrete, the weight for being suspended in setting height can be contacted successively
Three layers of mud, laitance and concrete substance；When weight is hanging, spring dynamometer measures the gravity of weight, but when weight impregnates
When, by buoyancy or jacking force, the value of spring dynamometer can be reduced, specifically, weight in mud layer by buoyancy, by
In buoyancy very little, therefore the value slight decrease of dynamometer；And when in half-dried half dilute laitance layer, as soaking depth increases, float
Slurry viscosity increases, and the main stress of weight can be changed into jacking force by buoyancy, and the amplitude that the value of dynamometer reduces under this state can increase
Greatly, but still it is unobvious；And only, by the complete jacking of concrete layer, it can just make spring when weight starts to contact concrete layer
The test value of formula dynamometer reduces rapidly, in this way, test value curve in laitance slowly by a small margin reduce with it is fast in concrete
Speed be greatly lowered between there are an inflection points, once capture this inflection point, so that it may it is accurate to determine that concrete layer reaches weight
Height where hammering into shape, that is, reach setting absolute altitude.Using the device implement judgment method, as a result precisely, process quickly,
It is easy to operate；After even dynamometer is connect with master controller, analysis can be gone as a result, obtaining curve simultaneously by master controller completely
It voluntarily captures inflection point and is judged, be completely dependent on artificial judgment compared with prior art, the deterministic process of the application is more convenient
Fast, and it is obvious more accurate；Due also to weight is hollow, so, it is packed into suitable filler, to adjust the ratio of weight
Weight, so that it may ensure that weight can smoothly pass through mud layer and laitance layer, and finally just hover on concrete layer, prevent existing
There is weight in technology to further ensure that the accurate of measurement judgement by the interference of the big laitance layer jacking of viscosity；And below weight
Sharp portion can further ensure that weight more smoothly sinks in mud and laitance, and further convenient measurement process simultaneously guarantees to measure
Accuracy.
