Have 5 pressure transducers in the utility model, in the vertical direction is spaced apart, and namely spacing equidistantly distributes in the intercropping of 0.1-1.0 rice, and requires that position is fixing all the time and can not change, otherwise error effect that can be very large to surveyed data generation below.
Buckle 16 tube walls that monitor of the present utility model can be made to be attached to conduit 3 directly to install.
Concreting continuous monitoring instrument of the present utility model is also installed by the extension radial distribution of support 18 along conduit 3, as shown in Fig. 3 and Fig. 4 a-c, bigeminy (Fig. 4 c), three (Fig. 4 b), the tetrad (monitor of Fig. 4 a) or more connection are installed, by noticing during support installing that support is round and smooth, to assume diamond in shape or olive shape can not hinder conduit freely up and down.Each monitor in the utility model can reflect the concrete in the axial direction pouring quality of position stake, and the radial area that each monitor connects shared stake is larger, more accurately can reflect the total quality of stake.
The utility model application in a particular embodiment, can be shown in Figure 1, and the bored concrete pile in engineering puts into steel reinforcement cage 2 in stake holes 1, then stretch into feed conduit 3; The bottom of conduit 3 is provided with conduit mouth 6, for discharge; Top is provided with hopper 4, for charging.During construction, conduit 3 is stretched in steel reinforcement cage 2, first staying only with a certain distance from stake holes bottom surface, by hopper 4 material feeding, and then defining multiple fluid aspect from bottom to top in the bottom of stake holes 1: the continuous concrete layer 10 of flowing, mud and concrete mixolimnion 9, slime water 8 and water 7; Continue charging, cast after first watering, conduit 3 slowly promotes, and progressively completes the concreting of whole stake holes.
Application the utility model, when can build based on monitoring, whether concrete differentiates the quality of pile foundation continuously, comprises the following steps successively:
(1), before building beginning, the exit position bottom the feed conduit 3 of bored concrete pile, vertically highly arranges 5 pressure transducers 11 along conduit 3, as one group of monitor (see Fig. 2); 3 groups of such monitors can be set altogether, and by support 18 along the extension radial distribution of conduit 3, namely arrange equably (see Fig. 4 b) by 120 degree of angles;
(2) in casting process, obtain the data on each pressure transducer 11 by data acquisition unit 12, and transfer in data integration processor 13, then be sent to computing in computer system by data transmission port 15; Comprise process software, the storage of data high in the clouds etc.;
(3) according to pressure differential formula, calculate and build Media density ρ between 2 pressure transducers
ρ＝ΔP
A-B/(gΔH)K
In formula: Δ P
a-Bit is the pressure differential between 2 pressure transducers;
G is gravitational constant;
Δ H is the distance between 2 pressure transducers, is fixed value;
K is correction factor;
(4) along with casting process, promote conduit gradually, repeat step (2) and (3) record ρ value;
(5) after having built, 3 groups of data will be obtained, and often organize data and can differentiate this axially whether continuous whole of position, differentiate whether this stake is continuous whole in concreting process accordingly, thus judge this quality.Specific practice is: judge ρ value whether continous-stable and consistent with built concrete ρ value; In this way, then show that the path of passing by between these 2 pressure transducers is all continuous print concrete, this axial concrete namely on this group monitor position is continuity, therefore this axially concrete curing after also should be continuous whole.
The theory calculate of the method is according to as follows:
Shown in Fig. 5, equidistantly be provided with A, B, C, D, E... mono-group of pressure transducer vertically at concreting continuous monitoring instrument, the distance, delta H between sensor is generally 0.1 meter-1.0 meters, is worth little i.e. sensor arrangement and obtains close, monitoring is accurately, also high to the accuracy requirement of sensor; Value greatly i.e. sensor arrangement obtains sparse, and monitoring accuracy is bad.
When under conduit to bottom pile foundation during casting concrete, A, B, C, D, E... respectively organize the pressure effect that sensor is subject to residing plane separately, the effect of the tens of kinds of power such as what in the disturbance that the flowing of the pressure having water pressure, mud pressure, slurry concrete mixture pressure, concrete pressure, sidewall to produce, concrete produces, impulsive force and concrete, uneven block of strong produce were raw covers, impact, each pressure sensor monitoring is to the pressure value P of present position
a, P
b, P
c, P
d, P
e
Because stressed relation is very complicated, according to single P
a, P
b, P
c, P
d, P
enumerical value is difficult to draw useful parameters relationship, but the difference between two sensors: Δ P
a-B=P
a-P
b=K ρ g (H
a-H
b)=K ρ g Δ H
In formula, K is the correction factor of A, B inequality by wall pressure, disturbing force, impulsive force and other acting force, and under field condition, spacing (Δ H) value of A, B is very little, can regard K=1 as;
Then: Δ P
a-B=ρ (g Δ H)
ρ is the density of medium between A, B;
G is gravitational constant;
Distance when Δ H is installation between A, B sensor is constant;
It can thus be appreciated that the reading difference between A, B sensor, can reflect the density of the medium between A, B, and density is the characteristic of material, has concrete (fluidised form), water, slime water and the potpourri between them building on-the-spot medium between A, B, density is different, by Δ P
a-Bit is that data can predict between A, B sensor for which kind of medium.After building beginning, until terminate the ρ=Δ P as recorded
a-B/ (g Δ H) is consistent with the concrete ρ that we build, then can judge that the path that A, B sensor is passed by casting process is all continuous print concrete, and namely this axially concrete of monitor position is continuous print.Δ P
a-C, Δ P
b-Cetc. then can mutually verify, to eliminate the error of sensor.
Finally, it is also noted that what enumerate above is only a specific embodiment of the present utility model.Obviously, the utility model can also have many distortion, all distortion that those of ordinary skill in the art can directly derive from content disclosed in the utility model or associate, and all should think protection domain of the present utility model.
