Abstract
A device of measuring underwater concrete face lifting height, comprises lining rope, and lining rope lower end is connected with counterweight, and counterweight bottom is fixedly connected with taking out cylinder, and the bottom of taking out cylinder is provided with the reverse stop valve upwardly opening.Adopt above-mentioned measurement mechanism to measure a method for underwater concrete face lifting height, comprise the following steps: described measurement mechanism is put into slotted eye; Repeatedly promote and transfer measurement mechanism, sediment or concrete rest on to be taken out in cylinder; Take out described measurement mechanism, the material of taking out in cylinder by observation judges that whether measurement mechanism enters into concrete, then determines the lifting height of slotted eye inner concrete face according to the scale of lining rope; By said method, complete the measurement to underwater concrete face lifting height.The utility model can be determined the lifting height of slotted eye inner concrete face like clockwork, and guidance is built rising of conduit and pulled out, and prevents that diaphram wall (bored concrete pile) from the accidents such as " disconnected wall ", " broken pile " occurring, and guarantee construction quality.
Description
Technical field
The utility model relates to underwater concrete planar survey field, particularly a kind of device of measuring underwater concrete face lifting height in diaphram wall (bored concrete pile) slotted eye.
Background technology
At present, in carrying out diaphram wall (bored concrete pile) slotted eye during underwater concreting, the general lifting height that adopts " plummet " or " survey cake " to measure slotted eye inner concrete face, instructs and builds rising of conduit and pull out.
During measurement, operator puts into slotted eye by " plummet " or " survey cake ", raise and decentralize " plummet " or " survey cake ", with sensation judgement " plummet " or " survey cake ", whether arrive on concrete layer, then according to the scale above lining rope, determine the lifting height of concrete surface, with this, instruct and build rising of conduit and pull out.
In concreting process, along with the not only rising of slotted eye inner concrete face, the concrete material being scattered in hole wall mud skin, the silt particle in mud and aperture around all can deposit on underwater concrete surface layer, forms the thick sediment of one deck under water.
For ultra-deep underground continuous wall (bored concrete pile), because the time of building is longer, particularly enter eventually and water the stage, sediment is more and more thicker, sensation with operator judges whether " plummet " or " survey cake " arrives on concrete layer, and difficulty is increasing entirely, tends to form erroneous judgement, cause the accidents such as " disconnected wall ", " broken pile " to occur, directly affect the construction quality of diaphram wall (bored concrete pile).
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of device of measuring underwater concrete face lifting height, can Measurement accuracy underwater concrete face lifting height, and instruct and build rising of conduit and pull out.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of device of measuring underwater concrete face lifting height, comprise lining rope, and lining rope lower end is connected with counterweight, counterweight bottom is fixedly connected with taking out cylinder, and the bottom of taking out cylinder is provided with the reverse stop valve upwardly opening.
The described cylinder of taking out is connected with counterweight by many reinforcing bars.
The internal diameter of taking out cylinder is 90～110mm.
Adopt above-mentioned measurement mechanism to measure a method for underwater concrete face lifting height, comprise the following steps:
One, when carrying out the measurement of slotted eye inner concrete face lifting height, described measurement mechanism is put into slotted eye;
Two, when described measurement mechanism enters after sediment, because the density of sediment is larger, measurement mechanism can be obstructed and stop;
Three, repeatedly promote and transfer measurement mechanism, promote and transfer highly about 0.5m, in lifting and decentralization process, take out a lower end reverse stop valve and constantly open and close;
While four, transferring measurement mechanism, sediment or concrete are entered and are taken out in cylinder by reverse stop valve, while upwards promoting this measurement mechanism, take out cylinder reverse stop valve below and close downwards, and sediment or concrete rest on to be taken out in cylinder; By repeatedly raising and decentralizing this device, on the one hand sediment or concrete are packed into and take out cylinder; On the other hand, measurement mechanism enters into sediment or concrete downwards in the effect of gravity;
Five, take out described measurement mechanism, the material of taking out in cylinder by observation judges that whether measurement mechanism enters into concrete, then determines the lifting height of slotted eye inner concrete face according to the scale of lining rope;
By said method, complete the measurement to underwater concrete face lifting height.
A kind of device of measuring underwater concrete face lifting height that the utility model provides, can determine like clockwork the lifting height of slotted eye inner concrete face, guidance is built rising of conduit and is pulled out, prevent that diaphram wall (bored concrete pile) from the accidents such as " disconnected wall ", " broken pile " occurring, and guarantee construction quality.

Embodiment
Embodiment 1:
In Fig. 1～2, a kind of device of measuring underwater concrete face lifting height, comprises lining rope 1, and lining rope 1 lower end is connected with counterweight 2, and counterweight 2 bottoms are fixedly connected with taking out cylinder 4, and the bottom of taking out cylinder 4 is provided with the reverse stop valve 5 upwardly opening.Preferably, the described cylinder 4 of taking out is connected with counterweight 2 by many reinforcing bars 3.Taking out cylinder 4 lower ends welding valve circles, a reverse stop valve upwardly opening 5 is installed, so that sediment 6 and concrete seven can only enter and take out cylinder 4 and can not discharge on valve circle.
Preferably, taking out cylinder 4 internal diameter is 90～110mm.In this example, adopt take out cylinder 4 diameters be 91mm.
Embodiment 2:
Adopt the measurement mechanism described in embodiment 1 to measure a method for underwater concrete face lifting height, comprise the following steps:
One, when carrying out slotted eye 8 inner concrete face lifting heights measurement, described measurement mechanism is put into slotted eye 8;
Two, when described measurement mechanism enters after sediment 6, because the density of sediment 6 is larger, measurement mechanism can be obstructed and stop;
Three, repeatedly promote and transfer measurement mechanism, promote and transfer highly about 0.5m, in lifting and decentralization process, take out a lower end reverse stop valve 5 and constantly open and close;
Four, because workability and the mobility of sediment 6 and concrete seven are better, while transferring measurement mechanism, sediment 6 or concrete seven are entered and are taken out in cylinder 4, while upwards promoting this measurement mechanism by reverse stop valve 5, take out cylinder 4 reverse stop valve 5 below and close downwards, sediment or concrete rest on to be taken out in cylinder; By repeatedly raising and decentralizing this device, on the one hand sediment or concrete are packed into and take out cylinder; On the other hand, measurement mechanism enters into sediment or concrete downwards in the effect of gravity;
Five, take out described measurement mechanism, the material of taking out in cylinder 4 by observation judges that whether measurement mechanism enters into concrete seven, then determines the lifting height of slotted eye 8 inner concrete faces according to the scale of lining rope 1;
By said method, complete the measurement to underwater concrete face lifting height.
