Description
Technical field
The present invention relates to a kind of pressure activated formula underwater cast-in-place pile and control devices and methods therefor, belong to building engineering construction field.
Background technology
Concrete is modal a kind of construction material in Construction of Civil Engineering, purposes widely, in the construction of building etc.
In play important role.During water-bed pile foundation construction, bored concrete pile generally requires segmentation and pours.But water in segmentation
When building, due to operational error and all irresistible factors of workmen, usually there will be the super filling of this stage, or fill
Situation at the designed elevation in note not up to this stage.If there is super filling phenomenon, excavate the soil body after pile foundation molding, it is necessary to use
Manually by the concrete chisel removal of super filling, until the elevation location of this stage design, this can directly influence construction speed and dirt
Dye ecological environment；Situation if there is perfusion not up to designed elevation, it is necessary to carry out supplementary irrigation measure, indirectly have influence on
The intensity of pile foundation.In China, the loss that these production accidents the most thus bring is immeasurable.
The patent of entitled " underwater concrete pouring level position indicator " of Patent No. CN100483081C, discloses a kind of inspection
The method of concrete absolute altitude location when surveying bored concrete pile underwater grouting.Patent No. CN 202139616 U, entitled " a kind of concrete
Bored concrete pile height controller under water " patent disclose a kind of underwater elevation controller for cast-in-place concrete pile, its structure is: " institute
Arranging Underwater Pressure induction apparatus on the steel reinforcement cage stated, described Underwater Pressure induction apparatus is by by described cast-in-place concrete pile top
The metal lead wire that portion draws connects the pressure alarm being arranged on ground." but foregoing invention has the disadvantage in that
1, pressure transducer is conventional model, does not has specific aim, is easily damaged under water in the concreting process of bored concrete pile；
2, structure does not has corresponding water-proof protection device, under the most this special working condition, easily soaks, in causing
The short circuit of portion's circuit, even damage；
3, traditional sensor is electronic sensor, when being reported to the police by instantaneous pressure in certain direction of probe, therefore cannot
Avoiding conduit to move up and down the concrete caused and gush the uniaxial pressure triggering caused on suddenly, the accuracy of warning cannot be protected
Barrier.
Summary of the invention
The present invention is to solve the problems referred to above, it is proposed that a kind of pressure activated formula underwater cast-in-place pile absolute altitude positioner and use thereof
Method, the pressure probe in this device is fixed on inside steel reinforcement cage and transfers to Pile Foundations Design absolute altitude, due to concrete and mud
The component of slurry differs widely, and to result in the two differing pressure produced at identical height very big, has change clearly, works as coagulation
When soil rises at this device, concrete gives pressure around pressure probe, makes originally not closing in pressure probe
Copper sheet pressurized Guan Bi connect circuit, hand-held alarm in this device is reported to the police, therefore, it is possible to give workmen the most intuitively
Alarm signal.
