Description

Subaqueous concreting absolute altitude control equipment

Technical field

The utility model relates to a kind of blipology, especially a kind of subaqueous concreting absolute altitude control equipment.

Background technology

Along with the fast development of China's infrastructure construction and real estate, the filling concrete amount increases increasingly, according to the interrelated data statistics, wherein has 10 ~ 30% to be used for ± 0.00 following engineering in the concrete field of using.Such as high-rise basis, underground chamber, subterranean tunnel, bridge, harbour, harbour basis etc., particularly the basic engineering of the bridge of soft clay area, harbour, harbour and skyscraper often adopts cast-in-situ bored pile, carry out the underwater concrete perfusion, because the exploitation of the underground space, the designed elevation on stake top is often at below ground, in the filling concrete process because of the existence of slurry mixture, the difficult correct positioning control of the true absolute altitude of concrete surface, often adopt the method for estimation, the certain height of the super filling of absolute altitude in design causes the increase of filling concrete amount.Especially obvious in the work progress of Tall Building Foundation cast-in-situ bored pile, every pile often needs the super 2 ~ 4m of filling, cause on the one hand the serious waste of concrete resource, caused again simultaneously the difficulty of foundation excavation, increased on the other hand construction cost and the project construction cost of project, brought again simultaneously how to bury and processed the pollution problem that unnecessary concrete is abandoned piece.And when designed elevation when below ground surpasses 6m, the absolute altitude location will more difficult, sometimes even the filling concrete absolute altitude can occur and owe to fill with not in place, generation has a strong impact on to construction quality.

How underwater concrete perfusion controls the underwater perfusion absolute altitude of concrete well, reaches the requirement of design perfusion absolute altitude, does not also detect preferably so far control method, does not also have special detecting instrument and equipment.

The utility model content

The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, provide a kind of simple to operate, detection accuracy is high, anti-interference, measure easily subaqueous concreting absolute altitude control equipment.

For achieving the above object, the utility model adopts following technical proposals:

A kind of subaqueous concreting absolute altitude control equipment, comprise the sound-pipe that is arranged in the priming concrete pile hole, the sound-pipe below is provided with the pressure transducer at the place, summit that is positioned at pre-designed concrete height, pressure transducer links to each other with the signal transmission apparatus that is positioned at the sound-pipe top by the optical cable that passes sound-pipe, and signal transmission apparatus links to each other with data processing equipment.

Described signal transmission apparatus comprises the wireless transport module that is positioned at the sound-pipe top, and wireless transport module links to each other with the reception of wireless signals module by wireless signal, and the reception of wireless signals module links to each other with data processing equipment.

Described data processing equipment comprises the demultiplexer that links to each other with the reception of wireless signals module, and demultiplexer links to each other with single-chip microcomputer by A/D converter, and single-chip microcomputer links to each other with host computer.

The using method of subaqueous concreting absolute altitude control equipment, 1) sound-pipe is put into priming concrete pile hole, according to the Concrete Design height, pressure transducer is fixed on place, grouting summit; 2) in sound-pipe, be provided with optical cable and pressure transducer is connected with wireless transport module; 3) pour into along with concrete, the corresponding rising of concrete raised floor, when rising to the Concrete Design height and position, the pressure transducer pressurized produces simulating signal, arrives wireless transport module by optical cable transmission; 4) be sent to wireless signal receiver by wireless transport module again, and the input signal separation vessel carries out signal and separate, be transferred to A/D converter thereupon, generate simulating signal; 5) A/D converter becomes digital signal with the analog signal conversion that generates, then send into single-chip microcomputer, the function program of single-chip microcomputer by having inputted is presented on digital signal on the host computer with redness warning form, the final monitoring that realizes the grouting critical point, thus the wireless monitor network formed.

The beneficial effects of the utility model are, the utlity model has simple to operate, detection accuracy is high, anti-interference, measure the advantages such as convenient.
