Abstract

A position indicator of underwater concrete filling elevation is composed of ground control unit, measuring probe and signal cable. It is featured as designing underwater transducer and confirming measurement calculation parameters according to media property of concrete and slurry as well as water in joining underwater concrete filling course, applying one or multiple transducer to monitor position variation of concrete and slurry in real time and sending out alarm signal by ground monitoring alarm and elevation display when variation is on threshold value.

Description

Underwater concrete pouring level position indicator
Affiliated technical field
The instrument of monitoring concrete (concrete) absolute altitude when the present invention relates to bored concrete pile underwater grouting in a kind of foundation works is mainly used in the monitoring of concrete absolute altitude in the filling process of the priming concrete pile hole in the large foundation engineerings such as skyscraper, bridge, port and pier, offshore production platform and nuclear power station.
Background technology
Flourish along with China's engineering construction cause, bored concrete pile foundation extensively adopts in heavy constructions such as skyscraper, bridge, heavy factory building, port and pier, offshore production platform and nuclear power station, has become most important a kind of foundation works form in the engineering construction.The increase of the extensive employing of bored concrete pile foundation and the stake degree of depth, the concrete pouring amount increases day by day, and according to the interrelated data statistics, major part is all in ± 0.00 following engineering in concrete pouring use field.As foundation workss such as high-rise basis, underground chamber, subterranean tunnel, bridge, harbour, harbours, all adopt underwater concrete pouring in bridge, harbour, harbour and high rise building foundation especially.How to judge that in engineering reality the absolute altitude of concrete pouring, the degree of depth of accurately determining concrete pouring become the important engineering problem that presses for solution.
Owing to there is the difficult correct positioning control of true absolute altitude of the potpourri thereby the concrete surface in the cast of mud more than the concrete pouring face, in engineering construction in the past, often adopt the method for estimation, for guaranteeing the reliability of groundwater increment, often cause the increase of concrete pouring amount.Especially obvious in Tall Building Foundation Bored Pile Construction process, every pile often needs many perfusion 2-4m, causes the serious waste of concrete resource on the one hand, has caused the difficulty of foundation excavation simultaneously; Increased the construction cost and the project construction cost of project on the other hand, and brought how to bury and handled the problem of environmental pollution that unnecessary concrete is abandoned piece.If estimation is not enough, then cause the concrete pouring absolute altitude not enough, influence the foundation works quality.
How underwater concrete pouring controls the underwater perfusion absolute altitude of concrete well, reaches the requirement of design perfusion absolute altitude, does not also have corresponding monitoring method at home, there are not special monitoring instrument and equipment yet, adopt the method for estimation, the accuracy extreme difference is wasted big or quality can not guarantee; There are not special monitoring instrument or equipment in the world yet.
Summary of the invention
The present invention is by the physical property measurement method and the sensitivity characteristic test analysis of media such as concrete, mud, water in the underwater concrete pouring process, underwater concrete pouring absolute altitude location underwater sensor structure and absolute altitude are determined, researchs such as underwater concrete pouring absolute altitude location survey calculation of parameter and ground surveillance alarm control method have proposed underwater concrete pouring absolute altitude localization method and have developed underwater concrete pouring level position indicator device equipment.The gordian technique of this instrument be fill orifice in filling process, the pressure of mud and the pressure of concrete have tangible difference, by measuring the location that this difference realizes concrete pouring absolute altitude (or degree of depth).
Description of drawings
The present invention is further described below in conjunction with accompanying drawing.
Accompanying drawing is a structure principle chart of the present invention.Underwater concrete pouring level position indicator is made up of two parts: (1) is measuring sonde among the figure; (6) be terrestrial contr.
Among the figure: (2) pressure transducer tin hat, protection pressure transducer usefulness will be taken off in actual use in the transportation;
(3) pressure transducer;
(4) pressure signal is gathered transfer circuit;
(5) signal cable;
(7) pressure signal receiving circuit;
(8) keypad;
(9) absolute altitude or depth displays;
(10) locating alarm.
Embodiment
At first remove pressure transducer tin hat (2), measuring sonde (3) and terrestrial contr (6) are coupled together opening power with signal cable (5); Measuring sonde (1) is put into the absolute altitude position (or degree of depth) of the design perfusion of the bored concrete pile that needs perfusion, and this position should be consistent with pressure transducer (3) position; , show the absolute altitude (or degree of depth) of this moment value input terrestrial contr (6) from keypad (8) by absolute altitude (or degree of depth) display (9); Pressure transducer this moment (3) should be in the mud, and pressure transducer (3) begins to measure the force value of mud, as the benchmark of pressure differentiation; Along with the increase of concrete pouring amount, the concrete pouring face in the priming concrete pile hole constantly raises, and when the concrete pouring face touched pressure transducer (3), pressure transducer (3) can be experienced the significant change of pressure; Pressure signal is gathered transfer circuit (4) variation of this pressure signal is gathered out, and sends to pressure receiving circuit (7) in the terrestrial contr (6) immediately by signal cable (5); After pressure receiving circuit (7) receives pressure change signal, compare with the mud pressure reference value; When changing value surpassed given threshold value, pressure receiving circuit (7) drove locating alarm (10) immediately and sends the high frequency chimes of doom, the numerical value flicker that absolute altitude (or degree of depth) display (9) is shown; This moment, the absolute altitude (or degree of depth) of concrete pouring reached designing requirement.

Claims (3)

1. the instrument of the absolute altitude of concrete when monitoring a bored concrete pile underwater grouting location, absolute altitude (or degree of depth) position of determining to pour into concrete by the variation of measuring medium in the priming concrete pile hole.Its characteristic feature is: adopt the change in location of media such as concrete, mud in the single or multiple pressure sensor monitoring concrete pouring processes according to the difference of the rerum natura of media such as concrete, mud in the underwater concrete pouring process and sensitivity characteristic, ground monitoring alarm and absolute altitude (or degree of depth) display provides tangible alerting signal when variation reaches threshold value.
2. underwater concrete pouring level position indicator according to claim 1 is characterized in that adopting single or multiple pressure transducers, by output valve variation monitoring concrete pouring absolute altitude (or degree of depth) position of pressure transducer.
3. underwater concrete pouring absolute altitude according to claim 1 (or degree of depth) orientator is characterized in that by pressure sensor monitoring concrete pouring absolute altitude (or degree of depth).
