Technical field
The present invention relates to pile foundation construction field, specifically a kind of underwater brill that can be monitored cast-in-place pile concrete and pour height
Hole pouring pile construction dynamic monitoring method.
Background technology
With the fast development of building trade, the use of underwater concrete filling pile also gradually increases, for example some are high-rise
Building basis, underground chamber, subterranean tunnel, bridge, harbour, harbour basis etc., the basis of particularly some skyscrapers are set
Meter, to make full use of urban underground space, almost most of high-rise and high-rise building is designed with 1-3 layer basements, often
Underwater gliders are carried out using cast-in-situ bored pile.
Underwater gliders are tremie method and pump pressure method using more method at present, and wherein tremie method use is the widest
It is general, specifically using the steel pipe of sealed connection (or intensity higher hard non-metallic pipe) as the perfusion channel of underwater concrete,
Its bottom is embedded in the concrete stirring thing poured into appropriate depth, under certain head pressure effect, is formed continuous close
Real concrete pile body.The designed elevation of cast-in-place concrete pile stake top is usually descended often in below ground 3-20m or so, coagulation
Because the presence of slurry mixture, the true absolute altitude of concrete surface are difficult to be properly positioned control in native filling process.Carrying out coagulation
Soil does not have bored concrete pile pouring to stop starching monitoring means when pouring, often cause the universal superelevation 1-5 rice of bored concrete pile, very cause more than 5 meters,
Cause the waste of substantial amounts of construction material.And also need to cut stake in excavation of foundation pit, difficulty of construction is both added, is consumed again
Substantial amounts of cost of labor, while manufactured substantial amounts of building waste.
The content of the invention
The present invention can monitor whether stake top reaches the underwater of predetermined absolute altitude in real time according to the deficiencies in the prior art offer is a kind of
Bored pile construction dynamic monitoring method, the monitoring method are to be stretched into using dynamic monitoring probe in mud, utilize difference
Monitoring and sound prompt function, it can be ensured that stake top absolute altitude is avoided because bored concrete pile superelevation in the range of defined reasonable superelevation
Caused by waste of material and cost of labor.
