Thus deep water drilling accurate positioning problem is amplified out.In addition, part is completed the engineerings such as Face Rockfill Dam strengthening grouting
There are problems that grout hole Underwater Navigation.
Existing deep water boring positioning generally uses water surface setting-out, and borehole coordinate is introduced the bottom or used by lifting rope and is dived under water
Member dives beneath the water setting-out or using the inclinometer measurement modes such as the underwater hole location of guide sleeve degree of skewness inverse.The above various positioning
There are the following problems for mode:
1) lifting rope mode: lifting rope cannot keep plummet state by water currents in the water of library, and boring positioning deviation is very big.
2) diver bottom setting-out: after library water is more than certain depth (generally 60m), diver can not dive or dive
Difficult, the effective time is short.
3) inclinometer measures guide pipe inclination angle mode: low precision, and skew direction inaccuracy, time-consuming.
It can be seen that there are positioning accuracy difference, and bolthole deviations in existing deep water boring positioning mode
It is excessive, curtain uniform force is directly affected, may cause and fail in curtain operational process.In other underwater construction engineerings
Do not allow the error of underwater drilling too big yet.
