At present for needing the pile foundation of ultrasound examination to widely use sound detecting pipe as grouting pipe, sound detecting pipe is made to reach collection ultrasound examination and the effect that is integrated of two kinds of purposes of mud jacking passage, but utilize sound detecting pipe to carry out the construction technology of pile base grouting as mud jacking passage, also having problems with: 1) fluid pressure type sound detecting pipe tube wall is very thin, only 1.2 millimeters, it is difficult with traditional welding at the construction field (site) and sound detecting pipe is effectively connected with casting head；2) traditional welding construction technology not only difficulty is big, and take time and effort, having a strong impact on pile foundation mud jacking speed, pile foundation has irrigated, after treating concrete initial set, weld filling adaptor and open plug to carrying out setting-out at the bottom of stake, after treating on concrete strength, remove the filling adaptor welded and pile foundation is carried out ultrasound examination, finally must weld filling adaptor and carry out pile base grouting, so hydraulic pressure sound detecting pipe must be performed twice at welding, strengthen difficulty of construction and lose time；3) owing to mud jacking pressure is big, reach 3Mpa, add that welding procedure difficulty is big, very easily cause that in mud jacking process, serosity sprays from junction。
Summary of the invention
The technical problems to be solved in the utility model is, exist in construction hydraulic pressure sound detecting pipe must be performed twice at welding for prior art, strengthen difficulty of construction, lose time and owing to mud jacking pressure causes greatly the problem that welding procedure difficulty is big, provide a kind of bored concrete pile mud jacking adapter, sound detecting pipe is utilized to carry out the construction technology of pile base grouting as madjack pipe, reach a pipe dual-purpose, and change convenient purpose, efficient, safe, economic feature simple to operate, easy to use, is particularly well-suited to have the pile bottom grouting of the cast-in-situ bored pile of ultrasound examination to construct。
This utility model be the technical scheme is that by the above-mentioned technical problem of solution
A kind of bored concrete pile mud jacking adapter, including sound detecting pipe and slip casting adapter, sound detecting pipe upper end is provided with slip casting adapter, and slip casting adapter is connected with Grouting Pipe by screw thread, and sound detecting pipe lower end is arranged in bored concrete pile。
Connecing technique scheme, described slip casting adapter is connected with sound detecting pipe by screw thread。
Connect technique scheme, in described slip casting adapter, be provided with sealing ring。
Connecing technique scheme, described sealing ring is rubber ring。
Described sound detecting pipe includes hydraulic pressure sound detecting pipe, sound detecting pipe joint and thin-walled sound detecting pipe, and hydraulic pressure sound detecting pipe lower end is connected with thin-walled sound detecting pipe upper end by sound detecting pipe joint, and thin-walled sound detecting pipe is arranged in bored concrete pile。
Described Grouting Pipe is provided with ball valve。
This utility model has the advantages that
Sound detecting pipe is utilized to carry out the construction technology of pile base grouting as madjack pipe, fluid pressure type sound detecting pipe and slip casting adapter connect in conjunction with transition, sound detecting pipe is made to have reached a pipe dual-purpose, and change convenient purpose, efficient, safe, economic feature simple to operate, easy to use, is particularly well-suited to have the pile bottom grouting of the cast-in-situ bored pile of ultrasound examination to construct。
