Description
Technical field
The invention belongs to what taper pile construction field in architectural engineering more particularly to a kind of high inclination-angle taper pile steel reinforcement cage were transferred to apply
Work method.
Background technique
With the rapid development of domestic and abroad bridge technology, multiarch bridge, Deck Arch Bridges, steel arch bridge etc. have landscape,
The bridge structure form for meeting landform requirement is come into being, and not only embodies the design level of designer, and to different types of rridges
A kind of verifying of construction method.The Engineering Projects of taper pile involved in Arch Bridge Construction is more, and underwater taper pile is also relatively universal, mostly big straight
The taper pile of diameter is designed as full face inclined steel-pipe pile more, using tunneling boring impact holing, impact holing equipment also at home and abroad compared with
Maturation, but excavated by manual work is mostly used both at home and abroad without mature construction technology and equipment for minor radius, the taper pile design of High angle
The construction method in hole ensures the quality and safety constructed, but there is the disadvantage of many quality control in the construction process, because
The special construction principle of taper pile, and influenced by geographical environment and geological condition, collapse hole is also easy to produce during manually digging hole
And water burst phenomenon.Therefore the generation of these hidden danger how is avoided in work progress at the scene, other than carrying out advance support measure, also
Need to avoid the generation of some quality, safety accident using effective construction method.
In High angle taper pile work progress, after stake holes pore-forming, after indices meet the requirements on inspection, that is, steel is installed
How muscle cage guarantees the installation effectiveness and quality of steel reinforcement cage because of the stake holes of High angle, while ensuring the thickness of protective layer uniformly simultaneously
The safety problem for guaranteeing work progress, is the practical problem that technical staff faces at the scene.
Summary of the invention
The technical problems to be solved by the present invention are: providing a kind of construction method of high inclination-angle taper pile steel reinforcement cage decentralization, mention
Efficiency, quality and the safety of high work progress.
In order to solve the above-mentioned technical problem, the invention discloses a kind of high inclination-angle taper pile steel reinforcement cage decentralization construction method,
It is further comprising the steps of including aperture, laying steel mesh, the preamble work for setting up steel arch-shelf and gunite concrete:

To 1/2~3/4 that the laying density of reinforcing bar and transverse steel is predetermined density；
Step 2: being laid with conduit in taper pile aperture, and clears up concrete surface on steel arch-shelf and expose reserved pad；Step
Rapid three: the steel reinforcement cage semi-finished product made in step 1 are hoisted to taper pile aperture with lifting machine, after slinging pre-determined tilt angle,
Entire steel reinforcement cage is snapped down to bottom hole along conduit；
Step 4: by steel reinforcement cage semi-finished product by temporary weld reinforcement welding in pad reserved on steel arch-shelf；
Step 5: laying density is increased to predetermined density by the longitudinal reinforcement and transverse steel of banding steel cage.
Further, conduit is hollow steel pipe in the step 2, and outer diameter is identical as the thickness of steel bar cage protecting layer, institute
Steel bar cage protecting layer is stated as steel reinforcement cage outer edge to the default spacing between steel arch-shelf inward flange.
Further, conduit has 2~5 in the step 2.
Further, root is gone back after the longitudinal reinforcement and transverse steel to predetermined density of banding steel cage in the step 5
Need to increase lateral fixed steel bars according to scene, the transverse direction fixed steel bars binding is located at longitudinal reinforcement end in bottom hole.
Further, after qualification of checking on the quality, withdrawal conduit.
Further, end of conduit is equipped with symmetrical perforation in the step 2, and the perforation is passed through suitable for cable wire.
Compared with prior art, the present invention can obtain following technical effect:
1) steel reinforcement cage is first fabricated to semi-finished product again by the way that in conduit auxiliary decentralization to hole, the program has not been needed in the present invention
Be laid in Quan Kong and steel reinforcement cage be simultaneously installed, nor by steel reinforcement cage integral manufacturing it is good after transfer again, program one side is and complete
It is laid in hole and steel reinforcement cage is installed compared to improving installation effectiveness and quality；On the other hand with by steel reinforcement cage integral manufacturing it is good after
Transferred again compared to improving installation quality and safety because integral manufacturing it is good steel reinforcement cage overall weight it is too heavy, loop wheel machine handling and
There are very big security risks in decentralization process, have recessive danger to operating personnel and other construction equipments；And first by steel reinforcement cage
Semi-finished product are fabricated to again by conduit auxiliary decentralization to the method in hole, conduit has ensured installation effectiveness, while ensuring protection
The thickness of layer is uniform, and greatly improves construction safety and total quality.
2) steel reinforcement cage is first fabricated to semi-finished product again by the decentralization of conduit auxiliary in hole, later again by lateral steel in the present invention
The laying density of muscle and longitudinal reinforcement increases to predetermined density, further, longitudinal steel of banding steel cage in the step 5
After muscle and transverse steel to predetermined density, need to increase lateral fixed steel bars, the transverse direction fixed steel bars binding also according to scene
It is located at longitudinal reinforcement end in bottom hole.The program can adjust distributing position and the installation of reinforcing bar in time according to site operation state
Sequentially, the space for improving quality is increased compared with transferring steel reinforcement cage integral manufacturing after good again, so that steel reinforcement cage is more firm,
Improve construction quality.
3) end of conduit is equipped with symmetrical perforation in heretofore described step 2, and the perforation is passed through suitable for cable wire.It should
Scheme is conducive to withdrawal conduit in construction follow-up work, has further ensured construction quality and safety.
