Description
Technical field
The invention belongs to taper pile construction field in architectural engineering, more particularly to a kind of high inclination-angle taper pile steel reinforcement cage decentralization is applied
Work method.
Background technology
With developing rapidly for domestic and abroad bridge technology, multiarch bridge, Deck Arch Bridges, steel arch bridge etc. possess have landscape,
The bridge structure form for meeting landform requirement is arisen at the historic moment, and not only embodies the design level of designer, is also to different types of rridges
A kind of checking of construction method.It is related to the Engineering Projects of taper pile more in Arch Bridge Construction, taper pile is also relatively universal under water, it is mostly big straight
The taper pile in footpath, 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 for the taper pile design of minor radius, High angle, both at home and abroad without ripe construction technology and equipment, more using excavated by manual work
The construction method in hole ensures the quality and safety of construction, but there is the disadvantage of many quality controls in work progress, because
The special construction principle of taper pile, and influenceed 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, in addition to carrying out advance support measure, also
Needs avoid the generation of some quality, security incident 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, because of the stake holes of High angle, ensure the installation effectiveness and quality of steel reinforcement cage, while ensuring that the thickness of protective layer is uniform simultaneously
Ensure the safety problem of work progress, be the practical problem that technical staff faces at the scene.
The content of the invention
The technical problems to be solved by the invention are：A kind of construction method of high inclination-angle taper pile steel reinforcement cage decentralization is provided, is carried
The efficiency of work progress high, quality and safety.
In order to solve the above-mentioned technical problem, the invention discloses a kind of construction method of high inclination-angle taper pile steel reinforcement cage decentralization,
Preamble work including perforate, laying bar-mat reinforcement, erection steel arch-shelf and gunite concrete, it is further comprising the steps of：

Step 4：Steel reinforcement cage semi-finished product are welded in by temporary weld steel bar welding pad is reserved on steel arch-shelf；
Step 5：The longitudinal reinforcement and transverse steel of banding steel cage, predetermined density is increased to by laying density.
Further, conduit is hollow steel pipe in the step 2, and its external diameter is identical with the thickness of steel bar cage protecting layer, institute
It is steel reinforcement cage outward flange to the default spacing between steel arch-shelf inward flange to state steel bar cage protecting layer.
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 laterally fixed reinforcing bar according to scene, the laterally fixed reinforcing bar colligation is located at longitudinal reinforcement end in bottom hole.
Further, check on the quality it is qualified after, extract out conduit.
Further, end of conduit is provided with symmetrical perforation in the step 2, and the perforation is suitable to cable wire and passes through.
Compared with prior art, the present invention can obtain following technique 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 need not be complete in the present invention
Steel reinforcement cage is simultaneously installed in laying in Quan Kong, nor by steel reinforcement cage integral manufacturing it is good after transfer again, the program is on the one hand, and complete
Steel reinforcement cage is laid and installed in hole compared to improve installation effectiveness and quality；On the other hand with by steel reinforcement cage integral manufacturing it is good after
Transfer again compared to improve installation quality and safety because the good steel reinforcement cage overall weight of integral manufacturing is too heavy, loop wheel machine handling and
There is very big potential safety hazard in decentralization process, there is recessive danger to operating personnel and other construction equipments；And first by steel reinforcement cage
Be fabricated to semi-finished product aids in decentralization to the method in hole by conduit again, and conduit has ensured installation effectiveness, while ensure that 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 conduit auxiliary decentralization to hole in the present invention, afterwards again by horizontal steel
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 laterally fixed reinforcing bar, the laterally fixed reinforcing bar colligation always according to scene
Longitudinal reinforcement end is located in bottom hole.The program can in time adjust distributing position and the installation of reinforcing bar according to site operation state
Sequentially, be increased compared with being transferred again after steel reinforcement cage integral manufacturing is good and carry high-quality space so that steel reinforcement cage is more consolidated,
Improve construction quality.
3) end of conduit is provided with symmetrical perforation in heretofore described step 2, and the perforation is suitable to cable wire and passes through.Should
Scheme is conducive to extracting conduit out in construction follow-up work, has further ensured construction quality and safety.
