Description
Technical field
This utility model relates to a kind of instrument preventing dry operation borehole filling pile cage of reinforcement from installing off normal.
Background technology
In the construction of dry working system cast-in-situ bored pile, hole wall slump, soil stone fall into and steel reinforcement cage is installed off normal and caused steel
The problems such as tendon protective layer is too small always affect the key factor of construction quality and efficiency of construction.After pore-forming, steel reinforcement cage was sling
Owing to its swing arm is longer, quality is relatively big in journey, the amplitude of oscillation cannot be effectively controlled, and can clash into unavoidably when being seated to aperture and protect
Cylinder, causes collapse hole or aperture soil stone to fall into, and increases sediment thickness at the bottom of hole, causes actual hole depth not to be inconsistent with design requirement, and reinforcing bar is pacified
Put less than projected depth.Additionally, the swing laid of steel reinforcement cage and perpendicularity problem also can affect efficiency of construction, improve artificial become
This.

Further, the diameter of described retaining wall upper end is not less than 2 times of steel reinforcement cage diameter.
Further, four fixing beams of the equidistant vertical welding of bottom surrounding of described cylindric casing, described fixing beam
Length is not less than the 1/2 of the difference of the upper and lower bore of retaining wall.
The beneficial effects of the utility model are: rational in infrastructure, and tool making technique is simple, easy for installation, can effectively control
Steel reinforcement cage vibration problems in hoisting process, and can prevent aperture soil stone from falling at the bottom of hole, it is ensured that pile quality meets state's domestic discipline and family rules
Model and design requirement, repeatable utilization, reduce construction cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is top view of the present utility model.
In figure: retaining wall 1-1, cylindric casing 1-2, fixing beam 1-3, steel reinforcement cage 1-4, extravasating hole 1-5.
Detailed description of the invention
Below in conjunction with embodiment, the utility model will be further described.
A kind of instrument preventing from doing operation borehole filling pile cage of reinforcement installation off normal of the present utility model is mainly by retaining wall 1-
1, cylindric casing 1-2, fixing beam 1-3, steel reinforcement cage 1-4, extravasating hole 1-5 composition.
Described instrument includes retaining wall 1-1, cylindric casing 1-2, I-steel 1-3, steel reinforcement cage 1-4, extravasating hole 1-5；Described
Being provided with steel reinforcement cage 1-4 in cylindric casing 1-2, the outside of described cylindric casing 1-2 is provided with retaining wall 1-1, described retaining wall
1-1 is funnel-form, and the top of described retaining wall 1-1 is provided with extravasating hole 1-5；Fixing beam 1-3 it is provided with bottom described retaining wall 1-1.
Described fixing beam 1-3 is I-steel.
The diameter of described retaining wall 1-1 upper end is not less than 2 times of steel reinforcement cage 1-4 diameter.
The fixing beam 1-3 of the equidistant vertical welding of bottom surrounding four, described fixing beam 1-3 of described cylindric casing 1-2
Length not less than the upper and lower bore of retaining wall 1-1 difference 1/2.
In manufacturing process, determine funnel retaining wall 1-1 lower end diameter d, root according to the size in Pile Foundations Design drawing king-pile footpath
Retaining wall 1-1 and cylindric casing 1-2 wall thickness is selected, to ensure that this instrument is not affecting steel reinforcement cage 1-4 according to thickness of protection tier
Lay smoothly on the premise of installation.Retaining wall 1-1 upper end diameter D is not less than 2 times of steel reinforcement cage diameter, to guarantee that steel reinforcement cage is along leakage
Bucket slips into funnel in hole.Extravasating hole 1-5, in order to lift and to overflow slurry.Equidistant vertically in the bottom surrounding of cylindric casing 1-2
Welding four fixing beam 1-3, fixing beam 1-3 length is not less than 1/2D-d, to ensure that this instrument is in steel reinforcement cage installation process
Balance and stable.Cylindric casing 1-2 stretches into a length of 1m ~ 2m in hole.The welding of each component all uses full weld.In this practicality
In the installation process of new tool, should slowly stretch in hole, avoid touching hole wall as far as possible.This instrument should be disposed vertically, and works as hole
During ground out-of-flatness around, should be first by Land leveling bottom fixing beam 1-3, it is ensured that each fixing beam 1-3's is highly consistent.At reinforcing bar
In cage 1-4 installation process, by winching at the bottom of steel reinforcement cage 1-4 on retaining wall 1-1, steel reinforcement cage 1-4 is slowly put into hole along retaining wall 1-1
In, after steel reinforcement cage installs, i.e. carry out concreting.
A kind of instrument preventing dry operation borehole filling pile cage of reinforcement from installing off normal of the present utility model, rational in infrastructure, work
Tool processing technology is simple, easy for installation, can effectively control steel reinforcement cage vibration problems in hoisting process, and can prevent aperture soil
Stone falls at the bottom of hole, it is ensured that pile quality meets national regulation and design requirement, repeatable utilization, reduces construction cost.
The foregoing is only embodiment of the present utility model, not thereby limit the scope of the claims of the present utility model, every
Utilize equivalent structure or equivalence flow process conversion that this utility model description made, or be directly or indirectly used in other phases
The technical field closed, is the most in like manner included in scope of patent protection of the present utility model.
