Description
Technical field
This utility model is related to the technical field of architectural engineering foundation pile construction, and particularly borehole thin-walled rubble fills out core slip casting
Stake.
Background technology
Caisson in current engineering is because of easy construction, construction is very fast, do not need heavy mechanical equipment, has strong adaptability
The advantages of, wider in the aspect range of application such as highway and civil buildings.Generally digging hole filling pile is armored concrete or plain coagulation
Native solid pile, on the one hand leads to stake relatively costly because pile body diameter is larger, and the big perfusion of another aspect amount of concrete and solidification need
Longer time to be consumed, is unfavorable for shortening construction period.Therefore, how to reduce while shortening construction period and be constructed into
This, be the problem that those skilled in the art need to solve.
Utility model content
The purpose of this utility model is to overcome the shortcoming of existing piling technique, provides a kind of reduction construction cost, shortening
The borehole that Finish time, construction noise are little, bending rigidity and anti-pressure ability are high, save rolled steel dosage 40%, save concrete 60%
Thin-walled rubble fills out core grouting pile.
The purpose of this utility model is achieved through the following technical solutions：Borehole thin-walled rubble fills out core grouting pile, and it includes
Stake holes, Grouting Pipe, armored concrete thin wall cylinder and armored concrete back cover, stake holes is vertically arranged, and the bottom of stake holes is provided with steel
Reinforced concrete back cover, stake holes is interior and has been sequentially arranged multistage armored concrete thin wall cylinder from top to bottom, and Grouting Pipe is arranged at reinforcing bar
In concrete thin-wall cylinder, in Grouting Pipe and the length direction along Grouting Pipe is provided with multiple injected holes, armored concrete thin wall cylinder
Inside fill core rubble.
Described every adjacent level armored concrete thin wall cylinder is connected with each other.
Described armored concrete back cover is connected with each other with bottom armored concrete thin wall cylinder.
Described Grouting Pipe is no less than two.
Described fills out core rubble layering vibration compacting.
Described filling out is filled with cement mortar between core rubble.
This utility model has advantages below：
1）Form the multistage armored concrete thin wall cylinder being sequentially connected with using borehole reinforced concrete core-tube it is ensured that bending resistance
Rigidity and anti-pressure ability and to the sidewise restraint filling out core rubble.
2）Hollow using borehole armored concrete thin wall cylinder composition fills rubble slip casting, is formed and has some strength
Concrete pile body, increases bearing area.
3）Amass stake bottom using the large end face that borehole is formed, and use armored concrete back cover, give full play to the pressure-bearing of foundation soil
Ability.
4）Make full use of borehole reinforced concrete core-tube and form thin-walled stake cylinder, without using large type drill construction, reduce and pass
System bored concrete pile operation and time, technique is simpler, improves efficiency.
5）The cylinder stake being formed using borehole reinforced concrete core-tube, saves rolled steel dosage 40% compared with total cross-section bored concrete pile, saves
Concrete 60%.
6）Pile-forming speed is fast, construction noise is little, and environmental conservation controllability is high.
