Description
Technical field
This utility model is related to the technical field of composite foundation, and particularly borehole thin-walled rubble is filled out core grouting pile and is combined ground
Base.
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 caisson is armored concrete or plain concrete is real
Heart stake, on the one hand leads to stake relatively costly because it is relatively large in diameter, and another aspect concrete coagulates consumption greatly and perfusion 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 borehole pouring concrete pile technology, provides a kind of reduction to apply
Work cost, improve that construction efficiency, construction noise are little, bending rigidity and anti-pressure ability are high, save rolled steel dosage 40%, save coagulation
The borehole thin-walled rubble of soil 60% fills out core slip casting pile composite foundation.
The purpose of this utility model is achieved through the following technical solutions：Borehole thin-walled rubble is filled out core grouting pile and is combined ground
Base, it includes stake holes, Grouting Pipe, armored concrete thin wall cylinder, armored concrete back cover and broken stone cushion layer, and stake holes is vertically arranged
And stake holes is arranged in ground, the bottom of stake holes is provided with armored concrete back cover, has been sequentially arranged in stake holes and from top to bottom
Multistage armored concrete thin wall cylinder, is provided with the Grouting Pipe of vertical setting in stake holes, Grouting Pipe is vertically arranged, the tube wall of Grouting Pipe
Go up and the length direction along Grouting Pipe is provided with multiple injected holes, filled rubble in armored concrete thin wall cylinder, described is broken
Stone bed pad layer is arranged at the top of armored concrete thin wall cylinder.
Described every adjacent segments 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 rubble fills out core layering vibration compacting.
Described injected hole is uniformly distributed in Grouting Pipe.
Described broken stone cushion thickness degree is 15cm ~ 30cm.
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 the restriction ability that rubble is filled out with core.
2）Fill rubble slip casting using borehole reinforced concrete core-tube composition is hollow, form the coagulation with some strength
Native pile body, increases bearing area.
3）Form large end face using borehole and amass stake bottom, and use armored concrete back cover, give full play to the pressure-bearing energy of foundation soil
Power.
4）Make full use of borehole retaining wall and form armored concrete thin wall cylinder, without using large type drill construction, reduce tradition
Bored concrete pile operation and time, technique is simpler, improves efficiency.
5）The armored concrete thin-walled cylinder pile being formed using borehole reinforced concrete core-tube, saves steel compared with total cross-section bored concrete pile
Timber-used amount 40%, saves concrete 60%.
6）Construction noise is little, and environmental conservation controllability is high.
