Description
Technical field
The utility model belongs to geotechnical engineering field, and in particular to a kind of resistance to plucking structure using napiform root type uplift pile.
Background technique
Uplift pile basis is a kind of important pattern in building basis, it is widely used in transmission line foundation, towering builds
(structure) builds object basis, wind power foundation, communication tower basis, pond, civil air defense constructions and installations and basement anti-floating.Traditional resistance to plucking structure master
There are uplift pile, buried raft foundation, upright Pulling-Resistant Anchor Rod, enlarged footing uplift pile etc..In general cost is high, and some need is big
Type construction equipment, some anchor bolt supports provide the disadvantages of withdrawal resistance is smaller.
Summary of the invention
Purpose of the utility model is to solve defect existing in the prior art, a kind of easy construction and energy are provided
The structure for greatly reducing rock-bolt length, increasing withdrawal resistance.
In order to achieve the above object, the utility model provides a kind of resistance to plucking structure, including top foundation platform, is set to base
Several uplift piles below plinth cushion cap and it is embedded in the component that superstructure is connected in foundation platform；Wherein, foundation platform
Using cylindrical reinforced concrete cushion cap；Uplift pile be it is multiple, be along the circumferential direction distributed in below foundation platform；Uplift pile uses
Napiform root type anchor pole, including lower end anchor bar body and upper end anchor pole muscle, the bottom end of lower end anchor bar body it is spherical in shape；Lower end anchor bar body protrudes into base
Below plinth cushion cap, and length is not less than 4 times of foundation platform diameter；Upper end anchor pole muscle is inserted into foundation platform and length is anchor pole
35 times of muscle diameter.
Further, the spherical diameter of uplift pile bottom end is 3-4 times of lower end anchor bar body diameter.
Further, lower end anchor bar body is tilted towards outer arrangement, and tilt angle and plumb line are in 12-17 °；Upper end anchor pole muscle hangs down
Directly protrude between the reinforcing bar in foundation platform.
Further, uplift pile is equipped with three or more, and the spacing between adjacent upper end anchor pole muscle is not less than lower end anchor pole
10 times of body diameter.
The utility model has the advantage that compared with prior art
It had both increased the soil body in conjunction with the diagonally disposed of anchor bar body using the anchor structure that napiform root type designs and had rubbed to anchor pole
Resistance, and strengthen the withdrawal resistance of anchor bar body itself；Combined powerful resistance to plucking is formed by several ball root type anchor poles and cushion cap
Stress system overcomes traditional resistance to plucking structure deficiency, there is the advantages that at low cost, easy construction, short time limit, has good economic effect
Benefit, social benefit.
A point feature high using superficial part crust layer shearing strength can make full use of using this resistance to plucking structure simultaneously, provide
Very big withdrawal resistance, instead of costly uplift pile；Conventional anchor supporting body is substituted using expanding anchor bolt support in construction,
Greatly improve anchor bar body itself withdrawal resistance.Compared with traditional uplift pile, large scale equipment, easy construction, short time limit are not needed.

Specific embodiment
The utility model is described in detail with reference to the accompanying drawing.
As shown in fig. 6, the utility model resistance to plucking structure include top foundation platform 2, it is several below foundation platform
Root uplift pile and the component 3 for being embedded in connection superstructure in foundation platform.Wherein, foundation platform 2 uses cylindrical reinforcing steel
Concrete bearing platform.Uplift pile is multiple (6 are equipped in the present embodiment), is along the circumferential direction distributed in below foundation platform；Resistance to plucking
Stake uses napiform root type anchor pole 1, including lower end anchor bar body 11 and upper end anchor pole muscle 12, and the bottom end of lower end anchor bar body expands shape spherical in shape
At bottom napiform root 13.Lower end anchor bar body 11 protrudes into the lower section of foundation platform 2, and length is not less than 4 times of foundation platform diameter；On
It holds in the insertion foundation platform 2 of anchor pole muscle 12 and length is 35 times of anchor pole muscle diameter.
Specific construction process is as follows, in conjunction with shown in attached drawing 1 to 6:
(1) certain depth foundation trench 4 is excavated in below ground；
(2) drilling machine bores and plumb line is at the hole at 15 ° of (12-17 °) angles, and bore dia d=150mm is drilled into depth and is not less than
