Description
Technical field
This utility model relates to civil engineering soil body reinforcement technique field in situ, strong particularly to a kind of mini pile
Intercept water composite soil nailing wall.
Background technology
Pulling force produced by the soil body, external loads is only delivered in shallow soil layer by current existing soil nail wall, because of
This easily produces unstability and topples, and must carry out precipitation process when construction, thus increases construction volume, soil
Nail wall produces harmful effect to construction safety, quality, process, so such soil nail wall still has many local
Need to improve.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the purpose of this utility model is to provide a kind of mini pile strong
Intercept water composite soil nailing wall, and construction safety, quality get a promotion, and construction progress is accelerated.
In order to achieve the above object, the technical solution of the utility model is achieved in that
A kind of mini pile intercepts water by force composite soil nailing wall, including the row's churning being located at the supporting soil body 7 side in situ
Stake waterproof of man 1, rotary churning pile waterproof of man 1 stretches into bottom foundation ditch less than 11 1～2m, rotary churning pile waterproof of man
The opposite side of 1 is provided with plural mini pile 2, and mini pile 2 gos deep into bottom foundation ditch following 2～4m, former
On the supporting soil body 7 of position and horizontal plane angle becomes 10 °～15 ° intervals to arrange soil nailings 4 and prestressed anchor 3, in advance should
The end of power anchor pole 3 is locked on anchoring channel-section steel 5 through mini pile 2.
A diameter of the 250～400mm of described rotary churning pile waterproof of man 1.
The described bore column irrigating pile that mini pile 2 is diameter 200～300mm and its skeleton are I-steel, every
Spacing between mini pile 2 is 1～2m.
The surface 6 of described mini pile 2 is followed successively by ground floor concrete eight, geomembrane 9, linked network inside-out
The second layer concrete 10 of injection.
The described spiral that soil nailing 4 is diameter 70～120mm, the 0.5～1.2 of its a length of cutting depth
Times and spacing be 1～2m, cutting depth be more than 20m.
Described prestressed anchor 3 uses finish rolling deformed bar.
The beneficial effects of the utility model: safeguard stablizing of excavation slope from multiple angles, geomembrane,
Rotary churning pile water stopping curtain 1 effect of intercepting water combines with mini pile 2 support action；Soil nailing 4 superficial part soil stabilization
Effect is drawn to combine with prestressed anchor 3 deep anchor；After digging, a gear combines with advance support.Therefore, should
Utility model is applicable to the multiple soil layer of deep basal pit, especially to muck soil and cohesive soil, during construction can not precipitation,
Reduce construction volume and can also play good support action simultaneously.
Accompanying drawing explanation
Fig. 1 is this utility model overall structure schematic diagram.
Fig. 2 is the A portion enlarged drawing of Fig. 1.
Fig. 3 is the structural representation on the surface 6 of mini pile 2.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is made narration in detail.
With reference to Fig. 1, Fig. 2, a kind of mini pile intercepts water by force composite soil nailing wall, including being located at the supporting soil body 7 in situ
One row's rotary churning pile waterproof of man 1 on side, rotary churning pile waterproof of man 1 stretches into bottom foundation ditch less than 11 1～2m,
The opposite side of rotary churning pile waterproof of man 1 is provided with plural mini pile 2, mini pile 2 go deep into bottom foundation ditch with
Lower 2～4m, become 10 °～15 ° interval layout soil nailings 4 with horizontal plane angle and in advance should on the supporting soil body 7 in position
Power anchor pole 3, the end of prestressed anchor 3 is locked on anchoring channel-section steel 5 through mini pile 2.
A diameter of the 250～400mm of described rotary churning pile waterproof of man 1.
The described bore column irrigating pile that mini pile 2 is diameter 200～300mm and its skeleton are I-steel, every
Spacing between mini pile 2 is 1～2m.
With reference to Fig. 3, the surface 6 of described mini pile 2 be followed successively by ground floor concrete eight, soil inside-out
The second layer concrete 10 of work film 9, linked network injection, concrete uses C20, and bar-mat reinforcement uses ф 8 and grid
For 200mm × 200mm.
The described spiral that soil nailing 4 is diameter 70～120mm, the 0.5～1.2 of its a length of cutting depth
Times and spacing be 1～2m, cutting depth be more than 20m.
Described prestressed anchor 3 uses finish rolling deformed bar.
Operation principle of the present utility model is:
By geomembrane 9 at soil nailing 4, anchor pole 3, mini pile 2, rotary churning pile waterproof of man 1, surface 6 with
