Abstract
The invention relates to a construction method for forming a foundation pit support through combining a concrete pile wall and jet grouting anchor piles and an anchor bar structural piece. According to the invention, the use of large amounts of reinforced concrete internal supports can be avoided during excavating the foundation pits in soft soil layers; hollow spaces in the internal supports are replaced with the jet grouting anchor piles so that convenience is brought to the earth excavation of the foundation pits and the civil construction of basements; and low manufacturing price and short project time are also obtained.
Description
Technical field
This technology belongs to fields such as building foundation, pattern foundation pit supporting structure, slope earth-retaining wall.
Technical background
Before; Mud and moisture enriching in the sand layer at weak shape; To execute like the Changjiang river triangle, Zhujiang River triangle and Efficiency in Buildings in Tianjin Area and to make weak soil layer pattern foundation pit supporting structure. anchor pole and soil nailing are unable to do what one wishes not to play the anchoring effect as contact pin in the thumbnail, and employing that therefore can only be passive is dangerous, cost is high, the city is had in the steel concrete piling wall ten of severe contamination and support support technologies, supports in old concrete piling wall ten reinforced concrete beams and makes pattern foundation pit supporting structure; Cause serious waste; Great collapse accident is annual constantly to be produced like Hangzhou Subway, Shanghai and Nanjing, the Guangzhou station of awaiting a subway, and this is caving-in bash, is to suffer from a kind of makeshift that does not have under other governing measure situation! Because of the anchor pole of routine, scholar's nail are placed restrictions on use in the silt soft scholar, can only be passive just use interior support, though often go out cave-in accident, also be last resort, create patented technology of the present invention to an above-mentioned difficult problem.,
The content of invention
Content of the present invention; Be to be the job practices and the dowel structural member that provide a kind of concrete piling wall and churning anchoring pile to be combined to form pattern foundation pit supporting structure; Make soft scholar's pattern foundation pit supporting structure, genuine supporting, slope earth-retaining wall supporting churning anchoring pile has substituted in the concrete beam and has supported; Guarantee the foundation ditch quality safety, can avoid the use of reinforced concrete beam again.
Goal of the invention
In order to realize the purpose of present technique, a kind of concrete piling wall of innovation and churning anchoring pile are combined to form pattern foundation pit supporting structure and dowel structural member, adopt following steps to realize the purpose of present technique.
1, one one kinds of concrete pile walls and churning anchoring pile are combined to form the job practices and the dowel structural member of pattern foundation pit supporting structure, it is characterized by: in the concrete piling wall, have row's churning anchoring pile at least, be inserted with muscle in the anchoring pile.
2, a kind of concrete piling wall according to claim 1 and churning anchoring pile are combined to form the job practices of the job practices of pattern foundation pit supporting structure, and it is characterized by said concrete piling wall is that stake, piling bar and underground concrete diaphragm wall are dug in drilled pile, manual work.
3, a kind of concrete piling wall of anchoring pile according to claim 1 and the churning anchoring pile job practices that is combined to form pattern foundation pit supporting structure, it is characterized by this churning anchoring pile is that the slip casting paddling process forms, and is that high-pressure rotary spraying method forms, and is that paddling process is combined into the churning method.
4, churning anchoring pile according to claim 1 is characterized by in this churning anchoring pile and is inserted with muscle, and muscle can be that steel strand also can be reinforcing bar and other metals and nonmetal rigid rib.
5, being inserted with muscle in dowel structural member according to claim 1 and the anchoring pile, it is characterized in that structural member is linked by steel wire and anchor slab to form. the muscle that is inserted with in the anchoring pile is metal ribs and the bamboo of rigidity such as reinforcing bar, steel wire, the nonmetal muscle of art etc.
Below in conjunction with accompanying drawing patented technology of the present invention is described,
Fig. 1 is the construction method step figure of this technology
As shown in the figure
1, at the bottom of ground 2, the foundation ditch 3, concrete piling wall 4, churning anchoring pile 5, weak soil body
Fig. 2 is the dowel structural member drawing of this technology
As shown in the figure
1, rigidity line 2, anchor plate.
