Abstract
The utility model discloses the circular deep foundation ditch space enclosing structure of a kind of discreteness pile body supporting, be characterized in that this deep footing groove enclosing structure is constructed by discrete stake fender body and inwall and top beam to form, described discrete stake fender body by the double castinplace pile arranged in triangle disposition with arrange high-pressure rotary jet grouting pile more and form; Described inwall to be arranged on inside discrete stake fender body and to thicken gradually with foundation depth; Described top beam is arranged on discrete stake fender body and inwall top.The utility model compared with prior art has vertical space enclosing structure flexible arrangement, good environmental adaptability, less to surrounding environment influence, operating efficiency is high, be particularly useful for surrounding enviroment complexity, underground obstacle is more and the soft foundation Circular Pit engineering that construction space requirement is higher, improves economic benefit of engineering and social benefit.
Description
Technical field
The utility model relates to building Underground Space Excavation technical field, is especially applicable to the circular deep foundation ditch space enclosing structure that the more and soft foundation of limited space of underground obstacle adopts the supporting of discreteness pile body.
Background technology
At present, the good diaphragm wall of Circular Pit engineering many employings continuity in Soft Clay, interlocking pile equicontinuity supporting structure system, foundation ditch inside adopts circular ring beam or circular inner liner wall as horizontal support system, to provide the Circular Pit construction operation space that inner large area is opened wide, play the three-dimensional effect of Circular Pit.Large-scale circular deep-foundation pit engineering is more at underground obstacle, and surrounding enviroment are when comparatively complex space is limited, if adopt the good continuity supporting and protection structure of globality, as space enclosing structure forms such as diaphragm walls, space enclosing structure construction may run into obstruction, causes the situation that circular space enclosing structure cannot close.
The construction adaptability of prior art is poor, when especially more at underground obstacle, foundation ditch surrounding enviroment complicated condition and limited space, cannot solve the closed-ended question of circular space enclosing structure.
Utility model content
The purpose of this utility model is the circular deep foundation ditch space enclosing structure of a kind of discreteness pile body supporting designed for the deficiencies in the prior art, adopt discrete castinplace pile as vertical supporting and protection structure, castinplace pile isosceles triangle is arranged, form inside and outside two circle pile bodies, arrange between stake and after stake and arrange high-pressure rotary jet grouting pile more, both the effect of soil stabilization had been played, again as water-stop curtain system isolation underground water, space enclosing structure automatically closes in pressurized situation, the circular pressurized space effect of effective performance discreteness pile body, guarantee supporting and protection structure stability and receive strength rationality, this structure effectively improves the engineering adaptability of Circular Pit under complicated environmental condition, good stability, soil excavation is convenient, excavation deformation is little with hole end resilience, operating efficiency is high, programming is fast, engineering cost is low.
The purpose of this utility model is achieved in that the circular deep foundation ditch space enclosing structure of a kind of discreteness pile body supporting, be characterized in that this deep footing groove enclosing structure is constructed by discrete stake fender body and inwall and top beam to form, described discrete stake fender body is by the double bored pile that arranges in triangle disposition and be arranged between Pile and many rows high-pressure rotary jet grouting pile after stake forms; In the foundation ditch that described inwall is arranged on discrete stake fender body side and body of wall thicken gradually with the degree of depth; It is that steel concrete is connected that described top beam is arranged on discrete stake fender body with liner coping and with discrete stake fender body and inwall.
The outermost two of described many row's high-pressure rotary jet grouting piles is arranged as closing continuously.
The utility model compared with prior art has vertical space enclosing structure flexible arrangement, good environmental adaptability, the double pile body that triangle disposition is arranged automatically closes in pressurized situation, the good pressurized effect having played circle shoring structure, less to surrounding environment influence, operating efficiency is high, and the construction space opened wide is large, be particularly useful for surrounding enviroment complexity, underground obstacle is more and the soft foundation Circular Pit engineering that construction space requirement is higher, improves economic benefit of engineering and social benefit.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the A-A sectional drawing of Fig. 1.
Detailed description of the invention
Accompanying drawings 1 ~ accompanying drawing 2, the utility model to be constructed with inwall 5 and top beam 7 by discrete pile body 1 and is formed, and described discrete stake fender body 1 is by the double bored pile 2 that arranges in triangle disposition and be arranged between bored pile 2 and many rows high-pressure rotary jet grouting pile 3 after stake forms; Described inwall 5 is arranged on inside the Circular Pit 4 that discrete pile body 1 encloses, and the degree of depth of its thickness of wall body oblong foundation ditch 4 excavation strengthens and thickeies gradually; Described top beam 7 be arranged on discrete pile body 1 and inwall 5 top and with discrete pile body 1 and inwall 5 for steel concrete is connected.Described outermost two arranges high-pressure rotary jet grouting pile 3 for closing continuously.
The utility model is construction like this: set the double bored pile 2 in triangle disposition according to the situation of underground obstacle, between the stake of then row hole drilling castinplace pile 2 outside and many row's high-pressure rotary jet grouting piles 3 of constructing after stake, high-pressure rotary jet grouting pile 3 is reinforcing between bored pile 2 and water-stop curtain, should ensure that outermost two arranges the continuous closure of high-pressure rotary jet grouting pile 3, form the fender body structure of complete Circular Pit 4, then construct top beam 7 successively excavation section by section inwall 5, inwall 5 successively thickeies until hole end absolute altitude with building from top to bottom with digging.
More than just be further described the utility model, and be not used to limit this patent, all be the utility model equivalence enforcement, within the right that all should be contained in this patent.
