Abstract
Disclosed is an anchor-free deep cement sheet-pile wharf. The anchor-free deep cement sheet-pile wharf is technically characterized by comprising a cement sheet pile block composed of a cement sheet-pile, the cement sheet pile block is adjacent to an undisturbed soil layer in position, a steel sheet pile is arranged on the other side of the cement sheet pile block, a jet grouting pile is arranged between the steel sheet pipe and the cement sheet pile block, a concrete cover sheet connected with the steel sheet pile and the cement sheet pile block integrally is arranged at the top of the cement sheet pile block, a cover sheet extending column on one side of the concrete cover sheet is fixedly connected with the top of the steel sheet pile and connected to the top of the jet grouting pile, the top of the jet grouting pile is lower than that of the steel sheet pile, the bottom of the steel sheet pile is connected with the jet grouting pile, the other side of the steel sheet pile is connected with a jet grouting pile with the top located on the foundation excavation bottom surface, and the bottom of the steel sheet pile is located in medium sand layer. By the anchor-free deep cement sheet-pile wharf, for geological conditions of mucky soil, after sinking of the steel sheet pile is completed, reinforcement construction of a foundation on two sides of the wharf can be performed directly and synchronously, and engineering projects are constructed conveniently and rapidly.
Description
Technical field
The present invention relates to seashore harbour technical field, particularly a kind of without anchor deep-cement sheet-pile wharf.
Background technology
Conventional support engineering generally adopts the structures such as soil nail wall, Cement-soil Gravity enclosure wall, shaped steel cement mixing wall, steel sheet pile enclosure wall, reinforced concrete sheet pile enclosure wall, castinplace pile campshed enclosure wall and ground-connecting-wall to carry out pattern foundation pit supporting structure, and dock structure generally adopts gravity type quay, has the structures such as anchor sheet-pile wharf and long piled wharf.
Higher in groundwater table, if only adopt steel sheet pile to add the structure of anchorage system, steel sheet pile pile body stiffness does not meet the demands, and the construction period of Wharf Construction is urgent, so often have little time ground to reinforce, and cutting depth is 5～10m, closely fill out in the situation that silt soil strata is thicker, build the small-sized supporting and protection structure that goes out to transport harbour and sit end Wu Keng (foundation ditch), the construction of every supporting type and dock structure above, all need dig on a wide area, thereby peripheral structure is exerted an influence, in addition, the applicability of the construction of aforementioned every supporting type and dock structure, the convenient degree of constructing, construction period and economy are all not ideal enough.
Summary of the invention
In order to address the above problem, the invention provides a kind of without anchor deep-cement sheet-pile wharf.
A kind of without anchor deep-cement sheet-pile wharf, it is characterized in that: comprise the cement pile block being formed by cement pile, position next-door neighbour's original state soil layer of this cement pile block, the opposite side of cement pile block is provided with steel sheet pile, between steel sheet pile and cement pile block, be provided with rotary churning pile, the top of cement pile block is provided with steel sheet pile and cement pile block is connect for holistic concrete cover, and the top of a side cover plate extending column fixing connection steel plate stake of concrete cover is also connected to the top of rotary churning pile.
Further, the top of described rotary churning pile is lower than the top of steel sheet pile.
Further, the bottom of described steel sheet pile connects rotary churning pile, and the opposite side of steel sheet pile is connected with top and is positioned at the rotary churning pile of foundation excavation bottom surface.
Further, the distolateral of the concrete cover of described original state soil layer side is also provided with to the extending column of ground downward-extension.
Further, the bottom of described steel sheet pile is arranged in layer of sand.
Advantage of the present invention:
1, for the geological conditions of mucky soil, after steel sheet pile pile sinking completes, can according to actual needs, directly synchronously carry out harbour both sides foundation stabilization construction; Construction of Engineering Projects is convenient rapidly;
2, work progress is little to surrounding environment influence, occupation of land is few, is applicable to the construction environment of place narrow space;
3, supporting and protection structure is carried out excavation of foundation pit after completing, one-shot forming, and working procedure is simple;
4, avoided the adverse effect of anchorage system construction and excavation to all edge forming buildings;
5, the safety of structure self and neighboring buildings is guaranteed.
Brief description of the drawings
Fig. 1 is overall structure simplified schematic diagram of the present invention.
Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated; Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Embodiment 1
As shown in Figure 1, a kind of without anchor deep-cement sheet-pile wharf, comprise the cement pile block 1 being formed by cement pile, position next-door neighbour's original state soil layer 2 of this cement pile block 1, the opposite side of cement pile block 1 is provided with steel sheet pile 5, between steel sheet pile 5 and cement pile block 1, be provided with rotary churning pile 3, the top of cement pile block 1 is provided with steel sheet pile 5 and cement pile block 1 is connect for holistic concrete cover 7, what steel sheet pile 5 and the combining structure of cement pile block 1 were utilized cement pile block 1 forms gravity overall structure from feature great and that rigidity is large, the requirement of realization body structure stability against overturning, utilize the pile body shear resistance of steel sheet pile 5 to meet sliding stability and Circular Sliding stability requirement simultaneously, what concrete cover 7 had been removed steel sheet pile quaywall rear from draws anchor system structure, the top of one side cover plate extending column 6 fixing connection steel plate stakes 5 of concrete cover 7 is also connected to the top of rotary churning pile 3, the top of described rotary churning pile 3 is lower than the top of steel sheet pile 5, the bottom of steel sheet pile 5 connects rotary churning pile 3, the opposite side of steel sheet pile 5 is connected with top and is positioned at the rotary churning pile 3 of foundation excavation bottom surface 4, the bottom of steel sheet pile 5 is arranged in layer of sand.
Further, the distolateral extending column 6 being also provided with to ground downward-extension of the concrete cover 7 of described original state soil layer 2 sides.
Adopt technique scheme, for the geological conditions of mucky soil, after steel sheet pile 5 pile sinking complete, can according to actual needs, directly synchronously carry out harbour both sides foundation stabilization construction, Construction of Engineering Projects is convenient rapidly; Work progress is little to surrounding environment influence, occupation of land is few, is applicable to the construction environment of place narrow space; After completing, supporting and protection structure carries out excavation of foundation pit, one-shot forming, and working procedure is simple, has avoided the adverse effect of anchorage system construction and excavation to all edge forming buildings, and the safety of structure self and neighboring buildings is guaranteed.
