Abstract
The utility model discloses a manually excavated pile structure which comprises a manual hole, a steel reinforcement cage and concrete. A concrete protective wall is arranged on the hole wall of the manual hole in a pouring mode, the lower portion of the manual hole is a hole pile expanded-foot, the diameter of the hole pile expanded-foot is larger than that of the upper portion of the manual hole, a head portion concrete protective wall is arranged on the side wall of the hole pile expanded-foot in a pouring mode, a plastic protective wall is arranged on the head portion concrete protective wall in an attached mode, the thickness of the lower end of each section of the concrete protective wall is smaller than that of the upper end of each section of the concrete protective wall, and a boss is formed at the upper end of the lower section of the concrete protective wall relative to the lower end of the upper section of the concrete protective wall. Due to the facts that each section of the concrete protective wall is manufactured to be of the structure that the inner diameter of the lower end is larger than that of the upper end, and the bottom of the manual hole is provided with the hole pile expanded-foot, and the structural strength of the whole pile is higher; the head concrete protective wall is arranged on the side wall of the bottom of the manual hole in a pouring mode and the plastic protective wall is arranged so that collapse of the side wall at the bottom of the manual hole can be prevented, secondary cleaning is avoided, and construction cost is reduced.
Description
Technical field
The utility model relates to construction engineering technical field, is specifically related to a kind of Manual excavated pile structure.
Background technology
Hand excavated pile refer to manpower cut the earth, in put the reinforced concrete pile of reinforcing cage, cast in situs.The general diameter of hand excavated pile is thicker, the thinnest also more than 800 millimeters, can carry the main structure body that floor is less and pressure is larger, applies at present commonplace.Stake above cushion cap is set, then with apron piece drawknot, link, the stressed of each is uniformly distributed, in order to support whole building.Because the problems such as construction plant sand layer thickness is large, water permeability is strong are avoided heat hole, easily cave in, have potential safety hazard.Cave in when preventing manual digging pile construction, cause security incident, conventionally can in manual digging pile construction process, set up steel casing, do man-made digging pile mould-pipe.But when hand excavated pile, the diameter up and down of each joint concrete guard wall is all identical at present, and wall thickness is also basic identical, but more down aperture is less, is unfavorable for like this constructing operation, and the structural strength of retaining wall also can be influenced.In addition, the bottom sidewall in artificial hole does not normally water retaining wall, if the time does not more build like this, and ponding in hole is easy to cause bottom hole wall collapse, then to carry out that secondary clears up be quite loaded down with trivial details work.
Utility model content
The utility model, for the defect of prior art, provides the Manual excavated pile structure that a kind of structural strength is higher, can avoid hole wall collapse.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of Manual excavated pile structure, comprise artificial hole, reinforcing cage and concrete, reinforcing cage is placed in artificial hole, concreting is in artificial hole, on the hole wall in artificial hole, built concrete guard wall, it is characterized in that: the bottom in artificial hole is hole pile enlarged foot, the diameter of hole pile enlarged foot is greater than the diameter on top, artificial hole, on the sidewall of hole pile enlarged foot, built head concrete guard wall, be close to head concrete guard wall and be provided with plastics retaining wall; The thickness of each joint concrete guard wall lower end is less than the thickness of upper end, and the upper end of next joint concrete guard wall forms a boss with respect to the lower end of a upper joint concrete guard wall, and boss is conducive to constructing operation.
Further, the bottom in described artificial hole is recessed arcuate bottom, and this structure can make hole stake more firm.
Further, described plastics retaining wall is provided with the permeable hole that runs through its sidewall.
Therefore further, the thickness of described plastics retaining wall is 10-15mm, and plastics retaining wall adopts high-intensity engineering plastics, and this plastics can be acted on behalf of metal, but cost is more much lower than metal, even if be placed in hole, do not take out also and can not increase too many cost.
The utility model makes by each is saved to concrete guard wall the structure that bottom diameter is greater than upper-end inner diameter, and pore-forming pile enlarged foot is done in the bottom in artificial hole, can make like this structural strength of whole hole stake higher; The bottom sidewall in artificial hole is built to head concrete guard wall and plastics retaining wall is set, so can prevent that bottom, artificial hole sidewall from caving in, avoid secondary cleaning, reduce construction cost.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is plastic protective wall construction schematic diagram.
In figure, 1 is reinforcing cage, and 2 is hole pile enlarged foot, and 3 is concrete guard wall, and 4 is head concrete guard wall, and 5 is plastics retaining wall, and 6 is boss, and 7 is arcuate bottom, and 8 is permeable hole.
The specific embodiment
In the present embodiment, see figures.1.and.2, described Manual excavated pile structure, comprises artificial hole, reinforcing cage 1 and concrete, and reinforcing cage 1 is placed in artificial hole, and concreting, in artificial hole, has been built concrete guard wall 3 on the hole wall in artificial hole; The bottom in artificial hole is hole pile enlarged foot 2, and the diameter of hole pile enlarged foot 2 is greater than the diameter on top, artificial hole, has built head concrete guard wall 4 on the sidewall of hole pile enlarged foot 2, is close to head concrete guard wall 4 and is provided with plastics retaining wall 5; The thickness of each joint concrete guard wall 3 lower end is less than the thickness of upper end, and the upper end of next joint concrete guard wall 3 forms a boss 6 with respect to the lower end of a upper joint concrete guard wall 3, and boss 6 is conducive to constructing operation.
The bottom in described artificial hole is recessed arcuate bottom 7, and this structure can make hole stake more firm.
Described plastics retaining wall 5 is provided with the permeable hole 8 that runs through its sidewall.
The thickness of described plastics retaining wall 5 is 10-15mm, and plastics retaining wall 5 adopts high-intensity engineering plastics, and this plastics can be acted on behalf of metal, but cost is more much lower than metal, even if be therefore placed in hole, do not take out also and can not increase too many cost.
Below the utility model is described in detail, the above is only the preferred embodiment of the utility model, when not limiting the application's practical range, be allly according to the application's scope, to do impartial change and modify, all should still belong in the utility model covering scope.
