Description
Technical Field
The invention relates to the technical field of buildings, in particular to an energy-saving rotary excavating pile structure.
Background
The traditional pile hole adopts manual excavation, the diameter is enlarged at the bottom of the manual hole digging pile, the pile is called a manual hole digging club-footed pile, and the pile is reliable in stress performance, does not need large-scale machine tools and equipment, is simple in construction operation process, can directly check the condition of a pile bottom rock-soil layer, is high in single-pile bearing capacity, does not have environmental pollution, and is relatively universal in various places. However, the pile hole has the following defects: the labor intensity in hole digging is high, the construction speed of a single pile is low, particularly, the safety is poor, and collapse and other dangerous situations are easy to occur. In order to overcome the defects, the rotary digging pile technology is widely applied.
Disclosure of Invention
The invention provides an energy-saving rotary excavating pile structure which can improve the stability of a soil layer in the rotary excavating process.
In order to achieve the purpose, the invention adopts the following technical scheme:
the utility model provides an energy-conserving stake structure of digging soon which characterized in that: including the stake pole and be located the reaming piece in the stake pole outside, reaming piece includes the edge the gasbag of stake pole axial extension and shrink, the gasbag lateral part is equipped with expansion plate, expansion plate surface is the same with the inboard surface shape in stake hole.
Preferably, the air bag is of a disc-shaped structure, and the expansion plates are a plurality of arc-shaped plates uniformly arranged along the circumferential direction of the air bag.
Preferably, the expansion plate is a polytetrafluoroethylene plate.
Preferably, the expansion plate is a stainless steel plate.
Preferably, the outer side of the pile rod is provided with an annular rib, the inner side of the air bag is provided with a fixed cylinder, and the inner side wall of the fixed cylinder is provided with a sliding groove matched with the annular rib.
Preferably, the upper end of the air bag is provided with a high-pressure air nozzle and is connected with an external inflating structure.
In summary, compared with the prior art, the invention has the advantages that: the air bag opens and closes to drive the expansion plate to move, and the soil layer or the mud wall protecting layer is extruded, so that the stability is improved, the collapse risk is reduced, and the subsequent placement of the reinforcement cage is facilitated.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is a structural sectional view of the present invention.
The reference numbers in the figures are as follows:
1. pile rod, 11 annular ribs, 2 hole expanding pieces, 21 air bags, 22 expanding plates, 3 fixed cylinders and 31 sliding chutes.
Detailed Description
The invention will be further elucidated with reference to an embodiment in the drawing.
As shown in fig. 1, the energy-saving rotary excavating pile structure comprises a pile rod 1 and a reaming part 2 located outside the pile rod 1, wherein the reaming part 2 comprises an air bag 21 extending and contracting along the axial direction of the pile rod 1, an expansion plate 22 is arranged on the side part of the air bag 21, and the surface of the expansion plate 22 is the same as the surface of the inner side of a pile hole. Inflation and deflation of the air bag 21 realize extrusion of the expansion plate 22 on the side wall of the pile hole, so that the stability of the soil loosening layer and the gravel layer on the upper layer can be improved, a hole expanding section is formed, falling soil is reduced, falling soil on the upper end can be accepted, the falling soil on the upper end is avoided falling to the bottom of the pile hole, subsequent cleaning work is reduced, influence on drilling work is avoided, or the mud protective wall is extruded so as to facilitate subsequent arrangement of a reinforcement cage.
The air bag 21 is of an annular disc-shaped structure, the cross section shape of the air bag is the same as that of the pile hole, and the expansion plates 22 are a plurality of arc-shaped plates uniformly arranged along the circumferential direction of the air bag 21. The expansion plate 22 is a polytetrafluoroethylene plate with a thickness of 0.5-1.0cm and a light weight, so that it has little influence on the shape of the airbag 21, is highly corrosion-resistant and highly lubricated. The expansion plate 22 can also be a stainless steel plate, and has high rigidity and good extrusion effect. The air bag 21 can be a continuous structure surrounding the pile rod 1, or can be a plurality of air bag 21 sections arranged around the pile rod 1, and expansion plates 22 are arranged on each section of the air bag 21.
The outside of stake pole 1 is equipped with annular rib 11, and the gasbag 21 inboard is equipped with solid fixed cylinder 3, and solid fixed cylinder 3 inside wall is equipped with the spout 31 with annular rib 11 complex. The fixing cylinder 3 is sleeved on the pile rod 1, can be of a hoop-shaped structure with two ends connected through bolts, is matched with a plurality of discontinuous air bag sections, can select whether to install the expansion mechanism or not according to needs, and can be taken down when not used. The cross section of the rib is square, the sliding groove 31 is embedded with the annular rib 11 to limit the air bag 21 to move up and down, and the air bag 21 can rotate along the annular rib 11 to extrude soil layers at different positions. The upper end of the air bag 21 is provided with a high-pressure air nozzle and is connected with an external inflating structure, and the high-pressure air nozzle is matched with an external air pump through a high-pressure air pipe to inflate the air bag 21.
The above description is only for explaining the present invention and making the present invention complete, but not limiting the present invention, and the skilled in the art can make modifications without inventive contribution to the present embodiment as required after reading the present specification, and these are all modifications without inventive contribution, but are protected by patent laws within the scope of the claims of the present invention.
