The technical scheme that the utility model provides is: described a kind of hollow pile of civil engineering works, comprise pile body, be arranged on concrete enlarged footing bottom pile body and be arranged on the gripper shoe that pile body top extends outwardly, described pile body from inside to outside comprises steel cylindrical tube successively, reinforced concrete structure layer, flexible material packed layer, cushion coat and layer of concrete, reinforced concrete structure layer is coated on the outer wall of steel cylindrical tube, described cushion coat is made up of two pieces of semicircle protection steel discs, gap is provided with between the interface of two pieces of semicircle protection steel discs, and elastic body is provided with in gap, flexible material packed layer is filled between protection steel disc and reinforced concrete floor, described layer of concrete is coated on the external surface of protection steel disc.
The utility model is technical scheme preferably: be vertically provided with at least one long through-hole in described layer of concrete, and described long through-hole runs through whole layer of concrete from top to bottom.
The utility model is technical scheme preferably: described flexible material packed layer is that rubber layer strengthened by polythene material layer or polypropylene material or butyl material layer or fiber.
The utility model is technical scheme preferably: described gripper shoe circular base slab, and between gripper shoe and pile body, be provided with polylith fix muscle, polylith is fixed muscle and distributed ringwise along circular base slab.
The utility model is technical scheme preferably: described long through-hole has four, and four long through-holes are arranged in layer of concrete uniformly.
The utility model is technical scheme preferably: described fixing muscle has four pieces, and four pieces of fixing muscle are equally spaced.
The layer of concrete that the utility model comprises inner steel pipe at pile body and is coated on outside steel pipe, protection steel disc is outside equipped with at layer of concrete, the effect of protection can be played to concrete reinforcement layer, the extruding force of elasticity physical efficiency between two block protection steel discs to protection steel disc radial direction plays the effect of buffering, flexible material between protection steel disc and concrete reinforcement layer also can compensator or trimmer pressure, therefore strong, solid, the long service life of anti-pressure ability of the present utility model; The top of layer of concrete is provided with the gripper shoe extended towards radial direction, and gripper shoe increases the contact area with supported object, improves support effect; Concrete enlarged footing improves load-carry duty of the present utility model.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is for A-A in Fig. 1 is to schematic diagram.
In figure: 1-pile body, 1-1-steel cylindrical tube, 1-2-reinforced concrete structure layer, 1-3-flexible material packed layer, 1-4-cushion coat, 1-5-layer of concrete, 2-concrete enlarged footing, 3-gripper shoe, 3-1-fixing muscle, 4-elastic body, 5-long through-hole.
Detailed description of the invention
Below in conjunction with accompanying drawing, book is further illustrated to the utility model.A kind of hollow pile of civil engineering works as shown in Figure 1 comprises pile body 1, be arranged on concrete enlarged footing bottom pile body 12 and be arranged on the gripper shoe 3 that pile body top extends outwardly, the gripper shoe 5 at the top of layer of concrete 4 is circular, end face along pile body 1 stretches out, increase the contact area with supported object, improve support effect, between gripper shoe 3 and pile body 1, be provided with polylith fix muscle 3-1, fixing muscle is skewed, one end is connected to the bottom surface of gripper shoe 3, the other end is connected to the outer wall of pile body 1, ordinary circumstance arranges four pieces of fixing muscle 3-1, four pieces of fixing muscle are equally spaced ringwise along circular base slab.Described concrete enlarged footing 6 is after stake pore-forming, and adopt machinery in bottom or manually carry out reaming, then concreting forms enlarged footing, and its shape is indefinite, and the bottom of volume ratio pile body 1 is large, improves the load-carry duty of whole pile body.
