Description
Technical field
The utility model belongs to constructional materials design field, is specifically related to a kind of high-bearing capacity pile tube steel shoe.
Background technology
General building place shallow layer foundation plinth of working as is weaker, can not meet the requirement of building to bearing capacity of foundation soil, when being not suitable for again taking artificial foundation's Reinforcement Measures, or when adopting artificial foundation to reinforce uneconomical, considers pile foundation.Shoe is the type belonging to pile top, and materials material is steel plate material, is welded on construction pile tube foremost, is arranged in pipe pile head when pile tube sinking construction, rise and guide and plugging action.
Stake static pressure construction is a kind of process for sinking stake be pressed into static pile press in soil, static pressure construction has noiseless, friction, thing impact force, stake factorial praluction quality feature more intuitively, but in current production technology, its steel shoe adopted is the steel pipe that a diameter is identical with pile tube internal orifice dimension, and the bearing capacity of this steel shoe is restricted.
Utility model content
The purpose of this utility model is for deficiency of the prior art, provides a kind of high-bearing capacity pile tube firm shoe, easy construction, economical reliable.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of high-bearing capacity pile tube steel shoe, described steel shoe is arranged at the front end of pile tube, comprise steel shoe body, it is characterized in that: described steel shoe body is made up of the hollow cylinder of two sections of different-diameters, comprise the first paragraph steel shoe of minor diameter and large diameter second segment steel shoe, described first paragraph steel shoe is arranged at the upper end of second segment steel shoe, and the sidewall of first paragraph steel shoe is provided with slip casting duct; Described second segment steel shoe diameter is greater than first paragraph steel shoe diameter 8 ~ 10cm, and its diameter equals the diameter of pile tube.
Described steel shoe also comprises slip casting pouch and grouting pipe; Described slip casting pouch is arranged at the periphery of first paragraph steel shoe, is fixedly connected with first paragraph steel shoe, and slip casting pouch and first paragraph steel shoe form slip casting chamber; Described grouting pipe connects slip casting pouch.
Further, described slip casting pouch two ends are fixed on first paragraph steel shoe by clip, and described clip is the end to end circulus of mating with first paragraph steel shoe, and these clip head and the tail are provided with screw, are fastened by bolts.
Further, described grouting pipe is L-type structure, one end of grouting pipe to be arranged in slip casting runner reserved in pile tube or be arranged at inside pile tube, the other end, through the slip casting duct of first paragraph steel shoe sidewall, extends in the chamber between slip casting pouch and first paragraph steel shoe.
The beneficial effects of the utility model:
1, pile tube steel shoe structure of the present utility model is simple, and easy to make, cost is low, economic use;
Slip casting bag bag is set outside the steel shoe 2, passed through, in slip casting pouch, is injected the cement paste of certain water/binder ratio by grouting pipe, slip casting pouch is strutted, strengthen bearing capacity.
Accompanying drawing explanation
Fig. 1 is the structural representation of steel shoe of the present utility model.
Fig. 2 is steel shoe of the present utility model and pile body connection diagram.
Detailed description of the invention
Below in conjunction with specific embodiment, the technical solution of the utility model is elaborated.
Refer to Fig. 1 and Fig. 2, for a kind of high-bearing capacity pile tube steel shoe, this steel shoe is arranged at the front end of pile tube, comprise steel shoe body, this steel shoe body is made up of the hollow cylinder of two sections of different-diameters, comprise the first paragraph steel shoe 1 of minor diameter and large diameter second segment steel shoe 2, first paragraph steel shoe 1 is arranged at the upper end of second segment steel shoe 2, and the sidewall of first paragraph steel shoe 1 is provided with slip casting duct 3; Second segment steel shoe 2 diameter is greater than first paragraph steel shoe 1 diameter 8 ~ 10cm, and its diameter equals the diameter of pile tube.
Steel shoe also comprises slip casting pouch 4 and grouting pipe 5; Slip casting bag 4 bags is arranged at the periphery of first paragraph steel shoe 1, slip casting bag 4 bags is arranged between first paragraph steel shoe 1 and forms slip casting chamber, its two ends of slip casting bag 4 are fixed on first paragraph steel shoe 1 by clip 6, clip 6 is the end to end circulus of mating with first paragraph steel shoe, these clip head and the tail are provided with screw (for drawing in figure), are fastened by bolts.
Grouting pipe 5 connects slip casting pouch, this grouting pipe 5 is L-type structure, one end of grouting pipe 5 to be arranged in slip casting runner reserved in pile tube or be arranged at inside pile tube, the other end, through the slip casting duct 3 of first paragraph steel shoe 1 sidewall, extends in the slip casting chamber of slip casting pouch 4.
High-bearing capacity pile tube steel shoe of the present utility model injects the cement paste of certain water/binder ratio in slip casting pouch 4 by grouting pipe 5, slip casting pouch strutted, and strengthens bearing capacity.
