Abstract
The utility model discloses a kind of spiral grouting preformed pile, it comprises preformed pile body, stake side spiral grouting pipe, pile end grouting pipe, stake side spiral grouting pipe arm and the pile top of being with helical groove; Described helical groove is along preformed pile stake side screw arrangement; Described stake side spiral grouting pipe in the shape of a spiral, is placed in helical groove, and have many side direction spiral grouting pipe arms outside spiral grouting pipe, spiral grouting pipe is fixed in arm one end, and the other end is fixed on helical groove, and arm is horn-like; Described pile end grouting pipe is along preformed pile body central via arrangement, and upper end is placed in preformed pile, and this is external, and lower end is positioned at pile top, and tee piece is installed in lower end.This structure slip casting type preformed pile has vertical bearing capacity of single pile and horizontal bearing capacity is high, the advantage of applied range.
Description
Technical field
The utility model relates to building field preformed pile, especially a kind of can the spiral grouting preformed pile of slip casting.
Background technology
In pile foundation engineering, preformed pile is widely used in the middle of engineering construction as traditional pile foundation form, and it has transport, lifting is convenient, construction safety, quick, the advantages such as cost is low.The defect existed is: due to the restriction of pile driving pressure, and major diameter preformed pile is difficult to construction, and minor diameter preformed pile bearing capacity of single pile is not high; For PHC pile tube, because tube wall is too thin, horizontal bearing capacity is low.Therefore, the application of preformed pile in highrise building receives certain restriction.
Summary of the invention
The purpose of this utility model is to provide a kind of Vertical Bearing Capacity of Single Precast Pile and horizontal bearing capacity is high, the slip casting type preformed pile of applied range.
For realizing above object, the utility model spiral grouting preformed pile comprises preformed pile body, stake side spiral grouting pipe, pile end grouting pipe, stake side spiral grouting pipe arm, the pile top of band helical groove; Described helical groove is along preformed pile stake side screw arrangement; Described stake side spiral grouting pipe in the shape of a spiral, is placed in helical groove, and have many side direction spiral grouting pipe arms outside spiral grouting pipe, spiral grouting pipe is fixed in arm one end, and the other end is fixed on helical groove, and arm is horn-like; Described pile end grouting pipe is along preformed pile body central via arrangement, and upper end is placed in preformed pile, and this is external, and lower end is positioned at pile top, and tee piece is installed in lower end.
Described pile top comprises conical section and cylinder two parts, and cylinder is positioned at pile top upper end, lateral opening hole, is hollow body, and interior filling rubble, has space between rubble; The conical section being positioned at pile top lower end is solid.
Described its beneficial effect of arc groove groove face is the contact surface increasing preformed pile and slurries.
Described its beneficial effect of side direction spiral grouting pipe arm can be slurries provides pulp passage.
Described pile top can be made up of concrete or steel work, places the filling rubble in band space in pile top cylinder, and can provide passage for slurries flow out, rubble not easily fills overfill, with anti-extrusion pile end grouting pipe.
The construction sequence of the utility model spiral grouting preformed pile is: 1. place cleaning, surveying setting-out, true fixed pile; 2. this slip casting spiral preformed pile body of static pressure; 3. by slip casting around pile pipe to this preformed pile slip casting around pile; 4., after this preformed pile slip casting around pile completes, slip casting is carried out to this preformed pile stake end.
The utility model spiral grouting preformed pile has following beneficial effect:
Improve level and the longitudinal load-bearing power of preformed pile, compared with traditional preformed pile, pile side resistance and end resistance can be improved, and local stiffening effect can also be played for soft layer.
Accompanying drawing explanation
Fig. 1 is the utility model spiral grouting preformed pile schematic front view.
Fig. 2 is the utility model spiral grouting preformed pile schematic top plan view.
Reference numeral: preformed pile body 1, helical groove 2, stake side spiral grouting pipe 3, stake side spiral grouting arm 4, pile end grouting pipe 5, pile top 6 and pile top inner stuffing 7.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model spiral grouting preformed pile is described in further detail.
As Figure 1-Figure 2, the utility model spiral grouting preformed pile comprises preformed pile body 1, stake side spiral grouting pipe 3, stake side spiral grouting arm 4, pile end grouting pipe 5 and the pile top 6 of being with helical groove 2, places filler 7 in pile top.
Described stake side spiral grouting pipe 3 adopts steel pipe, implants in preformed pile body 1 by pre-buried mode, and described spiral grouting pipe arm 4 should be embedded in preformed pile with spiral grouting pipe 3 simultaneously, and slurries are entered by spiral grouting pipe, then flow out from spiral grouting pipe arm.
Described helical groove 2 is arranged along preformed pile outer wall uniform spiral shape, and described helical groove wall should carry out consolidation process, prevents stress from concentrating, shear failure, at preformed pile inside spin recess sidewall place's embedded bar or can adopt steel fibrous concrete.
Described pile end grouting pipe 5 is positioned at preformed pile body 1 central through hole, the exposed preformed pile end in one end, and the other end is implanted in pile top 6, end connecting tee, is convenient to slurries and flows out.
Described pile top 6 is divided into conical section and barrel portion, and conical section is solid, and can be made up of concrete or steel work, barrel portion is made up of steel work, is hollow body, and cylindrical sidewall perforate, can fill rubble 7 in cylinder.
