Abstract
The invention provides an outer pile inner hole soil retaining flapper-type pile tip used for prestressed concrete pipe (PHC) pile sleeving construction. An inner PHC pile (2) is sleeved with an outer PHC pile (1). A plurality of positioning and guiding rings (3) are pre-buried in the inner wall of the outer PHC pile (1) in a spaced mode. The outer pile inner hole soil retaining flapper-type pile tip comprises the outer PHC pile and flapper baffles (6). The outer pile inner hole soil retaining flapper-type pile tip is characterized in that four hinge pin sleeves (4) are uniformly welded to the periphery of a pre-buried flange at the end of the pile head of the outer PHC pile (1); the four flapper baffles (6) are arranged, wherein the diameter of the flapper baffles (6) is equal to that of the outer PHC pile (1), and the four flapper baffles can be spliced to meet the dimension requirement for the inner diameter of the outer PHC pile (1); and hinge pins (5) are welded and fixed to the bottom ends of the flapper baffles so that the flapper baffles can be matched with the hinge pin sleeves (4), and each flapper baffle (6) can be opened downwards freely. The flapper-type pile tip has the advantages that the structure is simple, manufacturing is convenient, the outer pile can enter an inner hole in a soilless mode in the pile sinking process, the internal soil digging procedure of the outer pile is omitted, the inner pile can be piled smoothly in a sleeved mode, and the working efficiency is improved.

Technical field
The present invention relates to the reinforced concrete pipe pile in a kind of pile foundation engineering, specifically, be a kind of stud endoporus gear soil flapper-type pile top for the dress construction of PHC pile protection.
Background technology
PHC stake (reinforced concrete pipe pile) is the main method of construction of structures foundation bearing, is widely used. The pile sinking process of PHC stake mainly adopts crawler type piling machine hammer piling. In the test pile of the newly-built coal yard silo project of present Baosteel plant area, have employed the pile-type of timber pile inner hole sleeve paxilla, usual this pile-type is rarely employed in pile foundation engineering.
Construction is coaling silo project by Baosteel in Coal Stack Yard, the concrete silo 30 of newly-built diameter 24m, high 46m, wall thickness 450mm in two stockyards of E/F. In the design phase of pile foundation, design has carried out the test pile of 4 kinds of pile-type together with owner, determines final Pile Foundations Design scheme. The pile-type having a kind of test pile in Pile Foundations Design test pile scheme is diameter-variable pile test, require first to squeeze into the stud of 1000mm, stud length 10 meters, soil 10 meters deep in stud need to be drawn out, play the interior stake of 600mm again in stud inner sleeve, interior stake is long 57 meters, finally pours into C30 pea gravel concreten between interior stud, after maintenance 28 days, the horizontal bearing capacity of test pile. In this testing program will by stud in soil 10 meters deep draw out, self-evident its is taken a lot of work effort, delays the test duration.
The set piling construction of therefore known timber pile inner hole sleeve paxilla also exists above-mentioned all inconvenience and problem.
Summary of the invention
The purpose of the present invention, is in that to propose not make soil enter the stud endoporus gear soil flapper-type pile top for the dress construction of PHC pile protection in outer stake holes in a kind of work progress.
For achieving the above object, the technical solution of the present invention is:

Decile 4 joint pin axle sleeves of welding on the pre-buried circumference of flange of the outer pile head end of described PHC;
Thering is provided the flap valve baffle plate that 4 lobes are identical with PHC stud diameter, make 4 lobe flap valve baffle plates can piece together the internal diameter size of PHC stud, flap valve baffle plate bottom is welded and fixed bearing pin to coordinate with joint pin axle sleeve, and makes every lobe flap valve baffle plate freely to open downwards.
The stud endoporus gear soil flapper-type pile top for the dress construction of PHC pile protection of the present invention can also be further achieved by the following technical measures.
Being previously described for the stud endoporus gear soil flapper-type pile top of PHC pile protection dress construction, in the middle of wherein said flap valve baffle plate, one reinforcement of welding increases flap valve baffle plate intensity.
Being previously described for the stud endoporus gear soil flapper-type pile top of PHC pile protection dress construction, wherein said flap valve baffle plate is >=10mm steel plate.
Being previously described for the stud endoporus gear soil flapper-type pile top of PHC pile protection dress construction, wherein, the length of described joint pin axle sleeve is 50mm.
Being previously described for the stud endoporus gear soil flapper-type pile top of PHC pile protection dress construction, the length of wherein said bearing pin is 360mm.
After adopting technique scheme, the stud endoporus gear soil flapper-type pile top for the dress construction of PHC pile protection of the present invention has the advantage that
1, flapper-type pile top simple in construction, easy to make;
2, realize stud in pile sinking without soil enter endoporus, decrease the operation of soil digging in stud make interior stake smoothly overlap beat, improve work efficiency;
3, engineering cost is reduced, it is ensured that the schedule requirement of engineering.

Fig. 1 is the structural representation during stud endoporus gear soil flapper-type pile top use state of the embodiment of the present invention;
Fig. 2 is the bottom view of the stud endoporus gear soil flapper-type pile top of the embodiment of the present invention.
In figure: 1PHC stud, stake in 2PHC, 3 positioning and guiding rings, 4 pin sleeves, 5 bearing pins, 6 flap valve baffle plates, 7 stiffened panels.
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing thereof, the present invention is illustrated further.
Embodiment 1
The stud endoporus gear soil flapper-type pile top for the dress construction of PHC pile protection of the present invention, in 600mmPHC, stake 2 is sleeved in 1000mmPHC stud 1, and PHC stud 1 inwall pre-buried setting position guide ring 3, including PHC stud and flap valve baffle plate 6.
Structural representation during state is used referring now to the stud endoporus gear soil flapper-type pile top that Fig. 1, Fig. 1 are the embodiment of the present invention. As it can be seen, 4 joint pin axle sleeves 4 of decile welding on the pre-buried circumference of flange of described PHC stud 1 pile crown end, the length of joint pin axle sleeve 4 is 50mm.
The flap valve baffle plate 6 that 4 lobes are identical with PHC stud 1 diameter is provided, make 4 lobe flap valve baffle plates can piece together the internal diameter size of PHC stud 1, flap valve baffle plate bottom is welded and fixed bearing pin 5 to coordinate with joint pin axle sleeve 4, and the length of described bearing pin 5 is 360mm, and makes every lobe flap valve baffle plate 6 freely to open downwards. Fig. 2 is the bottom view of the stud endoporus gear soil flapper-type pile top of the embodiment of the present invention, the flap valve unfolding mode that where the dotted line signifies that stud endoporus gear soil flapper-type pile top is in use washed open by stake in PHC 2.
