Description
Technical field
The present invention relates to pile foundation construction field, specifically a kind of prefabricated pile stake core anti-blocking method.
Background technology
Typically in multilayer or high building project, through frequently with prefabricated tubular pile as pile foundation, and in construction often
There is prefabricated tubular pile stake core to be filled by foreign matter or soil, processing method is extremely complex, and for example stone is directly clamped among stake to some foreign matters
Inside core, it is impossible to rejected, manually can only be processed to using light instrument using equipment, and for example during earth excavation
A large amount of soil fill up stake core, secondary need to carry out borehole cleaning to stake core, waste a large amount of manpower and materials, and influence duration.
The content of the invention
It is an object of the present invention to provide preventing the method that stake core is filled by foreign matter during a kind of construction of prefabricated piles.
In order to achieve the above object, the present invention is realized in：
A kind of prefabricated pile stake core anti-blocking method, including
Step 1, the pre-buried otic placode in prefabricated pile, the otic placode are embedded in below pile end plate；
Step 2, before piling one plugging plate is connected by screw with pre-buried otic placode；
Step 3, progress piling work；
Step 4, after piling completes earth excavation to stake top absolute altitude, plugging plate is removed, and will prominent internal diameter otic placode gas cutting
Or tie.
The prefabricated pile stake core anti-blocking method, otic placode and prefabricated pile one-shot forming；Specifically, by ear before prefabricated forming pile
Plate is embedded in inside pile body in advance, and otic placode exposes the hole in advance fixed screw a core position and interior screw thread is completed, screw thread hole
It need to be matched with the closure board size of installation.
The prefabricated pile stake core anti-blocking method, plugging plate is combined with the screw hole internal thread deduction of points portion size of otic placode, sealed
Closure plate is U-shaped, and outside dimension must not exceed prefabricated pile stake core internal diameter size, and plugging plate adds spring shim and otic placode by screw
It is connected.
This anti-blocking method is easy to implement, with strong points, simple to operate, can prevent prefabricated pile from being applied in work progress and basis
Foreign matter saves the inconvenience that borehole cleaning is brought to the landfill of stake core during work, so as to reduce construction cost, saves the duration, raising is applied
Work efficiency rate, it is ensured that construction quality.

Embodiment
The present invention is further illustrated below by way of specific embodiment.
A kind of prefabricated pile stake core anti-blocking method, including；
As shown in figure 1, below the end plate 3 of prefabricated pile 2 pre-buried otic placode 1 totally 8, uniform branch in pile body internal diameter, otic placode 1 with it is pre-
During forming pile processed it is synchronous it is pre-buried pours completions, pre-buried exposed stake holes the inner of otic placode 1 need to beat internal thread hole 7, using M6 screws 5 and
Plugging plate is connected.
As shown in Fig. 2 otic placode 1 is processed into " 7 " font using the thick galvanized steel plain sheets of 3mm, 7 dozens of internal thread hole 6mm of revealed section, so as to
Subsequently it is connected with plugging plate.
As shown in figure 3, perforation plugging plate 4 and the engineering of otic placode 1 complete plugging effect, therefore plugging plate 4 is connected with otic placode 1
Screw hole 7 should be corresponded to strictly, uniform branch, and the diameter control of hole 8 is in 8mm, to ensure that stake reduces air during suppressing
Damage of the pressure to pile body, therefore uniformly beat diameter 10mm holes 6, the spacing 50mm of hole 6 in the plate face of plugging plate 4.
As shown in figure 4, the diameter D of plugging plate 4 is processed into U-shaped, sheet metal thickness 2mm according to actual size, the space of a whole page is according to spacing
50mm size uniforms perforate 6, the diameter 10mm of hole 6 alleviates stake holes inner air pressure, and the diameter of perimeter perforate 8 is not less than
8mm, and should being connected with otic placode internal thread hole branch, it is ensured that connection coincide.
As shown in Figure 5, Figure 6, pile driving construction is treated to designed elevation, and earth excavation is to bottom of foundation ditch, prefabricated pile end plate 3 is all
After exposed, stake in-core plugging plate 4 is removed, then picked the otic placode 1 of exposed stake core inner using gas welding cutting or corresponding tool
It is flat；So as to prevent piling or earth excavation process medium-and-large-sized hard thing or soil etc. from being clogged to stake holes.
