Abstract
The present invention relates to a variable supporting-plate club-footed embedded pile and a forming method thereof, which belongs to a pore-forming embedded prefabricated pile and a forming method thereof. The present invention mainly solves the problems of a filling pile of low bearing capacity and large slurry discharge. For solving the problems, the present invention has technical scheme that the variable supporting-plate club-footed embedded pile comprises a prefabricated reinforced bar concrete pile body, a grouting pipe preburied in the prefabricated reinforced bar concrete pile body and a plurality of variable supporting plates, wherein the variable supporting-plate club-footed embedded pile also comprises cement mortar; the variable supporting plates are arranged at the bottom of the pile body or in some position of the pile body; the cement mortar is injected into the periphery of the prefabricated reinforced bar concrete pile body and bodies of the variable supporting plates via the grouting pipe. In the forming method, 1, a reinforced bar concrete pile body is prefabricated; 2, a pile pore is drilled by a pore-forming machine; 3, annular conic supporting plates are squeezed at bottom of the pile pore or in some position of the pile pore; 4, the prefabricated reinforced bar concrete pile body is sunk into the pile pore; 5, the cement mortar is pressed into the bodies of the supporting plates and the periphery of the prefabricated reinforced bar concrete pile body. The present invention is mainly used for the civil engineering construction of building piling.
Description
One, technical field:
The present invention relates to a kind of variable supporting-plate club-footed embedded pile and forming method, it belongs to a kind of pore-forming and implants preformed pile and forming method thereof.
Two, background technology:
The bearing capacity of well-known ordinary concrete castinplace pile is low, and because during the in-site pouring concrete, pile quality is difficult to guarantee that sediment of the hole bottom is difficult for handling clean, so it exists and easily causes shortcomings such as the big and discharging mud amount of building settlement is big.
Three, summary of the invention:
The objective of the invention is to solve the technological difficulties that pouring pile bearing capacity is low, the discharging mud amount is big and provide a kind of and can guarantee pile quality, the variable supporting-plate club-footed embedded pile that makes it batch production and forming method.
The technical solution used in the present invention is:
This variable supporting-plate club-footed embedded pile, it comprise one by reinforcing bar and the concrete prefabricated steel bar concrete pile body that becomes, be embedded in Grouting Pipe in the concrete pile body and 1-5 cross section for the annular longitudinal section is leg-of-mutton variable supporting-plate, it is characterized in that: further comprising cement mortar; Variable supporting-plate is located at the bottom of pile body or the middle and lower part of pile body, and cement mortar is infused in the disk body of the periphery of prefabricated concrete pile body and variable supporting-plate by Grouting Pipe.
The forming method of above-mentioned variable supporting-plate club-footed embedded pile is finished by following step:
(1), prefabricated reinforced concrete pile body at first, and Grouting Pipe is embedded in the concrete pile body, make the stock inlet of Grouting Pipe stretch out the end face of concrete pile body, the grout outlet of Grouting Pipe stretches out the bottom surface of concrete pile body;
(2), in the position in needs piling hole, by the engineering design requirement with the boring machine hole of driving piles;
(3), use can be in the stake hole the squeezed or machinery that digs expansion in the bottom in stake hole or the middle and lower part in stake hole squeezed or dig that to expand into one or more cross sections be leg-of-mutton dish as the annular longitudinal section;
(4), prefabricated concrete pile body is sunk in the hole;
(5), with the slip casing by pressure machine by Grouting Pipe, cement mortar is pressed in the periphery of the disk body of variable supporting-plate and concrete pile body and promptly makes variable supporting-plate club-footed embedded pile.
Because the present invention combines squeezed, preformed pile stake core, post grouting process, and according to different soil layers a dish of several same diameter or a dish of different-diameter are set in same stake hole, the bearing capacity of pile foundation is improved, pile quality is guaranteed; Can eliminate pile bottom sediment or loosened soil and all inherent shortcomings of stake by slip casting, improve stake pedosphere face, make the soil body in the Zhou Yiding scope obtain reinforcing, therefore the present invention compares with background technology, have that bearing capacity height, stake do not have loosened soil an end, pile quality is easy to guarantee advantages such as economical with materials, reduction of erection time and minimizing blowdown.
Four, description of drawings:
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the A-A sectional drawing among Fig. 1.
Five, the specific embodiment:
The invention will be further described below in conjunction with drawings and Examples.
As depicted in figs. 1 and 2, variable supporting-plate club-footed embedded pile in the present embodiment, it comprise one by reinforcing bar with the concrete prefabricated steel bar concrete pile body 4 that becomes, be embedded in Grouting Pipe 1 and two conical variable supporting-plates 3 of annulus in the concrete pile body 4, wherein it also comprises cement mortar 2; Two variable supporting-plates 3 are located at the bottom of concrete pile body 4 and the middle part of concrete pile body 4 respectively, and cement mortar 2 is infused in the disk body of the periphery of prefabricated concrete pile body 4 and variable supporting-plate 3 by Grouting Pipe 1.
The forming method of above-mentioned variable supporting-plate club-footed embedded pile is:
(1), prefabricated reinforced concrete pile body at first, and Grouting Pipe is embedded in the concrete pile body, make the stock inlet of Grouting Pipe stretch out the end face of concrete pile body, the grout outlet of Grouting Pipe stretches out the bottom surface of concrete pile body;
(2), in the position in needs piling hole, by the engineering design requirement with the hole forming machine hole of driving piles;
(3), use can be in the stake hole squeezed prop shaping machine at the bottom in stake hole and the middle part in stake hole the squeezed conical variable supporting-plate of annulus that becomes two same diameters;
(4), prefabricated concrete pile body is sunk in the hole;
(5), with the slip casing by pressure machine by Grouting Pipe, cement mortar is pressed in the periphery of the disk body of variable supporting-plate and concrete pile body and promptly makes variable supporting-plate club-footed embedded pile.
Variable supporting-plate in the foregoing description can also only be established one, and its position is located at the bottom of concrete pile body.The conical variable supporting-plate of annulus (length of looking pile body is fixed) of 3-5 same diameter or different-diameter perhaps is set, and one of them is located at the bottom of concrete pile body, and all the other evenly are located at the middle and lower part of concrete pile body.
Squeezed machinery in the foregoing description method step 3 can also adopt and dig expansion formula machinery, digs in the stake hole and expands into variable supporting-plate.
If under certain condition, construction technology and equipment all can guarantee pile quality, and the prefabricated concrete pile body in the foregoing description also can adopt cast-in-situ concrete to implement, and variable supporting-plate and pile body promptly become one.
