Abstract
The utility model relates to a reinforced cast-in-place pile, which adopts a change section in a calabash string shape. Steel bars are inserted in a pile body. The steel bars adopt a preforming form or a field forming form. The utility model has the advantages of low cost, no vibration, no noise, convenient and quick construction and no overflow slurry pollution on a construction yard. The utility model can be used as bearing piles and composite foundations. The utility model can be used on the reiforcement and the leakage resistance of a soft foundation, the guard of a foundation ditch, the layer adding and the rectifying of a house, and the subsidence control of a building. The utility model can adopt flayash as pile body materials, which recycles waste and reduces costs.
Description
The stake of a kind of slip casting joint bar, relate to the stake structure and manufacturing technology.
Existing preformed pile and in situ pile mostly are that cross section is rectangle or circular normal cross section stake, this class stake is material of body of a pile cost height not only, and construction equipment complexity, must take bigger construction plant and space, common bearing peg as building, if they be used for that flabbiness ground strengthened, old housing reform is made, rectifying of leaned building or emergency dealing be just very uneconomical, even can't construct at the scene.
The utility model purpose is to provide a kind of engineering cost low, the slip casting joint bar stake of the variable cross-section of construction simple and fast and wide application.
The utility model is designed to cucurbit string shape, to add the frictional resistance between timber pile and foundation soil, improves the bearing capacity of stake.' cucurbit string ' number in the pile body and position are according to the length of stake and the design of soil property situation and determine the slip casting point.The utility model adopts grouting pile-forming equipment now to make in the foundation soil at the scene, pile body by slip casting from top to down with become ' cucurbit string ' shape to form at each slip casting point high-pressure slip-casting, globality and intensity in order to improve pile body are provided with some vertical reinforcements according to designing requirement in pile body.
The utility model has the advantages that cost is low, site construction technology is simple, friction, noiseless, nothing emit slurry to pollute.And applied range both can be used as bearing peg, can be used for again flabbiness ground strengthened, antiseepage, bracing of foundation pit, the correction of old foundations plinth, overbuilding story, building settlement control also can be used as composite foundation.The utility model can adopt flyash as material of body of a pile, both can turn waste into wealth, and can reduce cost again.
Accompanying drawing is the utility model embodiment.
Fig. 1. the utility model schematic diagram.
The utility model will be further described in conjunction with the accompanying drawings;
When the utility model carries out field fabrication, when adopting the slip casting from top to bottom of slip casting drilling rod to form pile body 1, carry out high-pressure slip-casting at each design slip casting point, the slurries that make this point to around diffuse into spherical, after having annotated by the slurry amount of designing requirement, the slip casting drilling rod is delivered to next slip casting point, repeat said process and finish until last slip casting point slip casting, at this moment whole pile body becomes cucurbit string shape 2.Extract the slip casting drilling rod after slip casting is finished, reinforcing bar 3 is inserted in the cucurbit string shape pile body, strengthen the globality and the intensity of cucurbit string shape pile body.Joint bar finishes, and slip casting joint bar stake field fabrication is finished.
Claims (1)
- The stake of a kind of slip casting joint bar is made of pile body (1) and reinforcing bar (3), it is characterized in that: pile body (1) is cucurbit string shape (2), is inserted with reinforcing bar (3) in the pile body.
