The utility model discloses a multi-stage grouting concrete pouring pile, which comprises a pile body. A pile tail is arranged under the body, and the pile tail is fixedly connected with the pile body. The utility model can effectively solve the problems that the grouting pipe of the traditional grouting pile cannot be pulled out, the manufacture of the steel cage is difficult, and the adaptability to geological conditions is poor; the multi-stage grouting pile can be set at different positions according to the actual engineering geological conditions. The cement slurry expands the joints, stimulates the activity of ordinary concrete, and improves the performance of the pile body.

Description

Multistage grouting concrete castinplace pile
Technical field
The utility model relates to the pile foundation engineering field of civil engineering, and in particular, the utility model relates to a kind of multistage grouting concrete castinplace pile.
Background technology
At present, cast-in-place concrete pile is widely used in reinforcing soft ground.Due to the complexity of engineering geological conditions, conventionally need to reduce the impacts of factor on pile quality such as stake end loosened soil, sediment, mud skin, soil layer sudden change, thereby improve bearing capacity at stake end and pile body weakness injected water mud, reduce settling amount.At present, prior art adopt normally by Grouting Pipe colligation on reinforcing cage, cause fabrication of reinforcing cage difficulty, and Grouting Pipe cannot extract, can not reuse.Meanwhile, fixing slip casting position, also unable to do what one wishes when the conditions such as reply soil layer sudden change in advance, can not meet complex geological condition and more high-bearing capacity requirement.
Utility model content
The purpose of this utility model is to solve existing above-mentioned problem, and a kind of multistage grouting concrete castinplace pile is provided.
For realizing above object, the technical solution of the utility model is a kind of multistage grouting concrete castinplace pile, comprise pile body, it is characterized in that, described pile body external surface is provided with some troclias, described troclia is fixedly connected with pile body, and described pile body below is provided with a tail, and described stake tail is fixedly connected with pile body.Utilize the troclia on pile body, can reduce the impacts of factor on pile quality such as stake end loosened soil, sediment, mud skin, soil layer sudden change, thereby improve bearing capacity, reduce settling amount.
As preferably, the diameter of described troclia is greater than the diameter of pile body.The diameter of troclia is greater than the diameter of pile body, can effectively improve pile quality, also can prevent to a certain extent pile body sidesway.
As preferably, the diameter that is greater than pile body of described stake tail.
As preferably, described pile body inside is provided with reinforcing cage, and described reinforcing cage is fixedly connected with pile body.Pile body inside is provided with reinforcing cage, can increase the intensity of multistage cast-in-place concrete pile.
As preferably, described pile body is that the external surface of cylindrical, described troclia is arc.Pile body is cylindrical, and the external surface of troclia is arc, and such shape and structure can reduce the stress of multistage cast-in-place concrete pile and concentrate.
As preferably, troclia and stake tail solidify and form by the nano-silicon cement grout sclerosis of injecting.
The utlity model has following beneficial effect: the problems such as the Grouting Pipe that can effectively solve traditional grouting pile cannot be extracted, fabrication of reinforcing cage difficulty, geological conditions bad adaptability; Multistage grouting picket can arrange according to Practical Project geological conditions nano-silicon cement grout and expand node at diverse location place, excite the activity of ordinary concrete, improves pile body performance.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
1, reinforcing cage, 2, pile body, 3, troclia, 4, stake tail.
The specific embodiment
Below in conjunction with specific embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is further described:
Embodiment: multistage cast-in-place concrete pile (seeing accompanying drawing 1), comprise pile body 2, described pile body 2 external surfaces are provided with two troclias 3, described troclia 3 is fixedly connected with pile body 2, described pile body 2 belows are provided with a tail 4, described stake tail 4 is fixedly connected with pile body 2, the diameter of described troclia 3 is greater than the diameter of pile body 2, the diameter of described stake tail 4 is greater than the diameter of pile body 2, described pile body 2 inside are provided with reinforcing cage 1, described reinforcing cage 1 is fixedly connected with pile body 2, and described pile body 2 is that the external surface of cylindrical, described troclia 3 is arc.
The diameter of troclia is greater than the diameter of pile body, can effectively improve pile quality, also can prevent to a certain extent pile body sidesway, the diameter of stake tail is greater than the diameter of pile body, stability and the bearing capacity that can improve whole pile body, described reinforcing cage is fixedly connected with pile body.Pile body inside is provided with reinforcing cage, can increase the intensity of multistage grouting concrete castinplace pile, pile body is cylindrical, the external surface of troclia is arc, such shape and structure can reduce the stress of multistage grouting concrete castinplace pile and concentrate, in the present embodiment, stake hole length 15m, ground weak soil has sudden change at underground 7m and 11m place.The long 14.5m of reinforcing cage 1.Therefore a tail 4 is set at the underground 15m place stake end, at underground 7m and sudden change place of the 11m soil body, 2 expansion nodes 42 is set altogether.Troclia and stake tail solidify and form by the nano-silicon cement grout sclerosis of injecting, and in nano-silicon cement grout, the mass ratio of nano-silicon and cement is 1% to 5%.The problems such as the Grouting Pipe that can effectively solve traditional grouting pile cannot be extracted, fabrication of reinforcing cage difficulty, geological conditions bad adaptability; Multistage grouting concrete castinplace pile can arrange according to Practical Project geological conditions nano-silicon cement paste and expand node at diverse location place, excite the activity of ordinary concrete, improves pile body performance.
The above-mentioned specific embodiment is used for the utility model of explaining; rather than the utility model is limited; in the protection domain of spirit of the present utility model and claim, any modification and change that the utility model is made, all fall into protection domain of the present utility model.
