Abstract
An uplift-resistant pile structure consists of a jet grouting mixed pile body, uplift-resistant ribs and connecting parts. The jet grouting mixed pile body is formed by aid of a jet grouting mixing drill, the uplift-resistant ribs connected with a rib hanger are connected to a guide bit via special guide pipes after the reducing cement pile body is formed, and then are inserted into the pile body along the center of the jet grouting mixed pile; and after the uplift-resistant ribs are inserted in place, the guide pipes are retracted while the grout is jetted into the pile body. The uplift-resistant pile structure can be formed in a harder soil layer, and can also be formed in a softer soil layer, and has fine uplift-resistant resistance, lower cost and fast construction.
Description
Technical field
The utility model relates to technical field of civil engineering, particularly relates to the anti-floating of a kind of underground structure and structure, the resistance to plucking of above ground structure and the uplift pile structure of anti-inclination.
Background technology
The resistance to plucking of underground structure commonly used at present and structure anti-floating, above ground structure and the uplift pile structure of anti-inclination mainly are cast-in-place steel concrete pilework, precast reinforced concrete pile structure, precast prestressed concrete pilework and soil bolt structures.Because the cast-in-situ concrete pilework, the external surface of pile body is wrapped up by one deck slurry coat method, and the frictional resistance between pile body and the foundation soil is lowered, and the waste mud that construction produces has contamination to environment, and cost is higher.Usually because the existence of pile joint easily produces the possibility that uplift resistance lost efficacy, and the disturbance to the stratum is bigger in the work progress in addition, often building and the structure that close on is had a negative impact, cost is higher relatively for the precast reinforced concrete pile structure.Soil bolt makes the durability of anchor bar body be difficult to meet the demands because the topping quality of its body of rod and thickness are difficult to guarantee, the crack of topping is wayward.In order to improve the durability of resistance to plucking muscle body, in the steel concrete pilework,,, to cause material cost very high just often need reinforcement ratio is improved more can meeting the demands for the control crack.
In order to improve the frictional resistance between the soil body and the pile body, the post grouting process of employing or expanded bore pile structure are also arranged, but these all increase more construction cost, and construction technology complexity, long in time limit.
The utility model content
Technical problem to be solved in the utility model is, overcome technical problem and fault of construction that existing uplift pile structure exists, a kind of large diameter rotary jet stirring pile body is provided, insert no bonding steel strand and connector in the stake, apply pre-stretching force, make the rotary jet stirring pile body be in compressive state, can improve the uplift resistance of uplift pile, the crack of control pile body greatly, reduce cost.
In order to address the above problem the technical solution of the utility model is such:
A kind of uplift pile structure comprises a rotary jet stirring pile body, it is characterized in that, is embedded with resistance to plucking muscle body in the rotary jet stirring pile body, and resistance to plucking muscle front end is provided with one and hangs gusset, and the resistance to plucking muscle connects the extension gusset by connecting dop, hangs the gusset front end and also is provided with starter.Described resistance to plucking muscle body middle part is provided with locating support.
The rotary jet stirring pile body utilizes jet grouting and stirring drill tool to apply, after forming this pile body, many steel strand hanging gusset will be connected with, adopt special conduit, starter in the connection is sent in the pile body along the center of rotating spraying mixture pile and goes, insert put in place after, pumpback conduit on one side, on one side in pile body rotary jet grouting.
Described rotary jet stirring pile body is the cement soil body, and diameter is 150-1500mm;
Described resistance to plucking muscle body is the wherein a kind of of the many steel strand that do not have a bonding, reinforcing bar, steel pipe, section bar, is made up of the plastic cement pipe of common steel strand, reinforcing bar, steel pipe or section bar and isolation usefulness, is full of anticorrosion grease in the sebific duct;
Described connector, comprise resistance to plucking muscle body locating support, hang gusset, connect dop and starter.
Beneficial effect, a kind of novel uplift pile structure described in the utility model, substep applies and finishes, and both can form in comparatively hard soil layer, also can form in the soil layer of weakness such as mucky soil, quicksand and slity soil, and resistance to plucking is effective.

Described resistance to plucking muscle body 2 is the wherein a kind of of the many steel strand that do not have a bonding, reinforcing bar, steel pipe, section bar, and not having bonding steel strand reinforcing bar, steel pipe or section bar is to be made of steel strand reinforcing bar, steel pipe or section bar and plastic cement pipe.
Connector, comprise resistance to plucking muscle body locating support 3, hang gusset 4, connect dop 5 and starter 6.By locating support 3 resistance to plucking muscle body 2 is supported the location at a certain distance, dop 5 will be hung gusset 4 and resistance to plucking muscle body 2 links together with connecting, and starter 6 welds together with extension gusset 4.
In work progress, form rotary jet stirring pile body 1 earlier, in the rotary jet stirring pile body, resistance to plucking muscle body 2 and connector are inserted in wherein then by specialist tools, treat that slurries solidify the back and form uplift pile.Connector comprises locating support 3, hangs gusset 4, connects dop 5 and starter 6.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the manual just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
