Description
Technical field
The present invention relates to technical field of civil engineering, particularly relate to the anti-floating of a kind of underground structure and structure, the resistance to plucking of above ground structure and the interior resistance to plucking muscle attachment structure of anti-floating stake 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 cast-in-situ concrete poured pilework, the external surface of pile body is lowered the frictional resistance between pile body and the foundation soil by one deck slurry coat method parcel, and the waste mud that construction produces has contamination to environment, and cost is higher.Usually because the existence of pile joint is prone to produce 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 be 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 is complicated, long in time limit.
The applicant had once proposed to be with in the external side of resistance to plucking muscle the patent application of anticorrosion metal tube; But find in actual the use; The metal tube of the external side of resistance to plucking muscle is carried with the resistance to plucking muscle and is difficult to connect together, because resistance to plucking muscle body is generally the cold rolled reinforcing bar of steel strand or wire rope class, and the anticorrosion metal tube is generally the steel pipe of hot rolling class; The steel pipe partial of cold rolled reinforcing bar and hot rolling welds, and can reduce the extraction-resistant behavior of cold rolled reinforcing bar.
