Each tapered concrete pile comprises a pile body and a pile shoe, wherein the areas of the two ends of each pile shoe are unequal, a steel plate is arranged on the top of the end, with the smaller area, of each pile shoe, the top of each pile shoe is completely covered with the corresponding steel plate, the end, with the larger area, of each pile shoe and the corresponding pile body are connected into a whole, U-shaped rebars are evenly arranged on the outer walls of the pile bodies, two to four sets of U-shaped rebars are evenly arranged along the cross sections of the pile bodies, the anchoring ends of the U-shaped rebars are fixedly arranged in the pile bodies, notches of the U-shaped rebars face the pile bodies respectively, the separation distance between every two adjacent sets of U-shaped rebars in the longitudinal direction ranges from 0.5 m to 0.8 m, the distance between each U-shaped rebar and the top of the corresponding pile body is 0.3 m, and the U-shaped rebars of every two adjacent tapered concrete piles are bound through stirrups so that every two adjacent tapered concrete piles can be connected together and the foundation for the tapered concrete piles can be formed. According to the foundation for the tapered concrete piles, the pile shoes are of a footpace shape, the pile bodies are effectively prevented from tilting and sinking, the number of foundation treatment working procedures on the site is reduced, and construction is easy.
Description
Technical field
The utility model belongs to the shallow layer soft soil foundation treatment technology of civil engineering, is specifically related to a kind of concrete tapered pile basis.
Background technology
In recent years; in view of pile foundation can effectively suppress sedimentation, controls differential settlement and can realize the advantage of high-quality, standardization and large-scale production, the each side such as little, of many uses affected by environment; be widely used in building building construction on deep mud and saturated soft clay foundation, it has broad application prospects in China.But existing pile foundation is all generally to position by raft formula aperture plate (netted welded reinforcement), it needs a large amount of steel, and construction cost is high; It need to connect into entirety by the dowel of raft formula connection network and each piece, and the coherence request of the arrangement to each piece is higher, and difficulty of construction is large; In the time that pile body is settled, the breakage of shoe need to fill out rubble or rammed subgrade and prevent from pressing down pile body on-the-spot shallow layer soft soil time, working procedure complexity.Therefore, be necessary to study one both economical, working procedure easy pile foundation again.
Summary of the invention
The limitation problems such as the purpose of this utility model is to provide a kind of concrete tapered pile basis, while solving existing pile foundation construction, processes the existing site operation of on-the-spot rubble loaded down with trivial details, and the construction period is long.
The technical solution that realizes the utility model object is: a kind of concrete tapered pile basis, formed by several concrete tapered piles, concrete tapered pile comprises pile body and shoe, shoe two ends area is not etc., one end top little at area is provided with steel plate, steel plate wraps up top completely, one end and pile body that area is large connect as one, at pile body outer wall, U-shaped reinforcing bar is evenly set, along cross section, 2-4 group is evenly set, U-shaped Bar Anchorage end is fixed in pile body, notch is towards pile body, longitudinally every 0.5m-0.8m, one group of U-shaped reinforcing bar is set, and U-shaped reinforcing bar is apart from pile body top 0.3m, by stirrup by the U-shaped reinforcing bar binding of adjacent concrete tapered pile, adjacent concrete tapered pile is linked together, form concrete tapered pile basis.
Above-mentioned concrete tapered pile cross section is square or circular.
Every group of above-mentioned U-shaped reinforcing bar is no less than 1.
The utility model compared with prior art, its remarkable advantage: between (1) each centrum stake, be connected to each other, form Unified Global can effectively resist local sedimentation; (2) shoe part is halfpace type, effectively prevents inclination and the sinking of pile body; (3) reduce on-the-spot ground treatment construction order, construction is simple; (4) stick steel disc in shoe bottom, shoe bottom is destroyed when preventing that pile body from pressing down.
