Description
Technical Field
The utility model belongs to the building structure field particularly, relates to a foundation ditch length secant pile is strutted.
Background
In present foundation pit engineering, the construction land is more and more nervous, and the surrounding environment is more and more complicated, because of the place restriction, many adopt vertical supporting construction, and its pile bolck produces great displacement easily, leads to the foundation pit initiative district soil body to take place great deformation, can adopt many piles body collocation use to long slope, and to short initiative district slope body, go out the anchor yet and do not have effectual scheme of blockking yet at present, and anchor area is too big, delays the construction site progress easily.
SUMMERY OF THE UTILITY MODEL
For solving the utility model discloses do not have the problem of effectual protection temporarily to short slope body among the current protective engineering, and provide a foundation ditch length secant pile and strut.
Provides a foundation pit long and short secant pile support, which comprises
The reinforced piles are vertically arranged;
the concrete pile is formed on one side of the reinforced pile and extends in parallel with the reinforced pile, and the concrete pile is wrapped on one side of the reinforced steel bar in a crescent shape and is integrally formed with the reinforced pile;
and a foundation pit is formed in one side, away from the reinforced pile, of the concrete pile, and concrete is filled and cured in the foundation pit.
Furthermore, the reinforced pile be a plurality of, every reinforced pile one side all corresponds there is the concrete pile, a plurality of reinforced piles become equidistant linear arrangement.
Furthermore, the length of the reinforced pile is greater than that of the concrete pile.
Furthermore, the corner of being connected of concrete pile and foundation ditch be provided with right angle bar, the both ends of angle bar pass through the bolt respectively with concrete pile and foundation ditch in concrete looks fixed connection.
Furthermore, the foundation pit is internally provided with a steel upright column close to the concrete pile, the steel upright column is positioned below the right-angle iron, and the steel upright column is fixedly connected with the bottom surface of the right-angle iron.
Further, the middle part that is located the steel stand is equipped with pre-buried connecting piece, pre-buried connecting piece's middle part and steel stand fixed connection, and one section of pre-buried connecting piece stretches into to the concrete pile in, and the other end of concrete pile stretches into to the interior concrete of foundation ditch, and the both ends of pre-buried connecting piece all have from top to bottom become the angle board that the right angle form stretches out.
Compared with the prior art, the utility model has the advantages that:
1. the method can reduce the displacement of the pile top under the condition of the same excavation depth, greatly reduces the ground deformation behind the pile, has better integrity by adopting the secant pile, increases the pile section area of the middle lower part of the row pile subjected to larger soil pressure, and improves the rigidity and the bearing capacity of the pile body.
2. The anchor cable supporting structure is suitable for foundation pit engineering which is supported by using a pile anchor supporting structure or an inner supporting structure or a single-row large-aperture pile supporting structure and a large-aperture single-row pile supporting structure, and compared with a pile anchor supporting method, the anchor cable supporting structure can shorten the length of an anchor cable, and even does not need the anchor cable supporting, thereby avoiding encroaching on an infrared underground space;
3. to interior supporting type supporting, the utility model discloses can reduce the occupation to the hole inner space, increase the convenience of construction. To traditional double row pile, the utility model discloses a length is shorter and for plain concrete's front row secant pile, and the cost is lower, and the cooperation is stabilized the soil body by the passive district soil body reinforcement means, and engineering cost is cheap.
4. To large aperture single row pile, the utility model discloses a single pore-forming diameter is littleer, and the construction degree of difficulty and risk are lower, compare with ordinary single row friction pile, have bigger lateral rigidity, can resist bigger soil pressure, keep the foundation ditch stable.
