Abstract
The utility model discloses an arch steel sheet pile supporting structure, relates to an arch steel sheet pile foundation pit supporting structure, and belongs to the field of the geotechnical engineering. The arch steel sheet pile supporting structure comprises steel sheet piles and two groups of bored cast-in-place piles; the bored cast-in-place piles are respectively arranged in parallel on a foundation pit; and a plurality of steel sheet piles, which are connected to form an arch-shaped structure, are arranged at the upper ends of the bored cast-in-place piles. The utility model fulfills the aims that the stress is reasonable; the riser condition cannot occur; and the arch steel sheet pile supporting structure has strong adaptability, is convenient to construct and is more beneficial for preventing water penetration and soil leakage.
Description
Technical field
The utility model relates to a kind of arch steel sheet piling pit supporting construction, and affiliated field is a geotechnical engineering.
Background technology
Excavation of foundation pit and supporting are complicated system engineering, relate to engineering geology, hydrogeology, engineering mechanics, engineering structures, soil mechanics and Foundation Design and engineering construction and management etc., are to melt the comprehensive branch of learning of multi-door subject knowledge in one.Along with the progress of above each subject, enclosing Technique for Deep Foundation Pit has also obtained very big development, mainly shows three aspects: the one, and improve and improve the space enclosing structure design calculation theory, design is more tallied with the actual situation; The 2nd, reinforce the inside and outside soil body in hole, improve the self-reliance of the inside and outside soil body in hole; The 3rd, seek more reasonably space enclosing structure form, improve the force-bearing situation of space enclosing structure, improve it and go along with sb. to guard him ability.
Existing pattern foundation pit supporting structure form mainly contains: cantilever supporting, interior support (or drawing anchor) supporting, contraryly do arch wall supporting, combined supporting etc.The arching structure is just to begin a kind of Extra-Deep Foundation Pit form of structure of using in recent years.The general linear pattern space enclosing structure of the distortion of this space enclosing structure is little, and buttress mainly receives a power (pressure) effect, and fractional load passes to arch springing through level arch, cancel out each other about the load major part of arch springing and pass to, and reasonable stress, cost is low.Present this space enclosing structure mainly contains two kinds of forms, and a kind of is that buttress is arranged in arch by cement mixing method and forms, and the arch springing place establishes 1～2 bored pile, supports to be located in the arch springing stake; Another kind is that buttress is arranged in arch by mini-pile and forms, and the arch springing stake is a large diameter bored pile, can establish on the arch springing to support or as cantilever construction.First kind of form of structure is because the buttress cement mixing method overlaps mutually, so globality is better and good sealing performance is arranged, but because soil cement intensity is low, so buttress is thicker, but still the wall thickness of force of gravity formula EFFECT OF CEMENT STABILIZED SOIL RETAINING WALL wants much little.Second kind of form of structure is not because the buttress castinplace pile overlaps, and globality is relatively poor and the sealing function is relatively poor, but the buttress strength of materials is high.
Summary of the invention
The utility model purpose provides reasonable stress, the situation of skirt can not occur, and compliance is strong, and easy construction more helps percolation-proof, the native arch steel sheet pile supporting and protection structure of leakproof.
The utility model adopts following technical scheme for realizing above-mentioned purpose:
A kind of arch steel sheet pile supporting and protection structure comprises steel sheet pile, two groups of bored piles, the bored pile that laterally arranges respectively on the foundation ditch, and the upper end of bored pile is provided with several steel sheet piles that is interconnected to form arch.
Every group of bored pile of the utility model is 1～2.
The utility model adopts technique scheme; Compared with prior art has following advantage: the utility model reasonable stress; It is the stronger space enclosing structure of a kind of self-reliance; Even under the insertion depth situation relatively poor than pitting subsoil matter, as long as can guarantee space enclosing structure whole unstability and bulge fracture do not take place, the situation of skirt generally can not appear.It is strong to have compliance, and easy construction more helps advantages such as percolation-proof, leakproof soil, and is more reasonable more economically than other foundation pit supporting construction form.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model.
The specific embodiment
Be elaborated below in conjunction with the technical scheme of accompanying drawing to the utility model:
As shown in Figure 1, a kind of arch steel sheet pile supporting and protection structure comprises steel sheet pile 1, two groups of bored piles 2, the bored pile 2 that laterally arranges respectively on the foundation ditch, and the upper end of bored pile 2 is provided with several steel sheet piles that is interconnected to form arch 1.
Every group of group bored pile of the utility model 2 is 1～2.
The utility model the time may further comprise the steps in construction: (1) according to site condition and computational analysis, confirm the stake of steel sheet pile long with model, confirm the excavation progression of foundation ditch; (2) the slotting steel sheet pile of beating forms domes; (3) construction drill castinplace pile; (4) excavation pit; (5) the foundation ditch hole is cleared up, is flattened and carry out next step construction working the end.
Claims (2)
1. arch steel sheet pile supporting and protection structure; It is characterized in that comprising steel sheet pile (1), two groups of bored piles (2); The bored pile (2) that laterally arranges respectively on the foundation ditch, the upper end of bored pile (2) is provided with several steel sheet piles that is interconnected to form arch (1).
2. arch steel sheet pile supporting and protection structure according to claim 1 is characterized in that every group of bored pile (2) is 1～2.
