Abstract
The utility model discloses a retaining reinforced structure of a deep foundation pit curb wall, which comprises filling piles and a retaining reinforced body. The utility model is characterized in that the filling piles are evenly arranged on the periphery of a foundation pit, the retaining reinforced body is arranged on the position that two filling piles are downward and the distance above the plane of the pit bottom is increased, and the retaining reinforced body is a plate body whose inner portion is provided with steel reinforcements and is poured with concrete. When in constructing, the phenomenon that the distance between the two filling piles are increased when the foundation pit is dug to the pit bottom occurs, the retaining reinforced body is arranged on the increased distance between the two filling piles, and the steel reinforcements in the reinforced body and main ribs in the filling piles are welded to prevent soil which pours into the foundation bit because of increased distance between the two filling piles. The utility model has the advantages of simple structure, convenient construction and excellent retaining effect.
Description
Technical field
The utility model relates to the deep foundation pit of soft soil foundation excavation and the stabilization works of technical field of buildings, and especially a kind of Extra-Deep Foundation Pit wall keeps off native ruggedized construction.
Background technology
The excavation of deep foundation ditch is a very complicated engineering that has risk, and it relates to the problem of mechanical strength, distortion and the stability of soil layer, relates to the INTERACTION PROBLEMS of soil layer and supporting and protection structure again, is a comprehensive stronger geotechnical engineering problem.High speed development along with urban construction, superelevation, continuing to bring out of building, requirement to building foundation pit is also more and more higher, along with large tracts of land, the continuous appearance of ultra-deep foundation pit, the degree of depth of bored pile is constantly deepened, the difficulty of the verticality of keyhole castinplace pile continues to increase, in the practice of construction process, the verticality of bored pile, the hole of collapsing, factors such as caliber cause the retaining wall part to have not closed state, because construction equipment, reason such as technology and soil property, the inclination of bored pile is difficult to avoid, when the boring run-off the straight, cause two gaps between the bored pile to strengthen, behind excavation of foundation pit along with the degree of depth, the outer water and soil of foundation ditch is easy to pour in foundation ditch inside by the gap between the castinplace pile, causes serious engineering accident; The method that adopts is to carry out slip casting or high-pressure rotary-spray soil mass consolidation in the foundation ditch outside at present, for deep foundation ditch, in the process of outside soil mass consolidation, aggravation impels the outside soil body to pour in the inboard on the contrary, not only effect is got half the result with twice the effort, but also causes engineering accident easily.
Summary of the invention
The purpose of this utility model is a kind of Extra-Deep Foundation Pit wall soil-baffling structure that provides at the deficiencies in the prior art, and it is simple in structure, easy construction, and retaining soil is effective.
The concrete technical scheme that realizes the utility model purpose is:
A kind of Extra-Deep Foundation Pit wall soil-baffling structure, comprise that castinplace pile, retaining soil add solid, characteristics are castinplace piles with the uniform setting of foundation ditch periphery, and retaining soil adds solid and is arranged on two castinplace piles and spacing increase place on the baseplane, hole downwards, and retaining soil adds the plate body that solid is established reinforcing bar and fluid concrete in being; Main muscle welding in reinforcing bar in it and the castinplace pile.
The utility model is simple in structure, easy construction, and retaining soil is effective.
Description of drawings
Fig. 1 is the utility model structural representation
Fig. 2 is provided with floor map for castinplace pile
The specific embodiment
Consult Fig. 1, the utility model comprises that castinplace pile 1, retaining soil add solid 2, castinplace pile 1 is with the uniform setting of foundation ditch periphery, and retaining soil adds solid 2 and is arranged on two castinplace piles 1 and spacing increase place on the baseplane 6, hole downwards, and retaining soil adds the plate body that solid 2 is established reinforcing bar 4 and fluid concrete 5 in being; Reinforcing bar 4 in it and 3 welding of the main muscle in the castinplace pile 1.
Consult Fig. 1, Fig. 2, during construction, the uniform castinplace pile 1 that is provided with of foundation ditch 7 peripheries, because the existence of castinplace pile 1 perpendicularity deviation, have two castinplace piles, 1 spacing during the end to the hole and increase phenomenon when digging behind the excavation, this moment retaining soil is set in the spacing of two castinplace piles, 1 increase and adds solid 2,, just can stop the earth that pours in foundation ditch because of the increase of two castinplace piles, 1 spacing 3 welding of the main muscle in reinforcing bar in it 4 and the castinplace pile 1.
