Abstract
The utility model relates to a civil engineering structure, and in particular relates to a middle pit structure of a soft-soil deep foundation pit. A plurality of mixing piles are longitudinally arranged in the containment of the foundation pit and stick to the outer wall of the foundation pit. The middle pit structure has the characteristics that the design is reasonable, the construction cost is low, the stability is good and the deformation is not liable to occur.
Description
Technical field
The utility model relates to a kind of civil engineering structure, especially relates in a kind of Soft Soil Foundation Pit cheating structure.
Background technology
Generally, building needed to dig to put in the corresponding deep foundation ditch before build on ground and cheats.Present most of building all has basement, considers that the hole is nearer apart from Basement pit supporting in the deep foundation ditch, and is larger on the impact of pattern foundation pit supporting structure stabilization and deformation, adds the restriction in some place, brings certain difficulty to hole construction in the deep foundation ditch.Although existingly put stable that sloping method of support strengthened cheating in the deep foundation ditch, bring certain impact also for simultaneously the stabilization and deformation of bracing of foundation pit, and the backfill amount be larger, has caused the complexity of construction technology, has increased the cost of constructing.
Summary of the invention
The utility model mainly is that construction cost is higher, less stable for the existing complex structure of prior art, easily cause the technical problem of distortion etc., provide a kind of simple in structure, construction cost is lower, stability better is difficult for causing in the Soft Soil Foundation Pit of distortion and cheats structure.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: some agitation piles vertically are set in bracing of foundation pit, and agitation pile and foundation ditch outer wall are affixed.Agitation pile is as support system, and supporting intensity and rigidity are suitable, and is safe.
As preferably, acquire the brick loose tool in the foundation ditch, be filled with concrete protection between brick loose tool and the foundation ditch outer wall.
Therefore, the utlity model has design more reasonable, construction cost is lower, and stability better is difficult for causing the characteristics such as distortion.
Description of drawings
The specific embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: vertically insert two cement mixing piles 2 in bracing of foundation pit 1, dig out foundation ditch 3 according to the absolute altitude that sets in advance between cement mixing pile 2, cement mixing pile 2 is affixed with the outer wall of foundation ditch 3.Acquire brick loose tool 4 in the foundation ditch 3, be filled with concrete protection 5 (as shown in Figure 1) between brick loose tool 4 and foundation ditch 3 outer walls.
Claims (2)
1. cheat structure in a Soft Soil Foundation Pit, be made of bracing of foundation pit and the foundation ditch that is arranged on wherein, it is characterized in that vertically arranging some agitation piles (2) in described bracing of foundation pit (1), agitation pile (2) is affixed with foundation ditch (3) outer wall.
2. cheat structure in the Soft Soil Foundation Pit according to claim 1, it is characterized in that acquiring in the described foundation ditch (3) brick loose tool (4), be filled with concrete protection (5) between brick loose tool (4) and foundation ditch (3) outer wall.
