Abstract
The utility model discloses a retaining wall foundation structure which is composed of a supporting pile foundation embedded under the ground and a joist directly supporting a retaining wall. The retaining wall foundation structure adopted at the wall bottom of the retaining wall enables the force system at the wall bottom of the retaining wall to be transferred to the subsoil through the retaining wall foundation structure, improves the bearing capacity of the subsoil of the retaining wall, simultaneously reduces the excavation face of the subsoil, and enlarges the use range of the retaining wall while ensuring the retaining wall foundation to be safe and stable. The whole retaining wall foundation structure can be taken as a plane frame structure embedded into the subsoil, and has the advantages of simple structure, flexible and convenient construction, easily controlled construction quality, good long-term reinforcing effect, and the like.
Description
Technical field
The utility model relates to the retaining wall technical field, relates in particular to a kind of retaining wall foundation structure.
Background technology
Retaining wall is the primary structure pattern of slope reinforcement in the civil engineering, and its bearing capacity of foundation soil is the high key factor of control retaining walls.The present general open cut foundation that adopts in the basis of retaining wall, when needing to improve the retaining wall bearing capacity of foundation soil, the main employing enlarges the basis, changes and fill out or add mode such as deep foundation.Darker when open cut foundation, or retaining wall is positioned at abrupt slope, thin bar embankment location, and when improving the retaining wall bearing capacity of foundation soil by the way or satisfying its embedding requirement, open cut foundation just is difficult to guarantee construction and personal safety, even causes big engineering project disaster.
Summary of the invention
The purpose of this utility model is to overcome above shortcomings in the prior art, provides a kind of and can improve bearing capacity of foundation soil, reduces the retaining wall foundation structure of foundation excavation.
To achieve these goals, the technical scheme that the utility model adopted is: a kind of retaining wall foundation structure, constitute by pile foundation 3,4 and joist 2, and described pile foundation 3,4 build-ins are under the face of land 1; The top of pile foundation 3,4 connects by joist 2.
Described pile foundation 3,4 is the braced structures of retaining wall foundation structure, and joist 2 is for directly bearing the structure of power system at the bottom of the retaining walls, and pile foundation 3,4 and joist 2 are reinforced concrete structure, and pile foundation 3,4 and joist 2 hold together by reinforcing bar.
When the utility model was used in engineering, under the face of land, the top of pile foundation 3,4 connected by joist 2 with passive pile foundation 3,4 build-ins, and joist 2 is built retaining wall 5 with after pile foundation 3,4 is connected on the top of joist 2.
Compared with prior art, the beneficial effects of the utility model are: the utility model adopts at the bottom of retaining walls by supporting the retaining wall foundation structure that pile foundation and joist are formed, power system has passed in the ground by retaining wall foundation structure at the bottom of making retaining walls, can improve the retaining wall bearing capacity of foundation soil, can reduce simultaneously the excavation face on basis, when guaranteeing that retaining wall is basic safely, stable, enlarged the scope of application of retaining wall.Whole retaining wall foundation structure of the present utility model can be considered as imbedding the plane rigid frame structure in the ground, has simple in structure, construction flexible and convenient, construction quality and is easy to characteristics such as control, long-term consolidation effect are good.

Reference numeral wherein: 1-face of land, 2-joist, 3,4-pile foundation, 5-retaining wall.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Preferred embodiment
As shown in the figure, the retaining wall foundation structure of present embodiment, the joist 2 of power system constitutes by passive pile foundation 3,4 and at the bottom of directly bearing retaining walls, pile foundation 3,4 is the braced structures of retaining wall foundation structure, joist 2 is for directly bearing the structure of power system at the bottom of the retaining walls, pile foundation 3,4 and joist 2 are reinforced concrete structure, hold together by reinforcing bar.
When the utility model was used in engineering, under the face of land 1, the top of pile foundation 3,4 connected by joist 2 with passive pile foundation 3,4 build-ins, and joist 2 is built retaining wall 5 with after pile foundation 3,4 is connected on the top of joist 2.
