Description
Technical field
The utility model relates to technical field of building construction, is particularly a kind ofly applicable to the Pile Foundation reverse construction vertical supporting system integrated with diaphragm wall.
Background technology
Along with developing rapidly of China's building trade, highrise building, even super highrise building adopt the object of construction production of reverse construction to increase gradually.In reverse construction process, the load of underground beam slab and the vertical load of superstructure need vertical supporting System Take and are passed to basis, so the design and construction of vertical supporting system becomes the inverse important and difficult issues done in the design and construction stage of whole engineering in contrary working method engineering.The form of " one pile for one column " or " many, a post " that the general vertical supporting system of bearing structural beam slab load and construction load adopts structural column to combine with engineering pile usually.According to practical engineering experience, " one pile for one column " vertical supporting system that conventional angle splice joint lattice column and stand column pile form only can bear 2 ~ 3 layers of superstructure load.And the steel post that bearing capacity is higher " one pile for one column " bears 6 ~ 8 layers of superstructure load only.And the speed of application of superstructure is wanted far faster than the speed of underground structure adverse construction method, but due to conventional vertical supporting system bearing power restriction, superstructure is usually constructed to need to suspend to underground structure after the restriction number of plies and is completed, and vertical supporting system just can continue the construction of superstructure after can providing enough supporting capacity.Therefore, the routine " one pile for one column " that reverse construction adopts usually or " many, a post " vertical supporting system bearing power deficiency become the key affecting superstructure speed of application, this to a certain degree can delay Engineering Overall progress, reduces the advantage that the upper and lower synchronous construction of highrise building contrary sequence method shortens construction period.In addition, the vertical supporting system of " one pile for one column " or " many, a post " of prior art, due to its comparatively scattering device, when stress point is positioned at the corresponding position of stake, a sedimentation can be produced, and be uneven sedimentation, therefore had a strong impact on the supporting capacity of vertical supporting system and overall rigidity, the vertical supporting system particularly below Core Walls Structure position is more obvious.
Utility model content
Technical problem to be solved in the utility model is, the reverse construction vertical supporting system providing a kind of pile foundation integrated with diaphragm wall, to improve vertical bearing capacity and overall rigidity requirement, and the bulk settling of vertical supporting system and uneven sedimentation can be reduced.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: the reverse construction vertical supporting system that a kind of pile foundation is integrated with diaphragm wall, comprise the diaphragm wall of reinforced concrete structure, and along the bottom of described diaphragm wall the pile foundation of reinforced concrete structure extended downwards, the integrated pouring construction of described diaphragm wall and described basis.
Further, the reverse construction vertical supporting system that the pile foundation that the utility model provides is integrated with diaphragm wall, described diaphragm wall, comprise the continuous wall trench underground being positioned at below ground location corresponding to core tube of high-rise building and arranging, be provided with diaphragm wall reinforcing cage in described continuous wall trench underground, described continuous wall trench underground and underground connection wall reinforcing cage have built concrete.
Further, the reverse construction vertical supporting system that the pile foundation that the utility model provides is integrated with diaphragm wall, described pile foundation, comprise and be positioned at described continuous wall trench underground several pile foundation pore-formings connected with described continuous wall trench underground are evenly set with downward-extension, be provided with pile foundation reinforcement cage in each described pile foundation pore-forming, described pile foundation pore-forming and pile foundation reinforcement cage have built concrete; Described continuous wall trench underground, diaphragm wall reinforcing cage and described pile foundation pore-forming, pile foundation reinforcement cage primary concreting concrete form diaphragm wall and the pile foundation of the integration of reinforced concrete structure.
Further, described pile foundation reinforcement cage is provided with reserved section reinforcing bar, and described reserved section reinforcing bar inserts in described diaphragm wall reinforcing cage.
Further, the reverse construction vertical supporting system that the pile foundation that the utility model provides is integrated with diaphragm wall, the periphery of described diaphragm wall is provided with auxiliary pile basis.
Further, the reverse construction vertical supporting system that the pile foundation that the utility model provides is integrated with diaphragm wall, described auxiliary pile basis, comprises engineering pile and structural column.
Further, the reverse construction vertical supporting system that the pile foundation that the utility model provides is integrated with diaphragm wall, described structural column is the lattice column of steel post or angle splice joint.
Compared with prior art, the reverse construction vertical supporting system that the utility model pile foundation is integrated with diaphragm wall, comprise the diaphragm wall of the reinforced concrete structure that integration is built, and the pile foundation of the reinforced concrete structure extended downwards along the bottom of described diaphragm wall.With the vertical supporting system of employing pile foundation structure pure in alternative prior art.That is, the upper/lower positions accordingly of the Core Walls Structure of highrise building adopts the integration diaphragm wall of building and pile foundation to constitute integrated reverse construction vertical supporting system by the utility model.Because diaphragm wall is reinforced concrete structure, its vertical bearing stress and integral rigidity are far longer than bearing stress and the rigidity of the vertical supporting system adopting separately pile foundation, in addition, the pile foundation extended bottom diaphragm wall has consolidated and strengthened again stability and the reliability of diaphragm wall, and namely pile foundation further improves bearing stress and the rigidity of diaphragm wall.In addition, reverse construction vertical supporting system of the present utility model, owing to have employed the diaphragm wall of reinforced concrete structure as support, compared with the vertical supporting system of " one pile for one column " in prior art or " many, a post ", the support system of its corresponding Core Walls Structure position is comparatively concentrated, therefore, it is possible to reduce the bulk settling of this support system and uneven sedimentation.In addition, after the reverse construction vertical supporting system adopting pile foundation of the present utility model integrated with diaphragm wall, in reverse construction process, without the need to waiting for that Underground Construction completes the construction that just can proceed superstructure, thus accelerate the construction speed of the superstructure of highrise building, there is raising efficiency of construction, shorten the effect of construction period.
