Description
Technical field
This utility model relates to a kind of ground, particularly to a kind of composite foundation.
Background technology
Composite foundation refers to that subsoil part soil body during basement process is strengthened, or replaced, or in sky
So arranging reinforcement material in ground, stabilization zone is by matrix (the subsoil soil body or the modified subsoil soil body) and to strengthen
Body artificial foundation dimerous.Under load action, matrix and the effect of reinforcement shared load.According to compound
Composite foundation is divided into vertical reinforcement composite foundation and level to strengthening composite foundation two class by base load transfer mechanism, again perpendicular
It is divided into discrete material pile composite foundation, flexible pile composite foundation and rigid pile composite foundation three kinds to reinforcement composite foundation.
There are two problems in existing composite foundation: 1. the bearing capacity between can not get effectively utilizing；2. for tradition
Uplift pile for, uplift pile is served only for undertaking the buoyancy upwards that subsoil water produces, and does not share what superstructure was transmitted
Load downwards, the strength performance causing uplift pile high-strength can not give full play to.
Utility model content
This utility model provides a kind of composite foundation, and this composite foundation can be while improving the anti-pressure ability of uplift pile
Undertake load vertically downwards, and can effectively utilize bearing capacity between stake, there is simple in construction, feature with low cost.
In order to solve above-mentioned technical problem, this utility model provides following technical scheme:
This utility model one composite foundation, including resistance to plucking plate, several uplift piles that described resistance to plucking plate connects, described anti-
The lower section pulling out plate is provided with bed course；The top of described resistance to plucking plate, is disposed with mattress layer, blinding layer, steel wire from bottom to up
Layer and concrete layer；Described uplift pile includes pile body and is arranged on the concrete duct within pile body, outside described concrete duct
Wall connects several vertical reinforcements, is provided with the stirrup for the vertical reinforcement of colligation outside described vertical reinforcement.
As a kind of optimal technical scheme of the present utility model, the thickness of described bed course is 12-22cm；Described bed course is broken
Rock layers.
As a kind of optimal technical scheme of the present utility model, described pile body is rectangular structure.
As a kind of optimal technical scheme of the present utility model, described mattress layer thickness is 10-15cm；Described mattress layer is
Sand stone layer, maximum particle diameter is less than 20mm.
As a kind of optimal technical scheme of the present utility model, described uplift pile spaced set, it is anchored on resistance to plucking plate.
As a kind of optimal technical scheme of the present utility model, described pipe of concrete pipeline outer wall is connected with four and vertically adds
Strong muscle.
As a kind of optimal technical scheme of the present utility model, outside described vertical reinforcement, it is provided with several stirrups.
This utility model is reached to provide the benefit that: this utility model composite foundation can be in the resistance to compression improving uplift pile
Undertake load vertically downwards while ability, and can effectively utilize bearing capacity between stake, there is simple in construction, spy with low cost
Point；This utility model makes full use of the vertical high-strength bearing capacity of uplift pile, is collectively forming composite foundation with inter-pile soil, improves sky
So foundation bearing capacity and non-deformability, is beneficial to control deformation and the sedimentation on basis, while solving resistance to plucking problem, improves
The vertical bearing capacity of uplift pile.
