Abstract
The utility model discloses a floating negative pressure basis integrated configuration comprises a plurality of steel drums, a plurality of baffle, apron and superstructure, its characterized in that: a plurality of drums join into a whole through a plurality of baffles, and the top sets up the apron and forms a plurality of compartments that have the lid not have the end, but the air vent of switch is established at every compartment top. Foundation structure mainly carries out the negative pressure through a plurality of steel drum compartments and sinks, mixes the compartment exhaust or is aided with less vacuum to control the load that the baffle receives at suitable within range as far as possible, the load reaches foundation structure through superstructure, and the superstructure pattern can be selected according to the atress characteristic. The utility model discloses structural weight is light, and construction convenience is swift, and convenient preparation installation, handling can be floated on silt matter sea bed. Require to hang down to the precast plant, the construction is fast, and the turnover is fast, can carry out fabricated construction. And do not destroy the original structure of the soil body.
Description
Technical field
This utility model floating negative-pressure foundation combinative structure, belongs to port engineering, coastal engineering and hydraulic engineering field.
Background technology
It is frequently encountered by soft soil foundation, for bearing greater level at present in port engineering, coastal engineering and hydraulic engineering
The building of power and vertical force need to process to improve its bearing capacity to ground, and traditional method is to use pile foundation or loading
Discharging consolidation processing mode, its not only speed of application slow, and basement process is costly, bears to this end, propose a kind of novel floating
Pressure basis combinative structure, this basis combinative structure is by transportation by driving after integral manufacturing to on-the-spot, and negative pressure sinks down in soft soil foundation, floating
On soft soil foundation, it is not necessary to enter good supporting course, not destroying the original state of the soil body, speed of application is fast, and cost is low, can extensively answer
For soft soil foundation.
The acquired barrel-shaped base structure of back-off thin-walled (patent name: the barrel-shaped base structure of back-off thin-walled, the patent No.: ZL
2011 2 0104097.2) clapboard stress is unreasonable, clapboard stress requirement is high and fragile in sinking, it is proposed that Duo Gewu
The combinative structure that end steel cylinder (with five as case) is combined with concrete cover, so that structure stress is more reasonable, constructs more square
The most efficient.
Summary of the invention
The purpose of this utility model is to provide a floating negative-pressure foundation combinative structure, solves to tie under Soft Soil
The vertical bearing capacity of structure and horizontal bearing capacity problem, and then reduce construction costs, reduction of erection time.
To achieve these goals, this utility model is realized by the following technical programs:
Floating negative-pressure foundation combinative structure is made up of multiple steel cylinders, multiple dividing plate, cover plate and superstructure, and its feature exists
In: multiple cylinders are coupled to an entirety by multiple dividing plates, and top arranges cover plate and forms multiple compartment having lid bottomless, each
Compartment top sets switchable passage.Base structure mainly carries out negative pressure sinking by multiple steel cylinder compartments, mixes compartment
Aerofluxus or be aided with less vacuum, to control dividing plate load in the range of suitably as far as possible；Load passes through superstructure
Reaching base structure, superstructure pattern can be selected according to stress characteristic.
As preferentially, the vertical load that described negative pressure is sunk is spread by cylinder, thus without weak soil in process cartridge.
Force principle of the present utility model is: in the range of upper vertical load is diffused to multiple steel cylinder, and then
Meet the requirement for bearing capacity of undisturbed soil.Ground is when bearing instantaneous short-term vertical load simultaneously, owing to compartment top passage is closed,
Storehouse internal drainage speed is relatively slow, and pore water pressure quickly increases to offset the vertical force increased suddenly.When bearing horizontal force, basis model
Enclosing interior soil and can be considered rigid body, before relying on the bigger frictional resistance and cylinder produced of conducting oneself with dignity, passive earth pressure bears horizontal force.
Beneficial effect: this utility model dead load is light, convenient and quick construction facilitates fabrication and installation, handling, can be floating
On muddy sea bed.Requiring low to precast plant, construction is fast, and turnover is fast, can carry out fabricated construction.By steel circle during work
Upper load is diffused in bigger scope by cylinder and cover plate, and this structure floats on soft soil foundation, it is not necessary to enter good supporting course,
Not destroying soil body original structure, structure has good integrity, reasonable stress, and manufacturing conditions is excellent, and sinking speed is fast, and cost is low
Advantage, it is adaptable to soft soil foundation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the profile of Fig. 1.
1. steel cylinder, 2. dividing plate, 3. cover plate, 4. superstructure in figure, the 5. passage on cover plate.
Detailed description of the invention
Floating negative-pressure foundation combinative structure as shown in Figure 1 and Figure 2, this structure is by five steel cylinders (1), six dividing plates
(2), cover plate (3) and superstructure (4) composition, the most just define five cylinder compartments and two mixing compartments, each compartment
The cover plate at top is respectively provided with switchable passage (5).Cover plate (3) and superstructure (4) use xoncrete structure.
After this utility model is made by land, by half latent transportation by lighter to job site, half dives refutes sinking, this structure air supporting
To erecting bed, opening the switchable passage on cover plate behind location, discharge gas in storehouse, structure starts under Gravitative Loads
Sink, the vacuum reaching certain of then drawing water in tower silo, structure cover plate continues to sink under inside and outside differential pressure effect, until
Sink to designed elevation.Superstructure can be prefabricated together with basis, it is possible to the most prefabricated, the later stage lays.
Claims (2)
1. floating negative-pressure foundation combinative structure is made up of multiple steel cylinders, multiple dividing plate, cover plate and superstructure, and its feature exists
In: multiple cylinders are coupled to an entirety by multiple dividing plates, and top arranges cover plate and forms multiple compartment having lid bottomless, each
Compartment top sets switchable passage；Base structure mainly carries out negative pressure sinking by multiple steel cylinder compartments, mixes compartment
Aerofluxus or be aided with vacuum degree control dividing plate load.
2. floating negative-pressure foundation combinative structure as claimed in claim 1, it is characterised in that: the vertical load that described negative pressure is sunk
Spread by cylinder, thus without weak soil in process cartridge.
