Work cost.Currently, design installation compound bucket foundation by concrete changeover portion, steel cylinder and divide storehouse board group at.In order into one
Step reduces the cost of bucket foundation, under the premise of guaranteeing design strength requirement, can substitute steel cylinder with concrete cylinder.
Barrel thickens the resistance that will definitely increase in sinking watching, generallys use blade foot ultra-wide means at present and reduces coagulation
The penetration resistance of soil cylinder needs to design to probe into influence of the width of ultra-wide for entire concrete cylinder penetration resistance
The blade foot ultra-wide of different in width helps sink device to compare experiment.Due to concrete to pour curing cycle longer, greatly increase
The experimental period of simulated experiment.Therefore, experimental cost can be reduced by being now badly in need of one kind, shorten experimental period, being capable of rapid and convenient
Simulation blade foot difference ultra-wide width, on concrete cylinder penetration resistance influence experimental provision.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art described above, it is desirable to provide and one kind can reduce experimental cost,
Shorten experimental period, can quickly and easily simulate blade foot difference ultra-wide width, the reality that concrete cylinder penetration resistance is influenced
Experiment device.
In order to achieve the above objectives, the technical scheme of the present invention is realized as follows:
A kind of experimental provision that simulation blade foot ultra-wide influences heavy wall concrete penetration resistance, including blade foot, the blade foot
Top central portion is fixedly installed concrete column, and the top surface of the blade foot is provided with lower part in concrete column two sides at equal intervals
Fixture block, the concrete column top side are fixedly installed top plate；The bottom surface of the top plate is provided with upper with the cooperation of lower part fixture block
Portion's fixture block, the top surface of the top plate correspond to concrete column and are provided with displacement meter, pressure meter and inclinator；The concrete is vertical
Between the top fixture block and lower part fixture block of column two sides, it is inserted with the concrete slab being attached on concrete column, is located at outermost
Concrete slab on be provided with earth pressure gauge and pore pressure gauge.
Further, the concrete column, top plate and blade foot are integral each other by built-in fitting fixation.
Further, the distance between described lower part fixture block and the distance between the top fixture block are 2cm-
4cm。
Further, the concrete slab with a thickness of 2cm-4cm.
Further, the earth pressure gauge and the pore pressure gauge are embedded in outermost concrete side by side at equal intervals
The outer end of plate, earth pressure gauge and pore pressure gauge are 26.
Further, the section of the blade foot is triangle.
Compared with the existing technology, the invention has the following advantages:
The present invention is in the experiment of concrete cylinder penetration resistance, by concrete column simulation concrete cylinder, compared to pouring
The concrete cylinder mould type for building different blade foot ultra-wide width, is greatly saved experimental material.Concrete column portion in experimentation
It is point constant, by adding the identical concrete slab of quantity in concrete column two sides, the thickness of concrete column is changed,
To change the width that blade foot two sides exceed concrete column.By changing the concrete slab of different number, different blade foots are realized
The experimental variable of ultra-wide width controls, and is conducive to the Variable Control of comparative experiments, the experimental model assembling transformation letter of different operating conditions
It is single, substantially reduce the experimental period of entire exploring experiments.

Specific embodiment
The present invention will be described in detail below with reference to the accompanying drawings and embodiments.
As shown in Figure 1 to Figure 3, a kind of experimental provision that simulation blade foot ultra-wide influences heavy wall concrete penetration resistance, packet
Blade foot 5 is included, 5 top central portion of blade foot is fixedly installed concrete column 3, and the top surface of the blade foot 5 is at 3 liang of concrete column
Side is provided with lower part fixture block 4 at equal intervals, and 3 top side of concrete column is fixedly installed top plate 1；The bottom surface of the top plate 1
It is provided with the top fixture block 2 cooperated with lower part fixture block 4, the top surface of the top plate 1 corresponds to concrete column 3 and is provided with displacement meter
11, pressure meter 9 and inclinator 10；Between the top fixture block 2 and lower part fixture block 4 of 3 two sides of concrete column, it is inserted with
The concrete slab 6 being attached on concrete column 3 is provided with earth pressure gauge 7 and pore water pressure on concrete slab 6 on the outermost side
Power meter 8, the earth pressure gauge 7 and the pore pressure gauge 8 are embedded in the outer of outermost concrete slab 6 side by side at equal intervals
End, earth pressure gauge 7 and pore pressure gauge 8 are 2-6；The concrete column 3, top plate 1 and blade foot 5 are each other by pre-buried
Part fixation is integral；The distance between described lower part fixture block 4 and the distance between the top fixture block 2 are 2cm-4cm,
The concrete slab 6 with a thickness of 2cm-4cm；The section of the blade foot 5 is triangle.
Concrete column 3, top plate 1 and blade foot 5 in the present invention is integral each other by built-in fitting fixation, and end face is neat
It is flat, convenient for plugging concrete slab and measurement experiment data.Top fixture block 2 and lower part fixture block 4 are corresponding, are fixed using welding manner
On top plate 1 and blade foot 5.Before starting experiment, first needed according to blade foot 5 relative to concrete column 3 to be simulated beyond width, In
The concrete slab 6 of different number is added between top fixture block 2 and lower part fixture block 4.The side wall that concrete slab 6 is close to column two sides is opened
Begin to be inserted into, the concrete slab 6 of identical quantity is then sequentially inserted into column two sides, and ipsilateral concrete slab 6 is mutually close to.It is mixed
The distance between thickness and fixture block of concrete board 6 are 2cm, while keeping fixture block and concrete slab mating, are reduced as far as possible
The different-thickness of column is preferably simulated in gap between concrete slab.When top plate 1, concrete column 3, blade foot 5 and concrete
For plate 6 when the length in concrete slab direction of insertion is consistent, the data that this experimental provision measures are most stable, and effect is best.It installs additional
After complete concrete slab 6, it can record in real time and be somebody's turn to do by the pressure meter 9, inclinator 10 and displacement meter 11 installed on 1 top of top plate
Penetration resistance, inclination angle and the displacement data of experimental model sinking watching realize that quickly and easily the different ultra-wide of simulation blade foot 5 are wide
Degree, the experiment condition that concrete cylinder penetration resistance is influenced.
After experiment, each concrete slab 6 can be dismantled from 3 two sides of concrete column.Then exceeded according to 5 two sides of blade foot
The change width of concrete column 3 adds the concrete slab 6 of identical quantity in column two sides again, carries out repeating experiment, comparison
The drag data measured.In the concrete slab 6 that 3 two sides outermost end of concrete column plugs, fixed use sets in experiment for the first time
Two concrete slabs 6 of earth pressure gauge 7 and pore pressure gauge 8 are equipped with, consequently facilitating the frictional resistance of column two sides carries out
Measurement.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
