Abstract
The present invention is a kind of scalable header tank in diaphram wall end, it is welded using steel plate, the flexible of length is realized using the stroke of hydraulic cylinder, oil cylinder backhaul conveniently enters slot, cylinder ejector pushes against steel reinforcement cage and cell wall, after concrete initial set, oil cylinder backhaul conveniently goes out slot, is connected using multiple single-units and is reached using depth.
Description
Technical field:
The present invention relates to the realm of building construction, the packing for foundation pit construction diaphram wall header space.
Technical background:
Currently, in the processing method of diaphram wall header space, under being mainly for the steel reinforcement cage that there is fashioned iron in end
Section throws and fills out sand hill, upper section header tank, then the method with the compacted header tank of sand hill.It is time-consuming, handle bad, concrete generation
Even header tank is streamed all not mention not come out.
The method of the cylindrical shape that also useful rubber is made into, interior inflatable body or liquid pressing expansion packing end.Due to mixed
Pressure during pouring on solidifying is very big, and fashioned iron can deform, and rubber product is flexible material, and rigid branch can not be formed to fashioned iron
Support.
There is no the steel reinforcement cage of fashioned iron for end, do not have to sand hill, header tank is wrapped up by concrete, and decentralization depth is more shallow, is applied
Work difficulty is bigger.
Summary of the invention:
The present invention is a kind of scalable header tank in diaphram wall end.It is welded using steel plate, utilizes hydraulic cylinder
Stroke realizes the flexible of length, and multiple single-units are connected up to working depth.
Length shortens after hydraulic cylinder backhaul, facilitates and is put into slot under header tank, enters hydraulic cylinder pressurization ejection after slot, makes to seal
Head case both ends are respectively held against steel reinforcement cage and cell wall, are to rely on cell wall using hydraulic oil in the incompressible principle of confined space
The support of a rigidity is formed to steel reinforcement cage.The hydraulic cylinder backhaul after concrete casting initial set, conveniently lifts out slot.
The utility model has the advantages that
For the present invention compared to original technology, it can be achieved that full depth packing to steel reinforcement cage header space, it is convenient to enter and leave slot,
Rigid support is formed to steel reinforcement cage, is deformed steel reinforcement cage not during concrete pours.For end without fashioned iron
Steel reinforcement cage, header tank can be made into respective shapes by design requirement in the corresponding surface of steel reinforcement cage.
Detailed description of the invention:
Fig. 1 is front elevation
Fig. 2 is length oil cylinder installation diagram
Fig. 3 is width oil cylinder installation diagram
1 box supporting surface, 2 box supporting surface, 3 length oil cylinder, 4 width oil cylinder in figure
Specific implementation method:
After steel plate cutting, it is welded into the box-shaped support face of (1) (2) two one side openings.Supporting surface (2) wants that support can be buckled into
In face (1).The both ends of oil cylinder (3) are individually fixed on (1) (2) supporting surface, and the flexible of oil cylinder (3) can drive supporting surface
It stretches
Contracting, oil cylinder (4) are fixed in the width direction of supporting surface (2), are realized to the support on width.All oil cylinders (3)
(4) linked with pipeline.There are connectors for two ends in box-shaped support face (1) (2), for being connected with each other.
For, 60 meters deep, 6.8 meters of flute length 1.2 meters thick by diaphram wall, steel reinforcement cage are 6 meters, 0.8 meter of header space long.This
1.15 meters of width of invention design, backhaul is 0.6 meter long, and ejection is 1.0 meters long.Using 4 15 centimetres of diameter, 40 centimetres of stroke, design
The oil cylinder of 31.5 megapascal of pressure, total stress under design pressure are 220 tons.Use the cross of 3 10 centimetres of diameter, 5 centimetres of strokes
To support cylinder, 6 meters of height unijunction.10 unijunctions connection when work, when oil cylinder backhaul, conveniently enter slot, enter the pressurization of slot rear pump or output pump,
Steel reinforcement cage and cell wall are pushed against after cylinder ejector, and concrete can be poured after pressure maintaining.After concrete initial set, oil cylinder backhaul is convenient
Lift out slot.
The above description is only a preferred embodiment of the present invention, therefore all according to construction described in the present patent application range, feature
And the equivalent change or modification that principle is done, it is included in the scope of the present invention.
Claims (2)
1. the scalable header tank in a kind of diaphram wall end, it is characterized in that: every 1 single-unit is welded into two one sides by steel plate
