Abstract
The present invention provides a kind of device for plugging for steel suspended box cofferdam, including top panel, the top panel offers the upper port mutually agreed with the outer diameter of steel pile casting, the conical sleeve for the nested steel pile casting is vertically provided with around the upper port, the lower port of the conical sleeve is provided with the lower baffle plate of hollow structure.The present invention guides the bottom concrete poured to flow to lower baffle plate, the gap between steel pile casting and lower baffle plate is blocked by doughnut sandbag, good airproof performance, is not easy that concrete is made to outflow by setting conical sleeve.
Description
Technical field
The present invention is hung about the Construction Technology of Rider field in underwater science of bridge building, more particularly, to one kind for steel
The device for plugging of cofferdam.
Background technique
In bridge deepwater foundation steel suspension box-cofferdam when construction operation, steel lifted trunk needs before transferring after-pouring bottom concrete in place
Leak stopping is carried out to gap between steel lifted trunk bottom plate and steel pile casting.There are mainly two types of for method for blocking in the prior art: one
It is to be centered around around steel pile casting using several arc panels；Second is that fixing a circular gas between steel lifted trunk bottom plate and steel pile casting
Capsule.During the above method pours bottom concrete, sliding is easy to produce under buoyancy and concrete gravity effect and leak occurs
Situation, increases construction cost and construction technology is cumbersome.Therefore, at present construction site be badly in need of one kind can be avoided around steel pile casting mix
Solidifying soil outflow, prevents the steel suspended box cofferdam device for plugging of leak.
Summary of the invention
In view of the above shortcomings of the prior art, cunning is generated during being avoided that below steel pile casting the present invention provides one kind
It moves, thus the steel suspended box cofferdam device for plugging for avoiding concrete from revealing and preventing water from leaking into steel lifted trunk.
To achieve the above objectives, the present invention is realized through the following technical scheme:
A kind of device for plugging for steel suspended box cofferdam, including device noumenon, described device ontology includes top panel, described
Top panel offers the upper port mutually agreed with the outer diameter of steel pile casting, is vertically provided with around the upper port for nested institute
The conical sleeve of steel pile casting is stated, the lower port of the conical sleeve is provided with the lower baffle plate of hollow structure.
Longitudinal stiffened panel is provided in the exterior side wall of the conical sleeve.
The range of the gradient coefficient of the conical sleeve is 0.2-0.3.
The internal diameter of the conical sleeve upper port is greater than the outer diameter 20-24cm of the steel pile casting.
The internal diameter of the conical sleeve lower port is greater than the outer diameter 9-14cm of the steel pile casting.
The internal diameter of the lower baffle plate is greater than the outer diameter 3-6cm of the steel pile casting.
Compared with the prior art, the invention has the advantages that: by the guiding role of conical sleeve, guide the envelope poured
Base concrete flows to lower baffle plate, and the gap between steel pile casting and lower baffle plate is blocked by doughnut sandbag, good airproof performance, is not easy to make coagulation
Soil outflow；By the bottom keel on the through-hole top in the middle part of steel lifted trunk bottom plate, the gap between steel pile casting and overhead gage can be enhanced
Sealing effect, be effectively prevented from concrete leakage.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Fig. 2 is the longitudinal sectional drawing of the present invention in the operating condition.
Appended drawing reference: the bottom 1- keel；The anti-segregating concrete of 2- self-compaction microdilatancy；3- steel pile casting；4- overhead gage；5- is longitudinal
Stiffened panel；6- lower baffle plate；7- conical sleeve；8- steel lifted trunk bottom plate；9- doughnut sandbag.
Specific embodiment
The present invention is described further below with reference to embodiment.
As shown in attached drawing 1-2, a kind of device for plugging for steel suspended box cofferdam, including device noumenon, device noumenon include
Top panel 4, top panel 4 offer the upper port mutually agreed with the outer diameter of steel pile casting 3, are vertically provided with and are used for around upper port
The conical sleeve 7 of nested steel pile casting 3, the lower port of conical sleeve 7 are provided with the lower baffle plate 6 of hollow structure, the internal diameter of lower baffle plate 6
Greater than the outer diameter 3-6cm of steel pile casting 3, longitudinal stiffened panel 5, the gradient of conical sleeve 7 are provided in the exterior side wall of conical sleeve 7
The range of coefficient is 0.2-0.3, and the internal diameter of 7 upper port of conical sleeve is greater than the outer diameter 20-24cm of steel pile casting 3, under conical sleeve 7
The internal diameter of port is greater than the outer diameter 9-14cm of steel pile casting 3.Steel lifted trunk bottom plate 8 is provided with through-hole, internal diameter and the steel pile casting 3 of through-hole
Outer diameter mutually agrees with, and is provided with bottom keel 1 above the steel lifted trunk bottom plate 8 around through-hole, can be to avoid outside water steel pile casting 3 around
Concrete outflow；Gap between lower baffle plate and steel pile casting is filled by doughnut sandbag 9, leak stopping king or Anchor Agent, can be effective
Ground avoids concrete from leaking outside.
When work, the lower edge of overhead gage 4 ride upon steel lifted trunk bottom plate 8 on along upper, steel lifted trunk is transferred under water
Behind position, conduit is arranged around steel pile casting 3, the anti-segregating concrete 2 of self-compaction microdilatancy is then poured under water, protects until by steel
Cylinder 3 is filled up with 8 gap of steel lifted trunk bottom plate, and bottoming concrete thickness reaches design thickness；After pouring and finishing 72 hours, and coagulation
When native compression strength is greater than the 70% of design compression strength, start to draw water to steel suspended box cofferdam.
What has been described above is only a preferred embodiment of the present invention, but the invention is not limited to above-mentioned specific embodiment parties
Formula without departing from the concept of the premise of the invention, can also be made several for those of ordinary skill in the art
Modification and improvement, these are all within the scope of protection of the present invention.
