Description
Technical field
The utility model belongs to the basic field of bridge, including deep water foundation and land basis.
Background technology
With the development of domestic bridge construction, large bridge basis continuously emerges.Bridge foundation common at present mainly has
Pile foundation, Extended chemotherapy, well foundation.Extended chemotherapy is affected by geological conditions, less in coating is thicker or deep water
It uses；Pile foundation use scope is most wide, but to large bridge basis, larger using pile foundation, engineering cost is more；And open caisson
Soil rigidity is big, good integrity, there is larger development space in bridge construction.
Current well foundation cutting shoe and the borehole wall are integral, and to ensure that open caisson smoothly sinks, are reducing open caisson bottom surface just
Face earth resistance is typically designed as wedge shape in the borehole wall and partition wall bottom cutting shoe.Using current structure, there are problems that two：
1, cutting shoe reduces the area of open caisson bottom using wedge shape.Since open caisson is in sinking watching, it is primarily subjected to conduct oneself with dignity
The vertical moment of flexure generated, open caisson bottom are tension, and according to wedge structure, tension area is smaller, need to carry out part to bottom and add
Strength is managed, and it is more to increase quantities.
2, consider borehole wall stress, cutting shoe does wedgewise, but still retains one fixed width；Meanwhile to ensure to turn in well sinking
Sand causes the external soil body to be poured in into well, influences structure safety and attitude stabilization, need to ensure that cutting shoe is inserted into a depthkeeping in soil
Degree.Cause the borehole wall during well sinking as a result, bearing area is big, reduces subsidence factor, causes certain be stranded
It is difficult.
Therefore, current well foundation cutting shoe structure has certain on economy, convenience for construction or reasonable stress
Defect.
Utility model content
The purpose of this utility model is that：A kind of reasonable stress, better economy are provided, while being constructed again conveniently
Novel caisson wall cutting shoe structure.
The purpose of this utility model is realized by following technical proposals：
A kind of assembled caisson wall cutting shoe structure, borehole wall cutting shoe include the integral plate elevationally outward of connection, medial shaft
To plate, level board and stiffener, borehole wall cutting shoe is assemblied in by Screw arbor with nut at both-ends on caisson wall；Elevationally outward outside the plate fitting borehole wall
Side, inside vertical plate are bonded on the inside of the borehole wall, and level board is bonded borehole wall bottom, elevationally outward by passing through between plate and inside vertical plate
The Screw arbor with nut at both-ends of the borehole wall is hinged with the borehole wall, and plate and inside vertical plate stretch out borehole wall bottom hereinafter, and plate elevationally outward elevationally outward
It is longer than inside vertical plate, the stiffener of right angled triangle is located at level board lower section, vertical connection plate, inside vertical plate elevationally outward
And level board, stiffener surround the borehole wall sword of right angled triangle section structure with plate, inside vertical plate and level board elevationally outward
The blade tip of foot.
In this patent, which is assembled, and entire cutting shoe is monoblock type, and cutting shoe section is triangle, and blade tip is just
In insertion soil；Entire cutting shoe structure is connected as entirety with open caisson well bore using Screw arbor with nut at both-ends.Fabricated cutting shoe and open caisson well
Be connected as between body it is hinged, well bore by it is curved when be suitable for open caisson deformation, do not participate in well bore stress directly, as a result, open caisson bottom
Wide arrangement can be used, improve forced area, improve open caisson bottom stress.
In addition, caisson wall cutting shoe is using two pieces of vertical plates, level board and stiffener composition, wherein borehole wall plate elevationally outward
More than inner wall vertical plate.Using this construction, during suck sediment subsidence, cutting shoe can keep being inserted into soil, and the shaft bottom soil body is taken sky,
Convenient for well sinking, and it effectively prevent founding.
Alternatively, plate and inside vertical plate can be vertically free to slide with respect to the borehole wall elevationally outward.
As further selection, vertical slotted hole is opened up in plate and inside vertical plate elevationally outward, Screw arbor with nut at both-ends passes through
The slotted hole is connect with the borehole wall.In the program, to complete being hinged between cutting shoe structure and well bore, Screw arbor with nut at both-ends is in cutting shoe structure
Slotted hole is set in two pieces of vertical plates being affixed with well bore, and cutting shoe structure can be vertical free to slide.
Alternatively, plate stretches out borehole wall bottom or less not less than 2m elevationally outward, and the blade tip of borehole wall cutting shoe stretches out borehole wall bottom
Not less than 2m.In the program, further ensure that open caisson quickly sinks, and effectively prevent founding.
The aforementioned main scheme of the utility model and its each further selection scheme can be freely combined to form multiple schemes,
The scheme that can be used and be claimed for the utility model；And the utility model, (each non conflicting selection) selection between and
It can also be freely combined between other selections.Those skilled in the art are after understanding the present invention program according to the prior art and public affairs
Know that common sense can be illustrated there are many combination, is the claimed technical solution of the utility model, does not do exhaustion herein.
The beneficial effects of the utility model：The utility model is a kind of reasonable stress, better economy, at the same construct again compared with
Novel caisson wall cutting shoe structure for convenience.
